Tagged: widi, Intel, awd, amd wireless display, amd, AFDS
While perusing through the listings and descriptions of sessions and presentations for the upcoming AMD Fusion Developer Summit, I came across an interesting one that surprised me. Tomorrow, June 11th, at 5:15pm PST, you can stop by the Grand Hyatt in Bellevue to learn about the upcoming AMD Wireless Display technology.
AWD (AMD Wireless Display) is a multiple-platform application family to enable wireless display technologies much in the same way that Intel has been pushing with WiDi. While Intel's take on it requires very specific Intel wireless controllers and is only recently, with the release of Ivy Bridge, getting the full-steam push from Intel, AMD's take on it is quite different.
Intel introduced WiDi in 2010
According to the brief on this AFDS session, AMD wants to create an API and SDKs for application developers to integrate AWD into software and to leverage the WiFi Alliance for an open-standards compliant front-end. Using AMD APUs, the goal is provide lower latency for encoded video and audio while still using the required MPEG2TS wrapper. We are also likely to learn that AMD hopes to make AWD open to a wider array of wireless devices.
AMD often takes this "open" approach to new technologies with mixed results - CUDA has been in place for many years while the adoption of OpenCL is only starting to take hold and 3D Vision still is the standard for 3D gaming on the PC.
After having quite a few chances to use Intel's Wireless Display (WiDi) technology myself I can definitely say that the wireless approach is the one I am most excited with and that has the most potential to revolutionize the way we work with displays and computing devices. I am eager to see what partners AMD has been working with and what demonstrations they will have for AWD next week.

Phoronix have been very busy lately, getting their heads around the functionality of Ivy Bridge on Linux and as these processor are much more compatible than their predecessors it has resulted in a lot of testing. The majority of the testing focused on the performance of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64 on an i7-3770K using a wide variety of programs and benchmarks. Their initial findings favoured GCC over all other compilers as in general it took top spot, with LLVM having issues with some of their tests. They then started to play around with the instruction sets the processor was allowed to use, by disabling some of the new features they could emulate how the Ivy Bridge processor would perform if it was from a previous generation of chips, good to judge the improvement of raw processing power. They finished up by testing its virtualization performance, with BareMetal, the Kernel-based Virtual Machine virtualization and Oracle VM VirtualBox. You can see how they compared right here.
"From an Intel Core i7 3770K "Ivy Bridge" system here is an 11-way compiler comparison to look at the performance of these popular code compilers on the latest-generation Intel hardware. Among the compilers being compared on Intel's Ivy Bridge platform are multiple releases of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64."

Tagged: hsa, fusion, amd, AFDS
One of the best show experiences I had last year was a surprise to me - AMD's first annual Fusion Developer Summit (AFDS) was hosted in the Seattle / Bellevue area. I say that it was a surprise only because the inaugural year for vendor-specific shows like this tend to be pretty bland and lack interesting information, but that wasn't the case in 2011. We saw ARM get on stage with AMD to talk about the idea of "dark silicon" and how to prevent it, we saw the first AMD Trinity notebook and even got details of the Tahiti GPU architecture well ahead of release.
We expect even better things in 2012.
While I don't know exactly what surprises will be on display this year I am looking forward to seeing the improvement from software developers after having another 12 months to work on APU-accelerated applications. HSA (heterogeneous system architecture) has been getting a lot of buzz from AMD and the industry as we push towards a combined memory address space and the ultimate acceleration of programs across both serialized and parallel processors on the same die.
If you are in the Seattle / Bellevue area and you have the ability to attend AFDS, I would highly encourage you to do so. You'll have access to:
- Never before seen demos
- Technical tracks and sessions to learn about HSA and programming for it
If you can't make it though, you should definitely follow the whole event right here at PC Perspective - the easiest way is to keep track of our AFDS tag to make sure you don't miss any of the potentially industry shifting news!
You can also expect us to have a live blog from the event as well!

Today AMD is officially releasing their Brazos 2.0 parts. This is a case of good news/bad news for the company. The good news is that they have an updated product that is based on their very successful Brazos 1.0 platform and that particular part has sold over 30 million units and is included in some 160 designs. The bad news is that AMD did not improve the product dramatically over what we previously had.
While Brazos will not beat these Intel offerings in pure performance, they do match up nicely in terms of price and battery life.
It is well known that AMD cancelled their original Bobcat 2.0 28 nm parts last fall (Krishna and Wichita), and instead worked on improving the fabrication of the current Brazos APUs. Little is known as to why those original 28 nm parts were cancelled, but perhaps the overriding reason is that there simply would not be enough 28 nm production through the first three quarters of 2012 to enable AMD to adequately meet demand on these parts (all the while sacrificing higher margin GPU wafer orders on the 28 nm node). We also must consider that AMD could have been counting on GLOBALFOUNDRIES to have their flavor of 28 nm HKMG process up and running, which of course at this time it is not.
These new Brazos 2.0 chips are still manufactured on TSMC’s 40 nm process, but that particular process is very mature at this time. This has allowed AMD and TSMC to squeeze every last drop of performance and efficiency out of the aging 40 nm node, and in so doing has allowed AMD a bit more headroom when it comes to the Zacate APUs that Brazos 2.0 is based off of. The two new processors are the E2-1800 and the E2-1200.
The E2-1800 is a dual core Bobcat CPU featuring an APU with 80 stream units based on the older HD 5000 series of parts. AMD has renamed the GPU to the HD 7340, though it has little in common with the GCN (Graphics Core Next) based HD 7000 graphics units. AMD increased the core CPU speed from the E-450 by 50 MHz and the GPU portion by 80 MHz. This gives the E2-1800 a core clockspeed of 1.7 GHz and the graphics runs at a brisk 680 MHz. This continues to be an 18 watt TDP part and the die size is the same 75 mm squared.

So, apparently PC gamers are big fans of Diablo III, to the tune of 3.5 million copies sold in the first 24 hours. That means there are a lot of people out there looking for information about the performance they can expect on various harware configurations with Diablo III. Since we happened to have the two newest mobile processors and platforms on-hand, and because many people seemed to assume that "just about anything" would be able to play D3, we decided to put it to the test.
In our previous reviews of the AMD Trinity and Intel Ivy Bridge reference systems, the general consensus was that the CPU portion of the chip was better on Intel's side while the GPU portion was still weighted towards the AMD Trinity APU. Both of these CPUs, the A10-4600M and the Core i7-3720QM, are the highest end mobile solutions from both AMD and Intel.
The specifications weren't identical, but again, for a mobile platform, this was the best we could do. With the AMD system only having 4GB of memory compared to the Ivy Bridge system with 8GB, that is one lone "stand out" spec. The Intel HD 4000 graphics offer a noticeable upgrade from the HD 3000 on the Sandy Bridge platform but AMD's new HD 7660G (based on Cayman) also sees performance increase.
We ran our tests at 1366x768 with "high" image quality settings and ran through a section of the early part of the game a few times with FRAPs to get our performance results. We did also run some tests to an external monitor at 1920x1080 with "low" presets and AA disabled - both are reported in the video below. Enjoy!

Tagged: Intel, fab
Intel has released an animated video and supplementary PDF document to explain how Intel CPUs are manufactured. The video is more “cute” than anything else although the document is surprisingly really well explained for the average interested person. If you have ever wanted to know how a processor was physically produced then I highly recommend taking about a half of an hour to watch the video and read the text.
If you have ever wondered how CPUs came to be from raw sand -- prepare to get learned.
Intel has published a video and accompanied information document which explains their process almost step by step. The video itself will not teach you too much as it was designed to illustrate the information in the online pamphlet.
Not shown is the poor sandy bridges that got smelted for your enjoyment.
Rest in got
My background in education is a large part of the reason why I am excited by this video. The accompanied document is really well explained, goes into just the right amount of detail, and does so very honestly. The authors did not shy away from declaring that they do not produce their own wafers nor did they sugarcoat that each die even on the same wafer could perform differently or possibly not at all.
You should do yourself a favor and check it out.

Dell announced today that is going to help enable the world of the ARM-based server ecosystem by enabling key hyperscale customers to access and develop on Dell's own "Copper" ARM servers.
Dell today announced it is responding to the demands of our customers for continued innovation in support of hyperscale environments, and enabling the ecosystem for ARM-based servers. The ARM-based server market is approaching an inflection point, marked by increasing customer interest in testing and developing applications, and Dell believes now is the right time to help foster development and testing of operating systems and applications for ARM servers.
Dell is recognized as an industry leader in both the x86 architecture and the hyperscale server market segments. Dell began testing ARM server technology internally in 2010 in response to increasing customer demands for density and power efficiency, and worked closely with select Dell Data Center Solutions (DCS) hyperscale customers to understand their interest level and expectations for ARM-based servers. Today's announcement is a natural extension of Dell's server leadership and the company's continued focus on delivering next generation technology innovation.
While these servers are still not publicly available, Dell is fostering the development of software and verification processes by seeding these unique servers to a select few groups. PC Perspective is NOT one of them.
Each of these 3U rack mount machines includes 48 independent servers, each based around a 1.6 GHz quad-core Marvell Armada XP SoC. Each of the sleds (pictured below) holds four discrete server nodes, each capable of as much as 8GB of memory on a single DDR3 UDIMM. Each node can access one 2.5-in HDD bay and one Gigabit Ethernet connection.
Click for a larger view
Even though we are still very early into the life cycle of ARM architectures in the server room, Dell claims that these systems are built perfectly for web front-ends and Hadoop environments:
Customers have expressed great interest in understanding ARM-based server advantages and how they may apply to their hyperscale environments. Dell believes ARM infrastructures demonstrate promise for web front-end and Hadoop environments, where advantages in performance per dollar and performance per watt are critical. The ARM server ecosystem is still developing, and largely available in open-source, non-production versions, and the current focus is on supporting development of that ecosystem. Dell has designed its programs to support today's market realities by providing lightweight, high-performance seed units and easy remote access to development clusters.
There is little doubt that Intel will feel and address this competition in the coming years.

Tagged: z2670, windows 8, dell, clover trail, atom
In a leaked slide posted by Neowin.net, details of Dell's upcoming Latitude 10 tablet are coming to light, including hardware specifications like the Intel Atom Z2670 "Clover Trail" SoC.
This 10.1-in Windows 8 based tablet will include a 1366x768 display with a capacitive multi-touch screen and an optional stylus accessory. Weighing in at just over 1.5 pounds, the Latitude 10 is just slightly heavier than the latest generation of iPad (1.46 pounds).
Intel's upcoming Atom processor, the Z2670, will be at the core of the design and will be based on the "Clover Trail" design, a slightly faster and updated version of "Medfield" we have seen implemented on mobile phones early in 2012. With dual-cores capable of HyperThreading, and the ability to enter into "Burst Mode" which offers "quick bursts of extra performance when called upon", the Atom Z2670 should be capable of presenting a reasonable Windows 8 experience.
Other specifications include 2 GB of DDR2-800 lower power memory, up to a 128 GB SSD, 2 and 4 cell swappable batteries and front plus rear facing cameras.
With Computex 2012 right around the corner in Taipei, Taiwan, we expect to see quite a few more tablets and hybrid machines based on Windows 8 including Intel Atom-powered devices as well as ARM-based devices running Windows 8 RT.

Intel has released a report about their environmental efforts in terms of manufacturing efficiency, waste, and the efficiency of their products themselves. Their 2020 mobile and data center product line is expected to use 25-fold less power than their 2010 product line. Intel is hoping to use less water and consume 1.4 TWh less energy between 2012 and 2015 in their manufacturing with no chemical waste to landfill by 2020.
It is not easy been green.
… But, especially now, Intel can afford to try.
The chip manufacturer has set some goals for themselves to decrease their impact on the environment. These plans were published in their 2011 Corporate Responsibility Report (pdf), released last week. The plan highlights goals extending out as far as 2020.
It would seem that for Intel foresight is also 2020.
Yes, those puns were terrible, I admit it.
One of the forefront issues raised is alterations to their supply chain. Their raw materials have been addressed -- not just for eco-friendliness -- but also for human rights violations. By the end of 2012 Intel intends to validate that all tantalum would be “conflict-free” with the other three minerals verified by the end of 2013.
On the topic of environmental impact Intel is also intending on reducing their electrical and water usage at their manufacturing plants. A total of 1.4 TWh of energy is expected to be reduced from 2012 through 2015. Intel is also lauding their solar initiatives although they fell short of committing to any specific future endeavors in clean energy in this report.
Lastly, Intel claims that their mobile and data center products will consume 25-fold less power than their 2010 counterparts. Obviously such a statement falls more under gloating than a vow to promote sustainability but it is respectable none-the-less.

Tagged: ultrabook, trinity, cloud computing, cloud, amd
Bloomberg Businessweek reports AMD CEO Rory Read claims that his company will produce chips which are suited for consumer needs and not to crunch larger and larger bundles of information. They also like eating Intel’s bacon -- the question: is it from a pig or a turkey?
Read believes there is “enough processing power on every laptop on the planet today”.
The argument revolves around the shift to the cloud, as usual. It is very alluring to shift focus from the instrument to the data itself. More enticing: discussing how the instruments change to suit that need; this is especially true if you develop instruments and yearn to shift anyway.
Don’t question the bacon…
AMD has been trusting that their processors will be good enough and their products will differentiate in other ways such as with graphics capabilities which they claim will be more important for cloud services. AMD hopes that their newer laptops will steal some bacon from Intel and their ultrabook initiative.
The main problem with the cloud is that it is mostly something that people feel that they want rather than actually do. They believe they want their content controlled by a company for them until it becomes inaccessible temporarily or permanently. They believe they want their information accessible in online services but then freak out about the privacy implications of it.
The public appeal of the cloud is that it lets you feel as though you can focus on the content rather than the medium. The problem is that you do not have fewer distractions from your content -- just different ones -- and they rear their head once or twice in isolation of each other. You experience a privacy concern here and an incompatibility or licensing issue there. For some problems and for some people it makes more sense to control your own data. It will continue to be important to serve that market.
And if crunching ends up being necessary for the future it looks like Intel will be a little lonely at the top.

AMD's A10-4600M APU has finally arrived, showing off an enhanced Piledriver core and a new Northern Islands based graphics core. This is a big step up from Llano in terms of general processing power but not a huge improvement over Bulldozer chips, though the raised clock speed does help it in general tasks. Unfortunately the AMD still chip lags far behind the performance of Intel's mobile i5 processors and while the graphics are certainly more powerful on Trinity they still aren't up to an impressive level of performance. The Tech Report liked the high end A10-4600M but think that Trinity's low power chips are really going to shine in inexpensive ultraportable machines.
You can also check out Matt's review of Llano in a reference laptop from AMD for more information.
"AMD has pulled the curtains back on Trinity, its next-generation APU, which features new Piledriver CPU cores and Northern Islands-derived integrated graphics. Join us as we outline Trinity's architecture and run it through a whole host of benchmarks, from old staples to OpenCL-accelerated apps and "inside the second" gaming tests."

- AMD Radeon HD 7000 Series graphics for an increase of graphics performance up to 56% over the previous generation. Combined, the CPU and GPU cores deliver more than 700 gigaflops of computing performance – several times more than the fastest x86 CPUs – to boost performance of hundreds of applications;
- Up to 12 hours of battery life through CPU and GPU power enhancements, with clear battery life leadership in notebook form factors.
“The latest OEM notebooks, ultrathins, All-in-Ones and desktops based on the new AMD A-Series APU enable the best video and gaming experiences, highly responsive performance with AMD Turbo CORE, and accelerate an ever-increasing range of productivity and multimedia applications -- in sleek, stylish designs at price points that make sense,” said Chris Cloran, corporate vice president and General Manager, AMD Client Business Unit. “Our 2nd-Generation AMD A-Series APU is a major step forward in every performance and power dimension, allowing users to enjoy a stunning experience without having to give up the things that matter to them most. This experience doesn’t stop at mainstream notebooks. It carries over into affordable ultrathin form factors featuring the latest in AMD Radeon graphics.”
The Growing AMD Accelerated Application Ecosystem
The developer ecosystem continues to gravitate to the unmatched level of compute and unique processing capabilities of the APU as more than 100 applications and games are now accelerated by AMD APUs. The 2nd-Generation AMD A-Series APU gives users superior Web-based video experience thanks to plug-ins for Google Chrome, Firefox and Internet Explorer 9 that make it easy for consumers to turn on AMD Steady Video technology. Recent applications that have been optimized for use on AMD A-Series APUs include Adobe Photoshop CS6, WinZip 16.5 and VLC Media Player. AMD A-Series APUs are also well-positioned to take advantage of the upcoming transition to the Windows 8 operating system.
“We are excited for the introduction of the 2nd-Generation AMD A-Series APU and are confident it will continue the great work Microsoft and AMD have done together on the A-Series APU,” said Aidan Marcuss, senior director, Windows Business Planning, Microsoft Corp. “We look forward to seeing the A-Series APU in action with Windows 8 to deliver a great user experience across a variety of hardware.”
For developers who want to engage in the industry’s move toward heterogeneous computing, the upcoming AMD Fusion12 Developer Summit will offer them a unique opportunity to enhance their knowledge base. More information on AFDS can be found here.
With more than 12 hours of ‘resting’ battery life, AMD is now an industry leader in notebook battery-life performance. The 2nd-Generation AMD A-Series APU delivers increased levels of performance, while consuming half the power as its predecessor.
These gains can be attributed to the new power-optimized “Piledriver” CPU core, as well as to AMD Start Now technology, which is designed to maximize system responsiveness by quickly entering and exiting low power states. With AMD Start Now, the computer resumes from sleep mode in as few as two seconds and boots to the desktop in as few as 10 seconds.
In ultrathin form factors, AMD enables an uncompromised visual experience thanks to a power-efficient and premium AMD Radeon graphics engine. Consumers can expect to see ultrathin notebooks based on dual-core 17-watt and quad-core 25-watt AMD A-Series APUs. These products will be easily identifiable by aluminum-styled VISION Technology stickers at a range of competitive price points.
As more and more people turn to their computers as the hub for their entertainment, the visual aspect of computing becomes ever more important. To enhance these capabilities, AMD created the AMD HD Media Accelerator – a unique set of technologies that enable the best video quality on a PC. Key features of the HD Media Accelerator include:
- AMD Perfect Picture HD – An image, video processing and display technology that automatically makes images and video better with color vibrancy adjustments, edge enhancement, noise reduction and dynamic contrast fixes;

Tagged: ultrathins, trinity, piledriver, mobile, APU, amd
Last week we detailed the changes and improvements in AMD’s upcoming Trinity Accelerated Processing Units (APU). Today, DigiTimes has confirmed that Trinity will be released later this month. The only catch is that the company is only releasing the mobile Trinity chips in May. The higher end, and higher TDP, parts will not be released until August 2012.
A Trinity APU die next to a USB flash drive
According to their sources, AMD will be pricing the mobile Trinity chips very aggressively. They will offer a cheaper alternative to OEMs as AMD based ultrathins compared to an Ivy Bridge based ultabrook notebook. The low power Trinity chips will have vastly superior GPU execution units, though Ivy Bridge may retain the CPU performance crown. Both chips are able to sip voltage and have low TDPs so it will be interesting to see the results of battery life tests once the chips and notebooks are released and are in the hands of reviewers.
Trinity desktop parts are scheduled for release in August, including the A10-5800K, A10-5700, A8-5600K, and A8-5500. They are also planning lower end A6 and A4 series Trinity APUs.
Beyond Trinity, their sources have indicated that AMD will release very low power Brazos 2.0 processors for ultrathins and Windows 8 tablets that have 18W TDPs in June 2012. Vishera–Piledriver architecture, AM3+ socket–FX series desktop CPUs (no iGPU) will be released sometime in the third quarter of this year (Q3 2012). The FX and Brazos processors include the FX-8350, FX-6300, FX-4320, and the E2-1800 and E1-1200 respectively.
While AMD may not have the lowest manufacturing process, are seemingly dropping employees like flies, and had a huge financial loss due to buying themselves out of GlobalFoundries they are still hanging in there and delivering competitive products for the low to mid-range markets.

Tagged: trinity, piledriver, llnao, fm2, APU, AMD A series
EXP Review has managed to get their hands on a set of AMD slides containing information on one of the company’s upcoming processor lines. The Llano successor, known as Trinity, is a new APU due out later this year that is said to bring increases in performance thanks to several architectural enhancements.
A Trinity APU die sitting next to a USB flash drive
Llano is AMD’s currently available Accelerated Processing Unit, or APU. The chips combine updated “Stars” mobile Phenom II CPU cores and Radeon 6000 series graphics cores into a single package. Further, the APUs contain a PCI-E 2.0 controller, integrated memory controller, and UVD3 hardware video decoding units. Some models also support AMD’s Turbo Core and Hybrid Graphics Technology which allow them to automatically boost CPU clockspeeds when lower GPU usage leaves TDP headroom, and to pair with a discrete Radeon HD 6450, 6570, or 6670 GPU in a Crossfire-like configuration. Built on a 32nm silicon on insulator (SOI) manufacturing process by GlobalFoundries, the APUs employ 1.45 billion transistors and have a die size of 228mm2 for the desktop versions. Desktop parts have TDPs of 65 watts or 100 watts depending on the particular chip and connect to the motherboards using the FM1 socket (which was a new socket for AMD, it has 905 contacts). There are both desktop and mobile Llano parts, though they are essentially the same chips. The mobile parts are scaled down desktop Llano chips that run at lower clockspeeds, top out DDR3 support at 1600MHz (versus DDR3 1866MHz on the desktop parts), have lower TDPs of either 35W or 45W, and use a slightly different socket (FS1).
In our review, and what many other users noted, is that Llano’s CPU performance really left something to be desired. Fortunately for AMD, the GPU portion of the chip delivered on performance and made the APU desirable for certain niches. The low power chips had a place in home theater PCs (HTPCs), cheap desktops, and even budget gaming rigs to an extent. Still, the CPU performance really held Llano back in terms of popularity and adoption among enthusiasts.
Llano APU in action during overclocking and gaming tests.
The upcoming Trinity processors bring quite a few enhancements to the table, foremost of which is a revamped CPU part that ditches the old Phenom II processor cores in favor of updated Piledriver architecture CPU modules. The move to the Piledriver x86 cores promises an increase in IPC, leakage reduction, CAC reduction, and increased clockspeeds according to the leaked slides, but the most important change is the increased performance per clock numbers. The Trinity APUs are set to replace the A8–or performance series of–Llano APUs with quad core Trinity processors that utilize two Piledriver modules that each share 2MB cache for 4MB of total L2 cache. In that respect, Trinity will be similar to Llano in that it does not employ any L3 cache that is shared between the CPU and GPU cores. Interestingly, that may mean that using higher clocked RAM can improve performance on Trinity just as it did with Llano. If true, that would make Trinity’s improved DDR3 support–up to DDR3 2133MHz– all the better. On the GPU side of things, Trinity moves to a “Northern Islands” VLIW4 architecture with up to 384 stream processing units. Although the GPU area is physically smaller, it is said to be more efficient than the GPU cores in Llano APUs. The new GPU core is DirectX 11 and OpenCL 1.1 compliant. Also, it includes an updated hardware tessellator engine and hardware encoding unit (AMD Accelerated Video Converter).
Trinity will continue to offer 65W and 100W TDPs as well as a 35W part. The TDPs are the same as those in Llano, but AMD has managed to lower the voltages needed to run Trinity out of the box. Also, AMD is claiming the new Trinity chips will sip power at idle–as low as 1.08 watts.
Trinity also ratchets up the automatic overclocking with Turbo Core 3 support which can boost the CPU clockspeed up to 19% or the GPU clockspeed up to 20% above stock clocks. Even better, the APU is able to allocate power to either the GPU or CPU depending on which area needs the boost and how much TDP headroom the chip has when doing certain tasks. For example, AMD shows that the A10-4600M APU can downclock the GPU from the default clockspeed of 685MHz to 496MHz, allowing the x86 Piledriver cores to achieve up to a 900MHz overclock at a clockspeed of 3.2GHz. Alternatively, when the GPU is needed, it can run at 685MHz while the CPU sits at 2.3GHz. They are likely not able to push the GPU much further as any more reductions in CPU speeds would need to be much bigger than any accompanying GPU increases. And at that point, the GPU would likely become bottlenecked and the system would be starved of too much CPU power anyway.
The Trinity APUs continue to be based on GlobalFoundries’ 32nm SOI manufacturing process, but this time the chips are slightly larger with a die size of 246mm^2. Although the APU is wholly larger than Llano, they actually have fewer transistors at 1.303 billion versus the 1.45 billion in Llano. Although that may seem like a step in the wrong direction, the new CPU modules and GPU cores are much more efficient than those in Llano so it should all balance out and Trinity should come out on top despite the lower transistor count. The Trinity APUs will also feature an improved instruction set that includes AVX, AVX1.1, FMA3, AES, and F16C which should help the CPU in certain tasks.
Overall, Trinity is looking like an improved part versus Llano, especially in the CPU department. Although AMD’s numbers should be taken with more than a grain of salt, they are claiming 26% better desktop system performance as a result of the CPU overhaul. Granted, Bulldozer was not a CPU powerhouse itself when compared to the competition, but it is–at least on paper–a good design. When paired with a relatively good GPU, as is the case of Trinity, the Piledriver [architecture based] (a refined version of the Bulldozer architecture with some under-the-hood tweaks) cores should at the least not hold the GPU back, and at best make the CPU processor performance good enough to make the Trinity APU all the more desirable to an even wider range of potential buyers. Pricing of the new APUs is still up in the air, but they are set to release later this month if a certain leak is to be believed.
I think that we can expect to see an all around better chip with Trinity, though pricing will be the ultimate factor in determining how popular it is. I suspect that Intel will still carry the CPU crown, but if the price is right, AMD can sell a lot of Trinity chips to builders that only need decent CPUs to support good integrated GPU cores in systems where the GPU is more important. I am anxiously awaiting reviews of the new Trinity chips and hoping that AMD continues to have successful chips with their line of APUs.

Anyone who has been keeping up with the reviews coming out which try overclocking Intel's new Ivy Bridge processor will be familiar with the large amount of power required to hit high frequencies. While the voltages required to overclock Ivy Bridge and its predecessor Sandy Bridge are very similar, Ivy Bridge's stock voltage is lower so the change is greater for Ivy Bridge. That larger increase could be one cause of the higher heat that Ivy Bridge generates. Another theory is that the heatspreader could be a cause as Intel used thermal paste in the design as opposed to the fluxless solder present on SandyB, however other tests have shown that this does not seem to be the case. The Tech Report has gathered together the current facts on this hot topic, so you can check out the numbers for yourself right here.
"Folks across the web have reported some eye-poppingly high temperatures for their overclocked Ivy Bridge processors, leading to some tough questions about the causes. Does Ivy Bridge truly run hotter than its predecessor, Sandy Bridge, and if so, why? We checked into it, and the answers were surprising, to say the least. Have a look."

Intel's latest die shrink and architecture refinement, aka their "Tick", has arrived in the form of Ivy Bridge. This CPU is actually only one third CPU, a third devoted to Intel's HD4000 graphics core, and the final third comprised of a shared L3 cache, memory controller and other IO devices. [H]ard|OCP did an almost direct comparison between Sandy Bridge and Ivy Bridge, with the 2600K having the same amount of cores as the 3770K and only lags behind by 100MHz in raw speed. The overall performance increases and new features that this new architecture were targeted more at the mainstream user than the enthusiast in [H]'s opinion but if you are building a new machine and aren't going for overclocking records then they wholeheartedly recommend Ivy Bridge.
You can catch Ryan's full review right here though you cannot yet buy it.
"The new Ivy Bridge processor has already been well covered across the Internet due to leaks of Intel parts into review sites' hands. So at this point there is little to tell in all honesty. But today we work to tell you what you most likely already know; Ivy Bridge looks to be a very solid product but offers little in the way of an upgrade from Sandy Bridge."

NVIDIA steals Intel’s lunch… analogy. In the process they claim that optimizing your application for Intel’s upcoming many-core hardware is not free of effort, and that effort is similar to what is required to develop on what NVIDIA already has available.
A few months ago, Intel published an article on their software blog to urge developers to look to the future without relying on the future when they design their applications. The crux of Intel’s argument states that regardless of how efficient Intel makes their processors, there is still responsibility on your part to create efficient code.
There’s always that one, in the back of the class…
NVIDIA, never a company to be afraid to make a statement, used Intel’s analogy to alert developers to optimize for many-core architectures.
The hope that unmodified HPC applications will work well on MIC with just a recompile is not really credible, nor is talking about ease of programming without consideration of performance.
There is no free lunch. Programmers will need to put in some effort to structure their applications for hybrid architectures. But that work will pay off handsomely for today’s, and especially tomorrow’s, HPC systems.
It remains to be seen how Intel MIC will perform when it eventually arrives. But why wait? Better to get ahead of the game by starting down the hybrid multicore path now.
NVIDIA thinks that Intel was correct: there would be no free lunch for developers, why not purchase a plate at NVIDIA’s table? Who knows, after the appetizer you might want to stay around.
You cannot simply allow your program to execute on Many Integrated Core (MIC) hardware and expect it to do so well. The goal is not to simply implement on new hardware -- it is to perform efficiently while utilizing the advantages of everything that is available. It will always be up to the developer to set up their application in the appropriate way.
Your advantage will be to understand the pros and cons of massive parallelism. NVIDIA, AMD, and now Intel have labored to create a variety of architectures to suit this aspiration; software developers must labor in a similar way on their end.
