Less Risk, Faster Product Development and Introduction
There have been quite a few articles lately about the upcoming Bulldozer refresh from AMD, but a lot of the information that they have posted is not new. I have put together a few things that seem to have escaped a lot of these articles, and shine a light on what I consider the most important aspects of these upcoming releases. The positive thing that most of these articles have achieved is increasing interest in AMD’s upcoming products, and what they might do for that company and the industry in general.
The original FX-8150 hopefully will only be a slightly embarrasing memory for AMD come Q3/Q4 of this year.
The current Bulldozer architecture that powers the AMD FX series of processors is not exactly an optimal solution. It works, and seems to do fine, but it does not surpass the performance of the previous generation Phenom II X6 series of chips in any meaningful way. Let us not mention how it compares to Intel’s Sandy Bridge and Ivy Bridge products. It is not that the design is inherently flawed or bad, but rather that it was a unique avenue of thought that was not completely optimized. The train of thought is that AMD seems to have given up on the high single threaded performance that Intel has excelled at for some time. Instead they are going for good single threaded performance, and outstanding multi-threaded performance. To achieve this they had to rethink how to essentially make the processor as wide as possible, keep the die size and TDP down to reasonable sizes, and still achieve a decent amount of performance in single threaded applications.
Bulldozer was meant to address this idea, and its success is debatable. The processor works, it shows up as an eight logical core processor, and it seems to scale well with multi-threading. The problem, as stated before, is that it does not perform like a next generation part. In fact, it is often compared to Intel’s Prescott, which was a larger chip on a smaller process than the previous Northwood processor, but did not outperform the earlier part in any meaningful way (except in heat production). The difference between Intel and AMD in this aspect is that as compared to Prescott, Bulldozer as an entirely new architecture as compared to the Prescott/Northwood lineage. AMD has radically changed the way it designs processors. Taking some lessons from the graphics arm of the company and their successful Radeon brand, AMD is applying that train of thought to processors.

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.

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.

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.

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.

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.
Get Out the Microscope
AMD announced their Q1 2012 earnings last week, which turned out better than the previous numbers suggested. The bad news is that they posted a net loss of $590 million. That does sound pretty bad considering that their gross revenue was $1.59 billion, but there is more to the story than meets the eye. Of course, there are thoughts of “those spendthrift executives are burying AMD again”, but this is not the case. The loss lays squarely on the GLOBALFOUNDRIES equity and wafer agreements that have totally been retooled.
To get a good idea of where AMD stands in Q1, and for the rest of this year, we need to see how all these numbers actually get sorted out. Gross revenue is down 6% from the quarter before, which is expected due to seasonal pressures. This is right in line with Intel’s seasonal downturn, and in ways AMD was affected slightly less than their larger competitor. They are down around 2% from last year’s quarter, and part of that can be attributed to the continuing hard drive shortage that continued to affect the previous quarter.

Tagged: amd, Cyclos, piledriver
AMD has its own announcements about power consumption for the International Solid-State Circuits Conference this week. A few days ago we reported on Intel’s success integrating Wi-Fi transceivers into the CPU to reduce power consumption. Cyclos Semiconductor discussed their resonant clock mesh (RCM) technology which reduces waste energy dissipated when keeping the chip synchronized. AMD announced that this technology would be introduced in their upcoming Piledriver APUs and Opteron processors.
Excuse me, good sir. Do you have the time?
Tom’s Hardware put up an article to discuss the announcement with a small explanation of what is going on.
Inductive-capacitive oscillators are leveraged in mesh-based high-performance clock distribution networks to deliver "high-precision timing while dissipating almost no power." In effect, RCM promises to recycle clock power to enable lower power consumption or higher clock speeds.
For a more specific explanation, I turned to Josh Walrath. Chips are timed by a clock signal -- any overclocker will attest to that. Over time chips became larger and more complex which of course requires a larger and more complex system to propagate the clock signal through. Slowly but surely those circuits became large enough that the energy they dissipate simply by being powered becomes less and less negligible.
What Cyclos contributes is cleverly using inductor-capacitor circuits to keep the energy stored in the clock circuit mesh. With more of the energy stored in the mesh it just requires a small energy shove to trigger the signal after the initial charge. Also, less energy lost also means less heat dissipation which helps your battery as well as your heatsink.
Cyclos Semiconductor states that power savings are between 5 to 30 percent dependent on the chip design. In AMD’s case, they expect approximately 5 to 10 percent power savings in their Piledriver implementation. While AMD is the first implementation of Cyclos’ technology, it is not known what Intel currently has done or will potentially do to solve the problem.

Tagged: amd, piledriver, Seoul, Abu Dhabi, fad
One of the many interesting bits of information AMD disseminated at this years FAD started some conjecture about possible problems with Piledriver. It seems that somewhere along the line AMD dropped a module on the Seou chip bringing its core count down from 10 to 8. Once the hue and cry died down a bit a theory propounded by SemiAccurate offered a sensible theory for the change. It seems likely that AMD initially developed this family of chips with the belief that DDR4 would have made it to market by now, perhaps in compensation for the delay in adopting DDR3. Unfortunately DDR4 is nowhere to be seen outside of testing laboratories which has had an effect on AMD's development plans. Without new memory there is no extra memory bandwidth which will in turn starve the extra cores on the chip and likely slow the performance of all of the cores. Instead AMD opted to trim out the extra cores and as a benefit they get to utilize their existing sockets as opposed to introducing another one.
"A lot of people are in a tizzy because AMD (NYSE:AMD) has changed the upcoming Seoul CPU from 10 to 8 cores. The general responses ranges from AMD incompetence to apocalypse, but all it really signals is a lack of technical understanding on their behalf.
The slide in question was the server roadmap we wrote up here. It introduces Piledriver cored Abu Dhabi and Seoul chips, successors to the Bulldozer based Interlagos and Valencia respectively. The base part has 4 modules/8 cores, and the bigger variant is two of those in a package. The big controversy is that they were supposed to be 5 module/10 core parts."

AMD Gives a Glimpse of the Near Future
AMD has released an updated roadmap for these next two years, and the information contained within is quite revealing of where AMD is going and how they are shifting their lineup to be less dependent on a single manufacturer. The Financial Analyst Day has brought a few surprises of where AMD is headed, and how they will get there. Rory Read and Mark Papermaster have brought a new level of energy to the company that seemingly has been either absent or muted. Sometimes a new set of eyes on a problem, or in this case the attitudes and culture of a company, can bring about significant changes for the positive. From what we have seen so far from Rory and company is a new energy and direction for AMD. While AMD is still sticking to their roots, they are looking to further expand upon their expertise in some areas, all the while being flexible enough to license products from other companies that are far enough away from AMD's core competence that it pays to license rather than force engineers to re-invent the wheel.
The roadmaps cover graphics, desktop, mobile, and server products through 2013.
This first slide is a snapshot of the current and upcoming APU lineup. Southern Islands is the codename for the recently released HD 7000 series of desktop parts. This will cover products from the 7700 level on up to the top end 7990. Of great interest are the Brazos 2.0 and Hondo chips. AMD had cancelled the "Krishna" series of chips which would have been based on Bobcat cores up to 4 on 28 nm. Details are still pending, but it seems Brazos 2.0 will still be 40 nm parts but much more refined so they can be clocked higher and still pull less power. Hondo looks to be the basic Brazos core, but for Ultra Low Power (lower clocks, possibly disabled units, etc.) which would presumably scale to 5 watts and possibly lower.

Intel is the driving force behind the Ultrabook platform, a category of thin and light notebooks that are ideally less than $1,000 USD and deliver solid mobile performance and battery life. AMD is still playing catch up in CPU performance; however, they have been moderately successful with their Llano APU parts due to the better integrated GPU versus Intel's graphics processor. With Trinity, the successor to Llano, AMD is claiming up to 25% faster CPU performance and a 50% increase in graphics processor performance, and all while sipping half the power of current Llano chips.
The 17 watt TDP Trinity die.
It seems that AMD has seen the Ultrabook boom that Intel is experiencing and wants a piece of the action. Thanks to the Trinity performance improvements and power sipping TDPs, AMD is confident that it can design and market thin and light notebooks of their own. They plan to market their notebooks as "Ultrathins." Exact hardware specifications of the Ultrathins are not known. We do know that they will be powered by dual and quad core 17 watt TDP versions of the AMD Trinity APU, which you can read more about here. The company is planning for its Ultrathins to start at $500 USD, a few hundred less than the lowest cost Ultrabooks from Intel. Beyond that, we can only speculate. Fortunately, we may not have to wait long for more information as AMD plans to reveal more information about their Ultrathin strategy next month at their financial analyst meeting, according to Ars.

Tagged: VLIW-4, trinity, piledriver, CES, APU, amd
Today at CES, the Consumer Electronics Show, we got to see a demonstration by AMD of an AMD powered computer running dual monitors. Only, it was not just a dual monitor pushing desktop computer. In a surprise twist, AMD took the side panel off of the desktop computer to reveal that it was actually a laptop computer using their next generation AMD Trinity APU that was driving the game on one display, and the windows desktop on the other display. Even more, on the laptop screen itself, it was playing a 720p video.
Here you can see the two displays that the Trinity powered laptop was driving with Dirt 3 on the left monitor and the Windows desktop on the right one where a video conversion was happening in the background. AMD did not get into any details regarding the transcode, however.
This is the "desktop" computer case that they opened up to reveal that it was, in fact, a Trinity laptop that was driving all the displays.
A die shot of the upcoming Trinity APU (Accelerated Processing Unit) sitting next to a USB flash drive. Specifications of the Trinity APUs have not yet been released by AMD; however, if this leak holds true the Trinity APUs will have either two or four Piledriver CPU cores and TDP (thermal design power) of 65 W, 100 W, and 125 Watts (depending on particular chip). Clock speeds will further vary between 2.2 and 3.8 GHz at stock speeds (will run a bit faster with Turbo Core 3.0). The GPU aspect will be clocked between 563 MHz and 711 MHz and is based on the VLIW4 technology of the Cayman graphics Cards (69xx). They estimate that it will deliver up to 30% more performance versus current Llano chips and will support all the fancy new X86 instruction sets like AVX and AES-NI. A nice boost and hopefully the real specifications will come close to this (or be even better, of course).
Update: Another interesting bit of information is that AMD will have a low power Trinity APU with a TDP of 17 watts and will supposedly deliver the same level of performance as the current Llano chips (that draw twice the power).
Update: AMD has stated Trinity will deliver a 25% increase in CPU performance and a 50% increase in GPU performance versus current Llano APUs. Stay tuned to PC Perspective for more Trinity info as it develops.
