Intel's upcoming 14nm product line, Broadwell, is expected to have six categories of increasing performance. Broadwell-Y, later branded Core M, is part of the soldered BGA family at expected TDPs of 3.5 to 4.5W. Above this is Broadwell-U, which are also BGA packages, and thus require soldering by the system builder. VR-Zone China has a list of seemingly every 15W SKU in that category. 28W TDP "U" products are expected to be available in the following quarter, but are not listed.

As for those 15W parts though, there are seventeen (17!) of them, ranging from Celeron to Core i7. While each product is dual-core, the ones that are Core i3 and up have Hyper-Threading, increasing the parallelism to four tasks simultaneously. In terms of cache, Celerons and Pentiums will have 2MB, Core i7s will have 4MB, and everything in between will have 3MB. Otherwise, the products vary on the clock frequency they were binned (bin-sorted) at, and the integrated graphics that they contain.

These integrated iGPUs range from "Intel HD Graphics" on the Celerons and Pentiums, to "Intel Iris Graphics 6100" on one Core i7, two Core i5s, and one Core i3. The rest pretty much alternate between Intel HD Graphics 5500 and Intel HD Graphics 6000. Maximum frequency of any given iGPU can vary within the same product, but only by about 100 MHz at the most. The exact spread is below.
- Intel HD Graphics: 300 MHz base clock, 800 MHz at load.
- Intel HD Graphics 5500: 300 MHz base clock, 850-950 MHz at load (depending on SKU).
- Intel HD Graphics 6000: 300 MHz base clock, 1000 MHz at load.
- Intel Iris Graphics 6100: 300 MHz base clock, 1000-1100 MHz at load (depending on SKU).
Unfortunately, without the number of shader units to go along with the core clock, we cannot derive a FLOP value yet. This is a very important metric for increasing resolution and shader complexity, and it would provide a relatively fair metric to compare the new parts against previous offerings for higher resolutions and quality settings, especialy in DirectX 12 I would assume.

Probably the most interesting part to me is that "Intel HD Graphics" without a number meant GT1 with Haswell. Starting with Broadwell, it has been upgraded to GT2 (apparently). As we can see from even the 4.5W Core M processors, Intel is taking graphics seriously. It is unclear whether their intention is to respect gaming's influence on device purchases, or if they are believing that generalized GPU compute will be "a thing" very soon.

Tagged: apple, a8, a7, Imagination Technologies, PowerVR
First, Chipworks released a dieshot of the new Apple A8 SoC (stored at archive.org). It is based on the 20nm fabrication process from TSMC, which they allegedly bought the entire capacity for. From there, a bit of a debate arose regarding what each group of transistors represented. All sources claim that it is based around a dual-core CPU, but the GPU is a bit polarizing.
Image Credit: Chipworks via Ars Technica
Most sources, including Chipworks, Ars Technica, Anandtech, and so forth believe that it is a quad-core graphics processor from Imagination Technologies. Specifically, they expect that it is the GX6450 from the PowerVR Series 6XT. This is a narrow upgrade over the G6430 found in the Apple A7 processor, which is in line with the initial benchmarks that we saw (and not in line with the 50% GPU performance increase that Apple claims). For programmability, the GX6450 is equivalent to a DirectX 10-level feature set, unless it was extended by Apple, which I doubt.
Image Source: DailyTech
DailyTech has their own theory, suggesting that it is a GX6650 that is horizontally-aligned. From my observation, their "Cluster 2" and "Cluster 5" do not look identical at all to the other four, so I doubt their claims. I expect that they heard Apple's 50% claims, expected six GPU cores as the rumors originally indicated, and saw cores that were not there.
Which brings us back to the question of, "So what is the 50% increase in performance that Apple claims?" Unless they had a significant increase in clock rate, I still wonder if Apple is claiming that their increase in graphics performance will come from the Metal API even though it is not exclusive to new hardware.
But from everything we saw so far, it is just a handful of percent better.

Tagged: Intel, spreadtrum, rda, Rockchip, SoC
A few months ago, Intel partnered with Rockchip to develop low-cost SoCs for Android. The companies would work together on a design that could be fabricated at TSMC. This time Intel is partnering with Tsinghua Unigroup Ltd. and, unlike Rockchip, also investing in them. The deal will be up to $1.5 billion USD in exchange for a 20% share (approximately) of a division of Tsinghua.
Image Credit: Wikipedia
Intel is hoping to use this partnership to develop mobile SoCs, for smart (and "feature") phones, tablets, and other devices, and get significant presence in the Chinese mobile market. Tsinghua acquired Spreadtrum Communications and RDA Microelectronics within the last two years. The "holding group" that owns these division is apparently the part of Tsinghua which Intel is investing in, specifically.
Spreadtrum will produce SoCs based on Intel's "Intel Architecture". This sounds like they are referring to the 32-bit IA-32, which means that Spreadtrum would be developing 32-bit SoCs, but it is possible that they could be talking about Intel 64. These products are expected for 2H'15.

After the smoke from their previous attempt at testing the i7 5960X CPU Phoronix picked up a Gigabyte X99-UD4-CF and have now had a chance to test Haswell-E performance on Linux. The new processor is compared to over a dozen others on machines running Ubuntu and really showed up the competition on benchmarks that took advantage of the 8 cores. Single threaded applications that depended on a higher clock speed proved to be a weakness as the 4790K's higher frequency allowed it to outperform the new Haswell-E processor. Check out the very impressive results of Phoronix's testing right here.
"With the X99 burned-up motherboard problem of last week appearing to be behind us with no further issues when using a completely different X99 motherboard, here's the first extensive look at the Core i7 5960X Haswell-E processor running on Ubuntu Linux."
Here are some more Processor articles from around the web:

Well this is interesting and, while not new, is news to me.
The upper-tier Haswell processors ushered DDR4 into the desktops for enthusiasts and servers, but DIMMs are quite expensive and incompatible with the DDR3 sticks that your organization might have been stocking up on. Despite the memory controller being placed on the processor, ASRock has a few motherboards which claim DDR3 support. ASRock, responding to Anandtech's inquiry, confirmed that this is not an error and Intel will launch three SKUs, one eight-core, one ten-core, and one twelve-core, with a DDR3-supporting memory controller.
The three models are:
|E5-2629 v3||E5-2649 v3||E5-2669 v3|
|Cores (Threads)||8 (16)||10 (20)||12 (24)|
|Clock Rate||2.4 GHz||2.3 GHz||2.3 Ghz|
The processors, themselves, might not be cheap or easily attainable, though. There are rumors that Intel will require customers purchase at least a minimum amount. It might not be worth buying these processors unless you have a significant server farm (or similar situation).

Tagged: apple, apple a8, SoC, iphone 6, iphone 6 plus
So one of the first benchmarks for Apple's A8 SoC has been published to Rightware, and it is not very different from its predecessor. The Apple A7 GPU of last year's iPhone 5S received a score of 20,253.80 on the Basemark X synthetic benchmark. The updated Apple A8 GPU, found on the iPhone 6, saw a 4.7% increase, to 21204.26, on the same test.
Again, this is a synthetic benchmark and not necessarily representative of real-world performance. To me, though, it wouldn't surprise me if the GPU is identical, and the increase corresponds mostly to the increase in CPU performance. That said, it still does not explain the lack of increase that we see, despite Apple's switch to TSMC's 20nm process. Perhaps it matters more in power consumption and non-gaming performance? That does not align well with their 20% faster CPU and 50% faster GPU claims...
Speaking of gaming performance, iOS 8 introduces the Metal API, which is Apple's response to Mantle, DirectX 12, and OpenGL Next Initiative. Maybe that boost will give Apple a pass for a generation? Perhaps we will see the two GPUs (A7 and A8) start to diverge in the Metal API? We shall see when more benchmarks and reviews get published.

Tagged: qualcomm, snapdragon 210, snapdragon, LTE, cheap tablet
The Snapdragon 210 was recently announced by Qualcomm to be an SoC for cheap, sub-$100 tablets and mobile phones. With it, the company aims to bring LTE connectivity to that market segment, including Dual SIM support. It will be manufactured on the 28nm process, with up to four ARM CPU cores and a Qualcomm Adreno 304 GPU.
According to Qualcomm, the SoC can decode 1080p video. It will also be able to manage cameras with up to 8 megapixels of resolution, including HDR, autofocus, auto white balance, and auto exposure. Let's be honest, you will not really get much more than that for a sub-$100 device.
The Snapdragon 210 has been given Quick Charge 2.0, normally reserved for the 400-line and up, refill the battery quickly when connected to a Quick Charge 2.0-supporting charger (ex: the Motorola Turbo Charger). Quick Charge 1.0 worked by optimizing how energy was delivered to the battery through a specification. Quick Charge 2.0 does the same, just with 60 watts of power (!!). For reference, the USB standard defines 2.5W, which is 5V at 0.5A, although the specification is regularly extended to 5 or 10 watts.
Devices featuring the Snapdragon 210 are expected for the first half of 2015.

Tagged: x86, VIA, centaur technologies
In early July, we reported on VIA's Centaur Technology division getting a new website. At the time, we anticipated that it would coincide with an announcement about Isaiah II, their rumored to be upcoming x86-based SoC (maybe even compatible with ARM, too).
Fifty-one days later, on August 31st, 2014, we came back at quarter-to-four EDT and let the website run its course, refreshing occasionally. 4 PM hit and... the counter stayed at 0 days, 0 hours, 0 minutes, and 0 seconds. Okay, I said. For about an hour, I refreshed occasionally because things could have happened on Labour Day weekend. I, then, came back late in the evening, and the day after. I next thought about it the week after, at which point the website was updated... with a timer that expires on September 30th, 2014.
So by the end of the month, we may find out what Centaur is trying to announce. I am a little less confident in the breadth of the announcement, given that the company waited for the timer to lapse before correcting their mistake. I would expect that if their big announcement, like a new SoC, were to hold up the launch, the company would have known ahead of time. At the moment, it sounds like a typical website redesign which got delayed.
I will hopefully be pleasantly surprised come the end of the month.

Tagged: xeon e5-2600 v3, xeon e5, Intel
So, to coincide with their E5-2600 v3 launch, Intel is discussing virtualized LANs and new, high-speed PCIe-based, networking adapters. Xeons are typically used in servers and their networking add-in boards will often shame what you see on a consumer machine. One of these boards supports up to two 40GbE connections, configurable to four 10GbE, for all the bandwidth.
The Intel XL710 is their new network controller, which I am told is being manufactured at 28nm. It is supposedly more power efficient, as well. In their example, a previous dual 10-gigabit controller will consume 5.2W of power while a single 40-gigabit will consume 3.3W. In terms of a network adapter, that is a significant reduction, which is very important in a data center due to the number of machines and the required air conditioning.
As for the virtualized networking part of the announcement, Intel is heavily promoting Software-defined networking (SDN). Intel mentioned two techniques to help increase usable bandwidth and decrease CPU utilization, which is important at 40 gigabits.
Receive Side Scaling disabled
The first is "generic segmentation offload" for VXLAN (VXLAN GSO) that allows the host of any given connection to chunk data more efficiently to send out over a virtual network.
Generic Segmentation Offload disabled
The second is TCP L4 Receive Side Scaling (RSS), which splits traffic between multiple receive queues (and can be managed by multiple CPU threads). I am not a network admin and I will not claim to know how existing platforms manage traffic at this level. Still, Intel seems to claim that this NIC and CPU platform will result in higher effective bandwidth and better multi-core CPU utilization (that I expect will lead to lower power consumption).
If it works as advertised, it could be a win for customers who buy into the Intel ecosystem.

I was originally intending to test this with benchmarks but, after a little while, I realized that Ivy Bridge was not supported. This graphics driver starts and ends with Haswell. While I cannot verify their claims, Intel advertises up to 30% more performance in some OpenCL tasks and a 10% increase in games like Batman: Arkham City and Sleeping Dogs. They even claim double performance out of League of Legends at 1366x768.
Intel is giving gamers a "free lunch".
The driver also tunes Conservative Morphological Anti-Aliasing (CMAA). They claim it looks better than MLAA and FXAA, "without performance impact" (their whitepaper from March showed a ~1-to-1.5 millisecond cost on Intel HD 5000). Intel recommends disabling it after exiting games to prevent it from blurring other applications, and they automatically disable it in Windows, Internet Explorer, Chrome, Firefox, and Windows 8.1 Photo.
Adaptive Rendering Control was also added in this driver. This limits redrawing identical frames by comparing the ones it does draw with previously drawn ones, and adjusts the frame rate accordingly. This is most useful for games like Angry Birds, Minesweeper, and Bejeweled LIVE. It is disabled when not on battery power, or when the driver is set to "Maximum Performance".

Tagged: Intel, core m, broadwell-y, Broadwell, 14nm
In a somewhat surprising fashion, Intel has decided to announce (again) the Core M processor family that will be shipping this fall and winter using the Broadwell-Y SoC. I was able to visit Portland and talk with the process technology and architecture teams back in early August so much of the news coming out today about the improvements of 14nm tri-gate transistors, the smaller package size of Broadwell-Y and the goals for thinner, fanless designs is going to be a repeat for frequent PC Perspective readers. (You can see that original story, Intel Core M Processor: Broadwell Architecture and 14nm Process Reveal.)
What is new information today are specifics on the clock speeds and SKU offerings.
|Base Freq||1.10 GHz||800 MHz||800 MHz|
|Max Single Core Turbo||2.6 GHz||2.0 GHz||2.0 GHz|
|Max Dual Core Turbo||2.6 GHz||2.0 GHz||2.0 GHz|
|Max Quad Core Turbo||N/A||N/A||N/A|
|Graphics||Intel HD Graphics 5300||Intel HD Graphics 5300||Intel HD Graphics 5300|
|Graphics Base/Max Freq||100/850 MHz||100/800 MHz||100/800 MHz|
|LPDDR3L Memory Speed||1600 MHz||1600 MHz||1600 MHz|
|TDP||4.5 watts||4.5 watts||4.5 watts|
Intel has planned three options, all with the same $281 pricing, though obviously based on volume and other deals with OEMs, these are likely to shift. The Core M 5Y70 is the highest performance part with a base clock speed of 1.10 GHz that can scale up to 2.6 GHz with one or both cores active. The other two parts launching today both feature 800 MHz base clocks and 2.0 GHz maximum Turbo speeds.
With that scaling information, and the wide range that the Intel HD Graphics 5300 can hit (100-800 MHz) Intel is doubling down on the benefits of fast and reliable Turbo Boost technology to give you high frequencies only when you need it most. This conserves power consumption the vast majority of time and allows Intel's partners to build fanless designs that are incredibly thin.
The 5Y10 and 5Y10a differ only in that the non-A variant has a configurable TDP down the 4.0 watts should the vendor opt for that.
Intel is also giving us a more detailed look at the Broadwell-Y PCH that includes a lot of I/O for such a small platform. Two channels of USB 3.0 can support four total ports and as many as four SATA 6G storage units can be integrated as well. These Y-SKUs look like they have 12 lanes of PCIe 2.0 available to them should a notebook vendor decide to use PCIe storage solutions (like M.2) rather than relying purely on SATA.
At least one partner has already announced a Core M product: the Lenovo ThinkPad Helix. It appears to be an amazing 11.6-in convertible tablet design. Without a doubt we'll encouter numerous other designs at the Intel Developer Forum that starts next Tuesday.

[H]ard|OCP reviewed Intel's brand new Extreme processor, the Haswell-E i7-5960X as weill as posting a large amount of Intel's launch slides detailing the new features present in this series of CPU. As you can see from the picture they used the same funky white ASUS motherboard which Ryan used in his review but chose a Koolance EX2-755 watercooler as opposed to the Corsair H100i which allowed them to hit 4.5GHz with 1.301v CPU core voltage, slightly lower than Ryan managed. In the end, while extremely impressed by the CPU they saw little benefits to gaming and recommend this CPU to those who spend most of their time encoding video, manipulating huge images and of course those who just want the best CPU on the planet.
"There are many members of the "1366 X58 Enthusiast Overclockers Club" that have been waiting with bated breath for Intel's launch of the new X99 Express Chipset and new family of Core i7 Haswell-E processors. All this new hardware comes bundled with brand new DDR4 RAM technology packing huge bandwidth as well."

The Tech Report took the new i7-5960X, Asus X99 Deluxe, 16 GB of Corsair Vengeance LPX DDR4, a Kingston HyperX SH103S3 240GB SSD and a XFX Radeon HD 7950 DD and set it loose on the test bench. The results were impressive to say the least, especially when they moved on from games to test productivity software where the Haswell architecture really shines. When they attempted to overclock the CPU they found a hard limit feeding the processor 1.3V and running 4.4GHz, any faster would cause some applications to BSoD. On the other hand that applied to all 8 cores and the difference in performance was striking.
Also make sure to read Ryan's review to get even mroe information on this long awaited chip.
"Haswell-E has arrived. With eight cores, 20MB of cache, and quad channels of DDR4 memory, it looks to be the fastest desktop CPU in history--and not by a little bit. We've tested the heck out of it and have a huge suite of comparisons going to back to the Pentium III 800. Just, you know, for context."

Tagged: rumour, leak, Intel, Haswell-E, 5960X, 5930K, 5820K
Take it with a grain of salt as always with leaks of these kind but you will be interested to know that videocardz.com has what might be some inside information on Haswell-E pricing and model numbers.
Intel i7 / X99 Haswell-E pricing:
- Intel Core i7 5960X 8C/16HT – 40-lane PCI-Express support (x16 + x16 + x8) — $999
- Intel Core i7 5930K 6C/12HT – 40-lane PCI-Express support (x16 + x16 + x8) — $583
- Intel Core i7 5820K 6C/12HT – 28-lane PCI-Express support (x16 + x8 + x4) —– $389
As you can see there is a big jump between the affordable i7-5820K and the more expensive 5930K. For those who know they will stick with a single GPU or two low to mid-range GPUs the 5820K should be enough for you but if you have any thoughts of upgrading or adding in a number of PCIe SSDs then you might want to seriously consider saving up for the 5930K. Current generation GPUs and SSDs are not fully utilizing PCIe 3.0 16x but that is not likely to remain true for long so if you wish for your system to have some longevity this is certainly something you should think long and hard about. Core counts are up while frequencies are down, the 8 core 5960X has a base clock of 3GHz, a full gigahertz slower than the 4790K but you can expect the monstrous 20MB cache and quad-channel DDR4-2133 to mitigate that somewhat. Also make sure to note that TDP, 140W is no laughing matter and will require some serious cooling.

Sorry for being about a month late to this news. Apparently, someone got their hands on an Intel Core i7-5960X and they wanted to see its eight cores. Removing the lid, they found that it was soldered directly onto the die with an epoxy, rather than coated with a thermal paste. While Haswell-E will still need to contend with the limitations of 22nm, and how difficult it becomes to exceed various clockspeed ceilings, the better ability to dump heat is always welcome.

While Devil's Canyon (Core i7 4970K) used better thermal paste, the method used with Haswell-E will be event better. I should note that Ivy Bridge-E, released last year, also contained a form of solder under its lid and its overclocking results were still limited. This is not an easy path to ultimate gigahertz. Even so, it is nice that Intel, at least on their enthusiast line, is spending that little bit extra to not introduce artificial barriers.

Tagged: X99, Intel, Haswell-E
Haswell-E, with its X99 chipset, are expected to launch soon. This will bring a new spread of processors and motherboards to the high-end, enthusiast market. These are the processors that fans of Intel should buy if they have money, want all the RAM, and have a bunch of PCIe expansion cards to install.
If you count the PCIe x1 slots, the table would refer to the first, third, fifth, and seventh slots.
To me, this is not too bad. You are able to use three GPUs with eight-lane bandwidth and stick a four-lane PCIe SSD on the last slot. Considering that each lane is PCIe 3.0, it is similar to having three PCIe 2.0 x16 slots. While two-way and three-way SLI is supported on all CPUs, four-way SLI is only allowed with processors that provide forty lanes of PCIe 3.0.
Gigabyte also provides three PCIe 2.0 x1 slots, which are not handled by the CPU and do not count against its available lanes.
Since I started to write up this news post, Gigabyte seems to have replaced their manual with a single, blank page. Thankfully, I was able to have it cached long enough to finish my thoughts. Some sites claim that the manual failed to mention the 8-8-8 configuration and suggested that configurations of three GPUs were impossible. That is not true; the manual refers to these situations, just not in the most clear of terms.
Haswell-E should launch soon, with most rumors pointing to the end of the month.

VIA subsidiary Centaur Technology is rumored to be launching a new x86 processor at the end of August based on the "Isaiah II" architecture. This upcoming chip is a 64-bit SoC aimed at the mobile and low power space. So far, the only known implementation is a quad core version clocked at up to 2.0 GHz with a 2MB L2 cache. Benchmarks of the quad core Isaiah II-based processor recently appeared online, and if the SiSoft Sandra results hold true VIA has very competitive chip on its hands that outperforms Intel's Bay Trail Z3770 and holds its own against AMD's Jaguar-based Athlon 5350.
The SiSoft Sandra results below show the alleged Isaiah II quad core handily outmaneuvering Intel's Bay Trail SoC and trading wins with AMD's Athlon 5350. All three SoCs are quad core parts with integrated graphics solutions. The benchmarks were run on slightly different configurations as they do not share a motherboard or chipset in common. In the case of the VIA chip, it was paired with a motherboard using the VIA VX11H chipset).

For comparison, The Atom Z3770 is a quad core clocked at 1.46 GHz (2.39 GHz max turbo) with 2MB L2 cache and Intel HD Graphics clocked at up to 667 MHz supporting up to 4GB of 1066 MHz memory. Bay Trail is manufactured on a 22nm process and has a 2W SDP (Scenario Design Power). Further, the AMD "Kabini" Athlon 5350 features four Jaguar CPU cores clocked at 2.05 GHz, a 128-core GCN GPU clocked at 600 MHz, 2MB L2 cache, and support for 1600 MHz memory. AMD's Kabini SoC is a 28nm chip with a 25W TDP (Thermal Design Power). VIA's new chip allegedly supports modern instruction sets, including AVX 2.0, putting it on par with the AMD and Intel options.

The SiSoft Sandra benchmarks spotted by TechPowerUp suggest that the Centaur Technology designed chip has potential. However, there are still several (important) unknowns at this point. Mainly, price and power usage. Also, the GPU VIA is using in the processor is still a mystery though Scott suspects an S3 GPU is possible through a partnership with HTC.
The chip does seem to be offering up competitive performance, but pricing and power efficiency will play a major role in whether or not VIA gets any design wins with system OEMs. If I had to guess, the VIA chip will sit somewhere between the Intel and AMD offerings with the inclusion of motherboard chipset pushing it towards AMD's higher TDP.
If VIA prices it correctly, we could see the company making a slight comeback in the x86 market with consumer facing devices (particularly Windows 8.1 tablets). VIA has traditionally been known as the low power x86 licensee, and the new expanding mobile market is the ideal place for such a chip. Its past endeavors have not been well received (mainly due to timing and volume production/availability issues of the Nano processors), but I hope that Centaur Technology and VIA are able to pull this one off as I had started to forget the company existed (heh).
