A new report of leaked benchmarks paints a very interesting picture of the upcoming AMD Carrizo mobile APU.

Announced as strictly mobile parts, Carrizo is based on the next generation Excavator core and features what AMD is calling one of their biggest ever jumps in efficiency. Now alleged leaked benchmarks are showing significant performance gains as well, with numbers that should elevate the IGP dominance of AMD's APUs.

"The A10 7850K scores around 270 Mpix/s while Intel’s HD5200 Iris Pro scores a more modest 200 Mpix/s. Carriso scores here over 600 Mpix/s which suggests that Carrizo is more than twice as fast as Kaveri and three times faster than Iris Pro. To put this into perspective this is what an R7 265 graphics card scores, a card that offers the same graphics performance inside the Playstation 4."
While the idea of desktop APUs with greatly improved graphics and higher efficency is tantalizing, AMD has made it clear that these will be mobile-only parts at launch. When asked by Anandtech, AMD had this to say about the possibility of a desktop variant:
“With regards to your specific question, we expect Carrizo will be seen in BGA form factor desktops designs from our OEM partners. The Carrizo project was focused on thermally constrained form factors, which is where you'll see the big differences in performance and other experiences that consumers value.”
The new mobile APU will be manufactured with the same 28nm process as Kaveri, with power consumption up to 35W for the Carrizo down to a maximum of 15W for the ultra-mobile Carrizo-L parts.

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".

The Chinese tech site, Evolife, acquired a few benchmarks for the Tegra K1. We do not know exactly where they got the system from, but we know that it has 4GB of RAM and 12 GB of storage. Of course, this is the version with four ARM Cortex-A15 cores (not the upcoming, 64-bit version based on Project Denver). On 3DMark Ice Storm Unlimited, it was capable of 25737 points, full system.

You might remember that our tests with an Intel Core i5-3317U (Ivy Bridge), back in September, achieved a score of 25630 on 3DMark Ice Storm. Of course, that was using the built-in Intel HD 4000 graphics, not a discrete solution, but it still kept up for gaming. This makes sense, though. Intel HD 4000 (GT2) graphics has a theoretical performance of 332.8 GFLOPs, while the Tegra K1 is rated at 364.8 GFLOPs. Earlier, we said that its theoretical performance is roughly on par with the GeForce 9600 GT, although the Tegra K1 supports newer APIs.
Of course, Intel has released better solutions with Haswell. Benchmarks show that Iris Pro is able to play Battlefield 4 on High settings, at 720p, with about 30FPS. The HD 4000 only gets about 12 FPS with the same configuration (and ~30 FPS on Low). This is not to compare Intel to NVIDIA's mobile part, but rather compare Tegra K1 to modern, mainstream laptops and desktops. It is getting fairly close, especially with the first wave of K1 tablets entering at the mid-$200 USD MSRP in China.
As a final note...
There was a time where Tim Sweeney, CEO of Epic Games, said that the difference between high-end and low-end PCs "is something like 100x". Scaling a single game between the two performance tiers would be next-to impossible. He noted that ten years earlier, that factor was more "10x".
Now, an original GeForce Titan is about 12x faster than the Tegra K1 and they support the same feature set. In other words, it is easier to develop a game for the PC and high-end tablet than it was to develop an PC game for high-end and low-end machines, back in 2008. PC Gaming is, once again, getting healthier.

Tagged: Intel, NAB, NAB 14, iris pro, Adobe, premiere pro, Adobe CC
When Adobe started to GPU-accelerate their applications beyond OpenGL, it started with NVIDIA and its CUDA platform. After some period of time, they started to integrate OpenCL support and bring AMD into the fold. At first, it was limited to a couple of Apple laptops but has since expanded to include several GPUs on both OSX and Windows. Since then, Adobe switched to a subscription-based release system and has published updates on a more rapid schedule. The next update of Adobe Premiere Pro CC will bring OpenCL to Intel Iris Pro iGPUs.
Of course, they specifically mentioned Adobe Premiere Pro CC which suggests that Photoshop CC users might be coming later. The press release does suggest that the update will affect both Mac and Windows versions of Adobe Premiere Pro CC, however, so at least platforms will not be divided. Well, that is, if you find a Windows machine with Iris Pro graphics. They do exist...
A release date has not been announced for this software upgrade.

We have great news for you this evening! The demise of the LGA processor socket for Intel desktop users has been great exaggerated. During a press session at GDC we learned that not only will Intel be offering LGA based processors for Broadwell upon its release (which we did not get more details on) but that there will be an unlocked SKU with Iris Pro graphics implemented.
Iris Pro, in its current version, is a high performance version of Intel's processor graphics that includes 128MB of embedded DRAM (eDRAM). When we first heard that Iris Pro was not coming to the desktop market with an LGA1150 SKU we were confused and bitter but it seems that Intel was listening to feedback. Broadwell will bring with it the first socketed version of Iris Pro graphics!
It's also nice to know that the rumors surrounding Intel's removal of the socket option for DIY builders was incorrect or possibly diverted due to the reaction. The enthusiast lives on!!
UPDATE: Intel has just confirmed that the upcoming socketed Broadwell CPUs will be compatible with 9-series motherboards that will be released later this spring. This should offer a nice upgrade path for users going into 2015.

Gigabyte is showing off a new small form factor BRIX-series PC at CES this week. This new BRIX Pro computer offers up desktop-level performance in a tiny form factor (approximately 4.2” width x 4.5” length x 2” height).
The BRIX Pro is available as a DIY kit that comes with a black or red chassis, choice of either Intel i7 4770R or Intel i5 4570R processor, mini PCI-E Wi-Fi card, and power adapter/cable. In addition to the CPU performance offered by the Haswell processor, the big news here is that the BRIX Pro ships with the processor-integrated Intel Iris Pro Graphics 5200. This GPU is the high-end model that comes with 64MB of eDRAM. Considering how rare the Iris Pro GPU with embedded DRAM has been in desktop PCs, having it available in the BRIX platform is good news for enthusiasts!
Gigabyte claims that the BRIX Pro is capable of 3D gaming and is compatible with content creation/production applications. Additionally, it can output 4K resolutions over HDMI thanks to the Iris Pro 5200 GPU (at least the desktop and video, most gaming is out at 4K).
From there, users can add their own memory, mSATA SSD, and 2.5” SATA III drive. There is a mPCIe slot as well, but it is used by the 802.11ac Wi-Fi + BT 4.0 card.

External IO on the BRIX Pro includes two USB 3.0 ports and a combination analog headphone/digital S/PDIF jack on the front. On the back of the SFF PC, users have two USB 3.0 ports, one Gigabit Ethernet jack, one Mini DisplayPort output, one HDMI video output, a DC power input, and a Kensington lock.
Gigabyte has not revealed pricing or availability information, but it should be coming out sooner rather than later in 2014. When it does become available, there will be two models: the GB-BXi7-4770R and the GB-BXi5-4570R.

The BRIX Pro looks to be a powerhouse for its size, though I am curious about the noise levels produced by the cooling fan needed to keep the high end processor cool. Overall though, the BRIX Pro looks to be a nice addition to the compact BRIX PC lineup, and I am looking forward to reviews of it. Stay tuned to PC Perspective for more information as it becomes available.

'Tis the season to be sharing and giving (unless you are Disney).
According to Phoronix, Intel has shipped (heh heh heh, "boatload") over 5,000 pages of documentation and technical specs for their Haswell iGPUs including the HD, Iris, and Iris Pro product lines. The intricacies of the 3D engine, GPGPU computation, and video acceleration are laid bare for the open source community. Video acceleration is something that is oft omit from the manuals of other companies.
Phoronix believes that Intel is, and has been, the best GPU vendor for open-source drivers. AMD obviously supports their open-source community but Intel edges them out on speed. The Radeon HD 7000 series is just beginning to mature, according to their metric, and Hawaii is far behind that. For NVIDIA, the Nouveau driver is still developed primarily by reverse-engineering. That said, documentation was released a few months ago.
Of course all of these comparisons are only considering the open-source drivers.
NVIDIA prides itself on their proprietary driver offering and AMD pretty much offers both up for the user to chose between. Phoronix claims that Intel employs over two-dozen open-source Linux graphics developers but, of course, that is their only graphics driver for Linux. That is not a bad thing, of course, because a launch open-source GPU driver is really identical to what they would launch for a proprietary driver just without slapping the wrists of anyone who tries to tweak it. It does make sense for Intel, however, because community support will certainly do nothing but help their adoption.
If you would like to check out the documentation, it is available at Intel's 01.org.

During their annual event today at the Yerba Buena Center for the Arts in San Francisco, Apple announced updates to their Mac lineups. After updating the MacBook Air with Haswell processors and teasing the new Mac Pro in June during WWDC, the rest of their offerings have seemed a little outdated.
Today, Apple started with a recap of the upgrades they have included in the next OS X release, Mavericks. Things like improved multi monitor support, and even more technical features like OpenCL support for integrated graphics and RAM compression were all talked about.
Perhaps the biggest news about OS X Mavericks is that it will be a free release to all users on 10.6 (Snow Leopard), 10.7 (Lion), or 10.8 (Mountain Lion), as long as their hardware is compatible. Mavericks is available today through the Mac App store.

The Intel HD Graphics are joined by Iris
Intel gets a bad wrap on the graphics front. Much of it is warranted but a lot of it is really just poor marketing about the technologies and features they implement and improve on. When AMD or NVIDIA update a driver or fix a bug or bring a new gaming feature to the table, they are sure that every single PC hardware based website knows about and thus, that as many PC gamers as possible know about it. The same cannot be said about Intel though - they are much more understated when it comes to trumpeting their own horn. Maybe that's because they are afraid of being called out on some aspects or that they have a little bit of performance envy compared to the discrete options on the market.
Today might be the start of something new from the company though - a bigger focus on the graphics technology in Intel processors. More than a month before the official unveiling of the Haswell processors publicly, Intel is opening up about SOME of the changes coming to the Haswell-based graphics products.
We first learned about the changes to Intel's Haswell graphics architecture way back in September of 2012 at the Intel Developer Forum. It was revealed then that the GT3 design would essentially double theoretical output over the currently existing GT2 design found in Ivy Bridge. GT2 will continue to exist (though slightly updated) on Haswell and only some versions of Haswell will actually see updates to the higher-performing GT3 options.
In 2009 Intel announced a drive to increase graphics performance generation to generation at an exceptional level. Not long after they released the Sandy Bridge CPU and the most significant performance increase in processor graphics ever. Ivy Bridge followed after with a nice increase in graphics capability but not nearly as dramatic as the SNB jump. Now, according to this graphic, the graphics capability of Haswell will be as much as 75x better than the chipset-based graphics from 2006. The real question is what variants of Haswell will have that performance level...
I should note right away that even though we are showing you general performance data on graphics, we still don't have all the details on what SKUs will have what features on the mobile and desktop lineups. Intel appears to be trying to give us as much information as possible without really giving us any information.
