If you are a Linux user who prefers to use OpenGL graphics there is still a huge benefit to choosing NVIDIA over AMD. The tests Phoronix just completed show that the GTX680, 770 and 780 all perform significantly faster than the R9 290 with even the older GTX 550 Ti and 650 GPUs outperforming AMD's best in some benchmarks. That said AMD is making important improvements to their open source drivers as that is where they are lagging behind NVIDIA. The new RadeonSI Gallium3D for the HD7000 series shows significant performance improvements when paired with the new 3.13 kernel though still falling a bit behind the Catalyst driver they are now much closer to the performance of the proprietary driver. For older cards the performance increase is nowhere near as impressive but some certain benchmarks do show this Gallium3D driver to provide at least some improvements. Pity the Source engine isn't behaving properly during benchmarks which is why no tests were run on Valve's games but that should be solved in the near future.
"In new tests conducted last week with the latest AMD and NVIDIA binary graphics drivers, the high-end AMD GPUs still really aren't proving much competition to NVIDIA's Kepler graphics cards. Here's a new 12 graphics card comparison on Ubuntu."

AMD has updated its Opteron 6300 series lineup with two new processors with lower TDPs. Previously code-named "Warsaw," the Opteron 6370P and Opteron 6338P boast 99W TDPs and 12 and 16 Piledriver cores respectively.
The chips are similar to the existing Opteron 6300-series chips including the 32nm manufacturing process, dual die design, and the use of AMD's older Piledriver CPU cores instead of the latest Steamroller cores found in AMD's new Kaveri APUs. According to Supermicro, the lower 99W TDP parts offer up to 27% higher performance/watt compared to the existing "Abu-Dhabi" 6300 CPUs.
The Opteron 6338P is a twelve core processor clocked at 2.3 GHz base and 2.8 GHz turbo. The Opteron 6370P is a sixteen core part clocked at 2.0 GHz base and 2.5 GHz turbo. As such, the chips are two six and two eight-core silicon dies in one package respectively. The chips have 16MB of L3 cache and support the same instruction sets as the existing 6300 lineup including FMA3, BMI, and F16c. The new chips use AMD's Socket G34 which supports up to 4 sockets (dual die processors) per motherboard.
The new 99W 12-core 6338P and 16-core 6370P are available now for $377 and $598 respectively. The chips will be used in servers from Supermicro and Sugon, and purchasable directly from system integrators including Avnet and Penguin. AMD is aiming these chips at large data centers and cloud computing tasks. While the drop to 99W from the top-end series' 140W TDP does not seem like much, it makes a dramatic difference in the data center world where the electricity costs for racks of servers adds up rapidly.

AMD had a decent quarter and close to a profitable year as a whole. For the quarter ending on December 28th, the company managed $89 million dollars in profits. This accounts for interest payments on loans and everything else. The whole year averaged to a $103 million dollar gain in operating income although that still works out to a loss of $74 million (for the year) all things considered. That said, a quarterly gain of $89 million versus an annual loss of $74 million. One more quarter would forgive the whole year.
This is a hefty turn-around from their billion dollar operating loss of last year.
This gain was led by Graphics and Visual Solutions. While Computing Solutions revenue has declined, the graphics team has steadily increased in both revenue and profits. Graphics and Visual Solutions are in charge of graphics processors as well as revenue from the game console manufacturers. Even then, their processor division is floating just below profitability.
Probably the best news for AMD is that they plan the next four quarters to each be profitable. Hopefully this means that there are no foreseen hurdles in the middle of their marathon.

There is a new Linux kernel in the wild today and it comes with a lot of enhancements. IPTables has been replaced with the NFTables packet filtering and firewall engine, with backwards compatibility for those who actually forced IPTables to behave. There is a new scalable block layer to deal with the previously unreachable I/O that PCIe SSDs can reach and designed specifically for multi-core systems. There is much more but the update many are most excited about is the performance improvements to Radeons of the 7000 family and new models. The benchmarks that Phoronix posted are very impressive but that is only half the story, there are updates to HDMI audio and Radeon Dynamic Power Management is now enabled by default. Check out the full list of updates here.
"Linux kernel 3.13 has been released. This release includes nftables (the successor of iptables); a revamp of the block layer designed for high-performance SSDs; a framework to cap power consumption in Intel RAPL devices; improved squashfs performance; AMD Radeon power management enabled by default and automatic AMD Radeon GPU switching; improved NUMA and hugepage performance; TCP Fast Open enabled by default; support for NFC payments; support for the High-Availability Seamless Redundancy protocol; new drivers; and many other small improvements."

Tagged: r9 m290x, r7 m265, r5 m230, mobile gpu, GCN, amd
AMD recently took the wraps off of its latest mobile GPU series in the form of the R5 M200, R7 M200, and R9 M200 series. Currently, there is one GPU in each respective Rx M200 series including the AMD Radeon R5 M230, R7 M265, and R9 M290X. Do not get too excited, however. All of the new mobile GPUs are based on desktop versions of Volcanic Islands and not AMD's new Hawaii GPUs. As such, the Rx M200 series are essentially rebrands of the Radeon HD 8000M series (which was in turn OEM rebrands of the HD 7000M series) based around AMD's Graphics Core Next 1.0 architecture and specifically the Pitcairn GPU implementation.
All of the Rx M200 series support DirectX 11.2 Tier 1, up to 4GB GDDR5 memory, and at least 320 GCN shader cores. Informatin on the mid-range R7 M265 is scarce, but AMD has released information on the low and high end chips. Further, Computer Base has managed to put together specifications for the R5 M230 and R9 M290X. In short, the R5 M230 is a rebranded HD 8570 with higher clockspeeds and support for more memory while the R9 M290X is a rebranded HD 8970M with official support for DirectX 11.2 Tier 1 (the HD8970M technically supports it as well). A more detailed breakdown is as follows.
The R9 M290X features 1280 shaders clocked at 850MHz/900MHz (base/boost), 80 texture units, and 32 ROPs. OEMs can pair the GPU with up to 4GB of GDDR5 memory clocked at 1,200 MHz on a 256-bit bus.
The R5 M230 has 320 shaders clocked at 855MHz, 20 texture units, and 4 ROPs. This GPU can support up to 4GB of GDDR5 memory at 1,000MHz over a 64-bit bus.
Users will be able to get the new Rx M200 series graphics cards in mobile systems from Alienware, Clevo, Lenovo, and MSI. Other manufactures should pick up the new GPUs soon as well. The new series is not terribly exciting being nearly identical to the existing HD 8000M counterparts, but it does update the lineup to AMD's new naming and branding scheme. Notably, should AMD release a Hawaii-based mobile GPU, it has not left itself much room as far as naming goes (R9 M295X?).

Tagged: Star Swarm, Oxide Games, Nitrous, Mantle, gaming, amd
Without having seen Frostbite run in Mantle there is still some supposition as to the true effect of the new technology; will it increase the performance of high end PCs and allow lower end ones to do things they cannot under DirectX? Engadget has a video of a different Mantle based engine called Nitrous, displaying a demo called Star Swarm which can display thousands of objects simultaneously on screen. In the video they switch to DirectX to show you how much the demo slows down and what effects need to be disabled to be able to make it perform as it does under Mantle. If this translates to real game performance Mantle could totally change RTS and most other types of games by a huge margin. Let's hope it arrives soon now that Kaveri is out!
"Some RTS games set the limit at 50-70 units, while others can cope with as many as 500, but a new game engine called Nitrous takes things up a level: It uses AMD's Mantle programming tool to speed up communication between the CPU and GPU, allowing up to 5,000 AI- or physics-driven objects (i.e., not mindless clones or animations) to be displayed onscreen at one time."

Not only are the first Kaveri reviews arriving today, the A10-7850K is up for sale on both NewEgg and Amazon and the A10-7700K is available on NewEgg. This new part, at 45W competes favourably with the previous 100W Trinity APU in most tests and when Ryan boosted it to 65W it gained a little more. The Steamroller cores have been updated but not in a way that has a huge effect on CPU performance, on the other hand the 384 SIMD units composing the GPU portion of this chip are quite impressive, 1080p gaming of current generation titles is possible on this chip and we haven't seen it's big brother with 512 SIMD units yet. In the Tech Report's review you can see that BF4 is playable on this chip and this is not the Mantle version optimized for AMD's new architecture. It is also a pity that Thief was unavailable to see just what TrueAudio is capable of. Unfortunately this chip will not find its home in gamers dream machines, that is simply not where AMD is targeting its CPUs. However, for SFF systems that need to be energy efficient and where a discrete GPU is to big to fit Kaveri will usher in a new level of performance.
"AMD's next-generation APU packs in a ton of innovation, including updated "Steamroller" CPU cores, GCN graphics, and advanced HSA features. But is it enough to restore AMD's competitiveness in desktop processors?"

The AMD Kaveri Architecture
Kaveri: AMD’s New Flagship Processor
How big is Kaveri? We already know the die size of it, but what kind of impact will it have on the marketplace? Has AMD chosen the right path by focusing on power consumption and HSA? Starting out an article with three questions in a row is a questionable tactic for any writer, but these are the things that first come to mind when considering a product the likes of Kaveri. I am hoping we can answer a few of these questions by the end of this article, but alas it seems as though the market will have the final say as to how successful this new architecture is.
AMD has been pursuing the “Future is Fusion” line for several years, but it can be argued that Kaveri is truly the first “Fusion” product that completes the overall vision for where AMD wants to go. The previous several generations of APUs were initially not all that integrated in a functional sense, but the complexity and completeness of that integration has been improved upon with each iteration. Kaveri takes this integration to the next step, and one which fulfills the promise of a truly heterogeneous computing solution. While AMD has the hardware available, we have yet to see if the software companies are willing to leverage the compute power afforded by a robust and programmable graphics unit powered by AMD’s GCN architecture.
(Editor's Note: The following two pages were written by our own Josh Walrath, dicsussing the technology and architecture of AMD Kaveri. Testing and performance analysis by Ryan Shrout starts on page 3.)
The first step in understanding Kaveri is taking a look at the process technology that AMD is using for this particular product. Since AMD divested itself of their manufacturing arm, they have had to rely on GLOBALFOUNDRIES to produce nearly all of their current CPUs and APUs. Bulldozer, Piledriver, Llano, Trinity, and Richland based parts were all produced on GF’s 32 nm PD-SOI process. The lower power APUs such as Brazos and Kabini have been produced by TSMC on their 40 nm and 28 nm processes respectively.
Kaveri will take a slightly different approach here. It will be produced by GLOBALFOUNDRIES, but it will forego the SOI and utilize a bulk silicon process. 28 nm HKMG is very common around the industry, but few pure play foundries were willing to tailor their process to the direct needs of AMD and the Kaveri product. GF was able to do such a thing. APUs are a different kind of animal when it comes to fabrication, primarily because the two disparate units require different characteristics to perform at the highest efficiency. As such, compromises had to be made.
