Four Processors Might Be Slated for AMD's AM1 Socket

Tagged: AM1, Kabini, amd

Chinese VR-Zone published claims that AMD will have up to four processors planned for AM1. This is the brand of socket designed for the upcoming Kabini APUs that we have discussed since the CES time frame. Three of the upcoming processors will be quad-core with one dual-core for variety. Regardless of core count, all four processors are listed at 25 watts (TDP).

Product Cores CPU
GPU
L2 TDP
A6-5350 Quad 2.05GHz HD 8400 2MB 25W
A4-5150 Quad 1.60GHz HD 8400 2MB 25W
E2-3850 Quad 1.30GHz HD 8280 2MB 25W
E1-2650 Dual 1.45GHz HD 8240 1MB 25W

Kabini pairs Jaguar cores, for x86-based serial processing, with a GCN-based graphics processor supporting DirectX 11.1. Users planning to purchase Kabini for use with Windows 8.1 should expect to miss out on some or all of the benefits associated with DirectX 11.2 (along with everyone on Windows 8 and earlier). Little of value would be lost, however.

These products are expected to be positioned against Bay Trail-D which powers Intel's Pentium and Celeron lines. The currently available products from Intel are classified at 10W TDP and around 2 GHz.

AMD is pushing lesser-clocked (and higher TDP) products based on Jaguar against Intel's Silvermont. I am not sure sure how the two architectures compare although I would expect the latter to win out clock-for-clock and watt-for-watt. Then again, cost and graphics performance could be significantly superior with AMD. Ultimately, it will be up to the overall benchmarks (and pricing) to see how they will actually stack up.

Is custom air cooling enough for the R9 290X?

Tagged: amd, asus, R9 290X DC2 OC, overclocking

[H]ard|OCP has had a chance to take the time to really see how well the R9 290X can overclock, as frequencies get lower as heat increases a quick gaming session is not enough to truly represent the performance of this new GPU.  The ASUS R9 290X DirectCU II OC offers a custom cooler which demonstrated the overclocking potential of this GPU on air cooling, or at least this specific GPU as we have seen solid evidence of performance variability with 28nm Hawaii GPUs.  You should read the full review to truly understand what they saw when overclocking but the good news is that once they found a sweet spot for fan speed and voltage the GPU remained at the frequency they chose.  Unfortunately at 1115MHz the overclock they managed was only 75MHz higher than the cards default speed and while that could beat a stock GTX 780 Ti, the NVIDIA product overclocked higher and proved the superior card.

"We will take the ASUS R9 290X DC2 OC custom AMD R9 290X based video card and for the first time see how well the 290X can overclock. We will also for the first time compare it to an overclocked GeForce GTX 780 Ti video card head-to-head and see who wins when overclocking is accounted for."

NVIDIA still holds the OpenGL crown on Linux; AMD is getting better though

Subject: General Tech | January 23, 2014 - 11:58 AM |
Tagged: opengl, linux, amd, nvidia

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.

AMD Introduces Two New Low Power Opteron 6300 Series Processors

Subject: Processors | January 22, 2014 - 08:12 PM |
Tagged: server, piledriver, opteron 6300, amd, 32nm

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.

Is AMD Showing Decent Recovery?

Subject: General Tech, Graphics Cards, Processors | January 22, 2014 - 06:41 PM |
Tagged: amd

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.

Linux kernel 3.13 and Radeon users rejoice

Subject: General Tech | January 20, 2014 - 09:31 AM |
Tagged: linux, 3.13, amd, radeon

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."

AMD Officially Launches R5, R7, R9 M200 Mobile GPU Series

Subject: General Tech | January 15, 2014 - 08:56 PM |
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.

AMD-Radeon-R9-M200-300W.png

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?).

AMD looking to take up the Mantle of huge scale games

Subject: General Tech | January 15, 2014 - 12:50 PM |
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!

nitrous-lead2.jpg

"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."
