Yesterday at the AMD APU13 developer conference, the company showed off the upcoming Kaveri APU running Battlefield 4 completely on the integrated graphics.  I was able to push the AMD guys along and get a little more personal demo to share with our readers.  The Kaveri APU had some of its details revealed this week:

  • Quad-core Steamroller x86
  • 512 Stream Processor GPU
  • 856 GFLOPS of theoretical performance
  • 3.7 GHz CPU clock speed, 720 MHz GPU clock speed

AMD wanted to be sure we pointed out in this video that the estimate clock speeds for FLOP performance may not be what the demo system was run at (likely a bit lower).  Also, the version of Battlefield 4 here is the standard retail version and with further improvements from the driver team as the upcoming Mantle API implementation will likely introduce even more performance for the APU.

The game was running at 1920x1080 with MOSTLY medium quality settings (lighting set to low) but the results still looked damn impressive and the frame rates were silky and smooth.  Considering this is running on a desktop with integrated processor graphics, the game play experience is simply unmatched.  

Memory in the system was running at 2133 MHz.

The second demo looks at the image decoding acceleration that AMD is going to enable with Kaveri APUs upon release with a driver.  Essentially, as the demonstration shows in the video, AMD is overwriting the integrated Windows JPG decompression algorithm with a new one that utilizes HSA to accelerate on both the x86 and SIMD (GPU) portions of the silicon.  For the most strenuous demo that used 22 MP images saw a 100% increase in performance compared to the Kaveri CPU cores alone.

ASUS Shows Off FM2+ Motherboards Compatible With AMD Kaveri APUs

Subject: Motherboards | July 28, 2013 - 07:40 PM |
Tagged: hUMA, Kaveri, hsa, fm2, asus, APU, A88X, A55, PCI-E 3.0, mATX

ASUS recently announced two new socket FM2+ motherboards that are compatible with AMD’s upcoming “Kaveri” Accelerated Processing Units (APUs). The new boards are the A88XMA and A55BM-A/USB3 and use the A88X and A55 AMD chipsets respectively. Pricing and availability have not yet been released, but the new boards confirm that users will need new motherboards in order to take advantage of AMD’s next generation APUs (though the new FM2+ boards are backwards compatible with the existing APUs, it will not work the other way around). Both motherboards should be available around the time of the Kaveri processor launch (2H 2013).

Both the ASUS A88XMA and A55BM-A/USB3 motherboards come in the mATX form factor. The boards both have FM2+ processor sockets and expansion slots including a single PCI-E 3.0 x16 slot, one PCI-E 2.0 x1 slot, and one legacy PCI slot. The support for PCI-E 3.0 is new for AMD motherboards, and the extra bandwidth may prove useful for as graphics cards get faster and AMD works on its hUMA and HSA architectures to create a layer of virtual memory that can be simultaneously addressed by CPUs and GPUs. There will still be latency to deal with over the PCI-E bus, but more data can be moved back and forth in the same amount of time.

The two ASUS FM2+ motherboards also share the same rear IO options, which include:

  • 2 x PS/2
  • 3 x Video outputs:
    • 1 x HDMI
    • 1 x DVI
    • 1 x VGA
  • 2 x USB 3.0
  • 2 x USB 2.0
  • 1 x Gigabit Ethernet
  • 3 x Analog audio jacks

The RJ45 jacks are backed by a Realtek 8111G Gigabit Ethernet controller and the audio jacks are handled by a Realtek ALC887-VD chipset. Finally, they also have UEFI BIOSes in common, but from there the two boards diverge in hardware capabilities.

The ASUS A88XMA is the higher-end of the two boards, and features a FM2+ socket, four DDR3 DIMM slots, and six SATA 3 6Gbps ports. It utilizes the AMD A88X chipset which is aimed at enthusiast platforms.

On the other hand, the A55BM-A/USB3 motherboard uses the cheaper A55 chipset. That motherboard features an FM2+ socket, two DDR3 DIMM slots, and six right angle SATA 2 3Gpbs ports. The A55Bm-A/USB3 should be significantly cheaper as a result of the A55 chipset and resulting hardware reductions. In most other respects, ASUS has managed to make the two baords remarkably similar, including aesthetics and basic board layout.

According to Bit-Tech, the two boards are are part of a larger family of boards with the new FM2+ sockets. As such, we should see additional ASUS boards that fill in the gaps between the two models closer to AMD's Kaveri launch. As noted above, ASUS has not provided official pricing or release date information yet.

AMD, HSA, LibreOffice and you

Need an excuse to give the 'boss' on why you need to buy a new AMD CPU or GPU?  Check out The Register for a reason custom made for you; accelerated LibreOffice performance which will help you when working on spreadsheets.  AMD will be working with the designers at the (slightly more successful) competitor to OpenOffice to allow the newest versions to be HSA compliant.  This is perhaps not a huge win as many people do not work with office documents which will greatly benefit from GPU acceleration but it does serve to show the acceptance the industry has to the HSA as LibreOffice joins applications such as Open C, C++ AMP, Java and Python in supporting HSA features.

"It is great to work on LibreOffice with The Document Foundation to expose the raw power of AMD GPUs and APUs, initially to spreadsheet users," said Manju Hegde, VP of heterogeneous solutions at AMD, in a statement."

AMD Planning APU13 Developer Summit In San Jose, California

Subject: General Tech | May 1, 2013 - 07:08 AM |
Tagged: hUMA, hsa, apu13, APU, amd, AFDS

AMD announced its third annual Developer Summit last week. Dubbed “APU13,” the upcoming summit is the AMD equivalent to NVIDIA’s GTC and is an annual event that brings together industry analysts, researchers, programmers, academics, and software/hardware companies pursuing heterogeneous computing technologies.

In previous years, the AMD Developer Summit has been the launchpad for C++ AMP and the HSA Foundation. This year’s Summit will continue that trend towards heterogeneous computing as well as look back over the year and provide updates on where the various HSA member companies are at as far as goals to move towards standards-based heterogenous computing.

In addition to keynote speeches from AMD and some of its partners, expect a great deal of presentations and workshops from researchers and programmers that are working on new programming models and hardware solutions to efficiently use CPU and GPU processors. More information on hUMA is one of the likely topics, for example. Discussion about upcoming hardware, process nodes, and products may also be on the table so far as it relates to the HSA theme. Considering the summit is called “APU13,” I also expect that AMD will reveal additional details on the company’s Kaveri APU as well as a look into its future product road map.

AMD is currently asking for presentation proposals from researchers in a number of HSA and technology-related fields including heterogeneous computing, cloud computing, web technologies, programming languages, gaming and graphics technologies, and software security. The lineup of presenters for the summit is still being worked out, and proposal papers will be accepted until May 10th with the winners being notified over the summer.

In all, AMD’s APU13 should be an exciting and intellectual event. Last year’s AMD Fusion Developer Summit (AFDS) was an interesting and fun event to cover, and I hope that APU13 will keep up the same momentum and interest in heterogeneous computing that AFDS started.

hUMA has come with a weapon to slay the memory latency dragon

Tagged: Steamroller, piledriver, Kaveri, Kabini, hUMA, hsa, GCN, bulldozer, APU, amd

AMD may have united GPU and CPU into the APU but one hurdle had remained until now, the the non-uniformity of memory access between the two processors.  Today we learned about one of the first successful HAS projects called Heterogeneous Uniform Memory Access, aka hUMA, which will appear in the upcoming Kaveri chip family.   The use of this new technology will allow the on-die CPU and GPU to access the same memory pool, both physical and virtual and any data passed between the two processors will remain coherent.  As The Tech Report mentions in their overview hUMA will not provide as much of a benefit to discrete GPUs, while they will be able to share address space the widely differing clock speeds between GDDR5 and DDR3 prevent unification to the level of an APU.

Make sure to read Josh's take as well so you can keep up with him on the Podcast.

huma_02.jpg

"At the Fusion Developer Summit last June, AMD CTO Mark Papermaster teased Kaveri, AMD's next-generation APU due later this year. Among other things, Papermaster revealed that Kaveri will be based on the Steamroller architecture and that it will be the first AMD APU with fully shared memory.

Last week, AMD shed some more light on Kaveri's uniform memory architecture, which now has a snazzy marketing name: heterogeneous uniform memory access, or hUMA for short."

heterogeneous Uniform Memory Access

 

Several years back we first heard AMD’s plans on creating a uniform memory architecture which will allow the CPU to share address spaces with the GPU.  The promise here is to create a very efficient architecture that will provide excellent performance in a mixed environment of serial and parallel programming loads.  When GPU computing came on the scene it was full of great promise.  The idea of a heavily parallel processing unit that will accelerate both integer and floating point workloads could be a potential gold mine in wide variety of applications.  Alas, the promise of the technology did not meet expectations when we have viewed the results so far.  There are many problems with combining serial and parallel workloads between CPUs and GPUs, and a lot of this has to do with very basic programming and the communication of data between two separate memory pools.

huma_01.jpg

CPUs and GPUs do not share common memory pools.  Instead of using pointers in programming to tell each individual unit where data is stored in memory, the current implementation of GPU computing requires the CPU to write the contents of that address to the standalone memory pool of the GPU.  This is time consuming and wastes cycles.  It also increases programming complexity to be able to adjust to such situations.  Typically only very advanced programmers with a lot of expertise in this subject could program effective operations to take these limitations into consideration.  The lack of unified memory between CPU and GPU has hindered the adoption of the technology for a lot of applications which could potentially use the massively parallel processing capabilities of a GPU.

The idea for GPU compute has been around for a long time (comparatively).  I still remember getting very excited about the idea of using a high end video card along with a card like the old GeForce 6600 GT to be a coprocessor which would handle heavy math operations and PhysX.  That particular plan never quite came to fruition, but the idea was planted years before the actual introduction of modern DX9/10/11 hardware.  It seems as if this step with hUMA could actually provide a great amount of impetus to implement a wide range of applications which can actively utilize the GPU portion of an APU.

Qualcomm Joins HSA Foundation to Further Heterogeneous Computing Standards

Subject: General Tech | October 4, 2012 - 05:28 PM |
Tagged: qualcomm, hsa, APU, amd, AFDS

The HSA Foundation announced today that Qualcomm would be joining as its newest Founder-level member. The mobile ARM System on a Chip company joins AMD, ARM, Imagination Technologies (the company who licenses out PowerVR graphics), MediaTek, Samsung, and Texas Instruments. Reportedly, the HSA Foundation has doubled its total members since its inception in June where it was announced at the AMD Fusion Developer Summit (AFDS 2012).

500px-QualcommLogo.png

Senior Vice President of Engineering at Qualcomm Jim Thompson has stated that the company is joining the HSA Foundation in an effort to standardize aspects of heterogenous computing. Those programming and hardware standards will then be incorporated into devices running future Snapdragon ARM processors.

HSA Foundation President Phil Rogers welcomed the mobile communications giant to the organization by stating the following.

“It’s great to see an innovative company like Qualcomm, which has revolutionized the wireless communications market, placing their support behind HSA.”

It is unclear from the press release where Qualcomm and the HSA Foundation will go from here, but it is promising to see additional companies lending their expertise to further heterogeneous computing standards. Here's hoping that the HSA Foundation is the opposite of the PC Gaming Alliance and actually gets things done to further the technology. After all, AMD is betting the company on APUs and could likely benefit from a big HSA programming standard push and the low power computing prowess of the ARM chip designers in its ranks.
