This year’s AMD CES was actually more interesting than I was expecting. The details of the event were well known, as most Kaveri details have been revealed over the past few months. I was unsure what Lisa Su and the gang would go over, but it was actually more interesting than I was expecting.
This past year has been a big one for AMD. They seem to be doing a lot better than others expected them to, especially with all of the delayed product launches on the CPU side for quite a few years. This year saw the APU take a pretty prominent place in the industry with the launch of the latest generation consoles from Sony and Microsoft. AMD made inroads with mobile form factors with a variety of APUs. The HSA Foundation members have grown and HSA members ship two out of every three connected, smart devices. Apple also includes Firepro graphics cards with all of their new Mac Pros.
Kaveri is of course the big news here. AMD feels that this is the best APU yet. The combination of Steamroller CPU cores, GCN graphics compute cores, HSA, hUMA, HQ, TrueAudio, Mantle support, PCI-E 3.0 support, and a configurable TDP makes for a pretty compelling product. AMD has shuffled some nomenclature about by saying that Kaveri, at the top end, is comprised of 12 compute cores. These include 4 Steamroller cores and 8 GCN compute clusters. Each compute cluster matches the historical definition of a core, but of course it looks quite a bit different than a traditional x86 core.
We have gone over Kaveri pretty extensively in the past. The CPU is clocked at 3.7 GHz with a 4 GHz boost. The graphics portion clocks in at 720 MHz. It can support up to DDR-3 2400 MHz memory, which is really needed to extract as much performance out of this new APU. Benchmarks provided by AMD show this product to be a big jump from the previous Richland, and in these particular benchmarks are quite a bit faster than the competing i5 4670K.
Gaming performance is also improved. This APU can run most current applications at 1080P resolutions with low to medium quality settings. Older titles can be run at 1080P with Medium to High/Extreme settings. While this processor is rated at around 867 GFLOPS, which is around 110 GFLOPS greater than the previous top end Richland, it is more efficient at delivering that theoretical performance. It looks to be a significant improvement all around.
Software support is improving with applications from companies like Adobe, The Document Foundation, and Nuance. These cover HSA applications and in Nuance’s case, using the TrueAudio portion to clean up and accelerate voice recognition. TrueAudio is also being supported in five upcoming games. This is not a huge amount, but it is a decent start for this new technology.
Mantle is gaining a lot more momentum with support from 3 engines, 5 developers, and 20+ games in development. They showed off Battlefied 4 running Mantle on a Kaveri APU for the first time publicly. They mentioned that it ran 45% faster than Direct3D at the same quality levels on the same hardware. The display showed frame rates up in the low 50 fps area.
AMD is continuing to move forward on their low power offerings based on Beema and Mullins. Lisa claims that these parts are outperforming the Intel Baytrail offerings in both CPU performance and graphics. Unfortunately, she mentioned noting about the power consumption associated with these results. They showed off the Discovery tablet as well as a fully functional PC that was the size of a large cellphone.
They closed up the even by talking about the Surround House 2. This demo looks significantly better than the previous iteration we saw last year. This features something like a 34.2 speaker setup in a projected dome. It is much more complex than the House from last year, but the hardware running it all is rather common. A single high end Firepro card running on a single A10 7850K. The demo is also one of the first shows of a 360 degree gesture recognition setup.
AMD has come a long way since hitting rock bottom a few years back. They continue to claw their way back to relevance, and they hope that Kaveri will help them regain a foothold in the computing market. They are certainly doing well in the graphics market, but the introduction of Kaveri should help them gain more momentum in the CPU/APU market. We have yet to test Kaveri on our own, but initial results look promising. It is a better APU, but we just don’t know how much better so far.

The launch and subsequent availability of Kaveri is scheduled for the CES time frame. The APU unites Steamroller x86 cores with several Graphics Core Next (GCN) cores. The high-end offering, the A10-7850K, is capable of 856 GFLOPs of compute power (most of which is of course from the GPU).
Image/Leak Credit: Prohardver.hu
We now know about two SKUs: the A10-7850K and the A10-7700K. Both parts are quite similar except that the higher model is given a 200 MHz CPU bump, 3.8 GHz to 4.0 Ghz, and 33% more GPU units, 6 to 8.
But how does this compare? The original source (prohardver.hu) claims that Kaveri will achieve an average 28 FPS in Crysis 3 on low at 1680x1050; this is a 12% increase over Richland. It also achieved an average 53 FPS with Sleeping Dogs on Medium which is 26% more than Richland.
These are healthy increases over the previous generation but do not even account for HSA advantages. I am really curious what will happen if integrated graphics become accessible enough that game developers decide to target it for general compute applications. The reduction in latency (semi-wasted time bouncing memory between compute devices) might open this architecture to where it can really shine.
We will do our best to keep you up to date on this part especially when it launches at CES.

AMD will deliver its latest round of APUs (Kaveri) on January 14th. These processors, built on a 28nm process, will combine the Steamroller architecture on the CPU with HSA-compliant Graphics Core Next (GCN) cores on the GPU. Together they are expected to bring 856 GFLOPs of computational performance.
Thomas Ryan at SemiAccurate, however, remembers that AMD expected over a TeraFLOP.
Of course Kaveri has been a troubled chip for AMD. At this point Kaveri is over a year late and most of that delay is due to a series of internal issues at AMD rather than technical problems. But now with the knowledge that Kaveri missed AMD’s internal performance targets by about 20 percent it’s hard to be very positive about AMD’s next big-core APU.
The problem comes from a reduction in the clock rate AMD expected back in February 2012. Steamroller was expected to reach 4 GHz but that has been slightly reduced to 3.7 GHz; this is obviously a small impact from a compute standpoint (weakened by just under10 GFLOPs). The GPU, on the other hand, was cut from 900MHz down to 720 MHz; its performance was reduced by a whole
25% (Update: 20%. Accidentally divided by 720 instead of 900). Using AMD's formula for calculating FLOP performance, Kaveri's 856 GFLOP rating corresponds to an 18% reduction from the original 1050 GFLOP target.
But, personally, I am still positive about Kaveri.
The introduction of HSA features into mainstream x86 processors has begun. The ability to share memory between the CPU and the GPU could be a big deal, especially for tasks such as AI and physics. AI especially interests me (although I am by no means an expert) because it is a mixture of branching and parallel instructions. The HSA model could, potentially, operate on the data with whichever architecture makes sense. Currently, synchronizing CPU and GPU memory is very costly; you could easily spend most of your processing time budget waiting for memory transfers.
856 GFLOPs is a definite reduction from 1050 GFLOPs. Still, if Kaveri (and APUs going forward) can effectively nullify the latencies involved with GPGPU work, an Intel Ivy Bridge-E Core i7 4960X has an instruction throughput of ~160 GFLOPs.
And before you say it: Yes, I know, Ivy Bridge-E can be paired with fast discrete graphics. This combination is ideal for easily separated tasks such as when the CPU prepares a frame and then a GPU draws it; you get the best of both worlds if both can keep working.
But what if your workload is a horrific mish-mash of back-and-forth serial and parallel? That is where AMD might have an edge.

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.
More Details from Lisa Su
The executives at AMD like to break their own NDAs. Then again, they are the ones typically setting these NDA dates, so it isn’t a big deal. It is no secret that Kaveri has been in the pipeline for some time. We knew a lot of the basic details of the product, but there were certainly things that were missing. Lisu Su went up onstage and shared a few new details with us.
Kaveri will be made up of 4 “Steamroller” cores, which are enhanced versions of the previous Bulldozer/Trinity/Vishera families of products. Nearly everything in the processor is doubled. It now has dual decode, more cache, larger TLBs, and a host of other smaller features that all add up to greater single thread performance and better multi-threaded handling and performance. Integer performance will be improved, and the FPU/MMX/SSE unit now features 2 x 128 bit FMAC units which can “fuse” and support AVX 256.
However, there was no mention of the fabled 6 core Kaveri. At this time, it is unlikely that particular product will be launched anytime soon.
Retiring the Workhorses
There is an inevitable shift coming. Honestly, this has been quite obvious for some time, but it has just taken AMD a bit longer to get here than many have expected. Some years back we saw AMD release their new motto, “The Future is Fusion”. While many thought it somewhat interesting and trite, it actually foreshadowed the massive shift from monolithic CPU cores to their APUs. Right now AMD’s APUs are doing “ok” in desktops and are gaining traction in mobile applications. What most people do not realize is that AMD will be going all APU all the time in the very near future.
We can look over the past few years and see that AMD has been headed in this direction for some time, but they simply have not had all the materials in place to make this dramatic shift. To get a better understanding of where AMD is heading, how they plan to address multiple markets, and what kind of pressures they are under, we have to look at the two major non-APU markets that AMD is currently hanging onto by a thread. In some ways, timing has been against AMD, not to mention available process technologies.

As is usually the case, AMD will not comment on the accuracy of DigiTimes information but as we have seen in the past their roadmaps have been spot on. Over the next 8 months or so will see the arrival of the Hawaii GPU family and the entrance of Kaveri and Kabini chips, nothing new there but good to have independent confirmation. In the latter part of 2014 and 2015 things are a little more interesting as Beema will replace Kabini with an HSA compliant architecture and use a new socket called FS1B. In 2015 Beema will be replaced by a chip called Nolan and we will finally see the Excavator based Carrizo which are slated to have 45W and 65W versions.
You can expect to see FM1 and AM3 phased out of active production by the end of 2013, with AM3+ and FM2 being the two active sockets until FS1B arrives.
"AMD has recently updated its product roadmap and is set to release its Hawaii-based GPUs at the end of September, Kaveri-based APUs for the high-end segment and Kabini-based APUs for the entry-level segment in the first quarter of 2014, according to sources from the upstream supply chain."

The VR-Zone published an article back on the 5th of August which detailed the delay of Kaveri's release until 2014. The information they received put the initial production of the chips in December of this year, with them shipping some time in February of 2014 which they found quite disappointing as initially we were already supposed to be able to buy Kaveri if you go off of the initial announcements. AMD was quick to respond and stated that there is no change to the current release schedule as they had only stated that Kaveri would ship in 2013, not that it would be available for purchase by consumers. This is a frustrating situation for many enthusiast as the tweets and announcement at CES seemed to imply that we would be purchasing these chips already and is even worse for any system builders who had planned to be releasing systems based on Kaveri in time for the holiday season. Maybe gutting the PR department wasn't the best decision AMD has made recently?
"Call it a delay by any other name, but AMD has sent out an official statement saying that Kaveri will be available in 2014 after shipping in 2013.
As a recap: Lisa Su’s Computex 2013 keynote ended with an on-stage demo of Kaveri and an announcement that it would be shipping “towards the end of the year.”"
