HCW does quite a few overclocking reviews for both Intel and AMD processors. This time, Carl Nelson got a hold of the high-end AMD A10-7850K and gave it a pretty healthy boost in frequencies. By the time he was done with it, the CPU was operating a whole gigahertz above stock simultaneous with a 300 MHz boost to its integrated graphics.

3DMark 2013 Fire Strike scores gained 27%.

One again, they break down tests along a suite of different games of varying engines and add some OpenCL tests to round things out. In real-world applications, the increase was not quite as dramatic as the one seen in 3DMark but still significant. This overclock allowed certain games to jump from 720p to playable at 1080p. Apparently this silicon is a decent little overclocker.

AMD Kaveri Platform Highlights
The latest AMD A10-7850K and A10-7700K APUs integrate an enhanced CPU core based on the ‘Steamroller’ architecture with a new and updated Radeon Graphics core. Supporting native 8 GT/s PCI Express gen 3.0 and DX11.1 graphics, these new AMD A-Series APUs also offer native support for 4K resolution displays on HDMI and DisplayPort.

Heterogeneous System Architecture (HSA) Maintained by the HSA Foundation, HSA is a system architecture that allows accelerators such as the graphics processor (GPU) to operate at the same processing level as the system's CPU, providing up to 50 per cent more GPU performance and up to 20 per cent more x86 instructions executed per cycle compared to previous implementations. The new AMD A10 series APUs are the first desktop PC processors to implement the performance advantages of HSA.

AMD TrueAudio Technology
The latest AMD A-Series APUs are also the first equipped with AMD TrueAudio Technology a new programmable audio pipeline that fundamentally redefines how digital audio is processed. By allowing the graphics cores to handle sound processing for spatialization, reverb, limiters and simultaneous voice processing, game developers have greater artistic freedom than ever before, allowing for a vastly more realistic and compelling audio experience.

AMD announces Garlic and Onion flavours on their first HSA chips

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.)

Process Decisions

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.

kv01.jpg

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.

AMD CES 2014 Presentation: Kaveri Goes Official

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.

kav01.jpg

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.

kav02.jpg

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.

kav03.jpg

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.

kav04.jpg

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.

kav05.jpg

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.

AMD A10-7850K and A10-7700K Kaveri Leaks Including Initial GPU Benchmarks

Subject: General Tech, Graphics Cards, Processors | December 3, 2013 - 04:12 AM |
Tagged: Kaveri, APU, amd

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).

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 Kaveri's Fast... But Less Than Expected.

Subject: General Tech, Processors | November 12, 2013 - 06:50 PM |
Tagged: Kaveri, apu13, amd

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.

AMD-Kaveri.jpg

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.
