AMD A10-7850K And A8-7600: Kaveri Gives Us A Taste Of HSA
By

The benchmarks on this page employ workloads that we imagine are high on AMD’s list of tasks to accelerate through OpenCL, and ultimately to optimize for its HSA features. In fact, there’s already a beta version of HandBrake with OpenCL-based optimizations that offload cropping and down-scaling to the GPU.

At least in TotalCode Studio, however, encoding happens on x86 cores. This application leverage’s Rovi’s popular MainConcept codecs, which run well on Intel’s Core i5-4670K. The dual-core Core i3 and dual-module A10 and A8 APUs all turn in very similar results. Only the 45 W A8-6500T is completely blown away.

Switch over to the -7600 with a 45 W ceiling and you can take that 144-second finish time down to 98 seconds. We've already pointed this out several times, but AMD says it optimized Kaveri for that 45 W ceiling. In this case, those improvements cut 31% from the test's completion time.

Although we’re not using the OpenCL-accelerated beta of HandBrake, the stable version in our suite does explicitly leverage Kaveri’s support for FMA3/4, LZCNT, and BMI1. Then again, so does Richland’s Piledriver architecture.

Either way, A10-7850K manages a win against -6800K (for that matter, A8-7600 does too).

Dialed down to 45 W, the -7600 finishes in 213 seconds. Compared to the other 45 W part in our chart, AMD’s A8-6500T, that’s a phenomenal improvement. It’s just particularly sexy in a desktop environment.

Our LAME audio conversion test is single-threaded. It’ll allow each of these CPUs to spin up to their maximum Turbo Boost or Core frequency (unlike the per-cycle comparison we ran earlier, which sought to compare architectural efficiency at a fixed 4 GHz).

Intel’s Haswell design maintains its advantage. Richland, as it appears on the A10-6800K, hits higher clock rates and therefore is faster than Kaveri.

Again, curious as to how the 45 W version of A8-7600 would size up with its peak clock rate constrained to 3.3 GHz, I adjusted down the configurable TDP in ASRock’s firmware. The outcome was a finish time of 139 seconds—an impressive improvement over the A8-6500T standing in as our 45 W Richland-based APU.

The same story applies to iTunes, which is also single-threaded.

    While the gaming enthusiast may not have much here to get excited about, I think the real story here is the A8-7600. Especially at 45W, the numbers are quite impressive for this part.

    Of course, the other part of this story will be the adoption of HSA and Mantle. In this regard, I think AMD is playing its cards right. If you want to provide incentive for game developers to invest in developing for Mantle, that economic incentive is not going to come from providing a high-end part that tries to compete with high-end discrete GPUs. That economic incentive, and I believe it's huge, is in lowering the cost of entry to play your game.

    With the A8-7600, I believe AMD is providing a tremendous market opportunity and incentive if, with the combination of Kaveri plus embedded technologies (Mantle & True Audio), you can provide a playable gaming environment for the mass market. Admittedly, it may not be a "playable gaming environment" from an enthusiast standpoint, but as an entry point, it is quite good enough. It will be important for AMD to show that the release of Mantle for BF4 impacts performance for the Kaveri APUs in particular. More specifically, they will need to show that Mantle makes BF4 playable on a 7600. If they are successful in that regard, then I think they may really have something exciting here.

    I'm hoping AMD is successful in this, because it's obvious that the desktop CPU performance race has reached a point of diminishing returns. Kudus for AMD for potentially changing the game in the industry.

    All that said, they screwed up the pricing for the high-end. It needs to be $30 cheaper, and what is even the point of the 7700K? The 7850K at ~$145 and the 7600 where it is would have made much more sense if they want to incent adoption of this technology. The other point is they need to get motherboard manufacturers on-board with bringing more ITX FM2+ motherboards to market at different price points.

    A10-7850k is slower than A10-6800K ?? WTF.


    I got the opposite impression. Which graph are you looking at?

    Somethings with Diagram u provided at page 9 ~ Core i5 4760k @@Please fix that ~

    Yeah, almost all the diagrams refer to the 4760K.

    Given that AM3+ looks like it's done, it would have been nice to see a 6-core chip. Still, one of these may end up in my next laptop.

    Thank you for the article (especially the power consumption measurements), Chris. It is definitely an improvement over Richland but kind of boring (disappointingly expectable).

    I really like where AMD is going (HSA, GCN and TrueAudio).Too bad the manufacturing process of GlobalFoundries just can't match Intel's.

    Also, it would be interesting to see the new Bay Trail Pentium or Celeron CPUs (whichever is closer in performance) in the Efficiency graphs.

    I'm fairly sure that this is on TSMC's 28nm node. GlobalFoundries can't do that yet; this is on the same process used for AMD GPUs currently.

    28nm SHP from GlobalFoundries. AMD bought over $1 billion worth of wafers from them in december...

    I guess you have been reading the articles from a year ago about AMD still using TSMC despite promises of GlobalFoundries' new 28nm SHP process.

    I don't really believe into the whole HSA smoke-screen. By the time HSA-enabled apps take off, you will be ready to upgrade from your CPU again. The one terrible truth that stands out right now is that at current prices, the flagship Kaveri A10 doesn't make any sense whatsoever. Kaveri A8? Maybe. Richland A10-6790K? Perhaps. But the Kaveri A10 at $180 is a just a joke, specially after all that hype.

    CPUs are usually released at ridiculous prices, and come down over a month or two.

    There appears to a typo or at least a contradiction on the table (first page), which lists the A10-7700K with 512 shaders. The paragraph below then says it has 384 shaders.

    Basically at this point it is not worth the premium $50-60USD or so over Richland and Trinity. At $180, you can get an i5 3570k at some places like Microcenter. Another disappointing release from AMD.

    I'm extremely excited to see the results from more HSA compliant apps myself. Some of the benchmarks I have seen are beastly.I'm really starting to think that the APU is a superior approach. With x86 performance past a certain point CPUs with traditional cores will be relegated to specialised servers in the eyes of consumers. I mean how quickly do you want to open an excel spreadsheet or encode or decode music and video? 0.5s or 0.3s?

    @ vertexx ... finally a non troll or die hard Intel/AMD fan that is making sensible points...I used to be a gamer and spent thousands, being a die hard fan of one today's chip makers. Now, as a mainstream user that has to use their money towards real life applications (rather than FPS) like a house, family, children, eating, paying bills, etc... I tend now to look for a solution to spend the disposable income on a solution that is cheap but encompasses the ability to do a little of everything...Well done AMD... please keep the innovation coming, and competition alive too keep prices down for all to enjoy...

    Well if this is the future from AMD they are going to leave Intel alone in the high end gaming space.

    This measly increase in performance is just shoddy. Wonder what amazing story and hype AMD will put out for their next APU. I'm pretty much done with all this new advanced technology that's supposed to bring increased efficiency, performance, etc. etc. They've been doing this ever since they released their first APU. The next time AMD releases their next APU, I'll just jump straight into the benchmarks, see if that's any good.

    A8-7600 paired with R9-240 looks like a good deal. I belive this is a great Chance for AMD here if it sorts Crossfire performance things right Here lays the whole reason to buy APU instead of plain CPU.Why you have not commented about it in your final words when you thought about the alternatives?

    Yesterday there was an HD7770 so low that you could get that and an FX 6300 for like $5 more than what newegg is asking for the 7850k. You can get an HD 7750 in that general price range with an FX 6300 now. In desktop, APU's still hold no appeal to me at all. Mobile, they have promise for sure.
