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

Based on our earlier exploration of per-cycle performance, we know that AMD’s Steamroller architecture yields a nice speed-up in 3ds Max. And even though A10-6800K enjoys higher frequencies, the A10-7850K and A8-7600 (65 W) still turn in slightly better results.

The top Richland-based APU trades blows with Intel’s Core i3-4330, incidentally at the same price. AMD’s A8-7600 isn’t available yet, but once it is, we expect it’ll impress at around $120. We’d have a much harder time arguing in favor of the A10-7850K for $50 more when it’s only marginally faster.

Both 3ds Max and Blender might be considered heavy lifting for low-cost PCs. But that doesn’t stop Intel’s dual-core Core i3 from performing surprisingly well in our render project, besting AMD’s dual-module Kaveri APUs. The A10-7850K narrowly beats AMD’s A10-6800K, while the A8-7600 lands just behind Richland’s quickest incarnation.

Benchmarks make it pretty clear that it’s worth stepping up to Core i5 (or better) if you’re into more demanding content creation apps…at least for now. After all, this would seem to be the type of workload AMD is talking about when it extols the virtues of HSA.

A pure CPU test, Maxon’s Cinebench strictly gives us the difference between host processing performance. Steamroller, operating at its manufacturing process-limited peak and base clock rates, turns out to be slower than A10-6800K.

No surprise—the Haswell-based chips are faster than Piledriver and Steamroller in a single-threaded benchmark. It’s less expected to see Core i3 in front of the APUs, though.

The same thing happens in Sony’s Vegas Pro 12 as Intel’s CPUs take first and second place, while A10-6800K slides past the Kaveri-based APUs. This is an OpenCL-accelerated workload, so it’s strange that AMD’s latest doesn’t turn in stronger numbers. But when we turn off OpenCL and run the same benchmark, completion time nearly doubles. So hardware acceleration is definitely helping, just not as much as we would have thought given AMD's more modern graphics architecture.

    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.

    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.
