The GCN architecture that is behind Xbox One and Sony PS4 (among others) and the HSA (quite probably available as well in Xbox One and PS4) are coming now to notebook APUs.
OR how much could AMD reap the benefits (first time) of ATI acquisition in 2006?
OR how much the 28nm SHP (Super High Performance) process from Global Foundries will help AMD to compete?
OR will the next-gen Steamroller microarchitecture be sufficient to compete?
How “Kaveri” is Going to Change the World of Compute Capabilities [AMD YouTube channel, Jan 16, 2014]
The Four Technologies that make up AMD’s Kaveri APU [AMD YouTube channel, Jan 14, 2014]
In AMD Kaveri Review: A8-7600 and A10-7850K Tested [AnandTech, Jan 14, 2014] it was touted as:
The first major component launch of 2014 falls at the feet of AMD and the next iteration of its APU platform, Kaveri. Kaveri has been the aim for AMD for several years, it’s actually the whole reason the company bought ATI back in 2006. As a result many different prongs of AMD’s platform come together: HSA, hUMA, offloading compute, unifying GPU architectures, developing a software ecosystem around HSA and a scalable architecture. This is, on paper at least, a strong indicator of where the PC processor market is heading in the mainstream segment.
End of my insert
As with all previous AMD APU launches, we’re going to have to break this one down into three parts: CPU, the promise of HSA and GPU.
In a vacuum where all that’s available are other AMD parts, Kaveri and its Steamroller cores actually look pretty good. At identical frequencies there’s a healthy increase in IPC, and AMD has worked very hard to move its Bulldozer family down to a substantially lower TDP. While Trinity/Richland were happy shipping at 100W, Kaveri is clearly optimized for a much more modern TDP. Performance gains at lower TDPs (45/65W) are significant. In nearly all of our GPU tests, a 45W Kaveri ends up delivering very similar gaming performance to a 100W Richland. The mainstream desktop market has clearly moved to smaller form factors and it’s very important that AMD move there as well. Kaveri does just that.
In the broader sense however, Kaveri doesn’t really change the CPU story for AMD. Steamroller comes with a good increase in IPC, but without a corresponding increase in frequency AMD fails to move the single threaded CPU performance needle. To make matters worse, Intel’s dual-core Haswell parts are priced very aggressively and actually match Kaveri’s CPU clocks. With a substantial advantage in IPC and shipping at similar frequencies, a dual-core Core i3 Haswell will deliver much better CPU performance than even the fastest Kaveri at a lower price.
The reality is quite clear by now: AMD isn’t going to solve its CPU performance issues with anything from the Bulldozer family. What we need is a replacement architecture, one that I suspect we’ll get after Excavator concludes the line in 2015.
In the past AMD has argued that for the majority of users, the CPU performance it delivers today is good enough. While true, it’s a dangerous argument to make (one that eventually ends up with you recommending an iPad or Nexus 7). I have to applaud AMD’s PR this time around as no one tried to make the argument that CPU performance was somehow irrelevant. Although we tend to keep PR critique off of AnandTech, the fact of the matter is that for every previous APU launch AMD tried its best to convince the press that the problem wasn’t with its CPU performance but rather with how we benchmark. With Kaveri, the arguments more or less stopped. AMD has accepted its CPU performance is what it is and seems content to ride this one out. It’s a tough position to be in, but it’s really the only course of action until Bulldozer goes away.
It’s a shame that the CPU story is what it is, because Kaveri finally delivers on the promise of the ATI acquisition from 2006. AMD has finally put forth a truly integrated APU/SoC, treating both CPU and GPU as first class citizens and allowing developers to harness both processors, cooperatively, to work on solving difficult problems and enabling new experiences. In tests where both the CPU and GPU are used, Kaveri looks great as this is exactly the promise of HSA. The clock starts now. It’ll still be a matter of years before we see widespread adoption of heterogeneous programming and software, but we finally have the necessary hardware and priced at below $200.
Until then, outside of specific applications and GPU compute workloads, the killer app for Kaveri remains gaming. Here the story really isn’t very different than it was with Trinity and Richland. With Haswell Intel went soft on (socketed) desktop graphics, and Kaveri continues to prey on that weakness. If you are building an entry level desktop PC where gaming is a focus, there really isn’t a better option. I do wonder how AMD will address memory bandwidth requirements going forward. A dual-channel DDR3 memory interface works surprisingly well for Kaveri. We still see 10 – 30% GPU performance increases over Richland despite not having any increase in memory bandwidth. It’s clear that AMD will have to look at something more exotic going forward though.

End of my insert
For casual gaming, AMD is hitting the nail square on the head in its quest for 1080p gaming at 30 frames per second, albeit generally at lower quality settings. There are still a few titles that are starting to stretch the legs of a decent APU (Company of Heroes is practically brutal), but it all comes down to perspective. Let me introduce you to my Granddad. He’s an ex-aerospace engineer, and likes fiddling with stuff. He got onboard the ‘build-your-own’ PC train in about 2002 and stopped there – show him a processor more than a Pentium 4 and he’ll shrug it off as something new-fangled. My grandfather has one amazing geeky quality that shines through though – he has played and completed every Tomb Raider game on the PC he can get his hands on.
It all came to a head this holiday season when he was playing the latest Tomb Raider game. He was running the game on a Pentium D with an NVIDIA 7200GT graphics card. His reactions are not the sharpest, and he did not seem to mind running at sub-5 FPS at a 640×480 resolution. I can imagine many of our readers recoiling at the thought of playing a modern game at 480p with 5 FPS. In the true spirit of the season, I sent him a HD 6750, an identical model to the one in the review today. Despite some issues he had finding drivers (his Google-fu needs a refresher), he loves his new card and can now play reasonably well at 1280×1024 on his old monitor.
The point I am making with this heart-warming/wrenching family story is that the Kaveri APU is probably the ideal fit for what he needs. Strap him up with an A8-7600 and away he goes. It will be faster than anything he has used before, it will play his games as well as that new HD 6750, and when my grandmother wants to surf the web or edit some older images, she will not have to wait around for them to happen. It should all come in with a budget they would like as well.
