Update - The Kaveri 2.0 APU details mentioned in this article are based around the mobile variants which will be clocked much lower at around 1.8 GHz hence the performance improvement compared to Richland looks to be a phenomenal increase.
There’s also some confusion surrounding the multi-threaded core architecture the APU would feature. It has been mentioned by AMD in their slides that clearly mentions four x86 Steamroller multi-threaded cores. It also shows 2 Decoders, 4 Pipelines per Decode and 2 L1 cache per core. So that equates to 8 threads on the Kaveri APU. We still don’t have any official word on this from AMD other than the slide but ill update you guys on this as soon as more information comes out.
About two weeks ago, AMD announced their next generation Kaveri APU featuring the SteamrollerB cores and GCN graphics at the AMD Developer Summit 2013. Today, we have some more details regarding the platform’s performance and features which we have been waiting to know for some time now.
AMD Kaveri APU Features 20% CPU and 30% GPU Performance Uplift Over Richland
We already know that AMD’s Steamroller core architecture would be incorporated inside the heart of the new APU. The Kaveri APU would feature upto four SteamrollerB cores with a total of 4 MB L2 cache. This would be backed up by the new temperature start turbo core technology (Turbo Core 3.0) which would provide the APU with boosted clock speeds depending on temperature and power levels. We really don’t know how this would work till AMD sends us a sample of the Kaveri to test but that isn’t going to happen until January 2014 so its best to wait for more information.
The part you want to learn is that the leaked slide mentions the SteamrollerB and GCN core actually provides a 20% CPU side performance uplift and 30% GPU side improvement over Richland APU. This is the same trend as was seen in AMD’s high-performance core roadmap which showed an annual 10-15% IPC improvement over past predecessors. Since Richland is based on the Piledriver core which itself is an improved Bulldozer variant, the new Kaveri APU’s 20% CPU-Side improvement was pretty much expected.
