AMD Publishes Mobile Kaveri Specifications
by Ryan Smith on May 26, 2014 12:26 PM EST
In an unexpected (and likely erroneous) move, AMD has published the specifications for their forthcoming mobile Kaveri APUs on their website this morning (scroll down and click on Model Comparisons and Product Specs, Update: they've since been pulled.).

Why doesn't every sku have true audio and trust Zone...MikeMurphy - Monday, May 26, 2014 - link
Because AMD hasn't migrated all of their chips to the GCN 1.1 architecture found in Bonaire and Hawaii that brings True Audio and trust zone support. It will happen soon enough.extide - Tuesday, May 27, 2014 - link
No, it has nothing to do with that. All of these chips (Mobile Kaveri) are GCN 1.1, they are just disabling some features on some chips like Intel does.Also, trust zone has nothing to do with GCN 1.1, Trust Zone is the ARM Cortex A5 core...
However, only having trust zone enabled on the lower end sku's is interesting.

Thinking about it some more, I bet there are 2 dies, the single-module (with the Cortex A5) and the dual-module, which probably doesn't have the Cortex A5 on it, and is probably why the higher end SKU's don't support Trust Zone. They are both going to be GCN 1.1 for sure, though, however the smaller die may not include the actual DSP's for TrueAudio, but the rest of the GPU part would still be GCN 1.1.BMNify - Monday, May 26, 2014 - link
the bag lady's that amd pull off the street can only sort through so much crap failed cores to re-classify them as these lower tear PR re-badged Soc , they will get to the next GCN 1.1 architecture crap pile soon enough so you can buy these cheeper failed core later...Khenglish - Monday, May 26, 2014 - link
Interesting that CPU clocks are higher than Richland, unlike on desktops. This should mean that we get a significant and badly needed CPU performance increase.TheinsanegamerN - Monday, May 26, 2014 - link
On top of that, kaveri on desktop keeps its base clock on the cpu when the gpu is under heavy load. if they can carry that behavior over to mobile (where the trinity a10 cpu runs at about 1.2GHz when the gpu is under load, hampering performance) we could see double the cpu performance under full load, which would be huge for AMD.Kevin G - Tuesday, May 27, 2014 - link
That would be ideal but that's also a very big 'if' considering the power budgets allocated here.TheinsanegamerN - Tuesday, May 27, 2014 - link
The a8-7600 did relatively well at 45 watt, so im hoping that amd can pull it off at 35 watt with lower clocks.jamescox - Thursday, May 29, 2014 - link
Seems to me that anything faster then a Core2 chip is sufficient for most applications. Most games seem to be GPU limited at actually useful resolutions. Having the fastest cpu is obviously great marketing, but for mobile use, performance per Watt is more important. Where is a Kaveri expected to fall?
