the overhead for running Windows is massive.

the resources lost to running the OS on a pc whilst gaming is MASSIVELY over stated.

2 or 3% at most.

For the OS, yes, for the ecosystem, it's massive. You have to support such a range of CPUs, for the cheapest Celeron to extreme $1000 units. Across the range of CPUs you need to support, some will be single core, some dual/tri/quad/hex/octo etc, some will have instruction sets that others lack, some will do single/dual core turbo while others will downclock when all cores are loaded. PC devs don't code for one set of hardware, everything is abstracted. On console, there is one target. You cannot put a percentage figure to how much that means.

I think you need to learn about memory bandwidth and how it affects resolution.
You've totally ignoring the point that ddr3 shared system memory will constrain
any performance gains at higher than 1680x1050 resolution, so no it won't be a big step up from Richland if on ddr3 thats my point.

Kaveri is about huma, hsa and cpu-gpu compute. Its the real fusion that they have talked about for years, If they want people to take their apus seriously they need to push the boundaries, SO that developers in software can then take their architecture and work with it. Why did Intel manage to catch up so qickly and exceed amd Llano and Trinity gpu performance, Why does haswell in the iris config feature edram?

I'm not ignoring anything bud, I think you're expecting to much. You mention Intel's Iris, look at how much Intel's Iris costs...

AMD are building an affordable all in one fusion of CPU / GPU. Doing a great job of it. Kaveri looks like good improvement over Richland. You have to be realistic, the target demo-graph of AMD's APU market is not someone willing to pay through the nose for DDR5 system memory or embedded EDram. Those types would just buy a dedicated GPU. Like I said earlier, it's easy for people to be negative. I am looking forward to Kaveri.

Intel's Iris Pro is in an odd slot, far too expensive for mainstream, not powerful enough for mid range (and still too expensive for mid range). It's little more than a practice run for Intel imo

e: Agree with the memory bandwidth issue, interesting to see how AMD have gotten around this...

JonSmith · 21 Sep 2013 at 20:54

Maybe they're going to incorporate a DDR4 memory controller on die? All AM3 CPUs for example are compatible with AM2+ socket boards.

Would be interesting to see how much affect on performance richland v kaveri that memory bandwidth had tho i.e. how much faster the other stats would be if at all with 15GB/s instead of 7.6.

If that was the speed with 1600mhz ram then some decent memory controllers like on haswell chips could make them twice as fast memory wise with 2666-2933mhz ram, even 2400mhz would be a step up from 1600

So exited for this. Can't wait.
Gonna replace my HAswell setup with the top CPU and my silent Streacom with the power efficient version

gpuerrilla · 23 Sep 2013 at 09:08

Are there any updates on this at the Hawaii launch or is that just for their GPU release?

Why would you replace a Haswell for a Kaveri?

We'll have to wait and see really, I'd be surprised to see anything though.

AMD Kaveri APU Could Have 832 Shaders

German site Planet3DNow reports that an upcoming Kaveri Spectre desktop APU could have as many as 832 shaders and 13 compute units. If this were to be the case it would mean the best Kaveri APU has much better GPU performance than expected – indeed the flagship was expected to have only 6 Compute units and 384 shaders like a HD 7730 has. With 13 compute units and 832 shaders the next AMD APU is more akin to somewhere in between a HD 7770 and HD 7790.

GP Processing:
AMD Kaveri APU R5 M200 @600 MHz (DDR3-1600) - 709.6 MPix/s
AMD Richland APU HD 8670D @844 MHz (DDR3-2133) - 239.3 MPix/s

Memory Bandwidth:
AMD Kaveri APU R5 M200 @600 MHz (DDR3-1600) - 15.0 GB/s
AMD Richland APU HD 8670D @844 MHz (DDR3-2133) – 12.4 GB/s

GP Cryptography:
AMD Kaveri APU R5 M200 @600 MHz (DDR3-1600) - 9.4 GB/s
AMD Richland APU HD 8670D @844 MHz (DDR3-2133) – 3.8 GB/s

If true the iGPU on this thing will be twice as powerful as the one on the A10-6800K

Assuming it's correct, it looks like the IMC is much improved if it can beat 2133MHz memory with 1600MHz. It'd be interesting to see what it'd be like with 2400MHz.

I wonder if Kaveri will have L3 cache? That's the main performance problem with the current APUs.

If they have L3 and 6 cores and a decent per clock per core performance I would switch to an FM2+ platform

teppic · 23 Sep 2013 at 16:32

I assume it'll still be 4 cores max? If the APUs have 6 or 8 cores and L3 cache, AM3+ would be retired.

Well, even if by some miracle they have Intel's performance: I.E same performance on 4 cores as the i5K I will wait for the SR AM3+ / AM4 6/8 core chip.

What I mean is if they release 8 core Kaveri APUs that have L3 cache, I can't see them continuing with two desktop platforms.

ah.. I see, seems logical, I think the intention is to eventually phase that platform out anyway.

There was talk of Kaveri having a 6 core variant.

The potential on Kaveri is literally through the roof.

It looks like they are gunning for IrisPro, perhaps, thanks to that its another red hot poker up AMD and its forced them to actually do something properly with what they have.
