AMD Launches Three Kaveri APU SKUs in February 2014 – Feature Set For A10 and A8 APUs Detailed

Nope, AMD seem to be sticking with the Bulldozer-like architecture for now (2 modules each containing 2 integer and 1 floating point unit), as they're hoping parallel/floating point workloads will be sent to the GPU portion (where 80% of the power is) as soon as the software has been updated. This is part of the reason why it looks like an i3 in floating point tests.

Ah, so that explains why kaveri's cpu performance isn't matching AMD's FX CPUs in some tests as the FX still have a clock speed advantage.
I guess we really need to wait for software to catch up at this point.

The clock speed advantage of piledriver pretty much cancel out the efficiency improvements in steamroller. The difference between most FX and kaveri is that kaveri only has 2 modules, the same as an FX-4, whereas the FX-6 and -8 have 3 and 4 modules respectively.

Sweet, but still kinda sucks in terms of performance per pound.

AMD A10-6800K + 7770 = £200
AMD A10-7850K + R7 250 = £210

Probably £175 to £180 for the first and around £185 for the second if you shop around. OTH,if you use an Athlon II X4 760 it is still cheaper.

But its more interesting a mixed 512 shader and 384 shader config actually works.

I expect the price will fall to A10 6800K when the latter is sold out. Personally I think the A10 7850K is expensive too. The A8 7600 looks a better bet when it comes out for a small rig,and I expect the 384 shader R7 250 should be a better fit for the 384 shader A8 IGP.

6400k (£60) and 7750 low profile (£80)

Though I am starting to think that an X4 750k would have been a better cpu choice for the same money, doh!

Or even an X4 740,but at least single threaded performance won't be much different with an A6 6400K,although it is only a dual core.

It will be interesting to see how dual core Kaveri parts perform,as Kaveri improved multi-threaded performance mostly.

OTH,you have a Core i7 so I suppose it is not all bad.

Bandwidth starvation is hamstringing the 512 shader parts, that's why there's not much difference between it and 384 shader SKU's.
It needs more bandwidth to be able to stretch it's legs.

My little Gigabyte A88XN-WIFI is hardlocked at 2400mhz.
I've got 2800mhz ram sat here and cant make use of it.
I don't even think that's going to be enough to get much more out of the iGPU on my 7850k tbh.

Bought the board for an A8-7600, now if only we could buy them lol.

It seems it will do better in lower TDP brackets,especially with the IGP looking more efficient. Anyway the A8 7600 is not out yet!! :(

It seems that way,and it could be why there is a quad channel DDR3 memory controller onboard.

It will be interesting to see if it ever gets used.

i7 is my main (huge) rig, but I have also put together a portable ITX system for DJing and light gaming.

Kaveri's place on the market is difficult to understand when you consider Richland.

However.

Which isn't at all surprising for anyone who's seen kaveri promo material stating it's got a peak performance of 856 GFLOPS. The i5-4670S for comparison is 32*3.1 = 99 GFLOPS.

edit: 99 is double precision, not sure if 856 is SP or DP. It's probably 428 DP GFLOPS.

Are you going with the Kaveri or does that APU work OK for you?

The optimist in me was hoping for 7750 performance from the 7850k, but as that isn't the case, I opted to get a 7750 discrete instead.

Just realised that my USB monitor relies quite a bit on the cpu too (as it does the compression of the displaylink data to send over usb), so I need to upgrade the cpu.

The question is, do I go for a £90 6800k just for cpu duties, or wait for the A8-7600?

I can't be arsed swapping out the mobo, so I am stuck with FM2/FM2+
