Is the "surprise" an ARM core? :D
640 CCs for the GM107 seems reasonable to me, at least number-wise.

Thanks. Do you know the stock clocks of the 750 and 750 Ti?
Yeah, PedantOne wasn't the only one claiming a GK104 successor for Q1 2014.
If we trust SemiAccurate's articles and their tags, then from what I've gathered from the stuff that isn't restricted...
What's the difference? If it's a Kepler refresh wouldn't it be a Kepler part instead of a Maxwell part? (I don't seem to recall, say, GK104 being called a GF114 refresh, for instance.)
So is one a Maxwell part and another a Kepler part?
Also, when would the 880 and 870 be coming out?
So they're not 768 and 960 as rumors have claimed?
640/512 = 960/768 = 1.25 so those numbers would still imply 5 and 4 (or a multiple of such) SMXs, each with 128 (or a divisor of) CCs/SMX.
Rumors so far point to Maxwell-based GTX 750 Ti and 750 next month and nothing high-end until late this year at the earliest.
Well it doesn't have to be faster than the 780 Ti. Since that was released last month I guess that any Q1 2014 Maxwell would be slightly over 780-level performance at most.
Do you know the number of CCs, clock speeds, and memory bus width?
PedantOne, do you have any more details on this Maxwell chip?
I checked a couple of other, older and longer, threads and the "Thanks" button is not there. I also don't see the "Thanked [x] Times in [y] Posts" and stuff below user avatars either.
New comparison then, assuming 2880 CCs:
780 Ti (hypothetical)
K20X K6000 TITAN Prop. Half 225 W
CCs 2688 2880 2688 2880 2880 ...
I'm half-expecting the 780 Ti to have "only" a 225 W TDP.
Doesn't the TITAN have a 837 MHz core clock? Even so, we get 1029 MHz core [5.93 TFLOPS] and 239 W TDP [24.8 GFLOPS/W] if the increase is proportional (probably won't be the case) and 933 MHz core...
Also what about the DP rate? If the 780 Ti has 1/24 DP rate like the 780 then that would also be a downgrade relative to the Titan.
On the memory, maybe there could be 3 GB and 6 GB official...
2880 CCs and 7 Gbps memory? :up: :D
There was one rumor that mentioned the possibility of a 384-bit bus for Cayman.
Matt Skynner from AMD is saying BS?
From Forbes: "Exclusive Interview: AMD's Matt Skynner Talks New Radeon Cards, Next-Gen Consoles, 7990 Criticism."
He gives a bit of information about AMD's upcoming GPUs.
That's around...
I thought the realistic assumption for the past half year or so was that 20 nm GPUs (4770-like "test" chips excepted) would most likely not show up before mid/late 2014. It seemed to me that 20 nm...
Did you even read my post? No, you didn't.
Not for the K6000.

5196 peak SP GFLOPS (902 MHz), 1732 peak DP GFLOPS.
Doesn't Haswell already have 16 (DP) FLOPS per core per cycle?
(2 FP units) x ((256-bit FP unit) / (64-bit) = 4 FP operations) x 2 [FMA] = 16.
Interesting, the bandwidths between the two GPU-Z screenshots differ by 0.1 GB/s. Maybe the memory on the first one is clocked at 1753 MHz.
It was also a rumor for the GK110 last year, and more recently there was a rumor for the Titan LE having 2304 CCs.
