Alleged GeForce GTX 870 Sample Put Through 3DMark
A Coolaler.com community member claims to have scored a GeForce GTX 870 sample, ahead of its September 2014 launch. GPU-Z cannot correctly detect the GPU at this point. It is, however, programmed to pull out some details of unknown GPUs. It reads the card's name as "D17U-20" featuring a GPU name "13C2." The Device ID and BIOS fields are conveniently redacted, so we cannot say for sure if this is genuine.
The card's CUDA core count is 1,664. Given how streaming multiprocessors in "Maxwell" GPUs launched so far feature 128 cores, this particular chip features 13. Other features read out are 138 TMUs, 32 ROPs, and a 256-bit wide memory interface, holding 4 GB of GDDR5 memory. The sample features clock speeds of 1051 MHz core, 1178 MHz GPU Boost, and 1753 MHz (7012 MHz GDDR5 effective) memory, yielding 224 GB/s of memory bandwidth. The test-bed including a Core i7-4820K "Ivy Bridge-E" quad-core processor. The card was put through 3DMark 11, in its performance (P) and extreme (X) presets. It scored P11919 points in the performance preset, and X4625 in the extreme preset; which makes the card roughly as fast as a GeForce GTX 780. And these are pre-release drivers, and probably a pre-launch qualification sample altogether. Color us intrigued.

Sorted now but as such as you get pro Nv sites, I wouldn't use TT for any reference chart. Stick with TPU or Hardware Canucks. Always trust Canadians...
Note this post isn't strictly about the alleged 870 score, just the TT table posted by the quoted member.
Hardware Canucks is off my list until they renounce Bieber. Dion can stay, my wife has one of her albums. Adams too.
As for TT's benches, I always take them with a grain of salt these days - as was discussed in an earlier thread. If they can't even be bothered to update their outdated AIDA64 software, how much accuracy do you attribute to the rest of the benching process?

Full GM204 is either 14 or 15SMX. I dobut it will beat 780Ti, probably land between 780 and 780Ti by higher reso and higher AA values, 224gb/s is not enough..
Imo this GK204 is nothing special, only power consumption is a little better that's about it, just like by GK104.
ie Full GM200 chip is where its at for those with newer gpus.
