GeForce GTX 870 scores P11919 points in 3DMark11 We were told that GM204 cards indeed have higher clocks, so these numbers could be true. GeForce GTX 870 (allegedly) has a base clock of 1051 MHz and boost clock of 1178 MHz. NVIDIA would still use 7 GHz GDDR5 memory modules, but due to very short bus, bandwidth will not exceed 225 GB/s. Along with 1664 CUDAs, we have 4GB GDDR5 memory and 256b interface. Here is the link.īear in mind, it is rather easy to trick 3DMark to read anything you want. Core clock is not always read correctly by 3DMark (due to frequent profile changes), but memory clock is indeed 7GHz. Unfortunately our search did not bring any similar results.Īs you can see it does confirm that N17U does exist, in fact, it even confirmed it has 4GB frame buffer. If you look closely at the pictures, you will notice that the leaker didn’t uncheck the option to upload the scores to 3Dmark database. Something is telling me that NVIDIA would not remove 16 ROPs from full chip (880).

The full GM204 could have 15 SMMs, thus 48 ROPs. In GM107 there were 16 ROPs per one GPC (which has 5 SMMs). This could either mean that someone was manipulating with the picture, or GPU-Z does not fully support second generation Maxwell yet.

Each SMM has 8 TMUs, so the number of TMUs should actually be 104, not 138, 138 does not even divide by 8. The layout could’ve changed, but the basic principles should not.ġ664 CUDA cores mean there are 13 SMMs, since each SMM can hold 128 CUDAs. We are going to make a side-by-side comparison to GM107. If NVIDIA was to launch a new GPU, that would be the ID to use. The last entry is 13BB, which is yet unannounced Quadro based on GM107 chip. To start with, device ID 13C2 has not been used before. Our job is not to confirm that these leaked specs are legit, our job is to confirm they are not. We have to say, that numbers look poorly compared to full GK110 chip, but Maxwell may actually be that powerful. According to the leaker GeForce GTX 870 would sport 1664 CUDA cores (13 SMMs), 138 TMUs and 32 ROPs. GeForce GTX 8 CUDA cores?įirst of all, we have (supposedly) the number of CUDAs this card might have in its final form. Guys over at Coolaler managed to (allegedly) get their hands on the upcoming Maxwell GM204 graphics card.
