NVIDIA’s new Maxwell based GeForce graphics cards are nearing launch and its time that we start seeing some major leaks. The first leak comes from Coolaler for GeForce GTX 870, revealing its specifications and a sneak peak of performance in 3DMark 11. The GPU-Z screenshot posted on the forums shows a slight increase in shaders compared to GeForce GTX 770 and a 4GB GDDR5 memory on the reference design. The specifications are not officially confirmed so please go through this news with a pinch of salt.
NVIDIA GeForce GTX 870 Specifications
NVIDIA GeForce GTX 870 features GM204 GPU equipped with 1664 shaders, 138 TMUs and 32 ROPs. The GPU comes with 4 GB GDDR5 memory spread across a 256-bit memory interface with 224.4 GB/s bandwidth. GeForce GTX 870 is clocked at 1051 MHz on core with GPU Boost 2.0 up to 1178 MHz and the memory is clocked at 1753 MHz effectively.
Since the GPU is not in the GPU-Z database so it was not recognized by the software. The software recognized it as “NVIDA D17U-20” which might indicate that it is an early engineering sample. The user also hid the AIB information (sub-vendor) which indicates that it belongs to one of NVIDIA’s AIB partners for GeForce GPUs. Lets see how the specifications compare to its predecessor:
|GeForce GTX 770||GeForce GTX 870||GeForce GTX 780|
|Process||28 nm||28 nm||28 nm|
|Memory Size||2 GB GDDR5||4 GB GDDR5||3 GB GDDR5|
|Core Clock||1046 MHz||1051 MHz||863 MHz|
|Boost Clock||1085 MHz||1178 MHz||900 MHz|
|Memory Clock||1750 MHz||1753 MHz||1500 MHz|
|Memory Bandwidth||224.2 GB/s||224.4 GB/s||288.6 GB/s|
NVIDIA GeForce GTX 870 Performance
Only 3DMark 11’s Performance and Extreme runs are not the performance indicators of a graphics card but something is better than nothing. GeForce GTX 870 should outperform GeForce GTX 770 as well GTX 780 and consume less power as well. The screenshots reveal that GTX 870 scores P11,919 in 3DMark 11 performance preset which is higher than its predecessor but not on par with GTX 780. The same can be said for its 3DMark 11 Extreme score of X4,625.
Reason being that GTX 780 features the flagship GK110 GPU with 2304 shaders while GTX 870 features GM204 GPU with 1664 shaders, so the performance gap is undeniable. NVIDIA introduced Kepler refresh, shipping the GTX 770 with same specifications as GTX 680 and introduced a new chip for its flagship GPU but it seems like this is not the case here. May be NVIDIA is targeting a low retail price in expense of performance and save the faster GPU for later.
Whatever the case maybe, GTX 870 can become a popular card if priced between $300-350 while the GTX 880 is speculated to be priced around $500.
