Nvidia GTX 1070 Has 25% of GP104 Die Cut Out – Lower Than Expected Performance
Nvidia has revealed its new GeForce GTX 1080 and GTX 1070, based on the next generation Pascal architecture. Since the release Nvidia has been giving information to the fans on the flagship GTX 1080. However, it has kept its mouth tightly closed when comes to GTX 1070 specs until now, as GTX 1070 specs have been revealed.
We were speculating that the GTX 1070 would be close to GTX 1080 in terms of performance, but it seems that GTX 1070`s performance is not so close to its elder sibling as we hoped it to be.
The specs for GTX 1070 have been revealed, according to which the 16nm GP104 silicon called the “GP104-200-A1” features 1920 CUDA cores with a max frequency of 1600 MHz. The TMU count is 120 while the 64 ROPs are retained. 8GB of VRAM remains standard though it is only GDDR5 and over a 256bit bus. This gives us a total of 6.5 TFLOPs of performance with 150W TDP.
Nvidia GTX 1070 Specifications:
- 16nm GP104 silicon “GP104-200-A1” GPU.
- 1920 CUDA cores.
- 15 out of 20 streaming multiprocessors enabled.
- 120 TMUs.
- 64 ROPs.
- 256-bit GDDR5 memory, 8 GB standard memory amount.
- Maximum GPU Boost frequency ~1600 MHz.
- 6.5 TFLOP/s single-precision floating point performance.
- 150W TDP, single 8-pin PCIe power connector.
- 3x DisplayPort 1.4, 1x HDMI 2.0b.
- 2-way SLI with SLI HB bridge support.
Not only this, Nvidia has cut out 25% of the GP104 die from GTX 1070, as this level of die reduction is the first time done by Nvidia for a GX04 graphics card, which usually has only 20% of the die cut from them.
However, GTX 970 is the only graphics card whose die was cut 20%, as GTX 660 and 560 are fair much better in terms of die. But, as long as GTX 1070 outperforms GTX 980 Ti in a lower price, this die cut does not really matter.
