The first GTX 660 (GK106) GPU-Z screenshot and 3DMark 11 benchmark results have been unveiled by ArabPcWorld.
The GPU-Z screenshot shows that the GTX 660 is based on the GK106 core architecture which is the fourth chip in the NVIDIA Kepler lineup. The GK106 would be used in the mid-range GPUs such as the GTX 660 and GTX 650 Ti.
The GTX 660 (GK106) consists of 960 Cores whereas the OEM version which is based on the GK104 core architecture features 1152 cores. The GTX 660 comes clocked at 980MHz core and 1033MHz Boost, a 2GB GDDR5 memory is clocked at 6008MHz though runs along the 192-bit interface.
Previously we had seen a die shot of the GK106-400-A1 core, it would measure around 221mm2 which is smaller than the GK104 core. You can see the physical diagram below:
We had also seen a leaked PCB shot earlier which suggested that the card would feature 2-Way SLI support and a single 6 Pin connector for power since the TDP is rated at 120-130W. Display outputs would consist of Dual DVI, HDMI and a Display port.
As far as performance is concerned, the GPU scores X2364 marks in 3DMark 11 whereas in another benchmark from Chinese forums, the GPU scored X2354 and P7000 Marks in same benchmark. For more benchmarks and details, head over to the article here.
The GTX 660 is said to launch sometime between 6th-12th September along with the GK107 based GTX 650 GPU. Both cards would cost $229 and $149 respectively.
