NVIDIA today launched a key performance-segment graphics card SKU, the GeForce GTX 670. This is NVIDIA’s third SKU based on its 28 nm GeForce Kepler 104 silicon, after GTX 680 and dual-GPU GTX 690. It is carved out of the GK104 silicon by disabling one streaming multiprocessor (SMX), resulting in a CUDA core count of 1344, and TMU count of 112 (vs. 1536 and 128 on the GTX 680, respectively). NVIDIA also toned down core clock speeds a tiny bit, with base core clock of 915 MHz, GPU Boost core clock of 980 MHz. The GeForce GTX 670 retains the memory and raster operations subsystems of the GTX 680, it is armed with 2 GB of GDDR5 memory across a 256-bit wide memory interface. The memory is clocked at 6.00 GHz, resulting in memory bandwidth of 192 GB/s, just as on GTX 680. It also packs 32 ROPs. The GeForce GTX 670 draws power from two 6-pin PCIe power connectors, its TDP is rated at 170W. Display outputs include two dual-link DVI and one each of HDMI and DisplayPort. The card retains 4-way SLI support, and support for 3D Vision Surround using a single card. NVIDIA suggests its MSRP to be US $399, but that could vary between partners and regions.
