PCINLIFE has leaked two very important things – the alleged reference PCB of GTX 670 and its final performance in 3DMark benchmarks.
GeForce GTX 670 PCB is equipped with two 6-pin PEG connectors, 2GB of GDDR5 memory with 256-bit interface. Card is using 4 phase PWM section. The most interesting part are memory chips, we can clearly see empty slots, which basically means, we will see GeForce GTX 670 models with 4GB of memory soon.
As for GPU, its a cut-down version of GK104 chip with seven SMX clusters. It has 1344 CUDA cores with 112 TMUs and 32 ROPs.
PCINLIFE tested two variants of this card – reference and factory-overclocked Gigabyte GTX 670 (GV-N670OC-2GD2).
GeForce GTX 670 has slightly worse performance than GTX 680, but thanks to large overclocking community this would be only a matter of time when this card reaches performance of their bigger brother. Card will likely be released on March 7th, with a price tag of $349 for reference model and $399 for a model with non-reference design and factory overclocking.
