NVIDIA is readying a new GPU to counter the Radeon HD 6950. Released earlier this month, reviews suggest that the HD 6950 managed to slip into a sweet-spot between GeForce GTX 470 and GeForce GTX 570/Radeon HD 5970, giving buyers an option for around $300. NVIDIA's counter to this is named GeForce GTX 560, it is based on the new 40 nm silicon. While specifications-wise, this GPU is identical to the GF104, it is redesigned to allow high-clock speeds with lower power draw, the same secret-sauce that went into making GF110 is applied here.
The GeForce GTX 560 features 384 CUDA cores, 32 ROPs, and a 256-bit wide memory interface that connects to 1 GB of memory. The new GPU has bolstered high GPU clock speeds, with 820 MHz core, 1640 MHz CUDA cores, and 4000 MHz (GDDR5 effective) memory, churning out 128 GB/s memory bandwidth. NVIDIA however, isn't in a hurry with its release, it has the GTX 560 slated for some time in January, 2011.
