GeForce GTX 660 Based on GK104 Coming in July
The new GTX 660 will be based on GK104-400 silicon, this somehow proves most of our speculations, that NVIDIA is preparing their whole performance segment on a single GPU model. Previously released GTX 680 was based on GK104-400 as well, on the other hand GTX 670 is powered by GK104-325 variant.
As rumor goes further, it seems that NVIDIA is preparing two variants of GeForce GTX 660. A mid-range GPU would simply be called GeForce GTX 660, while card from performance model will have an additional Ti postfix. However if 660 Ti model is anywhere on a horizon, it’s obviously not very close.
Over the past few days, a new rumors came out on Chinese forums. According to them, GTX 660 will be based on a very short PCB, with comparable size to GTX 670 reference board. What is more, card will be 5% slower than Radeon HD 7950. Therefore, card would be slower than GeForce GTX 670 only by 13%. Source does not explain whether those bechmarks concern non-Ti or Ti model, but if those are true, there is just no sense in releasing any Ti model.
There is a lot of speculation about amount of SMX clusters coming with this card. Actual number is oscillating between 5 and 7. Every SMX cluster holds 192 CUDA cores, so these are very important for performance. Although benchmarks mentioned earlier in this post suggest that it may be equipped with 6 of them.
Pricing of both cards is still a mistery, but as Fudzilla predicts, that the first card could probably be priced between $199 and $249, while Ti version might be available for $299.
