NVIDIA sure took its time to launch the first graphics card using the latest 28nm technology, but when finally there it didn’t take long for more to follow. Besides GeForce GTX 690 that is soon to come, the company has another two cards coming, also based on the GK104 chip.

More details are surfacing on the coming cards from NVIDIA, and then we’re not just talking about the dual-chip $1000 card. The company has another two cards coming in the near future, and these will be priced lower than the current flagship GTX 680.

The chip inside GTX 680 is called GK104-400-A2, while GTX 670 will sport GK104-335-A2. The difference is that one SMX cluster has been deactivated, which results in a lower number of CUDA cores and texture units; 1344 and 112 respectively. It is still unclear whether the card will be called GTX 670 or get the suffix Ti, but the former sounds more likely with all the leaks in mind.

GTX 670 is due to launch in early May and should cost about $100 less than GTX 680. Performance should be right above GTX 580, and AMD Radeon HD 7950, which is the intended competition.

NVIDIA has another reduced version coming sporting the GK104 circuit, which will most likely be called GTX 660 Ti. if GTX 670 actually gets the suffix suffixet Ti, it is also possible that this card becomes GTX 670 instead. If we haven’t already confused you enough we can tell you that the chip is the same, but two SMX clusters have been deactivated and one of the memory channels.

The result of this is 1152 CUDA cores, 96 texture units, 192-bit memory bus and 24 raster units. The energy consumption should be below 150W, since the card will sport only one 6-pin PCI Express power connector. The frequencies are yet to be revealed, but the price should be in the 249 – 299 dollar area, which puts it against AMD Radeon HD 7850 och 7870. The launch date has not yet been set, but should be sometime in June.
