It seems like only last Friday that we were poring over leaked PCB shots and making wild speculations about NVIDIA's mid-range GeForce GTS 450.
Well, now it looks like another morsel of information has slipped out, this time courtesy of Turkey's Donanim Haber. The source suggests that the GF106-based card will have a core clock of 789MHz, while the 1GB GDDR5 will supposedly run at 3,760MHz over a 128-bit bus. While the speeds are new, the details about the architecture and the memory line-up with what we'd heard previously about the card.
The only piece of the puzzle that remains now is the number of CUDA-cores that the GPU will have. Unfortunately, without this, clock speeds don't mean a lot and won't give us much of an idea of performance. Do bear in mind, though, that these clocks are quite a bit higher than the GTX 460's 675MHz and 3,600MHz for core and memory, respectively. Based on a completely unfounded guess, we'd put the GeForce GTS 450 as having 240 cores, given the higher core-clock.
According to the source, this card will launch later than the mid-August date that was put forward in earlier rumours. September 13 seems to be the new date, so we still have about six weeks to speculate about it. Until then, there's plenty of time for more details to slowly leak out.
