There's no denying that the nVidia 8800 GT is a phenomenal, indeed award winning card, but we always suspected there was something more to come from G92, and so it was. Those of you not under NDA for the past weeks will be pleased to here that as rumoured the model up from the GT has launched today, under the confusing guise of the 8800 GTS 512MB.
I say confusing because despite sharing a name with the old GTS, in terms of specification the new model sits above both the 8800 GTX and even the 8800 Ultra. It shares the same 128 stream processors as those cards but has higher clock speeds, at 650Mhz, 1,625MHz and 2GHz (core, shader and memory respectively) versus the GTX's 575MHz, 1,350MHz and 1.8GHz and the Ultra's 312MHz, 1,500MHz and 2.16GHz.
However, while the two older cards run on a 384-bit memory interface backing onto 768MB of DDR3 RAM, the GTS 512 has, as the name suggests, 512MB of RAM which runs on a 256-bit bus. Going on the numbers then, we'd expect shader-intensive situations to favour the GTS 512 with memory heavy situations leaning towards the GTX/Ultra.
Although we haven't got a review of the card right now, our no-longer-sister site Bit-tech has evaluated performance so I don't actually need to speculate about real world performance, we'll be getting our own review up shortly for those of you who rightly want and need our opinions. From what we have seen though, and assuming the price is right, the new GTS will make a great stop gap between the new GT and the ages old GTX. Wallets at the ready people.
