14 DAY TRIAL // After just yesterday we brought you the very first image to allegedly picture the GTX 580, today it's time to report on yet another sighting of Nvidia's future flagship graphics card, the GTX 580 just being mentioned in one of the company's development drivers, along with the GTS 455 and GeForce 405.
The card was listed in the 32bit versions of the 261.00 development driver (the 64bit release strangely lacking this mention), suggesting the card is very close to getting launched.
Together with its flagship GTX 580, Nvidia's drives also lists other GeForce models, the GTS 455 being particularly interesting for mainstream users.
A GeForce 405 GPU is also listed, this most probably being a pretty low-end part, along with hardware ids for other five NVIDIA D13U dubbed cards, but not many details are know at this point.
Moving on to the GTX 580 however, this latest sighting doesn't comes with any hardware specifications, rumors stating Nvidia's card uses the GF110 GPU that should feature 512 stream processing units as well as 128 texturing units and a 384-bit or 512-bit wide memory bus.
These specs should lead to a 20% speed increase over Nvidia's current flagship, the GTX 480, that comes with “just” 480 stream processing units as well as 60 texturing units and a 384-bit memory interface.
Although nobody can confirm for sure the rumored GTX 580 specs, the infos that we have about the GTS 455 are even more sketchy, although I am pretty much sure these new cards will get a fully functional GF106 core, the GTS 450 actually coming with some of its memory controller/ROP pairs disabled, as explained in our GTS 450 review.
The fully-fledged GF106 core (as used in the GeForce GT 460M notebook graphics card) actually comes with 192bit memory bus, 384KB of L2 cache, and 24 ROPs, so these may as well end up as the specs of the unreleased GTS 455.
Although right now these is pretty much an educated guess, it shouldn't take long for these graphics cards to reach us, so stay tunned. (via TCMagazine)
