GeForce GTX 465 benchmarks turn up

Although there have been plenty of rumours about Nvidia’s forthcoming mainstream Fermi-based GPUs, a more convincing slice of gossip has now just turned up in the form of supposed benchmarks of a GeForce GTX 465.

Chinese tech site Enet recently claimed it had got hold of a GeForce GTX 465, posting screenshots of benchmarks, photos of the chip and system information displayed in the Nvidia 197.75 driver Control Panel. Presumably, Nvidia wasn’t too happy about this, as the offending article has now been removed, but Expreview grabbed some screenshots from it before it went down.

If the screenshots from Nvidia’s driver Control Panel are to be believed, then the chip will come with 352 stream processors clocked at 1,215MHz.

Meanwhile, the GPU itself will have a clock speed of 607MHz, while the 1GB of memory is clocked at 1,603MHz (3,206MHz effective) and is addressed via a 256-bit memory interface.

The site also posted a photo of the chip, which shows that the GeForce GTX 465 has the model number GF100-030-A3, compared with the GF100-375-A3 number used on GTX 480 chips.

So how does it perform? To get a vague idea, Enet claims that it put the chip through its paces on a 2.67GHz Core i7 920 test bed with 6GB of RAM, using Windows 7 Ultimate 64-bit. The site then posted screenshots of the benchmark results from 3DMark Vantage, Unigine and Crysis Warhead.

All of the tests were run at 1,920 x 1,200 with 4x anti-aliasing. The card reportedly racked up an average frame rate of 18.8fps in Unigine, although the minimum dropped right down to 5.5fps. Meanwhile, Crysis Warhead in DirectX 10 mode saw an average of 19.95fps and a minimum of 13.87fps.

Finally, 3DMark Vantage produced a score of X5741, comprising a GPU score of 5488 and a CPU score of 45905, presumably thanks to Nvidia PhysX support.

Of course, it remains to be seen whether these results and screenshots are genuine, but they certainly look plausible. The GeForce GTX 465 is rumoured to be set for a release in June this year.
