NVIDIA has outed its much-rumored GeForce GTX 460, a mid-range Fermi-based graphics card promising four times the performance of rivals, real-time PhysX and 3D support with a price tag of roughly $199. The company has focussed their efforts on DirectX 11 tessellation, with a quoted up to 4x improvement in performance over cards from other manufacturers.

Two cards are being announced, the GeForce GTX 460 768MB – expected to arrive from ASL, ASUS, Colorful, ECS, EVGA, Gainward, Galaxy, Gigabyte, Innovision 3D, Jetway, KFA2, Leadtek, MSI, Palit, Point of View, PNY, Sparkle and Zotac – together with the GeForce GTX 460 1GB, which will go on sale by July 26th 2010. Both have 336 CUDA cores and 56 texture units; the GTX 460 768MB has a 192-bit memory interface, while the GTX 460 1GB has a 256-bit memory interface.
The graphics clock runs at 675MHz while the processor clock runs at 1,350MHz; there’s also a 1,800 memory clock, NVIDIA SLI support, and 3D Vision/3D Vision Surround support. Standard ports include two Dual Link DVI and a mini HDMI (with an internal audio input for the latter, together with HDCP compliance), while maximum display resolution is 2,560 x 1,600. They’re both dual-slot cards with a PCI-e 2.0 x16 interface.
The NVIDIA GeForce GTX 460 768MB should be available from today, with an MRSP of $199; the GeForce GTX 460 1GB will be roughly $229 when it arrives later this month.
