Gainward GeForce GTX 460 1024MB GS-GLH
Inno3D Geforce GTX 460 OC 1GB
Zotac ZT-40402-10P
Palit GeForce GTX 460 Sonic Platinum 1024MB GDDR5
MSI N460GTX Cyclone 1GD5/OC

1024MB GDDR5 SDRAM in 8 Samsung chips on the front side of the PCB. The memory chips are designed for the peak clock rate of 1250 (5000) MHz.

Leadtek WinFast GTX 460 768MB

768MB GDDR5 SDRAM in 6 Samsung chips on the front side of the PCB. The memory chips are designed for the peak clock rate of 1250 (5000) MHz.

Zotac ZT-40402-10P

As you can see, cards from Leadtek, Inno3D and Zotac copy the reference design. While Palit, Gainward MSI cards feature minor PCB layout improvements, especially related to power supply units.

Leadtek's 768MB card has the same PCB as the 1024MB counterparts, it just lacks two memory chips and narrower bus.

All graphics cards have 6-pin supplemental power connectors.

Maximum resolutions and frequencies:

  • 240 Hz maximum refresh rate
  • 2048 x 1536 x 32bit @ 85Hz Max -- analog interface
  • 2560 x 1600 @ 60Hz Max -- digital interface (Dual-Link DVI/HDMI)

As for the HDTV support, a review is available here.
