Inno3D GeForce GTX 460 (768MB)
For this GeForce GTX 460 (768MB) graphics card we believe Inno3D has followed the reference PCB and cooler design as specified by Nvidia. The card measures 21cm long making it just a centimeter longer than the compact Radeon HD 5770 graphics card.
The GF100 die size measures 529mm2 whereas we measured the GF104 at about 390mm2 making it considerably smaller. Cooling the GPU is a radial heatsink that looks like something Zalman might have made.
This heatsink features a large copper base which is assisted by dual 6mm copper heatpipes. This heatsink is actively cooled by a 75mm fan which forces air over the heatsink where it exits the rear of the case.
Spec-wise the Inno3D board follows the reference speeds to the letter. Core frequency is set at the default of 675MHz and the GDDR5 memory runs at 3600MHz. The card packs 768MB using the 192-bit memory bus which provides a bandwidth of 86.4 GB/s which is roughly 10 GB/s more than the Radeon HD 5770.
Looking at the PCB it appears that Inno3D plans to use the same design for their 1024MB card as they simply need to add another two 128MB chips to reach that capacity. Around at the I/O panel the Inno3D GeForce GTX 460 (768MB) graphics card features dual DVI connectors and a DisplayPort connection.
