The EVGA GeForce GTX 460 768MB SuperClocked
The EVGA GeForce GTX 460 SuperClocked is based on the reference NVIDIA GeForce GTX 460 video card design. That means it measures 8.25 inches in length
and the card stands at 4.376 inches tall. The card also uses a dual-slot cooling design for maximum cooling performance. EVGA also offers an external exhaust version of this card, that runs the GPU core hotter, but exhausts more of the hot air from the chassis. If you have a large case with good airflow then the design shown above is better, but if you have a smaller case or one with bad airflow you should purchase the EVGA model that better exhausts the hot air.
Flipping the EVGA GeForce GTX 460 video card video card over we
don't find too
many interesting things, but the card does have a back plate on it
behind the GPU that has the only four screws used to hold the GPU cooler
and shroud to the PCB. The reference design has eight other screw
holes on it, but none were being used.
Notice that along the top edge of the GeForce GTX 460 that one SLI
connector is placed on the card. This means that SLI and 3D Vision
Surround configurations are supported, but it will not be able to run
triple-SLI ever. We will be using an SLI bridge today to connect both of these cards together for dual-GPU performance numbers.
The NVIDIA GeForce GTX 460 video card requires a 450 Watt or greater
power supply with a minimum of 24 Amps on the +12 volt rail. It also requires that the power supply has two 6-pin PCI Express power connectors for proper connection.
It should be noted that the NVIDIA minimum system power requirement based is based on a PC configured with an Intel Core i7 3.2GHz CPU. If you are wanting to run
SLI we have been told that a 600 Watt or greater power supply is suggested by NVIDIA. NVIDIA refuses to give +12V requirements for SLI, which is strange since they suggest them for single card solutions.
The NVIDIA GeForce GTX 460 GDDR5 graphics card has a pair of
dual-link DVI-I outputs along with a mini-HDMI output header. The NVIDIA
GeForce GTX 460 features enhanced audio support over HDMI, this
includes bitstreaming support for both Dolby True HD and DTS-HD Master
Audio over HDMI. Notice that the cooling fan used on the GeForce GTX 460
extends past the plastic housing. We were told it was designed this
way to help pull in cooler air from outside the fan shroud. This is a
very interesting design and not one that we have seen on any video card reference designs in the past.
Here is a closer look at the center mounted 75mm fan that NVIDIA is
using to keep the GTX460 cool, but with little fan noise. Under the 75mm
cooling fan, NVIDIA is using a radial curved bifurcated fin heatsink
design on the GeForce GTX 460 video card. This design is not new to us,
as many years ago Intel began using this fin design on reference boxed
No review would be complete without a look under the hood of the
NVIDIA GeForce GTX 460 video card, so we removed the four screws that
hold the heat sink onto the GPU and off came the entire assembly. To
remove the GPU cooler from the shroud we just needed to remove four more
The GPU cooler used on the GeForce GTX 460 768MB and 1GB cards
doesn't look that big from the outside, but once you remove it from the
fan shroud you can see that it is rather large. The two copper heat
pipes also extend out to two separate stacks of aluminum cooling fins to
better dissipate the heat generated from the GF104 die.
The NVIDIA GeForce GTX 460 doesn't use the GF100 'Fermi' core like
on the GTX 480/470/465, but rather the new GF104 'Fermi' based
derivative. The core is covered with a heat spreader as is rather large
as you can see from the image above. The markings on the GF104 core
read 'GF104-300-KB-A1' on our NVIDIA GeForce GTX 460 768MB reference
