Overclocked GeForce 7900 GT (PV-T71G-UCP7) from XFX
We removed the video card heatsink to take a look. It is all made of copper, as you can see in Figure 4.
As you may have notice in Figure 2, the heatsink doesn’t touch the memory chips, so no cooling solution is provided for them.
This video card has eight GDDR3 256-Mbit 1.4 ns chips from Samsung (K4J55232QG-BC14), making its 256 MB video memory (256 Mbits x 8 = 256 MB). These are the same chips used by NVIDIA’s reference model for GeForce 7900 GT. They can run officially up to 1.4 GHz and on this video card they are overclocked to 1.63 GHz. As a curiosity, the Radeon X1900 GT we reviewed used the same memory chips but with a different speed grade (1.2 ns, BC12).
The VIVO (video capture) function of this card is made through Phillips SAA7115HL chip, shown in Figure 6.
In Figure 7, you can see GeForce 7900 GT chip. As you can see, it is internally called G71-GT by NVIDIA.
This video card comes with two DVI-to-VGA adapters, two S-Video cables, one VIVO cable and one PCI Express auxiliary power adapter.
