As might have been expected, the ASUS EN7950GX2 is an exact copy of the reference sample of the GeForce 7950 GX2 that we have in our labs. The single difference is the ASUS sticker on the top cooler’s fan:
We described the design of the GeForce 7950 GX2 in detail in our earlier review. In brief, the graphics card has two PCBs that are connected with four hex-headed poles and a two-section connector that is responsible for transferring power, MIO and PCI Express signals from one PCB to another.
Each PCB carries one G71 processor and 8 chips of GDDR3 memory from Samsung (K4J52324QC-BC14). Besides that, the bottom PCB is equipped with a PCI Express x16 slot, a MIO connector for connecting two such graphics cards into a quad-SLI system and a PCI Express switch. The top PCB in its turn carries DVI-I and TV-Out/HDTV outputs and an additional power connector.
The graphics cores and the memory chips of the ASUS EN7950GX2 are clocked at 500MHz and 600(1200)MHz, respectively, in full compliance with the official GeForce 7950 GX2 specification (some companies, for example XFX, offer pre-overclocked versions of the GeForce 7950 GX2 that provide increased performance). Although sixteen 512Mb chips of GDDR3 memory give you a total of 1GB, applications can only use 512 megabytes. This is the case with any of today’s multi-GPU consumer-class graphics subsystems.
