Specifications of the XFX 8800 GTX
The 8800 GTX has the following specifications:
Fabrication Process: 90 nm
Number of Transistors: 681 million
Core clock: 575 MHz
Shader Clock: 1350 MHz
Stream Processors: 128
Memory clock/ data rate: 900 MHz/1800
Memory Interface: 384 bits
Memory Bandwidth: 86.4 GB/s
ROPs: 24
Frame Buffer Size: 768 MB
Texture Fill Rate: 36.8 GT/s
RAMDACs: 400 MHz
Bus Technology: PCI Express
As you can see from this chart the 8800 GTX adds a third clock speed to the core and memory clocks we normally see. The new clock speed is for the stream processors and can be set and overclocked independently of the other clocks.
Benchmarking the XFX 8800 GTX
I used my normal test suite to benchmark the 8800 GTX consisting of 3DMark06, Quake 4, FEAR and a new addition to my test regime Battlefield 2142. The test system specifications for this review are as follows:
CPU: Intel X6800 Core 2 Extreme
Mainboard: abit AW9D-Max
RAM: Crucial PC2-8000 2 x 1GB
PSU: OCZ GameXStream 700W
HDD: 1x Raptor 74 GB, 1x 750 GB Seagate
3DMark06
I ran 3DMark06 with the default application settings and the default 8800 GTX settings. The results are as follows:
3D Marks: 10355
SM 2.0: 4796
HDR/SM3.0: 4870
CPU: 2288
To put that in perspective, the quad SLI system I tested only scored 8448 and the X1900 CrossFire system I reviewed only scored 7175. Granted those reviews were done on a system with a different CPU which would account for some of the performance differences.
