GeForce 8800 GTS (G92) vs GeForce GTS 250 512MB

Intro

The GeForce 8800 GTS (G92) uses a 65 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM runs at a speed of 970 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTS 250 512MB, which makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory works at a speed of 1100 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Memory Bandwidth

The GeForce GTS 250 512MB, in theory, should be just a bit faster than the GeForce 8800 GTS (G92) in general. (explain)

GeForce GTS 250 512MB 70400 MB/sec
GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 8320 (13%)

Texel Rate

The GeForce GTS 250 512MB is just a bit (approximately 14%) more effective at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTS 250 512MB 47232 Mtexels/sec
GeForce 8800 GTS (G92) 41600 Mtexels/sec
Difference: 5632 (14%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTS 250 512MB is the winner, but it probably won't make a huge difference. (explain)

GeForce GTS 250 512MB 11808 Mpixels/sec
GeForce 8800 GTS (G92) 10400 Mpixels/sec
Difference: 1408 (14%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
