GeForce 8800 GTS (G92) vs Radeon R7 250

Intro

The GeForce 8800 GTS (G92) has clock speeds of 650 MHz on the GPU, and 970 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare those specifications to the Radeon R7 250, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 11520 (19%)

Texel Rate

The GeForce 8800 GTS (G92) is quite a bit (approximately 73%) more effective at texture filtering than the Radeon R7 250. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 17600 (73%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is superior to the Radeon R7 250, and very much so. (explain)

GeForce 8800 GTS (G92) 10400 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 2400 (30%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
