GeForce 8800 GTS (G92) vs Radeon R7 250

Intro

The GeForce 8800 GTS (G92) features core clock speeds of 650 MHz on the GPU, and 970 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the Radeon R7 250, which features GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

The GeForce 8800 GTS (G92) will be a lot (about 73%) better at anisotropic 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

The GeForce 8800 GTS (G92) will be quite a bit (about 30%) faster with regards to full screen anti-aliasing than the Radeon R7 250, and also should be able to handle higher screen resolutions more effectively. (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 largest amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
