GeForce GTS 250 1GB vs Radeon R7 250

Intro

The GeForce GTS 250 1GB features a GPU clock speed of 738 MHz, and the 1024 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon R7 250, which comes with a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

GeForce GTS 250 1GB 70400 MB/sec
Difference: 3200 (5%)

Texel Rate

The GeForce GTS 250 1GB should be much (more or less 97%) more effective at texture filtering than the Radeon R7 250. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 23232 (97%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTS 250 1GB is superior to the Radeon R7 250, and very much so. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 3808 (48%)

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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
