GeForce GTX 650 vs Radeon R7 250X 2GB

Intro

The GeForce GTX 650 features a GPU core clock speed of 1058 MHz, and the 1024 MB of GDDR5 memory runs at 1250 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon R7 250X 2GB, which comes with clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 64 Watts
Radeon R7 250X 2GB 95 Watts
Difference: 31 Watts (48%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 will be 11% quicker than the Radeon R7 250X 2GB in general, due to its greater data rate. (explain)

GeForce GTX 650 80000 MB/sec
Radeon R7 250X 2GB 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The Radeon R7 250X 2GB will be a little bit (approximately 18%) better at anisotropic filtering than the GeForce GTX 650. (explain)

Radeon R7 250X 2GB 40000 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 6144 (18%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 is a better choice, though only just barely. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R7 250X 2GB 16000 Mpixels/sec
Difference: 928 (6%)

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 transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
