GeForce GTS 450 1GB vs Radeon R7 M260X

Intro

The GeForce GTS 450 1GB comes with a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 RAM is set to run at 902 MHz through a 128-bit bus. It also is comprised of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R7 M260X, which features clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260X should in theory be a small bit better than the GeForce GTS 450 1GB overall. (explain)

Radeon R7 M260X 64000 MB/sec
GeForce GTS 450 1GB 57728 MB/sec
Difference: 6272 (11%)

Texel Rate

The GeForce GTS 450 1GB should be a lot (more or less 27%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

GeForce GTS 450 1GB 25056 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 5256 (27%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTS 450 1GB is the winner, and very much so. (explain)

GeForce GTS 450 1GB 12528 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 5928 (90%)

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 data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
