GeForce GTS 450 vs Radeon R7 M260X

Intro

The GeForce GTS 450 comes with a core clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Radeon R7 M260X, which has 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 theoretically be a little bit better than the GeForce GTS 450 in general. (explain)

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

Texel Rate

The GeForce GTS 450 is a lot (approximately 27%) better at texture filtering than the Radeon R7 M260X. (explain)

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

Pixel Rate

The GeForce GTS 450 will be much (about 90%) more effective at full screen anti-aliasing than the Radeon R7 M260X, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTS 450 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 moved across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
