GeForce GTS 250 512MB vs Radeon R9 M385X

Intro

The GeForce GTS 250 512MB comes with clock speeds of 738 MHz on the GPU, and 1100 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 R9 M385X, which has a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M385X should in theory be quite a bit superior to the GeForce GTS 250 512MB in general. (explain)

Radeon R9 M385X 96000 MB/sec
GeForce GTS 250 512MB 70400 MB/sec
Difference: 25600 (36%)

Texel Rate

The Radeon R9 M385X should be quite a bit (approximately 30%) better at AF than the GeForce GTS 250 512MB. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTS 250 512MB 47232 Mtexels/sec
Difference: 14368 (30%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M385X is the winner, and very much so. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce GTS 250 512MB 11808 Mpixels/sec
Difference: 5792 (49%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel output 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 max fill rate.
