GeForce GTX 295 vs Radeon R9 M385X

Intro

The GeForce GTX 295 features core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs along with 80 Texture Address Units and 28 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M385X, which features 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 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Radeon R9 M385X 61600 Mtexels/sec
Difference: 30560 (50%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 295 is a better choice, by far. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 14656 (83%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
