GeForce GTX 295 vs Radeon R9 M385X

Intro

The GeForce GTX 295 features a core clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also uses a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 28 ROPs.

Compare all that to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 295 should theoretically be much superior to the Radeon R9 M385X overall. (explain)

GeForce GTX 295 223776 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 127776 (133%)

Texel Rate

The GeForce GTX 295 should be much (more or less 50%) more effective at texture filtering than the Radeon R9 M385X. (explain)

GeForce GTX 295 92160 Mtexels/sec
Radeon R9 M385X 61600 Mtexels/sec
Difference: 30560 (50%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 295 is the winner, 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 megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
