GeForce GTX 590 vs Radeon R9 M395X

Intro

The GeForce GTX 590 uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory works at a speed of 855 MHz on this specific model. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

Compare all of that to the Radeon R9 M395X, which features a clock frequency of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 590 is a better choice, by far. (explain)

GeForce GTX 590 58272 Mpixels/sec
Radeon R9 M395X 23136 Mpixels/sec
Difference: 35136 (152%)

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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 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 AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
