GeForce GTX 590 vs Radeon R9 M295X

Intro

The GeForce GTX 590 has a clock speed of 607 MHz and a GDDR5 memory speed of 855 MHz. It also features a 384-bit bus, and uses a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 ROPs.

Compare those specs to the Radeon R9 M295X, which comes with GPU clock speed of 750 MHz, and 4096 MB of GDDR5 RAM running at 1375 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 590 58272 Mpixels/sec
Radeon R9 M295X 24000 Mpixels/sec
Difference: 34272 (143%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
