GeForce GTX 590 vs Radeon R9 295X2

Intro

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

Compare all that to the Radeon R9 295X2, which features GPU clock speed of 1018 MHz, and 4096 MB of GDDR5 memory set to run at 1250 MHz through a 512-bit bus. It also is comprised of 2816 SPUs, 176 TAUs, and 64 ROPs.

The Radeon R9 295X2 will be much (more or less 361%) more effective at AF than the GeForce GTX 590. (explain)

Radeon R9 295X2 358336 Mtexels/sec
GeForce GTX 590 77696 Mtexels/sec
Difference: 280640 (361%)

Pixel Rate

The Radeon R9 295X2 is quite a bit (about 124%) faster with regards to AA than the GeForce GTX 590, and also should be capable of handling higher screen resolutions better. (explain)

Radeon R9 295X2 130304 Mpixels/sec
GeForce GTX 590 58272 Mpixels/sec
Difference: 72032 (124%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
