Nvidia Titan X vs Radeon HD 5970

Intro

The Nvidia Titan X comes with a core clock frequency of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also uses a 384-bit bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

Compare those specifications to the Radeon HD 5970, which features a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is made up of 1600 SPUs, 160 Texture Address Units, and 64 ROPs.

Radeon HD 5970 256000 MB/sec
Difference: 235520 (92%)

Texel Rate

The Nvidia Titan X will be much (more or less 37%) faster with regards to texture filtering than the Radeon HD 5970. (explain)

Nvidia Titan X 317408 Mtexels/sec
Radeon HD 5970 232000 Mtexels/sec
Difference: 85408 (37%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X 136032 Mpixels/sec
Radeon HD 5970 92800 Mpixels/sec
Difference: 43232 (47%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once 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 applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
