GeForce GTX 1050 3GB vs Radeon HD 6990

Intro

The GeForce GTX 1050 3GB has a clock frequency of 1392 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 96-bit memory bus, and makes use of a 14 nm design. It features 768 SPUs, 48 Texture Address Units, and 24 ROPs.

Compare those specs to the Radeon HD 6990, which comes with a GPU core clock speed of 830 MHz, and 2048 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 TAUs, and 32 ROPs.

Pixel Rate

The Radeon HD 6990 should be much (about 59%) better at anti-aliasing than the GeForce GTX 1050 3GB, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 6990 53120 Mpixels/sec
GeForce GTX 1050 3GB 33408 Mpixels/sec
Difference: 19712 (59%)

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 information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of 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 better the texel rate, the better the 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 amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
