GeForce GTX 1050 3GB vs Radeon HD 7990

Intro

The GeForce GTX 1050 3GB uses a 14 nm design. nVidia has set the core frequency at 1392 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this model. It features 768 SPUs along with 48 Texture Address Units and 24 Rasterization Operator Units.

Compare that to the Radeon HD 7990, which makes use of a 28 nm design. AMD has clocked the core speed at 950 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

The Radeon HD 7990 is much (about 264%) better at AF than the GeForce GTX 1050 3GB. (explain)

Radeon HD 7990 243200 Mtexels/sec
GeForce GTX 1050 3GB 66816 Mtexels/sec
Difference: 176384 (264%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7990 is superior to the GeForce GTX 1050 3GB, by far. (explain)

Radeon HD 7990 60800 Mpixels/sec
GeForce GTX 1050 3GB 33408 Mpixels/sec
Difference: 27392 (82%)

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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
