GeForce GTX 1050 vs Radeon HD 4790

Intro

The GeForce GTX 1050 has a core clock frequency of 1354 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon HD 4790, which features a core clock frequency of 600 MHz and a GDDR5 memory speed of 800 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 1050 should theoretically be a small bit better than the Radeon HD 4790 in general. (explain)

GeForce GTX 1050 114688 MB/sec
Radeon HD 4790 102400 MB/sec
Difference: 12288 (12%)

Texel Rate

The GeForce GTX 1050 will be much (more or less 182%) more effective at texture filtering than the Radeon HD 4790. (explain)

GeForce GTX 1050 54160 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 34960 (182%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 is a better choice, by far. (explain)

GeForce GTX 1050 43328 Mpixels/sec
Radeon HD 4790 9600 Mpixels/sec
Difference: 33728 (351%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
