GeForce GTX 1050 3GB vs Radeon HD 4790

Intro

Compare all of that to the Radeon HD 4790, which comes with a clock speed of 600 MHz and a GDDR5 memory speed of 800 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 4790 should perform a small bit faster than the GeForce GTX 1050 3GB in general. (explain)

Radeon HD 4790		102400 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 16384 (19%)

Texel Rate

The GeForce GTX 1050 3GB should be much (about 248%) better at texture filtering than the Radeon HD 4790. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 47616 (248%)

Pixel Rate

The GeForce GTX 1050 3GB should be quite a bit (more or less 248%) faster with regards to full screen anti-aliasing than the Radeon HD 4790, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 23808 (248%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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