GeForce GTX 1050 3GB vs Radeon HD 4790

Intro

The GeForce GTX 1050 3GB has a GPU clock speed of 1392 MHz, and the 3072 MB of GDDR5 memory runs at 1750 MHz through a 96-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 24 ROPs.

Compare those specs to the Radeon HD 4790, which uses a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR5 memory runs at a speed of 800 MHz on this particular card. It features 640(128x5) SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 4790 should be a small bit faster than the GeForce GTX 1050 3GB overall. (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 quite a bit (approximately 248%) more effective 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

If running with high levels of AA is important to you, then the GeForce GTX 1050 3GB is the winner, and very much so. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 ability to get to the maximum fill rate.
