GeForce GTX 1050 vs Radeon HD 4790

Intro

The GeForce GTX 1050 uses a 14 nm design. nVidia has clocked the core speed at 1354 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 32 ROPs.

Compare those specs 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 bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 1050, in theory, should be just a bit faster 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 is much (approximately 182%) more effective at AF than the Radeon HD 4790. (explain)

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

Pixel Rate

The GeForce GTX 1050 should be a lot (approximately 351%) more effective at FSAA than the Radeon HD 4790, and will be able to handle higher screen resolutions without slowing down too much. (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 (in units of MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
