GeForce GTX 1050 vs Radeon HD 4790

Intro

The GeForce GTX 1050 makes use of a 14 nm design. nVidia has clocked the core speed at 1354 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4790, which makes use of 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 specific model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 1050 should in theory perform a little bit faster than the Radeon HD 4790 overall. (explain)

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

Texel Rate

The GeForce GTX 1050 will be a lot (approximately 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 superior to the Radeon HD 4790, 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 clock speed of the chip. The higher this number, the better the 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 that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
