GeForce GTX 1050 vs Radeon HD 4790

Intro

The GeForce GTX 1050 features a GPU clock speed of 1354 MHz, and the 2048 MB of GDDR5 RAM runs at 1750 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon HD 4790, which comes with GPU clock speed of 600 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 256-bit bus. It also features 640(128x5) Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Radeon HD 4790 19200 Mtexels/sec
Difference: 34960 (182%)

Pixel Rate

The GeForce GTX 1050 should be a lot (about 351%) better at AA than the Radeon HD 4790, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, 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.
