GeForce GTX 1050 vs Radeon HD 4790

Intro

Compare those specifications to the Radeon HD 4790, which uses a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR5 memory is set to run at a speed of 800 MHz on this specific model. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Radeon HD 4790		102400 MB/sec
	Difference: 12288 (12%)

Texel Rate

The GeForce GTX 1050 is quite a bit (more or less 182%) faster with regards to 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 is quite a bit (more or less 351%) faster with regards to FSAA than the Radeon HD 4790, and will be capable of handling higher resolutions more effectively. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
