GeForce GTX 1050 vs Radeon HD 4790

Intro

Compare all of that to the Radeon HD 4790, which features a clock speed of 600 MHz and a GDDR5 memory speed of 800 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce GTX 1050 is much (about 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 is much (approximately 351%) better at full screen anti-aliasing than the Radeon HD 4790, and also should be able to handle higher screen resolutions while still performing well. (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 (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core 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 is also dependant on quite a few 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.
