GeForce GTX 1050 3GB vs Radeon HD 4790

Intro

Compare those specs to the Radeon HD 4790, which has GPU core speed of 600 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 256-bit bus. It also is made up of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 16384 (19%)

Texel Rate

The GeForce GTX 1050 3GB should be a lot (approximately 248%) better at anisotropic filtering than the Radeon HD 4790. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 47616 (248%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 3GB is superior to the Radeon HD 4790, by far. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 23808 (248%)

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: Bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
