GeForce GTX 1050 3GB vs Radeon HD 5770

Intro

Compare that to the Radeon HD 5770, which comes with clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Radeon HD 5770		76800 MB/sec
	Difference: 9216 (12%)

Texel Rate

The GeForce GTX 1050 3GB should be quite a bit (approximately 97%) faster with regards to anisotropic filtering than the Radeon HD 5770. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 32816 (97%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1050 3GB is a better choice, and very much so. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 19808 (146%)

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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock 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 output 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.
