GeForce RTX 3080 vs Radeon HD 5770

Intro

Compare all of that to the Radeon HD 5770, which features a clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Radeon HD 5770		76800 MB/sec
	Difference: 701747 (914%)

Texel Rate

The GeForce RTX 3080 should be a lot (approximately 1052%) more effective at AF than the Radeon HD 5770. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 357680 (1052%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3080 is a better choice, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 124640 (916%)

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 megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 reach the max fill rate.
