Radeon HD 6770 vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which has core clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Radeon HD 6770		108 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 52 Watts (48%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT will be 412% quicker than the Radeon HD 6770 in general, due to its higher data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon HD 6770		67200 MB/sec
	Difference: 276864 (412%)

Texel Rate

The Radeon RX 5600 XT will be quite a bit (more or less 450%) better at anisotropic filtering than the Radeon HD 6770. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon HD 6770		36000 Mtexels/sec
	Difference: 162000 (450%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5600 XT is the winner, by far. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon HD 6770		14400 Mpixels/sec
	Difference: 73600 (511%)

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 largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
