Radeon HD 6770 vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 memory is set to run at a frequency of 2250 MHz on this model. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 6500 XT		107 Watts
Radeon HD 6770		108 Watts
	Difference: 1 Watts (1%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT will be 119% faster than the Radeon HD 6770 overall, due to its greater data rate. (explain)

Radeon RX 6500 XT		147456 MB/sec
Radeon HD 6770		67200 MB/sec
	Difference: 80256 (119%)

Texel Rate

The Radeon RX 6500 XT should be a lot (approximately 291%) more effective at AF than the Radeon HD 6770. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 6770		36000 Mtexels/sec
	Difference: 104800 (291%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (approximately 389%) faster with regards to AA than the Radeon HD 6770, and should be able to handle higher resolutions better. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 6770		14400 Mpixels/sec
	Difference: 56000 (389%)

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 (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
