Radeon R9 380X vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which features a clock frequency of 2200 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 64-bit memory bus, and makes use of a 6 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon R9 380X		190 Watts
	Difference: 83 Watts (78%)

Memory Bandwidth

In theory, the Radeon R9 380X should be 24% faster than the Radeon RX 6500 XT in general, because of its higher bandwidth. (explain)

Radeon R9 380X		182400 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 34944 (24%)

Texel Rate

The Radeon RX 6500 XT should be a small bit (about 13%) faster with regards to texture filtering than the Radeon R9 380X. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R9 380X		124160 Mtexels/sec
	Difference: 16640 (13%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (about 127%) faster with regards to AA than the Radeon R9 380X, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R9 380X		31040 Mpixels/sec
	Difference: 39360 (127%)

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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
