Radeon R9 M380 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has set the core speed at 1968 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 6600 XT should in theory be a lot better than the Radeon R9 M380 overall. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 166144 (173%)

Texel Rate

The Radeon RX 6600 XT will be much (approximately 530%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 211904 (530%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 XT is the winner, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 109952 (687%)

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 transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
