Radeon R9 M380 vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which features a GPU core clock speed of 1925 MHz, and 16384 MB of GDDR6 RAM set to run at 2250 MHz through a 256-bit bus. It also features 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 6950 XT should theoretically be a lot better than the Radeon R9 M380 overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 493824 (514%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (more or less 1440%) faster with regards to AF than the Radeon R9 M380. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 576000 (1440%)

Pixel Rate

The Radeon RX 6950 XT should be quite a bit (about 1440%) faster with regards to full screen anti-aliasing than the Radeon R9 M380, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 230400 (1440%)

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 information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
