Radeon R9 M385X vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1925 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this card. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 6950 XT should perform much faster than the Radeon R9 M385X overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 493824 (514%)

Texel Rate

The Radeon RX 6950 XT should be a lot (more or less 900%) better at anisotropic filtering than the Radeon R9 M385X. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 554400 (900%)

Pixel Rate

The Radeon RX 6950 XT will be a lot (about 1300%) more effective at AA than the Radeon R9 M385X, and will be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 228800 (1300%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum 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 the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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