Radeon R7 250X vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which has GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 memory set to run at 2250 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 TAUs, and 128 ROPs.

Radeon R7 250X		72000 MB/sec
	Difference: 517824 (719%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (more or less 1440%) more effective at AF than the Radeon R7 250X. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 576000 (1440%)

Pixel Rate

The Radeon RX 6950 XT should be quite a bit (more or less 1440%) better at FSAA than the Radeon R7 250X, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R7 250X		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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
