Radeon R7 250X 2GB vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which has GPU core speed of 2200 MHz, and 4096 MB of GDDR6 RAM running at 2250 MHz through a 64-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X 2GB		95 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 12 Watts (13%)

Memory Bandwidth

The Radeon RX 6500 XT, in theory, should be much faster than the Radeon R7 250X 2GB in general. (explain)

Radeon RX 6500 XT		147456 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 75456 (105%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (approximately 252%) better at AF than the Radeon R7 250X 2GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 100800 (252%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 340%) more effective at anti-aliasing than the Radeon R7 250X 2GB, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 54400 (340%)

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 max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
