GeForce RTX 3080 Ti vs Radeon R7 250

Intro

Compare those specs to the Radeon R7 250, which comes with GPU core speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250		65 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 285 Watts (438%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti is 1169% quicker than the Radeon R7 250 overall, because of its higher data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 860697 (1169%)

Texel Rate

The GeForce RTX 3080 Ti should be a lot (approximately 1720%) more effective at texture filtering than the Radeon R7 250. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 412800 (1720%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is the winner, and very much so. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 144880 (1811%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
