GeForce RTX 3080 Ti vs Radeon R7 250X

Intro

Compare those specifications to the Radeon R7 250X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 255 Watts (268%)

Memory Bandwidth

The GeForce RTX 3080 Ti, in theory, should be quite a bit faster than the Radeon R7 250X in general. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 862297 (1198%)

Texel Rate

The GeForce RTX 3080 Ti should be a lot (about 992%) more effective at anisotropic filtering than the Radeon R7 250X. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 396800 (992%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is a better choice, and very much so. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 136880 (856%)

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 (measured in megabytes 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 the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, 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 most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
