GeForce RTX 3070 Ti vs Radeon R7 250X 2GB

Intro

Compare those specifications to the Radeon R7 250X 2GB, which comes with core clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Radeon R7 250X 2GB		95 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 195 Watts (205%)

Memory Bandwidth

Theoretically, the GeForce RTX 3070 Ti should perform quite a bit faster than the Radeon R7 250X 2GB overall. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 550899 (765%)

Texel Rate

The GeForce RTX 3070 Ti should be a lot (more or less 656%) more effective at AF than the Radeon R7 250X 2GB. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 262400 (656%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3070 Ti is a better choice, by far. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 135200 (845%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
