GeForce RTX 2080 SUPER vs Radeon R7 250X

Intro

Compare those specifications to the Radeon R7 250X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 155 Watts (163%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should be 605% faster than the Radeon R7 250X overall, because of its higher data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 435904 (605%)

Texel Rate

The GeForce RTX 2080 SUPER will be a lot (about 692%) better at texture filtering than the Radeon R7 250X. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 276800 (692%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is a better choice, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 89600 (560%)

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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
