GeForce GTX 980 Ti vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which has a clock frequency of 1670 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980 Ti will be 46% quicker than the Radeon RX 5500 in general, because of its higher bandwidth. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The GeForce GTX 980 Ti will be a little bit (approximately 20%) better at AF than the Radeon RX 5500. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 29040 (20%)

Pixel Rate

The GeForce GTX 980 Ti is much (approximately 80%) faster with regards to anti-aliasing than the Radeon RX 5500, and should be able to handle higher screen resolutions better. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 42560 (80%)

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 data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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.
