GeForce GTX 1070 Ti vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which comes with GPU clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
GeForce GTX 1070 Ti		180 Watts
	Difference: 30 Watts (20%)

Memory Bandwidth

In theory, the GeForce GTX 1070 Ti should be 14% quicker than the Radeon RX 5500 in general, due to its greater data rate. (explain)

GeForce GTX 1070 Ti		262144 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The GeForce GTX 1070 Ti should be much (more or less 66%) faster with regards to anisotropic filtering than the Radeon RX 5500. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 97304 (66%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1070 Ti is superior to the Radeon RX 5500, by a large margin. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 49408 (92%)

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 (in units of MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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