GeForce GTX 970 vs Radeon RX 5500

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970		145 Watts
Radeon RX 5500		150 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

The Radeon RX 5500 should theoretically be just a bit faster than the GeForce GTX 970 in general. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GTX 970		224000 MB/sec
	Difference: 5376 (2%)

Texel Rate

The Radeon RX 5500 is quite a bit (more or less 35%) faster with regards to anisotropic filtering than the GeForce GTX 970. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 37760 (35%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 970 is the winner, by far. (explain)

GeForce GTX 970		67200 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 13760 (26%)

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 MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
