Geforce GTX 680 vs Radeon RX 5500

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Geforce GTX 680		195 Watts
	Difference: 45 Watts (30%)

Memory Bandwidth

In theory, the Radeon RX 5500 should be 19% quicker than the Geforce GTX 680 overall, because of its greater bandwidth. (explain)

Radeon RX 5500		229376 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 37120 (19%)

Texel Rate

The Radeon RX 5500 will be a little bit (more or less 14%) better at texture filtering than the Geforce GTX 680. (explain)

Radeon RX 5500		146960 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 18192 (14%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5500 is a better choice, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 21248 (66%)

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 moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 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. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.
