Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Geforce GTX 770		230 Watts
	Difference: 80 Watts (53%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 will be 2% quicker than the Geforce GTX 770 overall, due to its higher bandwidth. (explain)

Radeon RX 5500		229376 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 4992 (2%)

Texel Rate

The Radeon RX 5500 is just a bit (more or less 10%) faster with regards to anisotropic filtering than the Geforce GTX 770. (explain)

Radeon RX 5500		146960 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 13072 (10%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5500 is superior to the Geforce GTX 770, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 19968 (60%)

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 maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
