Geforce GTX 770 vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which comes with GPU clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 1408 Stream Processors, 88 TAUs, and 32 Raster Operation Units.

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

In theory, the Radeon RX 5500 will be 2% quicker than the Geforce GTX 770 overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 5500 is a little bit (about 10%) more effective at texture 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 lots of anti-aliasing is important to you, then the Radeon RX 5500 is a better choice, 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 max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
