Geforce GTX 780 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which has core clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 memory. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Geforce GTX 780		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 should be 26% quicker than the Radeon RX 5500 in general, due to its greater bandwidth. (explain)

Geforce GTX 780		288384 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 59008 (26%)

Texel Rate

The Geforce GTX 780 is a little bit (more or less 13%) better at anisotropic filtering than the Radeon RX 5500. (explain)

Geforce GTX 780		165696 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 18736 (13%)

Pixel Rate

The Radeon RX 5500 will be quite a bit (about 29%) faster with regards to full screen anti-aliasing than the Geforce GTX 780, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5500		53440 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 12016 (29%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
