Geforce GTX 780 vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which comes with a GPU core 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 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

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

Memory Bandwidth

As far as performance goes, the Geforce GTX 780 should in theory be quite a bit better than the Radeon RX 5500 in general. (explain)

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

Texel Rate

The Geforce GTX 780 is just a bit (approximately 13%) better at AF 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 should be a lot (approximately 29%) better at AA than the Geforce GTX 780, and should be able to handle higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
