Geforce GTX 770 vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which uses a 7 nm design. AMD has set the core speed at 1670 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this specific card. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

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% faster than the Geforce GTX 770 in general, due to its greater data rate. (explain)

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

Texel Rate

The Radeon RX 5500 will be a little bit (about 10%) more effective at 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

The Radeon RX 5500 is quite a bit (approximately 60%) faster with regards to anti-aliasing than the Geforce GTX 770, and capable of handling higher screen resolutions without losing too much performance. (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 largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
