Radeon R9 270 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core frequency at 1717 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this particular card. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon R9 270		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT will be 28% faster than the Radeon R9 270 in general, due to its greater bandwidth. (explain)

Radeon RX 5500 XT		229376 MB/sec
Radeon R9 270		179200 MB/sec
	Difference: 50176 (28%)

Texel Rate

The Radeon RX 5500 XT is a lot (more or less 110%) faster with regards to AF than the Radeon R9 270. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 79096 (110%)

Pixel Rate

The Radeon RX 5500 XT should be much (about 91%) more effective at anti-aliasing than the Radeon R9 270, and should be capable of handling higher screen resolutions better. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 26144 (91%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
