Radeon R9 270 vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 RAM works at a speed of 1500 MHz on this particular card. It features 2304 SPUs as well as 144 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 270		150 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT will be 92% quicker than the Radeon R9 270 overall, because of its greater bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon R9 270		179200 MB/sec
	Difference: 164864 (92%)

Texel Rate

The Radeon RX 5600 XT is much (more or less 175%) better at AF than the Radeon R9 270. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 126000 (175%)

Pixel Rate

The Radeon RX 5600 XT is quite a bit (about 206%) more effective at full screen anti-aliasing than the Radeon R9 270, and also able to handle higher resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 59200 (206%)

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 (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 in one second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
