Radeon RX 5500 vs Radeon RX 5700

Intro

Compare all that to the Radeon RX 5700, which has GPU core speed of 1465 MHz, and 8096 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Radeon RX 5500		150 Watts
Radeon RX 5700		180 Watts
	Difference: 30 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 is 100% quicker than the Radeon RX 5500 in general, because of its greater data rate. (explain)

Radeon RX 5700		458752 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The Radeon RX 5700 should be a lot (about 44%) more effective at anisotropic filtering than the Radeon RX 5500. (explain)

Radeon RX 5700		210960 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 64000 (44%)

Pixel Rate

The Radeon RX 5700 will be a lot (about 75%) better at FSAA than the Radeon RX 5500, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 40320 (75%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core 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 maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
