Radeon HD 7750 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which features GPU clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 TAUs, and 32 ROPs.

As far as performance goes, the Radeon RX 5500 should in theory be quite a bit superior to the Radeon HD 7750 in general. (explain)

Radeon RX 5500		229376 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 will be a lot (more or less 474%) better at AF than the Radeon HD 7750. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 121360 (474%)

Pixel Rate

The Radeon RX 5500 should be quite a bit (approximately 318%) more effective at AA than the Radeon HD 7750, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 40640 (318%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 texture units by the core clock speed of the chip. The better this number, 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 maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
