GeForce RTX 3080 vs Radeon HD 5550

Intro

Compare that to the Radeon HD 5550, which features a clock speed of 550 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 320(64x5) SPUs, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce RTX 3080 should be much faster than the Radeon HD 5550 overall. (explain)

GeForce RTX 3080		778547 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 765747 (5982%)

Texel Rate

The GeForce RTX 3080 should be much (more or less 4351%) more effective at texture filtering than the Radeon HD 5550. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 382880 (4351%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3080 is the winner, by a large margin. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 133840 (3042%)

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 max amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
