GeForce GT 450 (OEM) vs Radeon RX 5500

Intro

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

GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 is much (about 675%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 128000 (675%)

Pixel Rate

The Radeon RX 5500 should be quite a bit (approximately 182%) faster with regards to AA than the GeForce GT 450 (OEM), and should be able to handle higher resolutions better. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 34480 (182%)

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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
