GeForce GT 450 (OEM) vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which has a core clock speed of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
Radeon RX 5500		150 Watts
	Difference: 44 Watts (42%)

Memory Bandwidth

The Radeon RX 5500, in theory, should perform a lot faster than the GeForce GT 450 (OEM) in general. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 will be much (more or less 675%) more effective at AF 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 (about 182%) more effective at full screen anti-aliasing than the GeForce GT 450 (OEM), and will be capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 the video card can possibly write to its local memory in a 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
