GeForce GTS 450 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which features core clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 memory. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 5500 will be 297% quicker than the GeForce GTS 450 overall, because of its higher bandwidth. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GTS 450		57728 MB/sec
	Difference: 171648 (297%)

Texel Rate

The Radeon RX 5500 will be quite a bit (about 487%) more effective at AF than the GeForce GTS 450. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 121904 (487%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5500 is a better choice, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 40912 (327%)

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 largest amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at 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 graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
