Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 should be 99% faster than the GeForce GTX 460 2GB in general, due to its higher data rate. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GTX 460 2GB		115200 MB/sec
	Difference: 114176 (99%)

Texel Rate

The Radeon RX 5500 should be quite a bit (approximately 289%) faster with regards to anisotropic filtering than the GeForce GTX 460 2GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 109160 (289%)

Pixel Rate

The Radeon RX 5500 should be quite a bit (more or less 147%) better at FSAA than the GeForce GTX 460 2GB, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 31840 (147%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
