GeForce GTX 460 1GB vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which has core speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 110 Watts (220%)

Memory Bandwidth

The GeForce GTX 460 1GB should theoretically be a little bit faster than the Radeon RX 550 in general. (explain)

GeForce GTX 460 1GB		115200 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 512 (0%)

Texel Rate

The GeForce GTX 460 1GB should be a bit (more or less 7%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 2600 (7%)

Pixel Rate

The GeForce GTX 460 1GB is much (approximately 23%) faster with regards to FSAA than the Radeon RX 550, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 4000 (23%)

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 across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 potential to reach the max fill rate.
