GeForce GTX 460 1GB vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which features GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 512 SPUs, 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

In theory, the GeForce GTX 460 1GB will be 0% quicker than the Radeon RX 550 overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 460 1GB is just a bit (approximately 7%) more effective at AF 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 will be quite a bit (more or less 23%) better at anti-aliasing than the Radeon RX 550, and also will be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
