GeForce GTX 460 (OEM) vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which features GPU clock 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 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 will be 5% quicker than the GeForce GTX 460 (OEM) overall, because of its higher data rate. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 5888 (5%)

Texel Rate

The GeForce GTX 460 (OEM) is just a bit (about 3%) more effective at texture filtering than the Radeon RX 550. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 1200 (3%)

Pixel Rate

The GeForce GTX 460 (OEM) should be a little bit (more or less 18%) more effective at AA than the Radeon RX 550, and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 3200 (18%)

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 (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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.
