GeForce GTX 275 vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Radeon RX 550		50 Watts
GeForce GTX 275		219 Watts
	Difference: 169 Watts (338%)

Memory Bandwidth

The GeForce GTX 275 should theoretically be a little bit faster than the Radeon RX 550 in general. (explain)

GeForce GTX 275		127008 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 12320 (11%)

Texel Rate

The GeForce GTX 275 is much (approximately 44%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 275		50640 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 15440 (44%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 275 is superior to the Radeon RX 550, though not by far. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 124 (1%)

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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated 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 most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
