GeForce GTX 275 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 275 should be 11% faster than the Radeon RX 550 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 275 is quite a bit (more or less 44%) more effective at texture 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 running with 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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number 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 applied in a 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 figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
