GeForce GTX 285 1GB vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this model. 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 285 1GB		204 Watts
	Difference: 154 Watts (308%)

Memory Bandwidth

In theory, the GeForce GTX 285 1GB should be 39% quicker than the Radeon RX 550 in general, because of its higher data rate. (explain)

GeForce GTX 285 1GB		158976 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 44288 (39%)

Texel Rate

The GeForce GTX 285 1GB will be quite a bit (approximately 47%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 16640 (47%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 285 1GB is superior to the Radeon RX 550, but it probably won't make a huge difference. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 3136 (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 max amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
