GeForce GTX 1630 vs Radeon RX 550

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
GeForce GTX 1630		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

Performance-wise, the Radeon RX 550 should in theory be a small bit superior to the GeForce GTX 1630 overall. (explain)

Radeon RX 550		114688 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 16384 (17%)

Texel Rate

The GeForce GTX 1630 should be a lot (more or less 58%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 20480 (58%)

Pixel Rate

The GeForce GTX 1630 will be much (approximately 58%) faster with regards to AA than the Radeon RX 550, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 10240 (58%)

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 (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
