GeForce GT 310 vs Radeon RX 550

Intro

Compare those specs to the Radeon RX 550, which has GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
Radeon RX 550		50 Watts
	Difference: 19 Watts (61%)

Memory Bandwidth

The Radeon RX 550 should in theory be much faster than the GeForce GT 310 in general. (explain)

Radeon RX 550		114688 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 98688 (617%)

Texel Rate

The Radeon RX 550 will be a lot (more or less 647%) better at AF than the GeForce GT 310. (explain)

Radeon RX 550		35200 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 30488 (647%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 550 is superior to the GeForce GT 310, and very much so. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 15244 (647%)

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 (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total 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 maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
