GeForce GT 310 vs Radeon RX 550

Intro

The GeForce GT 310 features a GPU core clock speed of 589 MHz, and the 512 MB of DDR2 RAM runs at 1000 MHz through a 64-bit bus. It also features 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the Radeon RX 550, which uses a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM 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.

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

Texel Rate

The Radeon RX 550 should be quite a bit (more or less 647%) faster with regards to anisotropic filtering 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 high levels of AA is important to you, then the Radeon RX 550 is a better choice, by a large margin. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 fill 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 get to the max fill rate.
