GeForce GT 210 vs Radeon R5 M255

Intro

Compare all that to the Radeon R5 M255, which comes with a core clock speed of 940 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

GeForce GT 210		4712 Mtexels/sec
	Difference: 14088 (299%)

Pixel Rate

The Radeon R5 M255 should be a lot (approximately 219%) better at anti-aliasing than the GeForce GT 210, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon R5 M255		7520 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5164 (219%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, 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 maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's 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 also depends on quite a few 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.
