GeForce GT 220 GDDR3 vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which has GPU clock speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375 should in theory perform just a bit faster than the GeForce GT 220 GDDR3 in general. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 2816 (9%)

Texel Rate

The Radeon R9 M375 should be a lot (more or less 306%) more effective at AF than the GeForce GT 220 GDDR3. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 30600 (306%)

Pixel Rate

The Radeon R9 M375 should be quite a bit (about 225%) better at AA than the GeForce GT 220 GDDR3, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 11240 (225%)

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 max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
