GeForce GT 220 GDDR3 vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which comes with core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375, in theory, should perform a little 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 will be a lot (more or less 306%) faster with regards to texture filtering 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

If running with a high resolution is important to you, then the Radeon R9 M375 is a better choice, and very much so. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of 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 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 graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
