GeForce GT 220 GDDR3 vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which has clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380, in theory, should be a lot faster than the GeForce GT 220 GDDR3 overall. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 63616 (196%)

Texel Rate

The Radeon R9 M380 will be quite a bit (more or less 300%) better at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 30000 (300%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M380 is a better choice, by far. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 11000 (220%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
