GeForce GT 220 GDDR3 vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X should perform a lot faster than the GeForce GT 220 GDDR3 in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 63616 (196%)

Texel Rate

The Radeon R9 M385X is much (about 516%) better at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 51600 (516%)

Pixel Rate

The Radeon R9 M385X is quite a bit (approximately 252%) more effective at anti-aliasing than the GeForce GT 220 GDDR3, and able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 12600 (252%)

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 (measured in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 potential to get to the maximum fill rate.
