GeForce GT 220 GDDR3 vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GT 220 GDDR3 should be a bit faster than the Radeon R7 M265 overall. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 384 (1%)

Texel Rate

The Radeon R7 M265 should be much (approximately 74%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 7400 (74%)

Pixel Rate

The Radeon R7 M265 should be a small bit (more or less 16%) faster with regards to FSAA than the GeForce GT 220 GDDR3, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 800 (16%)

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 megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
