GeForce GT 220 GDDR3 vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which comes with GPU clock speed of 725 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 220 GDDR3 will be 1% quicker than the Radeon R7 M265 overall, due to its higher data rate. (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 a lot (about 74%) faster with regards to texture 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

If using a high resolution is important to you, then the Radeon R7 M265 is a better choice, though not by far. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the 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 most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
