GeForce GT 220 GDDR3 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which uses a 28 nm design. AMD has clocked the core frequency at 780 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this card. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GT 220 GDDR3 should in theory be a lot better than the Radeon R5 M230 overall. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 16384 (102%)

Texel Rate

The Radeon R5 M230 is quite a bit (more or less 56%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 5600 (56%)

Pixel Rate

The GeForce GT 220 GDDR3 is much (about 60%) more effective at full screen anti-aliasing than the Radeon R5 M230, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1880 (60%)

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 data (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 get to the max fill rate.
