GeForce GT 320 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core speed at 1030 MHz. The DDR3 RAM works at a frequency of 900 MHz on this specific model. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 320 should in theory be much superior to the Radeon R5 M330 overall. (explain)

GeForce GT 320		25280 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 10880 (76%)

Texel Rate

The Radeon R5 M330 should be much (about 59%) more effective at AF than the GeForce GT 320. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 7640 (59%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M330 is a better choice, and very much so. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 3920 (91%)

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 information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many 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.
