GeForce GT 320 vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core speed at 1030 MHz. The DDR3 RAM is set to run at a speed 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

Theoretically speaking, the GeForce GT 320 is 76% faster than the Radeon R5 M330 in general, because of its higher data rate. (explain)

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

Texel Rate

The Radeon R5 M330 is much (more or less 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 the winner, 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: Bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 applied in one second. This is worked out by multiplying the total number of texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
