GeForce GT 130 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M330 will be 20% quicker than the GeForce GT 130 overall, because of its higher data rate. (explain)

Radeon R5 M330		14400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 2400 (20%)

Texel Rate

The Radeon R5 M330 should be quite a bit (more or less 72%) more effective at texture filtering than the GeForce GT 130. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 8600 (72%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R5 M330 is the winner, but only just. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 240 (3%)

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 (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
