GeForce GT 315 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which comes with a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GT 315 should theoretically be much better than the Radeon R5 M330 overall. (explain)

GeForce GT 315		25280 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 10880 (76%)

Texel Rate

The Radeon R5 M330 should be a lot (more or less 106%) faster with regards to texture filtering than the GeForce GT 315. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 10600 (106%)

Pixel Rate

If running with a high 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 315		5000 Mpixels/sec
	Difference: 3240 (65%)

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 information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 maximum amount of pixels the video card 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
