Geforce GTX 670 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which has core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Geforce GTX 670 should be a lot faster than the Radeon R5 M330 overall. (explain)

Geforce GTX 670		192000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 177600 (1233%)

Texel Rate

The Geforce GTX 670 will be much (more or less 397%) better at texture filtering than the Radeon R5 M330. (explain)

Geforce GTX 670		102480 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 81880 (397%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 670 is a better choice, by far. (explain)

Geforce GTX 670		29280 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 21040 (255%)

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 (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
