Geforce GTX 670 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with GPU core 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 Raster Operation Units.

Radeon R5 M330		20600 Mtexels/sec
	Difference: 81880 (397%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 670 is superior to the Radeon R5 M330, 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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
