GeForce GTX 970 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 memory running at 900 MHz through a 64-bit bus. It also features 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 970, in theory, should perform a lot faster than the Radeon R5 M330 overall. (explain)

GeForce GTX 970		224000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 209600 (1456%)

Texel Rate

The GeForce GTX 970 will be quite a bit (about 430%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 970		109200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 88600 (430%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 970 is the winner, and very much so. (explain)

GeForce GTX 970		67200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 58960 (716%)

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 megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
