GeForce GTX 960M vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which comes with clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 960M, in theory, should be a lot faster than the Radeon R5 M330 in general. (explain)

GeForce GTX 960M		64000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce GTX 960M should be quite a bit (about 113%) more effective at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 23240 (113%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960M is a better choice, by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 9296 (113%)

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 MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
