GeForce GTX 960M vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features a clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960M will be 344% quicker than the Radeon R5 M330 overall, because of its higher bandwidth. (explain)

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

Texel Rate

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

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

Pixel Rate

The GeForce GTX 960M is a lot (more or less 113%) better at AA than the Radeon R5 M330, and also will be capable of handling higher resolutions without losing too much performance. (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 largest amount of data (measured in megabytes per second) that can be transported across 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 should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
