GeForce GTX 880M vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this card. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 880M should be much faster than the Radeon R5 M330 overall. (explain)

GeForce GTX 880M		128000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The GeForce GTX 880M is a lot (more or less 493%) more effective at AF than the Radeon R5 M330. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 101512 (493%)

Pixel Rate

The GeForce GTX 880M should be much (about 270%) better at AA than the Radeon R5 M330, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 880M		30528 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 22288 (270%)

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 (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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.
