GeForce GTX 880M vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core frequency at 1030 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this specific card. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 880M is 789% quicker than the Radeon R5 M330 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 880M is quite a bit (about 493%) more effective at anisotropic filtering 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 is quite a bit (about 270%) more effective at AA than the Radeon R5 M330, and able to handle higher screen resolutions while still performing well. (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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can 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 Render Output Units 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
