GeForce GTX 880M vs Radeon R5 M330

Intro

The GeForce GTX 880M uses a 28 nm design. nVidia has set the core speed at 954 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this model. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Compare all of that to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 memory runs at a frequency of 900 MHz on this model. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 880M, in theory, should perform much faster than the Radeon R5 M330 in general. (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%) better 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 880M is the winner, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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