GeForce GTX 880M vs Radeon R5 M330

Intro

The GeForce GTX 880M comes with a core clock speed of 954 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It features 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare all that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has set the core frequency at 1030 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular model. 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 will be 789% faster than the Radeon R5 M330 in general, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 880M will be quite a bit (about 493%) better at texture 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 anti-aliasing than the Radeon R5 M330, and capable of handling higher resolutions better. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one 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 higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record 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 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
