GeForce GTX 950M vs Radeon R5 M330

Intro

The GeForce GTX 950M features a clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare those specs to the Radeon R5 M330, which comes with a clock speed of 1030 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 950M should in theory be a lot better than the Radeon R5 M330 overall. (explain)

GeForce GTX 950M 32000 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 17600 (122%)

Texel Rate

The GeForce GTX 950M should be a lot (about 77%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 950M 36560 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 15960 (77%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, and very much so. (explain)

GeForce GTX 950M 14624 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 6384 (77%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
