GeForce GTX 950M vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with GPU core speed of 1030 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 950M should theoretically be a lot superior to the Radeon R5 M330 in general. (explain)

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

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 77%) faster with regards to AF 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 superior to the Radeon R5 M330, by far. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
