GeForce GTX 850M vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which makes use of a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 memory works at a frequency of 900 MHz on this model. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 850M should perform a lot faster than the Radeon R5 M330 overall. (explain)

GeForce GTX 850M		32000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The GeForce GTX 850M should be much (approximately 70%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 850M		35040 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 14440 (70%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 850M is superior to the Radeon R5 M330, by far. (explain)

GeForce GTX 850M		14016 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 5776 (70%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
