GeForce 940M vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 940M should perform a little bit faster than the Radeon R5 M330 overall. (explain)

GeForce 940M		16000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 940M will be quite a bit (approximately 25%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 5128 (25%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 940M is superior to the Radeon R5 M330, but not by far. (explain)

GeForce 940M		8576 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 336 (4%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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.
