GeForce 940M vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which uses a 28 nm design. AMD has set the core speed at 1030 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this model. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 940M should be a bit faster than the Radeon R5 M330 in general. (explain)

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

Texel Rate

The GeForce 940M should be quite a bit (more or less 25%) faster with regards to AF than the Radeon R5 M330. (explain)

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

Pixel Rate

The GeForce 940M should be a little bit (about 4%) better at full screen anti-aliasing than the Radeon R5 M330, and also should be capable of handling higher resolutions more effectively. (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 largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
