GeForce 940M vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which has GPU clock speed of 780 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce 940M should be much (approximately 65%) better at texture filtering than the Radeon R5 M230. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 10128 (65%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 940M is a better choice, by far. (explain)

GeForce 940M		8576 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 5456 (175%)

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 max amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
