GeForce 940M vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 RAM works at a speed of 1000 MHz on this specific model. It features 320 SPUs along with 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The GeForce 940M is a lot (more or less 65%) more effective 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 using 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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, 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 most pixels the video card could 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 Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
