GeForce 940M vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which has a GPU core clock speed of 575 MHz, and 512 MB of DDR2 RAM set to run at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 940M should be quite a bit faster than the Radeon HD 4350 in general. (explain)

GeForce 940M		16000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 8000 (100%)

Texel Rate

The GeForce 940M should be quite a bit (more or less 459%) more effective at texture filtering than the Radeon HD 4350. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 21128 (459%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 940M is the winner, by a large margin. (explain)

GeForce 940M		8576 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 6276 (273%)

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 data (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
