GeForce 940M vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which has GPU core speed of 575 MHz, and 512 MB of DDR2 RAM running at 500 MHz through a 64-bit bus. It also features 80(16x5) Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 940M should in theory be a lot superior to 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 will be quite a bit (approximately 459%) better at anisotropic filtering than the Radeon HD 4350. (explain)

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

Pixel Rate

The GeForce 940M is much (about 273%) more effective at FSAA than the Radeon HD 4350, and should be able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
