GeForce 830M vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory works at a speed of 1150 MHz on this particular card. It features 720(144x5) SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
Radeon HD 5750 1GB		86 Watts
	Difference: 61 Watts (244%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB is 411% faster than the GeForce 830M overall, because of its higher bandwidth. (explain)

Radeon HD 5750 1GB		73600 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The Radeon HD 5750 1GB is quite a bit (about 53%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 8736 (53%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is a better choice, and very much so. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 2968 (36%)

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 information (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
