GeForce 8300 GS (OEM) vs GeForce 830M

Intro

Compare all of that to the GeForce 830M, which uses a 28 nm design. nVidia has clocked the core speed at 1029 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular model. It features 256 SPUs along with 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
GeForce 8300 GS (OEM)		40 Watts
	Difference: 15 Watts (60%)

Memory Bandwidth

In theory, the GeForce 830M is 125% quicker than the GeForce 8300 GS (OEM) overall, due to its greater bandwidth. (explain)

GeForce 830M		14400 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 8000 (125%)

Texel Rate

The GeForce 830M is quite a bit (about 815%) better at texture filtering than the GeForce 8300 GS (OEM). (explain)

GeForce 830M		16464 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 14664 (815%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 830M is the winner, and very much so. (explain)

GeForce 830M		8232 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 7332 (815%)

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 largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
