In theory, the GeForce GTX 970M will be 1400% faster than the GeForce 8300 GS (OEM) overall, because of its greater bandwidth. (explain)

GeForce GTX 970M		96000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 89600 (1400%)

Texel Rate

The GeForce GTX 970M is quite a bit (about 4007%) faster with regards to texture filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 72120 (4007%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 970M is superior to the GeForce 8300 GS (OEM), by far. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 43452 (4828%)

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 information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
