GeForce 8800 GT 1GB vs GeForce GTX 980M

Intro

Compare all of that to the GeForce GTX 980M, which comes with core speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1536 SPUs along with 96 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M		100 Watts
GeForce 8800 GT 1GB		105 Watts
	Difference: 5 Watts (5%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980M should be 122% quicker than the GeForce 8800 GT 1GB overall, due to its greater data rate. (explain)

GeForce GTX 980M		128000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 70400 (122%)

Texel Rate

The GeForce GTX 980M should be a lot (approximately 197%) more effective at texture filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 980M		99648 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 66048 (197%)

Pixel Rate

The GeForce GTX 980M will be quite a bit (more or less 592%) faster with regards to FSAA than the GeForce 8800 GT 1GB, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 980M		66432 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 56832 (592%)

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. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
