GeForce 8300 GS (OEM) vs GeForce GTX 980

Intro

Compare all of that to the GeForce GTX 980, which has a core clock frequency of 1126 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 142328 (7907%)

Pixel Rate

The GeForce GTX 980 should be much (approximately 7907%) better at AA than the GeForce 8300 GS (OEM), and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 71164 (7907%)

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 max amount of data (measured in megabytes 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. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 per second. This figure is worked out by multiplying the total number of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
