GeForce 8300 GS (OEM) vs GeForce GTX 470

Intro

Compare that to the GeForce GTX 470, which features GPU core speed of 607 MHz, and 1280 MB of GDDR5 RAM set to run at 837 MHz through a 320-bit bus. It also is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

The GeForce GTX 470 will be a lot (more or less 1788%) faster with regards to anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 32192 (1788%)

Pixel Rate

The GeForce GTX 470 is much (approximately 2598%) better at FSAA than the GeForce 8300 GS (OEM), and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 23380 (2598%)

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 moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
