GeForce 8300 GS (OEM) vs GeForce GTX 480

Intro

Compare those specifications to the GeForce GTX 480, which features GPU clock speed of 700 MHz, and 1536 MB of GDDR5 memory running at 924 MHz through a 384-bit bus. It also is comprised of 480 Stream Processors, 60 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 480		250 Watts
	Difference: 210 Watts (525%)

Memory Bandwidth

In theory, the GeForce GTX 480 should be much faster than the GeForce 8300 GS (OEM) in general. (explain)

GeForce GTX 480		177408 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 171008 (2672%)

Texel Rate

The GeForce GTX 480 will be a lot (more or less 2233%) more effective at AF than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 40200 (2233%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 480 is a better choice, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 32700 (3633%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
