GeForce 8300 GS (OEM) vs GeForce GTX 460 1GB

Intro

Compare that to the GeForce GTX 460 1GB, which has a core clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 120 Watts (300%)

Memory Bandwidth

In theory, the GeForce GTX 460 1GB is 1700% faster than the GeForce 8300 GS (OEM) overall, due to its greater data rate. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 108800 (1700%)

Texel Rate

The GeForce GTX 460 1GB should be quite a bit (about 2000%) better at texture filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 36000 (2000%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is the winner, and very much so. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 20700 (2300%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
