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

Intro

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

	Difference: 108800 (1700%)

Texel Rate

The GeForce GTX 460 1GB will be a lot (about 2000%) more effective 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is a better choice, 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
