GeForce 8300 GS (OEM) vs GeForce GTX 460 2GB

Intro

Compare all that to the GeForce GTX 460 2GB, which makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory works at a speed of 900 MHz on this particular model. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

GeForce GTX 460 2GB		37800 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 36000 (2000%)

Pixel Rate

The GeForce GTX 460 2GB should be a lot (about 2300%) faster with regards to FSAA than the GeForce 8300 GS (OEM), and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 2GB		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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface 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 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
