GeForce 8300 GS (OEM) vs GeForce GT 240 GDDR5 1GB

Intro

Compare that to the GeForce GT 240 GDDR5 1GB, which makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM works at a speed of 850 MHz on this particular model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 15800 (878%)

Pixel Rate

The GeForce GT 240 GDDR5 1GB should be quite a bit (about 389%) more effective at FSAA than the GeForce 8300 GS (OEM), and should be capable of handling higher resolutions while still performing well. (explain)

GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 3500 (389%)

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 transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better 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 most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
