GeForce 8300 GS (OEM) vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which has a clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 560		150 Watts
	Difference: 110 Watts (275%)

Memory Bandwidth

In theory, the GeForce GTX 560 should be 1902% quicker than the GeForce 8300 GS (OEM) in general, because of its higher data rate. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 121728 (1902%)

Texel Rate

The GeForce GTX 560 is quite a bit (approximately 2420%) faster with regards to texture filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 43560 (2420%)

Pixel Rate

The GeForce GTX 560 should be much (about 2780%) more effective at anti-aliasing than the GeForce 8300 GS (OEM), and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 25020 (2780%)

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out 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 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 maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
