GeForce 8300 GS (OEM) vs GeForce GTX Titan

Intro

Compare those specifications to the GeForce GTX Titan, which comes with clock speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 memory. It features 2688 SPUs along with 224 Texture Address Units and 48 Rasterization Operator Units.

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX Titan		250 Watts
	Difference: 210 Watts (525%)

Memory Bandwidth

In theory, the GeForce GTX Titan will be 4406% faster than the GeForce 8300 GS (OEM) overall, because of its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 281984 (4406%)

Texel Rate

The GeForce GTX Titan should be a lot (about 10316%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 185688 (10316%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 39276 (4364%)

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 (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
