GeForce 8300 GS (OEM) vs GeForce GTX 780 Ti

Intro

Compare all of that to the GeForce GTX 780 Ti, which has core clock speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 RAM. It features 2880 SPUs along with 240 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 210 Watts (525%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 780 Ti should in theory be quite a bit superior to the GeForce 8300 GS (OEM) in general. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 329600 (5150%)

Texel Rate

The GeForce GTX 780 Ti should be a lot (more or less 11567%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 208200 (11567%)

Pixel Rate

The GeForce GTX 780 Ti will be a lot (about 4567%) more effective at FSAA than the GeForce 8300 GS (OEM), and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 41100 (4567%)

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 MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure 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 video 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
