GeForce 8300 GS (OEM) vs GeForce GT 340

Intro

Compare those specifications to the GeForce GT 340, which has core speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
GeForce GT 340		69 Watts
	Difference: 29 Watts (73%)

Memory Bandwidth

The GeForce GT 340, in theory, should perform quite a bit faster than the GeForce 8300 GS (OEM) overall. (explain)

GeForce GT 340		54400 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 48000 (750%)

Texel Rate

The GeForce GT 340 should be much (more or less 878%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GT 340		17600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 15800 (878%)

Pixel Rate

The GeForce GT 340 will be quite a bit (more or less 389%) faster with regards to AA than the GeForce 8300 GS (OEM), and should be able to handle higher resolutions better. (explain)

GeForce GT 340		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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
