GeForce 8300 GS (OEM) vs GeForce GT 340 1GB

Intro

Compare those specifications to the GeForce GT 340 1GB, which features core clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

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

Texel Rate

The GeForce GT 340 1GB will be quite a bit (more or less 878%) better at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 15800 (878%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 340 1GB is a better choice, and very much so. (explain)

GeForce GT 340 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, 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 number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
