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

Intro

Compare those specs to the GeForce GT 340 1GB, which makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this specific model. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Texel Rate

The GeForce GT 340 1GB is much (more or less 878%) more effective at AF 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 using high levels of AA is important to you, then the GeForce GT 340 1GB is the winner, by far. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 graphics 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 video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. 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.
