GeForce 9800 GTX+ vs GeForce GT 340

Intro

Compare those specifications to the GeForce GT 340, which features a GPU core clock speed of 550 MHz, and 512 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 TAUs, and 8 ROPs.

GeForce GT 340		17600 Mtexels/sec
	Difference: 29632 (168%)

Pixel Rate

The GeForce 9800 GTX+ should be much (about 168%) more effective at AA than the GeForce GT 340, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 7408 (168%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are applied per second. This number is calculated by multiplying the total texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
