GeForce 9800 GTX+ vs GeForce GT 340

Intro

Compare those specifications to the GeForce GT 340, which uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this specific model. It features 96 SPUs along with 32 TAUs and 8 ROPs.

GeForce GT 340		54400 MB/sec
	Difference: 16000 (29%)

Texel Rate

The GeForce 9800 GTX+ is a lot (approximately 168%) better at anisotropic filtering than the GeForce GT 340. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 29632 (168%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9800 GTX+ is a better choice, by a large margin. (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
