GeForce 9800 GTX+ vs GeForce GT 340 1GB

Intro

Compare that to the GeForce GT 340 1GB, which has a GPU core clock speed of 550 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Texel Rate

The GeForce 9800 GTX+ will be quite a bit (approximately 168%) faster with regards to texture filtering than the GeForce GT 340 1GB. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 29632 (168%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 9800 GTX+ is superior to the GeForce GT 340 1GB, and very much so. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 340 1GB		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 maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
