GeForce 9800 GX2 vs GeForce GT 340

Intro

The GeForce 9800 GX2 comes with a core clock frequency of 600 MHz and a GDDR3 memory speed of 1000 MHz. It also features a 256-bit bus, and makes use of a 65 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the GeForce GT 340, which features core clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 69 Watts
GeForce 9800 GX2 197 Watts
Difference: 128 Watts (186%)

Memory Bandwidth

As far as performance goes, the GeForce 9800 GX2 should in theory be a lot superior to the GeForce GT 340 in general. (explain)

GeForce 9800 GX2 128000 MB/sec
GeForce GT 340 54400 MB/sec
Difference: 73600 (135%)

Texel Rate

The GeForce 9800 GX2 should be quite a bit (approximately 336%) better at texture filtering than the GeForce GT 340. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce GT 340 17600 Mtexels/sec
Difference: 59200 (336%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is a better choice, by a large margin. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce GT 340 4400 Mpixels/sec
Difference: 14800 (336%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. Pixel rate is calculated by multiplying the amount of Render Output Units 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
