GeForce GT 340 vs GeForce GTX 460 (OEM)

Intro

Compare all that to the GeForce GTX 460 (OEM), which comes with core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 340		54400 MB/sec
	Difference: 54400 (100%)

Texel Rate

The GeForce GTX 460 (OEM) should be quite a bit (more or less 107%) better at AF than the GeForce GT 340. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 18800 (107%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is a better choice, by far. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 16400 (373%)

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 (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
