GeForce GT 340 vs GeForce GTX 295

Intro

Compare those specs to the GeForce GTX 295, which makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this specific model. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.

Texel Rate

The GeForce GTX 295 will be quite a bit (more or less 424%) more effective at texture filtering than the GeForce GT 340. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 74560 (424%)

Pixel Rate

The GeForce GTX 295 should be a lot (about 633%) more effective at FSAA than the GeForce GT 340, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 27856 (633%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
