GeForce GTX 295 vs GeForce GTX 465

Intro

Compare those specifications to the GeForce GTX 465, which comes with core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 memory. It features 352 SPUs as well as 44 TAUs and 32 Rasterization Operator Units.

GeForce GTX 465		102592 MB/sec
	Difference: 121184 (118%)

Texel Rate

The GeForce GTX 295 will be much (approximately 245%) better at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 65452 (245%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 295 is the winner, and very much so. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 12832 (66%)

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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
