GeForce GTX 295 vs GeForce GTX 465

Intro

Compare all of that to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM is set to run at a speed of 802 MHz on this specific model. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.

GeForce GTX 465		200 Watts
GeForce GTX 295		289 Watts
	Difference: 89 Watts (45%)

Memory Bandwidth

In theory, the GeForce GTX 295 should perform a lot faster than the GeForce GTX 465 overall. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 121184 (118%)

Texel Rate

The GeForce GTX 295 should be quite a bit (about 245%) better at anisotropic 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 using a high screen resolution is important to you, then the GeForce GTX 295 is a better choice, by far. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
