GeForce GTX 295 vs GeForce GTX 570

Intro

The GeForce GTX 295 makes use of a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

Compare all that to the GeForce GTX 570, which has a clock speed of 732 MHz and a GDDR5 memory speed of 950 MHz. It also features a 320-bit memory bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 570 219 Watts
GeForce GTX 295 289 Watts
Difference: 70 Watts (32%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 will be 47% quicker than the GeForce GTX 570 in general, due to its greater data rate. (explain)

GeForce GTX 295 223776 MB/sec
GeForce GTX 570 152000 MB/sec
Difference: 71776 (47%)

Texel Rate

The GeForce GTX 295 will be a lot (more or less 110%) better at texture filtering than the GeForce GTX 570. (explain)

GeForce GTX 295 92160 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 48240 (110%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 295 is the winner, but only just. (explain)

GeForce GTX 295 32256 Mpixels/sec
GeForce GTX 570 29280 Mpixels/sec
Difference: 2976 (10%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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 bandwidth is, the lower the potential to get to the max fill rate.

site is very good and continues with the work

you really shoud and more importantly... NEED to update this comparison with REAL TIME results... "Theory" is a bullshit waste of time and what's worse is that both cards have been out for some time... LAZY!
