GeForce GTX 295 vs GeForce GTX 480

Intro

The GeForce GTX 295 has core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.

Compare those specifications to the GeForce GTX 480, which has a GPU core clock speed of 700 MHz, and 1536 MB of GDDR5 memory set to run at 924 MHz through a 384-bit bus. It also is made up of 480 Stream Processors, 60 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 480 250 Watts
GeForce GTX 295 289 Watts
Difference: 39 Watts (16%)

Memory Bandwidth

In theory, the GeForce GTX 295 should be much faster than the GeForce GTX 480 in general. (explain)

GeForce GTX 295 223776 MB/sec
GeForce GTX 480 177408 MB/sec
Difference: 46368 (26%)

Texel Rate

The GeForce GTX 295 is quite a bit (about 119%) better at AF than the GeForce GTX 480. (explain)

GeForce GTX 295 92160 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 50160 (119%)

Pixel Rate

The GeForce GTX 480 should be a little bit (more or less 4%) more effective at AA than the GeForce GTX 295, and should be able to handle higher screen resolutions better. (explain)

GeForce GTX 480 33600 Mpixels/sec
GeForce GTX 295 32256 Mpixels/sec
Difference: 1344 (4%)

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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

GeForce GTX 295 will be better by performance but it won't make a huge difference , GTX 480 is newer

No matter how great performance gtx 295 does it lags the direct x 11 effects which can be given by gtx 480
