GeForce GTX 295 vs GeForce GTX 465

Intro

The GeForce GTX 295 makes use of a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this particular model. It features 240 SPUs along with 80 TAUs and 28 Rasterization Operator Units.

Compare all that to the GeForce GTX 465, which comes with a GPU core clock speed of 607 MHz, and 1024 MB of GDDR5 memory set to run at 802 MHz through a 256-bit bus. It also is comprised of 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 295 is 118% faster than the GeForce GTX 465 overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 295 should be a lot (more or less 245%) faster with regards to AF than the GeForce GTX 465. (explain)

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

Pixel Rate

The GeForce GTX 295 is quite a bit (about 66%) more effective at AA than the GeForce GTX 465, and also should be capable of handling higher resolutions more effectively. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
