GeForce GTX 465 vs GeForce GTX 560

Intro

The GeForce GTX 465 features core clock 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.

Compare all that to the GeForce GTX 560, which features a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 150 Watts
GeForce GTX 465 200 Watts
Difference: 50 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 560 is 25% faster than the GeForce GTX 465 overall, due to its higher bandwidth. (explain)

GeForce GTX 560 128128 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 25536 (25%)

Texel Rate

The GeForce GTX 560 is quite a bit (more or less 70%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 560 45360 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 18652 (70%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 465, and very much so. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 6496 (33%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
