GeForce GTX 465 vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 465 uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM works at a frequency of 802 MHz on this specific card. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.

Compare those specifications to the GeForce GTX 560 Ti 448, which features GPU core speed of 732 MHz, and 1280 MB of GDDR5 memory running at 900 MHz through a 320-bit bus. It also is made up of 448 SPUs, 56 TAUs, and 40 ROPs.

GeForce GTX 560 Ti 448 144000 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 41408 (40%)

Texel Rate

The GeForce GTX 560 Ti 448 should be quite a bit (approximately 53%) more effective at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 560 Ti 448 40992 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 14284 (53%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be much (about 51%) more effective at AA than the GeForce GTX 465, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti 448 29280 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 9856 (51%)

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 max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed 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 the texel rate, 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 maximum number of pixels that 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
