GeForce GTX 465 vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 465 has a clock speed of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is made up of 352 SPUs, 44 Texture Address Units, and 32 ROPs.

Compare those specs to the GeForce GTX 560 Ti 448, which uses a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 memory runs at a speed of 900 MHz on this specific model. It features 448 SPUs as well as 56 TAUs and 40 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
