GeForce GTX 460 1GB vs GeForce GTX 465

Intro

The GeForce GTX 460 1GB has a core clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the GeForce GTX 465, which comes with core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs along with 44 Texture Address Units and 32 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 in one second. This is worked out by multiplying the total texture units 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
