GeForce GTX 465 vs Radeon R7 260X

Intro

The GeForce GTX 465 has a GPU core speed of 607 MHz, and the 1024 MB of GDDR5 RAM is set to run at 802 MHz through a 256-bit bus. It also is comprised of 352 Stream Processors, 44 TAUs, and 32 Raster Operation Units.

Compare those specs to the Radeon R7 260X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM runs at a frequency of 1625 MHz on this particular model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
