GeForce GTX 465 vs GeForce GTX 980

Intro

The GeForce GTX 465 comes with a core clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is made up of 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Compare those specifications to the GeForce GTX 980, which makes use of a 28 nm design. nVidia has clocked the core speed at 1126 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific model. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must 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, HDR 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 figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
