GeForce GTX 980 vs Geforce GTX 670

Intro

The GeForce GTX 980 makes use of a 28 nm design. nVidia has set the core frequency at 1126 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the Geforce GTX 670, which comes with core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs as well as 112 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core 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 that the graphics card could possibly record to the 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
