GeForce 9800 GTX+ vs GeForce GTX 860M

Intro

The GeForce 9800 GTX+ comes with a core clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.

Compare all that to the GeForce GTX 860M, which comes with core speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
