PCI and AGP expansion slots
PCI continues to be the dominant expansion slot for general hardware on Computers since 1995, when Apple launched the Pentium. As technology advanced, a brand new slot needed to be produced, and AGP was created. Eventually, that wasn't enough for graphics, and also the relaxation from the technology was starting to strain PCI, so PCI Express was created to deal with both issues simultaneously.
Definitions
PCI means Peripheral Component Interconnect. PCI Express has got the additional express put into note the elevated speed and bandwidth over its predecessor.
Bus and Bandwidth
PCI is really a 32-bit, 33MHz interface, delivering a theoretical peak bandwidth of 133MBps (mb per second). PCI Express is really a 32-bit bus utilizing lanes rather than just one speed bus. PCI Express 3. supports 1GBps (gigabyte per second) per lane, as much as 16 lanes
Bus Type
The initial PCI bus is parallel, meaning all products linked to it share the bandwidth, and should alternate utilizing it. PCI Express is really a serial bus, not parallel. Each device includes a point-to-point type of communication, permitting for multiple products to speak simultaneously.
PCI Video Cards
PCI video cards are slow, and employ older technology. Most PCI video cards made today (by 2010) are utilized exclusively for multiple monitor configurations that do not use any three dimensional tasks. No PCI video card uses exterior energy sources.
PCI Express Video Cards
PCI Express video cards are leading edge video cards, sporting the quickest RAM and GPUs (Graphics Processing Models) available. They can handle running demanding three dimensional programs, and have a tendency to want energy from an exterior source.
