Peripheral Component Interconnect Special Interest Group (PCI-SIG) has announced that the PCIe connection slot, used by most graphics cards of today, is due an enhancement release later this year, to be called PCIe 4.0. The PCIe 4.0 connection slot will reportedly bring double the performance capability of today's current PCIe 3.0, which is the name of the connection slot being used by us gamers at the moment.
The interconnect bandwidth will double from 8 gigatransfers per second in PCIe 3.0 to 16 GT/s PCIe 4.0. The new standard could be revolutionary in terms of data transfer between different parts of a computer and more.
PCI Express is a high-speed bus or connector which provides data transfer between components of a computer such as an external GPU of a laptop or storage devices such as SSDs or memory cards. The standard being used nowadays is PCIe 3.0 which gives a 32GB/s data transfer rate, whereas the upcoming standard will provide 64GB/s speed. Doubling the transfer speed in just three years.
So this boils down to the new PCIe 4.0 improvements could mean graphics cards have up to double the data transfer limit, thus removing a possible bottleneck and freeing up their potential gaming performance.
To continue this trend it is said that PCIe 5.0 will be arriving in 2019 and promises an even more astonishing bandwidth of 128GB/s. The leap could prove beneficial especially for multi-GPU setups such as SLI and Crossfire. We may not need a separate connector for multi-GPU setups in the future, but likewise this also means that a single card solution will be capable of more data transfer. Furthermore, it will have the support of 400Gb ethernet connections for fast uploads and downloads. AAA games will only need a second or two tops in order to be downloaded.
Are you excited about the new standard? What possible benefits do you think PCIe 4.0 and 5.0 will bring? Let us know!
