Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor upgrades.
Socket 478 was intended to be the replacement for Socket 423, a Willamette-based processor socket which was on the market for only a short time. This was the last Intel desktop socket to use a pin grid array interface. All later Intel desktop sockets use a land grid array interface. Socket 478 was phased out with the launch of LGA 775 in 2004.
[2]: 12 [8] Buses exposed through the M.2 connector include PCI Express (PCIe) 3.0 and newer, Serial ATA (SATA) 3.0 and USB 3.0; all these standards are backward compatible. The M.2 specification provides up to four PCI Express lanes and one logical SATA 3.0 (6 Gbit/s) port, and exposes them through the same connector so both PCI Express and ...
On 29 November 2011, PCI-SIG preliminarily announced PCI Express 4.0, [71] providing a 16 GT/s bit rate that doubles the bandwidth provided by PCI Express 3.0 to 31.5 GB/s in each direction for a 16-lane configuration, while maintaining backward and forward compatibility in both software support and used mechanical interface.

Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
Each of the X99's SATA Express ports requires two PCI Express 2.0 lanes provided by the chipset, while the M.2 slots can use either two 2.0 lanes from the chipset itself, or up to four 3.0 lanes taken directly from the LGA 2011-v3 CPU. As a result, the X99 provides bandwidths of up to 3.94 GB/s for connected PCI Express storage devices.
2.0, 100 MT/s PCI Express 2.0 8 × 1 ports, single 32-bit 33 MHz PCI bus, DMI for processor 4 × USB 3.0 + 14 × USB 2.0, 2 × SATA 1.5/3/6 Gbit/s + 4 × SATA 1.5/3 Gbit/s, Integrated LAN, Integrated Graphics, Intel Anti-Theft Technology, Active Management Technology 8.0
The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
