<P> Intel X99, codenamed "Wellsburg", is a Platform Controller Hub (PCH) designed and manufactured by Intel, targeted at the high - end high - end desktop (HEDT or enthusiast) segment of the Intel product lineup . The X99 chipset supports both Intel Core i7 Extreme and Intel Xeon E5 - 16xx v3 and E5 - 26xx v3 processors, which belong to the Haswell - E and Haswell - EP variants of the Haswell microarchitecture, respectively . All supported processors use the LGA 2011 - v3 socket . </P> <P> The X99 chipset was released in late August 2014, while the supported processors were released in late August 2014 (Haswell - E) and early September 2014 (Haswell - EP). </P> <P> The X99 chipset uses a Direct Media Interface (DMI) 2.0 × 4 link for the connection between the processor and itself; that way, a total bandwidth of 20 Gbit / s is available to all connectivity options provided by the chipset . Up to eight PCI Express 2.0 lanes are provided by the X99 chipset, with speeds of up to 5 Gbit / s per lane and a possibility to configure these lanes into × 1, × 2 and × 4 links . Additionally, the X99 chipset supports a configurable layout of the PCI Express 3.0 lanes provided by the processor, which may be bifurcated into up to two × 16 links and one × 8 link, or into up to five × 8 links (the total number of available PCI Express 3.0 lanes depends on the used processor). </P> <P> Two Serial ATA (SATA) 3.0 controllers are integrated into the X99 chipset, providing a total of up to ten ports for storage devices and supporting speeds of up to 6 Gbit / s per port, with hardware support for the Advanced Host Controller Interface (AHCI) logical interface . Each SATA port may be enabled or disabled as needed . Six SATA ports provided by the first controller may be configured for Rapid Storage Technology (RST) 13.1, which supports RAID 0, 1, 5 and 10 levels; additionally, Smart Response Technology (SRT) disk caching allows the creation of hybrid volumes . </P>

Do pci express 3.0 graphics adapters connect directly to the processor or to the x99 chipset
