MSI Calls Out Gigabyte for "Not True PCIe 3.0"
MSI calls out Gigabyte on its claims of having 40 PCIe Gen3 ready motherboards and wants to set the story straight.
MSI put together a presentation to detail information on what it feels is a true PCIe Gen3 motherboard. MSI is pointing out that, from its view, Gigabyte's claim on having 40 PCIe Gen3 boards isn't true.
MSI shows that its motherboards utilize Pericom 34xx (Gen3) switch chips, whereas Gigabyte utilizes Pericom 24xx (Gen2) switch chips. To fully utilize PCIe Gen3, all components are required to be Gen3 compliant to operate at 32 GB/s (CPU, PCIe Slot and GPU).
MSI said that it did some PCI-Express electrical testing using a 22 nm Ivy Bridge processor sample to show the bandwidth seen on Gigabyte's P67A-UD4-B3 and MSI's MSI Z68A-GD65 (G3).
MSI states through their review that the only true PCIe Gen3 ready Gigabyte motherboard is the G1.Sniper 2.

internetlad Either way i've never owned a gigabyte product, I've felt they're third tier products at a second tier price. I've been running an Asus board for years and it hasn't caused me problems yet!Reply -
