In August, Gigabyte made a claim that baffled at least MSI, that scores of its motherboards are Ready for Native PCIe Gen. 3. Along with the likes of ASRock, MSI was one of the first with motherboards featuring PCI-Express 3.0 slots, the company took the pains to educate buyers what PCI-E 3.0 is, and how to spot a motherboard that features it. MSI thinks that Gigabyte made a factual blunder bordering misinformation by claiming that as many as 40 of its motherboards are "Ready for Native PCIe Gen. 3." MSI decided to put its engineering and PR team to build a technically-sound presentation rebutting Gigabyte's claims.More slides, details follow.

MSI begins by explaining that PCIe support isn't as easy as laying a wire between the CPU and the slot. It needs specifications-compliant lane switches and electrical components, and that you can't count on certain Gigabytes for future-proofing.MSI did some PCI-Express electrical testing using a 22 nm Ivy Bridge processor sample.MSI claims that apart from the G1.Sniper 2, none of Gigabyte's so-called "Ready for Native PCIe Gen. 3" motherboards are what the badge claims to be, and that the badge is extremely misleading to buyers. Time to refill the popcorn bowl.
