Well, Intel is reluctant to contribute to the greater good and focused only on maximizing income ... Read digitaltrends article : "If graphics cards don't need it, what's the point of PCIExpress 4?" that indirectly exposes Intels diversion on PCIe 4.0 .
In the interest of truth and common sense, I like to quote from the article :
"Nvidia RTX 2080 Ti and AMD's Radeon VII require masses of bandwidth to pump out the high frame rates and details that they're capable of. But even these cards don't need what PCIE 3.0 x16 slots offer. So, why is PCIE 4.0 a benefit? Because it means that gamers won't need to run their fastest graphics cards in the fastest configuration.
A 2080 Ti pushes the limits of what a PCIe 3.0 x8 port will allow, just – TechPowerUp's testing proves that. So, on a board with PCIe 3.0, running it in an x16 configuration makes the most sense. But that means the graphics card alone is hogging the all 16 lanes of PCIe."
Well, I'm not an expert on these matters, but has that article got some relevant important observations & foresighted thoughts or not ? ? ?
I'm a diehard Intel-user, but sometimes we must question if profitism or professionalism is on the companys minds ?
Sadly AMD seems to be the real leader now ! :(
