Slow down and read the comments. There's a half dozen discussing that exact GPU. And anyways, I'm in complete agreement, writing articles about what PCIe 6 is gonna be like is no less worthless than throwing a "going away" planning a party for the people going to colonize mars.You're only about 2.5 years late to the party! LOL
No one is wondering how an RX 6600 XT will perform on a PCIe 7.0 connection. What they're wondering is when we'll have PCIe 7.0 (consumer) platforms and hardware, and whether there will be a performance benefit. You can tell how "bottlenecked" GPUs are by the fact that Nvidia is only how moving to PCIe 5.0 with the 50-series, even though that's been ready for over three years.
