    It’s pretty unlikely to see this on any GPU that utilizes 16 PCIe lanes. Even if it doesn’t actually affect performance, it’s significantly more complicated than what ASUS is doing here. They’re basically just using unused lanes, and even then it’s only going to work on certain motherboards. Pretty niche.

      throwing away bandwidth is pretty dumb

      maybe we will see gpus being plugged into pcie 5.0 x4 slots in the future.and more x4 slots showing up in motherboards.

      But if gpus continue to take up full 16x slots and not use the bandwidth, that’s just going to hurt the hurt the already horrible amount of pcie lanes we get on consumer platforms

        throwing away bandwidth is pretty dumb

        I mean… it’s fine. You’re not maxing out the bandwidth on every single connection in your PC 24/7. No one is.

        I don’t know why you think this is dumb.

        no gpu needs 16 lanes of PCIE 5.0. And likely won’t for several generations

        Sure… but high end GPUs do see a significant difference between PCIe 3.0 16x and PCIe 4.0 16x. You know what’s the equivalent of PCIe 3.0 16x? PCIe 4.0 8x. Not everyone has PCIe 5.0 today, in fact most don’t. Many people still have PCIe 4.0 that are buying high end GPUs. I’m one such person, I have a 4090 with a PCIe 4.0 AM4 motherboard.

        You can’t make a GPU that uses 16 lanes only on PCIe 4.0 but drops down to 8 lanes on PCIe 5.0. That’s not how it works. And considering most people today don’t yet have PCIe 5.0, it’s very unlikely GPU manufacturers would be willing to create 8x only versions that are only meant to be used on PCIe 5.0 motherboards. The only reason Asus did this with the 4060ti is because that GPU is already an 8x GPU.

        maybe we will see gpus being plugged into pcie 5.0 x4 slots in the future.and more x4 slots showing up in motherboards.

        We absolutely will not.

        But if gpus continue to take up full 16x slots and not use the bandwidth,

        Again… they do use the bandwidth on older versions of PCIe. Not everyone is on the newest platform. You will always have a portion of the market pairing newer GPUs with older motherboards.

        By the time GPUs actually start to see a benefit on PCIe 5.0, we will have PCIe 6.0 and you’ll be making the same argument… but not everyone will be on PCIe 6.0 yet.

        that’s just going to hurt the hurt the already horrible amount of pcie lanes we get on consumer platforms

        This hasn’t been a real problem in years. Where do you think you’re being bottlenecked in terms of lanes on a consumer platform? What do you think you need them for?
