Correct me if I'm wrong, but...

Trust me, this will turn into a gaming thread, not a Tech thread..

If i want my Gpu to run at 4x16, i will need my SSD to be Gen5 ? because if i put the SSD in as a Gen4, it takes the 16 from the PCIe ...

This was not an issue on my last build, but I've gone bananas on this one

My quick answer is “no”, but I’ll want more info. What is the exact model of both your gpu and motherboard?

ASUS Prime B760-PLUS Intel B760

I am pretty sure where you slot your SSD on the mobo can potentially impact GPU performance, but a 4060 GPU shouldn't even come close to saturating a gen 4 PCIE lanes even if the SSD is taking 8 of them away.

This is the chipset block diagram, but I'll actually defer to someone who knows Intel chipsets better than I do, because it's kinda fricky:

From the looks of your board, your top GPU slot is PCIE 5 x16. Your SSD slots are 4 x 4. What you are capable of depends on what Gen your CPU is. Gen 11 Intel has 20 gen 4 lanes but Gen 12 Intel has 16 gen 5 and 4 gen 4.

Your GPU will not be using the bandwidth available for the Gen 5x16 lanes as no GPU uses Gen 5 yet. You can certainly put a Gen 5 ssd, but you'll be wasting money and it will not hit Gen 5 speeds. Just get a Gen 4 ssd and both GPU and SSD should be fine.

PCI Express Revision 5.0 and 4.0
PCI Express Configurations ‡ Up to 1x16+4, 2x8+4
Max # of PCI Express Lanes 20

so, based on that math, GPU takes 16 and an SSD can take 4..I think in my older machine, i overcrowded with SSD and it took away from the GPU..

this part, is all new to me

That is completely possible.

However, PCIE 5.0 is faster than 4.0, IMO, your 4060ti won't notice if it was sharing 4 lanes with your 4.0x4 SSD. But in your current MB, the SSD will have its own 4 lanes. Now, any subsequent SSDs installed will share the 4 lanes but your GPU should be unaffected.

And to expound on this: I doubt a 4060ti would saturate 16 lanes of PCIe Gen 3, to say nothing of Gen 4, to say nothing of Gen 5.

I actually went with an ARC A770 and its running circles around anything i've ever used before

Just eyeballing a GPU tier chart, the A770 is basically on par with a 2070 and a 6600xt, so depending on what you had before, that tracks.

son is running an 8Gb 6600, so makes sense...

don't trust everything you read though, this card can hold its own vs name brands

Yes to the latter, but not so much to the former. When the Arc series was first released, Intel’s drivers were terrible. Just awful. The hardware performed far worse than it “should have” based on the tech. But kudos to Intel, they’ve stayed on it instead of abandoning it and, by all accounts, the drivers have gotten much, much better. Now the Arc cards can be a sneaky value in the low to mid range, and people are actually interested to see what Intel puts out for its next gen.

The 20 pcie lanes(AMD has 24) and not a dead platform is why I chose AMD. I can add another SSD and not cut my GPU in half later on down the road in a several years if I decide to get a high-end one.

honestly, familiarity kept me on the intel train this build..

I have had ZERO issues with my sons AMD card on his intel board, i just didnt have time to research AMD for my build and i needed to be out there spreading Democracy ASAP

Intel LGA1700 being dead is also why I went with AM5. But LGA1700 will be useful for years. Its just the last PC I built, I went with LGA1200 right when 12th gen Intel came out and I regretted it. I didn't want to wait in 15th gen Intel.

AM5 actually has either 36 or 44 total PCIE lanes, depending on your board. X670E has 24 usable 5.0 lanes.

There should be no issues with sharing lanes until PCIe 5.0 is being used for both GPU and SSD.

Ya, my SSD is pcie 4 atm, but will want 2 pcie 5 down the road. I built this rig to last me to 2030(hopefully).

What board do you have that has 2 PCIe 5x4 SSD slots? I have the X670E Tomahawk and it has 1 - 5x4 and 3 - 4x4s.

Looking at it, and it only appears to have one pcie 5 slot(for nvme).

I was thinking between the asus strix and tuf(Ichose this) and it appears I dun goofed on the pcie 5 slot. And the extra pcie 5 slot was what I was wanting. The strix had 2.

O well, at least it's not a dead platform.

Honestly, PCIe 5 is overkill for gaming (on the SSD). Those speeds will be useful for file transfers but PCIe 4, hell, even PCIe3 is great for gaming.

Having PCie 5 for your GPU slot is where the bang for the buck comes as to longevity. When GPU makers start actual making 5.0 cards, then I think thats where it will be useful.
