[SOLVED] Which would be faster

[ManOfArc]

Kind of an off-the-wall hypothetical question, I know. But just curious about the performance potential of PCIe 4.0 over PCIe 3.0
On say a Ryzen 5 5600 XT / Asrock B550M Pro4 platform w/16GB DDR4 3600, which GPU would be faster gaming @ 1440p? ( basically across most all AAA games in general)

1. RTX 2070 @ PCIe 3.0
2. RX 5600 XT @ PCIe 4.0

My guess.....the 2070 wins.

The 2070 is the better card, neither are capable of saturating PCI-E 3.0.

2070 at rank 25.
5600XT at rank 30.

FYI, it's the 55xx and 65xx that are heavily affected by lane speed, not the 5600XT.
Steve over at Hardware Unboxed has already examined this.

Is there somewhere in that hierarchy chart that says whether the cards were tested at PCIe 3.0 or 4.0?

Your worrying about nothing, it shouldn't even factor into your purchasing decision. It will make absolutely zero difference. Here's testing on the 3080 on PCI-E 3.0 vs 4.0:

PCIe 4.0 vs. PCIe 3.0 GPU Benchmark

With the launch of the new GeForce 30 series, PCI Express 4.0 performance has come up into the discussion. To find out exactly what we're talking about,...

The 3080 is much more powerful than either of those cards, pay close attention to PCI-E 3.0 x16 vs 4.0 x16.

No worries. Actually, I already assumed as much. My point was wondering if PCIe 4.0 would allow the RX 5600 XT to gain anything, or maybe even catch up with the normally faster 2070.

No it wont, and even if it did it doesn't matter. The 2070 also has DLSS which would only extend it's performance lead over the 5600 XT.

May I ask if this was just curiosity or were you looking to purchase a new GPU?

Curiosity about the benefits of PCIe 4.0 besides faster storage throughput. I figured I could spend hours researching or just come here and ask the experts. Still learning, ya know.

Fair enough, no it's really just storage right now, will be beneficial for Microsoft Direct Storage when that becomes available. Some budget AMD GPU's only have 4 or 8 lanes therefore run better on PCI-E 4. In bandwidth terms though the next generation will likely benefit more.
