Ryzen 7 5700 PCIe 4.0

I have recently bought a Ryzen 7 5700. I read from sources online that this CPU supports only PCIe 3.0. However, in the product's box, it says it is PCIe 4.0.

 

Is that just a print mistake or did I get lucky?

Hard to say, Fallenmcdc. Some specifications say 3.0 and some say 4.0 on the AMD web site. Also there is an AMD Radeon RX 5700 Video card which just confuses us more. Please contact AMD here. Enjoy, John.

That's exactly the table I had seen, and the reason why I was confused by the label informing it is PCIe 4.0

Hello as i read on internet it ineed support PCIE 4.0(if motherboard support it ofc) also worth Mention Ryzen 7 5700X also supports Pcie 4.0 which is just 5700 without x but "unlocked" cpu u can easly bring performance on par with version X just by setting motherboard power limits. 

 

1 x PCI Express x16 slot (PCIEX16), integrated in the CPU
  1. AMD Ryzen™ 5000 Series* and Ryzen™ 3000 Series Processors support PCIe 4.0 x16 mode
    * Actual support may vary by AMD CPU's specification.
  2. AMD Ryzen™ Ryzen™ 5000 G-Series and Ryzen™ 4000 G-Series Processors support PCIe 3.0 x16 mode

 

I can ask my friend maybe tommorow he is to check what pcie express version he got there

The Ryzen 5700 and 5700G processors are based on the Cezanne die which only supports PCIe 3.0 - the difference is the 5700G has integrated graphics and the 5700 does not.

The Ryzen 5700X uses Vermeer architecture which does support PCIe 4.0

Ryzen R7 5700X | B550 Gaming X | 2x16GB G.Skill 3600 | Radeon RX 7900XT
Ryzen R7 5700G | B550 Gaming X | 2x8GB G.Skill 4000 | Radeon Vega 8 IGP
Ryzen R5 5600 | B550 Gaming Edge | 4x8GB G.Skill 3600 | Radeon RX 6800XT

Might be like this but then why its PCIE 4.0 stated? i check other CPUS brand new they also state PCIE 4.0 in specs. It can be AMD relase refreshed version of 5700?

Here are the specs @ AMD that @misterj posted a screenshot of

https://www.amd.com/en/products/specifications/processors.html

Search on 5700, scroll to the right, the only 5700 processors listed that are PCIe 4.0 are the 5700X and 5700X3D which are Vermeer. Processors based on Cezanne or Lucienne only support PCIe 3.0

You may have a counterfeit product, here is how you can check authenticity

Ryzen R5 5600 | B550 Gaming Edge | 4x8GB G.Skill 3600 | Radeon RX 6800XT

I thoroughly checked the authenticity of the product following the link, and everything is in order. Due to that I am disregarding the "4.0 PCIe" on the label as a print error.

Please post a screenshot of CPU-Z once you have that processor in a system, it will be interesting to see what it indicates.
