The RTX 3080 cares about having a bit more bandwidth than PCIe 3.0 x16, but the difference isn't much. As mentioned earlier, a purchase of a Ryzen 5 5600 and selling your 5600G might be worth it. But the difference in performance is small.

Hello,

I am planning for buying GPU (Either RTX 3070/4070), and I heard the rumor that RTX 4070 much better than the RTX 3070. But the problem is , since later RTX 4070 have PCIe Gen 5.0, I wonder if the GPU will bottleneck very much with the PCIe 3.0. Because as you know , Ryzen 5 5600G only support 16 Lanes PCIe Gen 3.0 for the GPU. Is this cause a huge performance drop because of PCIe generations?

 

My usage mainly for Deep Learning Computes. Yes I will game on it , but not so much.

I dont think you should be worrying about the 4000 series just yet lol

Ah gotcha, But What about PCIe Gen 4.0. Is the current GPU are available to use all the bandwidth or there will be still a headroom for PCIe 3.0 for the next gen GPU?

Do you already have the 5600G?

Corps aren't your friends. "Bottleneck calculators" are BS. Only suckers buy based on brand. It's your PC, do what makes you happy.  If your build meets your needs, you don't need anyone else to "rate" it for you. And talking about being part of a "master race" is cringe. Watch this space for further truths people need to hear.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad
