PCI-E 3.0 vs. PCI-E 4.0: Was bringt PCI-Express 4.0 mit einer RX 5500 XT wirklich?
Welche Vorteile bietet PCI-Express 4.0 wirklich? PCGH hat eine RX 5500 XT getestet und die Ergebnisse sind beeindruckend!

A nice improvement......Now, so many folks told me that PCIE 4.0 would mean nothing for gaming, but I told them that it would mean lots for advanced graphics, more bandwidth is always good.....Just look at the Wolfenstein results to see what I mean....Wolfenstein is a game that streams lots of high quality textures on the fly, it also happens to be using a high quality particle system pushed by the GPU, all the effects are GPU related and high rez, so that requires lots of bandwidth.....see the improvement under PCIE 4.0...
What does this mean for the future? I think this means lots for next gen GPU's and Consoles.....I remember that AMD showed a demo on the raw bandwidth of PCIE 4.0...……...
What people need to know, is how important this is for next gen, next gen is about better lighting, 4k-8k textures, full rez particle systems via the GPU, 60fps, larger worlds where the fidelity stays at a high quality level.....you need bandwidth for that....Moreso is that Raytracing will be a mainstay for next gen GPU's and consoles, the bandwidth you need to do RT not just for Lighting, but for shadows and reflectiosn in game at high rez and quality is indeed tremendous...…...It's also the reason why an HBCC solution is needed on console to stream these assets via a very fast SSD on a PCIE 4.0 bus, you can't have anything bottlenecking the pipeline...….The GPU's will be fast, the bus will be fast, the memory will be fast, that's why I won't be surprised if HBM 3 is a thing for the PS5 or even HBM2 if 3 is not quite ready......HBM 2 spec was actually upgraded months ago, it now supports 2.4GB/s per pin and also increased it's design from 8Gb per layer to 16Gb per layer definition for higher density solutions...…Personally, I'd love to see HBM3 on PS5 with it's efficiency and raw bandwidth, but perhaps that a talk for PCIE 5.0 + HBM 3 in the future.....
In any case, more is always better when it comes to bandwidth, it's only logical that the next step in GPU's and consoles require high speed buses to push the envelope with high end graphics with Raytracing in tow...….So when I read the next gen hardware thread and people try to downplay console hardware to 8-9TF or GTX 1080 like performance, I have to sigh, because if we truly want a new gen experience, we have to do way better than a GTX 1080......There's no way you are getting 4k 30/60fps with RT on such tepid GTX class solutions.....Next gen consoles will easily outclass the 5700XT with RT on top.….
