    XB1, 9% upclock on CPU, 6.6% upclock on GPU.

    Swapping out 14gbps ram for 16gbps would be expensive, likely tens of dollars of additional BOM cost.

    The two consoles needs 16 Gbps RAM. The Xbox is more powerful but the bandwidth could be better and not help by the two different memory type.

    For example, PS5 have more bandwidth by CU than Xbox Series X. A PS5 with 512 GB/s or bandwidth would be much better, the same for an Xbox Series X 10 GB 640 GB/ and 6 GB 384 GB/s.

    Not all that technically minded, but i've picked up some of the basics over the years. I guess increasing the bandwidth speed of the current ram would be unfeasible without swapping out completely brand new chips huh..not really sure how these things work.

    I'm wondering how limiting a factor it will be in the end in utilizing the components in the PS5 as a future owner.

    Looking from the outside, i didnt expect MS to have a similar issue with Xbox Series X regarding bandwidth considering how (supposedly)overkill the bandwidth was on the X.

    I guess costs factored into it.

    This is more complicated than that. First 448/36 = 12.44 and 560/52=10.77 but for TMU or RT the global bandwidth is more important for Xbox. After the more you use the 336 gB/s bandwidth the more you lose 560 GB/s. For example if I remember well Zen2 CPU use DDR4 dual channel if the CPU use 51.2 GB/s of memory bandwidht it means the bandwidth diminish and it is 560-51.2 = 508 GB/s. I suppose this CPU will need less bandwidth it will be interesting to see what memory is associated with the equivalent PC CPU.

    And this is only a simplification of the reality.

    So you are saying Knack 3, that will be bad before Knack 4 kills it again

    Can we go on the record to say PS5 supports VRS at this point since it's RDNA 2.0 based? I still find it a bit weird it wasn't mentioned in the presentation by Cerny, is it something he forgot about or do they have their own equivalent solution?

    Hopefully they can create libraries of materials rather than having to commit every unique object to several days of training.

    We have asked follow up questions to SONY about these things and many others regarding PS5. I hope we get a response back.

    It's kind of weird, not talking about vrs, but talking about Primitive shaders, a thing existing since Vega, and working since RDNA 1...

    Unfortunately I suspect no VRS based on the song and dance MS made about it and Sony not even mentioning it (when people are saying how great it is).

    They spent the vast majority of the time on SSD and audio. It’s premature to assume we know everything about the GPU.

    I do t disagree, but IMHO each party talked more about what differentiates them from each other.

    I mean, there shouldn't be anything stopping Sony from getting the VRS right? I know MS has patented their own version but at the very least Sony could just use the one from AMD's RDNA 2.0 right?

    Only thing I would want for PS5 is more bandwidth. Everything else is great.

    With enough uproar/petition from the community maybe we could force Sony to up the bandwidth to over 500 GB/s :).

    MS’s patented version describes an application driven method. They’ve patented the software implementation, not the HW. AMD has their own VRS patent.

    They basically mentioned none of the RDNA2 features. Only that it is an RDNA2 custom GPU. This can be an optimistic sign that they will tell us a lot about it later, or they are pretty much fucked up. If the PS5 is missing so many important features it would make you wonder what went wrong?
    You would expect that since Cerny and AMD knows the roadmap of future graphics that they would implement them at least some important ones.

    II would only worry about this if PS5 is not RDNA2

    Are we sure that RDNA2 has VRS ?
