The way Cerny was talking about it and the coherency engines seemed to be about smart cache line invalidation and not Error recovery / data integrity which is what ECC is for with a wide and high frequency GDDR6 channel like XSX has. Although yes in literature we have scrubbers as a way to help with error correction.
It's an interesting distinction nonetheless. And I'd like to see how it plays out in practice tbh.
actually it can, it just depends on the workload.
ECC memory tends to be more expensive, and I don't see why it'd be needed with just 16GBs of ram and non datacenter workloads. It might simply be there since the same h/w is going into servers apparently.
Yes ECC goes for more, but there's a reason for it. And you're also right the main reason is because XSX is also going into datacenters/server blades, but it's a side benefit the consumer console will be able to enjoy.
Probably more interesting is that despite being ECC, it's still very fast. Usually ECC memory runs slower than the non-ECC equivalent, just look to ECC and non-ECC DDR3/DDR4 modules for example. So essentially it seems like a decision that will benefit the system in both environments.
You know what's funny? You just quoted a post that has to do with Xbox's advantage in GPU performance, but some numbers are not confirmed.
I never said the numbers were all confirmed, and did not speculate on the basis as if the numbers were all confirmed. I just touched on how NX Gamer's video mentioned things regarding the role of those parts of the GPU. Nice try, but you failed.
The numbered have not been confirmed, but you overlooked that and pointed out that's what NX Gamer said in this video. You're judging based off of numbers alone.
...and the context of the numbers. Remember when I mentioned that earlier? Seems not. Again, I never quoted the post as confirmation of unconfirmed numbers, just the fact it brought up aspects of the GPU that are also highly influential in overall performance besides clock speeds. That was the point of me even quoting it.
Yet Mark Cerny mentions streaming speed of his SSD with numbers, you become skeptical. You never gave a reason why you doubt him with the numbers he provided when it comes to pure SSD speed.
Lol what? I've already mentioned my reasons MULTIPLE times across other posts in other threads. I shouldn't need to compile them again just to satiate your peace of mind. But if you'd like a basic rundown, fine, here are some of the reasons:
-NAND module bandwidth
-NAND module latency
-NAND module random access on first byte
-NAND module random access on first block
-NAND module general random access
-NAND module page size
-NAND module block size
-SRAM cache size
-long-term NAND module performance (wear-leveling)
-heat dissipation and whether high SSD power draw could factor as an impact into variable power reallocation in the system
-are the given speeds locked (consistent) or peak (goes with the other question above; could power reduction in the system cause a speed drop in the SSD operations and if so, by how much?)
....just for example. And all but the last two questions there ALSO apply to XSX's SSD, but you can keep pretending I"m only being critical of aspects of PS5's SSD if you want.
It's not hard to tell when someone is bias.
You know what, you're right. I do have a bias. It's a bias for evening out the discussion. I have a legitimate interest in
both next-gen consoles, a
genuine one, but there's a strong contingent of borderline toxic PS5 bias around. What does that mean? Well, it means going beyond mere preference (which is perfectly fine), and pushing into an angle to basically parade for one system by pecking away and downplaying the other. Whether that's blatantly obvious, or through subtlety, or through a given tone in persistent patterns of posting, or a mixture of the three, IMO it taints the well of discussion.
And let us be perfectly clear here; yes there's a small handful of Xbox fans around who have been doing some of the same, but this is the kicker: the number of PS/Sony fans doing this is magnitudes more, because there's this thing called scale-in-numbers, and with ratios remaining equal, since there are many more only-PS/Sony fans around, that invariably gives a larger pool of those who could be labeled toxic (i.e in the vein of doing what I mentioned above). If things were reversed, you'd have the inverse situation, but that isn't the case.
That hurts to say, too, because I was one of the guys being very optimistic/lenient in the Next-Gen speculation thread around the time the Github leak and testing data was coming out. You never saw me jump headfirst on #TeamGithub; I just kept that stuff as a possibility of being onto something. I made
this thread shortly after Road to PS5 going over the two systems, and kept things as fair as I could've given when it was made (an updated version may be in order at some point). I've disagreed with people who have been insisting the SSDs are for nothing more than quicker load times, too, so....
...my bias, right? Yeah I know what you were trying to imply, and right now I might be more inclined to offer speculative clarification on XSX rather than PS5 given the state of overall discussion the past couple or so weeks throughout multiple threads, but that all ties back to evening out the discussion. If there was a massive presence of PS5 misinformation and few people actually trying to parse out the truth from the BS and cut down on FUD, I'd be doing this with PS5 instead. But they have Jason Scheirer, Sony's own 1st-party devs, multiple YT tech and gaming channels, and
many people on forums such as yourself, doing a fine enough job of that already.
You can try saying there's an irony to my method since such a thing could be conflated as "sticking up for the little guy", and MS is neither a person nor a "little guy" in the grand scheme of things at all, but it's not a stretch to say Xbox is the underdog in this upcoming generation. It's the one that has more to prove to win back votes of confidence, so on some level of the skepticism towards what they've shown and announced is perhaps warranted. But that indirectly creates the type of scenario where I just feel a desire to try bringing back some nuance and balance to the discussion, because we've got too many other examples in other aspects of entertainment where that has fallen to the wayside and led to complete trainwrecks in discussions there because everything becomes very binary (as in exclusively-"us" or exclusively-"them") and partisan, and the fun drains away with it.
I don't want that happening with gaming any more than it already has, and certainly not when it comes to next-gen console speculation/discussion.
