DigitalFoundry: X1 memory performance improved for production console/ESRAM 192 GB/s)

And they downclocked the ESRAM, but make the machine faster.
Magic... the power of the "theorethic" cloud?
Right... PR vaporware. Period.

If you're so confident in your math, bet your account on it that this is gpu is now 750 mhz.

CBOAT never said anything about downclocking.
CBOAT admitted PoP was a mistake/was pulled.
ME2 was at EA's conference.
CBOAT never said PS4 wouldn't have a paywall.
MS clearly removed their DRM on short notice, so we'll never know if the DRM was going to get worse.
So, no.
Edit: I see many others already replied basically the same thing, oh well.

The "clock" is dependent on the thing that's accessing it. In this case, the GPU.
It was supposed to be 204 Gb/sec before ?

Has a 50Mhz downclock been rumoured before? If not then aren't you just re-aligning facts/figures to meet your agenda? Sorta like truthers.
Doesn't this all hinge on whether or not DF's information is correct?
He and others are assuming that there is some truth to this 192GB/s figure.

With the logic going into this thread yes but gaf told me its was fake and esram doesn't work like this unless it confirms an downclock.
if all we know about power is true, then difference will be easy to spot in multiplatform games, not just fps but better graphics/effects, etc.

You're literally the last poster who should be saying that.
Oh, I see.. Missed that number before, thanks!
Sound like MS engineers found out about the bidirectional part?, didn't they design the thing?

Being DF said single read or write is 102 still people are choosing one number that fits their math assumption but ignoring the rest. First sign to me that people are stretching.

Yeah a downclock was talked about in the same thread as the #TRUEFACT thread. A few of the GAF insiders said they "heard" that there may have been a downclock to get yields up. Nothing really confirmed though.

Oops =P
The rumor from Thuway was 100-300. Which would have been nuts if true.
The article is saying that there some extra resources that are available in a different interval. At best every X time in the processing pipeline you have something extra to play around with. The math people are posting in this thread is based on the interval that they know, which is that you perform one read/write per clock edge. We already know that a read and a write are performed each clock. The article isn't talking about that. The problem the article gives is that every X read/write edge you get an extra one or something in the edge.
IMO the math that people are posting has nothing to do with the problem I am picking up from the article.
Ban bets are not allowed anymore afaik but if a mod allows it I'll do it as long as you also bet yours that it's 800 mhz. Btw I'm not the one acting like an expert judging others from my pedestal, all I did is use some common sense and basic math.
I'm mainly a PC gamer that buys all consoles. The two GPUs in the end products simply aren't massively different in the world of gaming GPUs.
Possibly, but unlikely when it comes to 3rd party. They'll most likely aim for 30 or 60. Twenty FPS is probably an extreme example.
Why do you think the PS4 is crap? I think it'll be just fine. If you feel it is, that's your choice.
It has be done before the chip has been designed. You will need a asynchronous bridge between the GPU and Memory to clock them independently. The bridge will buffer requests, which will add latency.
Clocking them independently only helps when the GPU is operating on cached data. Most of the time it will stall and wait for the data to arrive from eSRAM.

Yes I know of the downclock rumour, never heard of 50Mhz specifically. Such a specific rumour would need to exist to give this any weight at all, otherwise it's just agenda-driven speculation.

I guess you are free to bring up arguments and engage in the discussion.
So you are disregarding the previous rumors because they did not specify the exact same figure?
We are listening
Why is a specific number necessary to be rumored?
Do you understand the math that is being done here or do you think the values are chosen at random to make the Xbox One look bad?
I feel the posts about the downclock in this thread are very clear and specific with how they arrived at that conclusion. They are based on the numbers that seem to come from the source of the article and aren't the part that is editorialized.
I'd suggest you bet against it beeing 192GB/s peak performance @ 800MHz... (This combination makes little sense on the informations we have gotten so far)

I see forwarding getting called a few times on beyond3D.
It sounds like coalesced read and writes.
Dont worry about it. Proelites maths have been questionable for a while. I am pretty sure he was the guy calling the the GPU in the "One" more powerful that the PS4's (I think he was saying it was 2.5TF if I remember correctly)
Besides, he was relegated to junior for a reason
Seriously, you're going to argue with him on a 5% difference?

I see someone without inside information trying to debunk someone with inside information based on essentially nothing.

Its hilarious how the day after Cerny talks about XB1's eSRAM this article is put out and the math doesnt quite add up.

Wasn't that Reiko and MisterXteam or something like that.
Im pretty sure that talk had nothing to do with it. While interesting it was more a trip down memory lane.
What's your point? They're pretty much admitting that they're adding read/write to give us theoretical bullshit numbers which was the basic premise of my argument. Even if their PR is somehow true the downclocking is still real.
But it is based on the number from the source in the article.

Lemme get this straight. Yesterday , Cerny talks very precisely about the high system bandwidth of the PS4, then out of nowhere Microsoft responds the next day by saying their bandwidth is somehow like 80 percent bigger that they expected and thus similar to ps4. They also claim that us gamers should not worry about specs anyway... And that this is no longer about bits, even though they talked about transistors at their reveal...
And some people believe them... scary stuff.

No I didn't.
I said it'll take at least 2.5TF GPU in a pc to do what the One's GPU is capable. A sentiment that I still stand by.
I was optimistic about the One's graphical power despite the 1.24 teraflop GPU because of the move engine and Esram, and when PS4 only had 4GB of ram, confident that it would best the ps4 in ports due to a 1.5 gigabyte ram advantage.
This was back during the whole wizard jizz phase, which proelite was a champion off.

With their own number thrown in to make it work.

Cboat only ever confirmed yield problems. The rest was speculation based on what Microsoft's approach would be. A downclock seemed the obvious solution because it meant they could 'ship' more consoles. With MS suddenly announcing that power doesn't matter, I'd say it's likely they went with this option.
People shouldn't do math with things they don't fully understand.

The RAM is embedded in the GPU.
