Forums - Microsoft Discussion - The Xbox One's Insides Have Changed A Little Bit Since E3 - GPU clockspeed upped

since the PS4 and X1 were pretty even before according to john Carmack, I guess this means the X1 is the most powerful now?

How I can explain lol

800Mhz to 853Mhz added 80 GLOFPS to Xbone GPU.

PS4 GPU more 520 GFLOPS than Xbone GPU.

Did Microsoft even confirm GPU info for Xbox One? I don't remeber Microsoft ever talking the insides

They didn't confirm the GPU or anything but can confirm the GPU clockspeed increase. Sounds so ass backwards

No games are out for neither consoles are can you know which one will have the most giga flops



Bet reminder: I bet with Tboned51 that Splatoon won't reach the 1 million shipped mark by the end of 2015. I win if he loses and I lose if I lost.

RRoD had to do with under engineering and poor QC. This is not an issue I'd expect to see with the XB1 in light of the fiasco MS had to deal with in the XB360.

If I actually wanted an XB1 on release day, I would be buying with confidence.

As for the upclock on the GPU; yes, it will require more power and will generate more heat, but I'm pretty sure it will be well within the design operating specs.

Keep in mind the XB1 box and its cooling system were designed to avoid RRoD type failures. The box itself is larger and I'm sure a great deal of thought went into keeping airflow and heat management at reliable levels.

On a related note, the 53MHz speed bump does not make sense at all UNLESS the system clock is now 853MHz. This means that the bus runs at that clock AND the Jaguar cores run at 1.706GHz, still eactly twice the bus frequency (any odd muliplier would simply introduce bus contentions).

And the Jaguar clock have no relation to GPU clock in AMD APUs... eSRAM is synced with GPU... there is no multiplier bettwen CPU and GPU...

Now ask yourself the question: what happens where the two "odd" frequencies meet on the APU? That sounds like a simple question. Engineering wise, it is not quite a simple one..

Tell that for all APU released by AMD until now because the clock are not synced... I even tried to found a relation but each one have it own clock... there are the same APU with the same CPU clock and three or four GPU clock (and I can't found multiplers that makes sense for all these clocks).

I don't know why but AMD APU didn't have clock synced for CPU and GPU.

I'm not saying MS can't upclock the CPU too... I'm just saying that the GPU upclock doesn't mean CPU upclock.



Considering that they never directly mentioned the initial clock speed... I'm underwhelmed and at this point we have no way to know what this actually means.

800MHz from my thread and anything talking about this was based on 3rd parties and leaks.

So this could mean that its now 853MHz or it could mean that its just getting up to about 800MHz as it was actually lower than that earlier.

The exact transcript from the podcast...

Marc Whitten

"This is the time where we've gone from the theory of how the hardware works - what do we think the yield is going to look like, what is the thermal envelope, how do things come together - to really having them in our hands. That's the time where you start tweaking the knobs. Either your theory was right dead on, or you were a little too conservative, or you were a little too aggressive. It's actually been really good news for us, and an example of that is we've tweaked up the clock speed on our GPU from 800MHz to 853MHz."

The previous clock was 800Mhz.



What is the PS4's clock speed?

GPU is 800Mhz.
