Forums - Microsoft - Penello specifies why X1vsPS4 performance difference is overstated

everything operates at the same frequency in this gpu architecture (unlike some older nvidia cards)

Why Penello doesn't talk about TMUs (texture mapping unit) there s 48 in X1, 72 in PS4.

No words on ROPs as well? 16 vs 32 (that's a 100% increase). ROPs are very important..

PS4 Onion and Onion+ share the same bus and, hence, the same bandwidth. Onion(+), however, adds an additional 10GB/s bandwidth to the 20GB/s of the CPU bus, which is not to be confused with Onion(+), resulting in a total of 30GB/s of cache-coherent bandwidth.

There are too many here with exactly that and they are convinced in their own minds that their view of things is the correct one.  

This is absolutely hysterical.

You are the only person in here oblivious to the reality of the situation besides perhaps Machiavellian. Developers have confirmed an advantage for PS4, multiple times. 

Seriously, go do some brief googling. It isn't difficult. Your devotion to living in ignorance is proof that you simply do not want to know the truth.

Why did I expect Penelo from Final Fantasy to be here?

Kinda feel sorry for some of the hardcore Xbox guys....you guys will probably believe all this talk by Penello. When its painfully clear to any tech novice that a lot of the stuff hes saying is PR.

Sony guys will probably automatically argue with everything he says...whether right or wrong lol.

I encourage everyone to do some research and see how these things work for yourselves and then judge the comments.

Blindly believing what someone on the internet says, whether that's a GAF user or some company executive is the worst thing you can do.

Seems like Penello's intentions are good, but i feel this wont end well for him. If he doesn't strongly back up all the statements he made he will probably get banned very soon. That will be very interesting.

Don't.

I think you're misunderstanding what is going on here.

That's not how mathematic works.

 

(1 CU x 853 mhz x 64 ops x 2 cycles)  x 12  

is still the same than

12 CU x 853 Mhz x 64 ops x 2 cycles

= 1 310 208 fl ops

 

A 72% increase would be this gpu at 1376 Mhz (and probably burn quickly)

No.  A GPU is parrallel.  Therefore CU's can run independent of each other.  I can have one CU running a job each clock cycle, and another running one job over 853 clock cycles.  Because those each of those CUs will reduce the time to run an operation, the effect of those savings become accumulative.  For example, @ 800GHz I wouldn't be able to run 1000 operations.    This means it's capable of running 57 more operations. 

PS4 1 CU @ 800MHz @ 943 operations per clock cycle
XB1 1 CU @ 853MHz @ 1000 operations per clock cycle

So, at the end of one minute.

PS4 1CU @ 800MHz @ 943 operations per clock cycle = 754,400 operations per minute. 
XB1 1CU @ 853MHz @ 1000 operations per clock cycle = 853,000 operations per minute.

98,600 operations more.  Or 105 more clock cycles to do the same amount of work.  That's a 12% difference in performance right there.  Not to mention, that's one CU.

How am I misunderstanding what's going on here?

The majority of people in this thread dont know what they talking about. Some people try and make it seem as they do but they always slip up with something so crazy that it just reeks of ignorance, bias and stubborness to be right.

It just happens that jusy about every Sony guy will argue with the OP simply because Penello is an MS employee. MS fans on the other hand will naturally defend what hes saying. But there is some serious factual errors in what Penello says. And its exactly whats happening. Xbox fans are in here defending what hes saying.

Adinnieken you yourself, an Xbox fan who usually takes part in technical discussions and tries to come off as technicall minded, made a completely factually incorrect statement about the GPU performance increase. I doubt you would have made those claims had Penello not made the comments he made in the GAF thread. This is why i feel sorry for Xbox fans in here. Im sure you respect Penello's statements as a fan but some of the stuff hes said is simply not true and unfounded.

Im sure you will argue against what im saying...but to be honest any tech novice who has any sort of legit interest in these things can see the fallacies in the statement Penello has made.

This guys reeks of desperation..

Negative arguments need more support than positive ones. Flesh out your statement, or you could be deemed to merely be trolling.


Trolling?  lol  Because I don’t like a Microsoft employee?  Are you a mod for Microsoft or vgchartz?   Okay, how about I think Penello is a hypricrite who said specs don’t matter and has spent a lot of time in the past days going on about how there is no difference between the systems. For someone who says that specs don’t matter, he is acting rather desperate as of late. Is that better now?  More clear?

You have balls attacking a mod.

• 18 CU's vs. 12 CU's =/= 50% more performance. Multi-core processors have inherent inefficiency with more CU's, so it's simply incorrect to say 50% more GPU.


Sorry, you lost all credibility with this line.

CPU's and GPU's process information completely differently.

iissshhh... CU != CPU :) He is talking about "Compute Units" in the GPU... Not sure who lost credibility here


Permalite knows that.

I dont think you understood hes post.

Edit: feel free to correct me Permalite didnt mean to speak for you!

Anyways as I understand it modern day GPU's scale almost linearly with added gpu cores. Especially in tasks that favour parrallel processing. It just happens that a lot of what GPU's do gain from this.

CPU's on the other hand are not inherently like that.

I didn't attack any mod. I just don't think I need to justify why I think Penello is acting desperate. The same way any employee I have felt acted desperate in the past, like Tretton in 06, or Jaffe throughout the years. It's not trolling if I don't like a specific employee of any company and to be called out on it for trolling when it's an opinion is wrong.
