Hmm, do you have a link for that?  I was surprised when the original stuff said one per CPU per cycle.  Even the go ol' Xbox 360 does two per CPU per cycle.  And that's really going back to essentialy 2004 tech.

That would still give the Xbox One a 2 execution per CPU per cycle advantage, more or less depending on the Hz it runs.  So kind of negating the GPU differences, or tilting power in the X1’s advantage.

Sigh, I should just make popcorn and watch the fans fight it out.

Edit - I made a mistake... the Jaguar core can decode 4 intruction per each 2 clock cycle... so 2 instructions per clock cycle.

"The decoders can handle four instructions per clock cycle. Instructions that belong to different cores cannot be decoded in the same clock cycle. When both cores are active, the decoders serve each core every second clock cycle, so that the maximum decode rate is two instructions per clock cycle per core."

Oh deary me, oh my.  This would sort of imply the PS4's CPU is only 30% as powerful as the Xbox One's, which can process 4 more instructions per cycle.  That would tilt things in the other way.  There are many people that are not going to be happy at all about this.  I think we have stumbled into a hornest nest!  RUN!!



 

Really not sure I see any point of Consol over PC's since Kinect, Wii and other alternative ways to play have been abandoned. 

Top 50 'most fun' game list coming soon!

Well from what I read until now both have the exatly the same CPU.

Rumors have always maintained one per cycle which is why I've had that in OP for awhile now. Then Sony themselves confirmed it.

I'm thinking this MS guy made a mistake or wasn't referring to same thing we're talking about.

I'm waiting for more clarification on that as well as the nm sizing before I change the OP.

Yes, superchuck I was referring to your excellent thread and charts!

But ethomaz has shown, it looks like the PS4 can do two executions per CPU per cycle. (Actually 4 per 2 cycles provided the bandwidth is available.)

And Microsoft articulated again that they are pulling 6 executions per CPU per cycle.  That is a 66% advantage over the PS4.  Gosh, I makes me even more sad they didn't put a 2.5 Tflops GPU in the system.

"Some performance numbers were given for the CPU and GPU themselves but these cast more shadow than they do light. Microsoft claimed that each CPU core can perform six operations per cycle. The CPU is believed to be using AMD's Jaguar core, but typically this would only be described as able to handle four operations per cycle; two each of integer and floating point (though even here counting operations is complicated; the floating point operations could use vector instructions such as SSE2, in which case one operation would result in four actual computations, potentially giving eight per cycle for floating point alone)."

Read it here, they aren't even sure how Microsoft is accomplishing it:  http://arstechnica.com/gaming/2013/05/microsoft-talks-about-xbox-ones-internals-while-disclosing-nothing/

Well instruction is different from operations...

"ok after discussing on twitter seems standard jag is...

load , store, 2 int , 2 fp = 6 ops

So sounds like its also stock jag ... (seems some people don't count load/store hence confusion in thinking standard jag is 4 ops).."

Unclear yet but seems like a standard Jaguar core.

Just to add guys...

"jaguar stock is 2 instructions, 6 operations
2 integer
2 float
2 memory"

Maybe that's what they are saying.

I think this provides further proof Ethomaz started with earlier...

XOne uses 5GB of its ram and 6 CPU cores for gaming. Rest is all OS.

Were there any rumors about the WiiU coming with a harddrive? I remember the rumor about it having 8 GB internal storage, but no other storage-related rumors.

That link graphics claims that Wii U plays Gamecube discs, which to my knowledge it doesn',t and it certainly doesn't have ports for GC controllers regardless. It's only backwards compatible with Wii games. Nintendo has said in the past that some GC games will eventually be made available through the VC service.

1) You're qouting a post from over a year ago.

2) The question was in regards to a harddrive... a feature that hasnt' existed in the OP in well over a year.

3) Yes, however, I probably should have excluded that rumor from the start due to its addition of Gamecube information.



DevilRising on 23 May 2013

Just clarifying.lol

 

Also, from what I gather, the Wii U's custom GPU, while weaker, as far as I can tell, should still be able to keep some kind of respectable pace with the competition this gen. Especially considering Wii vs. PS3. Ultimatley, I'm not a "graphics guy", so good graphics are all I need, and art style and design always trump raw power. So I guess it'll be fine, despite how some try to make it out.
