Technical Comparison Sony PS4 and Microsoft Xbox

[eastmen]

Didn't MS (and/or Sony) announced that the next gen console games will have to be forward compatible. And by that I assume, it will have take advantage of faster processor, memory and gpu. From a technical point of view, it's doable...look at all the games on the PC.

However, from a customers relationship point of view, it's kinda nightmarish. Imagine, buying a first generation console and not being able to play a game as good as the later generation. Imagine the advantages, players with new consoles vs players with older consoles....eh...oh...I see...they want us to continuously buying newer console....

Why ? in stead of buying a shrunk xbox one in 2017 like you did with the xbox 360 s in 2000 you simple by the xbox two.

I mean think about it , the xbox slim came out at $300 5 years after the xbox 360. in 4-5 years instead of doing a full transition to a new generation they can just release a faster console that will play current games in higher resolutions and frame rates and then play the newer games.

I'd rather that than buy the same hardware in a better looking form multiple times in a 7 year block

While I agree with you...but i can understand what they're trying to do.

It's sort like Intel's tick - tock cycle. In one cycle, they release generational improvement...in the alternating cycle release a faster version. By alternating this, they can get faster cycle without the high cost of developing new generational console.

Now, how hard are they going to push the speed thing? I'm not sure, because it's easier said than done. However, my point is that they have talked about games needing to be forward compatible...And they design have abstracted a lot from the developers, so at the end of the day...those big budget games can really benefit from this...as the development cycle is long and they need to recoup from it even if it's in between generational hardware releases.

If its amd again they could simply take whatever 2017's jaguar is and stick it with a gpu and most likely ddr 4 and call it a day. You'd get a lot more performance . By 2017 I could see 4k tvs picking up a lot of steam and so maybe they will target that.

I don't think they really need to do another true console cycle again. Just put out a new faster fully BC box every x amount of years.

Like a slower ipad cycle.

And I guess more importantly, if they see DD is doing well, they might do what Sony did with PSP --> Vita. As currently, the framework for medialess gaming is set...it's just matter of time, before they pull the plug on the optical disk. They will probably do a speed bump, to offset the lack of OD...Then they have full control of the system - games (and it's distribution), media (digital) and your life (because the Kinect will have private pictures of you) .

I'm pretty sure no manufacturer has moved to a completely different memory architecture mid-cycle. I'd expect every variant of the machine to have DDR3 for the simple reason that any game released needs to work on every XB1. It simply won't do for some machines to have half the bandwidth of others.

They wouldn't get half the bandwidth. They would halve the interface width, from 256bits to 128bits, and double the transfer rate, from 2133 to 4266MT/s. Bandwidth would be the same.

Each 64bit DDR3 memory controller would transform into a 32bit DDR4 controller. Command rate could be kept the same with double length bursts (or two consecutive requests to simulate 16x bursts).

They won't do this until power consumption is lower and cost is lower, - or they have to because the APU is shrunk and becomes pad limited (but at 400mm² that will take a while).

Cheers

Has anyone done anything like that in console history?

Carmack being impartial.
Wow I totally EXPECTED this.

Yeah , so what ?

I can see the theory behind it for example he doesnt say xbox is weaker but that isnt the question he was asked or the one he answered.

It may as well read 'I dont want to burn my bridges so I won't commit'

You know,Carmack is a rocket science man...
In the past he didnt doubt in bashing the Cell...

Carmack haven't had any problems deriding past consoles. If one of the next gen machines was clearly inferior, he would let us know I think.

There's not a lot to talk about ... i mean comparing the tech side of these machines .
It's just as clear as black & white .

If there are exclusives on the way maybe not.Bethesda may advise its employees not to give winners.

 

[DJ12]

Past sony consoles dont remember him saying anything particularly bad about xbox as it was the easier console to work on and get wins with due to the gpu.

I imagine most of his ps3 work was trying to get it running as well as the 360.

Still hes not answering that question he was asked which he would recommend not which one has more power or will make better games.

maybe the esram? less likely, ms did that upclock after all?

dev tools? xbone actually using less os resources?

maybe a general idea "both machines are good, same base architecture, I dont care about a few less shaders, so i will decide on other things haven't made up my mind yet"?

Kind of funny to see so many attacking his integrity cause they dont like what he said. Which he didn't say much anyway.

the easiest path out of that would have been not to address the question at all, considering he likely picks one out of a hundred twitter q's to respond to. there was no need for carmack to address it if he was under some mythical gag order.

be happy he said ps4 was well engineered.

 

[DJ12]

A few less shaders is a stretch and mentioning a potential upclock every other post when its been explained to you why its not happening is starting to get more than a little old.

In what world is a few 33%?.

Even if all those happened , it's still an ocean of difference .

I wouldn't call it a "few less shaders" ....
Carmack just being polite and diplomat , the machines are not out anyway .
