I'm just disappointed in how weak BOTH systems are. Can't even guarantee 1080p60. The 360 and PS3 were much stronger for their time than these two systems. I have both pre-ordered but I might just go with PS4 because resolution is important to me and PS4 is more likely to give me 1080p. XB1 also costs $100 more because it forces me to buy a dumb camera.

kinda ironic that the only confirmed games that are running at 1080p60fps on real hardware are on Xbox one

And yet again, 40% more power does not translate to 40% more performance, in general closer to 15% provided the same efficiency of the software. And historically not only does MS has far better experience with this, they have historically been able to get far more performance out of the hardware thanks to more efficient software as well.

I'm not really sold on that theory.  These boxes are x86 and should be pretty easy to get the max out of for single spec machines.

 

I'm not sold on Sony having this massive advantage either, but I can't dismiss that they do have one.

The PS4 also has hUMA, the One does not. It's an AMD technology (hardware-based) that allows the CPU and GPU to use the exact same resources in memory without having to copy them. While both consoles have unified memory there still can't be any direct memory sharing (both the CPU and GPU using data at the same address). With hUMA that is possible, so there is no longer any need to copy data in-memory, which may greatly improve graphics performance.

 

However, it requires some work in the engine, so there is no performance difference if developers don't code for hUMA. First games won't benefit from it. But you can count on it that Naughty Dog and other PS-exclusive studios will work on it and it'll produce some impressive results.

 

ExtremeTech had an interesting conclusion. While for launch titles the only difference will be the base hardware differences (shader amount and memory speed) it'll be the long-term developments that will make the differences more apparent. While Microsoft bets heavily on cloud technology Sony has pulled the hardware card, with faster and more advanced components. Both will need developers to code for them, both could make a big difference.

 

(Personally, I have more trust in Sony's more conventional approach. Cloud offloading for real-time rendering is still something I don't think is all that interesting and is limited to a pretty small subset of all the computations needed. More hardware power however is something that everything always benefits from.)

No huMA PS4 or XB1

Ummm what does that have to do with anything, and again, for the nth time, the Xbox one does cloud assisted computing, not rendering. The ps4 does cloud rendering.

As I said, everything being equal, OS and hardware, except one machine having 40% raw power. It would at best offer 15 to maybe 20% more performance.

Who cares? Xbox One has Mode 7 graphics, and that's all that matters when competing with PS4's Blast Processing.

This isn't news to many of us; we knew the PS4 has more powerful hardware. ;)

No, you're misreading too. AMD basically said "we shouldn't have said that and can't confirm or deny anything". Chances are the PS4 does have it as it was initially revealed, but AMD overstepped what they could say and tried to make it right again. The PS4 uses some pretty cutting-edge tech (like the GDDR5 as the only memory), has a faster/better SoC and so it's actually quite likely it does have hUMA.

Has Xbox even got a final hardware configuration?  :D

Digital Foundry: You're demoing on PC. How's Xbox One coming along?

Drew McCoy: It's great. We have dev kits, tons of them. We have as many people seeing it as possible as often as possible. There are currently no visual rendering effects that aren't on Xbox One versus PC or vice-versa. Performance is always something we're going to be working on right up until we ship. I mean, the hardware's not done yet, the software's not done - our software's not done. There's tons of optimisation to do.

 

 

But on this game - I haven't really looked at it so I don't know - have the devs said anything about the console version game being exclusively for PS4? Just looking at the Wikipedia page I've sorta assumed that it will come to Xbox at some point purely because the game is also on Windows - therefore the devs will have experience coding for a variety of systems, including higher/mid-range rigs equivalent to XB1. 

 

However if it's for PS4 and higher spec PC's only (as opposed to a financial deal with Sony) then I think that his comments have some more significance other than just a general comment on a fact that we all know.

The higher end system will usually just be developed to the lowest common denominator. Ultimately, it doesn't matter which is more powerful as developers (unless exclusive devs) will make their engines for the least capable system and port it to the more capable one.

 

Graphics don't matter, not at this point; you won't be able to tell the difference. What matters are the games, what your friends own and availability. I know the 'Console Wars' will rage on, but I assure you it's a made up war in the heads of young people with no idea what truly matters.

 

If you want the best system: ask what your friends want, get the overall consensus and buy that system. This will be the best system for you.

I really doubt this will the PS4. PC that have this will not be until late 2014.

Even the writer of the article that said AMD retracted their statement ended with this:

"I personally feel that its more likely the original statement from AMD (that the PS4 will have the edge with a hUMA design) will turn out to be the truth in the long run..."

 

Believe what you want but I'm going to go with the PS4 having hUMA. Sony and Microsoft most likely got access to tech from AMD that isn't used in PC's yet. It's much harder to put something like hUMA in a PC since you need OS and software support, which is a long process. Consoles don't have that issue since they can be designed around a SoC.

correct. the verge confirms both consoles use it

 

 


That might sound suspiciously vague, but we spoke to AMD and it's actually true. The AMD chips inside the PlayStation 4 and Xbox One take advantage of something called Heterogeneous Unified Memory Access (HUMA), Good for gaming, good for AMDwhich allows both the CPU and GPU to share the same memory pool instead of having to copy data from one before the other can use it. Diana likened it to driving to the corner store to pick up some milk, instead of driving from San Francisco to Los Angeles. It's one of AMD's proposed Heterogeneous System Architecture (HSA) techniques to make the many discrete processors in a system work in tandem to more efficiently share loads.
