While both consoles make use of an eight-core AMD Jaguar processor, the PS4 features 1,152 GPU cores compared to the XB1’s 768 graphics cores. Sony’s new console drives 1.84 TFLOPS as a result, compared to the XB1's peak shader throughput of 1.23 TFLOPS.

The PS4 also has the edge when it comes to system memory, featuring 8GB of 5500MHz GDDR5 memory compared to the XB1’s 8GB of 2133MHz DDR3 RAM. The PS4 has a rumoured 512MB-1GB reserved for it's OS, while we know the XB1 has 3GB reserved for it's 3 OS'.

Embedded memory and embedded memory bandwidth for the PlayStation 4 are still unknown factors.

But what else do we know? Aside from specs, a lot of "features" have been revealed, so let's recap those.

- LIVE will continue to exist as it did this gen, with all online multiplayer and entertainment features behind a paywall (pricing not yet announced)
- Games can be suspended and resumed, even after turning off console
- System has constant access to the "Cloud", which could be theoretically used to offload AI routines and the like to take load off of the CPU

As far as I know, that's everything we know up to now. Did I miss anything? If I made any errors, let me know and I'll edit. I haven't been following it as closely as many here, so there may be updated info I wasn't aware of.

All these numbers and we have hardly seen any games. Both Sony and MS really need to pull their fingers out for E3.

Yeah I actually expected more spec comparisons during the week.

I think the ps3/360 spec war kind of killed of spec comparisons. It really all comes down to whose making what and which is the lead platform.

PS4 is including a headset in every box.

Have they confirmed they won't put a headset in the box?
Use your Kinect. It's odd how it feels like PS4 is going to be the early 360 successor while Xbone feels to be the early PS3 successor.

I think the PS4 comes with a headset included in the box. The headset connects to the controller.

EDIT: beaten.

Linkypoos?

might be worth citing sources for each factoid in the OP, so you don't get loads of questions like that.

This is significant in a couple of ways. One, we’ve received confirmation from Microsoft that the company will not be packing in a Communicator headset in with the Xbox One, as it did with the Xbox 360 (this is presumably because the unit comes with a next-generation Kinect sensor bar in the box).

Let's be fair here regarding backwards compatibility. The PS4 has no bc at launch and supposedly will become it later on (if at all, as of now it's just PR talk).

Microsoft never said all Xbox One games will have dedicated servers. They simply said that is an idea for the 300,000 servers.

Is the difference between DDR3 and DDR5 really that big? So would like 4GB of DDR5 be equal to 8GB of DD3?

From what I understand GDDR5 is the graphics optimised version of DDR3.
GDDR5 has more bandwidth, but DDR3 has lower latency.

But as we buying games machines, it's likely that the GDDR5 is more beneficial for games with funky graphics.

OP is Misleading the actual answer to what we know so far is NOTHING! Sony has not said anything about their policy or on online or used games Only a controller! Ms has not address the same thing only a console and trailers. until we see the games at e3 running on hardware and people playing them and we get answers Im not putting stock in any of them. The idea that ms wont have games and sony wont have media stuff is just fantasy.

This tech stuff is generally over my head but the consensus prior to the PS Meeting was that Sony would have an advantage with 4GB GDDR5 over Xbone's 8 GB DDR3.

the cloud thing, my bro in law was over here, trying his best to say the xbone was all that, and he brought up the power of the cloud, in all seriousness, he said that, I love the man like my brother, but I couldn't help but laugh my ass off....
I have no doubt this unlimited cloud power stuff will make for an effective marketing tool. I've already seen it on other forums.

I don't believe I mentioned online or used games in the PS4 section? I specifically attempted to avoid anything that wasn't already confirmed.

I believe this was confirmed via Guerrilla's powerpoint presentation, was it not?
The info they gave was that their demo ran on a total of ~4.5 gb of ram on the game side (3 gigs for GPU ops and 1.5 gigs for CPU ops), and no info on OS footprint.
