What I think is interesting to note is that the PS3 had only 20% of the memory bandwidth that the Xbox 360 had, yet it was still able to offer similar levels of game quality to the Xbox 360. Yet there are people who want to doom and gloom about the supposed significant difference of the Xbox One's bandwidth to the PS4's. With the Xbox One and PS4 we're talking about an even smaller relative percentage difference in bandwidth.

Is that adding things up again?

Xbox 360 512Mb GDDR3 bandwidth is 22.4Gb/s
Xbox 360 10Mb EDRAM is 256Gb/s

PS3 256Mb XDR main RAM 25.6Gb/s (3.2Ghz)
PS3 256Mb GDDR3 vRAM 22.4Gb/s (700Mhz)

vs

XBox One 8Gb DDR3 68 Gb/s
XBox One 32 ESRAM 102 Gb/s

PS4 8Gb GDDR5 176 Gb/s

The unified memory pool together with the blazing fast EDRAM buffer did give 360 an advantage in framerate stability.
This time the xbox one's 'fast' ram is slower then it was on 360 and the entire ps4's memory pool is faster then both. Plus the Xbox 1 still has to make an extra step to fill the 'fast' memory.

We could do something as equally rediculous as adding bandwidth up together, let's look at a weighted average by memory size
360 : ps3 = 26.8 : 24
xb1 : ps4 = 68.1 : 176

We're talking about a much larger relative percentage this time.

Did you just add the bandwidth together for each consoles RAM? Considering your earlier posts, surely you know better than this?

The memory bandwidth is fairly similar in the PS3 & 360 (around 22-24Gb/s). The 10mb eDRAM does have a high bandwidth of 256Gb/s, but was only useful for a small subset of tasks so is not all that useful for comparison. Then there's the different memory architecture which makes direct comparisons problematic.

Any advantage is theoretical until we see it affect a game. I just don't see the benefit of the sheer volume of discussion about this.

Seriously, a more meaningful discussion is Forza Motorsport 5's graphics in comparison to Driveclub's graphics. Of course I'm sure bias disguised as personal preference would even affect those discussions.

This is really going to be an annoying gen for the forums ...

360's EDRAM was connected to the GPU by a 32gb/s bus, so while it operated internally at 256gb/s, that wasn't the "full" bandwidth it actually had.

True, I forgot about that little bit of info.

Forza wins. DriveClub is doing way more real time stuff that technically is better, but who cares what the numbers say. It was smart for Forza to bake and fake a lot of things. Looks amazing!

Until you see the sun setting in DriveClub while you drive(Atleast I hope they have that).

Unless each RAM have a dedicated bus and the APU can access them and load and use their data simultaneously, their speeds shouldn't be added together, but the actual overall speed will be their weighted average, using as weights their respective use percentages, so the theoretical maximum speed will be in ideal conditions the highest of the two speeds, not their sum.

If I have anything wrong, someone let me know, as long as it is confirmed, and I will adjust it. Truth is, these consoles aren't that far apart in capabilities, overall, but the PS4 will have some graphical advantages in the end.

Very nice table.

The Xbox One Wireless Controller does not use Wi-Fi Direct.  It uses a proprietary RF-based wireless technology. (Confirmed by Microsoft's Marc Whitten and Larry Hyrb).  Most likely, this is a UHF-based wireless technology based on a relatively recent patent awarded to Microsoft.

The OS names are technically Orbis (PS4) and HyperV (Xbox One).

Xbox One's network connectivity is the same as the PS4's as listed except it also includes Wi-Fi Direct.

The Xbox One can do the following too:

- Xbox One will update while switched "off"

- Xbox One will play digital titles as they download from the Xbox LIVE.

- Xbox One will immediately pick-up any game from where you left off.

- The Xbox LIVE friend limit Is Increasing

- Xbox One charges your controller while sleeping.

- Xbox One can share recorded gameplay on social and video sites using the Upload center.

- With Xbox One you can invite an online friend play your game in real time.

Also, RAM is R A M, not Ram.  It's an acronym for Random Access Memory.  The Xbox One also has 32MB of ESRAM.


The PS4 OS isn't Orbis, it's like Dynamic or something.

Xbox fans don't have to be jealous, Forza Horizon is already doing it.
