Lol I haven't seen that gif in forever.
I own an Xbox One and a PS4 and the biggest difference I've noticed between the two machines outside of the games is that one is uber-fast and responsive and the other is clunky and sluggish. Can you guess which is which?
The PS4 is the console that has a slick and speedy interface with the various options, including the Store, all opening instantly. The Xbox One, however, loads all its apps on demand so going from the Home screen, which feels much more chuggy to navigate on the PS4 as well, to an app such as the Store or Internet Explorer requires a 3-5 second wait while it loads (unless it has been loaded previously then it is pretty much instant). I much prefer the PS4's interface for this reason; that and the fact that it is laid out in a logical manner and doesn't require voice-commands to make it usuable!
Anyway, I think the PS4's interface feels quicker because more of its features are held in RAM at once which would explain the 3 GB allocation. Even if I turn my PS4 off rather than into standby mode then on, it boots up far quicker than the Xbox One from the same status.
The PS3 also used a big chunk of the system's 256 MB of system memory (it also had 256 MB of RAM for graphics as well) for the operating system but Sony reduced the footprint over time. I expect the same thing will happen with the PS4. In fact, it has to because at some point the PS4 is going to support new features such as CD playback and custom backgrounds which would require freeing more memory for those.
I was thinking the same thing. The presentation wasn't about 5gigs of RAM. Why is everybody going crazy over it, that amount is plenty for games. We are coming from only having 512MB.
I think people are making a big deal for nothing.
The thread title shouldn't have been changed either.
I agree, presentation was not about ram as that amount will change over time but changing the topic to reflect that one element is borderline click bait.
Only 5GB of ram for the games? Well I'm now going to revise my review scores down 2 points per game, because they are now inferior.

I do love how pressing the home button on the PS4 is so quick. I still use my PS3 regularly, so the difference really stands out. I like how I can stop watching something on Netflix, exit, check out the store, slip in a quick game, and then go back to exactly where I left off on Netflix.
That being said, developers should have the option to force the user to close Netflix (like it does if another game is running) if they want to use that extra memory.
no FF quality yet
So what is the additional 256MB of ram from Samsung used for then?
Oh ok.Standby activity? I guess.

GDDR has really high latency. People need to remember this when they praise GDDR in the PS4. 200+ cycles to access main RAM is a lot. It's very important for them to use the caches well.
This nonsense again?

Nilla's Friend said:: I finally understood something though
: Sony is doing so well in part because they overspeced the console to do GPGPU computing.
: So, Sony is telling devs they expect them to use the GPU for general calculation tasks
: MS is partly providing dedicated Co-Processors for many of those tasks, and also providing cloud processing for high bandwidth latency insensitive tasks
: but as of today, most games aren't doing GPGPU processing, so they have an oversized GPU to use, which means they can hit performance numbers without optimizating
: On XBO they probably don't know how to use all the co-processors yet, so they aren't using them, but since it wasn't designed for GPGPU, there isn't a lot of leftover overhead
: couple that with the fact the games aren't optimized yet, and that explains a good chunk of what seems off to me.
: If they ever start using those co-processors, and/or doing heavy latency insensitive processing up in the cloud, and want to have those same features on PS, they would need to heavily cut into the GPU overhead
Interesting, so the Xbox One must use the system ram for these things then?Background related stuff (in combination with the 2nd processor). Copying the bluray content to the HDD (installing), downloading stuff, streaming, standby tasks (downloading etc.).
I sent this article to a friend of mine who is a real tech junkie, been in the industry for years.
We game together, but he is highly indifferent to the "Console Wars"
this was his opinion on the info here, (I understand some of these words) and one of his low level understandings on the performance gap as of today
right.
.. right?
either way, good on Sony, put together a great box

Your friend is regurgitating xb1 fan talking points, he doesn't sound indifferent to me.
The current PS4 UI isn't using 3GB of RAM. There's no way. So what's using it?

It's in the OP, 200+ cycles to read from the main ram pool to the CPU. A perfect read from DDR3 is about 30.The 190 cycles refer to cross-module access to the L2 cache, not main RAM. In addition, the latency is dependent on the memory controller setup in GPUs and not inherent to GDDR5.

I'm not following you. It is an order of magnitude as demonstrated by the OP. From the CPU to main ram is 200+ cycles; from L2 to CPU is 20+Main memory access is an order of magnitude slower than L2. Source: Intel
Under no circumstance is the difference between L2 and main memory only 10 cycles. Don't be absurd.
Why do you think that? The difference is pretty close to be as predicted by comparing framerates from similarly specced PC configurations.I dont believe there is anyone that believes launch titles are ever a good benchmark of technology, but there is clearly a larger difference than there should be.
What's was your point with implying the much lower DDR3 cycle count when replying to someone that is talking about the latency having to do with the controller and not GDDR5.I'm not following you.

not really. Sony has a 'little extra' for GPGPU, but they also have plenty of dedicated silicon for other things just like Xbox one
- video compression/decompression - for remote play/twitch streaming
- ARM + dedicated RAM - for background downloads etc
- dedicated hardware for audio, seems to be similar to what is in the latest AMD cards
I missed that slide you where referring to. Nevertheless, GDDR5 clocks higher than DDR3, though, so "cycle" != "cycle" when being used as a measure of time.
I hope not.I really hope their comments on 1080p/60 is a hint that they intend to pursue that route with their PS4 projects. Their games already looked so amazing on PS3, that I think even targeting the higher framerate they're going to deliver some incredible results.
Interesting read and presentation, I can't wait to see what ND will do with the PS4. To bad we didn't find out at what seeped the the CPU is clocked.
What is the function of the additional ARM processor? Two cores and 3GB of ram seem like a lot for the what the PS4 OS is doing now.
