| Intrinsic said: Yes thats because on the PS4 the I/O bus is basically a SATA 2 lane. That means that anything you conect to that bus will be sharing that 600MB/s max limit. Ideally, that bus should have been a PCIE bus which would have meant that all connected devices have a pool of 4GB/s (depending on what kinda PCIE lane is used) to share from. But those PCIE lanes makes the MB cost more to make. |
Sata 2 is limited to 300MB/s. Not 600MB/s.
The Playstation 4 Pro is using Sata 3.
| Bofferbrauer2 said: Nope, AMD specifically stated that Pinnacle Ridge is NOT Ryzen 2. It will probably have a respin and "12nm process" (which is just an improved 14nm process, really) and certainly have errata fixes and a clock rate increase. However, I doubt there will be much, if any, change in the power consumption (might be a bit due to the bugfixing and metal spin and the improved process, but don't expect anything more than a couple % out of that) and apart from bugfixing it's still fundamentally a first gen Ryzen, hence why AMD doesn't call it Ryzen 2. At best, it's a minimal shrink from the original Ryzen without any other real improvements. It's a Zen Refresh, but no Zen+ or Zen 2 |
I am calling it Zen+ as it's just a refresh, not an Overhaul. Zen 2 is after that.
With that however...

Zen 2 will be in production 2nd half of 2018 and if my prior predictions have been accurate will drop in 1st quarter of 2019.
You are correct on the 12nm process being a rebadged (Albeit improved) 14nm process, which in turn is based on 20nm but with Finfet.
Global Foundries pegs the improvement at 15% in regards to density, 10% improved performance, which coinciding with a respin could net some gains.

Of course when it comes to power consumption, AMD is likely to gobble that extra TDP headroom to push for higher clocks, will we finally see Ryzen break the 4Ghz barrier reliably?
| shikamaru317 said: I agree. I simply can't see Sony waiting later than 2020 to release PS5 personally. We are already starting to reach that same point last gen where 360/PS3 started to feel like they were really holding gaming back. The sign that that point has been reached is that framerate issues start to become commonplace on consoles. By 2010 framerates issues were becoming increasingly common on 360/PS3, and by 2012 we had games like Far Cry 3 with frame drops into the teens during some scenes. Meanwhile this gen we have been struggling with framerate issues from the start of the gen thanks to the weak Jaguar CPU's, but now we're even starting to see some GPU related framerate issues, and it's only going to get worse as PC continues to pull further ahead. I think 2021 is the absolute limit that this gen can reach, and more than likely it will be 2020 for Sony. MS may be able to hold off until 2021 by remarketing the XB1 X as an entry level gen 9 console, able to play the same multiplats as PS5 at a lower 1080p resolution, but the Jaguar CPU in X, even though it is heavily overclocked, may prove too weak to even play gen 9 games at 1080p 30 fps. |
Allot of what you describe (Framerate issues, resolution issues) and so on is partly why the Playstation 4 Pro and Xbox One X exists.
Next gen will probably take awhile to get kickstarted though, the technology doesn't really exist yet for a generational increase... Otherwise the PS5 will just be an Xbox One X in a different box... And who wants that?
Longer this generation is pushed out the better IMHO. We have never had mid-gen refreshes before... And I want next gen to be a big jump.
| Bajablo said: SSHD's f*cking suck though.. but i guess if you can code it to work with the game you are playing and streaming all files into the SSD part of it.. but.. then you could just have an SSD straight up.. |
However... They make a stupidly big difference if you are dealing with terrible 5400rpm (or lord forbid) less mechanical disks.
I mean, it's still not going to turn it into a speed demon, but it makes the slow less slow and more tolerable I guess.
I have a 32GB Sandisk Readycache drive in an AMD rig here... It's not a replacement for an SSD... And that's 32GB of the stuff.
| shikamaru317 said: But, drives will also need to be faster than they were this gen, loading the 4K textures and higher polygon character models we'll see next gen will make load times even longer than they are this gen, so a standard hard drive, even if it's 7200 RPM as opposed to the 5400 RPM drives we have this gen, simply won't cut the mustard. |
SSHD's are essentially your regular 7200rpm or 5400rpm drives with some flash memory sprinkled on top.
You don't actually need an SSHD to get SSHD like performance.
| shikamaru317 said: Yeah, PS4 and XB1 only have a SATA 2 bus on their mobo's so even if you do put an SSD in them the SSD will be severely gimped. Plus like you said, the games on consoles just aren't coded to work with faster hard drives like SSD's. |
Which was fine at the time... As Sata 2 tops out at 300MB/s and the 5400rpm mechanical drives they used topped out at 80MB/s sustained, remember these consoles did release in 2013 and we are about to enter into 2018.
| shikamaru317 said: Sadly, though the PS4 Pro has a SATA 3 port, it still has the slow bus on the mobo, so there is very little difference. |
There could have been something else at play.
You could throw 100GB/s of bandwidth at an SSD, but if it only tops out at 200MB/s, then that's all you get.
But if I had to choose between an SSD that does 150MB/s and a Mechanical disk that does 220MB/s... It will be an SSD every single time. Every time.
I was an early adopter of SSD's and opted for the OCZ Vertex back in the day, my mechanical disk RAID array was pushing 450MB/s. The OCZ drive was pushing about 250MB/s. Guess which provided the better experience? The SSD.
It made everything snappy because of the stupidly low access times.

Not a real limitation as the majority of Mechanical Disks, heck even probabably SSHD's are not going to be pushing past that 600MB/s barrier.
Heck there are even a heap of budget SSD's (That a console is more likely to use) that wouldn't either.
The other issue is of course... External Hard Drives. This generation has almost necessitated their use (I have two 4 Terabyte drives dangling off the Xbox), next gen will only exacerbate the problem.
An Internal SSD is NOT going to assist in that regard.
But... If Microsoft/Sony were to include some NAND on the motherboard to cache *all* drives (Optical, Internal and External) then that is a better approach overall, don't you think?
