| Trumpstyle said: A 4 core cpu would just not be good enough for next-gen system especially with 1 core being taken by the OS. If you wondering why exactly 7 cores instead of 8 cores it's cause it will be cheaper to produce with 1 core disabled. |
Quad core CPU's have taken the role of the old dual-cores in terms of performance.
I.E. AMD's Ryzen's low-end are Quad-Cores.
Intels i3 is now Quad-Cores.
So it goes without saying... Regardless of the amount of cores that is chosen (8-Jaguar cores were roughly comparable to an Intel i3 Dual Core), having CPU performance around that level is probably something we might expect.
| globalisateur said: SMT (2 threads by core) is not ideal for a console, apparently it's kind of random. I think it would make much more sense (and be less expensive anyways) for 8 cores, 8 threads. Also BC with PS4 would be much easier like this. |
The Xbox 360 had SMT, but it did bring with it some caveats that I won't get into here.
In short though, SMT would not prevent backwards compatibility, but when leveraged right can allow you to extract more performance out of each core.
| globalisateur said: AMD produce their CPU by chunk of 4. So it would be 6 cores (with 2 disabled) or 8. |
Not even a factor when we start talking about monolithic semi-custom SoC's.
| Intrinsic said: STORAGE: I believe the PS5 (and next Xbox) will finally jump to solid state drives. And of the M.2 variety. While the consoles will support PCIEx4 based nvMe drives by default (~2000Mb/s + reads) the consoles will come with a 1TB sata 3 based m.2 drive instead (~500Mb/s reads). Right now you can get a 512GB M.2 sata ssd for under $150. |
They will go with whatever is cheapest. - Even the Xbox One X isn't using the biggest, fastest mechanical disks and that was a "premium" console.
SSD's/m.2 drives still command a premium and will do so even in a few years from now.
Plus the demand for NAND is increasing, so costs could actually increase, especially if NAND fabs retool to start taking advantage of higher DRAM prices.
| withdreday said: They almost have to with the PS4 Pro being so under powered compared to the Xbox One X. The One X is even out selling the Pro now, so most current owners don't even see the upgrade as being worth it. I tend to believe most of the rumors that the PS4 Pro will become the baseline PS4 and drop $299 the PS5 will be the "premium" console. |
The Xbox One X outselling the Pro is an inconsequential issue as the Pro isn't the bulk of Playstation sales anyway.
| withdreday said: As far as Ram, Maybe 16 Gigs of DDR5? Remember this thing has to be able to be priced at Sony's ideal price point of $399. I can't imagine that they want another PS3... |
DDR5 isn't going to happen. JEDEC has only just finished demonstrating the DRAM and hasn't even finished ratifying the standard... And is thus probably still a few years away from a market release.
It does promise to double the bandwidth and density of DDR4, which means it's not going to be enough for next gen anyway unless you implement a stupidly wide bus.
It will be GDDR6, it will be what will offer the greatest benefits, higher capacities and good enough bandwidth/latency.
GDDR6 is currently ramping up production right now, so costs will be leveled out by the time 2020 hits.
