The I/O system with the PS5's SSD is literally running a CPU that's better than the main system's CPU. |
Well. Not entirely true.
The fixed logic in the I/O optimizes that part of the SoC for those tasks specifically like compression/decompression, that doesn't mean that it would be better at other tasks... Otherwise Sony might as well just copy and paste the SSD controller 8x times rather than use an 8-core Ryzen CPU.
The Ryzen CPU is good at a wide plethora of tasks, unlike the I/O controller.
It's why we don't use a GPU with 10's of teraflops worth of performance to replace a CPU with only 100's of Gflops of performance... Because GPU's are amazing at highly parallel workloads with relatively "simple" code branches.
Where-as a CPU is really good at serialized workloads with lots of intricate branches.
And the I/O controller is good at moving large amounts of data around whilst performing predictable compression/decompression duties.
| kirby007 said: its quite simple if the SSD is so superior they would have cut the CPU out and went with with SSD only, frankly im going with what star citizen gets as results |
StarCitizen is the only real-world example we have right now of what benefits an SSD brings.
In saying that, StarCitizen doesn't really showcase much difference between an SSD with 1.5GB/s of bandwidth or an SSD with 4.5GB/s of bandwidth, for that we need to see what the next few years worth of video games bring to the example table.
| the-pi-guy said: Considering most consoles and PCs have HDDs, games can't be designed to take advantage of SSDs. There's pretty much only one game that really needs an SSD. That might change with both consoles having SSD as being a mandatory part. |
Most gaming PC's have SSD's for at-least the OS.
| padib said: I'll just make my point of view clear: the SSD is not a big deal. |
We should wait for the games before we decide that...
| Hynad said: The SSD in the PS5 is a big deal. It will complement the rest of the PS5’s specs exceptionally well. It will make the PS5 a faster console overall than the XBSX when it comes to the user experience (having to wait for anything). |
The two big tech features will be Ray Tracing and the SSD.
We don't yet know what extent the Xbox Series X or the Playstation 5 have thrown their support behind the Ray Tracing technology just yet.
The Xbox Series X has the rasterization advantage without a doubt and the Playstation 5 has the Storage advantage, they will both showcase advantages in exclusives and multiplats to varying degrees, to downplay either I think is a disservice to the engineering Microsoft, Sony and AMD have done here on both devices.
| padib said: Why did Cerny make a whole video explaining the SSD? Is it possible that, perhaps, Sony needs to do some PR to make sure people feel like the PS5 has some kind of edge when it really doesn't? |
I don't take much credit in what Cerny or Spencer says... Or any official from either company for that matter, part of their job description is to talk-up their product lines in order to accrue sales.
Outlets like Digital Foundry and Anandtech are more credible from a non-biased perspective, that doesn't mean Cerny or Spencer is incorrect, they just have a conflict of interest, so I take their opinions with a grain of salt.
| Hynad said: The SSD in the PS5 isn’t the same identical tech as the SSDs you’ve been using in your PC. |
It's also not radically different in concept either.
It still relies on the exact same NAND a PC SSD uses... Heck, even what a Phone or Tablet uses. - The work done is on the controller side of the equation and taking advantage of the parallel nature of memory transactions, for that Sony deserves praise.
| Hynad said: Ok, but has PCIe 4.0 SSDs been available forever? No. And how much do they cost for the same speed as the one found in the PS5? How was it viable to put one such drive in older console, as you said they should have, when the expected selling price of these consoles is supposed to be around 400 bucks? A quick look at the store and you have to pay around 200$ to find something comparable to what is found in the PS5. Now, if you want to play on words, the hardware developed to support the SSD is a big deal. The use of SSDs in console will greatly affect how games are designed, as it removes one heck of a bottle neck that has been present ever since they moved from cartridges to discs. |
PC can take a multitude of different approaches, it's not limited by form factor, cost or power consumption.
PCI-E 1.0 SSD's in a wide-enough RAID array can beat the PCI-E 4.0 SSD in the Playstation 5... And unlike the Playstation 5, the PC isn't limited to 825GB of storage either.
And the PC can also take it in the opposite direction, it has smaller, cheaper SSD's than the Playstation 5.
