Guys, look at the post dates. I no longer have the interest to deal with 'the ps5 ssd is so advanced it will even cook you dinner' crowd. We're 2 months away from real world tests - patience. ☯
Yup, fellow computer hardware engineer here agreeing with you. Obviously.You are completely wrong here. The PS5's I/O solution had industry leading bandwidth AND latency. The PC can catch up on raw bandwidth by using similar PCIe Gen 4 SSD's, but it's not going to catch up on latency without a significant re-architecting of how Windows 10 and graphics drivers work. Yes, on the PC you can use CPU based software decoding to try and compete, but you then have to go from SSD to main memory, do the CPU decode, write to main memory and then copy to graphics memory. The PS5 goes from SSD directly into graphics memory in one step. That's innovation the PC can't touch yet. The PC folks (Microsoft, Nvidia, AMD) will work to catch up with the latency numbers, but it will take a few years. As an engineer, I recognize the innovation that went into the PS5's I/O subsystem. It's real innovation, not marketing hype.
I think RedGamingTech had a video on this. He said 2 channels, but I think it was "guessing" that it'll be based on current consumer SSD like this. I don't it was anything official.Lol, what trickery? Lossless compression is usually 2:1 ratio (usually; PS5's a bit less than that, which is honestly unusual. I'm interested to know why it isn't 11 GB/s lossless compressed as I'd expect), so lossless compression up to 9 GB/s should just be assumed given the other numbers.
More interesting part here is Sony considering 4-bit MLC chips; maybe they are still using 4-bit chips or decided to go with 8-bit chips instead. 48-bit (6 byte) bus vs. 76-bit (12 byte) bus, I figure the latter would be more desirable. But also more expensive. There's other things to the Samsung one still not known though like the number of channels, the type of NAND modules (in capacity, which can influence the number of channels), whatever cache type the drive has and its amount etc.
So yeah, theoretically it might seem better than Sony's but without knowing the other stuff that can't be definitely ascertained. Dunno to say if it is even comparable considering those other factors, because most of the work comes through the flash memory controller, not the NAND modules themselves.
isnt nvme pcie3 3gb and pcie4 5gb/s ?
I have x570 pcie4 motherboard and my corsair mp510 nvme is running 3,5gb lol. Am I ps5 ?
And nothing loads faster than on normal 500mb ssd
7.877GBps with some overhead bcause of the coding. Roughly 2%PCIe 4.0 maxes put at 7 GBps.
Nothing loads faster because no games are designed (yet) to take advantage of the extra speed on PC.
If you do any work on your PC that is bandwidth sensitive however then that's a different story, you will notice the difference there.
except that the dedicated decompressor on the PS5 uses no CPU time and can do 22GB/S. You'd have to dedicate 5 of those intel cores to match it.Time to debunk the "but muh special hardware" marketing spiel people bought hook line and sinker from Sony, with the horse's own words:
That's right. All of PS5 "special sauce" is barely worth a shitty intel core. LOL
Gonna be some harsh reality checks at launch.
This is the SSD i will be using in my PS5. PS5 and PC will be using this same or similar SSD and driving the cost down, so i really don't understand why you think "Sonygaf" would be upset. Sonygaf should rejoice as Samsung has announced the first PCIE 4.0 SSD that should be compatible with PS5.Why is Sonygaf upset? The big jump for consoles is SSD standard, speed isn't as important so not a big concern if PC gets well ahead like it does every console generation.
Linus is that you?The delayed new Samsung PCIe 4.0 is coming soon.

Two of these bad boys in raid0 is going to be:
Indeed - and this has been scientifically proven.Latency, latency, latency.
This new SSD from Samsung is basically the equivalent of them making a higher top speed sports car than they made last year. Sony on the other hand, may not have as high top speed, but still has much better acceleration and handling. It's almost as if Sony's SSD and I/O is like an Ariel Atom versus Samsung's high-end sports car.
...which happens to cost an arm and a leg !!PC's have more powerful shit, we get it, why is It such a big deal?
I don't disagree with you, but what I really think is dumb is that people think they will actually notice any difference between current SSDs and the PS5 super amazing ssd. THEY ARE FUCKING HARD DRIVES PEOPLE. Yeah, in sony exclusives you might have uber fast load times, or possibly a small amount of less pop-in but those things are not going to render or compute for you.What's desperate isn't the news that Samsung is releasing a fast SSD. It's PC gamer calling it "PS5 Rivalling!"
It isn't "rivalling" anything else than slower SSDs from competitors. As a matter of fact, more and faster SSDs benefit PS5 as much as they benefit PC.
This is the same crap as the "Unreal Engine 5 runs on a laptop!" we saw a few weeks ago, and it smells like desperation.
You need to broaden your imagination a little. You PC guys are so stuck in the "faster, faster" mindset, that you seem to forget things can also be done differently. This i/o solution will bring so much more than just speed.I don't disagree with you, but what I really think is dumb is that people think they will actually notice any difference between current SSDs and the PS5 super amazing ssd.

Raw speed is a good start. But is this correct....?
PC to get new assets from ssd...
- Game requests asset ->
- i/o driver ->
- ssd read ->
- compressed data loaded into ram ->
- cpu decompress ->
- decompressed data into ram ->
- GPU driver swizzle ->
- decompressed asset loaded into gpu ram
PS5 to get new assets from ssd...
- Game requests asset ->
- ssd read ->
- decompressed asset loaded into unified ram
Isn't this the crux of where Cerny and Sweeney are coming from? Purpose built unified memory subsystem with speed and low latency vs legacy pc I/o ?
LOL no. Depending on what kind of data, lossless compression can actually achieve very little compression. 2:1 is not that common in the lossless case.
Nothing changes. Sony removed all bottlenecks between SSD and Framebuffer. The SSD is just one piece of the puzzle (cerny) Basically, even with the fastest SSD of all time, you have the problem that you cannot load any data into the frame that currently being rendered. The PS5 allows excatly that. Absolutely unique and revolutionary and thats why we will see brutaly pixelquality (ue5 demo as a first example)
