More like a 2060 Super.

Every platform has content that another platform won't get, so your argument doesn't take you very far.

Only as powerful as a 2060 Super you say? Do you care if I make a thread based on that, pointing out that you said that? That's worth it's own thread, and you'll either be laughed at or praised in 9 months.

By your logic, Atari Jaguar was just as good as SNES. Not all content is the same, and one fantastic game is worth thousands of awful games.

Wait...he actually said the XSX is only like 2060 performance? I didn't even read that. It was benchmarked against a 2080 paired with a 16core CPU and 64GB of ram and had equivalent performance while running a two-week-old unoptimized code.

Both the PS5 and XSX are in 2080 GPU territory and that's before specific optimizations are kicked in. Simple as that. 

Like I don't get our PC friends at times.

Yes. Sony's claim(and only) throughput is 5.5GB/s of raw data. MS's own is 2.4GB/s. That 7GB/s number is sony's compressed "equivalent" throughput. So basically 5.5GB/s of real-world data would still be sent but after decompression its equivalent to 7GB/s. And no one is saying that can't be done in PCs a well.

The reason sony needs PC SSDs that has a bandwidth higher than 5.5GB/s (truth is sony didn't even say they needed a drive higher than 5.5GB/s and this is coming from DF), has something to do with 6 priority something on PS5 vs 2 on PC SSDs and PS5 APU has to arbitrate the other 4 or something like that.

I'm not nor have I ever been about what can be done on PC and can't, but to be fair, at the time when Cerny actually said what he said back last year (and he even alluded to this exact observation himself during talk yesterday) there wasn't a PC SSD out there that was as fast as the PS5 SSD.

And to be fair I would think you should know better than bring up RAID... that's like comparing apples to oranges. Cause I doubt when anyone talks about having a single off the shelf SSD solution to put in their console or PC they are talking about a RAID setup.

Not really, compressed PS5 can get 9Gb/s worth of data (peak of 20 depending on the case).

The 7Gb/s was Cerny explaining that due to the difference in design between Sony solution and the standard PCI 4.0 design a 7.0Gb/s would likely be needed to reach the 5.5Gb/s on PS5 due to the overhead of the controler on PS5 having to match the lack of the 6 levels of priority.

Yes and no... technically we are kinda saying the same thing.

The PS5 SSD has a physical throughput of 5.5GB/s (lets call it a gate). However, based on the Kracken compressor thingy and thanks to its specific decompression chip, it can send up to 20GB/s+ equivalent worth of data (depending on how well compressed that data is) through that 5.5GB/s gate. And this is not something that can be done in PCs because they don't have specific hardware for data decompression and even more so designed for a very specific type of decompression codec.

the 8-9GB/s Cerny used in is examples just to illustrate this pint and assuming current industry-standard LZ (something) compression is used and not the Kraken compression which is significantly better and which their specific silicon for compression is better suited to handle.

Everything else abt the off the help SDs though is accurate and I fully agree with.
