Next-Generation NVMe SSD and I/O Technology [PC, PS5, XBSX|S]
- Thread starter Shortbread

He has a 4 cores CPU... PS5 has 6.5 cores CPU and we aren't even sure why they use the 0.5 CPU bit if I have to guess they use it probably for the sound system of the PS5. There is a part of the Tempest engine reserved by system for the 3D audio. Sony did like this because they don't want audio to take the backseat and let audio dev being bullied by graphics dev. And tempest engine need a CPU thread to send some command and manage the audio and it will probably be managed by the system.
The CPU code is bad because it is some technical debt. Insomniac choose the easy way of two locked thread one main thread and one render thread and job worker. Now they need to change all this to be able to scale better than with 4 CPU cores underutilised on PS5. They need to do what ND, GG, ID software or Bungie have done.

If this were PS5 I would say I'm certain this is about the number of processor threads reserved by the OS. The PS5 OS almost certainly uses 13 of the 16 threads that the 8 core CPU offers. On PS4 though...

My system has:
32GB/s between the PCIEX slot and CPU - (So 3.5x faster PS5's SSD)
60GB/s between the CPU and DDR4 - (So 6.6x faster than PS5's SSD)
Oops, somehow was under the impression he had a 6 core i5. Its quite impressive then what he can achieve with a modern quad core (4c/8t). Then yes, he may want to upgrade the CPU down the road. He may also alter some settings to accomodate the four cores. His quad core may also hang along fine, its sporting a much higher IPC and better architecture. These four cores may do more than a 6 core Zen2.
And you may perhaps also have a m2 nvme drive? Its not like most gamers equipped with RTX/RX6600 or better hardware, teamed to 32GB main ram are on something less then a pcie3 nvme.
16.7 milliseconds just isn't enough time, dude!The person who said PC can't stream in new data per frame is calling me wrong?
Out of sheer curiosity, I googled around a bit to find read access latency times for my very first favorite and cheap SSD that actually did Real Work(TM) on my main gaming rig -- the OCZ Vertex 3. TweakTown used AIDA64 to process random reads and writes and record I/O latency for each: https://www.tweaktown.com/reviews/5...dex.html#Benchmarks-AIDA64-Random-Access-Time
Funny story is, my later purchase of a Samsung 840 Pro is also listed in that sheet at the same time, smoking the Vertex haha. Oh well, I priorities at the time and all that... Anyway, nine years ago cheap SSDs on PCs were pulling ~200 microsecond latency over SATA3's 6Gbps signaling. If you paid about 40% more, then the Samsung 840 Pro on the same SATA interface cut that latency by more than half to 90 microseconds.
Don't get it twisted tho, PCs are still too slow and latent to stream an entire frame's worth of rasterization from storage
I know they use SMT on PS5 but I think the time sliced reserved of one logical thread on the 6th core is probably link to audio and the game itself. But basically the system used by Insomniac fully utilise the two main thread and many worker thread are underutilised waiting some synchronisation coming from the two main threads.
The person who said PC can't stream in new data per frame is calling me wrong?
Yes.
I don't think his quad core will help when the CPU need to do more stuff on PC. I think 6 cores will be a minimum for engine where the multithreading is well done.
Probably. However the 150 dollar question is still out, a modern, fast, high clocked quad intel is very capable. These each of these cores are doing more then each zen2 core. But yes, he may want or even need to offer a sixpack for a new CPU in four or so years. Who knows.

And the PS5 version has more pop-up than the PC version, can't PS5's SSD handle the streaming? /smh

I have not noticed a single downgrade in performance between my quad-core 12100f and the six core Ryzen 5 3600 it replaced.
But noticed loads of games where I get more performance.
It will obviously depend on how a game is coded, however we also know that more cores dont always mean better performance. Those four 12100f cores might actually do more than the PS5's 6 zen2 cores (available to games anyway), im almost sure thats the case. Heck i'd argue that the 12100f is the better choice over the 3700x in most cases even going forward. Direct Storage will offload the CPU a whole lot, too.
On windows 11 atleast, all cores are available to games, usually.
So yea, your i3 12100 might actually tag along the whole generation, bar some game here and there not playing well with fewer core count due to bad optimization for fewer cores, it will all come down to that. In user benchmarks that alder lake is doing very well, not just in gaming:
Its a rather large gap in architectures, Alder Lake does many things Zen2 simply doesnt, theres HW acceleration for many modern features. Which should also help out performance, theres even gaussian/neural acceleration block in thse cpu's. The thing clocks very well too

Here’s something that no one predicted: With the 12th Gen Alder Lake-S processors, Intel is finally allowing users to overclock its non-K SKUs by tweaking the BCLK frequency. In case you weren’t aware, the operating frequency of a CPU is the product of the BCLK and the multiplier (ex: 100MHz x...

Its a 130usd cpu where i live, killer value.

I do have an NVME yes but only an average 3.5GB/s one.
Nonsense.

The PS5 version does have very obvious thank you very much.
Fast enough for practically anything coming your way this generation. Theres also gpu decompression.
If I had to assume, it would be they did not want to change anything from how the PS4 and 4Pro system OS is setup, so they kept the same CPU reservations.
At the end the Jaguar CPU was only using 6.75 cores only 25% of the 6th core before it was like PS5.
This is 100% sure they reserved some capacity of the Tempest Engine for the 3D audio into the system. This is a direct quote of Mark Cerny and this is a modified CU with DMA system like the CELL SPU and it needs to receive command from the CPU. It can't work without CPU, one of the thread is working with the Tempest Engine for make 3D audio work correctly. Mark Cerny said it wanted the functionality to be standard on PS5 and the best was to integrate it inside the system. I don't think they will let the dev do the job for them and he said audio quality was too low before and fighting for resources with graphics and graphics was always considered much more important than audio.Similar threads
