Upcoming ARM v9 product with 45 TOPS NPU

I’ve been wondering the same, suspecting that there might be chip variants.

Yes, CD8180 is for SBC, yes, we have a dedicated code name for the chip, more flexible on the voltage/frequency, CP8180 is for PC, consume level, more stable, at least this is what they said from CIX.

RK3588 implements PCIe Gen3 x4 (or 2 x x2 or 4 x x1) and three times Gen2 x1.

Yes, but as far as I could see there is no board that has all of them available for user.
What uses those in Rock5B? USB

P1/CP8180 has 16 Gen4 lanes.

Same thing, I’m thinking about those available to use vs things that there are already available on board (no 10G)
For NAS build something is needed to connect hard drives and networking, this is all that we have.
PCIE 4.0 2x should be ok for 10G NIC (even for two 10G), but we will need to wait some time for cards that uses pcie 4.0

But ofc it’s great to have all those extra Gen4 lanes… even for the NAS use case since additional NICs might be attached to the E-key M.2 slot and then the requirement for storage bandwidth automagically increases as well.

Here some RK3588 experiments with multiple 10GbE NICs carried out by @willy back then: ROCK 5B Debug Party Invitation

Thanks for reminding me about this. @willy very nice setup! I’m trying with PEX8725 + 2x AQC113 + 2x nvme (or sata card in future). This should be perfect for NAS with both network and storage wired via full pcie 3.0 4x.

No need to speculate about performance there’s an early geekbench result for the Cix P1: https://browser.geekbench.com/v6/cpu/8545345 (please keep in mind that it’s most likely been done on beta software)

Both (exynos and cix) are close, both significantly faster than A76 on RK3588.
Of course as we all know - those two are early tests, not optimised yet and GB has its own problems. With mature SOC like RK3588 there are many results to check out, here we have only those and probably they are not optimised yet.

@dominik Yes, if You plan to setup a powerful workgroup/company NAS,10 Gpbs ethernet is probably nice. Willy and You have a better idea than me for sure, but this also increases the costs if You don’t need it. My home network relies on CAT6 (partially CAT 6A) but with 1 Gbit power efficient switches for the moment…

10G stuff is really cheap today. Cat6 can work with those on shorter distances (2.5G is ok for sure),
Wifi7 routers without 6GHz band can go beyond 5G, with 6GHz they may reach more than 10G, and this stuff is accessible. Two years ago I could not find any affordable router with at least one sfp+, now there is great choice
We will see more and more devices with such networking. I think 5G is death end, better than 2.5G, but most already jumped into 10G.

And GB6 multi-core scores are pure nonsense anyway.

That is why I was interested only in single core results.
BTW: it’s the first time I see board with big/medium/small cores, this makes GB multi core method even more nonsense.

@hipboi, thanks for the details, that makes sense now. Be careful however, on the public sheets it’s written at a few points “>100 GB/s” for the DRAM bandwidth, but that’s actually not the case, as DDR-5500 in 128 bits is 88 GB/s. Only the 6400 model (maybe CP8180) is 100 GB/s. Also on one of the BIOS screenshots it’s written “2.6 GHz” while the doc mentions 2.8 GHz, that may also cast some doubts. Regardless, the platform is super interesting in anycase

What uses those in Rock5B? USB

The Gen2 PCIe lanes on RK3588/RK3588S(2)/RK3582/RK3583 are all behind Combo Pipe PHYs and multiplexed with USB3/SATA. Situation with Rock 5B explained here.

Is there a microsd lot ?
