The arm architecture is ridiculous in performance and this arm cpus seriously depends on others accelerators to final purpuse, these accelerators are still on construction(Libre) to be enabled in the Librem 5. Asking for another phone with a better CPU is falling into the same hole again and start again.
Fir it is super super super import on the same SOCompat.

Fir is a batch though, not a version. The differences between batches A through E are relatively minor, and if Fir comes into being, the same may be true again. That may not accord with the expectations of those who have deferred their order to the Fir batch however.
The Librem 5 v2 is a whole different (hypothetical) device. The Librem 5 v2 has unfortunately, in this forum, also been misleadingly named the Librem 6.
… so the extent to which Fir would slow development depends on what Fir encompasses.
A possible compromise: Fir is Evergreen but with the 4GB RAM upgrade and/or the 128GB eMMC upgrade (whatever is most practical without disrupting things).
One unknown for us as outsiders is … how many phone orders are in the Fir batch?

Purism is in no position to dump what they have learned making the Librem 5 and starting from scratch. Samsung, sure they have very very deep pockets.
I think the main thing with the Fir batch is if they can improve the battery life/power management, network reliability (modem/bluetooth/wifi) and perhaps figure out a way to shrink the footprint a bit so it’s not quite so hefty, like a weight loss program.
These further refinements to the existing platform will set them up nicely for a next full revision of the device, but like I said there is really no starting from scratch here unless they get some sort of windfall of money in which to do so.

Interesting. The chip can do “up to” 2.3TOPS (int8).

I havent seen anything from Purism to support this claim.
I dont think were going to know what Fir will contain until theres an official announcement, and I suspect that there will never be an official fir batch but rather a new product, a Librem 5v2 or something similar as the amber - evergreen batches has too much baggage to keep with that naming scheme and it is more beneficial to the business to avoid the sins of the past where possible.

Yes, looks pretty speculative.

Not going to lie, I think if Purism was selling a version of the Librem 5 with 8+ GB of ram, a much faster processor, and a marginally better camera, I would probably throw like $5000 at it just to keep using this style of handset while getting marginal improvements.
If I had any financial advisors, they would probably tell me I was being extremely unwise, but luckily I probably won’t tell anyone acting in that capacity for me in the future about this behavior

Just bedazzle your present L5 with jewels if you feel like spending so much.

I think i would rather bedazzle it with the corpses of my previous android phones, ripped out from their circuit boards, just for the off chance that they might cause it to run faster
Edit:
How much faster does a Librem 5 run if it has the processor from a samsung ripped off its circuit board and glued to the L5 for inspiration? maybe that’s the question i should be asking

What you may really want is a die shrink i.e. smaller process fab - so that even with the same speed of processor, you get reduced power consumption, and hence a longer time to deplete the battery. That’s not to say that someone might not also welcome a faster processor but then I would also welcome a faster disk.

I think with a faster processor (smaller process fab) I would prefer a setting where I can choose between performance mode and speed mode. This way I could do more heavily tasks when I’m not out of power (i.e. on desktop) while extending battery uptime on a trip.
The camera is the only thing that sounds realistic for now. 
But the camera will also make better pictures with further camera app improvements. Anyway, it would be nice to get improvements especially for dark environments.
For 8GB of RAM the processor has to support it. And for a better processor (beyond what was or is the plan for Fir, which only supports 4GB RAM if I’m not wrong) Purism needs to find one where proprietary blobs wont be a thing plus with an available FOSS firmware. The requirements are high as you can see.

Is there any news on the Fir batch?
I read Purism news from time to time to see if I am to expect my phone any time soon but I haven’t read nothing about the Fir batch (though it’s possible I missed it).
Has Purism communicated anything about it? Is it still expected to happen? Is it possible to fallback to an Evergreen phone otherwise?

No.
Depends on whom you ask.
Likely, you’d have to email purism support to find out for certain.

I would say very likely but only Purism can say for sure.
I would also say that, given the absence of news on Fir, this might be a sensible course of action. I guess it depends on your goals and your personal situation.

Make Librem 5 more Delicious on Fir.
- Add LTPOLED HD-HDR 90HZ monitor.
- Add G Master Mobile Lens to delete Aberration from root.

The options for Purism are:
- Keep the i.MX 8M Quad processor, but offer 4GB RAM and 256GB Flash.
- Switch to the i.MX 8M Plus processor, which is both an upgrade and a downgrade
- Upgrade to the i.MX 95 processor.
- Switch to the Rockchip RK3566
- Use a down-clocked Rockchip RK3588.
- Accept the blobs and use a Qualcomm QCM6490
If Purism wants to sell the Librem 5/Liberty as a convergent PC, it should consider option 1, but it doesn’t address the poor battery life, high heat and poor processing power of the i.MX 8M Quad.
Honestly, the amount of engineering for options 2, 3, 4 and 5 is significant and I doubt that Purism has the financing to attempt them, because I don’t think Purism can ever do another crowd funding campaign due to the bad publicity it received from the crowdfunding of the Librem 5.
Switching to the i.MX 8M Plus would shrink the process node from 28 to 14 nm and reduce the heat, while improving the processing power, but it cuts the GPU processing power in half and eliminates the video out with USB-C DisplayPort Alt Mode (although a separate chip could be added to provide that). I have no idea if the NPU in the Plus can be run without blobs, but the Librem 5 doesn’t need an NPU in my opinion.
I’m really annoyed that none of the chipmakers are bothered to make a competitive Linux chip for phones, except Qualcomm, and you need a bunch of blobs to run the QCM6490. However, I don’t see much difference in terms of freedom between running blobs on separate WiFi and cellular modem chips and running blobs on an integrated SoC like the QCM6490, although there are security/privacy differences because you can cut the power to those chips with hardware kill switches.
The 8nm RK3588 with four Cortex-A76 and four Cortex-A55 cores is a fantastic chip for a Linux laptop, and maybe it can be downclocked to fit within the power envelope of a phone, but that will give you a hot phone with a short battery life, like the PinePhone Pro, which is hardly ideal. The performance of the 22nm RK3566 with four Cortex-A55 cores with a max of 8GB RAM isn’t very impressive, and I don’t see much point in Purism using the chip when PINE64 says that it will use the chip in the PinePhone 2. There is no way that Purism can compete with PINE64’s low prices, and the chip doesn’t have good enough performance to bother, and you need blobs to boot the Rockchip chips.
It kills me that NXP gave the 12nm i.MX 95 six Cortex-A55 cores, but not a single Cortex-A78 core. NXP seems to have purposely crippled the performance of the chip, but it still looks like the best option to me.
Another option is for Purism to go to Fairphone or SHIFT and work out a deal to sell a Linux phone with their hardware containing the QCM6490 chip. Of course, it would have to run blobs on the main processing cores. I can’t see Purism doing that, because it goes against the company’s ethos and brand image, but I would love to see the company do it, because we really do need a Linux phone that can be used as a full Android replacement. The advantage of this option is that Purism could roll it out quickly and it wouldn’t require that much investment.
Given the financial realities of the company, I think that Purism should do both options 1 and 6, because both can be done for limited investment, and I think both would be profitable. Purism would be able to offer one phone for people who want the freest phone possible and a convergent desktop, and it can offer another phone for people who want a decent camera, good processing power, good battery life, etc. to replace their Android phone and don’t mind the blobs.

I’d like to add that for future endeavors, a preferred modem family should also be selected. There are now more options available than before but they can be finicky and need support - and instead of one single supported modem, a family line would be better. Some future proofing for “LTS phone”.
As far as I’ve kept track (which is not as extensive as some), I think the Quectel line (what was already tested via EM12-G and was preceded by EM060-GL) would be a good fit. There already exists linux support and the line (meaning here variations that use the same size and commands but have increasing features) has variants for different levels of use and price ranges. The current L5 size (which could also be made bigger to allow for current and bigger sizes) doesn’t have a full 5G card at the moment but there is new RedTop-17 spec model that may allow for upgrading to 5G already - and it seems likely there will be future models. I think this is important for the longevity but also to give options for upgrading the modem, from about 40 to 400 coins (€,$,£).
As has been seen, options in this area are needed, but they also need support to get full and perfect use, and that is why a clear choice would be good for concentration of efforts (while not excluding any other potential modems… or any other cards used in m.2 slots). Newer modems would also help a bit with battery life. I’m not aware if there are any major differences in “blobbiness”, but that should be moot, given L5 structure. 4G antennae is the minimum and alternative choices could be to include 5G regardless of modem (or even pre-emptively option for even 6G [the additional freqs at around 7Ghz, not all]) or develop a changeable back cover that has that additional antenna (but that’s theoretical and a bit iffy).
