I don't like the sound of some of that stuff mentioned in that Reddit post, true or not. Particularly:-
I really hate software overclocking so I really hope this will not be true of the retail products. The bios has always been the best place to tweak overclocks. I also don't like the sound of not being able to update the bios and the fact that only AMD can is worrying.

I'll eat my hat if they release 5960x performance at £300. It's simply not going to happen.

No, they're saying it's with the bug fix disabled it's up there with Intel.
this all day.
look at 8 core amd cpus when released still slower than 4 core intel.the product is still not being shouted about.its gunna sit in its usual position and place.bargin.
if it was faster they would have priced it higher . price is key to the speed. it tells all.

AMD will still be behind in single threaded performance,so it will be Haswell level vs Skylake level. So they will have more cores for the same price to even things out.
I think the reality will be a 6C/12T Zen against a 4C/8T Core i7.
But looking at estimates of the core size,it will be a core not more than 200MM2 to 250MM2 at most. This means it will be around the same size as one in a RX480 or RX470. That alone will make margins FAR higher,even if they decided to sell an 8C/16T CPU at £300 to £350. That is around the price the Core i7 6700K is selling for now.

Its another 4 months until launch,so maybe this is why there is the delay from late 2016 to early 2017 for the launch as some pointed out here - maybe it is time needed to fix the bug??
I would rather AMD iron out any problems before launch TBH then rush it out.

Assuming what this article is saying is true' AMD don't have a good product to launch unless this bug is solved.
Otherwise they will be reduced to selling low numbers of power efficient FX CPU's with SMT for £70 to £150.
Read about the Phenom TLB bug. It would be a stupid hack job for them to release these chips with a software fix in place only (the one that neuters performance).
If it is as similar to the TLB bug as the reddit poster is lead to believe, they can reduce the performance impact greatly by introducing hardware-based fixes or eliminating the bug altogether.

What i'm saying is 'its that or nothing'.
Current FX CPU's with SMT are low margin low volume chips, a renewal of these
How can the BIOS/UEFI be stored in the CPU anyway? the only way it could work is if motherboards were all identical spec? if true it sounds like AMD are locking things down pretty bad.

Actually this is a really good point and for me adds more doubt on the article.
The BIOS is the Motherboards brain, it controls all the components on the motherboard and everything you plug into it, Storage Drives, Peripherals.....
Graphics cards.
Nvidia go to Asus with Volta, this is what you need to know to make it run in your boards, Asus need to go to AMD with that so AMD can write the BIOS for their boards?
Not happening.
Fan controllers, Board Vendor software for case fan profiles interact with AMD's firmware?
Not happening.
On-Board Audio, again control is handed to middle-ware in AMD's own firmware?
AMD nor any Board Vendors are going operate under such conditions, it adds insurmountable complications and costs.
Thinking about it this looks like fantasy, like something invented by someone with a view to create a few awkward room elephant rumours for AMD.
Which this and the TLB bug certainly do.
IMO its made up by a professional troll.

GPU's have a BIOS.
Why can't a CPU?
Not that I personally believe anything. A £300 pound 5960X is lol.

A CPU does not need to run VRM's, Memory IC's, fan controllers....... separate from those on the motherboard.
Caporegime
Missing my point.
A CPU could have a BIOS, while motherboard also has one (Controlling those elements you were questioning).
In doing so, giving the ability to lock down certain aspects of the CPU at BIOS level (Same as how a GPU has a BIOS, yet resides in a motherboard which also has a BIOS)
Caporegime
CPU's don't need their own BIOS for that, its not Intel's own CPU BIOS thats locking down none K chips.

Zen is a SOC though - it technically needs no chipset. But,OTH,I will have some healthy scepticism when it comes to an AMD launch - it would be nice if they pull of a good one though. If they get to Haswell levels of single threaded performance,that would be pretty impressive for them considering how much smaller than Intel they are,but it would mean either more cores for the same price or cheaper CPU pricing to compensate.
Caporegime
AM4 boards are not SOC.
