I do love those PCI-E lanes, but I am worried that the 24 core will actually be slower than the 16 core most of the time in "gaming" applications by being reduced to being a 3900x with 12 cores just resting.
This is actually not a huge concern for two reasons.

1) The non-active cores draw nearly zero power.
2) The 24-core have a massive TDP which means it simply won't matter anyway.

I'm not saying "buy the expensive thing", I'm saying that due to current Boost algorithms, they will likely perform exactly the same in lightly threaded loads.

And frankly, I have been very happy with the performance of my 16c/32t 2950X which has an extensive (ambient) water-cooling system. At 4.3 GHz all core, tight-timing DDR4 @ 3466 and decent scores (per spoiler), it probably would make an immediate upgrade to 24t TR3 not really worth it. 32C (or even a later if/when 64c with the TRX80 chipset ) would be more interesting.

In any case, I want to see some real world TR3 and latest Intel HEDT tests first, and also wait out the inevitable 'agesa' updates...if launch bios issues of X570 are any indication for the TR3 launch, 'wait-and-see' is probably a good idea. That said, if there would have been X399 compatibility, I would have been much more tempted to act earlier...

Personally I am hoping for a 16 core version. I know we have that on AM4, but I want/need more PCIE lanes and would prefer to have the quad channel memory to go along with it.

Well, TR4 socket saw first 16c, and then doubled to 32c.
Considering, that we can expect a 3990X as well, another core count doubling to 64c is .... problematic on the CPU pin side and power delivery.

Plus, the new chipset is insane and needs strong selling (point exists, but i guess they want to be sure???).

As far as I understand it, the socket itself will keep the same number of pins (even if wired differently) as well as heatsink & water-block compatibility with X399. From what I have read and seen on YouTube, an oc'ed 12nm 32 core/64 thread 2990WX can draw scary power already - then again the X399 Creation I use has one heck of a VRM. Also, the 7nm 64C / 128T TR4 apparently (?) needs yet another new chipset, at least re. 8 channel ram...

That is what I'm scratching my head about - I would have understood one separate 'new' chipset (TRWX80 or whatever it's name) for the 7nm 64C/128t...but with existing X399 boards running 12nm 32c TR2 already, 7nm 32C TR3 power consumption is not going to be the main issue. Perhaps there are other reasons (CPU to chipset bandwidth) necessitating TWO new chipsets, and braking compatibility with X399. BUT there's also the fact that Ryzen 3K (same chiplets as TR3) is backward comparable with X470 and even lower

A smarter play would have been, IMO, one new top-end chipset instead of two, and instead an upgrade path via X399 for 24c TR3 and up to 32c TR3.

Its actually ampers per pin. They are following some standard on this presumably. We will see how many pins the difference is. This way, they are keeping the BIOS under control as well.

Imaging having the CPU code being able to work with the old and the new chipset. Its going to be a mess.

I really can't say much other than, you won't be disappointed. I'm literally comparing CPU-Z and CB R20 against @J7SC 's right as I type this. I feel this is going to be a long wait until the 25th for me lol

What about light threaded work? Will we still be not dissapointed?

I am trying to figure out if I should dump money on x570 extreme and aim for 3950x or set sights at trx40 extreme and 3960x.

Mostly gaming here, but I do love my pci-e lanes

Threadripper is for playing cinebench 24/7

If it had low latency like x299 cpu's when overclocked ~50ns, we would have known already 🙂

Tr3 cpu's can't have lower latency than Ryzen gen 3, so....

Well, just pointing out that the 2950X is a 16 core, not a 24 core...2970WX 24 core TR2 would be a direct comparison to your TR3 3960X CPUz (btw, just wondering a bit about the voltage @ 4.1). I figure at 'stock speed', whatever that will be, the 24 c 3960X should do Cinebench R20 at around 14,300 to 14,500 'multicore', and around 504 to 510 'single core', depending also on bios, ram etc. Close ?

Also, re. your 'silence' issue I ftfy

Taking in mind that the TR4 socket has 900 reserved pins they can do pretty much whatever they like with it and even leave some more in reserve for another iteration.
