Delid do 7700K e uma melhoria de mais de 20cº em load. é mesmo impressionante como a TIm que a Intel usa nestes CPUs é tão má.

Segundo a PCGH, vão haver quad-cores na próxima plataforma "extreme", sem iGPU.
i5 7640K e i7 7740K em socket 2066.

Critical hyper-threading flaw discovered in Kaby Lake and Skylake chipsCitação:
With Intel finally facing a challenge from AMD in the high-end processor market, the discovery of a major Hyper-Threading flaw in both Kaby Lake and Skylake CPUs would be a most unwelcome problem for Chipzilla. Unfortunately, that’s the scenario it’s now facing.
The issue, which can destabilize chips and lead to unpredictable system behavior, data corruption, and data loss, was described on the Debian mailing list following earlier work by OCaml toolchain developers. It affects Skylake and Kaby Lake Intel Core processors (in desktop, high-end desktop, embedded and mobile platforms), Xeon v5 and v6 server processors, and some Pentium models. And while Debian is a Linux distro, the problem can appear on any operating system.
This is how Intel’s errata documentation describes the flaw.
Under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers as well as their corresponding wider register (eg RAX, EAX or AX for AH) may cause unpredictable system behavior. This can only happen when both logical processors on the same physical processor are active.It's worth noting that the exact replication conditions, which aren't clear, are unlikely to be encountered by most users, but debian.org still recommends disabling hyper-threading until a microcode update is applied. Intel has reportedly issued some fixes, but they need to be integrated into motherboard BIOS/UEFI updates.
The Debian notes says that “You want your system vendor to provide a BIOS/UEFI update that fixes Intel processor errata KBL095, KBW095 or the similar one for my Kaby Lake processor.” It recommends Skylake users contact their system vendor for an update that fixes "Intel erratum SKW144, SKL150, SKX150, SKZ7, or the similar one for my Skylake processor".
Back in May, Intel responded to i7-7700K high-temperature issues by telling owners they shouldn’t overclock the chips. It’s a problem TechSpot's features editor Steve Walton touched on this in a video for Hardware Unboxed back in February.
Boas!
Outch...
Estava mesmo a ler um artigo sobre isso...
Até recomendam desactivar o HT nesses cpu´s...
Cumprimentos,

Lembras-te desta resposta da Intel:
Intel tells Core i7-7700K owners to stop overclocking to avoid high temps
Nunca mais compro nada desse lixo. Long live AMD.
"...e então a Intel passou a fazer motherboards para competir com a biostar, e ssd para competir com a Adata filho..."
Que tempestade num copo de água... numa coisa que já está resolvida ou em vias de estar.
Citação:
Under certain conditions, systems with Skylake or Kaby Lake processors can crash due to a bug that occurs when hyperthreading is enabled. Intel has fixed the bug in a microcode update.
Isso por conta do delid né filho xD
Atualiza mazé essa assinatura, não vejo nenhum 7700k aí :P
Então mas o CPU já anda aí há tanto tempo, e só agora é que viram que há problema? E isto porque um desenvolvedor do Debian reparou? Será que o problema é assim tão grave? Ou é o pessoal que gosta de exagerar e arrumar polémicas? Porque até agora, tirando a questão de ser um chip quente (que já o meu 4790k era e bem), todos andavam felizes com a performance e grandes clocks.
