Go to solution Solved by Jurrunio,

8 core 8 thread versus 6 core 12 threads, equal same all core performance. It's more of a choice between 'more expensive factory-delidded CPU', or 'cheaper CPU you have to delid yourself, or suffer from poor thermals'.

quick question would the i7-9700k be better for gaming or would the i7-8700k be better as the i7-8700k has hyper-threading. where as the i7-9700k does not.

 

Many Thanks

Some games support hyperthreading and some don’t, most games don’t from my experience. That said the 8700k is the extremely better value considering most games prefer a more powerful gpu vs a cpu

CPU: Intel core i7-8086K Case: CORSAIR Crystal 570X RGB CPU Cooler: Corsair Hydro Series H150i PRO RGB Storage: Samsung 980 Pro - 2TB NVMe SSD PSU: EVGA 1000 GQ, 80+ GOLD 1000W, Semi Modular GPU: MSI Radeon RX 580 GAMING X 8G RAM: Corsair Dominator Platinum 64GB (4 x 16GB) DDR4 3200mhz Motherboard: Asus ROG STRIX Z370-E Gaming

They're equal in gaming, the 9700k is just easier to overclock high out of the box

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

They should be compareable in gaming, Hyper threading adds ~30% performance compared to non HT, and the 9700k has 33% more cores.

The main difference I would look at is price/availability and if you want to overclock/delid.

If you are are not willing to delid then I would go with the 9700k as 8700k thermals are not great without it.

Yeah, i don't/not willing to delid (not experienced). so i probably going to go for the i7-9700k
