Simultaneous multithreading, i.e. more than one thread per core. The 9700k has 8 cores 8 threads, the 3700/800x has 8 cores 16 threads. It's a big improvement in performance in productivity applications, but games are already taking advantage of 16 threads today, and it will definitely be more important when next gen consoles will be 8c16t on the exact same architecture.
You can take today's games' results that push cpus to their limit using a gpu you'll never realistically own as gospel, but in my opinion it's short-sighted.
How long are you waiting? Is it rebooting over and over? You should let it power cycle for a while if you managed to flash the bios. If it definitely doesn't post after some time, then yes, try the newer bios.Thank you! I had all setup and...black screen, no signal...
I get light on the motherboard, the CPU spin is working, RAM is with led....GPU with led...
But...no signal. I have to flashback the bios again with the one at reddit ? Do you know if I can do flashback without disassembling all again ? Thank you !
Also, in theory, you can use flashback with everything mounted, it's supposed to work independently. But did you read that part about the reset switch? It's suped weird but it's worth trying if it's not booting.
