Are the instances that HT off is faster purely faster at same static frequency, or are the chips boosting higher due to lower temps with HT off?

Just speaking for myself, I use a static overclock and so my frequencies are all the same. Something something about the thread pipeline being less congested with HT off, which can benefit games that aren't very well optimized. Not gonna pretend I fully understand it though lol.

I'm currently running a 14900K with HT off. 8+16.
I mostly game and do some music projects through a DAW. With HT off, I was able to easily do +100MHz on the P cores compared to HT on for Cinebench and OCCT with a nice reduction in power and temps. I saw like 320W peak running R23 at 1.270V load with 59/45/49, mostly sitting in the high 200s. Scored like 36000. I don't really have worry about shader compilations pulling crazy power. Not much of a difference in gaming in terms of power draw, which isn't surprising. If a game needs more than the 8 threads from the P cores, it will just go to the e cores.
I am assuming the Windows 10 that I am using is smart enough to put the heavier tasks on the P cores based on the clock speed differences between the core types, because I have zero stuttering issues and performance has been great. I had horrible stuttering in some games with Windows 11, but I seemed to fix that when I unparked the ecores. Too much of the UI changes for Windows 11 annoyed me so I went back lol.

You must have clock stretching going on cause at 5.6/4.5/4.7 ht off i score 36000-36200 in cb23.

12700k, never bother turning off HT as I havent had any issues with applications or games.

I'm trying to understand this. With HT on, a stock clock 14900K will score 41K+ in R23 at 260-270W with an aio.

So I believe your purpose is to have 59x multicore for improved gaming performance? But without HT, game will have to offload more to the ecores? So is there really an improvement?

260W with a 14900K running stock on an AIO for R23?

Games won't use HT if e-cores are available. Might not use HT even with e-cores disabled, haven't tested that.

HT won't increase performance that much if you have a power limit set. It's only 7%.

Dude you have set PL1 and 2 at 220W... That's why you are not seeing much difference between HT on vs off in Cinebench.

SebastianFM said:
btw, I have no idea why the CPU temperature is higher when HT is enabled.

HT on makes the CPU hotter yes. Allways been this way.

I just turned HT off, i don't see any difference in games, but i have lower temps, not that they were any problem but still nice.

Power usage may be lower, but power efficiency is also lower as well. You get less performance-per-watt with hyperthreading off.

That may be true for workload scenarios, but its the opposite for games. I can clock higher for lower wattage while getting better performance clock for clock in games. Since I don't ever run any productive apps (this is strictly a gaming PC), HT off is best for me :cool:

HT off should be the go-to for gaming. It's just that having 8 extra threads for Windows may be a good idea. By the time Intel releases a CPU with 16 pcores and 32 ecores, it won't matter as much since you got a 48 thread CPU anyways then...

Maybe check what you quoted, dude. 😉

It's the case. HT increases performance but not for free, it consumes more power.

In both cases power consumption was the same due to limits.

Best gaming config is 8c/8t with 8 e-cores 👊

Cinebench creates it's own threads and sets affinity programmatically which ignores whatever you configure in task manager. Don't remember implementation details. If there's a way to go around this I don't know other than going into the UEFI and disabling the cores you don't want to test.

Also at least R23 does a good job at prioritizing core selection for performance.

That proves my point even further.

Something is definitely wrong with your Windows.

Nope, brand new Windows install from scratch. Lots of people have had similar or other types of issues with E-cores the past 2 or 3 years since they were introduced with 12th gen (Alder Lake).
