E cores?

[R3dAlert93]

Is it recommended to disabling E cores for some games?

[_I_]

some games, yes

they are slower than the p cores, and if windows scheduler decides to run the games on them, then it can reduce game performance/fps

See if your bios has the setting that allows you to toggle the e crores using scroll lock rather than turning them on and off in the bios. Then you can quickly turn them on or off and see if game performance changes.

I got an asus Z790 motherboard and cannot find them. Tried searching "turn off e cores in asus bios" on google and it does not have anything they mention in the bios.

-Go into the UEFI
-select the "Advanced" tab
-select "CPU Configuration"
-scroll down and select "Legacy Game Compatibility Mode"
-set to "Enabled"
-Save and Exit
-Use "Scroll Lock" key to park or unpark "e" cores.

In most games it doesn't make a difference and it hurts in just about as many games as it helps. You might do it if you're really into one of the few games where it's known to help, but otherwise I wouldn't bother. Plus e-cores are used for A.P.O. in 14th gen. processors.

So is it better to get 14700K to avoid frame drops in certain games?

intel dropping e cores and ht on newer gen cpus should tell you something

It's pretty hard to recommend a raptor lake chip in light of all that has been happening lately, esp. if we see Arrow Lake processors in October. A.P.O. is only used in Rainbow Siege Six and Metro Exodus so far, with possible support in future games. Plus it's an Intel feature. I'd worry about future games in a future upgrade if the feature takes off.

Regarding e-cores in general, Steve Walton suggested using Process Lasso[bitsum.com] to restrict which cores the games access on a per game basis. That way the e-cores are still enabled to help handle background tasks.

Couldn't tell you much more than that.

disable hyperthreading too

You might wanna research that. Core 7 is getting rid of HT only. the new Core 7 will have 20 cores.

8 P cores and 12 E cores.

I have a 13700K and it doesnt seem to be a massive increase to justify a new mobo and cpu.

Also I had the 9700K, it was amazing for the price, but the lack of threads, 8 threads 8 core no HT made it run like trash in many games, and murdered any ability to stream, without the cpu hitting 100% cpu.

Games like Jedi Survivor & Icarus caused me to make the jump to 13700k The 9700k went out dated way too fast. The lack of HT and thread count killed it's longevity.

The new core 7 265k is set to be fast, and run cooler, but I dont think it will last as long(in terms of performance vs new games releasing) The lack of HT and no additional P cores makes it a sleeper imho

im running the 13700k with all p and 3 cores no overclock no undervolt. Just stock turbo. 4k 144hz, runs well, unless I fire up Star ♥♥♥♥♥♥♥♥, then I need to kill my e cores.

You can leave all cpu features on and just use an app called CoreDirector that allows you to add exe to the list so that only those won't use the E Cores

Whats An E-Core Ryzen Or Bust

It's Intel's name for a 4c core. :-P

never had 1 issue with Ecores in any games to date..but then again seeing as your
GPU does most of the work nowadays this seems insignificant at best.
