리눅스 쪽 커널엔 전력 제한 등이 어느정도 소개되어 있어서 (ex PL2 180W 등등)
실구동기가 언제쯤 포착될까 기다렸는데, 이번에 포착된 듯 합니다.
E코어 클럭도 대략적으론 공개되었다보니 얘가 확실하게 샘플이 맞긴 할텐데, 결국 하이엔드에 HT가 없는 코어 i 시리즈 최초의 라인업이 될 듯 합니다.
n Intel 15th Gen Arrow Lake CPU has been spotted in the Linux GNU (courtesy: InstLatX64). Featuring 24 threads with a base clock of 3000MHz, we’re likely looking at the Core i9-15900K or the Core Ultra 9. The fact that the thread count is the same as the core count means that hyper-threading is missing, and with no mention of Rentable Units, Arrow Lake will be a unique lineup, to say the least.
Hyper-threading may have been disabled from the BIOS, but this would be the second time we’ve seen an Arrow Lake sample without active hyper-threading. The previous sample (leaked by YuuKi_Ans) was also a 24-core (8P +16E) chip with no hyper-threading, a 3.5GHz base clock, and a 125W TDP.
The interesting question is whether Arrow Lake will architecturally support hyper-threading, and if so, will it be disabled from the BIOS like AVX512 on early 12th Gen chips? The decision to remove SMT without a suitable replacement feels unnecessary. Was hyper-threading removed because it didn’t provide any tangible performance advantages or because early plans for Rentable Units didn’t pan out?
