: 英特尔11代酷睿处理器对于普通消费者来说吸引力不足，因此很多人对此并不感冒，特别是发烧友更是如此，其中一个巨大的原因就是大家都在等英特尔12代酷睿处理器。据悉这款处理器将会是英特尔首款采用大小核架构的产品，目前网上曝光了12代酷睿处理器的跑分，从跑分来看，12代酷睿处理器的性能要比AMD目前的锐龙9 5950X出色地多。

: 根据曝光的消息，目前英特尔酷睿i9-12900K处理器的跑分基于QS版本，同时没有进行超频处理，而散热则采用了水冷进行散热，从而确保CPU能够发挥最佳的性能。在CineBench R20这款软件中，Intel Core i9-12900K处理器的单线程跑分为810分，多线程得分为11600分。而目前AMD锐龙9 5950X处理器的单线程得分为650分，多线程得分为10428分，也就是说Intel Core i9-12900K处理器的单线程得分提升幅度为25%左右，而多线程得分提升为11.2%。

: 这个成绩相比较目前的处理器来说提升巨大，特别是单线程性能，更是拥有25%的成绩，不过也有消息称英特尔今年的处理器专门为跑分优化，所以实际游戏体验究竟能够到达怎样的水平，还是需要等到正式版处理器出来才知道。此外也有消息称英特尔计划在12代酷睿处理器中默认关闭AVX512，从而在测试中取得更好的成绩，并且想要让12代酷睿处理器发挥最出色的性能，Win11系统不可缺少。

: With qualification samples of the upcoming Intel Core i9-12900K "Alder Lake-S" processors and companion Socket LGA1700 motherboards hitting the black-market, expect a deluge of benchmarks on social media. One such that stands out makes a fascinating claim that the i9-12900K beats AMD's current flagship Ryzen 9 5950X processor at Cinebench R20, which has been AMD's favorite multi-threaded benchmark. At stock speeds, with liquid cooling, the i9-12900K allegedly scores 810 points in the single-threaded test, and 11600 points in multi-threaded.
:
: To put these numbers into perspective, a 641 points in the single-threaded test, and 10234 points in multi-threaded, in our own testing. The i9-12900K is technically a 16-core processor, just like the 5950X, but half its cores are low-power "Gracemont." The "Alder Lake-S" chip appears to be making up ground on the single-threaded performance of the "Golden Cove" P-core, that's a whopping 25% higher than the "Zen 3" core on the 5950X. This is aided not just by higher IPC, but also the for 1~2 cores, and 5.00 GHz "all-core" boost (for the P-cores).
:
: Given the multi-threaded scores, it's safe to assume that either Intel or Microsoft has figured out a way to leverage the P-cores and E-cores simultaneously in peak multi-threaded workloads. This is possible when both the "Golden Cove" and "Gracemont" cores have the ISA capability needed by the workload, which in case of Cinebench R20, is AVX. "Gracemont" is Intel's first low-power core to support AVX, AVX2, and AVX-VNNI instruction sets. "Golden Cove" features a more lavish ISA that includes AVX-512 (select client-relevant instructions).
