CPU Basics: Multiple CPUs, Cores, and Hyper-Threading Explained By: Chris Hoffman Updated Oct 12, 2018 The central processing unit (CPU) in your computer does the computational work—running programs, basically. But modern CPUs offer features like multiple cores and hyper-threading. Some PCs even use multiple CPUs. We’re here to help sort it all out. The clock speed for a CPU used to be enough when comparing performance. Things aren’t so simple anymore. A CPU that offers multiple cores or hyper-threading may perform significantly better than a single-core CPU of the same speed that doesn’t feature hyper-threading. And PCs with multiple CPUs can have an even bigger advantage. All of these features are designed to allow PCs to more easily run multiple processes at the same time—increasing your performance when multitasking or under the demands of powerful apps like video encoders and modern games. So, let’s take a look at each of these features and what they might mean to you. Hyper-Thr...

  Intel Core i7-1280P The  Intel Core i7-1280P  is the flagship Alder Lake-P CPU, which is to say, an expensive 28 W part meant for use in ultra-light (yet actively cooled) laptops. This CPU was announced in early 2022 and it has 6 performance cores (P-cores, Golden Cove architecture) mated to 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled for whopping 20 threads when combined with the E-cores. The clock speeds range from 1.8 GHz to 4.8 GHz for the performance cluster and 1.3 GHz to 3.6 GHz for the efficiency cluster. This is the only hexa-core 28 W Alder Lake CPU as of February 2022, trumping what the more affordable  i7-1270P  and  i7-1260P  have in store. Full vPro feature set is supported by this Core i7 ("Enterprise" tier, allowing for remote device management). Architecture The i7 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "little"...
