Introduction – Intel Core i7 14700K assessment
We assessment the Intel 14th Gen core processor, particularly the Raptor Lake-based Core i7 14700K, which has been formally launched. Maybe this is among the extra attention-grabbing processors to buy within the new Raptor Lake refresh sequence, as except for clock frequency tweaks, this CPU additionally receives 4 additional vitality cores, and that’ll matter in multi-threaded efficiency.
The processor is a refresh based mostly on the 13700K(S) and boasts a velocity of as much as 5.6 GHz and a configuration of 20 processor cores. These are organized based mostly on 8 efficiency cores (P-cores) and 12 effectivity cores (E-cores), supporting as much as 28 threads. For optimum performance, the Intel Core i7-14700K necessitates an Intel Z790 or Intel Z690 chipset-based motherboard. The Core i9-14900K is taken into account Intel’s flagship processor on this sequence, second greatest is the Core i7 14700K. Moreover, anticipated are KF variations of those processors, mirroring their Ok sequence however excluding an (lively) built-in GPU.
Traditionally, Intel talked about the Tau parameter in relation to PL1/PL2. Nevertheless, with the debut of the twelfth Gen Processors, PL1 and PL2 have equivalent values. Consequently, it is redundant to outline the period the CPU will maintain at PL2 earlier than transitioning to PL1 since each the lengthy and short-duration energy values are actually the identical. This processor’s base energy draw is 253W in case your motherboard producers configures it at default. Sure the TDP for the top-end merchandise has been elevated to 253W for each PL1 and PL2 states. There are 28 cores (8P+12E) and a bunch of MB of mixed L2 and L3 caches. This SKU’s highest increase frequency is 5.6 GHz, and will probably be accessible with built-in UHD Graphics 770. Carrying an MSRP of $409 this could be a very attention-grabbing SKU to buy.

Raptor Lake processors characteristic 2MB L2 cache per P-core, whereas Alder Lake processors have 1.25MB per P-core. The CPUs have 4MB of L2 cache per E-core cluster, up from 2MB beforehand. Moreover, the entire quantity of L3 cache is 36MB. Intel claims a 15% enchancment in single-threaded efficiency and a 41% enchancment in multi-threaded efficiency. These enhancements are primarily the results of increased frequency and thread depend. The Z790 high-end platform from Intel options many PCIe Gen4 lanes and USB 3.0 Gen 2×2 20 Gbps ports. On this assessment we’ll tackle the flagship Core i7 14700K; it has eight efficiency cores (16 threads) and 12 Vitality pleasant cores (no hyperthreaded) providing you a pleasant 28 threads.
