The Core i7-14700K processor is the only 125-watt model from the Intel Raptor Lake-S Refresh generation that has undergone a core configuration change between generations. With more “efficient” ones, this processor is halfway to the Core i9-(14900K\/13900K<\/a>), but at the price of a Core i7. The Ci7-14700K is thus significantly more powerful than the Ci7-13700K for the same money. Especially in heavy multi-threaded workloads.<\/p>\n

Intel Core i7-14700K in detail<\/h2>\n

Although the architecture of Intel’s desktop processors based on the big.LITTLE concept hasn’t changed since the first generation (Alder Lake), the latest Core i7-14700K is already better equipped than the Core i9-12900K<\/a>. In addition to the eight P cores, it has twelve E cores instead of eight (Ci9-12900K and Ci7-13700K).<\/p>\n

The Core i7-14700K physically uses an 8E+16E chip (stepping B0) just like the Core i7-13700K<\/a>, but has more active E cores, as many as twelve. That’s four more compared to its predecessor, and four less than the top model in the form of the Core i9-14900K.<\/p>\n

\"\"<\/a><\/p>\n

Recall that Intel processors combining the Golden\/Raptor Cove<\/a> and Gracemont<\/a> architectures in the Core i7 class started with only four efficient cores total (12700K<\/a>). Thus, the advance in performance can be expected to be significant, especially for multi-threaded applications that can benefit from the large increase in the little cores. But it should also be taken into account that the all-core boost of the Core i7-14700K on the big cores is already 5.5 GHz, which is beneficial for gaming performance, among other things.<\/p>\n

The single-core boost for single-threaded applications, on the other hand, has climbed to 5.6 GHz, which is +600 MHz compared to the Ci7-12700K and +200 MHz compared to the Ci7-13700K<\/a>. Compared to the Core i9-13900K<\/a>, however, the Core i7-14700K still lags behind by 100\u2013200 (TVB) MHz. However, it’s important to note here that the Core i7-14700K came with a 180 USD lower MSRP, which is on the same level as the older model. Sure, compared to rival AMD’s Ryzen (7900X<\/a>) processor, Intel’s isn’t significantly cheaper in stores, as indicated by the MSRP, which each company sets a little differently, but even so, the direct confrontation is noteworthy. Intel comes with a higher core count (20), though more than half are “weaker” than the Zen 4<\/a> cores in the Ryzen 9 7900X<\/a>.<\/p>\n

\"\"<\/a><\/p>\n

As with all Raptor Lake Refresh processors, however, Intel has pushed the clock speeds harder in this case (Ci7-14700K) as well, even when it comes to the E cores with 4.3GHz for an all-core boost. Meanwhile, the PPT is still 253 W (as with the Core i7-13700K as well), but the power draw without power limits will naturally be higher with the Core i7-14700K. Compared to the R9 7900 (with a PPT of 230 W) quite significantly, but that’s getting into the results a bit too much. Which processor excels at what and which processor pulls the short end of the stick is traditionally a question for the next 39 chapters of this article.<\/p>\n
