However, they didn’t differ much from each other, featuring just a few tweaks here and there, and the new AI features that the 14900K came with. However, out of all the three CPUs, it was the i7 lineup that got some serious upgrades at the hardware level.
Unlike its i9 and i5 counterparts, the Core i7-14700K stands out as the biggest winner in this refresh. Previous i7 models have seen increases in CPU core count with each generation, and the 14700K continues this trend.
Like the 13900K, the 14900K came with 24 cores, of which 8 were Performance cores and 16 Efficient cores.
Similarly, the 14600K, much like the 13600K came with 16 cores, of which 6 were Performance cores and 8, were Efficient cores.
The 13700K of the previous year, boasted 8 Performance cores and 8 Efficient cores, summing up to 16 cores. This time around, Intel has given the i7-14700K a boost with 8 Performance cores and 12 Efficient cores, making a total of 20 cores. Not to forget, the number of threads has also been bumped up to 28.
In essence, Intel’s Core i7-14700K emerges as a significantly more potent chip compared to its predecessors in the i7 lineup, all thanks to those extra 4 Efficient cores. Now, the burning question: How well does it perform?
Intel Core i7 14700K Review: Specifications
The Raptor Lake Refresh silicon keeps to the Intel 7 process node, just like its predecessor. Physically, it boasts 8 Raptor Cove P-cores (performance cores) and 16 Gracemont E-cores (efficiency cores), arranged in 4-core clusters.
Sharing a 36 MB L3 cache among the P-cores and E-core clusters, each P-core has a dedicated 2 MB L2 cache, while each E-core cluster shares a 4 MB L2 cache among its cores. Crafting the i7-14700K from this die involves activating 3 out of 4 E-core clusters, resulting in a chip with 33 MB of L3 cache.
Beyond the core count, the Core i7-14700K also sees a slight uptick in clock speed compared to the i7-13700K. The P-cores start at a base frequency of 3.40 GHz, reaching a maximum boost frequency of 5.60 GHz using the Turbo Boost Max 3.0 algorithm – a 200 MHz increase from the previous generation.
The E-cores experience a modest bump in clock speed as well, with a 2.50 GHz base frequency and a 4.30 GHz turbo frequency. Notably, Core i7 chips from the last two generations have enjoyed power limits on par with their Core i9 counterparts. The i7-14700K maintains this trend, boasting a maximum turbo power (MTP) of 253 W, matching that of the i9-14900K. With one less E-core cluster to cater to, there’s a slightly enhanced boost residency for all cores.
In terms of memory, the 14th-gen Raptor Lake Refresh processors support DDR5 at a speedy 5600MT/s. However, the processor is also compatible with DDR4 memory, albeit at speeds up to 3200MT/s.
The flexibility stems from the fact that the new generation shares the same LGA1700 socket design as its predecessors, making it compatible with motherboards that support the 12th-gen and 13th-gen CPUs.
Furthermore, the 14th-gen introduces support for PCIe Gen 5 and Wi-Fi 7, enhancing connectivity options for users.
