The brand new Intel Raptor Lake Refresh CPUs are on the way in which for desktop fanatics. Whereas these new 14th Gen processors use the identical structure as thirteenth Gen, enhancements and optimisations to design have led to enhancements within the last product. One such enchancment is decrease voltages to succeed in most speeds.
The Intel Raptor Lake Refresh is a modest improve, together with higher speeds and further cores for the brand new Core i7 SKU. To this point, Intel has launched six desktop CPUs, all of that are a part of the 125W Okay-series. Igor’s Lab has examined a number of of those CPUs to see how totally different they’re from the older Raptor Lake chips.
Mifcom, a German PC retailer, provided a sampling of 600 CPUs for the testing, which was run by a gaggle of overclockers. As anticipated from a 600-sample check, nobody evaluated particular person processors. Nevertheless, some fundamental examinations could also be completed shortly utilizing accessible instruments. The exams had been carried out on an Asus Z790 ROG Maximus Hero motherboard with BIOS 1402. Folks doing these exams report SP (Silicon Prediction) scores for P-Cores and E-Cores and voltage on the highest claimed frequency (for the 14900K, that may be 6.0GHz). The outcomes will be discovered within the desk beneath:
| CPU | P-core SP | SP max | SP min | VID at Fmax | Fmax |
|---|---|---|---|---|---|
| i9-14900K | 108.6 | 121 | 99 | 1503 – 1398 | 6.0GHz |
| i9-14900KF | 105.6 | 115 | 99 | 1503 – 1423 | 6.0GHz |
| i7-14700K | 72.2 | 81 | 67 | 1433 – 1363 | 5.6GHz |
| i7-14700KF | 78.3 | 91 | 67 | 1433 – 1319 | 5.6GHz |
| i5-14600K | 68.3 | 90 | 48 | 1393 – 1208 | 5.3GHz |
| i5-14600KF | 67.8 | 88 | 53 | 1369 – 1214 | 5.3GHz |
Probably the most intriguing topics for this technology of Core i9 CPUs is the distinction between the Core i9-14900K and the Core i9-13900KS, which have equivalent configurations and clocks. The overclocking crew tried to determine this by evaluating the batch of i9-14900K(F) they’d at hand with a batch of i9-13900KS chips manufactured in 2023. This assures that there’s little to no variation throughout exams.
Based on the outcomes, the i9-13900KS wants 1493mV within the worst-case scenario and 1433mV within the best-case situation. In consequence, though the newest CPUs look superior, it is value noting that the Core i9-13900KS batch represents simply one-tenth of the i9-14900K(F) numbers. That may point out that the 14900K(F) CPUs may be general higher binned.
KitGuru says: It is no shock that the newer CPUs are typically higher binned than older ones. Nevertheless, given each batches of CPUs had been from across the identical time, it appears Intel may be selecting the higher silicon for his or her 14th Gen chips. This may be necessary in case you’re attempting to decide on between a Core i9-14900K(F) or a Core i9-13900KS.
