The new Intel Raptor Lake Refresh CPUs are on the best way for desktop fanatics. While 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 achieve 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. So far, Intel has launched six desktop CPUs, all of that are a part of the 125W Ok-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, equipped a sampling of 600 CPUs for the testing, which was run by a bunch of overclockers. As anticipated from a 600-sample take a look at, nobody evaluated particular person processors. However, some primary examinations could also be executed rapidly utilizing accessible instruments. The exams have been carried out on an Asus Z790 ROG Maximus Hero motherboard with BIOS 1402. People doing these exams file SP (Silicon Prediction) scores for P-Cores and E-Cores and voltage on the highest claimed frequency (for the 14900K, that will be 6.0GHz). The outcomes could be discovered within the desk under:
| 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 |
One of probably the most intriguing topics for this era of Core i9 CPUs is the distinction between the Core i9-14900K and the Core i9-13900KS, which have an identical configurations and clocks. The overclocking group tried to determine this by evaluating the batch of i9-14900K(F) that they had at hand with a batch of i9-13900KS chips manufactured in 2023. This assures that there’s little to no variation throughout exams.
According to the outcomes, the i9-13900KS wants 1493mV within the worst-case scenario and 1433mV within the best-case state of affairs. As a end result, 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 would point out that the 14900K(F) CPUs is perhaps general higher binned.
KitGuru says: It’s no shock that the newer CPUs are usually higher binned than older ones. However, given each batches of CPUs have been from across the similar time, it appears Intel is perhaps selecting the higher silicon for his or her 14th Gen chips. This is perhaps essential in case you’re making an attempt to decide on between a Core i9-14900K(F) or a Core i9-13900KS.
