Intel’s new Raptor Lake Refresh CPUs have been beneath scrutiny in a brand new report which evaluated a bunch of silicon from the 14th-gen vary.
This comes from Igor’s Lab – a German web site which has beforehand performed related checks – and concerned some 600 of Intel’s processors, each 14th-gen and Thirteenth-gen for comparability. All these chips have been break up up amongst 5 intrepid overclockers for testing (a kind of being Igor).
Given the huge variety of CPUs being lined, the testing employed was essentially restricted, with the processors positioned in an Asus Maximus Z790 Hero motherboard, and Silicon Prediction (SP) values recorded (indicating the standard of the chip primarily).
Moreover, the voltage drawn was measured when on the most rated Turbo clock pace (with a decrease voltage which means the chip is best high quality – as there’s extra headroom to crank up the voltage for an even bigger overclock).
There’s a mountain of outcomes to wade by way of, as you possibly can think about, so we’ll select some temporary highlights.
The general conclusion is that Raptor Lake Refresh processors are higher binned (of a better silicon high quality) in comparison with their predecessors, Raptor Lake chips, however you then’d count on that basically (given generational course of and manufacturing refinements).
For instance, most voltages, the 14900K wanted as little as 1398mV in 4 circumstances to hit full Turbo, and the bottom the 13900KS managed was 1433mV (25 of the 14900K CPUS have been beneath that worth, in reality). This exhibits that with specs in any other case similar, the 14900K is a superior piece of silicon general (although there might be variances, and it’s essential to notice the 13900KS pattern dimension is far smaller right here, which may have an effect).
As talked about, with extra headroom to permit voltage to be pushed usually, Raptor Lake Refresh is giving overclockers extra scope for juicing up clock speeds that little bit extra.
One other attention-grabbing level is that the report compares the usual 14900K in opposition to the 14900KF model (which is similar, however lacks built-in graphics). Was there any marked distinction within the two spins on the flagship?
The 14900KF chips had an expansion of SP values starting from 90 to 104, whereas the 14900K was between 92 and 112, indicating the next high quality for the latter.
Evaluation: No alarms and no surprises…
these final SP scores, the 14900K seems to be a greater proposition, however we have now to keep in mind that even a pattern of 600 processors hardly tells a definitive story, whether or not that’s pertaining to particular person head-to-head CPU performances, or the general image.
That stated, as famous it’s not shocking to see Raptor Lake Refresh is best binned than the previous-gen Raptor Lake chips, and certainly that the brand new CPUs overclock higher. If you happen to recall, it was even the case that lengthy earlier than the 14th-gen processors emerged there have been leaks indicating that Raptor Lake Refresh was going to be a strong step ahead on the overclocking entrance.
So actually, there aren’t any massive surprises right here, however the results of that 14900K versus 14900KF battle is attention-grabbing to see.
Nonetheless, any Raptor Lake Refresh shopping for determination might be based mostly on how a lot of an improve it’ll be from what you’re at the moment operating, and the efficiency enhancements for the 14900K aren’t spectacular gen-on-gen as we identified in our full evaluation.
If you happen to’re desiring to overclock, although, there’s positively a bit extra mileage on this new technology of Intel silicon, and the report actually makes this clear (simply be sure to get your self a top-notch CPU cooler).
