Intel’s new Raptor Lake Refresh CPUs had been beneath scrutiny in a brand new document which evaluated a number of silicon from the 14th-gen vary.
This comes from Igor’s Lab – a German website online which has in the past performed equivalent assessments – and concerned some 600 of Intel’s processors, each 14th-gen and Thirteenth-gen for comparability. These kinds of chips have been break up up amongst 5 intrepid overclockers for checking out (a type of being Igor).
Given the huge choice of CPUs being lined, the checking out hired was once 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 necessarily).
Moreover, the voltage drawn was once measured when on the most rated Turbo clock velocity (with a decrease voltage which means the chip is best high quality – as there’s extra headroom to crank up the voltage for a larger overclock).
There’s a mountain of effects to plow through, as you’ll be able to believe, so we’ll pick some transient highlights.
The full conclusion is that Raptor Lake Refresh processors are higher binned (of a better silicon high quality) in comparison to their predecessors, Raptor Lake chips, however you then’d be expecting that truly (given generational procedure and production refinements).
For instance, having a look at most voltages, the 14900K wanted as little as 1398mV in 4 circumstances to hit complete Turbo, and the bottom the 13900KS controlled was once 1433mV (25 of the 14900K CPUS have been under that worth, in truth). This presentations that with specifications in a different way equivalent, the 14900K is a awesome piece of silicon general (despite the fact that there might be variances, and it’s necessary to notice the 13900KS pattern dimension is far smaller right here, which will have an affect).
As discussed, with extra headroom to permit voltage to be driven generally, Raptor Lake Refresh is giving overclockers extra scope for juicing up clock speeds that little bit extra.
Any other fascinating level is that the document compares the usual 14900K in opposition to the 14900KF model (which is identical, however lacks built-in graphics). Used to be there any marked distinction within the two spins at the flagship?
The 14900KF chips had a range of SP values starting from 90 to 104, while the 14900K was once between 92 and 112, indicating the next high quality for the latter.
Research: No alarms and no surprises…
Having a look at the ones ultimate SP rankings, the 14900K appears to be like a greater proposition, however we need to needless to say even a pattern of 600 processors rarely tells a definitive tale, whether or not that’s relating particular person head-to-head CPU performances, or the whole image.
That mentioned, as famous it’s now not sudden to peer Raptor Lake Refresh is best binned than the previous-gen Raptor Lake chips, and certainly that the brand new CPUs overclock higher. Should you recall, it was once even the case that lengthy earlier than the 14th-gen processors emerged there have been leaks indicating that Raptor Lake Refresh was once going to be a cast step ahead at the overclocking entrance.
So truly, there aren’t any large surprises right here, however the results of that 14900K as opposed to 14900KF combat is fascinating to peer.
Nonetheless, any Raptor Lake Refresh purchasing resolution might be according to how a lot of an improve it’ll be from what you’re these days operating, and the efficiency enhancements for the 14900K aren’t spectacular gen-on-gen as we identified in our complete evaluation.
Should you’re aspiring to overclock, despite the fact that, there may be no doubt a bit of extra mileage on this new era of Intel silicon, and the document without a doubt makes this transparent (simply you’ll want to get your self a top-notch CPU cooler).
