In­tel’s Whiskey Lake note­book chips will of­fer big turbo boosts to get you to up­grade

If the leaked in­for­ma­tion is cor­rect, there will be just the one key dif­fer­ence be­tween to­day’s Kaby Lake-r chips and In­tel’s Whiskey Lake.

PCWorld (USA) - - News - BY MARK HACHMAN

While moth­er­board com­pa­nies con­tinue to outdo them­selves re­leas­ing data on In­tel’s up­com­ing 9000-series pro­ces­sors, HP has ac­ci­den­tally dis­closed de­tails regarding another of In­tel’s up­com­ing chips: its “Whiskey Lake” note­book pro­ces­sors.

As dis­closed by Anandtech ( go.pc­world. com/15ww), the Whiskey Lake-u pro­ces­sors aren’t that dif­fer­ent from the ex­ist­ing Kaby Lake-r chips that they’ll re­place. In fact, the base clock speeds for the three chips outed by HP are es­sen­tially iden­ti­cal with the ex­ist­ing Kaby Lake-r chips. What In­tel has done, how­ever, is of­fer sig­nif­i­cantly higher turbo speeds as a way of dif­fer­en­ti­at­ing the two fam­i­lies.

It’s worth not­ing that “dif­fer­en­ti­a­tion” con­tin­ues to be an is­sue, as far as prod­uct num­bers go. The three new Whiskey Lake-u chips—the 2.1GHZ Core i3-8145u, the 1.6GHZ Core i5-8265u, and the 1.8GHZ

Core i7-8565u—use sim­i­lar prod­uct num­bers to the 2.2GHZ Core i3-8130u, the 1.6GHZ Core i5-8250u, and the 1.8GHZ Core i7-8550u Kaby Lake-r chips they re­place. Cache sizes re­main the same, ac­cord­ing to the HP list­ing, Anandtech re­ports. Both the Core i5 and Core i7 have four cores, while the i3 has two.

Here’s the dif­fer­ence: the turbo speeds, as in­dicted be­low.

Core i7-8565u (Whiskey Lake) 1.8GHZ base, 4.6GHZ turbo

Core i7-8550u (Kaby Lake-r) 1.8GHZ base, 4GHZ turbo

Core i5-8265u (Whiskey Lake) 1.6GHZ base, 4.1GHZ turbo

Core i5-8250u (Kaby Lake-r) 1.6GHZ base, 3.4GHZ turbo

Core i3-8145u (Whiskey Lake) 2.1GHZ, base, 3.9GHZ turbo

Core i3-8130u (Kaby Lake-r) 2.2GHZ base, 3.4GHZ turbo

In­tel doesn’t com­ment on unan­nounced prod­ucts. And nat­u­rally, the of­fend­ing HP spec sheet, gov­ern­ing its Pavil­ion x360 con­vert­ible, has been re­moved. (Note that HP is listed as a launch part­ner as part of In­tel’s Com­pu­tex an­nounce­ment of Whiskey Lake, above.) In­tel has con­firmed ( go.pc­world. com/sphd) that the Whiskey Lake and Am­ber Lake ar­chi­tec­tures will ship by the hol­i­day sea­son, how­ever.

Both the cur­rent Kaby Lake-r chips and the up­com­ing Whiskey Lake chips are

U-series chips, which typ­i­cally con­sume about 15 watts. Am­ber Lake is a Y-series chip, aimed at ul­tra-low-power ul­tra­books, usu­ally in the 4.5-watt range.

What this means for you: As noted by Anandtech, the ad­di­tion of turbo boost will cer­tainly help in cases where a chip en­coun­ters a short-term, “spiky” load, where turbo boost can kick in and speed up op­er­a­tions for a short time. But un­der pro­longed loads, you may be bet­ter off stick­ing with a Kaby Lake-r chip, as far as pro­cess­ing power is con­cerned.
