The CPU we have is Intel Core i5-8265U and it’s pretty interesting how it fares against its Kaby Lake Refresh predecessors i5-8250U and i7-8550U.
The new Core i5-8265U is almost identical to i5-8250U – the sole difference is in the Turbo Boost frequency. While i5-8250U can reach 3.40 GHz when boosted, the new i5-8265U reaches 3.90 GHz. Both CPUs have a base frequency of 1.6 GHz.
|Cinebench 11 (Multi)||Cinebench 15 (Multi)||Adobe Photoshop (lower is better)|
|Intel Core i5-8250U||6.00 (+7%)||540 (+8%)||10.70 sec (+10%)|
|Intel Core i5-8265U||5.62||502||9.70 sec|
|Intel Core i7-8550U||6.5 (+16%)||590 (+18%)||9.70 sec (-)|
As you can see, 8250U has an advantage in 2 of 3 tests which means that the new CPUs are not ready for the market and have to go through more optimizations. However, the performance in Adobe Photoshop is pretty impressive and if we can make our conclusion based on it, we can expect around 10% more performance from i5-8265U (Whiskey Lake), compared to 8250U (Kaby Lake Refresh).
Anyway, we have to wait a bit to get our hands on more laptops with Whiskey Lake chips. Then we could be more precise in our comparisons.
