![]() ![]() This is another great result for Kaby Lake-R. Single-threaded performance doesn't quite match what the quad-core 7700HQ provides, but multi-threaded performance is on par. Sin embargo, cuando someto la CPU a una prueba de estrs, la frecuencia salta a 2,4 GHz durante 2040 segundos y luego cae a 1,40 GHz durante el resto de la prueba. Single-threaded performance is impressive as well, jumping up 30 percent assisted by additional memory bandwidth and more cache. Tengo un nuevo porttil HP Elitebook 850 G5 con Intel Core i7-8550U que tiene TurboBoost hasta 4,00GHz y frecuencia base 1,80GHz. Here, the 8550U crushes the 7500U to the tune of 128 percent, again due to the addition of two cores and the extra clock speed provided. ![]() ![]() Running longer scripts will definitely benefit from this shorter compute time.Ĭompression is another extremely impressive workload for Kaby Lake-R, especially when multi-threaded. The i7-8550U once again pushes into i7-7700HQ territory, shaving 30 percent off the simulation time produced by the i7-7500U. It's a similar story in MATLAB, which will make engineers happy. It'll be interesting to see what Intel's H-series Kaby Lake-R (or Coffee Lake) parts bring to the table this year to counter getting beaten by Intel's own lower-TDP SKUs. The 8550U even outperforms the i7-7700HQ, and that's for the same reason: the boost frequency of the Kaby Lake-R 15W part is higher by 200 MHz. This is down the short duration of the Excel Monte Carlo workload it allows the i7-8550U to ramp all four cores up to the maximum turbo frequency of 3.7 GHz, which exceeds the 7500U's dual-core turbo speed of 3.5 GHz. The i7-8550U absolutely dominates this test, more than doubling the time the i7-7500U puts up. If you need to do some serious number crunching in Excel, Kaby Lake-R could be exactly what you are after. ![]()
