XPS 13 9380 | Core i5-8550U
The XPS 13 9380 | Core i5-8550U price in Kenya is 147,500 shillings. It comes with 8192 MB, LPDDR3-2133 Dual Channel (8GB soldered, not upgradeable) Memory, and 256 GB, NVMe storage.
As always, the interesting question is whether the cooling solution can maintain the performance when the loan period is longer. Slim subnotebooks often struggle with this task, and the initial high performance (Turbo Boost) often drops by 15-30%, which results in lower benchmark scores compared to the initial run. So what about the 2019 XPS 13? The processor starts with 3.7 GHz in the Cinebench R15 Multithread, but it drops to 3.3-3.4 GHz after a couple of seconds. This level can be maintained for the first four minutes because the chip warms up to 99 °C and occasionally has to reduce the clocks down to 2.5 GHz. The CPU cools down to 80 °C in these periods, before it increases the clock and warms up to almost 100 °C again – source.
The XPS 13 9380 | Core i5-8550U quad-core processor is a ULV chip (TDP 15W) based on Intel’s Whiskey Lake architecture. The processor runs at a base frequency of 1.6 GHz, but it can reach up to 3.7 GHz (all four cores), 3.8 GHz (two cores), or 3.9 GHz (one core) via Turbo Boost. The Whiskey Lake architecture of the Core i5-8265U processor does not differ much from the previous Kaby Lake architecture used for the 2018 XPS 13. The per-MHz performance is identical, but the improved manufacturing process of Whiskey Lake allows higher clock rates. In theory, the higher frequency of the 8265U should be faster than the previous Core i5-8250U processor in our CPU benchmarks. However, this is not the case: The Cinebench R15 Multitest shows both CPUs are similarly fast, and the new chip is only 3% ahead in the Single test. This is the case for one benchmark run, but the Whiskey Lake chip is ahead under sustained workloads.
