Are Arrow Lake-S processors like fine wine? Do they improve with age? Phoronix has carried out a whole battery of tests on the CPUs, and the Core Ultra 9 285K has seen its performance rise on Linux, while its power consumption has been drastically reduced. In short, more performance, less power consumption – how perfect is that?
Arrow Lake-S: more performance, less power consumption!
In a nutshell, our colleague has carried out Arrow Lake-related tests based on the results of the Core Ultra 9 285K one year after its launch. What emerges is a processor with enhanced performance. After a full battery of tests, including various use cases such as code compilation, web, HPC, simulation, etc., etc., in none of the cases was there any regression in performance, a feat in itself. Better still, overall, performance was up by an average of 9%. Of course, depending on the use case, the percentage will be greater or lesser.
The other interesting point concerns the processor’s overall power consumption, which has fallen. In broad terms, the Core Ultra 9 285K used for these has seen its power consumption fall by around 15%. That’s real optimization, and a big step forward, since the performance increase isn’t simply achieved by overclocking the CPU – no, it’s clean.
Finally, it’s worth noting that early next year, somewhere in the first quarter, Intel will be launching refresh versions. We’re expecting higher frequencies and a few changes to the cores. Core Ultra 5 and 7 are expected to feature more E-Core, while native support for DDR5 at 7200 MT/s has been announced.
