Intel Core Ultra 9 285K "Arrow Lake" Delivers Strong Linux Performance
First up was the Speedometer 3.0 benchmark within Mozilla Firefox where the Core Ultra 9 285K performance was underwhelming from the raw performance... But when looking at the performance-per-Watt, it inched ahead to deliver the best power efficiency of the tested Intel Core and AMD Ryzen desktop processors.
It was the same way with the Jetstream 2.0 benchmark where the raw performance was slightly behind Raptor Lake CPUs but then on a performance-per-Watt basis came out in front.
Ditto for Jetstream 2.0 within Google Chrome as well.
Within the WebAssembly (WASM) browser benchmarks is where the Core Ultra 9 285K came out ahead not only of the prior Raptor Lake (Refresh) CPUs but also the AMD Ryzen competition.
When moving onto more demanding test cases like code compilation, the Core Ultra 9 285K performance became much more interesting... Here for a default Linux x86_64 kernel build the Core Ultra 9 285K with its 24 cores was tied with the Ryzen 9 9950X 16-core / 32-thread processor.
The Core Ultra 9 285K on average was consuming around 155~157 Watts, similar to the Ryzen 9 9950X during this multi-job code compilation work, but with the Arrow Lake CPU topping out at 235 Watts compared to the Ryzen 9 9950X at 200 Watts.
