Intel Core Ultra 5 245K Linux Performance
Like we saw yesterday with the Core Ultra 9 285K, for raw web browser performance the new Arrow Lake processors were comparable to older Intel Core CPUs... But for power efficiency they are at the front of the race. Both the 245K and 285K were at the front when it came to the best performance-per-Watt in common web browser benchmarks.
With the WebAssembly (WASM) benchmarks the Arrow Lake processors were delivering better raw performance than the other web browser benchmarks. It's possible with the more demanding WASM workloads they are being tasked to P cores but potentially in the other light browser benchmarks ending up by the scheduler on E cores.
When it came to compiling the Linux kernel with a default x86_64 build, the Core Ultra 5 245K was doing so in about 74 seconds -- slightly faster than the Ryzen 9 7900 but behind the Ryzen 9 7900X. This also put it slightly faster than the Ryzen 7 9700X with a 105 Watt cTDP.
The Core Ultra 5 245K while compiling the kernel was consuming around 94 Watts on average, much lower than the 141~149 Watt average of the Core i5 13600K/14600K Raptor Lake processors.
With 14 physical cores the Core Ultra 5 245K was performing fairly well for a desktop processor in code compilation workloads. If doing a lot of code compilation tasks, you're best off basically buying as high of a core count CPU as you can afford.
