![]() And in this benchmark, the Core i9-12900HX was thermally limited the entire time, never going above about 3.3GHz.Ĭinebench and Passmark are synthetic benchmarks - they measure theoretical performance, which doesn’t always translate into the real world. For that, I used the video encoding app Handbrake. The Core i9-12900HX stayed throttled throughout the test as it did in Cinebench, reaching as high as 98 degrees Celsius and hovering between 2.7GHz and 3.5GHz.īut once again, the 16-core monster showed its power, being 20% faster than the Core i9-12900HK inside the MSI GE76 Raider and 43% faster than the M1 Pro (though, admittedly inside the thermally-constrained MacBook Pro 14). Intel is laughing in the face of thermal throttling with the Core i9-12900HX. ![]() It may never reach the advertised 5GHz when all the cores are running, but it doesn’t matter when you’re focused on the CPU, the Core i9-12900HX decimates everything. The gains aren’t always as stark, though, and in some cases, thermal throttling laughs back. Taking the Core i9-12900HX out into the real world, the performance boost isn’t as drastic. ![]() In PugetBench for Premiere Pro, the Core i9-12900HX is a mere 4% faster in export performance than the Core i7-12700H inside the Lenovo Legion 5i Pro. It’s an advantage, but not much of one considering the Lenovo laptop is $2,400 while the GT77 Titan with the Core i9-12900HX is $5,000. You don’t need 16 cores for gaming, sure, but the thermal constraints the Core i9-12900HX imposes mean you can actually see lower performance. In the CPU-limited Assassin’s Creed Valhalla, for example, the Core i9-12900HX was 8% slower than the Core i9-12900HK inside the GE76 Raider at 1080p.
