From ExtremeTech: Intel’s latest Core i9-7980XE is a monster CPU and the fastest core you can buy in the consumer space today (for an extremely specific and well-heeled definition of ‘consumer,’ anyway). As with all high core count CPUs, however, Intel had to compromise on clock speeds. The all-core clock on a Core i9-7980XE drops to 3.4GHz under full load, to keep power consumption at a manageable level. Of course, if you’re overclocking with liquid nitrogen, you can ignore such minor inconveniences as TDP.
Overclocker Der8auer, whose work we have covered on several occasions, managed to boot the core at 6.1GHz, though he had to drop back to an all-core frequency of 5.6GHz. Asus provided the motherboard, a ROG Rampage VI Apex. That’s not quite the absolute benchmark-stable record that’s been hit, however — TechRadar reports another overclocker, Elmor, pushed the chip a bit harder and hit a CB15 score of 5,723.
While these speeds are tremendous–Der8auer’s Cinebench score of 5,635 is ~1.7x faster than what we logged in our own review–the reported power consumption of the system was over 1kW. Keep in mind, that’s in a test like Cinebench, where the impact of the GPU is going to be limited to a bit more than idle power.
