The Intel's specially binned i9-9900K, featuring 5GHz all core boost and base clock of 4GHz. This CPU is one of the most powerful Intel CPU in term of day-to-day and gaming performance but with TDP of 127W, bulky air cooler or 240mm AIO is recommended to make sure the CPU doesn't overheat, and open loop liquid cooling if you want to OC. [Jun '20 ColdSpy]

The FX-8370E is an energy efficient Vishera eight core desktop processor based on AMD’s Piledriver architecture. It was launched in September 2014 and is the energy efficient version of the FX-8370 boasting a lower TDP of 95 Watts versus 125 Watts on the FX-8370. Comparing the 8370E and 8370 shows that the lower TDP comes at a cost: the 8370E scores a relatively lacklustre effective speed of 73 compared to the non-E version which scores 83. The lower score is consistent with the relative clock speeds: 3.3 GHz on the 8370E versus 4.0 GHz on the 8370. Priced the same as the 8370, there is a direct choice between being green or speedy. Or, if you don’t really need the above average multi-threaded performance that the 8370E offers, then you may be better off with the superb single-threaded performance from any number of Intel’s offerings. [Dec '14 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
