Conclusion 
Average Bench 41.9%
Average Bench 98.8%

Beast processor during its time, when single core performance was king, but also software support, starting with Windows itself, was a major factor, it's crazy because all the benches at the time showed the e8500 beating the Phenom II 965 in gaming( the reason I was building a system) at the time, especially when it came to OC. Crazy what the benches are now, if you have Phenom II now with a mobo that works it may be useful (but they aren't very power efficient) but I burnt my mobo out overclocking so the point of what either processor could do 5 much less 10 years later is pretty moot. [Feb '21 qnytech1]

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]

 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.
