A decent CPU, however, stuck inside the smaller chassis of the Alienware 15 R3 (2017) it continually thermal throttles. This makes the main positive aspect of this chip, being unlocked, pretty much useless as the temperatures will rise too much for overclocking to be useful. Even without overclocking this chip runs very hot.

Using it since it was lunched 2017. it was good CPU then, still good, never felt the need to upgrade even with the new super fast 13980hx. Using it with 64GB in MSI gt83 and no complains. I even sometimes underclock to save power.

 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
