20 dollars for nothing go buy i3 8100 [Jul '18 Camel]

MORE DETAILS

The Intel 5960X sports eight cores and sixteen threads. That's two more cores than we have ever seen on a consumer processor before and as such this $1,000 processor offers record breaking multi-threaded CPU horsepower. Unfortunately the 5960X is clocked at just 3 GHz base and 3.5 GHz turbo which, for single and dual-core workloads, renders it around 15% slower than a $69 G3258 on stock clocks! The 5960X is only compatible with Intel's new X99 chipset which requires new DDR4 RAM and is currently far more expensive, with little consumer benefit, than DDR3. All in all the i7-5960X processor is largely irrelevant for consumers as it's far far too expensive. [Sep '14 CPUPro]

 Frequently Asked Questions

 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.
