The Intel Core i7-5820K is the cheapest of three (5820K,5930K,5960X) new Haswell-E prosumer/enthusiast processors. The 5820K sports six physical cores and twelve threads which allow for enormous processing throughput. Unfortunately Intel have somewhat handicapped the 5820K by setting its base clock at just 3.3 GHz, 0.7GHz lower than the class leading 4790K. Comparing the 4790K and 5820K shows that the cheaper i7-4790K is significantly faster at both single and dual threaded workloads. The additional two cores found in the 5820K are not relevant to general computing and as such the 5820K probably makes a better server rather than consumer proposition. The Haswell-E X99 architecture also requires DDR4 RAM which is currently far more expensive than DDR3. Overall the 5820K is a very expensive option and probably best avoided by the vast majority of consumers.  [Sep '14 CPUPro]

The Intel Core i5-13500 offers an interesting mix of performance and value that will likely capture the attention of savvy PC builders providing its MSRP of $235 USD holds true. The 13500 features the same 6 P-cores and 8 E-cores as the i5-13600K, which currently retails for $320 USD. However, it has a lower boost clock frequency (4.8 GHz versus 5.1 GHz) and less cache (35.5 MB versus 44 MB) which translates to a 10% performance disadvantage against the 13600K. Nevertheless, paired with a B660 motherboard and inexpensive DDR4, the 20 thread i5-13500, is a very capable mid-range processor for both gaming and multi-threaded tasks. Compared to AMD’s similarly priced, hex-core Ryzen 5 7600 and 7600X, the 13500 offers better gaming and 50% faster multi-core performance which is particularly beneficial to workstation and professional users. Intel has completely priced AMD's 7000 series CPUs out of the rational market. Despite this, as long as Intel continues to sample and sponsor marketers that are mostly funded by AMD, they will struggle to win market share. [Jan '23 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
