Conclusion 
Average Bench 58.6%
Average Bench 76.8%

The Intel Core i7-4700MQ is a high end mobile Haswell (2013) CPU. Despite sporting base and turbo clock speeds of 2.4/3.4 GHz, the 4700MQ has a maximum TDP of just 47 Watts. Although the 4700MQ is a quad core processor, hyperthreading technology allows the operation of eight virtual cores which enable the 4700MQ to deal with multi-core workloads with ease. The overall effective speed rating for the 4700MQ is 85.5 which is just 12% slower than the average of the current 9 group leaders. Since the group leaders include both desktop and server models this is a particularly impressive score for mobile processor with a TDP of just 47 Watts - it's almost as good as a reasonable desktop. [Oct '14 CPUPro]

MORE DETAILS

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]

 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.
