If you finish the bench and your temps are fine with no crashes, go into the bios and change the frequency to 41. If your temps are too high, then lower the voltage. If your system crashes at any time, dont worry, just go into the bios and up the voltage to 1.31. For daily use, below 80C is fine for the long term. For me, spikes above 80C are fine, but averages are what I look for. Run the benchmark in window mode and watch your temps in XTU. 5820k cinebench download#Download Intel XTU to watch your temps and run a Cinebench r15 benchmark. This will give you a 4ghz clockspeed at 1.3 volts. I would go into the bios and set your vcore to 1.3 and your frequency to 40. You have a decent cooler so you should be able to get a decent OC. It really just depends on your risk acceptance. Some people are willing to go to 1.45 volts and some people wont go above 1.3 volts. My personal rule of thumb is to keep voltage below 1.4 (preferably below 1.35) and average load temps below 80C. It is also harder to damage a CPU these days as they have built in save guards to protect from damage. Overclocking is really not some mythical science. Intel has been pretty stagnant on performance since your 5820 was released, so you are not missing out on too much. And when (in reality, if) the CPU-centric workload relies on single-threaded performance, Devil's Canyon's fast clock rate should not be overlooked.Your CPU is not a dinosaur just yet. 5820k cinebench software#At stock speeds, the performance difference depends on a software suite's preference between cores/cache and frequency. The underlying story from our CPU-heavy tests is that an overclocked Haswell-E 5820K is considerably faster than a frequency-boosted 4790K in multi-threaded workloads. That means you can add a third onto the conversion time of your game and holiday videos when using an overclocked 4790K, as opposed to the 5820K. Overclocking both chips extends the six-core Haswell-E part's lead to an impressive 32%. Two additional cores and 7MB more cache combine to overcome the 0.8GHz frequency deficit and give the stock-clocked 5820K an 11.5% performance lead over the reference 4790K. Handbrake‘s media conversion workload loves threads, speed, and cache, so it comes as no surprise to see Haswell-E chips leading the pack (excluding the stock-clocked 5820K). The 4790K is about seven-and-a-half percent faster than the 5820K when both are overclocked. Overclocking the chip to 4.5GHz does help it leapfrog the 4960X and 5960X flagships, but Devil's Canyon's speedy clock rate and high performance DDR3 keep it cemented to the top two positions. High clock speed and fast, low-latency memory keep the Devil's Canyon chip out in front for the single-threaded test.Ī low CPU clock speed and loose timings for its 2400MHz DDR4 hinder the 5820K's performance in Super Pi. The 5820K outperforms a 4790K by about 18% in the stock multi-threaded test – a lead that extends to 36% when both chips are overclocked. Overclocked to the same frequency as our 4960X, and the Haswell micro-architecture shows its underlying improvements with performance gains in the single- and multi-threaded tests. 5820k cinebench movie#We measured the average frame rate achieved for a task of converting a 4.36GB 720P H.264 movie (in the MKV container) to one in the MP4 container.Īt its 3.6GHz MCT speed, the twelve-thread 5820K performs almost identically to IVB-E's flagship in Cinebench. We used the 32M test in Super Pi to analyse single-threaded performance. The benchmark also shows noticeable scaling with clock frequency and cache size. We used the ‘CPU’ test built into Cinebench R15.Ĭinebench is effectively optimised to scale its workload across a CPU's threads.
