Introducing the Core i7-5820K! This Desktop processor is a marvel in Intel's high-end range. Debuted in 2014, it's packed with 6 cores and 12 threads. It operates at a base clock speed of 3.3GHz, can ramp up to 3.6GHz, and has a power consumption of 140W, ready to supercharge your gaming system. The Core i7-5820K is built on the Haswell-E 22nm platform and belongs to the esteemed Core i7 series.

And guess what? The Core i7-5820K is the ultimate successor to Intel's previous-gen gaming champion, the Core i7-4820K. The Core i7-4820K was based on the legendary Ivy Bridge E and 22nm process, and it made its grand entrance into the gaming scene back in 2013. But now, it's time for the Core i7-5820K to take the throne and conquer the gaming world!

This CPU packs 6 cores and 12 threads, the first time this many come in a mainstream package! Plus, it costs about the same as the FX-9590, which only has 8 cores and 8 threads. Talk about a total noob!

Can the Intel Core i7-5820K finally dethrone the king of mainstream CPUs, the FX-9590? It's a maybe. The Core i7-5820K doesn't quite reach the same single-core performance as its rival, but more games are starting to use all those threads, so who cares!

The Intel Core i7-5820K is an absolute monster, just like its 6 cores, 12 threads, and hefty price tag suggest. This is the top dog of mainstream processors, the king you've been waiting for. Games, video editing, 3D work – the Core i7-5820K handles it all with ease. Bow down to the king!

The Core i7-5820K sits just below the mighty Core i7-5930K with its fancy 22nm compute die and beefy 6 cores and 12 threads. While the Core i7-5930K might seem like the obvious winner, Intel has done some magic to keep the Core i7-5820K's single compute die design efficient. Plus, the higher TDP allows for more aggressive boost clocks. This means the Core i7-5820K could actually compete with the Core i7-5930K in some games – who knew?

The Intel Core i7-5820K launched on Sep 2014 for $410, which is pretty much the same price as the last-generation Core i7-4820K. At least there's no crazy price hike this generation!

The high number of threads (over 7!) in the Intel Core i7-5820K makes it a monster for tasks that use all the cores at once (multi-threaded workloads), especially for the price. If you edit a lot of videos or work with giant spreadsheets, the Core i7-5820K will give you a noticeable performance boost.

The Intel has disabled the graphics on the Core i7-5820K, so it doesn't have any integrated graphics - just like the FX-9590. This makes the Core i7-5820K cheaper than the Core i7-4820K, even though the price difference might not be obvious at first glance. You can find the Core i7-5820K for $410 while the Core i7-4820K is still $399. That's a whopping -3% discount for the newer CPU! It's also cheaper than the FX-9590 which costs $495.92.

Today's review is on the Intel Core i7-5820K, a 6-core desktop processor launched in Sep 2014. Intel sells the Core i7-5820K without integrated graphics, making it perfect for systems with a dedicated graphics card. It costs $410 and is a great option for those who already have a GPU.

The Core i7-5820K is a great choice for both gaming and content creation, thanks to its high performance (0.94%) and at least 12 threads. Live streaming, eSports, and uploading gameplay videos are becoming increasingly popular, and this CPU can handle it all.

Building on the success of mainstream Core i7 CPUs, Intel is now attacking the high-end market with the Core i7-5820K processors, available since Sep 2014.
