Well till now we were using 8-core processors, but Intel announced its first 10-core desktop CPU, the Core i7-6950X Extreme Edition at Computex. This beast will run at 3GHz and use 25MB cache and feature Intel's new Turbo Boost 3.0 technology. Just when we thought it is so amazing it gives a blow to the pocket as the 10-core i7 Extreme Edition will be costing $1,723.
Intel claims it's twice as fast as the quad-core i7 6700K when it comes to 3D rendering, and 35 percent faster than the last-gen Core i7-5960X. When it comes to editing 4K video, it's 65 percent faster than that same quad-core chip and 25 percent faster than the previous i7. On the gaming front, it's 25 percent faster than the 5960X when it comes to gaming in 4K while encoding and broadcasting a 1080p Twitch stream.Basically, if you're dealing with massive amounts of content on a daily basis, it could be the ideal CPU for you.(source - engadget )
The new Extreme Edition of i7 processors will also be available in an 8-core version (the i7-6900K for $1,089) and 6-core variants (the $617 i7-6850K and the $434 i7-6800K). Naturally, they're completely unlocked, so you can overclock them to your heart's content. All of the new chips also support DDR4-2400 RAM, a slight bump in speeds from the previous-gen processors.
