Intel 6 Core Coffee Lake i7 8700K & i5 8600K Specs Leaked – Launching Later This Year

Intel is reportedly planning to introduce 6 core Coffee Lake Core i7 and Core i5 processors for desktops later this year in addition to what will be the company’s very first 6 core mobile parts. Intel’s 8th generation Core series has been subject to a whirlwind of rumors surrounding the product’s availability. We’ve seen multiple report indicating that Intel has delayed these parts to early 2018 only later to learn that it’s been forced to push the launch forward again to combat the new formidable Ryzen products from AMD.

The original second half of 2017 release time-frame for Intel’s 8th generation core series products is still the official one, although earlier reports indicated that Intel could be forced to do yet another quad-core refresh based on Kaby Lake if Coffee Lake is indeed delayed yet again. The latest reports however indicate that the six core parts are back on track and you should be able to see them on shelves later this year. So what kind of products is Intel planning exactly? Let’s find out!

Intel Coffee Lake Core i7 8700K & i7 8700- Six Cores & Twelve Threads At 95W TDP

Let’s start with the flagship of the lineup, the Core i7 8700K. Although, I should point out that report from cpchardware tells us that Intel’s marketing department is in a state of “extreme nervousness” right now and these names could change as we approach the product launch. So make of that what you will.

The 8700K will reportedly feature six cores and twelve threads running at a core clock of 3.7GHz with a yet unknown Turbo frequency and is rated at 95W. This represents a notable clock speed bump up from Intel’s previous six core parts, including the recently launched Core i7 7800K which has a base clock of 3.5GHz and a TDP that’s higher by 45W.  3.7GHz is also funnily enough exactly 100MHz higher than AMD’s fastest six core Ryzen part the 1600X which has a base clock speed of 3.6GHz, but effectively runs at 3.7GHz with AMD’s XFR technology.

As the name implies, the i7 8700K will be unlocked for overclocking. The i7 8700 part, which is locked, will operate at a much more conservative clock speed of 3.2GHz and a yet unknown Turbo clock speed. The TDP for this part hasn’t been indicated in the report.

Intel Coffee Lake Core i5 8600K & i5 8400- Six Cores & Six Threads At 95W & 65W TDP

Moving on to the middle of the pack and the meat of the market, Intel’s i5 Coffee Lake chips will also feature six cores although with hyperthreading technology disabled, which means they’re limited to six threads rather than twelve like the i7 parts. These i5 parts also feature 9 MB of L3 cache instead of the standard 12 MB found in the core i7 CPUs.

The Core i5 8600K will operate at a base frequency of 3.6GHz and an unknown Turbo but is also rated at 95W like its bigger brother. And again, as the name implies this will be the unlocked part that overclockers will want to consider. Moving down the food chain we come to the Core i5 8400, just like the 8600K this is a six core part with hyperthreading disabled. Notably however, it runs at a significantly lower base clock speed of 2.8GHz and is rated at a lower TDP of 65W. This part will likely compete with AMD’s 65W six core Ryzen 5 1600 part.

Intel Coffee Lake Mobile CPUs

Lastly we come to the mobile chips. Intel will be introducing mobility processors with six cores for the very first time. These parts will reportedly run at around 2.0GHz, and will be rated at 45W. To complement the six core Coffee Lakes Intel will again release its standard market staple quad-core Coffee Lake-U parts with GT3e graphics. These will will feature the company’s high-end graphics solution with embedded DRAM and will be rated at a more frugal 28W. At this low of a TDP Intel only had dual core parts in the past, which indicates that Coffee Lake will be notably more power efficient than previous generation parts.
