There have been reports coming from Taiwanese forums that Intel might be preparing a new mainstream desktop CPU with a higher core count under its new processor family expected to be known as Comet Lake.
In the forum, it was mentioned that a new 10 Core processor under the Comet Lake-S family was mentioned during a partner meeting. The processors under this family will still be manufactured using the 14nm process node. It recently featured in an updated DT/IOTG roadmap. These roadmaps are updated every quarter but a roadmap with this new family listed has not been seen in public yet.
Another thing that was mentioned in this rumor was that the CPU might be using a dual ring bus interconnect instead of a ring bus interconnect. It will be quite interesting if it turns out to be true because Intel has been quite accurate with its core to core latency on its mainstream chips for some time now. Most of Intel’s competitors rely more on interconnects due to cores allocated to dual dies, which affects the latency speeds. It would be intriguing to see how Intel deals with the core to core latency if it actually opts for dual ring bus interconnect.
Other than that, a 10 core processor with a single die would generate too much heat. Even Intel’s current 8 core, 16 thread chips are very hard to cool down. As there are no signs of the change in the manufacturing process, and with the core architecture being the same, a higher core count on this chip would only mean squeezing even more components in the same design and it, obviously, will lead to the generation of even more heat than the existing 8 core chip.
One way of taking care of the thermals is by adjusting the frequencies. In order to make this 10 core chip more thermally stable, Intel can just lower the all core frequency to a more appropriate limit. You’d still need a nice liquid cooling system to keep the temperatures in check on this 10 core CPU.
Talking about pricing, it can be expected to retail at above $500 US range as the 9900K currently retails for that much. If the supply issue of 14nm is not fixed by the time this CPU launches, the price can be expected to even reach $600 US.
For the performance statistics, this chip will surely be the most powerful mainstream chip Intel has even launched with great multi-core performance. Still, as is with all the leaks and rumors, nothing is confirmed yet, so take everything with a pinch of salt. Even the fact that we still don’t know if it is a ring bus or a dual ring bus design makes every claim about performance just a speculation. Anyway, we are pretty sure of one thing though, this chip is something to be really excited about and we’re eagerly looking forward to its launch in 2019. It’s also quite possible that by that time, AMD would have also come up with a new 7nm Zen 2 based mainstream chip with a higher core count.
