First listings of Intel’s upcoming Coffee Lake 6 core and 4 core processors have been sighted. The new processors were spotted in Sisoftware database and are part of the desktop and embedded platforms.
Intel Coffee Lake Desktop 6 Core and Embedded 4 Core Processors Detailed
Intel is pushing ahead with the launch of their next generation processor families against its competitor AMD’s Ryzen Processors and we are finally starting to get new information on Intel’s high-end desktop CPU platform. The new processor platforms are scheduled to launch in mid of 2017.
First, up will be the high-end Skylake X and Kaby Lake X CPU families which will range from 4, 6, 8, 10 and 12 core SKUs. The more mainstream desktop oriented family will arrive after that in the form of Coffee Lake S. This line-up will feature Intel’s first 6 core mainstream processor.
Intel Coffee Lake chips were set to launch on January 18′ at CES but recent AMD launches push the company to shake up their roadmap. The recent reports also suggest that the Coffee Lake chips can launch early in August at GamesCom 2017.
Newer chips will launch alongside the Z370 chipset based motherboards and would be followed by H370 and B360/H310 chipsets at the end of 2017 or may be in early 2018.
Intel Coffee Lake S 6 Core Part Could be a Core i5 Processors – Features No Hyper Threading, Up To 3.50 GHz Clock Speed on Engineering Sample
The first processor most users would be interested to know about is the Coffee Lake 6 core part. It will be Intel’s first 6 core, mainstream and consumer-oriented processor. This will carries some very interesting specifications and first of all, it is a 6 core part of the processor that feature no hyper-threading.
It comes with 3.5G base clock and no turbo boost speed is mentioned. My guess is what we are looking at an engineering sample and final chip will ship with higher clock speeds. This chip features 1.5MB of L2 cache (6*256 GB) and 9MB L3 Cache.
How do you know its Coffee Lake Processor?
The chip we are looking at was running on Kaby Lake-S client platform. Kaby Lake-S is mainstream line which currently supports Skylake and Kaby Lake consumer processors and This is not the HEDT line which should have the Kaby Lake-X codename. The high-end 6 core Broadwell-E parts features upto 20MB L3 cache wherease processor we are talking about has less than half of it.
The cache also tells us a lot about this processor. We know from previous Intel architectures that each core has 2 MB of L3 cache and the entire cache is shared across all cores.
A 4 core, 8 thread Kaby Lake chip featured 8 MB of L3 cache. So this chip should have theoretically featured 12 MB of L3 cache that would be shared across all cores.
But since this is a disabled chip since it doesn’t feature hyper-thread, the conclusion is that we are looking at a Core i5 series 6 core chip. Intel isn’t making big changes with Coffee Lake and since the design heirarchy is mostly similar to Kaby Lake, a Core i5 chip with disabled design should feature 9 MB of L3 cache.
A disable Kaby Lake Core i5-7600K chip also featured less cache of 6 MB compared to 8 MB L3 cache on the Core i7-7700K chip.
