Unreleased Intel 6 core CPU From the SiSoftware Database Credits Earlier Rumors Regarding Backporting Of CPUs

SiSoftware Sandra database has been one of the sources of information regarding consumer hardware. Now, an unreleased CPU from Intel has shown up on the database with a rather odd architectural design that could lead to something new from Intel. The 6C and 12T chip may seem regular, but cache quotes paint a different picture altogether.

Intel has released many multithreaded six-core processors as part of their core series or Xeon series though the 9th gen Coffee Lake refresh did not have any hexacore processor. The alleged processor in the database could be the unreleased 9th gen processor.

The processor has a clock speed of 2.99GHz, which is not on par with other 14nm processors since the process is very mature. It is standard assuming the processor is actually an engineering sample. A backported processor could support higher clock speeds even at the incubation level, but the processor seems to be at an initial level of production.

Coming to the more exciting bit of the reveal, the processor has a unique cache system. According to Wccftech, the processor has 9MB of L3 cache and 7.5MB (1.25MB per core) of L2 cache. 1.25MB of L2 cache per core is not something that Intel has been able to achieve yet. The 9th gen processors have 256 KB of L2 cache, the 10nm Ice Lake CPUs possess 512KB, and the Core-X series features 1MB of L2 cache.

The only architecture that features 1.25MB of L2 cache is the upcoming Tiger Lake lineup. However, the L3 cache becomes an anomaly since it only features 1.5MB of L3 cache per core, and the 9th gen processors have 2MB of L3 cache. The Tiger Lake processors will feature an even bigger L3 cache window.

All in all, if we take the whole clock speed and cache quotes into account, we could only say that the alleged processor is one of the backported processors (from Tiger Lake to Rocket Lake). Since backporting requires shifting of nodes, we may see irregular cache designs and higher clock speeds in the upcoming processors. The processor in hand could be the early pre-production unit of the backported processors. Wccftech reports that it could be the unreleased part of the Xeon processors to be featured in the Ice Lake(E) family next year.
