Leak Confirms Increased LXNUMX Cache on Future Intel Processors

The SiSoftware Benchmark Database found a record of testing a server or workstation built on two mysterious six-core Intel processors. These processors are interesting primarily because they have a very unusual amount of second-level cache - 1,25 MB per core.

That's five times that of the 256KB L2 cache found on desktop Coffee Lake Refresh processors, and two and a half times that of the latest Ice Lake-U chips, which have 512KB per core. It's also 25% more than current Core-X HEDT processors or Xeon Scalable server processors, which have 1 MB of LXNUMX cache per core.

Therefore, the conclusion suggests itself that this processor uses one of the new Intel architectures. It can be 10nm Ice Lake or Tiger Lake, or 14nm Rocket Lake. Not much is currently known about the last two architectures, but one of the recent leaks about Tiger Lake just indicated that it has 1,25 MB of LXNUMX cache per core.

At the same time, another leak indicated that only mobile processors with no more than four cores would be presented in the Tiger Lake family. In turn, Rocket Lake chips will offer up to eight cores. In addition, the six-core chips tested in SiSoftware have less LXNUMX cache than the previously leaked Tiger Lake.

And here it can already be assumed that a smaller L3 cache may be the result of a less dense placement of transistors, that is, a “larger” technical process. It cannot be ruled out that here we are witnessing a transfer of architecture from a “thinner” 10nm process technology to the good old 14nm. Just recently сообщалосьthat Rocket Lake will use the new architecture, but on the old process technology.

There is another option: everything described in the previous two paragraphs will not come true, and we have a system on two 10nm Ice Lake-SP server processors. They may well have the same cores as mobile Ice Lake-U, but there will be more LXNUMX cache per core. For Intel, this practice is no longer a novelty.

Overall, it is difficult to draw any specific conclusions based on this result. As you can see, the possibilities are many, but the evidence is small. The only thing you can be sure of is that these six-core processors are not derived from Skylake.
