In keeping with a brand new leak, Intel Raptor Lake processors could also be getting a a lot bigger cache than their current-gen Alder Lake predecessors. The rise in cache dimension, which is rumored to be as much as 68MB, could end in an enormous efficiency increase.
Intel hasn’t stated a lot in regards to the upcoming processors, however that doesn’t cease rumors from surfacing. Following a cryptic tweet and several other extra in-depth responses, we now know extra in regards to the rumored Intel Raptor Lake improve.
68M cache is attention-grabbing.😄
— Raichu (@OneRaichu) January 14, 2022
The present leak began with OneRaichu on Twitter, who tweeted a imprecise message: “68M cache is attention-grabbing.” OneRaichu then clarified that the 68MB cache in query is alleged to belong to an Intel Raptor Lake processor, indicating a large enhance in cache dimension. This is able to translate to an enchancment in general CPU efficiency.
Though the unique leaker didn’t observe up with extra info, one other consumer (Olrak29_) chimed in with a diagram that higher explains the alleged core configuration of Raptor Lake CPUs. With a rumored mixed cache (L2+L3) of 68MB, the CPU can have a considerably complicated cache distribution.
In keeping with the diagram, every Raptor Core Golden Cove (efficiency) core has 2MB of L2 cache and 3MB of L3 cache. The effectivity Gracemont core clusters, every consisting of 4 E-cores, have 4MB of L2 cache and 3MB of L3 cache. As Intel Raptor Lake CPUs could have as much as eight efficiency cores and 4 effectivity core clusters, this provides as much as a most of 68MB. In a reply to the diagram, one other consumer shared the mathematical operation required to attain that consequence: 2*8+4*4+3*12.

So long as the rumors are correct, we’re a large enhance in cache dimension for Raptor Lake CPUs. In comparison with Alder Lake, we may even see Intel’s Thirteenth-gen processors with an as much as 60% bigger L2 cache within the Golden Cove cores and a doubled L2 cache within the Gracemont core clusters. Evidently the L3 cache per object could stay unchanged, however the two further Gracemont core clusters will enhance their dimension to 36MB.
Locuza on Twitter shared an image that exhibits the structure of Intel Alder Lake-S processors, and it serves as an excellent comparability to the rumored Raptor Lake. In keeping with the picture, Alder Lake processors, such because the Core i9-12900K, include 1.25MB of L2 cache for every P-core, and 2MB of L2 cache for each 4 E-cores. Each core part consisting of a Golden Cove core and a Gracemont core cluster additionally has 3MB of L3 cache, which provides as much as 14MB of L2 and 30MB of L3. This suggests that we’re certainly an enormous improve within the subsequent technology of Intel’s best CPUs.
Now we have already seen what a rise in cache dimension can do for a processor’s efficiency. When AMD upgraded the L3 cache upon switching from Zen+ to Zen 2, the gaming increase was plain. We could also be the same soar going from Intel Alder Lake to Raptor Lake.
The discharge of Intel Raptor Lake will mark the start of Intel’s Thirteenth technology of processors. The producer is protecting fairly hush a few doable launch date, however rumors level to a launch as early as this yr. With AMD quickly releasing Zen 4, it could make sense for Intel to attempt to keep forward of the curve.
