Replacing the Intel Alder Lake-S 12th Gen Core family, the Intel Raptor Lake-S lineup will be part of the 13th Gen Core family and feature two brand new core architectures. These architectures will be featuring Raptor Cove as performance cores & an enhanced Gracemont core which will be serving as efficiency cores.


Intel Raptor Lake-S Desktop CPU Lineup & Configurations


According to previously leaked data, the lineup will consist of three segments that were leaked out in the recent power recommendations. These include the 'K' series enthusiast SKUs rated at 125W, 65W mainstream SKUs, and 35W low-power SKUs. Coming to the top-end variants, we will be getting up to 24 cores followed by 16 core, 10 core, 4 core, and 2 core variants.


It is estimated that for 13th Gen Raptor Lake CPUs, Intel is going to feature 2 MB L2 / 3 MB L3 cache per Raptor Cove core while each Gracemont Cluster will feature 4 MB L2 and 3 MB L3 cache. That's going to give us 36 MB L3 cache across all cores, 16 MB (2x8) for P-cores & 16 MB (4x4) for E-cores. Intel Raptor Lake & Alder Lake CPU Cache Configurations (Rumored):


  • Raptor Lake P-Core L3 - 3 MB (3 x 8 = 24MB)
  • Alder Lake P-Core L3 - 3 MB (3 x 8 = 24 MB)
  • Raptor Lake P-Core L2 - 2 MB (2 x 8 = 16 MB)
  • Alder Lake P-Core L2 - 1.25 MB (1.25 x 8 = 10 MB)
  • Raptor Lake E-Core L3 - 3 MB (3 x 4 = 12 MB)
  • Alder Lake E-Core L3 - 2 MB (2 x 2 = 4 MB)
  • Raptor Lake E-Core L2 - 4 MB (4 x 4 = 16 MB)
  • Alder Lake E-Core L2 - 3 MB (3 x 2 = 6 MB)
  • Raptor Lake Total Cache (L3+L2) = 68 MB
  • Alder Lake Total Cache (L3 + L2) = 44 MB
If this ends up being true, we are looking at a 55% increase to the total cache count for Intel's 13th Gen Raptor Lake CPUs. Now AMD will still retain the edge with its standard Non-V-Cache parts that are equipped with 64 MB of L3 cache and 96 MB on the V-Cache SKUs but this would mean that the blue team can recoup its lead quite significantly with the added cache and core count along with a higher clock speed that is expected from a further improved 10ESF (Intel 7) process node. The SKUs are detailed below:


  • Intel Core i9 K-Series (8 Golden + 16 Grace) = 24 Cores / 32 Threads / 68 MB?
  • Intel Core i7 K-Series (8 Golden + 8 Grace) = 16 Cores / 24 Threads / 54 MB?
  • Intel Core i5 K-Series (6 Golden + 8 Grace) = 14 Cores / 20 Threads / 44 MB?
  • Intel Core i5 S-Series (6 Golden + 4 Grace) = 14 Cores / 16 Threads / 37 MB?
  • Intel Core i3 S-Series (4 Golden + 0 Grace) = 4 Cores / 8 Threads / 20 MB?
  • Intel Pentium S-Series (2 Golden + 0 Grace) = 4 Cores / 4 Threads / 10 MB?
The enthusiast 125W Intel Raptor Lake-S Desktop SKUs will feature Core i9 models featuring up to 8 Raptor Cove cores and 16 Gracemont cores for a total of 24 cores and 32 threads. Intel's Core i7 lineup will consist of 16 core (8+8), Core i5 models will consist of 14 core (6+8) and 10 core (6+4) & finally, we have the Core i3 models which will feature 4 cores but without any efficiency cores. The lineup will also include Pentium SKUs which will feature just 2 Raptor Cove cores. All Core variants will feature a 32 EU (256 core) enhanced Xe integrated GPU. Certain Core i5 and Pentium variants will also come configured with 24 EU and 16 EU iGPUs.

Intel Raptor Lake-S Desktop CPU Platform Details

Other details include a larger L2 cache which will be branded as Intel's own 'Game Cache' for Core CPUs and clock speeds will feature a boost clock bump of 200 MHz so we can expect up to 5.5 GHz boost clocks considering Alder Lake-S Desktop CPUs will top out at 5.3 GHz.

The Intel Raptor Lake-S chips will also support faster DDR5 memory speeds of up to 5600 Mbps (6500 Mbps LPDDR5(X)) along with retaining support for DDR4 memory as reports suggest. It looks like there will be three main dies which will be configured into these SKUs starting with a top 'Large' die consisting of 8 Cove and 16 Atom cores, a 'Mid' die with 8 Core and 8 Atom cores, and lastly, a 'Small' die with 6 Cove cores and no Atom cores.
 
Intel Raptor Lake CPUs look very fast, and good for playing PC games in 4K video resolution at high quality video settings.

Indeed from the leak. Though I worry about the temps. Alder Lake runs hot hopefully the issue is fixed with Raptor Lake.
 
Read on Intel's latest roadmap from notebookcheck:

The first up on Intel's CPU roadmap is Raptor Lake, due in 2H 2022. Retaining the 7 nm process of Alder Lake, Raptor Lake will offer up to 24 cores and 32 threads. Still, Intel expects double-digit performance improvements with Raptor Lake, despite not embracing a die shrink.

By contrast, 2023 should bring the arrival of Meteor Lake, the first architecture to utilise the Intel 4 node. Purportedly, Meteor Lake could include iGPUs that compete with the performance offered by their dedicated counterparts. Subsequently, Intel will bring Arrow Lake to market, which should combine elements of Meteor Lake's architecture with Intel 20A manufacturing.

With Arrow Lake expected in 2024, Lunar Lake is not estimated to arrive until sometime in 2025. Apparently, Lunar Lake will be manufactured internally and externally, as will Arrow Lake. Unfortunately, Intel is yet to reveal further details about these architectures yet.
