Intel Arrow Lake-S Desktop CPUs Come In 24 Core “Core Ultra 9”, 20 Core “Core Ultra 7” & Up To 14 Core “Core Ultra 5” Variants

The CPU configurations of Intel's Arrow Lake-S "Core Ultra" Desktop CPUs have been revealed, offering up to 8 P-Cores & 16 E-Cores.

Intel Arrow Lake-S "Core Ultra 200" Desktop Lineup Features Two Primary Die Configurations: 8+16 "B0" & 6+8 "C0", Up To 4 Xe Cores For iGPU

The second leak today from @jaykihn covers the Intel Arrow Lake-S Desktop CPU configurations which will power the "Core Ultra 200" family. The lineup will be primarily built upon two dies that will include an 8+16 "B0" configuration and a 6+8 "C0" configuration. All SKUs will be derived from these two dies so let's get into the meaty details.

Starting with the flagship 8+16 "B0" CPU die, this configuration will be used to power the Core Ultra 9 and Core Ultra 7 CPUs which will come in 125W "K", 65W "Non-K" and 35W "T" flavors. Intel's Core Ultra 9 "Arrow Lake" Desktop CPUs will feature the 8+16 configuration with 4 Xe cores for a total of 24 cores & 24 threads. This will be followed by the Core Ultra 7 which will utilize the same "B0" die but adopt an 8+12 configuration. There will be two variants of this chip, one with 4 Xe cores and one without so an "F" variant to be precise.

The Core Ultra 5 "Arrow Lake-S" Desktop CPUs will feature several configurations derived from both "B0" and "C0" dies. The B0 dies will power the 125W Unlocked CPUs with 6 P-Cores, 8 E-Cores, and 4 Xe cores. There will also be an "F" variant without the iGPU cores. These chips will offer up to 14 cores and 14 threads.

The 65W Intel Core Ultra 5 stack will include four configurations, 6+8 (4Xe), 6+8 (3Xe), 6+8 (0Xe), 6+4 (0Xe Cores), & 6+4 (2Xe Cores). The 35W family will also be very similar except it will be missing the 6+8 (0Xe) SKU and will only utilize the "C0" die configurations. The Intel Arrow Lake CPUs will have a TJMax of 105C.

Intel Arrow Lake-S Desktop CPU Configurations:

Arrow Lake-S SKU	125W (Unlocked)	65W (Non-K)	35W (T)
Core Ultra 9	8+16 (4Xe Cores) "B0"	8+16 (4Xe Cores) "B0"	8+16 (4Xe Cores) "B0"
Core Ultra 7	8+12 (4Xe Cores) "B0"	8+12 (4Xe Cores) "B0"	8+12 (4Xe Cores) "B0"
Core Ultra 7	8+12 (0Xe Cores) "B0"	8+12 (0Xe Cores) "B0"	8+12 (0Xe Cores) "B0"
Core Ultra 5	6+8 (4Xe Cores) "B0"	6+8 (4 Xe Cores) "C0"	6+8 (4 Xe Cores) "C0"
Core Ultra 5	N/A	6+8 (3 Xe Cores) "C0"	6+8 (3 Xe Cores) "C0"
Core Ultra 5	6+8 (0Xe Cores) "B0"	6+4 (0Xe Cores) "B0/C0"	N/A
Core Ultra 5	N/A	6+4 (2Xe Cores) "B0/C0"	6+4 (2Xe Cores) "C0"

If we were to do the math based on the cache configuration reveal, the top die would feature 24 MB of L3 cache for the 8 P-Cores and 12 MB of L3 cache for the four E-Core clusters. That gives us 36 MB of L3 cache which matches the current Raptor Lake-S CPUs. For the L2 cache, the same die will feature 24 MB of L2 cache for the 8 P-Cores and 16 MB of L2 cache for the E-Cores which gives us 40 MB of total L2 cache. This gives us a combined 76 MB cache pool, or 12% more cache than Raptor Lake-S/HX CPUs which maxed out at 68 MB of combined cache.

Overall, the Intel Arrow Lake-S and Arrow Lake-HX CPUs should be a good addition to a fresh new platform in the form of LGA 1851 (800-series motherboards) and high-end laptops. It was already reported by us that the Arrow Lake-S lineup (K-Series) along with the first Z890 boards will be out in October and we recently got to see some performance figures based on ES2 samples. Intel will also introduce new Bartlett Lake-S Desktop CPUs in 2025 though those will be offered on the existing LGA 1700 socketed platforms.
