Intel Raptor Lake Chip captured in full glory during Intel Tech Tour Israel Event

The editor of Hardwareluxx, Andreas Schilling, tweeted a full wafer photo that revealed the first die shot of Intel’s Core i9-13900K, the top Raptor Lake CPU. IDC (Intel Design Center), which is situated in Haifa, Israel, has received invitations from tech journalists from all over the world. The FAB28, a top manufacturing facility where Intel’s next Raptor Lake CPUs are produced, was open to the tech and media community.

Just a few miles south of Tel Aviv in Israel’s Kiryat Gat is where you’ll find the cutting-edge factory. In that location, Intel produced press hold wafers using its newest Raptor Lake silicon.

The wafer that was displayed has the entire Raptor Lake-S Desktop CPU die, which consists of 16 upgraded Gracemont cores and 8 P-cores based on Raptor Cove cores. Up to 24 cores and 32 threads are combined. Each die has eight E-cores, which are visible on the wafer. 

Next, we have the larger P-cores, which have a faint brown hue and appear larger. In contrast to the Alder Lake CPUs, which only have two clusters, the four E-cores combine to form four such clusters on the silicon.

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 – 2 MB (2 x 2 = 4 MB)
Raptor Lake Total Cache (L3+L2) = 68 MB
Alder Lake Total Cache (L3 + L2) = 42 MB

According to estimates, each Raptor Cove core in Intel’s 13th generation Raptor Lake CPUs will have 2 MB L2 and 3 MB L3 cache, while each Gracemont Cluster would have 4 MB L2 and 3 MB L3 cache. With 16 MB (2×8) for P-cores & 16 MB (4×4) for E-cores, this will give us a total of 36 MB L3 cache across all cores.

The 13th generation Intel Raptor Lake CPUs have a somewhat larger die, measuring 23.8 x 10.8mm or 257.04mm, as seen in deleted die pictures. The Alder Lake top-die’s dimensions are 20.4 x 10.2mm, or 208.08mm2, for reference. The new CPUs will feature more Gracemont E-Cores and larger L2/L3 caches than the 12th Gen components, which explains the rise of 24% in die area.

The top-tier Raptor Lake CPU is the Intel Core i9-13900K, which has 24 cores and 32 threads in an 8 P-Core and 16 E-Core architecture. The CPU is set up to run at 3.0 GHz base speed, 5.8 GHz single-core boost (1-2 cores), and 5.5 GHz all-core boost. The CPU has a 125W PL1 rating that goes up to 250W and 68 MB of shared cache.

Intel is expected to unveil its 13th Gen Raptor Lake CPU on the 27th of September during the Innovation event with a retail launch planned for October 2022.
