The 13th Generation Intel Core CPU “Raptor Lake” are now really without secrets thanks to the leaks of the last few days from Wccftech And Igor’s Lab. The models at launch, belonging to the K and KF series, will be six: Core i9-13900K and KF, Core i7-13700K and KF and Core i5-13600K and KF. The K indicates, as always, the unlocked multiplier, the F is instead synonymous with the deactivated integrated GPU, an aspect that allows Intel to place the chip at a lower price level than the K models.
We have long known that the main novelty of this generation of Intel chips, which succeeds the Alder Lake solutions, will be represented by the doubling of E-cores. The Core i9-13900K will therefore offer well 24 cores and 32 threads, thanks to 8 P-cores with Hyper-Threading and 16 E-cores. The 12900K, with 8 P-cores and 8 E-cores, offers 16 cores and 24 threads instead.
The Raptor Lake architecture also features a increased L2 cache. With regard to i P-core you climb from the 1.25 MB of Alder Lake a 2 MBin the case of E-core cluster (4 cores each) you get to touch i 4 MB against the previous 2 MB. It follows that in the best implementation we will have 32 MB of L2 cache, against 14 MB of the 12900K. There L3 cache maximum, however, it will rise to 36MB from the previous 30MB due to the two extra E-core clusters (3 MB each).

According to the information released by the leaks, i P-core of the Core i9-13900K will be set at a base clock of 3 GHz, but thanks to the various Turbo Boost algorithms (it is admitted and not granted that the cooling and power supply allow it) push up to 5.8GHz. The E-cores, on the other hand, will be accompanied by a base clock of 2.2 GHz and a Turbo Boost of 4.3 GHz.
The 12900K, we recall, sees the P-cores with a base clock of 3.2 GHz but can accelerate up to 5.2 GHz. The E-cores, on the other hand, operate at 2.4 GHz (base) and go up to at 3.9 GHz (boost).
These values, coupled with the extra cores, will force Intel a increase of Maximum Turbo Power to 253W compared to 241W touched by 12900K. In terms of technical specifications, the update of the memory controller to support basic le DDR5-5600, a leap from Alder Lake’s DDR5-4800. CPUs will continue to work on motherboards with DDR4 memory as well. There will be no news for the SKUs with integrated graphics, which will remain the HD Graphics 770.
The Core i7-13700K will offer 4 cores and 4 more threads than the Core i7-12700K, going up to 16 cores and 24 threads in total from the previous 12 and 20 threads. As a result of the changes, the 13700K will have 30MB of L3 cache and 24MB of L2 cache. The P-core clock on this model will start at 3.4 GHz base to go up to a maximum of 5.4 GHz. That of the E-cores will go from 2.5 GHz to go up to 4.2 GHz.
The 12700K, for comparison, starts at 3.6 GHz and goes up to 5 GHz in the case of the P-core, while in the case of the E-core the clocks are respectively 2.7 / 3.8 GHz. Interesting the value of the Maximum Turbo Power, which will pass from 190W of 12700K to 253W of Core i7-13700K.

We continue the discussion with the Core i5-13600Kprocessor with 14 cores (6 P-core and 8 E-core) and 20 threads, which will be joined by 24 MB of L3 cache and 20 MB of L2 cache. The Core i5-12600K has the same number of P-cores but 4 fewer E-cores, as well as obviously less L2 and L3 cache.
The P-cores will be set to basic 3.5 GHz and can go up to a maximum of 5.1 GHz, while the E-cores will operate at 2.6 GHz base and then touch the 3.9 GHz in Turbo Boost. In the case of the 12600K, the clock of the P-cores is 3.7 / 4.9 GHz, while the E-cores operate at 2.8 / 3.6 GHz. The Maximum Turbo Power rises from 150W of the 12600K to 181W of the 13600K. .
Looking at the numbers, it can be seen how Intel has reduced the base clock by 200 MHz of P-core and E-core, but have shot high in terms of Turbo Boost, widening the meshes of the TDP. On the other hand these CPUs are produced with the Intel 7 process, the same as the Alder Lake CPUs.
Probably starting in early 2023, the range will expand with models Core i9-13900 (24 total cores, 8P + 16E), Core i7-13700 (Total 16 cores, 8P + 8E), Core i5-13600 (14 total cores, 6P + 8E), Core i5-13500 (14 cores, 6P + EC) e Core i5-13400 (Total 10 cores, 6P + 4E). All of these solutions will have a 65W Processor Base Power, but there will also be two 35W T models named Core i9 13900T and Core i7 13700T. The new documents do not mention the Core i3, but previous rumors also spoke of a Core i3-13100 formed by only 4 P-cores.

It should be noted that for the Intel Core 13000 should continue to leverage Alder Lake dies (C-0 and H-0) for low-mid-range CPUs, using the new B-0 Raptor Lake die only starting from the Core i5-13600K up to the Core i9-13900K. This can be deduced from the slide above in which the greater L2 cache is placed next to the “Core i5K” CPUs onwards.
As for the platform, we have already said over and over that the Core 13000 they can be installed on 600 series motherboards after BIOS update, but the chipsets of the 700 series will also arrive starting from Z790.

Compared to the Z690, Intel would have decided to reduce the PCIe 3.0 lanes from a maximum of 16 to 8, to increase the PCIe 4.0 lanes from a maximum of 12 to 20. To these lines, 4 are added by the CPU, a number that should remain unchanged. Same thing for PCIe 5.0, managed by CPUs with up to 16 lanes, although in this case they will be divisible in x8-x8 configuration to support the new generation M.2 PCIe 5.0 SSDs. Finally, Intel will bring support for USB 3.2 Gen 2×2 (20 Gbps) from up to four to five ports.
Intel will formalize the new range of Core CPUs on September 27 at the Intel InnovatiON eventin view of a market debut of processors and motherboards during the month of October.
