Intel Raptor Lake vs. Ryzen 7000: Official specifications of the new CPU generation leaked

The secret of Intel’s 13th CPU generation, Raptor Lake, seems to have been revealed a good 20 days before the actual presentation. Because Igor’s Lab was there and published a number of presentation slides from Intel on its website, which provide information about the first six processors and the supported platform.

The first Raptor Lake CPUs with Z790 chipset

The flagship CPU is known to be the Core i9-13900K with 24 cores and 32 threads, of which 8 P cores and 16 E cores, a doubling on the E cores compared to Alder Lake. The TDP (here the maximum turbo performance) is 253 W for the 13900K, while a clock rate of 5.8 GHz can be achieved with the help of the Thermal Velocity Boost. According to Intel’s slides, only the Core i9-13900K has the TVB and none of the other models listed.

This is followed by the Core i7-13700K with eight P and E cores each and a turbo clock of up to 5.4 GHz. Like the 13900K, this should have a maximum TDP of 253 W. The third CPU in the group is the Core i5-13600K with six P and eight E cores, which should be able to clock at 5.1 GHz. However, this is without the Turbo Boost Max 3.0 that both the i7 and the i9 have. The TDP of this model, on the other hand, is significantly lower at 181 W, while the “Processor Base Power” is identical for all models and is 125 W. In addition to the three K processors, the KF variants are also listed, which have the same specifications but have to do without integrated graphics.

As for the memory support of the Raptor Lake processors, Intel states DDR4-3200 and DDR5-5600. Previously, DDR5-4800 memory was assumed at this point. Also new from Alder Lake are increased L2 and L3 caches on i5K CPUs and beyond. So should citing 3Dcenter.org CPUs including use Alder Lake chips.

There are also innovations on the chipset side. The platform support for the new CPUs applies to both Intel’s 600 and 700 chipsets, but the new Z790 chipset gets an upgrade for the PCI Express 4.0 lanes and a downgrade for the PCI Express 3.0 -Lanes. The total of 38 lanes of the 600 series are also retained in the Z790, but the division has shifted to eight PCI-E 3.0 lanes and 20 PCI-E 4.0 lanes. In addition, the Z790 now has five USB 3.2 Gen 2×2 ports at 20 Gbps instead of four.

After the official data on the first Ryzen 7000 CPUs became known last week and information about Raptor Lake has now leaked, a comparison of the two processor generations can already be made. Intel has more cores and the same number of threads, but less cache overall. Raphael only supports DDR5 memory, while Raptor Lake also supports DDR4. When it comes to clock, the two competitors don’t take too much from each other. Intel will officially announce Raptor Lake on September 27th as part of its innovation event. There will probably then be the same presentation slides to see.
