The Intel Raptor Lake processors are based almost exactly on the same microarchitectures that the Alder Lake.
According to the Intel TMA documents, both the large Raptor Cove Cores in the new CPUs as well as the existing Golden Cove Cores are identical at microarchitecture level. This is a true match of the microarchitecture. However, optimizations will be made to new cores. It was believed that Raptore Lake would be more like an Alder Lake upgrade than it would be a new generation. However, this is now confirmed.
We knew from the beginning that the smaller Gracemont cores would be able to go to the new CPUs with the same form. They would just become twice as many in maximum configuration.
As the first tests have shown, Raptor Lake is significantly faster than Alder Lake in many tasks. This is due to larger cache memory, higher frequencies and other improvements to large cores.
The next generation of CPUs will be Meteor Lake. These CPUs will be available by the end of next-year or early in 2024. They will receive new cores, both large and small, a new iGPU and a move to a new 7nm technology (Intel 4)
