Over the weekend a slide leaked on the Intel's pending Alder Lake, you know the BIG.little core design processors that will follow later this year, after Rocket Lake. The slide indicates the 10nm processors will receive support for DDR5 and PCIe 5.0

Intel itself has indicated a release late this year for this 10nm lga1700 socket processor series for notebooks and desktops. However leaked marketing slides published by VideoCardz include showing a thing or two more. Performance in single-threads could be  'up to twenty percent better. Note, It's not indicated what intel is actually comparing to, (Rocket Lake or Tiger Lake)

The slides also show that multithreaded performance would be 'up to twice' better as well as usage of Gracemont cores. Alder Lake CPUs would get two types of cores. In addition to faster Golden Cove cores with hyperthreading, the CPUs also get energy-efficient Gracemont cores without hyperthreading, which should improve multithreaded performance. The CPUs will utilize hardware-controlled scheduling to distribute tasks between the different cores.

Alder Lake will be get up to eight Golden Cove cores and up-to eight Gracemont cores, so that's in one with previous leaks we've seen, 16 cores and 24 threads. Interesting to notice is that Alder Lake CPUs have sixteen PCIe 5.0 and four PCIe 4.0 lanes. System memory-wise Alder Lake supports both DDR5 and DDR4 memory.

Intel confirmed the arrival of Alder Lake at CES in January but shared only a few details at the time.
