Common features of Ryzen 7045 notebook CPUs:

  • Socket: FL1.
  • All the CPUs support DDR5-5200 in dual-channel mode.
  • L1 cache: 64 KB (32 KB data + 32 KB instruction) per core.
  • L2 cache: 1 MB per core.
  • All the CPUs support 28 PCIe 5.0 lanes.
  • Includes integrated RDNA 2 GPU on the I/O die with 2 CUs and clock speeds of 400 MHz (base), 2.2 GHz (boost) [i].

  1. ^ Self identifies as "AMD Radeon 610M". See RDNA 2 § Integrated graphics processors (iGPs).
  2. ^ Only one of the two CCXes has additional 64 MB of 3D V-Cache. Only the CCX without 3D V-Cache will be able to reach the maximum boost clocks. The CCX with 3D V-Cache will clock lower.
