What the Ryzen 5 7640H is
The Ryzen 5 7640H is a 6-core and 12-thread mobile APU for performance laptops on the Phoenix family. Six Zen 4 cores with simultaneous multithreading run at 4.3 GHz base and up to 5.0 GHz boost, plus 6 MB of L2 and 16 MB of L3. The TSMC 4 nm die carries a 45 W default TDP for larger thin bodies with gaming-capable cooling. It shares silicon with the 7640HS tuned for H-series board firmware.
Radeon 760M graphics with 8 compute units cover creation displays. Shared DDR5 or LPDDR5X keeps board cost down for the 6-core H tier. Board makers pair H parts with stronger power delivery than U parts for sustained clocks.
Standard laptop buyers fit here. The H suffix marks vendor-tuned firmware for mainstream gaming bodies. Shoppers who need efficient HS tuning should compare the AMD Ryzen 5 7640HS with the same clocks instead, since silicon matches and firmware differs.
Socket and motherboard compatibility
The 7640H solders to FP8 with 45 W cooling. No socket upgrade exists. Board firmware sets power delivery for H bodies.
Boards use DDR5 SODIMM or LPDDR5X in two channels. NVMe plus USB4 covers storage and docks. Vendor profiles decide behavior.
H shoppers compare H versus HS twins at equal clocks. The 7640H matches HS speed with H firmware. The LGA, PGA and BGA: CPU package types explained guide covers soldered design.
Memory, PCIe and cooling
DDR5-5600 or LPDDR5X-7500 in two channels is the menu. Dual modules help graphics. Soldered size is fixed where fitted.
PCIe Gen4 x20 serves storage, wireless and displays. Options vary by model.
Cooling is performance 45 W with gaming-capable fans. No retail cooler ships with soldered parts.
Upgrade paths
No CPU upgrade exists. The H decision is made at order time. RAM and NVMe can grow where fitted.
The next platform is Hawk Point. A working 7640H lasts performance laptop years.
