What the Ryzen 5 7640HS is
The Ryzen 5 7640HS is a 6-core and 12-thread mobile APU that AMD launched on January 3, 2023 for performance thin laptops. 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 178 sq mm die uses TSMC 4 nm and carries a 45 W default TDP inside a 35 to 54 W configurable range. Part numbers cover FP7, FP7r2 and FP8 packages for different board designs.
Radeon 760M graphics with 8 compute units at up to 2600 MHz handle creation displays. A Ryzen AI NPU with 10 TOPS covers early AI effects. Shared DDR5-5600 or LPDDR5X-7500 keeps board cost in check for the 6-core performance tier.
Performance thin buyers who want high base clocks without 8-core cost fit here. The 4.3 GHz base sustains jobs where 28 W U parts dip. Shoppers who need 8 cores for parallel creation should take Phoenix 8-core HS parts instead, since this 7640HS prioritizes base speed.
Socket and motherboard compatibility
The 7640HS solders to FP8 with 35 to 54 W cooling in larger thin bodies. No socket upgrade exists. Firmware sets power between balanced and performance modes.
Boards use DDR5 SODIMM or soldered LPDDR5X in two channels up to 256 GB. NVMe Gen4 plus USB4 covers storage and docks. Vendor power profiles decide sustained behavior.
HS shoppers compare Phoenix 6-core parts on 0.8 GHz base gaps. The 7640HS leads U twins on sustained speed. The LGA, PGA and BGA: CPU package types explained guide explains soldered mobile.
Memory, PCIe and cooling
DDR5-5600 or LPDDR5X-7500 in two channels is the menu. Dual modules help the 760M GPU. Soldered size is fixed where fitted.
PCIe Gen4 x20 serves NVMe, wireless and displays. Fixed wiring means options vary.
Cooling is performance thin 45 W with dual fans on many models. No retail cooler ships with soldered parts.
Upgrade paths
No CPU upgrade exists. The Phoenix 6-core decision is HS versus U at order time. RAM and NVMe can grow where fitted.
The next platform is Hawk Point with stronger NPU. A working 7640HS lasts performance thin years.
