AMD Ryzen 3 7320C socket: FT6

What the Ryzen 3 7320C is

The Ryzen 3 7320C is the 4-core Chromebook version of Mendocino that AMD announced on May 23, 2023 for education and front-line laptops. Four Zen 2 cores with multithreading run at 2.4 GHz base and up to 4.1 GHz boost, with 2 MB of L2 and 4 MB of L3 for 6 MB total. The 100 sq mm TSMC 6 nm die sips 15 W for thin fan-cooled Chromebook bodies with ChromeOS. It matches the 7320U laptop part in silicon but tunes firmware for Chromebook power and management.

Radeon 610M with 2 RDNA 2 compute units to 1900 MHz drives the Chromebook panel plus up to three external 4K displays through board ports. The media block accelerates video calls and streaming that dominate classroom use, while Wi-Fi 6 and Bluetooth 5.2 come through board modules. Soldered LPDDR5 to 5500 MT/s in two channels to 16 GB feeds CPU and GPU together, with no DIMM slots for later changes.

Schools pick the 7320C for responsive browsing, docs and conferencing with long battery life rather than for heavy creation. AMD cites up to 17 hours of expected battery in its test configuration, though real life varies with display and radio use. Buyers who need more single-thread speed step to the 7520C on the same FT6 platform, while buyers who need Windows software look to FP6 or FP8 laptops instead.

Socket and motherboard compatibility

The 7320C solders to FT6 on Chromebook mainboards with no socketed option. Board design decides display wiring, storage form and wireless modules rather than chip compatibility. FT6 does not cross to FP6 or FP8, since ball maps and memory types differ. The AMD product page lists FT6 under CPU socket as the fit reference.

There is no desktop chipset to choose. Four PCIe Gen3 lanes from the APU serve NVMe and wireless, while eMMC options appear on value models. ChromeOS firmware and Titan C security wiring belong to the Chromebook maker. Owners should check the maker page for storage type and memory size before buying, since both are fixed at order time.

Memory, PCIe and cooling

LPDDR5 soldered memory to 5500 MT/s in two channels to 16 GB is the only memory for 7320C Chromebooks. Bandwidth near 88 GB per sec shared between CPU and 610M graphics suits web and video loads. No DDR4 or SODIMM options exist on Mendocino C boards, and soldered capacity cannot be added to later. Buyers who keep devices for years should choose 8 GB over 4 GB where offered.

PCIe Gen3 with 4 lanes from the APU typically wires NVMe or eMMC storage plus wireless. External display support comes from the 610M through HDMI, DisplayPort and USB-C alternate mode. Cooling is a small fan and spreader for 15 W with quiet classroom acoustics. Sustained clocks follow thermal headroom, so blocked vents slowlong video calls.

Upgrade paths

No CPU or memory upgrade exists on soldered FT6 Chromebook boards. Storage moves depend on the model: NVMe models accept larger drives where the slot opens, while eMMC models are fixed. Wireless modules follow the maker parts list. Battery replacement through service extends life more than any chip change.

The in-socket step up is the Ryzen 5 7520C with higher clocks on the same FT6 platform for faster everyday response. Outside FT6, Windows laptops on FP8 or FP6 add software breadth for buyers who outgrow ChromeOS. For current 7320C owners the practical path is storage care and display accessories rather than a chip swap.
