AMD Ryzen AI 5 PRO 340 socket: FP8

What the Ryzen AI 5 PRO 340 is

The Ryzen AI 5 PRO 340 is the entry business SKU of the Krackan Point PRO family. Three full-size Zen 5 cores and three compact Zen 5c cores give 12 threads at 2.0 GHz base, with the fast cores boosting to 4.8 GHz and the compact cores to 3.4 GHz. Cache totals 6 MB of L2 plus 16 MB of L3. The chip is built on TSMC 4 nm as a single monolithic die that is smaller than Strix Point, and its default TDP is 28 W inside a 15 to 54 W configurable range.

Graphics come from 4 RDNA 3.5 compute units as Radeon 840M at up to 2900 MHz. That size covers office work, video calls and everyday displays without a discrete card, which is exactly what entry business laptops need. The XDNA 2 NPU reaches up to 50 TOPS, with combined platform throughput up to 59 TOPS. Background effects, transcription and on-device assistance run on the NPU while the CPU cores handle the applications in front of the user.

Against the 8-core PRO 350 above it, the PRO 340 keeps the same L3 cache, NPU rating and PRO management set with two fewer cores and a smaller GPU. Office fleets that buy hundreds of machines save money per seat without losing manageability. AMD lists a March 27, 2025 launch date for this SKU, and it shipped in cost sensitive business lines through that year with AMD PRO Technologies for remote management and hardware backed security.

Socket and motherboard compatibility

The chip solders into FP8, the 25 × 40 mm BGA that carries recent AMD mobile generations, so it cannot be removed or swapped after manufacture. Buyers choose a complete laptop with fixed processor, memory and cooling, and service means board replacement. There is no socket lever, no retention bracket and no secondhand upgrade market for the processor itself. The LGA, PGA and BGA: CPU package types explained guide explains how soldered packages differ from socketed ones.

Entry business laptops pair this APU with DDR5 SODIMM slots in serviceable chassis or with soldered LPDDR5X in thinner ones. Firmware and management support come from the laptop maker, so the support page for the exact laptop model is the reference that matters. A failed board is replaced as a unit under the service plan.

Memory, PCIe and cooling

Systems pair the PRO 340 with DDR5 SODIMM modules or soldered LPDDR5X, over two channels to 256 GB. DDR5-5600 is the fastest socketed speed AMD lists for the platform, while soldered LPDDR5X reaches 8000 MT/s for extra graphics bandwidth. ECC works where the platform supports it, which suits reliability sensitive deployments. Soldered memory sizes freeze at purchase, and Copilot+ features need 16 GB or more in the system.

Expansion comes from 16 usable PCIe Gen4 lanes for NVMe storage and add-on devices. USB4 ports from the SoC handle docking stations, fast external drives and extra displays, with up to four monitors supported from the integrated graphics. Most office desks get their screens and wired networking from a dock rather than from inside the chassis.

Cooling spans 15 to 54 W around the 28 W default and belongs to the laptop maker, with heat pipes and fans drawn for the configured TDP of each model. Boost behavior tracks power and temperature on each machine, so the same APU scores differently in a thin ultrabook and a thicker performance chassis. Fleet buyers should compare complete laptop models on noise and sustained performance, not on the APU name alone.

Upgrade paths

Soldered laptop silicon cannot be upgraded, so buyers pick the core count, graphics size and memory at purchase and judge used machines on battery health, panel quality and chassis condition. The PRO 340 suits buyers who equip large office fleets with a current generation 6-core at a modest per-seat price. Teams with heavier multitasking needs should step to an 8-core PRO part at the same 28 W envelope.

The PRO badge is the deciding factor against the consumer Ryzen AI 5 340, which shares the Krackan Point die and clocks but lacks the fleet management set. A company that images and manages many laptops buys PRO; a home buyer with one machine gains nothing from it. Compare complete laptops on display, keyboard, battery and service options, which decide daily experience more than the APU badge.
