AMD Ryzen AI 5 PRO 340

The AMD Ryzen AI 5 PRO 340 is a 6-core, 12-thread mobile processor built on Zen 5 and branded under the Krackan Point codename. Produced on TSMC's 4 nm process with a 195 mm² die, it runs at a 2000 MHz base clock and a 4.80 GHz boost clock inside a 28 W TDP envelope. Its average benchmark score of 25099 places it in the 82nd percentile of all CPUs, and its closest listed rivals all land within a few tenths of a percent of that average.

Benchmark Performance

The nearest-rivals data paints a picture of near parity at the top level. The AMD Ryzen AI 5 PRO 340 averages 25099, while the AMD EPYC 9474F scores 25103, a 0% difference. The AMD Ryzen 5 8400F is 0.1% behind, the AMD Ryzen 7 2700X is 0.2% behind, and the Intel Core i7-13620H is 0.4% ahead. In other words, the overall benchmark average does not separate this processor from its nearest competitors by any meaningful margin.

| CPU | Average Score | Delta |

|---|---|---|

| AMD Ryzen AI 5 PRO 340 | 25099 | — |

| AMD EPYC 9474F | 25103 | 0 |

| AMD Ryzen 5 8400F | 25064 | 0.1 |

| AMD Ryzen 7 2700X | 25057 | 0.2 |

| Intel Core i7-13620H | 25201 | -0.4 |

Raw Cinebench results reinforce the position. In Cinebench R23, the processor scores 16131 multicore and 2277 singlecore. The older Cinebench R20 run returns 6775 multicore and 956 singlecore, while Cinebench R15 shows 1626 multicore and 229 singlecore. These numbers are internally consistent: across three generations of the Cinebench workload, the multicore result is a large multiple of the singlecore result, which is expected for a 6-core, 12-thread processor.

The PassMark suite provides additional context. The multithread score is 18999, and the single-thread score is 3778. Integer math reaches 62910, floating point math reaches 39303, and extended instructions score 15404. Data compression is a notable strength at 218369, while random string sorting scores 23898. The single-thread and multithread PassMark numbers align with the Cinebench pattern: this is a balanced mobile chip, not a specialist in any one synthetic workload.

Power and Thermals

The thermal design point is 28 W. That places the Ryzen AI 5 PRO 340 in the low-power mobile segment, where cooling is expected to be modest rather than bulky. The 4 nm process from TSMC is the manufacturing foundation behind that envelope, and the die area of 195 mm² gives context for the physical package.

The base clock of 2000 MHz is the sustained floor, while 4.80 GHz is the boost ceiling. At a 28 W TDP, the boost clock is best understood as a capability for short, high-frequency bursts; the base clock defines the continuous-load baseline. The spread between 2000 MHz and 4.80 GHz is large, which is characteristic of a mobile part designed to ramp quickly for single-thread work and then settle back under sustained multi-thread load.

For cooling tier, a 28 W processor does not require a high-end desktop cooler. It belongs in a thin-and-light laptop or a compact mobile chassis. The data does not include temperature measurements, but the TDP class alone indicates that thermal management is far less demanding than for high-power desktop or workstation CPUs.

Who Should Consider It

Office and productivity users are the most obvious fit. The PassMark single-thread score of 3778 and multithread score of 18999 show enough throughput for everyday applications. The data compression score of 218369 is particularly relevant for file archiving, backup tasks, and large data transfers. With 6 cores and 12 threads, the processor can handle several background tasks alongside interactive work without running out of thread resources.

Creative users who work on rendering, encoding, or code compilation will find the Cinebench R23 multicore score of 16131 useful. Integer math at 62910 and floating point math at 39303 indicate solid compute throughput for workloads that exercise the CPU rather than the GPU. That said, this is a 28 W mobile part, so it is not a substitute for a high-core-count desktop processor. The 82nd percentile overall standing means it beats the majority of CPUs in the database, but not the extreme high end.

For gaming systems, the integrated Radeon 840M means the CPU can drive display output without a discrete GPU. The CPU-side benchmark results are strong enough for a mobile gaming laptop that pairs it with a separate graphics solution, but the integrated GPU is the limiting factor for gaming workloads unless a discrete GPU is present. A system built around this processor should be treated as a general-purpose mobile platform that can also do light GPU-accelerated work.

Mobile buyers should note that the market segment is Mobile, the production status is Active, and the release date is 2025-01-05. It is a current-generation processor for new laptops rather than an older desktop chip pressed into service.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is clear from the benchmark data. PassMark single-thread is 3778, while multithread is 18999. Cinebench R23 shows a singlecore score of 2277 against a multicore score of 16131. The multi-threaded numbers are much larger in absolute terms, as would be expected from a processor with 6 cores and 12 threads.

Single-thread performance drives how responsive the machine feels in lightly threaded tasks such as web browsing, document editing, and many older applications. The Cinebench R23 singlecore result of 2277 and PassMark single-thread result of 3778 indicate that this processor does not handicap per-core speed to reach its power target. Those scores are competitive for a mobile part in the 28 W class.

Multi-thread performance matters for rendering, video encoding, compilation, and other workloads that can use all available cores. The Cinebench R23 multicore score of 16131 demonstrates that the 6 cores and 12 threads scale well under parallel load. The PassMark multithread score of 18999 confirms that the chip can maintain throughput when all threads are active.

Because the overall average score is within 0.4% of all four nearest rivals, the processor does not sacrifice one kind of performance to achieve the other. It keeps single-thread responsiveness and multi-thread throughput in the same competitive band, which makes it a predictable choice for mixed workloads.

Platform and Compatibility

The processor is built on the Zen 5 architecture with the codename Krackan Point and the generation label Ryzen AI (Zen 5). It uses AMD Socket FP8, which defines the physical platform for any laptop design. The part number is 100-000001600, and the market segment is Mobile.

Memory support includes DDR5 and LPDDR5X over a dual-channel bus. The rated memory bandwidth is 89.6 GB/s, and ECC memory is supported. This is a useful feature for certain professional or data-integrity-focused workloads, though the mobile platform still limits how much memory a given system can use.

The PCIe implementation is Gen 4 with 16 lanes from the CPU only. That is the lane budget available to the processor itself; it is not a chipset lane count. System designers can use those lanes for discrete GPUs, NVMe storage, or other Gen 4 devices as needed.

Integrated graphics are provided by Radeon 840M, so no discrete GPU is mandatory for basic display output. The base clock is 2000 MHz, the boost clock is 4.80 GHz, and the cache layout is 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3. The process node is 4 nm from TSMC, and the die size is 195 mm².

As an FP8 mobile processor, compatibility is tied to that socket. The production status is Active, so it is a current part rather than a discontinued one. The release date of 2025-01-05 places it in the modern mobile lineup, and the 28 W TDP makes it suitable for systems where power efficiency and moderate performance need to coexist.
