AMD Ryzen 7 PRO 8840U

AMD Ryzen 7 PRO 8840U is an 8-core, 16-thread processor built on the Zen 4 architecture (Hawk Point codename) and manufactured on TSMC's 4 nm process. It sits in the 87th percentile of all CPUs tracked in the database, with an average benchmark score of 32171, placing it in a tight cluster of competitors where less than 1.1% separates the top and bottom performers. The chip carries a 28 W TDP, integrates Radeon 780M graphics, and supports DDR5 memory over a dual-channel interface.

Benchmark Performance

The Ryzen 7 PRO 8840U delivers an average benchmark score of 32171, which places it just behind a group of four closely matched rivals. The nearest competitor is the Intel Core i9-11900, which scores 32237, a mere 0.2% advantage over the AMD part. That gap is statistically negligible in real-world terms; the two processors are effectively interchangeable in aggregate performance. Moving to the AMD Ryzen 5 PRO 7645, the delta widens slightly to 0.8%, with the PRO 7645 scoring 32446. The Intel Core i5-14400F and Intel Core i7-12800H sit at 32508 and 32513 respectively, representing 1.0% and 1.1% leads over the 8840U. None of these differences exceed a single percentage point, so the 8840U is not outperformed by any meaningful margin — it is simply at the tail end of a very crowded performance band.

Diving into specific workload scores, the multi-core Cinebench results show a consistent pattern. In Cinebench R23 multi-core, the 8840U scores 20254, which is a strong result for a 28 W part. The R20 multi-core score of 8506 and R15 multi-core score of 2041 follow the same trend. Single-core performance is equally notable: Cinebench R23 single-core hits 2859, R20 single-core reaches 1200, and R15 single-core lands at 288. These numbers indicate that the Zen 4 architecture's IPC gains are fully realized even at this power envelope. The PassMark suite reinforces this, with a multithread score of 23829 and a single-thread score of 3671.

The gap between the 8840U and its rivals is so small that the data suggests the deciding factor for buyers should be platform features, not raw compute. A 1.1% deficit to the Core i7-12800H translates to roughly 342 points on the average benchmark scale, which is within run-to-run variance for most workloads. The 8840U's performance is best described as "class-competitive" — it neither leads nor lags in any meaningful way, sitting squarely in a four-way tie.

Who Should Consider It

Based on the benchmark scores, the Ryzen 7 PRO 8840U suits workloads that benefit from balanced multi-threading and strong single-core responsiveness. The Cinebench R23 multi-core score of 20254 indicates solid rendering capability for its power class, making it viable for 3D modeling, video encoding, and software compilation that scales across 8 cores and 16 threads. The PassMark integer math score of 88934 and floating-point math score of 51005 further support productivity tasks like spreadsheet manipulation, data analysis, and scientific computing. For office workloads, the PassMark single-thread score of 3671 ensures snappy UI interactions and fast document processing, while the data compression score of 271079 suggests efficient file archiving and database operations.

Gaming is a more nuanced recommendation. The 8840U's single-thread performance is strong enough for most game engines, but the integrated Radeon 780M graphics will be the limiting factor for demanding titles. The chip is better suited for cloud gaming or e-sports titles that rely heavily on CPU throughput rather than discrete GPU power. The passmark physics score of 1171 indicates adequate game physics simulation, but users seeking high-refresh 1080p gaming on integrated graphics should temper expectations. For creative professionals working on laptops, the 28 W TDP makes this a candidate for thin-and-light machines that still need rendering muscle, though the 4 nm process does not eliminate the thermal constraints of such chassis.

Single-Thread vs Multi-Thread Behavior

The Ryzen 7 PRO 8840U shows a balanced profile between single-thread and multi-thread performance, with no glaring imbalance. The Cinebench R23 single-core score of 2859 versus multi-core of 20254 yields a ratio of about 7.1:1, which is expected for an 8-core/16-thread part with good scaling. The PassMark single-thread score of 3671 and multithread score of 23829 produce a similar ratio of 6.5:1, confirming that the scheduler and cache hierarchy are efficient at distributing work across all cores. This balance means the chip does not sacrifice responsiveness for throughput or vice versa — a trait that benefits mixed workloads like streaming while gaming or compiling code while browsing.

The data implies that single-thread performance is not a bottleneck for this processor. A Cinebench R23 single-core score of 2859 places it in a range where most everyday applications, from web rendering to office suites, will feel instantaneous. Meanwhile, the multi-core scores indicate that heavily threaded tasks like video rendering or batch photo processing will utilize all 16 threads effectively. The PassMark extended instructions score of 18897 and data encryption score of 16383 show that AVX-512 or similar instruction sets are handled competently, which matters for scientific simulations and cryptographic workloads. Users who primarily run single-threaded legacy software will not be disappointed, but those who can leverage multi-threading will extract the full potential of the 8-core design.

How It Compares

Intel Core i9-11900: The 8840U trails this Intel part by 0.2% in average score, a difference of just 66 points out of 32237. The two are effectively tied, with the 8840U offering a newer architecture and lower TDP, though the i9-11900 was a desktop flagship in its generation. Benchmark results show no practical performance winner here.

AMD Ryzen 5 PRO 7645: This AMD sibling leads the 8840U by 0.8%, scoring 32446 versus 32171. The 275-point gap is marginal, but it is notable that a Ryzen 5 part with presumably fewer cores can match or slightly exceed the 8-core 8840U in aggregate. This suggests the 8840U's power constraints may cap its multi-core ceiling relative to higher-TDP parts.

Intel Core i5-14400F: The i5-14400F scores 32508, a 1.0% lead over the 8840U. A 337-point difference is still within noise for most applications, but the i5's desktop-oriented design likely allows sustained boost clocks that the 8840U cannot match under its 28 W envelope. The 8840U counters with integrated graphics and PRO manageability features absent from the i5.

Intel Core i7-12800H: This mobile H-series chip leads by 1.1%, scoring 32513. The 342-point gap is the largest among the rivals, yet still under 1.2%. The i7-12800H has a higher TDP class, which explains its slight edge in multi-threaded loads, but the 8840U offers a more power-efficient package with a 28 W TDP versus the i7's typically higher draw.

Platform and Compatibility

The Ryzen 7 PRO 8840U uses AMD Socket FP7, with part numbers 100-000001317 (FP7r2) and 100-000001377 (FP7). It is based on the Zen 4 architecture with the Hawk Point codename, representing the third generation of Ryzen 7 PRO processors on this node. The platform supports DDR5 memory in a dual-channel configuration, delivering a memory bandwidth of 89.6 GB/s. ECC memory is supported, which is a critical feature for workstation and server deployments where data integrity is paramount. The CPU provides 20 PCIe Gen 4 lanes, enabling fast NVMe storage and discrete GPU connectivity, though the integrated Radeon 780M graphics eliminate the need for a separate GPU in many office and light-creative scenarios.

The production status is listed as Active, with a release date of April 15, 2024. The market segment is classified as Server/Workstation, which aligns with the PRO branding that typically includes enterprise management features. The multiplier is locked, meaning overclocking is not supported, but this is expected for a PRO part aimed at stability. The upgrade path is limited to the FP7 socket ecosystem, which is primarily mobile-focused, so users should plan for this chip to serve the life of the system rather than expect future drop-in upgrades. The 4 nm process and 25,000 million transistors on a 178 mm² die indicate a dense, modern design that should offer good longevity in embedded or laptop applications.

Power and Thermals

The Ryzen 7 PRO 8840U has a TDP of 28 W, which classifies it as a low-power part suitable for thin-and-light laptops and compact workstations. This power envelope is notably lower than desktop parts like the Intel Core i9-11900 or i5-14400F, which typically operate at 65 W or higher, yet the 8840U manages to stay within 1.1% of their aggregate performance. The 4 nm TSMC process is the key enabler here, allowing high clock speeds (up to 5.10 GHz boost) without excessive power draw. The base clock of 3.30 GHz ensures sustained performance under load, while the boost clock handles bursty single-thread tasks.

For cooling, a 28 W TDP implies that a modest thermal solution suffices — a single heat pipe with a small fan in a laptop, or a low-profile cooler in a mini-PC. The data does not specify a cooler requirement, but the power class suggests passive cooling might be possible in well-ventilated chassis with adequate airflow. The integrated Radeon 780M graphics share the same thermal budget, so sustained gaming or GPU compute will push the total package power higher than the CPU-only TDP. Users should expect quiet operation under typical office loads, with fan noise increasing during sustained multi-core rendering or gaming sessions. The locked multiplier and 28 W ceiling mean there is little headroom for manual tuning, but the chip's efficiency at stock settings is a strong selling point for battery-powered devices.
