# AMD Ryzen 7 8840HS + NVIDIA GeForce RTX 4080 Mobile: A High-Performance Laptop Duo

This pairing combines AMD's 8-core Zen 4 "Hawk Point" APU with NVIDIA's flagship Ada Lovelace mobile GPU, placing the system at the 83rd percentile overall against all laptop configurations. The CPU sits at the 84th percentile among all processors, while the GPU holds the 81st percentile position among all graphics cards, indicating a well-matched, high-end mobile platform. The data paints a picture of a system designed for demanding multitasking and visually intensive workloads, though the absence of measured FPS data for this exact combination requires careful estimation of gaming performance based on the available benchmark scores.

CPU Analysis

The AMD Ryzen 7 8840HS is a mobile processor built on TSMC's 4 nm process node, featuring 8 cores and 16 threads based on the Zen 4 architecture. Its base clock of 3.30 GHz can boost up to 5.10 GHz, a substantial frequency range that allows the chip to scale from power-efficient light workloads to bursty, high-performance tasks. The 25,000 million transistors are packed into a 178 mm² die, codenamed Hawk Point, which represents the 8000 series iteration of AMD's mobile lineup. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 16 MB L3 pool, providing ample fast storage for active data.

Benchmark results show a processor that is decisively multi-core capable. In Cinebench R23, the 8840HS scores 13,082 in multi-core and 1,737 in single-core tests. The multi-core figure is approximately 7.5x higher than the single-core score, reflecting the scaling efficiency of the 8-core/16-thread design under full load. Geekbench results reinforce this, with a multi-core score of 10,104 and a single-core score of 1,899. The PassMark suite reveals specialized strengths: the integer math score of 90,382 and floating point math of 52,582 indicate strong general compute performance, while the extended instructions score of 20,714 suggests solid SIMD throughput for workloads like encryption or media processing.

Relative to its nearest rivals, the 8840HS is essentially tied with the AMD Ryzen 5 7645HX, showing a deltaPct of 0.0%. It trails the AMD Ryzen 9 3900XT by only 0.2%, despite the latter being a desktop-class chip with more cores, and it leads the AMD Ryzen 5 240 and Intel Core Ultra 7 255H by 0.4% each. These tight margins place the 8840HS in a competitive bracket where small clock differences and thermal headroom often decide real-world performance. The 28 W TDP is notably low for the performance on offer, suggesting that laptop vendors can pair this CPU with thinner cooling solutions while still delivering strong multi-threaded results.

The integrated Radeon 780M graphics provide a baseline display output and light 3D acceleration, though the discrete RTX 4080 Mobile will handle all demanding rendering tasks. PassMark data compression (292,888) and encryption (17,650) scores indicate that the CPU handles data-heavy background tasks efficiently, which matters for system responsiveness during gaming or content creation sessions. The single-thread score of 3,626 in PassMark confirms that the 5.10 GHz boost clock delivers tangible gains in lightly-threaded applications like legacy software or certain game engines.

Benchmark Performance

The combined benchmark profile places this system at the 83rd percentile overall, which is a strong indicator of high-end laptop performance. The CPU's average benchmark score of 33,667 comes from a battery of tests spanning Cinebench, Geekbench, and PassMark, while the GPU's average score of 38,135 derives from DirectX, OpenCL, Vulkan, and compute tests. The CPU's 84th percentile ranking among all CPUs means it outperforms roughly 84% of processors in the database, while the GPU's 81st percentile among all GPUs shows similar dominance in graphics compute.

In compute-heavy GPU workloads, the RTX 4080 Mobile achieves a Geekbench OpenCL score of 159,575 and a Vulkan score of 145,807. These figures indicate strong general-purpose compute capability, which is relevant for GPU-accelerated rendering or machine learning inference. The PassMark G3D score of 24,926 is the headline graphics figure, placing the GPU well above average. The PassMark GPU compute score of 11,191 shows that the card's non-graphics compute is solid but not its primary strength. DirectX 12 performance is particularly strong at 96 points in the PassMark DirectX 12 test, which is a good sign for modern game compatibility.

The CPU and GPU scores together suggest a balanced system where neither component drastically outclasses the other. The CPU's 84th percentile is only 3 points higher than the GPU's 81st percentile, meaning that in most workloads the two will scale together without one becoming a hard bottleneck. The nearest GPU rival, the NVIDIA GeForce MX570, is only 0.4% faster on average, which is a surprising comparison given the architectural gap; this likely reflects the mobile power constraints affecting the RTX 4080 Mobile's sustained clocks. The RTX 4080 Mobile also edges out the desktop RTX 4070 by 1.3%, showing that mobile flagship silicon can compete with lower-tier desktop cards in raw benchmark terms.

Upgrade Path and Platform

The platform is built around AMD Socket FP8, which is a mobile-only socket designed for thin-and-light laptops. The CPU supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s, and the memory bus is dual-channel, which is standard for this class. ECC memory is not supported, so error correction is not available for workstation-grade reliability. The CPU provides PCIe Gen 4 with 20 lanes, which is sufficient for the GPU and one or two NVMe SSDs, though the exact lane allocation depends on the laptop's design.

The GPU uses a PCIe 4.0 x16 bus interface, which is the full bandwidth available for a mobile discrete card. The GPU's TDP is 110 W, and the CPU's TDP is 28 W, for a combined thermal envelope of 138 W, not counting the rest of the system. The suggested PSU field is null, meaning no specific power supply recommendation is provided, but the low CPU TDP suggests that a typical high-end laptop power brick (around 180-240 W) would be ample. The GPU has no power connectors listed, as it is an IGP (integrated graphics package) soldered to the motherboard, so no user-accessible upgrade is possible.

For a sensible next upgrade, the data points to the memory and storage as the only user-serviceable components in most laptops. Upgrading to higher-capacity DDR5 modules would preserve the dual-channel bandwidth, while adding a PCIe Gen 4 NVMe drive would take advantage of the 20 CPU lanes. The CPU and GPU are both soldered and cannot be swapped, so the platform's longevity depends on the laptop's other components. The 28 W CPU TDP is low enough that cooling should not be a limiting factor for sustained loads, which is good for long rendering or compilation sessions.

Who Should Build It

This configuration targets users who need desktop-class performance in a portable form factor. The 84th percentile CPU and 81st percentile GPU mean that the system can handle tasks that would traditionally require a desktop tower. Content creators working with 4K video editing or complex 3D scenes will benefit from the CPU's multi-core scores, particularly the Cinebench R23 multi-core result of 13,082, which indicates strong rendering throughput. The GPU's 12 GB VRAM and 432.0 GB/s bandwidth provide ample headroom for high-resolution textures and complex shader workloads.

Software developers compiling large codebases will appreciate the 16 threads and high PassMark integer math score of 90,382, which correlates with compilation speed. Data scientists running local model training or inference can leverage the GPU's OpenCL score of 159,575 for matrix operations. Students in engineering or computer science programs will find the system capable of running CAD software, simulations, and virtual machines simultaneously, given the CPU's strong multi-threaded performance and the 28 W TDP that allows for all-day battery life in lighter tasks. Small business workstations that need to handle video conferencing, office suites, and occasional rendering will find this system overqualified, but the headroom ensures future software demands are met.

Balance and Bottleneck

The balance between CPU and GPU is close, with only a 3 percentage point difference in their respective percentiles. In CPU-bound workloads like code compilation or spreadsheet processing, the 8840HS will determine performance, and its 84th percentile ranking means it will rarely be the limiting factor in a laptop. In GPU-bound tasks like gaming at high resolutions or GPU rendering, the RTX 4080 Mobile will be the primary driver, and its 81st percentile suggests it can handle almost any game at high settings.

The data shows that in multi-threaded CPU tests, the 8840HS is essentially tied with the Ryzen 5 7645HX (0.0% delta), which means that adding more cores does not necessarily translate to better performance in this power class. This suggests that the 28 W TDP is the limiting factor for CPU scaling, not the architecture. For the GPU, the nearest rival comparison to the MX570 (0.4% delta) is counterintuitive, but it highlights that mobile GPU performance is heavily dependent on cooling and power delivery; the RTX 4080 Mobile's 110 W TDP is modest for its class, and sustained loads may see clock throttling.

In gaming, the balance will shift depending on resolution. At lower resolutions like 1080p, the CPU is more likely to be the bottleneck, especially in CPU-intensive titles, given that the 8840HS's single-core score of 1,737 in Cinebench R23 is decent but not exceptional. At higher resolutions like 4K, the GPU becomes the limiting factor, and the 12 GB VRAM may be a constraint for the most demanding textures. The lack of measured FPS data means these are estimates, but the benchmark scores suggest a system that is well-balanced for 1440p gaming, where both components are utilized effectively.

GPU Analysis

The NVIDIA GeForce RTX 4080 Mobile is built on the Ada Lovelace architecture, using the AD104 chip fabricated on TSMC's 5 nm process. The chip contains 35,800 million transistors on a 294 mm² die, giving it a transistor density of 121.8M per mm². The GPU has 7,424 shading units, 232 texture mapping units, and 80 raster output units, providing a raw compute throughput of 24.72 TFLOPS for both FP32 and FP16 (1:1) operations.
