# AMD Ryzen 7 7840HS + NVIDIA GeForce RTX 4090 Mobile

This pairing combines AMD's 8-core Zen 4 mobile processor with NVIDIA's flagship Ada Lovelace laptop GPU, creating a high-end laptop configuration that ranks in the 83rd percentile overall among all CPU+GPU combinations. The CPU sits at the 81st percentile against all CPUs, while the GPU holds the 84th percentile against all GPUs, indicating a well-matched pair where neither component dramatically outclasses the other. No measured FPS data exists for this exact combination in the FACT PACK, so all frame rate discussion below is estimated from the individual benchmark scores rather than direct game testing.

CPU Analysis

The AMD Ryzen 7 7840HS is a Phoenix-class processor built on TSMC's 4 nm process, packing 25,000 million transistors into a 178 mm² die. This 8-core, 16-thread chip operates with a base clock of 3.80 GHz and a boost clock of 5.10 GHz, all within a 35 W TDP envelope that makes it suitable for thin-and-light gaming laptops. The Zen 4 architecture brings significant instructions-per-clock improvements over previous generations, and the benchmark data reflects this efficiency.

Cache architecture consists of 64 KB L1 per core, 1 MB L2 per core, and 16 MB of shared L3 cache. This hierarchy supports the processor's multi-threaded throughput, as evidenced by the Cinebench R23 multicore score of 15,102 and Geekbench multicore score of 11,846. The 3DMark thread scaling tests show a clear progression from 1,904 at 2 threads to 7,316 at max threads, indicating that the processor continues to gain performance as more threads are utilized rather than hitting a memory bandwidth ceiling early.

Single-thread performance is respectable with a Geekbench single-core score of 2,031 and a Cinebench R23 single-core score of 1,761. The 3DMark single-thread score of 979 places this chip in a competitive position for lightly-threaded workloads like everyday application responsiveness and legacy game engines. The PassMark single-thread score of 3,753 reinforces this assessment.

The integrated Radeon 780M graphics provide a fallback display output, though in this pairing the discrete RTX 4090 Mobile handles all demanding graphics work. Memory support includes DDR5 with dual-channel configuration, delivering 89.6 GB/s of bandwidth, which is sufficient to feed the CPU's 8 cores without bottlenecking multi-threaded workloads. ECC memory support is present, which is unusual for a mobile consumer chip and suggests potential workstation applicability.

The average benchmark score of 29,955 places this CPU in a dead heat with the AMD Ryzen 7 8845HS (0% delta), which is essentially the same chip with a different model number. It edges out the AMD Ryzen 7 5800XT by 0.3% and the Ryzen 7 7840H by 0.3%, while leading the Ryzen 5 9600X by 0.8%. These narrow margins indicate that the 7840HS is performing at the top of its expected range, with differences well within run-to-run variance.

Benchmark Performance

The CPU's 3DMark results show strong scaling: 7,314 at 16 threads and 7,316 at max threads, confirming that all 16 threads are fully utilized without significant overhead. The 4-thread score of 3,651 represents approximately 50% of the max-thread score, which is expected for a processor where each core contributes equally. The 8-thread score of 6,092 demonstrates that the processor maintains efficiency even when half the threads are active.

Cinebench R15 results show 2,222.84 multicore and 274 single-core, while R23 results show 15,102 multicore and 1,761 single-core. The multicore-to-singlecore ratio in R23 is approximately 8.6:1, which is close to the theoretical 8:1 scaling expected from 8 full cores with simultaneous multithreading providing diminishing returns. PassMark tests reveal specific workload characteristics: integer math scores 98,682, floating point math scores 59,921, and extended instructions score 25,747, indicating strong SIMD and encryption throughput. Data encryption scores 20,627 while data compression scores 345,536, showing the processor handles both security workloads and compression tasks effectively.

The GPU delivers a Geekbench OpenCL score of 180,831 and Vulkan score of 170,774, placing it firmly in the high-end mobile graphics tier. The PassMark G3D score of 27,212 represents the directX gaming performance, while the GPU compute score of 12,347 shows compute-oriented workloads run at roughly 45% of the gaming performance level. DirectX 11 scores 262, DirectX 12 scores 107, and DirectX 9 scores 310, with DirectX 10 at 173 — these results suggest the GPU is optimized for modern APIs with the older DirectX 9 path showing relatively strong performance for legacy titles.

The GPU's average benchmark score of 43,667 places it just 0.8% above the NVIDIA Quadro M6000, 0.9% above the RTX 5050 Mobile, and 0.9% above the Quadro M6000 24 GB, while trailing the RTX A6000 by 0.9%. These comparisons position this mobile GPU within striking distance of professional workstation cards, which is notable for a laptop component. The combined CPU+GPU percentile of 83 indicates that this pairing outperforms roughly 83% of all recorded system configurations.

Balance and Bottleneck

The CPU's 81st percentile and GPU's 84th percentile are closely aligned, suggesting neither component will consistently bottleneck the other in most workloads. However, the specific benchmark deltas reveal subtle imbalances. The CPU's average score of 29,955 versus the GPU's 43,667 creates a performance envelope where the GPU has more headroom for graphics-intensive tasks than the CPU does for compute-heavy workloads.

In gaming scenarios, the RTX 4090 Mobile's raw graphics power — evidenced by its 32.98 TFLOPS FP32 performance and 576.0 GB/s memory bandwidth — will likely be the limiting factor only at lower resolutions where the CPU's single-thread performance of 979 in 3DMark becomes relevant. At higher resolutions, the GPU's pixel rate of 189.8 GPixel/s and texture rate of 515.3 GTexel/s will dominate, making the CPU's 8 cores sufficient to keep up.

For productivity workloads, the CPU's 35 W TDP and 16 MB L3 cache may constrain sustained multi-threaded performance compared to the GPU's compute capabilities. The PassMark GPU compute score of 12,347 versus the CPU's PassMark multithread score of 28,633 shows that for certain parallel workloads, the CPU can outperform the GPU despite the GPU's higher peak throughput — this suggests workload-dependent balance where some applications favor one component over the other.

The CPU's memory bandwidth of 89.6 GB/s is modest compared to the GPU's 576.0 GB/s, but these serve different functions. The CPU's dual-channel DDR5 bandwidth is sufficient for its 8 cores, while the GPU's 256-bit GDDR6 interface provides the high throughput needed for texture streaming and frame buffer operations. This separation means memory bandwidth is unlikely to create a cross-component bottleneck in typical usage.

Who Should Build It

This laptop configuration targets users who need flagship-level graphics performance without sacrificing CPU capability for everyday tasks. The 83rd combined percentile makes it suitable for gamers who want to play at high resolutions and maximum settings, as the GPU's 16 GB VRAM and 84th percentile ranking can handle demanding titles. Content creators working with video editing, 3D rendering, or large image processing will benefit from the GPU's compute capabilities and the CPU's multi-threaded scores.

Software developers compiling large codebases will appreciate the CPU's PassMark integer math score of 98,682 and multithread score of 28,633, which indicate strong compilation throughput. Students in engineering or computer science programs can leverage the ECC memory support and the combination of CPU and GPU compute for simulation and data analysis coursework. Small business workstations that occasionally need to render presentations or process large datasets will find this pairing capable, though the 35 W CPU TDP suggests it is optimized for bursty workloads rather than sustained all-core operation.

The 4 nm CPU manufacturing process and 5 nm GPU process indicate a modern, power-efficient platform that balances performance with battery life considerations for laptop use. The integrated Radeon 780M provides a backup graphics solution that can extend battery life when the discrete GPU is not needed.
