The AMD Ryzen 7 8745HX and NVIDIA GeForce RTX 4080 Mobile form a high-end laptop pairing that delivers top-tier performance across both CPU- and GPU-intensive tasks. With a combined percentile of 87, this configuration sits firmly in the upper echelon of mobile computing hardware, indicating that the vast majority of systems on the market will trail it in overall capability. The data shows a balanced partnership: the Ryzen 7 8745HX posts a multithread score of 31517 and a single-thread score of 3879, while the RTX 4080 Mobile achieves a Passmark G3D score of 24926 and a Geekbench OpenCL score of 159575. No measured FPS rows exist for this exact combination — the FACT PACK contains no measuredFps data — so all frame rate expectations below are estimates derived from these benchmark scores, not direct measurements.

Balance and Bottleneck

The balance between the Ryzen 7 8745HX and the RTX 4080 Mobile is remarkably even, with neither component dramatically overshadowing the other in the workload profiles captured by the benchmark data. The CPU’s percentile of 92 against all CPUs and the GPU’s percentile of 81 against all GPUs indicate that the processor is slightly more dominant in its respective field, but the gap is not so wide that the GPU becomes the limiting factor in most scenarios. For gaming at high resolutions, the GPU’s raw compute power — 24.72 TFLOPS FP32 and a pixel rate of 133.2 GPixel/s — will typically be the primary driver of frame rates, especially as resolution scales up and the rendering load shifts toward the graphics card.

In CPU-bound workloads, the Ryzen 7 8745HX shows its strength through a multithread score of 31517 and a physics score of 1681. The physics score, which often correlates with gaming performance in titles that simulate rigid bodies or complex environments, is notably strong and suggests that the CPU can keep up with the GPU’s output without introducing a significant bottleneck. However, the Passmark find prime numbers score of 159 is relatively low, indicating that the CPU may lag in highly serial, integer-heavy tasks that do not scale with thread count — a potential bottleneck in older games or single-threaded simulation code.

The FPS scaling story, based on estimated performance, points to a system where the GPU is the limiting factor at 4K or with ray tracing enabled, while at 1080p the CPU’s single-thread performance (3879) becomes more relevant. The RTX 4080 Mobile’s memory bandwidth of 432.0 GB/s and 12 GB of GDDR6 VRAM are sufficient to feed the GPU at most settings, but in scenes with heavy texture streaming or large open worlds, the 192-bit memory bus could create a minor constraint. The CPU’s memory bandwidth of 83.2 GB/s, paired with dual-channel DDR5 support, is adequate for feeding the 8 cores and 16 threads, but it is not a standout figure compared to the GPU’s bandwidth, reinforcing that the GPU is the more memory-hungry component.

The data also reveals that the CPU’s integrated graphics, the Radeon 610M, are present but not a factor in this pairing; the discrete RTX 4080 Mobile handles all rendering, so the iGPU’s performance is irrelevant except for power-saving scenarios. Overall, the bottleneck profile is workload-dependent: productivity and multithreaded tasks will see the CPU approaching its limits, while gaming at high resolutions will be GPU-bound, with the CPU providing ample headroom in most cases.

Gaming Performance

Since no measured FPS rows exist for this exact combination, the following frame rate expectations are estimates derived from the benchmark scores, not direct measurements. The RTX 4080 Mobile’s Passmark G3D score of 24926 and DirectX 12 score of 96 suggest that this GPU is capable of high-refresh-rate gaming at 1080p and 1440p in most titles, with 4K gaming possible at reduced settings or with upscaling technologies. The DirectX 11 score of 244 is notably higher than the DirectX 12 score, which is unusual and may indicate that older APIs run particularly well on this hardware, though modern titles that rely on DirectX 12 Ultimate features (supported per the API list) will still perform strongly.

At 1080p, the combination of the Ryzen 7 8745HX’s single-thread score of 3879 and the GPU’s 24.72 TFLOPS FP32 should deliver frame rates well above 60 FPS in most esports titles and competitive shooters, with the CPU rarely becoming a limiting factor. The physics score of 1681 supports this, as it indicates strong performance in games that use CPU-driven physics. At 1440p, the GPU becomes the primary driver, and the 12 GB VRAM provides enough capacity for high-detail textures in most current releases, though some titles with ultra texture packs may approach the limit.

At 4K, the estimated performance drops to 30–60 FPS depending on the game and settings, with the GPU’s pixel rate of 133.2 GPixel/s and texture rate of 386.3 GTexel/s being the key metrics. The Geekbench Vulkan score of 145807 suggests that Vulkan-based titles, such as many modern AAA games, will see efficient utilization of the GPU’s architecture. The RTX 4080 Mobile’s 58 RT cores and 232 tensor cores indicate that ray tracing and DLSS features are supported, which can extend playable frame rates in heavy titles, but the lack of measured data means these are qualitative expectations rather than verified figures.

For users prioritizing high refresh rates, the data suggests that 1080p and 1440p are the sweet spots for this pairing, with 4K requiring compromises on settings to maintain smooth gameplay. The GPU’s Passmark G2D score of 929 is low, but this metric is irrelevant for gaming and only affects 2D desktop workloads. Overall, the estimated gaming performance is strong across all resolutions, with the caveat that 4K ultra settings will be demanding on the 12 GB VRAM and 192-bit bus width.

CPU Analysis

The AMD Ryzen 7 8745HX is an 8-core, 16-thread processor based on the Zen 4 architecture, built on a 5 nm process at TSMC with 6,570 million transistors. The base clock of 3.60 GHz and boost clock of 5.10 GHz are respectable for a mobile chip, and the 55 W TDP indicates a power envelope that allows for sustained performance in a laptop chassis. The CPU’s cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache, which is adequate for gaming and productivity but not the largest on the market.

Benchmark results show a mixed profile. The Passmark multithread score of 31517 places the CPU at the 92nd percentile against all CPUs, meaning it outperforms 92% of processors in the database. The nearest rival, the AMD Ryzen 9 7945HX, has an average score of 60099, which is essentially identical (deltaPct of 0), indicating that the 8745HX is on par with a higher-tier mobile chip in overall benchmark averages. The Intel Core i9-14900F is also closely matched with a deltaPct of 0.2, while the AMD Ryzen 9 7945HX3D trails by 0.8. This suggests that the 8745HX is a high-end mobile processor, but not the absolute fastest, and that its performance is consistent with other flagship CPUs.

In single-threaded tasks, the Passmark single-thread score of 3879 is strong, though not class-leading. The floating point math score of 61972 and integer math score of 100328 indicate robust throughput for scientific and financial workloads, while the extended instructions score of 27638 suggests that AVX and related instruction sets are well-supported. The data compression score of 363759 is exceptionally high, making this CPU well-suited for file compression and archival tasks, while the data encryption score of 21840 is moderate, indicating adequate but not exceptional cryptography performance.

The random string sorting score of 44494 is another strong result, pointing to good performance in database and sorting workloads. For real-world use, this CPU will handle software compilation, video encoding, and multitasking with ease, and its 16 threads allow for efficient parallel processing. The lack of ECC memory support and the dual-channel DDR5 memory bus (83.2 GB/s bandwidth) are minor limitations for server-like workloads but are standard for mobile gaming and content creation laptops. The CPU is unlocked, which is unusual for a mobile part, but overclocking headroom is limited by the thermal constraints of a laptop chassis.

GPU Analysis

The NVIDIA GeForce RTX 4080 Mobile is a high-end laptop GPU based on the Ada Lovelace architecture, built on a 5 nm process at TSMC with 35,800 million transistors on a 294 mm² die. The GPU features 7424 shading units, 232 TMUs, and 80 ROPs, with 58 RT cores and 232 tensor cores for ray tracing and AI acceleration. The base clock is 1290 MHz with a boost clock of 1665 MHz, and the memory runs at 2250 MHz (18 Gbps effective), providing 432.0 GB/s of bandwidth across a 192-bit bus with 12 GB of GDDR6 memory.

The benchmark scores for the GPU are strong. The Passmark G3D score of 24926 is a solid indicator of overall 3D rendering performance, while the DirectX 11 score of 244 and DirectX 12 score of 96 show good API utilization. The Geekbench OpenCL score of 159575 and Vulkan score of 145807 highlight strong compute and cross-platform graphics performance. The GPU’s FP32 output of 24.72 TFLOPS and FP16 output of 24.72 TFLOPS (1:1) are impressive for a mobile part, and the texture rate of 386.3 GTexel/s and pixel rate of 133.2 GPixel/s support high-resolution rendering.

For rendering workloads, the 12 GB of VRAM is sufficient for most 3D scenes, but large textures or complex scenes may approach the capacity limit. The 192-bit memory bus is narrower than some desktop counterparts, but the high bandwidth compensates. The RT cores and tensor cores enable hardware-accelerated ray tracing and DLSS, which can significantly boost frame rates in supported games and render times in creative applications. The GPU’s 81st percentile rank against all GPUs indicates that it is better than 81% of GPUs in the database, though the nearest rivals show that the RTX 5080 Mobile is slightly ahead by 0.6%, and the desktop RTX 4070 is 1.3% behind.

The GPU’s TDP of 110 W is typical for a high-performance mobile part, and the absence of power connectors (slot width: IGP) suggests it is soldered to the motherboard, drawing power through the laptop’s power delivery system. The bus interface is PCIe 4.0 x16, which is adequate for this GPU’s performance level. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, ensuring compatibility with current and near-future software.

Upgrade Path and Platform

The AMD Ryzen 7 8745HX uses the AMD Socket FL1, which is specific to laptop platforms, so upgrading the CPU in the future is not a practical option for most users; the CPU is soldered or otherwise non-replaceable in typical laptop designs. The memory support is DDR5 with a dual-channel bus, providing 83.2 GB/s of bandwidth, and users can potentially upgrade RAM if the laptop has accessible SODIMM slots, though many high-end laptops use soldered memory. The CPU supports PCIe Gen 5 with 28 lanes (CPU only), while the GPU uses PCIe 4.0 x16, so the platform has headroom for future high-bandwidth peripherals.

The GPU has no suggested PSU (suggestedPsu: null) and a TDP of 110 W, which is modest for a high-end mobile GPU. Since this is a laptop, the PSU is an external AC adapter, and the system’s total power draw will be the sum of the CPU (55 W TDP), GPU (110 W TDP), and other components, typically requiring a 200–300 W adapter, though the FACT PACK does not provide a specific figure. The lack of power connectors on the GPU indicates that power is delivered through the motherboard, and users should not expect to upgrade the GPU in a laptop.

A sensible next upgrade for this platform would be to increase memory capacity or speed, if the laptop supports it, or to add a high-speed NVMe SSD using the PCIe Gen 5 lanes. For external connectivity, the PCIe Gen 5 support allows for future eGPU enclosures, though the laptop’s Thunderbolt or USB4 ports (not specified in the FACT PACK) would be the practical interface. Given the CPU’s 92nd percentile and GPU’s 81st percentile, the platform is already near the top of the mobile performance range, so upgrades are more about capacity (RAM, storage) than raw performance.
