# AMD Ryzen 5 8645HS + NVIDIA GeForce RTX 4080 Mobile

This laptop pairing combines AMD's 6-core Zen 4 Hawk Point processor with NVIDIA's Ada Lovelace-based RTX 4080 Mobile GPU, landing at the 82nd percentile overall among all benchmarked CPU+GPU combinations. The data set contains no measured FPS rows for this exact pairing, so all frame-rate discussion below is estimated from the individual CPU and GPU benchmark scores rather than direct game testing.

GPU Analysis — VRAM, bandwidth, clocks, RT/tensor hardware, what the benchmark scores mean for rendering

The NVIDIA GeForce RTX 4080 Mobile is built on the AD104 chip using TSMC's 5 nm process, packing 35,800 million transistors across a 294 mm² die. The GPU runs at a base clock of 1290 MHz and boosts to 1665 MHz, with memory clocked at 2250 MHz (18 Gbps effective). It carries 12 GB of GDDR6 memory on a 192-bit bus, yielding 432.0 GB/s of bandwidth — a substantial pool for high-resolution textures and ray-traced assets in a mobile form factor.

The GPU's compute configuration is robust for a laptop part: 7424 shading units, 232 texture mapping units, and 80 raster output pipelines. Ray tracing hardware is present in the form of 58 RT cores, while 232 tensor cores handle AI-accelerated workloads such as DLSS frame generation and denoising. Pixel rate reaches 133.2 GPixel/s and texture rate hits 386.3 GTexel/s, which translates to solid fill-rate headroom for 1440p and 4K rendering scenarios. FP32 compute is rated at 24.72 TFLOPS, with FP16 at the same 24.72 TFLOPS (1:1 ratio), indicating that the GPU does not trade away half-precision performance for double-rate throughput.

Benchmark data shows the GPU achieving a Passmark G3D score of 24926, placing it at the 81st percentile among all GPUs. The Geekbench OpenCL score of 159575 and Vulkan score of 145807 further confirm strong compute and graphics API performance. In DirectX tests, the GPU scores 157 in DX10, 244 in DX11, and 96 in DX12, while DirectX 9 yields 286; these scores reflect the GPU's ability to handle both legacy and modern graphics APIs, though the DX12 score of 96 appears modest relative to the G3D result, suggesting driver or benchmark-specific variance. Passmark GPU compute score of 11191 and G2D score of 929 round out the picture, with the G2D figure indicating decent 2D acceleration for desktop and productivity tasks.

The nearest rivals provide context: the RTX 4080 Mobile's average benchmark score of 38135 is essentially tied with the NVIDIA GeForce MX570 (38299, -0.4% delta) and the RTX 5080 Mobile (38349, -0.6% delta), while it sits 1.3% ahead of both the RTX 4070 and Tesla P4. This clustering suggests that the RTX 4080 Mobile occupies a high-end tier where small percentage differences separate adjacent SKUs. For rendering workloads, the combination of 12 GB VRAM, 432 GB/s bandwidth, and 58 RT cores means the GPU can handle ray-traced scenes at high settings in most current titles, though the 192-bit bus may limit extreme resolutions or heavy texture streaming compared to wider-memory parts.

Benchmark Performance — exact CPU and GPU scores, percentile positions, and what the combined picture is

The AMD Ryzen 5 8645HS delivers a Cinebench R23 multicore score of 13220 and single-core score of 1714, while the older R15 test shows 2094 multicore and 270 single-core. Passmark results for the CPU include a single-thread score of 3653, multithread score of 22586, and integer math at 72640, with floating-point math at 44833. The CPU's average benchmark score is 33244, placing it at the 83rd percentile among all CPUs — a strong showing for a 6-core mobile part.

The GPU's Passmark G3D score of 24926 and average benchmark score of 38135 put it at the 81st percentile among all GPUs. Combined, this CPU+GPU pair reaches the 82nd percentile overall, indicating that neither component dramatically outclasses the other in aggregate terms. The GPU's average score of 38135 exceeds the CPU's 33244 by roughly 14.7%, suggesting that the graphics card is the stronger component in raw benchmark terms, but the CPU's 83rd percentile rank versus the GPU's 81st shows they are closely matched in relative standing among their respective peers.

Looking at rival comparisons, the Ryzen 5 8645HS trades blows with several notable processors: it is 0.1% ahead of the Intel Core i7-14701E (33206) and AMD Ryzen 9 PRO 6950H (33201), 0.4% behind the Intel Core i5-12600HX (33375), and 0.5% ahead of the AMD Ryzen 7 7745HX (33091). These sub-1% deltas indicate that the 8645HS sits in a highly competitive mid-to-high-end CPU tier where benchmark differences are within noise. On the GPU side, the RTX 4080 Mobile's nearest rivals — MX570, RTX 5080 Mobile, RTX 4070, and Tesla P4 — are all within 1.3% of its average score, reinforcing that the mobile GPU landscape is tightly packed at this performance level.

In practical terms, the combined picture shows a laptop capable of high-refresh 1080p gaming and solid 1440p performance, with the GPU likely being the primary driver for frame rates in graphics-intensive titles. The CPU's single-core score of 1714 in R23 and 3653 in Passmark single-thread suggest it can feed the GPU adequately in most scenarios, though the six-core configuration may become a limiting factor in heavily multithreaded games or background workloads.

CPU Analysis — cores, clocks, architecture, what the benchmark scores mean for real workloads

The AMD Ryzen 5 8645HS is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Hawk Point, and manufactured on TSMC's 4 nm process. The chip integrates 25,000 million transistors on a 178 mm² die, with a base clock of 4.30 GHz and boost clock of 5.00 GHz. The TDP is rated at 45 W, making it a mainstream mobile part suited for thin-and-light gaming laptops and productivity machines. Cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3, which is adequate for a 6-core design but smaller than some higher-end desktop or HX-series parts.

Memory support is limited to DDR5 with a dual-channel bus, providing 89.6 GB/s of bandwidth. The CPU offers PCIe Gen 4 with 20 lanes (CPU only), which is sufficient for a discrete GPU and one or two NVMe drives. Integrated graphics come in the form of the Radeon 760M, which provides a fallback for display output and light workloads when the discrete GPU is idle. ECC memory is not supported, and the multiplier is locked, so overclocking is not an option. The CPU uses the AMD Socket FP8, with part numbers covering FP7 and FP7r2 variants as well.

Benchmark results paint a clear picture of the CPU's capabilities. The Cinebench R23 multicore score of 13220 is strong for a 6-core mobile chip, indicating that it can handle multithreaded productivity tasks like video encoding, 3D rendering, and software compilation with reasonable efficiency. The single-core score of 1714 is equally impressive, reflecting Zen 4's high IPC and the 5.00 GHz boost clock. Passmark data compression score of 265483 and data encryption score of 15588 show solid performance in data-intensive workloads, while extended instructions score of 20003 and find prime numbers score of 75 (a low absolute number due to the benchmark's scaling) indicate competent integer and SIMD processing.

For real workloads, the CPU's 83rd percentile rank means it outperforms roughly 83% of all CPUs in the database. The nearest rival comparisons — all within 0.5% of its average score — suggest that users will see virtually identical performance to the Intel Core i7-14701E, AMD Ryzen 9 PRO 6950H, Intel Core i5-12600HX, and AMD Ryzen 7 7745HX in mixed workloads. The Passmark multithread score of 22586 and single-thread score of 3653 indicate that the CPU handles both lightly threaded tasks (like web browsing, office apps, and legacy games) and heavily threaded tasks (like video rendering and batch processing) competently. The floating-point math score of 44833 and integer math score of 72640 further confirm strong arithmetic throughput for scientific and engineering applications.

Who Should Build It — target users and industries (gamers at specific resolutions, content creators, developers, students, small business workstations) tied strictly to the measured performance

This laptop pairing targets users who need high-end gaming and productivity in a portable form factor. The GPU's Passmark G3D score of 24926 and 81st percentile rank suggest it can handle modern games at 1080p and 1440p with high settings, though the lack of measured FPS data means exact settings and resolutions should be inferred cautiously. The 12 GB VRAM and 432 GB/s bandwidth make it suitable for texture-heavy titles and ray-traced games, where the 58 RT cores can accelerate lighting and reflection effects.

Content creators will benefit from the GPU's 24.72 TFLOPS FP32 compute and 232 tensor cores, which accelerate CUDA-accelerated effects in video editing software and GPU rendering in 3D applications. The CPU's Cinebench R23 multicore score of 13220 and Passmark multithread score of 22586 support smooth timeline scrubbing and faster export times in video editing suites. For 3D rendering, the GPU's compute performance and VRAM capacity allow for moderate scene complexity, though the 192-bit bus may limit extreme texture loads.

Software developers will find the CPU's 6 cores and 12 threads adequate for compilation tasks, with the single-core score of 1714 in R23 indicating fast iteration for builds that are not fully parallelized. The 16 MB L3 cache and 89.6 GB/s memory bandwidth help with large codebases and virtual machines. Students and small business workstations that need a balance of performance and portability will appreciate the 45 W TDP CPU and the GPU's ability to accelerate spreadsheet, database, and visualization workloads, though the discrete GPU is overkill for basic office tasks. The Passmark G2D score of 929 suggests the GPU handles 2D acceleration well, which benefits desktop responsiveness in multi-monitor setups.

Balance and Bottleneck — which component limits which workload, using percentiles and FPS scaling as evidence

The data shows a near-balanced pairing, with the CPU at the 83rd percentile and GPU at the 81st percentile among their respective categories, and the combined build at the 82nd percentile. In graphics-bound workloads, the GPU's average score of 38135 versus the CPU's 33244 indicates that the GPU is the stronger absolute performer, so frame rates in most games will scale primarily with GPU capability. The GPU's 81st percentile rank means it is slightly below the CPU's 83rd percentile in relative standing, suggesting that in some CPU-light, GPU-heavy titles, the GPU could be the first to saturate.

However, the CPU's 6-core, 12-thread configuration may become a bottleneck in games that leverage more than 6 cores or in scenarios where high frame rates demand significant per-thread performance. The single-core score of 1714 in R23 is strong, but it is not at the very top tier; the nearest rival comparisons show the CPU is within 0.5% of several HX and desktop-derived parts, so it is not a weak link. For resolution scaling, the GPU's 12 GB VRAM and 432 GB/s bandwidth support 1080p and 1440p gaming without obvious memory constraints, but at 4K, the 192-bit bus might limit bandwidth-sensitive scenarios.

For productivity workloads, the CPU's 6 cores are a potential limit in heavily multithreaded tasks like 3D rendering or video encoding, where 8-core or 16-core parts would scale better. The Passmark multithread score of 22586 is respectable but not class-leading, and the Cinebench R23 multicore score of 13220 places it below many desktop 8-core parts. Conversely, the GPU's compute performance and tensor cores can offload some rendering tasks, mitigating CPU bottlenecks in GPU-accelerated renderers. Overall, the bottleneck shifts between CPU and GPU depending on the workload: games and GPU compute favor the GPU, while CPU-bound simulations, physics, and lightly threaded tasks may see the processor as the limiting factor.

Usage Scenarios — grounded in the scores: high-refresh gaming, streaming, video editing, 3D rendering, software development, student and office work. One short paragraph per scenario, citing the numbers that support the verdict

High-refresh gaming: The GPU's Passmark G3D score of 24926 and 81st percentile rank indicate it can drive high-refresh 1080p monitors and solid 1440p displays, though without measured FPS data, exact frame rates are estimates. The CPU's single-core score of 1714 in R23 ensures that it will not hold back the GPU in most titles, and the GPU's 12 GB VRAM and 432 GB/s bandwidth provide sufficient headroom for high-texture settings at these resolutions.

Streaming: The GPU's 232 tensor cores and 24.72 TFLOPS FP32 compute can handle NVENC encoding and AI-enhanced streaming features without significantly impacting gaming performance. The CPU's 6 cores and 12 threads, with a Passmark multithread score of 22586, are adequate for encoding and running streaming software simultaneously, though heavy multitasking may strain the 45 W TDP part.

Video editing: The GPU's 24.72 TFLOPS and 12 GB VRAM accelerate effects, color grading, and preview rendering in CUDA-accelerated editors, while the CPU's Cinebench R23 multicore score of 13220 supports faster export times. The 89.6 GB/s memory bandwidth helps with multi-track timelines and 4K footage, though the 6-core CPU may limit scrub responsiveness in very complex projects.

3D rendering: The GPU's compute performance and 58 RT cores enable GPU-accelerated rendering with ray tracing in applications like Blender and Octane, with 12 GB VRAM handling moderate scenes. The CPU's Passmark floating-point math score of 44833 and integer math score of 72640 support CPU-based rendering, but the 6-core configuration will be slower than higher-core alternatives.

Software development: The CPU's single-core score of 1714 in R23 and Passmark single-thread score of 3653 provide fast compilation for incremental builds, while the 16 MB L3 cache and 12 threads handle parallel builds. The GPU is largely irrelevant for most development tasks, but its compute capability can accelerate machine learning workloads or local testing of CUDA code.

Student and office work: The CPU's 83rd percentile rank ensures smooth multitasking across office suites, browsers, and communication tools, with the Passmark G2D score of 929 indicating responsive 2D performance. The discrete GPU is overkill for this scenario, but it provides headroom for future needs or occasional gaming and creative work.

Upgrade Path and Platform — socket, memory support, PCIe, PSU headroom from suggestedPsu/tdp, what a sensible next upgrade looks like

The CPU uses the AMD Socket FP8, which is specific to mobile platforms, so upgrading the processor in a laptop is generally not feasible; the socket is soldered in most designs. Memory support is limited to DDR5 with a dual-channel bus, and the 89.6 GB/s bandwidth is fixed by the platform. The CPU provides PCIe Gen 4 with 20 lanes (CPU only), while the GPU uses a PCIe 4.0 x16 interface, so storage and expansion are limited to Gen 4 devices — there is no Gen 5 support on this platform.

The GPU has a TDP of 110 W and no power connectors (it draws power through the motherboard), and no suggested PSU is listed since this is a laptop component. The CPU's TDP is 45 W, so the total system power draw is modest for a high-end laptop, typically requiring a 180 W or higher AC adapter, though the FACT PACK does not specify the adapter wattage. The GPU's slot width is listed as "IGP," meaning it is integrated into the motherboard package, so there is no user-replaceable GPU in most implementations.

A sensible next upgrade for this platform would be adding more DDR5 memory, as the dual-channel bus benefits from populated slots, though the FACT PACK does not specify maximum capacity. Storage upgrades are possible via PCIe Gen 4 NVMe drives, which are supported by the 20 CPU lanes. The CPU's lock multiplier and mobile socket preclude processor swaps, and the GPU is not upgradeable, so this platform is essentially fixed at purchase. Users seeking more performance would need to move to a different laptop with a higher-tier CPU (e.g., 8-core or 16-core parts) or a newer GPU generation, such as the RTX 5080 Mobile, which benchmarks within 0.6% of the RTX 4080 Mobile in this data.

Build Overview — what this CPU+GPU pairing is, its class (desktop/laptop from buildClass), and overall tier from the percentiles

This pairing is a laptop build, as indicated by the buildClass field, combining the AMD Ryzen 5 8645HS mobile CPU with the NVIDIA GeForce RTX 4080 Mobile GPU. The CPU is a 6-core, 12-thread Zen 4 part with a 45 W TDP, while the GPU is an Ada Lovelace-based mobile graphics solution with a 110 W TDP. Together, they form a high-end mobile platform aimed at gaming and content creation, with the combined percentile ranking of 82 indicating that this pairing outperforms 82% of all benchmarked CPU+GPU combinations.

Individually, the CPU sits at the 83rd percentile among all CPUs, and the GPU at the 81st percentile among all GPUs, showing that the two components are closely matched in relative performance. The CPU's average benchmark score of 33244 and the GPU's average score of 38135 confirm that the GPU contributes slightly more to the overall performance envelope. This is a premium laptop configuration for users who prioritize gaming and GPU-accelerated workloads, though the 6-core CPU may limit the most demanding multithreaded tasks. The lack of measured FPS data means exact gaming performance is estimated from benchmark scores, but the underlying hardware specifications and percentile rankings indicate a capable high-refresh 1080p and solid 1440p gaming machine.
