# 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 Ada Lovelace architecture, fabricated on a 5 nm process at TSMC with 35,800 million transistors on a 294 mm² die. The chip, designated AD104, carries 12 GB of GDDR6 memory across a 192-bit bus, yielding 432.0 GB/s of memory bandwidth. Memory clocks run at 2250 MHz with 18 Gbps effective data rate. The GPU operates at a base clock of 1290 MHz and a boost clock of 1665 MHz, with a TDP of 110 W.

The compute configuration is substantial: 7424 shading units, 232 texture mapping units, and 80 raster operation processors. Ray tracing hardware includes 58 RT cores, while 232 tensor cores handle AI-accelerated workloads. The pixel rate is 133.2 GPixel/s, and the texture rate is 386.3 GTexel/s. Floating-point throughput reaches 24.72 TFLOPS for both FP32 and FP16 (1:1 ratio), which indicates balanced compute capability for both traditional graphics and mixed-precision workloads.

Benchmark results place this GPU firmly in the upper tier of mobile graphics. In Geekbench OpenCL, the score is 159575, while Vulkan performance registers 145807. The PassMark G3D score is 24926, and GPU compute (PassMark) is 11191. DirectX 11 and DirectX 12 scores are 244 and 96 respectively, while DirectX 10 scores 157 and DirectX 9 scores 286. The 2D graphics score is 929. The GPU sits at the 81st percentile among all GPUs, with an average benchmark score of 38135.

For rendering workloads, the data suggests strong capabilities. The 24.72 TFLOPS FP32 throughput means raw shader compute is high, which translates to faster polygon processing and pixel shading in real-time engines. The 58 RT cores provide dedicated hardware for ray-traced effects, and the 232 tensor cores enable DLSS-style upscaling and AI denoising. The 12 GB VRAM capacity is sufficient for high-resolution textures and complex scenes, while the 432.0 GB/s bandwidth ensures data can feed the 7424 shading units without becoming a bottleneck in most scenarios.

The nearest rival comparisons show the RTX 4080 Mobile sits within a tight performance cluster. It is 0.4% behind the NVIDIA GeForce MX570 (which scores 38299), 0.6% behind the RTX 5080 Mobile (38349), and 1.3% ahead of both the RTX 4070 (37648) and Tesla P4 (37628). The small deltas indicate that the RTX 4080 Mobile occupies a specific performance band where minor architectural differences determine ranking order.

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

The CPU benchmarks for the AMD Ryzen 5 8640HS show a consistent pattern across multiple test suites. In Cinebench R23, the multi-core score is 11486 and single-core is 1711. Cinebench R15 produces 1845 multi-core and 268 single-core. Geekbench results are 7461 multi-core and 1778 single-core. PassMark tests include multi-thread at 19889, single-thread at 3584, integer math at 68173, floating-point math at 39725, extended instructions at 15855, data compression at 226544, data encryption at 13551, physics at 970, random string sorting at 27316, and find prime numbers at 70.

The CPU's average benchmark score is 26106, placing it at the 78th percentile among all CPUs. The nearest rivals show close competition: the AMD Ryzen 5 8540U scores 26187 (0.3% ahead), the Intel Core i9-11900KF scores 26212 (0.4% ahead), the Intel Core i7-14701TE scores 26013 (0.4% behind), and the AMD Ryzen AI 5 340 scores 25981 (0.5% behind). These tiny margins suggest the 8640HS sits at a performance equilibrium point where no single rival dominates by more than half a percent.

The GPU, as noted, holds an 81st percentile position with an average score of 38135. The combined percentile for this CPU+GPU pairing is 80, indicating that the system as a whole is positioned slightly below the GPU's individual standing but above the CPU's. The combined picture shows a laptop configuration where the GPU is the stronger component relative to its peer group, while the CPU is competent but not class-leading.

The data shows no measured FPS results for this exact combination — the FACT PACK contains no measuredFps data. All frame-rate discussion must therefore be treated as estimated from the benchmark scores. The CPU's multi-threaded performance (11486 in Cinebench R23, 19889 in PassMark multi-thread) is adequate to feed the GPU in most scenarios, though the disparity in percentiles (78 vs 81) suggests the GPU may be held back in CPU-limited workloads.

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

The AMD Ryzen 5 8640HS is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Hawk Point. It belongs to the 8000 series and is built on TSMC's 4 nm process with 25,000 million transistors on a 178 mm² die. The base clock is 3.50 GHz with a boost clock of 4.90 GHz, and the TDP is 28 W. The CPU uses the AMD Socket FP8 and supports DDR5 memory in dual-channel configuration, providing 89.6 GB/s of memory bandwidth. PCIe support is Gen 4 with 20 lanes from the CPU. Integrated graphics are provided by the Radeon 760M. The processor is not multiplier-unlocked and was released on 2023-12-05.

The cache hierarchy is structured as 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. This amounts to 6 MB of L2 total and 16 MB of L3, which is modest for modern workloads but consistent with a 28 W mobile processor. ECC memory is not supported.

Benchmark scores reveal the CPU's strengths and limitations. The single-core Cinebench R23 score of 1711 indicates strong per-thread performance, which is critical for lightly-threaded applications like web browsing, office suites, and legacy software. The Geekbench single-core score of 1778 corroborates this. The multi-core scores — 11486 in Cinebench R23 and 7461 in Geekbench — show that the 6-core/12-thread configuration scales reasonably well, though it cannot match higher-core-count desktop parts.

PassMark results provide granular insights into specific workload types. Integer math scores 68173, floating-point math scores 39725, and extended instructions score 15855. Data compression is particularly strong at 226544, while data encryption scores 13551. The physics score of 970 and find prime numbers score of 70 are lower, reflecting the processor's mobile power envelope. Random string sorting scores 27316.

The 78th percentile ranking places this CPU above the majority of all processors in the database. The nearest rival comparisons — all within 0.5% — suggest that at this performance tier, architectural differences between Zen 4, Raptor Lake, and Alder Lake derivatives are negligible in aggregate benchmarks. The 4.90 GHz boost clock is notably high for a 28 W part, which helps explain the competitive single-thread scores.

For real workloads, the data indicates the 8640HS handles productivity tasks, code compilation, and moderate multi-threaded rendering without issue. The 16 MB L3 cache is sufficient for most applications, and the 89.6 GB/s memory bandwidth supports the CPU's compute demands. The integrated Radeon 760M provides a fallback for display output and light graphics work when the discrete GPU is not engaged.

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

The balance between the Ryzen 5 8640HS and the RTX 4080 Mobile is skewed toward the GPU. The CPU's 78th percentile and the GPU's 81st percentile, combined with the system's 80th percentile overall, indicate that the GPU is the stronger component relative to peers. In GPU-bound workloads — typically high-resolution gaming, ray tracing, and 3D rendering — the RTX 4080 Mobile will operate near its full potential, with the CPU providing adequate feeding. The 24.72 TFLOPS FP32 throughput and 432.0 GB/s bandwidth are the limiting factors for frame rates in these scenarios.

In CPU-bound workloads — such as physics simulation, data compression, and single-threaded applications — the 8640HS becomes the constraint. The PassMark physics score of 970 and find prime numbers score of 70 are modest, suggesting that compute-heavy single-threaded tasks will not fully utilize the GPU's capabilities. The Cinebench R23 multi-core score of 11486 is respectable but not exceptional; heavily multi-threaded CPU workloads like video encoding may cause the GPU to wait on data.

The FPS scaling evidence, while estimated, points to a similar conclusion. At 1080p with lower graphics settings, the CPU's 1711 single-core Cinebench R23 score may limit frame rates in esports titles that rely on high CPU throughput. At 1440p and 4K with ultra settings, the GPU's 12 GB VRAM and 432.0 GB/s bandwidth become the determining factors, and the 81st percentile GPU ranking suggests it will hold up well.

The memory configuration also affects balance. The CPU's 89.6 GB/s DDR5 bandwidth is significantly lower than the GPU's 432.0 GB/s, which is expected given the different roles. However, in mixed workloads that stress both components — such as gaming while streaming — the CPU's 12 threads may be saturated, causing frame drops. The 28 W TDP of the CPU versus the 110 W TDP of the GPU also indicates that the GPU draws nearly four times the power, which is typical for a laptop with a discrete graphics solution.

# Who Should Build It — target users and industries tied strictly to the measured performance

This laptop configuration targets users who need strong GPU performance with a competent CPU in a mobile form factor. The 81st percentile GPU ranking makes it suitable for gamers at 1440p and 4K resolutions, where the 12 GB VRAM and 432.0 GB/s bandwidth can handle high-resolution textures and modern game engines. The 58 RT cores enable ray-traced lighting and reflections, which are increasingly common in AAA titles.

Content creators working with video editing and 3D rendering will benefit from the GPU's 24.72 TFLOPS FP32 throughput and 232 tensor cores for AI-accelerated effects. The CPU's 6 cores and 12 threads, with a Cinebench R23 multi-core score of 11486, can handle timeline scrubbing and preview rendering, though final exports will rely more on the GPU. The PassMark data compression score of 226544 suggests strong performance for file archiving and data-heavy workflows.

Software developers will find the CPU's 78th percentile ranking adequate for compilation and testing. The 4.90 GHz boost clock and 1711 single-core Cinebench R23 score provide responsive interaction during development, while the 12 threads handle parallel builds. The 89.6 GB/s memory bandwidth supports memory-intensive applications like virtual machines and database queries.

Students and small business users who require a capable all-in-one laptop will appreciate the balance. The CPU's 3584 PassMark single-thread score handles office productivity, web browsing, and spreadsheet work smoothly. The integrated Radeon 760M provides a fallback for lighter tasks, potentially extending battery life when the discrete GPU is not needed. The 80th combined percentile indicates the system is well above average for general-purpose use.

# Gaming Performance — measured FPS by game and resolution from measuredFpsUltraByGame

The FACT PACK contains no measured FPS data for this exact combination — the measuredFpsUltraByGame field is empty, and dataIsMeasured is false. Therefore, no specific frame rates can be cited for any game or resolution. All FPS figures discussed here are estimates based on the benchmark scores and should not be treated as empirical measurements.

Given the GPU's 81st percentile ranking and the CPU's 78th percentile, the estimated gaming performance at ultra settings would be strong at 1440p and playable at 4K for most titles. The 12 GB VRAM is sufficient for high-resolution textures, and the 432.0 GB/s bandwidth supports high frame rates in bandwidth-sensitive scenarios. The 24.72 TFLOPS FP32 throughput allows for high shader complexity without dropping below playable thresholds.

At 1080p, the CPU may become the limiting factor in esports titles where frame rates exceed 144 Hz. The 1711 Cinebench R23 single-core score and 3584 PassMark single-thread score indicate adequate but not exceptional CPU throughput. For AAA games at 1080p ultra, the GPU would likely be the primary constraint, and frame rates would be high but not maximal. At 1440p, the balance shifts toward the GPU, and the system should deliver consistently high frame rates in most titles. At 4K, the GPU's 12 GB VRAM and 432.0 GB/s bandwidth become the determining factors, and performance would depend on the specific game's optimization.

Ray tracing performance would benefit from the 58 RT cores, but the 110 W TDP limits sustained clock speeds compared to desktop counterparts. DLSS via the 232 tensor cores could provide significant frame rate boosts in supported titles, though no specific uplift percentages are available in the data.

# Build Overview — what this CPU+GPU pairing is, its class, and overall tier from the percentiles

This is a laptop-class build combining the AMD Ryzen 5 8640HS with the NVIDIA GeForce RTX 4080 Mobile. The CPU is a 6-core, 12-thread Zen 4 processor from the 8000 series, codenamed Hawk Point, built on TSMC's 4 nm process. The GPU is an Ada Lovelace architecture part from the GeForce 40-series, using the AD104 chip on a 5 nm process with 35,800 million transistors.

The combined percentile is 80, placing this system in the top 20% of all CPU+GPU combinations in the database. Individually, the CPU sits at the 78th percentile and the GPU at the 81st percentile. The average benchmark scores are 26106 for the CPU and 38135 for the GPU. This pairing represents a high-tier mobile configuration where the GPU is the dominant component, but the CPU is sufficient to avoid severe bottlenecking in most workloads.

The build class is laptop, meaning both components are designed for mobile use with power constraints. The CPU's 28 W TDP and the GPU's 110 W TDP indicate a total system power draw that requires a substantial battery and cooling solution. The GPU's slot width is listed as IGP (integrated graphics processor), and power connectors are none, suggesting this is a soldered or BGA implementation rather than a modular MXM design. The display outputs are portable device dependent, meaning they vary by laptop model.

# Usage Scenarios — grounded in the scores

High-refresh gaming: The GPU's 24926 PassMark G3D score and 159575 Geekbench OpenCL score indicate strong raw graphics throughput. At 1440p, the system should sustain high frame rates in competitive titles, though the CPU's 1711 single-core Cinebench R23 score may limit extreme refresh rates above 200 Hz in CPU-bound games.

Streaming: The CPU's 12 threads, with a PassMark multi-thread score of 19889, provide enough headroom for encoding while gaming, though the 28 W TDP means sustained multi-threaded loads may cause thermal throttling. The GPU's 232 tensor cores could offload encoding via NVENC, though specific encoding performance is not in the data.

Video editing: The GPU's 24.72 TFLOPS FP32 throughput and 12 GB VRAM accelerate effects and timeline rendering. The CPU's data compression score of 226544 suggests fast file handling, and the 89.6 GB/s memory bandwidth supports large project files. Export times would be GPU-limited, which is favorable.

3D rendering: The 58 RT cores and 232 tensor cores provide dedicated hardware for ray-traced rendering and AI denoising. The 24.72 TFLOPS FP16 (1:1) throughput supports mixed-precision workloads. The 12 GB VRAM is adequate for scenes that fit within memory, but larger scenes would spill to system memory.

Software development: The CPU's 4.90 GHz boost clock and 1778 Geekbench single-core score deliver responsive compile times for small-to-medium projects. The 12 threads handle parallel builds, and the 16 MB L3 cache reduces memory latency for iterative code changes.

Student and office work: The CPU's 3584 PassMark single-thread score and the integrated Radeon 760M provide smooth performance for document editing, web browsing, and spreadsheet analysis. The 78th percentile CPU ranking ensures this system is faster than the majority of laptops in typical office tasks.

# Upgrade Path and Platform — socket, memory support, PCIe, PSU headroom, and sensible next upgrades

The CPU uses the AMD Socket FP8, which is a mobile socket designed for laptop implementations. The processor supports DDR5 memory in dual-channel configuration, providing 89.6 GB/s of memory bandwidth. PCIe support is Gen 4 with 20 lanes from the CPU. The CPU is not multiplier-unlocked, meaning overclocking is not possible. The integrated Radeon 760M provides a display output fallback.

The GPU uses a PCIe 4.0 x16 bus interface, which is standard for high-performance mobile graphics. The TDP is 110 W, and the suggested PSU field is null, meaning no specific power supply recommendation is provided. The power connectors are listed as none, indicating the GPU draws power through the motherboard rather than external connectors. The slot width is IGP, confirming this is a mobile implementation.

The upgrade path for this laptop is limited by the mobile form factor. The CPU is socketed (FP8), but in practice, laptop CPUs are often soldered or restricted to a narrow range of compatible processors. The GPU is not user-upgradeable in most laptop designs. Memory upgrades would depend on whether the DDR5 modules are soldered or in SO-DIMM slots, though this is not specified in the data. Storage upgrades via PCIe Gen 4 lanes are a plausible option, given the 20 available lanes.

A sensible next upgrade would be increasing system memory if the laptop supports it, as the 89.6 GB/s bandwidth benefits from dual-channel operation. For storage, adding a Gen 4 NVMe SSD would leverage the available PCIe lanes. The GPU's 12 GB VRAM is already substantial, so a GPU upgrade would only be meaningful if the laptop supports external graphics via Thunderbolt, which is not specified. The CPU's 78th percentile suggests that upgrading to a higher-core-count Ryzen 8000-series part would yield modest gains, but the mobile socket limits options.
