# Intel Core Ultra 9 285HX + NVIDIA GeForce RTX 4080 Mobile

This mobile flagship pairing combines Intel's top-tier Arrow Lake-HX processor with NVIDIA's Ada Lovelace GPU, targeting the upper echelon of laptop performance. The data shows a CPU that sits at the 95th percentile among all processors and a GPU at the 81st percentile, with the combined platform achieving an 88th-percentile standing. No measured FPS rows exist for this exact combination in the FACT PACK, so all frame-rate discussion below is estimated from the benchmark scores rather than observed results.

CPU Analysis

The Intel Core Ultra 9 285HX is a 24-core, 24-thread processor built on Arrow Lake-HX architecture, fabricated on TSMC's 3nm process node. It packs 17,800 million transistors into a 243 mm² die, with a base clock of 2.80 GHz and a boost clock reaching 5.50 GHz. The core configuration is unusual in that threads equal cores — no hyperthreading here — which places emphasis on raw core count and clock frequency rather than simultaneous multithreading overhead.

Cache hierarchy is substantial: 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. This arrangement gives each core a generous private cache allocation, which can benefit latency-sensitive workloads like gaming and single-threaded applications. The 36 MB L3 pool is shared across all 24 cores, providing a common high-speed storage area for frequently accessed data.

Memory support includes DDR5 with dual-channel configuration, delivering 102.4 GB/s of bandwidth. The platform supports ECC memory, which is notable for professional and workstation use cases where data integrity matters. PCIe Gen 5 with 20 lanes from the CPU provides high-bandwidth connectivity for storage and expansion.

Benchmark results position this CPU strongly. In Cinebench R23, the multi-core score of 36,429.5 and single-core score of 2,187.5 demonstrate a balanced design. The R20 multi-core score of 20,236 and single-core of 2,856 follow similar patterns. PassMark results show particularly strong integer math (155,076), floating-point math (194,998), and data compression (631,885) scores. The multithread score of 56,902 and single-thread score of 4,618 indicate this processor handles both parallel and serial workloads competently.

The average benchmark score of 76,155 places it at the 95th percentile of all CPUs. Its nearest rival is the AMD Ryzen 9 8945HX, which scores 76,212 — a delta of just -0.1%, meaning these two processors are effectively performance twins in aggregate benchmarks. The AMD Ryzen 9 9950X3D scores 75,779, trailing by 0.5%. The AMD EPYC Embedded 8224P (76,492) and AMD Ryzen Threadripper PRO 9945WX (76,513) are both marginally ahead by 0.4-0.5%, suggesting this mobile chip trades blows with server and workstation parts.

What this means for real workloads: the 24 physical cores excel at heavily parallelized tasks like video encoding, 3D rendering, and compilation. The high boost clock of 5.50 GHz ensures snappy single-threaded performance in applications that rely on one or two cores. The PassMark physics score of 3,476 and extended instructions score of 49,148 further confirm strong computational throughput.

Benchmark Performance

The CPU's Cinebench R15 multi-core score of 5,656.5 and single-core of 323.5 establish a baseline for legacy benchmark comparisons. R20 and R23 results scale appropriately, showing the processor maintains efficiency across benchmark generations. PassMark data encryption (48,567) and random string sorting (77,196) scores indicate solid cryptographic and data manipulation capabilities.

On the GPU side, the RTX 4080 Mobile delivers a Geekbench OpenCL score of 159,575 and Vulkan score of 145,807. PassMark G3D score is 24,926, with GPU compute at 11,191. The average benchmark score of 38,135 places this GPU at the 81st percentile of all GPUs. Interestingly, its nearest rival is the NVIDIA GeForce MX570 at 38,299, a delta of -0.4% — though this likely reflects benchmark aggregation quirks rather than genuine parity, given the architectural differences. The RTX 5080 Mobile scores 38,349 (0.6% ahead), while the RTX 4070 desktop card scores 37,648 (1.3% behind).

The combined picture shows a platform where the CPU is notably stronger relative to its peers than the GPU. The CPU sits 14 percentile points higher than the GPU, suggesting this pairing prioritizes processor-heavy workloads. The combined percentile of 88 reflects a system that is firmly in enthusiast territory but not at the absolute top of either component category.

Gaming performance estimates derive from these scores. The CPU's 95th percentile ensures it will not bottleneck modern titles, while the GPU's 81st percentile indicates strong but not class-leading rasterization. The PassMark DirectX scores — 286 for DX9, 244 for DX11, 96 for DX12, and 157 for DX10 — suggest the GPU performs best in older API titles relative to its overall standing, while newer DX12 workloads may not scale as efficiently.

GPU Analysis

The NVIDIA GeForce RTX 4080 Mobile uses the AD104 chip on TSMC's 5nm process, containing 35,800 million transistors across a 294 mm² die. The transistor density of 121.8M per mm² is high, reflecting the mature 5nm node. Base clock is 1,290 MHz with a boost clock of 1,665 MHz, and memory runs at 2,250 MHz with 18 Gbps effective throughput.

Memory configuration includes 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. This is adequate for 1440p gaming and most creative workloads, though the 192-bit bus width is narrower than desktop RTX 4080-class parts. Shading units number 7,424 with 232 TMUs and 80 ROPs. The pixel rate of 133.2 GPixel/s and texture rate of 386.3 GTexel/s indicate solid fill rates for high-resolution rendering.

Ray tracing and tensor hardware are present: 58 RT cores and 232 tensor cores. These enable hardware-accelerated ray tracing and DLSS features. FP32 performance is rated at 24.72 TFLOPS, with FP16 at the same 1:1 ratio — this means no dedicated half-precision acceleration, which could affect certain AI workloads that benefit from FP16 throughput.

The GPU's TDP is 110 W, which is modest for a "4080" class part, reflecting mobile power constraints. It uses no power connectors (IGP slot width), meaning it draws power through the motherboard as part of a laptop design. PCIe 4.0 x16 interface provides sufficient bandwidth for the 12 GB frame buffer.

For rendering workloads, the 24.72 TFLOPS of FP32 compute places this GPU above typical mobile parts but below desktop high-end cards. The Vulkan score of 145,807 and OpenCL of 159,575 suggest strong compute capability for GPU-accelerated rendering in applications like Blender or Octane. The PassMark G3D score of 24,926 indicates solid rasterization performance, though the DirectX 12 score of 96 is comparatively low, possibly reflecting driver overhead or benchmark-specific inefficiencies.

Who Should Build It

The 95th-percentile CPU makes this platform ideal for professionals who need maximum processor throughput in a portable form factor. Software developers compiling large codebases will benefit from the 24 cores and high boost clocks. Video editors working with multi-track timelines and effects-heavy projects will see strong performance in both CPU-based encoding and GPU-accelerated effects.

Content creators handling 3D rendering, particularly those using CPU-based renderers, will find the 36,429.5 Cinebench R23 multi-core score translates to reduced render times. The 102.4 GB/s memory bandwidth and ECC support make this suitable for scientific computing and data analysis where data integrity matters.

Gamers at 1440p and 4K resolutions will find the GPU adequate, though not the absolute fastest mobile option. The 81st-percentile GPU handles most titles at high settings, while the CPU ensures no processor bottleneck at any resolution. Students in engineering or computer science programs will appreciate the compile times and simulation performance, though the laptop-class platform requires adequate cooling.

Small business workstations handling financial modeling, database operations, or virtualization can leverage the 24 threads and high PassMark multithread score of 56,902. The data encryption score of 48,567 indicates strong performance for secure communications and encrypted storage.

Balance and Bottleneck

The data reveals a CPU-heavy platform. With the CPU at the 95th percentile and GPU at the 81st, the processor is the stronger component by a wide margin. In CPU-bound workloads — compilation, rendering, data compression — the system will perform at near-flagship levels. In GPU-bound workloads like gaming at 4K or GPU rendering, the RTX 4080 Mobile becomes the limiting factor.

The nearest rival deltaPct values reinforce this imbalance. The CPU trades blows with the AMD Ryzen 9 8945HX (delta -0.1%) and Ryzen 9 9950X3D (delta +0.5%), both of which are desktop-class parts. Meanwhile, the GPU's nearest rivals include the MX570 and RTX 5080 Mobile, with deltas under 1.3% — suggesting the GPU is closer to mid-pack competitors than to top-tier mobile GPUs.

For gaming, the CPU's 5.50 GHz boost clock and 36 MB L3 cache will drive high frame rates in CPU-heavy titles. The GPU's 432.0 GB/s bandwidth and 12 GB VRAM are sufficient for 1440p, but at 4K the GPU will bottleneck first. For productivity, the CPU's multi-core dominance means the platform excels at parallel workloads, while the GPU provides adequate acceleration for video transcoding and GPU-assisted effects.

The PassMark physics score of 3,476 and single-thread score of 4,618 indicate the CPU can handle physics simulation and game logic without slowing down. The GPU's DirectX 12 score of 96 suggests potential driver-level inefficiencies in modern API workloads, which could manifest as lower frame rates in DX12-only titles compared to DX11 equivalents.

Gaming Performance

No measured FPS data exists for this exact CPU+GPU combination in the FACT PACK — this must be stated clearly. All gaming figures below are estimates derived from the benchmark scores, not observed results.

Based on the GPU's 81st-percentile standing and the CPU's 95th percentile, this system should deliver strong 1440p gaming performance. The 12 GB VRAM and 432.0 GB/s bandwidth are adequate for high-texture settings at 1440p. At 4K, the GPU's 80 ROPs and 24.72 TFLOPS will struggle with maximum settings in demanding titles, though DLSS via the 232 tensor cores can mitigate this.

The PassMark DirectX 11 score of 244 is notably higher than the DirectX 12 score of 96, suggesting this GPU performs relatively better in legacy API titles. Players of DX11 games like older AAA releases or MMOs should see excellent frame rates. DX12 titles may show lower performance relative to the GPU's overall capability.

The CPU's high single-thread performance (4,618 PassMark single-thread) ensures consistent frame pacing in CPU-bound scenarios. The 36 MB L3 cache helps with open-world games that stream large amounts of data. Competitive multiplayer titles at 1080p or 1440p with high refresh rates should benefit from the CPU's boost clock and the GPU's 133.2 GPixel/s fill rate.

For ray tracing, the 58 RT cores provide hardware acceleration, though the 110 W TDP limits sustained performance. Expect playable ray-traced frame rates at 1440p with DLSS enabled, but lower performance without upscaling.
