# AMD Ryzen 5 5625C + NVIDIA GeForce RTX 4090 Mobile

This pairing combines a low-power 6-core Zen 3 mobile processor with NVIDIA's flagship 40-series laptop GPU, creating a lopsided but potent configuration. The CPU is a 15 W part designed for efficiency, while the GPU is a 120 W monster with 16 GB of GDDR6 memory. The data shows a system where the GPU dominates every benchmark category, and the CPU's 50th percentile standing among all CPUs contrasts sharply with the GPU's 84th percentile rank. This is a laptop-class build (buildClass: "laptop") with a combined percentile of 67, indicating that the whole system sits above the median but is pulled down significantly by the modest processor.

Upgrade Path and Platform

The AMD Ryzen 5 5625C is built on the AMD Socket FP6 platform, which is a mobile-specific socket. This is a soldered or BGA-style socket, meaning the CPU is not user-replaceable in most laptop designs. The platform uses the Cezanne-U codename and is based on the Zen 3 architecture, manufactured on TSMC's 7 nm process. The CPU supports DDR4 memory in a dual-channel configuration, providing 51.2 GB/s of memory bandwidth. ECC memory is not supported. The PCIe implementation is Gen 3 with 8 lanes from the CPU only, which is a notable limitation for a system paired with a high-end GPU that supports PCIe 4.0 x16.

The GPU, by contrast, uses a PCIe 4.0 x16 bus interface, which means the connection between the CPU and GPU is bottlenecked by the CPU's PCIe Gen 3 lanes. This is a platform mismatch that will affect data transfer speeds in GPU-intensive workloads. The CPU's TDP is 15 W, while the GPU's TDP is 120 W, making the GPU eight times more power-hungry. The suggested PSU field is null for the GPU, and since this is an IGP (integrated graphics package) slot width with no power connectors, the laptop's power delivery system handles both components. The practical implication is that the CPU's ultra-low power envelope leaves plenty of thermal and power headroom for the GPU to boost, but the CPU itself will not be able to feed the GPU fast enough in many scenarios.

A sensible next upgrade on this platform would be limited to replacing the GPU in a future laptop, as the CPU is not upgradable. The data shows that the GPU is the clear performance driver, so any future system should prioritize keeping a similar or better GPU while upgrading to a higher-tier CPU with more cores and higher TDP to balance the system. The CPU's 6 cores and 12 threads at 2.30 GHz base and 4.30 GHz boost are sufficient for basic tasks, but for gaming or content creation at the level this GPU can handle, a more powerful processor would be required to avoid leaving GPU performance on the table.

Benchmark Performance

The GPU benchmark data is extensive, with multiple scores across different APIs. The Geekbench OpenCL score is 180,831, and the Vulkan score is 170,774, showing strong compute performance across both major graphics APIs. The Passmark G3D score is 27,212, which is the primary gaming-oriented metric. The Passmark GPU Compute score is 12,347, indicating solid general-purpose compute. The DirectX scores vary significantly: DirectX 10 at 173, DirectX 11 at 262, DirectX 12 at 107, and DirectX 9 at 310. The DirectX 12 score being lower than DirectX 11 is noteworthy, as it suggests the GPU's performance in modern APIs may be limited by other factors in this system context.

The GPU's average benchmark score is 43,667, placing it in the 84th percentile among all GPUs. Its nearest rivals include the NVIDIA Quadro M6000 with an average score of 43,301 (0.8% ahead of the RTX 4090 Mobile), the NVIDIA GeForce RTX 5050 Mobile at 43,268 (0.9% ahead), the NVIDIA Quadro M6000 24 GB at 43,262 (0.9% ahead), and the NVIDIA RTX A6000 at 44,075 (0.9% behind). This means the RTX 4090 Mobile sits in a tight cluster of professional and mobile GPUs, all within roughly 1% of each other, with the RTX A6000 being the only one that scores slightly higher.

The CPU has no benchmark scores and no nearest rivals in the data, with an average benchmark score of 0. Its percentile versus all CPUs is 50, placing it exactly at the median. This is a stark contrast to the GPU's 84th percentile. The combined percentile for the build is 67, which reflects the GPU's strong performance diluted by the CPU's mediocrity. No measured FPS rows exist for this exact combination — the FACT PACK contains no measuredFps data. All FPS discussion must therefore be treated as estimated from the benchmark scores rather than directly measured.

Balance and Bottleneck

The balance of this system is heavily skewed toward the GPU. The CPU sits at the 50th percentile among all CPUs, while the GPU sits at the 84th percentile — a 34-point gap. In practical terms, the GPU is capable of far more work than the CPU can feed it. The CPU has 6 cores and 12 threads, which is adequate for many workloads, but its 15 W TDP and 2.30 GHz base clock limit sustained performance. The boost clock of 4.30 GHz helps in short bursts, but the low TDP means the CPU will throttle under sustained load, especially when the GPU is also drawing power.

For gaming workloads, the GPU's Passmark G3D score of 27,212 suggests it can handle high-resolution and high-detail gaming, but the CPU's 50th percentile ranking means it will likely be the limiting factor at lower resolutions where frame rates are CPU-bound. At higher resolutions, the GPU becomes the bottleneck, but the CPU's PCIe Gen 3 interface with only 8 lanes will also restrict data transfer rates, potentially reducing the GPU's effective performance compared to a system with a PCIe Gen 4 CPU.

For compute workloads, the GPU's Geekbench OpenCL score of 180,831 and Vulkan score of 170,774 indicate strong parallel processing capability, but the CPU's lack of benchmark scores means its contribution to overall system performance is unquantified beyond its percentile. The GPU's Passmark GPU Compute score of 12,347 further confirms its compute strength. The CPU's 16 MB of L3 cache and 512 KB L2 per core are modest, which will impact workloads that rely on large datasets being processed sequentially.

The bottleneck analysis is clear: the GPU is the performance driver, and the CPU is the limiter. In GPU-heavy workloads like 3D rendering or high-resolution gaming, the GPU will be utilized well, but in CPU-heavy tasks like physics simulations or single-threaded games, the system will feel sluggish. The FPS scaling, estimated from the benchmark scores rather than measured, would show that frame rates at 1080p or 1440p would be constrained by the CPU, while 4K frame rates would be more GPU-bound but still limited by the PCIe Gen 3 connection.

CPU Analysis

The AMD Ryzen 5 5625C is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Cezanne-U. It is manufactured on TSMC's 7 nm process with 10,700 million transistors on a 180 mm² die. The base clock is 2.30 GHz, and the boost clock is 4.30 GHz, giving it a reasonable single-thread capability for bursty workloads. The TDP is 15 W, which is extremely low for a processor with these specifications, indicating a focus on battery life and thermal efficiency in thin-and-light laptops.

The cache hierarchy consists of 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache. This is a modest amount of cache by modern standards, but it is appropriate for a low-power mobile part. The memory support is DDR4 in dual-channel mode, providing 51.2 GB/s of bandwidth, which is sufficient for the CPU's needs but will bottleneck the GPU's data access. The integrated graphics is Radeon Vega 7, which provides basic display output but is not designed for gaming or compute tasks.

The CPU has no benchmark scores in the FACT PACK, so its performance can only be inferred from its 50th percentile ranking among all CPUs. This places it exactly at the median, meaning it is neither a standout performer nor a weak link in general CPU terms. For real workloads, this means the CPU can handle everyday tasks like web browsing, office applications, and light multitasking without issue, but it will struggle with heavy multi-threaded workloads like video encoding or 3D rendering, where higher-core-count processors would excel. The boost clock of 4.30 GHz helps with single-threaded tasks, but the low TDP will cause the clock to drop under sustained load.

Who Should Build It

This build targets users who need GPU-heavy performance in a laptop form factor but do not require top-tier CPU performance. Gamers who play at high resolutions (1440p or 4K) would benefit from the GPU's 84th percentile ranking, as the GPU will be the primary driver of frame rates at those settings. The GPU's 16 GB of VRAM is ample for modern game textures, and the 576.0 GB/s bandwidth ensures high-resolution textures load quickly. However, gamers who play at 1080p with high refresh rates would find the CPU's 50th percentile ranking a limiting factor, as the CPU would struggle to keep up with the GPU's frame generation.

Content creators who work primarily with GPU-accelerated applications, such as video editing software that uses CUDA or OpenCL, would see strong performance from the RTX 4090 Mobile's 180,831 OpenCL score. The GPU's 76 RT cores and 304 tensor cores make it well-suited for ray-traced rendering and AI-accelerated workloads. Developers who write GPU compute code or machine learning models would benefit from the GPU's compute capabilities, though the CPU's modest performance would limit compilation times and other CPU-bound tasks.

Students and small business users who run office applications, web-based tools, and light productivity software would find this build more than sufficient, as the CPU's 50th percentile ranking is adequate for these tasks, and the GPU provides headroom for occasional graphics work. However, these users would likely be overspending on the GPU, as they would not utilize its full potential. The build is best suited for users who prioritize GPU performance above all else and are willing to accept CPU limitations.

GPU Analysis

The NVIDIA GeForce RTX 4090 Mobile is based on the AD103 chip using the Ada Lovelace architecture, manufactured on TSMC's 5 nm process with 45,900 million transistors on a 379 mm² die. It has 16 GB of GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of memory bandwidth. The base clock is 1335 MHz, and the boost clock is 1695 MHz, with memory running at 2250 MHz (18 Gbps effective). The GPU has 9,728 shading units, 304 TMUs, and 112 ROPs, along with 76 RT cores and 304 tensor cores.

The pixel rate is 189.8 GPixel/s, and the texture rate is 515.3 GTexel/s, indicating strong fill rates for high-resolution rendering. The FP32 performance is 32.98 TFLOPS, and FP16 performance is also 32.98 TFLOPS (1:1 ratio), which is notable for compute workloads that can use reduced precision. The TDP is 120 W, and the slot width is listed as IGP with no power connectors, meaning it is designed for laptops where power is delivered through the motherboard.

The GPU's benchmark scores show a strong overall performer. The Passmark G3D score of 27,212 places it in the 84th percentile, and its average benchmark score of 43,667 puts it in a tight race with professional GPUs like the Quadro M6000 and RTX A6000, all within 1% of each other. The DirectX scores are mixed: DirectX 9 at 310 is the highest, DirectX 11 at 262 is solid, DirectX 10 at 173 is moderate, and DirectX 12 at 107 is notably low. This suggests the GPU performs best in older APIs and may be limited by driver or architecture in DirectX 12 workloads. The Passmark G2D score of 984 is low, indicating that 2D graphics performance is not a strength.

For rendering workloads, the GPU's RT cores and tensor cores provide hardware acceleration for ray tracing and AI-based features, making it capable of real-time ray-traced gaming and accelerated rendering in applications that support these features. The 16 GB of VRAM is generous, allowing large scenes and high-resolution textures to fit in memory without swapping.

Build Overview

This build pairs the AMD Ryzen 5 5625C with the NVIDIA GeForce RTX 4090 Mobile in a laptop class configuration. The build class is "laptop," meaning all components are designed for mobile use with power and thermal constraints. The combined percentile is 67, which places this system above the median but not in the top tier. The GPU's 84th percentile ranking is the standout feature, while the CPU's 50th percentile ranking drags the overall score down.

The overall tier of this build is mid-to-high, driven almost entirely by the GPU. The CPU is a low-power efficiency part that is common in thin-and-light laptops, while the GPU is a flagship mobile part that is typically found in high-end gaming or workstation laptops. This combination is unusual — most laptops with this GPU would have a higher-end CPU to match the GPU's performance level. The result is a system that excels at GPU-bound tasks but underperforms in CPU-bound tasks relative to its GPU capability.

The build's strengths are its GPU performance, VRAM capacity, and memory bandwidth, which make it suitable for gaming at high resolutions, GPU-accelerated content creation, and compute workloads. Its weaknesses are the CPU's low core count, low TDP, and PCIe Gen 3 limitation, which bottleneck the GPU's potential and limit the system's ability to handle multi-threaded CPU workloads. This is a system for users who know they will be GPU-bound most of the time and are willing to accept CPU limitations.

Usage Scenarios

High-refresh gaming: At 1080p with a high-refresh monitor, the CPU's 50th percentile ranking will limit frame rates, as the CPU cannot feed the GPU fast enough to exceed roughly 100-150 FPS in most games. At 1440p or 4K, the GPU's 84th percentile ranking and 27,212 G3D score will drive frame rates, but the CPU's PCIe Gen 3 interface will still cap performance. This system is better suited for 1440p or 4K gaming at 60-120 FPS than for competitive 1080p gaming.

Streaming: The GPU's NVENC encoder (implied by the Ada Lovelace architecture, though not explicitly listed) would handle video encoding, offloading this task from the CPU. The CPU's 6 cores and 12 threads can handle streaming software plus game logic at moderate settings, but the low TDP may cause frame drops in CPU-intensive scenes. The 16 GB VRAM ensures headroom for game plus streaming buffers.

Video editing: GPU-accelerated effects and rendering will be fast, given the GPU's 180,831 OpenCL score and 12,347 Passmark GPU Compute score. Timeline scrubbing and preview rendering will be smooth, but export times may be limited by the CPU's modest multi-threaded performance, especially for codecs that rely on CPU encoding.

3D rendering: This is where the GPU shines. The RT cores and tensor cores accelerate ray-traced rendering, and the 16 GB VRAM allows large scenes to fit in memory. The GPU's 32.98 TFLOPS FP32 performance provides strong compute throughput, making this a capable system for GPU-based renderers like Octane or Redshift. CPU-based rendering would be slow due to the CPU's 6 cores and 50th percentile ranking.

Software development: Compilation times will be moderate, as the CPU's 6 cores and 12 threads are adequate but not fast. The GPU can accelerate parallel workloads like unit testing or data processing, and the 16 GB VRAM is useful for GPU compute development. However, the low TDP CPU may throttle during long build processes.

Student and office work: This build is overkill for typical student or office tasks, but it handles them easily. The CPU's 50th percentile ranking is sufficient for word processing, spreadsheets, web browsing, and video conferencing. The GPU remains idle most of the time, but it is available for occasional graphics work or presentations. Battery life would be poor due to the GPU's 120 W TDP, even if the CPU is efficient at 15 W.
