The AMD Ryzen 9 7940H paired with the Intel Arc B390 is a laptop configuration that presents a stark contrast in performance tiers. The CPU is a high-end 8-core mobile processor, while the GPU is an entry-level integrated graphics solution, resulting in a system where the processor's capabilities far outstrip the graphics subsystem. This analysis relies entirely on the provided benchmark data to explain what this pairing means for various workloads.

FAQ

Q: How does the CPU's multi-threaded performance compare to its nearest rivals?

A: The Ryzen 9 7940H scores 24,703 points in Cinebench R23 multi-core. Its average benchmark score of 40,431 places it within 0.3% of the Intel Xeon 6369P and 0.3% ahead of the Intel Core i9-13905H, indicating it is effectively performance-equivalent to those high-end desktop-class chips in overall CPU workloads.

Q: The GPU scores in the 9th percentile of all GPUs. What does that mean for gaming?

A: The Intel Arc B390's 3DMark Steel Nomad DX12 score of 1,482 places it in the 9th percentile, meaning it performs worse than 91% of all GPUs. Its closest rivals are the NVIDIA GeForce GT 710 and GT 625 OEM, which are very old entry-level discrete cards. This indicates the GPU is only suitable for the lightest gaming workloads at low settings and resolutions.

Q: Is the CPU's integrated graphics more powerful than the dedicated Arc B390?

A: The data does not contain a direct comparison of the Radeon 780M integrated graphics versus the Intel Arc B390. However, the Arc B390 is a separate GPU with its own benchmark score of 1,482, positioning it as a very basic graphics processor, while the CPU's integrated Radeon 780M is listed as a feature but has no separate benchmark score provided.

Q: What kind of memory bandwidth does the platform support?

A: The Ryzen 9 7940H supports dual-channel DDR5 memory with a maximum memory bandwidth of 89.6 GB/s. The GPU's memory bandwidth is listed as "System Dependent" since it uses shared system memory, meaning its performance will be tied to the speed and configuration of the installed RAM.

Q: Is this CPU better suited for single-threaded or multi-threaded tasks?

A: The data indicates strong performance in both areas. In Cinebench R23, it scores 3,487 in single-core and 24,703 in multi-core, showing a roughly 7x scaling with the 8 cores and 16 threads. The PassMark single-thread score of 3,952 and the multithread score of 29,063 further confirm it is a capable processor for both lightly-threaded and heavily-threaded workloads.

Q: What is the GPU's architecture and feature set?

A: The Intel Arc B390 is based on the Xe3-LPG architecture on a 3 nm process and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. It has 12 ray tracing cores and a boost clock of 2500 MHz, but its raw computing power is limited to 7.680 TFLOPS FP32.

Q: How does this laptop's overall performance rank compared to other systems?

A: The build has a combined percentile of 48, placing it in the middle of all benchmarked systems. This combined score is heavily influenced by the CPU's high 87th percentile ranking, which is dragged down by the GPU's low 9th percentile ranking.

Usage Scenarios

High-Refresh Gaming: This is not a viable scenario for this build. The Intel Arc B390's 3DMark Steel Nomad score of 1,482 places it in the 9th percentile, a tier alongside the NVIDIA GeForce GT 710. This level of performance is insufficient to drive high refresh rates at any modern resolution, and the estimated FPS would be far below what is needed for a smooth high-refresh experience.

Streaming: The CPU is more than capable of handling the encoding workload for a stream. Its Cinebench R23 multi-core score of 24,703 is a top-tier result, ensuring that x264 encoding will not impact game performance. However, the GPU is the bottleneck, as it will struggle to render modern games at playable frame rates, making the overall streaming experience poor due to the source gameplay being choppy.

Video Editing: The CPU's strong multi-threaded performance, evidenced by its PassMark multithread score of 29,063, will accelerate video encoding and effects processing. The GPU, however, will be a significant limiting factor. Its low 1,482 Steel Nomad score and 9th percentile ranking mean it cannot accelerate modern effects or handle high-resolution timelines efficiently, making any GPU-accelerated workflow impractical.

3D Rendering: This is a CPU-dominated task, and the Ryzen 9 7940H excels here. Its Cinebench R23 multi-core score of 24,703 and an average benchmark score of 40,431 place it in the 87th percentile of all CPUs. This indicates that CPU-based rendering will be very fast. The GPU's role in rendering is minimal, and its low 7.680 TFLOPS FP32 performance means it is not a viable option for GPU-accelerated renderers.

Software Development: The CPU is a strong asset for developers. The high single-threaded performance (3,952 PassMark score) speeds up code compilation of single files, while the multi-threaded score of 29,063 will significantly reduce full-project build times. The GPU is largely irrelevant for this use case, meaning the system is well-balanced for a developer who does not game on the same machine.

Student and Office Work: For everyday productivity, this is a very capable system. The CPU provides a snappy and responsive experience for web browsing, document editing, and spreadsheets. The GPU is more than sufficient for basic desktop rendering and 2D acceleration. Its performance is a non-issue for these tasks, making the system feel fast and responsive due to the powerful processor.

CPU Analysis

The AMD Ryzen 9 7940H is a mobile processor from the 7000 series, built on the Zen 4 architecture (codenamed Phoenix) using a 4 nm process from TSMC. It features 8 cores and 16 threads, with a base clock of 4.00 GHz and a boost clock of 5.20 GHz. This high boost clock, combined with the modern architecture, yields an excellent single-threaded score of 3,487 in Cinebench R23 and 3,952 in PassMark's single-thread test.

The multi-threaded performance is equally impressive. The Cinebench R23 multi-core score of 24,703 and the PassMark multithread score of 29,063 place the chip in the 87th percentile of all CPUs. Its average benchmark score of 40,431 is virtually identical to that of the Intel Xeon 6507P and Intel Core i9-13905H, showing that this 35W TDP mobile chip competes with much higher-power desktop parts. This makes it an exceptional choice for any CPU-intensive workload.

The processor supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s and includes ECC memory support, which is a feature often found in professional workstations. It has 16 MB of shared L3 cache and a 1 MB L2 cache per core, which helps in maintaining high performance across a variety of tasks. The integrated Radeon 780M graphics is present, but its performance is not measured in this data. The CPU's performance profile is that of a high-end workstation-class processor.

Balance and Bottleneck

This build is defined by a massive imbalance between the CPU and GPU. The CPU's performance is in the 87th percentile of all CPUs, while the GPU is in the 9th percentile. This means the GPU will be the primary bottleneck in any workload that requires 3D graphics rendering, such as gaming.

In gaming, the CPU is so powerful that it will not be the limiting factor. The estimated frame rates will be determined almost entirely by the Intel Arc B390's 1,482 Steel Nomad score. The GPU's performance is comparable to that of the NVIDIA GeForce GT 710, which means it will struggle to push 30 FPS in most modern games, even at 720p with the lowest settings. The CPU will be waiting idly for the GPU to finish rendering each frame.

Conversely, in CPU-bound tasks like video encoding, 3D rendering, or data compression (PassMark score of 352,077), the GPU is irrelevant. Here, the Ryzen 9 7940H operates at its full potential, delivering top-tier performance. The system's combined percentile of 48 is a direct result of this imbalance, representing an average of a very high CPU score and a very low GPU score. The performance of the system is entirely dependent on which component the specific software is using.

Who Should Build It

This is a niche configuration. The primary target users are those who require extreme CPU performance for professional or technical work but have no need for 3D gaming or GPU-accelerated rendering.

Software Developers: The high single-core and multi-core scores make compiling large codebases very fast.
Data Analysts and Scientists: The strong CPU performance for data compression (352,077) and encryption (21,096) makes it suitable for processing large datasets.
Students and Professionals in STEM: For coursework or work involving heavy computation, simulation, or CPU-based programming, this is an excellent machine.
Small Business Workstations: For tasks like financial modeling, database management, or software testing, the CPU provides a significant performance advantage.

It is not recommended for gamers, video editors who rely on GPU acceleration, or 3D artists who use GPU renderers. The Arc B390's performance is simply too low to be considered a gaming or professional graphics solution, making the system poorly balanced for those tasks.

Gaming Performance

The FACT PACK contains no measured FPS data for this combination, so all frame rates discussed here are estimates based on the GPU's 3DMark Steel Nomad score of 1,482 and its 9th percentile ranking. This score places the Intel Arc B390 in the same performance class as the NVIDIA GeForce GT 710, which is a very old entry-level card.

Given this, estimated gaming performance is extremely low. At 1080p with ultra settings, this system would likely fail to achieve playable frame rates in most modern titles. For esports titles like CS:GO or League of Legends, which are not graphically demanding, it might be possible to achieve 30-60 FPS at 720p with very low graphics settings. For any AAA game from the last several years, the estimated performance would be below 30 FPS, even at 720p.

The GPU has 12 ray tracing cores, but its raw compute power of 7.680 TFLOPS is insufficient to handle the overhead of ray tracing in modern games. Enabling ray tracing would likely make the frame rates drop to single digits. The 24 ROPs and 48 TMUs are also very low numbers, further limiting fill-rate and texture processing. In short, this is not a gaming laptop, and the estimated FPS figures are only suitable for the oldest or least demanding 2D games.

Benchmark Performance

The combined picture from the benchmarks is one of stark contrast. The AMD Ryzen 9 7940H is a top-tier CPU, with its average benchmark score of 40,431 placing it in the 87th percentile of all CPUs. It is statistically tied with the Intel Xeon 6507P (40,426) and the Intel Core i9-13905H (40,313), showing its high-end positioning.

In contrast, the Intel Arc B390 is a bottom-tier GPU. Its average benchmark score is only 1,482, placing it in the 9th percentile of all GPUs. Its closest rivals are the NVIDIA GeForce GT 520MX, GT 800M, and GT 625 OEM, all of which are ancient, low-power parts. The deltaPct values are very small, meaning their performance is nearly identical.

The system's combined percentile of 48 is a direct mathematical average of these two extremes. The CPU's strong scores in Cinebench R23 (24,703 multi-core, 3,487 single-core) and various PassMark tests (29,063 multithread, 101,977 integer math) are the system's primary strengths. The GPU's sole 3DMark result is its primary and only measurable weakness.

Build Overview

This is a laptop-class build pairing an AMD Ryzen 9 7940H processor with an Intel Arc B390 integrated GPU. The CPU is an 8-core, 16-thread mobile powerhouse from the Zen 4 architecture, while the GPU is a low-power integrated part from Intel's Xe3-LPG architecture.

The overall tier of this system is mid-range, as indicated by its combined percentile of 48. However, this single number is misleading. The system is simultaneously a high-end workstation-class CPU platform and an entry-level GPU platform. It is a machine of extremes, offering exceptional processing power for CPU-intensive tasks while providing a graphics experience that is only suitable for basic computing.

This is not a balanced gaming or content-creation system. It is a specialized tool for users who need maximum processor performance in a laptop form factor and are willing to accept the very weak integrated graphics as a consequence. The pairing is logical only for a very specific professional or developer audience.

GPU Analysis

The Intel Arc B390 is an integrated GPU (IGP) based on the Xe3-LPG architecture, built on Intel's 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The GPU uses System Shared memory, meaning its VRAM size, type, and bus width are not fixed and are dependent on the system's RAM. Its memory bandwidth is also listed as "System Dependent."

The GPU is equipped with 1,536 shading units, 48 TMUs, and 24 ROPs. It also includes 12 dedicated ray tracing cores. Its theoretical performance is rated at 7.680 TFLOPS for FP32 operations and 15.36 TFLOPS for FP16 (2:1). The pixel rate is 60.00 GPixel/s and the texture rate is 120.0 GTexel/s.

In 3DMark Steel Nomad DX12, it scores only 1,482, which places it in the 9th percentile. This result is nearly identical to the NVIDIA GeForce GT 520MX (1,463) and GT 625 OEM (1,446). This indicates that despite its modern architecture and features like DirectX 12 Ultimate and Vulkan 1.4, its raw rendering power is on par with graphics solutions from over a decade ago. The ray tracing cores are present, but the GPU's overall compute performance is too low to make use of them effectively in modern games. For rendering, its 7.680 TFLOPS FP32 is a negligible amount compared to any dedicated GPU, making it unsuitable for any serious 3D rendering work.
