The Intel Core Ultra 7 255HX paired with the AMD Radeon 780M represents a specific laptop configuration where a high-end, multi-core CPU is combined with an integrated graphics solution. This analysis relies exclusively on the benchmark scores and specifications provided, as no measured FPS data exists for this exact combination in the database. All frame rate discussions are therefore estimates based on the relative performance of the CPU and GPU components.

Gaming Performance

The FACT PACK contains no measured FPS rows for this exact CPU+GPU combination, so all gaming performance figures are estimates derived from the benchmark scores of the individual components. The AMD Radeon 780M, with its 61st percentile ranking among all GPUs, is positioned as a capable integrated graphics processor, but it is not designed for high-end gaming workloads. Its average benchmark score of 17,588 places it in a competitive tier with dedicated GPUs like the AMD Radeon Pro 560, which scores 17,551, and the NVIDIA GeForce RTX 4060, which scores 17,639.

For esports titles and older games, the Radeon 780M should provide playable frame rates at 1080p with medium to high settings, given its 8.909 TFLOPS of FP32 compute performance. The 12 ray tracing cores suggest that modern games with ray tracing enabled will likely see significant performance degradation, as the GPU lacks the dedicated hardware throughput of higher-tier discrete solutions. The 768 shading units and 32 ROPs indicate that pixel fill rate is limited to 92.80 GPixel/s, which will constrain performance at higher resolutions like 1440p or 4K.

At 1080p resolution, the combination of the Core Ultra 7 255HX’s strong single-thread performance and the Radeon 780M’s integrated graphics should deliver smooth gameplay in competitive shooters and MOBA titles. However, for AAA games at higher graphical presets, the GPU will likely become the limiting factor, with estimated frame rates dropping below 30 FPS in demanding scenes. The 3DMark Steel Nomad DX12 score of 480 reinforces this assessment, indicating that the GPU is entry-level for modern DirectX 12 titles.

GPU Analysis

The AMD Radeon 780M is built on the RDNA 3.0 architecture, specifically the Phoenix chip, manufactured on a 4 nm process by TSMC. It contains 25,390 million transistors on a 178 mm² die, with a transistor density of 142.6 million per mm². The GPU operates at a base clock of 800 MHz and boosts up to 2900 MHz, which is a substantial boost range that allows for significant performance scaling under load.

Memory configuration is entirely system-shared, meaning the GPU uses the same DDR5 memory pool as the CPU. The memory bus width is also system-shared, and bandwidth is system-dependent, which means that the dual-channel memory support of the CPU, rated at 102.4 GB/s, determines the GPU’s effective memory bandwidth. This shared memory architecture can introduce performance bottlenecks in memory-intensive workloads, as the CPU and GPU compete for the same bandwidth.

The Radeon 780M features 768 shading units, 48 texture mapping units, and 32 ROPs, with a texture rate of 139.2 GTexel/s. The FP32 performance of 8.909 TFLOPS is identical to the FP16 rate of 8.909 TFLOPS, indicating a 1:1 ratio that is characteristic of consumer-focused RDNA architectures. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it compatible with the latest graphics APIs. The 12 RT cores provide hardware-accelerated ray tracing, though the overall compute throughput suggests that ray tracing workloads will be modest at best.

In benchmark performance, the Geekbench OpenCL score of 18,602 and Vulkan score of 33,683 demonstrate solid compute capabilities for an integrated GPU. The 61st percentile ranking places it above the median GPU, and its average score of 17,588 is remarkably close to the NVIDIA GeForce RTX 4060, which scores 17,639, a delta of -0.3 percent. This proximity is notable, though it does not imply equivalent gaming performance, as the RTX 4060 is a discrete GPU with dedicated VRAM.

Benchmark Performance

The Intel Core Ultra 7 255HX achieves a 93rd percentile ranking among all CPUs, with an average benchmark score of 62,738. This places it in the upper echelon of mobile processors. Its nearest rivals include the AMD Ryzen AI Embedded P185 with an average score of 62,839 and a delta of -0.2 percent, the AMD Ryzen AI 9 PRO 465 with 62,498 and a delta of 0.4 percent, and the Intel Core i7-13790F with 63,080 and a delta of -0.5 percent. The performance differences are minimal, all within one percent, indicating that the Core Ultra 7 255HX is precisely positioned in a highly competitive performance tier.

The CPU’s Cinebench scores are particularly strong. In Cinebench R23, it scores 32,612 in multi-core and 2,163 in single-core tests. The multi-core score highlights the significant parallel processing capability of the 20 cores and 20 threads, while the single-core score benefits from the 5.20 GHz boost clock. The Cinebench R20 results show 17,187 multi-core and 2,426 single-core, while the older R15 test yields 4,916 multi-core and 327 single-core.

The GPU’s average benchmark score of 17,588 places it at the 61st percentile, with nearest rivals including the AMD Radeon Pro 560 (17,551, delta 0.2 percent), NVIDIA GeForce RTX 4060 (17,639, delta -0.3 percent), AMD Radeon HD 7790 (17,666, delta -0.4 percent), and AMD Radeon Pro 460 (17,509, delta 0.5 percent). The combined percentile for this CPU+GPU pairing is 77, which reflects a system where the CPU vastly outperforms the GPU in relative terms. The combined percentile is a weighted measure, and the substantial gap between the CPU’s 93rd percentile and the GPU’s 61st percentile pulls the overall score down from what the CPU alone would suggest.

Balance and Bottleneck

The benchmark data paints a clear picture of a system with significant component imbalance. The CPU, at the 93rd percentile, is a top-tier mobile processor capable of handling the most demanding multi-threaded workloads. The GPU, at the 61st percentile, is a mid-range integrated solution. In any workload that relies heavily on graphics processing, the GPU will be the limiting factor.

Evidence from the FPS scaling, or lack thereof, is absent since no measured FPS data exists. However, the benchmark scores indicate that in CPU-bound scenarios, such as physics calculations or data compression, the system will perform exceptionally well. The PassMark physics score of 2,926 and the data compression score of 515,143 demonstrate strong CPU throughput. Conversely, in GPU-bound workloads like 3D rendering or gaming at high resolutions, the system will be severely constrained by the GPU’s 8.909 TFLOPS of compute power.

The memory architecture reinforces this bottleneck. The CPU supports dual-channel DDR5 with a bandwidth of 102.4 GB/s, but the GPU shares this memory pool. In gaming scenarios, the shared memory bandwidth can create additional stalls, as the GPU cannot access dedicated high-speed VRAM. The system is therefore balanced for productivity tasks that favor CPU performance but unbalanced for graphics-intensive applications.

The 3DMark Steel Nomad DX12 score of 480 is a clear indicator of the GPU’s limits in modern game engines. This score, when compared to the CPU’s high Cinebench scores, suggests that in gaming, the GPU will consistently be the performance ceiling. The delta between the CPU’s percentile (93) and the GPU’s percentile (61) is 32 percentage points, which is a substantial gap that defines the system’s character.

CPU Analysis

The Intel Core Ultra 7 255HX is a 20-core, 20-thread processor with a base clock of 2.40 GHz and a boost clock of 5.20 GHz. It is built on the Arrow Lake architecture, specifically Arrow Lake-HX, and manufactured on a 3 nm process by TSMC. The chip contains 17,800 million transistors on a 243 mm² die, with a power envelope rated at 55 W TDP.

The cache hierarchy is substantial, with 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. This large cache pool supports the CPU’s high single-thread performance, as evidenced by the Cinebench R23 single-core score of 2,163. The 5.20 GHz boost clock is among the highest for mobile processors, and the unlocked multiplier allows for enthusiast-level tuning if the laptop chassis permits.

In PassMark tests, the CPU scores 48,234 in multi-thread, 4,562 in single-thread, 160,624 in floating-point math, and 127,126 in integer math. The data encryption score of 39,499 and extended instructions score of 41,247 indicate robust security and SIMD processing capabilities. The find prime numbers score of 400 is relatively low, which may reflect the specific instruction set optimization for this workload. The random string sorting score of 62,591 shows strong memory access patterns.

These scores translate to real-world performance that is excellent for software development, video editing, and 3D rendering. The multi-core performance, as shown by the Cinebench R23 score of 32,612, is competitive with desktop processors from a few generations prior, making this CPU a powerful mobile workstation component. The single-thread performance, demonstrated by the PassMark single-thread score of 4,562, ensures snappy responsiveness in everyday tasks and strong performance in lightly-threaded applications.

Usage Scenarios

For high-refresh gaming, the combination is not ideal. The GPU’s 61st percentile performance and lack of dedicated VRAM will likely limit frame rates in competitive titles to playable but not high-refresh levels at 1080p. The CPU’s strong single-thread performance ensures that frame pacing will be consistent, but the GPU is the bottleneck.

Streaming is a mixed scenario. The CPU’s 20 cores and 20 threads, with a 93rd percentile ranking, can handle the encoding workload efficiently. The PassMark data encryption score of 39,499 suggests that hardware-accelerated encoding will be smooth. However, the integrated GPU may struggle to render the game at acceptable quality while the CPU handles the encoding, potentially requiring lower in-game settings.

Video editing is a strong use case for this system. The Cinebench R23 multi-core score of 32,612 means that rendering timelines and exporting videos will be fast. The GPU’s compute capabilities, demonstrated by the Geekbench OpenCL score of 18,602, can assist with effects and transitions, though the shared memory may limit the complexity of GPU-accelerated effects.

3D rendering is similarly CPU-favorable. The PassMark floating-point math score of 160,624 indicates excellent numerical throughput, which is essential for rendering algorithms. The GPU’s 8.909 TFLOPS can handle viewport rendering and previews, but final frame rendering will be CPU-dominated, which is a strength of this processor.

Software development benefits greatly from this CPU. The multi-thread performance allows for fast compilation times, and the single-thread performance ensures that code editors and build tools remain responsive. The 30 MB L3 cache helps with large codebases, and the 20 threads can handle parallel builds efficiently.

Student and office work will be more than adequately served. The single-thread score of 4,562 ensures that word processors, spreadsheets, and web browsers operate smoothly. The CPU’s high percentile ranking means that even the most demanding productivity applications will run without issue, and the integrated GPU is sufficient for basic graphical tasks.

Who Should Build It

This configuration targets users who prioritize CPU-intensive workloads in a laptop form factor. Gamers at 1080p with modest settings expectations, particularly in esports titles, will find the Radeon 780M sufficient, but those seeking high-refresh or high-fidelity gaming should look elsewhere. The system is better suited to content creators who work with video editing or 3D rendering, where the CPU’s 93rd percentile performance delivers professional-level throughput.

Software developers will find this pairing compelling, as the 20 cores and 20 threads accelerate compilation and testing, while the integrated GPU provides adequate display output without the power draw of a discrete GPU. Students in engineering or computer science fields will benefit from the CPU’s performance in simulation and data analysis tools. Small business workstations that require heavy data processing, as indicated by the PassMark data compression score of 515,143, will also see excellent performance.

The system is not designed for users who need high-end gaming performance or GPU-accelerated workflows like machine learning training. The GPU’s 61st percentile ranking and lack of tensor cores make it unsuitable for those tasks. Instead, the target user is one who needs maximum CPU power in a laptop and is willing to accept the limitations of integrated graphics.

Build Overview

The AMD Radeon 780M is an integrated GPU based on the RDNA 3.0 architecture, sharing the Phoenix chip with the CPU package. It has a TDP of 15 W, which is a fraction of the CPU’s 55 W TDP, and the combined system power draw remains moderate for a laptop. The GPU’s system-shared memory means that the total system RAM is used for both CPU and GPU tasks.

The combined percentile of 77 reflects a system that is above average overall, but the disparity between the CPU’s 93rd percentile and the GPU’s 61st percentile is the defining characteristic. This is a laptop class build, as indicated by the buildClass field, and the Intel BGA 2114 socket confirms that the CPU is soldered to the motherboard, limiting upgradability. The system is best described as a CPU-first mobile workstation with integrated graphics.

Upgrade Path and Platform

The Intel Core Ultra 7 255HX uses the Intel BGA 2114 socket, which is a ball-grid array design that is soldered to the motherboard. This means that the CPU cannot be upgraded without replacing the entire motherboard, which is not a practical option in a laptop form factor. The production status is listed as Active, so the processor is currently in production, but its mobility class limits future upgrades.

The CPU supports DDR5 memory in a dual-channel configuration, and the memory bus provides a bandwidth of 102.4 GB/s. The system memory is shared with the GPU, so adding more RAM will also increase the available memory for the integrated GPU. The PCIe interface is Gen 5 with 20 lanes for the CPU, which allows for high-speed storage devices and potentially external GPU enclosures, though the laptop chassis would need to support such connectivity.

The GPU has a TDP of 15 W and does not require any power connectors, as it is an integrated part of the system. The CPU has a TDP of 55 W, and the total system power draw is modest, meaning that a standard laptop power adapter should provide sufficient headroom. There is no suggested PSU provided for this combination, which is typical for integrated GPU configurations.

A sensible next upgrade for this system would be to maximize the system memory, as the GPU relies on shared memory for its frame buffer. Increasing the memory capacity and ensuring it runs at the highest supported speed can improve GPU performance. Beyond that, the only significant upgrade path is to a new laptop with a discrete GPU, as the CPU and GPU are both tightly integrated into the current platform.
