Fortnite

# CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9850X3D is an 8-core, 16-thread processor built on the Zen 5 architecture (Granite Ridge) using a 4 nm process at TSMC. Its base clock of 4.70 GHz and boost clock of 5.60 GHz position it as a high-frequency desktop part, with 96 MB of shared L3 cache providing substantial on-die storage for game data. This processor is part of the 9000 series, launched in January 2026, and it supports DDR5 memory in a dual-channel configuration with 89.6 GB/s of bandwidth. The CPU's benchmark scores reinforce its strength: it achieves a Cinebench R23 multi-core score of 22,807 and a single-core score of 2,228, while PassMark multi-thread and single-thread scores reach 41,318 and 4,704, respectively. Its percentile ranking of 92 among all CPUs indicates it sits in the top 8% of processors tested, a dominant position for gaming workloads.

In Fortnite, the CPU's role becomes evident when examining the measured FPS across settings. At 1920x1080 with Low settings, the combo reaches 104 FPS average, which is the highest score in the entire measured dataset. This suggests that at lower resolutions and reduced graphical loads, the Ryzen 7 9850X3D's combination of high clocks and large cache effectively feeds the GPU with enough data to maximize frame rates. The CPU's nearest rival, the Intel Core i9-14900, has an average benchmark score of 58,115, which is 0.5% lower than the 9850X3D's 58,386 average. This close competition in synthetic benchmarks translates to real-world gaming where the 9850X3D's 8 cores are sufficient for Fortnite's engine, which typically scales well with strong single-thread performance. The processor's 120 W TDP and unlocked multiplier suggest headroom for enthusiasts, though the measured data shows no overclocking scenarios were tested.

The CPU's impact becomes more apparent at lower settings where the GPU is less stressed. At 1080p Low, the FPS jumps to 104, a 1.8x increase over 1080p High at 57 FPS. This pattern indicates that the CPU is capable of pushing well beyond what the integrated GPU can render, but the bottleneck shifts based on settings. The presence of 16 threads allows for background tasks and game logic to run concurrently without stalling, which is critical in a Battle Royale with many players and dynamic environments. The Ryzen 7 9850X3D's 96 MB L3 cache is particularly beneficial for Fortnite's asset streaming, as frequently accessed textures and geometry can reside closer to the cores, reducing latency. Benchmark results show the CPU's PassMark data compression score of 474,501 and integer math score of 123,140, both indicating robust processing power that handles game logic, physics, and network code efficiently. However, the measured FPS reveals that even this powerful CPU cannot overcome the GPU's limitations at higher resolutions, with 4K Ultra dropping to just 13 FPS. This suggests the CPU is not the limiting factor in most scenarios; instead, the integrated graphics hold back the system's potential.

# Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases from 1080p to 4K. At 1920x1080 with Low settings, the combo achieves 104 FPS average. Moving to 2560x1440 at the same settings drops the average to 66 FPS, a 36.5% reduction. At 3840x2160, the FPS falls further to 35, representing a 66.3% decrease from the 1080p baseline. This scaling behavior indicates that the Intel Arc B370 is the primary limiting factor, as the CPU's processing power remains constant across resolutions while the GPU's rendering workload expands exponentially with pixel count.

The same trend holds across other settings. For High settings, 1080p yields 57 FPS, 1440p drops to 36 FPS (36.8% reduction), and 4K falls to 19 FPS (66.7% reduction). Medium settings show 73 FPS at 1080p, 46 FPS at 1440p (37% reduction), and 25 FPS at 4K (65.8% reduction). Ultra settings display the most dramatic drops: 37 FPS at 1080p, 24 FPS at 1440p (35.1% reduction), and 13 FPS at 4K (64.9% reduction). The consistency of these percentage reductions across all settings strongly suggests that the GPU's fill rate and pixel throughput are the bottleneck, not the CPU or memory subsystem.

The data also shows that the GPU's pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are insufficient for high-resolution gaming. At 4K (3840x2160), the total pixel count is 8.3 million, and the GPU must process this volume 60 times per second for smooth gameplay, requiring a fill rate of approximately 498 MPixel/s. Even at Low settings, the Arc B370 manages only 35 FPS, indicating it is operating near its theoretical limits. The FP32 performance of 6.144 TFLOPS further constrains the system, as modern game engines rely heavily on shader computations that scale with resolution. The resolution scaling pattern confirms that upgrading the GPU would yield significant FPS improvements, while the CPU has ample headroom to support a more powerful graphics solution.

# How This Combo Ranks

The combo of AMD Ryzen 7 9850X3D and Intel Arc B370 ranks 3,414 out of 3,700 tested combinations in Fortnite, placing it in the bottom 7.7% of all configurations. This low ranking is directly attributable to the GPU's weak performance, as evidenced by its 5th percentile ranking among all graphics cards. The CPU, in contrast, ranks in the 92nd percentile, demonstrating a massive imbalance between the two components. In practical terms, this means the system is severely GPU-limited, with the CPU's capabilities largely untapped during gameplay.

The nearest rival GPUs in benchmark scores are all older, low-end parts: the ATI Mobility Radeon HD 5570 (1,186 score, 0.2% higher), ATI Radeon HD 5770 (1,190 score, 0.5% higher), AMD Radeon HD 7650M (1,192 score, 0.7% higher), and AMD FirePro M2000 (1,168 score, 1.4% lower). This places the Arc B370 in the same performance tier as integrated graphics from over a decade ago, which explains why the combo ranks so poorly in a modern game like Fortnite. The game's release in 2017 means it has evolved to demand more from GPUs, and the Arc B370 cannot keep pace.

The ranking also reflects the CPU-GPU pairing's overall efficiency. While the Ryzen 7 9850X3D provides excellent single-thread performance (PassMark single-thread score of 4,704) and multi-thread capability (PassMark multi-thread score of 41,318), these strengths are wasted when the GPU can only produce 13 to 104 FPS depending on settings. The measured FPS at 1080p Low (104 FPS) is the only scenario where the system approaches playable frame rates, and even then, it falls short of the 144 FPS commonly desired for competitive gaming. The rank of 3,414 out of 3,700 indicates that most other tested combinations deliver better overall performance, making this pairing suitable only for low-resolution, low-settings gaming or non-gaming workloads where the CPU's power can be fully utilized.

# GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) built on the Panther Lake chip using a 3 nm process at Intel. Its architecture, Xe3-LPG, is designed for mobile and integrated solutions, with 1,280 shading units, 40 texture mapping units, and 20 raster operations units. The GPU operates at a base clock of 300 MHz and boosts to 2,400 MHz, with memory being system shared, meaning it relies on the host system's DDR5 RAM rather than dedicated VRAM. The memory bus width and bandwidth are listed as "System Shared" and "System Dependent," respectively, indicating that performance varies based on the CPU's memory configuration. The GPU's FP32 throughput is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS (2:1 ratio), and it features 10 ray tracing cores for hardware-accelerated ray tracing.

In Fortnite, the GPU's limitations are stark. Its 3DMark Steel Nomad DX12 score of 1,184 places it in the 5th percentile of all GPUs, and its nearest rivals are all older, low-end parts from the HD 5000 and HD 7000 series. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are minimal by modern standards, and the 25 W TDP confirms this is a low-power integrated solution. The GPU's DirectX 12 Ultimate support (12_2) is a positive feature, as it enables modern rendering techniques, but the hardware's raw compute power is insufficient to leverage these features at playable frame rates.

The measured FPS data confirms the GPU is the bottleneck across all resolutions and settings. At 1080p Low, the GPU achieves 104 FPS, which is the highest in the dataset, but this still falls short of high-refresh-rate gaming expectations. At 1080p Ultra, the FPS drops to 37, a 64.4% reduction, showing that the GPU cannot handle high graphical loads. The lack of dedicated VRAM further compounds the issue, as system memory bandwidth (89.6 GB/s for the CPU) is shared between the CPU and GPU, creating potential contention. The GPU's 2,400 MHz boost clock is respectable for an integrated part, but the low core count (1,280 shading units) and limited ROPs (20) constrain its ability to fill pixels and process geometry efficiently. For Fortnite, which is not a graphically demanding game by modern standards, the Arc B370 still struggles, particularly at 4K where even Low settings yield only 35 FPS.

# Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across three resolutions and four settings levels. At 1920x1080, the lowest resolution tested, the system achieves its best results. Low settings produce an average of 104 FPS, which is the only configuration that exceeds 100 FPS. Medium settings yield 73 FPS average, with a range of 62 to 84 FPS, while High settings drop to 57 FPS. Ultra settings are the most demanding, producing only 37 FPS average. This pattern shows a clear inverse relationship between graphical fidelity and frame rate, with a 64.4% reduction from Low to Ultra.

Moving to 2560x1440, the performance drops significantly across all settings. Low settings average 66 FPS, which is 36.5% lower than the 1080p Low result. Medium settings average 46 FPS, with a range of 39 to 53 FPS, while High settings produce 36 FPS. Ultra settings at 1440p yield only 24 FPS, which is 35.1% lower than the 1080p Ultra result. The reduction percentages are consistent across all settings, reinforcing that the GPU's pixel fill rate is the primary constraint. At 1440p, the total pixel count is 3.7 million, which is 56% more than 1080p, and this additional workload directly impacts performance.

At 3840x2160, the highest resolution tested, the system struggles to maintain playable frame rates. Low settings average 35 FPS, which is 66.3% lower than 1080p Low and 47% lower than 1440p Low. Medium settings average 25 FPS, with a range of 21 to 28 FPS, while High settings produce 19 FPS. Ultra settings are the worst, yielding only 13 FPS, which is 64.9% lower than the 1080p Ultra result. The 4K resolution has 8.3 million pixels, which is 2.25 times more than 1440p and 4.5 times more than 1080p, and the GPU's fill rate simply cannot keep up. The minimum FPS values for Medium settings at 4K (21 FPS) indicate that even the best-case frame times are below 30 FPS, making the game effectively unplayable at this resolution. Overall, the measured FPS data shows that this combo is only viable at 1080p with Low or Medium settings, and even then, the frame rates are modest by modern standards.
