Fortnite

The AMD Ryzen 5 9600X is a 6-core, 12-thread desktop processor built on the Zen 5 architecture (Granite Ridge) using TSMC’s 4 nm process. It runs on the AMD Socket AM5 platform and supports DDR5 memory in a dual-channel configuration. The CPU’s base clock is 3.90 GHz, with a boost clock of 5.40 GHz. Like many modern desktop chips, it includes Radeon integrated graphics and has an unlocked multiplier, which allows for overclocking. The processor has a 65 W TDP, making it a relatively efficient part for a desktop CPU. Its cache layout consists of 80 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB L3 cache, which is standard for this class of processor. In terms of memory bandwidth, the CPU supports up to 89.6 GB/s, and it offers PCIe Gen 5 connectivity with 24 lanes from the CPU itself. The chip was released in August 2024 with a launch MSRP of $279.

For Fortnite, the CPU’s role is somewhat secondary to the GPU in many scenarios, but its thread management and clock speeds matter for frame pacing. The 9600X’s high boost clock of 5.40 GHz is beneficial for games that rely on single-thread performance, and Fortnite is known to scale reasonably well with strong single-core throughput. The benchmark results for this CPU show a single-thread score of 1253 in 3dmark and 2183.5 in Cinebench R23 single-core, which are solid figures for a mainstream chip. Multi-threaded performance is also respectable, with a Cinebench R23 multicore score of 17528.5 and a 3dmark max threads score of 7590. In Passmark, the CPU achieves a multithread score of 30027 and a single-thread score of 4570. These numbers place the Ryzen 5 9600X in the 81st percentile of all CPUs, indicating that it outperforms a large majority of processors on the market. Its average benchmark score is 29713.

When compared to its nearest rivals, the 9600X is effectively in a tight cluster. The AMD Ryzen 7 PRO 5755GE scores 29656, which is a 0.2% difference. The AMD Ryzen 7 7840H scores 29868, a -0.5% delta. The AMD Ryzen 7 5800XT scores 29879, a -0.6% delta. The AMD Ryzen 7 8845HS scores 29955, a -0.8% delta. All four rivals are within a single percentage point of the 9600X, meaning that in synthetic benchmarks, these processors are virtually interchangeable. For Fortnite, this implies that the CPU is unlikely to be the bottleneck when paired with a low-end GPU, as the frame rates will be constrained by the graphics solution rather than the processor’s ability to feed frames.

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

The Ryzen 5 9600X offers 6 cores and 12 threads, which is more than enough for a game like Fortnite that typically utilizes fewer than 8 threads effectively. The high boost clock of 5.40 GHz is the standout feature for gaming, as Fortnite’s engine benefits from rapid single-thread execution for physics, game logic, and draw call processing. In the measured data, the CPU’s impact is visible in the way frame rates scale with resolution. At 1920x1080 with Low settings, the game hits 104 FPS on average, which suggests that the CPU is capable of driving high frame rates when the GPU is not overwhelmed. The 3dmark 2-thread score of 2456 and 4-thread score of 4649 indicate that the processor has strong low-thread performance, which aligns with Fortnite’s typical thread usage. The Cinebench R23 single-core score of 2183.5 further supports this, as it shows the CPU can handle demanding single-threaded workloads without issue.

The 65 W TDP and 4 nm process node mean the CPU runs efficiently, but that is less relevant to in-game performance than raw clock speed. The 32 MB shared L3 cache is ample for game data, and the DDR5 memory support with dual-channel configuration provides the bandwidth needed for high-FPS scenarios. At 1080p Low, the average FPS of 104 suggests that the CPU is not the limiting factor in that configuration, because the GPU is a low-end integrated part that would typically struggle to exceed that frame rate. However, it is also possible that the CPU is still holding back performance slightly, as the 9600X has been shown to push frame rates much higher in other contexts. The benchmark data shows that the CPU’s percentile rank is 81, so it is a strong processor overall, but in this specific pairing, the GPU is the clear bottleneck.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 5 9600X and the Intel Arc B370 ranks 2517 out of 2740 tested combos in Fortnite. This places it in the bottom 8% of all configurations, which is a poor result for a system that includes a modern 6-core CPU. The rank reflects the GPU’s limitations more than the CPU’s capabilities, as the Intel Arc B370 is an integrated graphics solution with a very low benchmark score. The combo’s rank is heavily influenced by the GPU’s 5th percentile ranking among all GPUs, which drags the overall system performance down. In practice, this means that while the CPU is in the 81st percentile, the GPU is in the 5th percentile, leading to a massive mismatch in performance potential.

The fact that this combo ranks so low is not surprising given the GPU’s specs, but it does highlight that the CPU is massively overqualified for the graphics solution. In games like Fortnite, which can be CPU-bound at low resolutions, the 9600X might still show its strength, but the overall frame rates are capped by the Arc B370. The combo rank of 2517 out of 2740 means that almost every other tested system will outperform this one, particularly at higher resolutions where the GPU is stressed further. For a user who already owns this CPU, upgrading the GPU would be the logical path to improve Fortnite performance, as the CPU is not the limiting factor in this pairing.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear trend of decreasing performance as resolution increases, which is typical for a GPU-bound scenario. At 1920x1080 with Low settings, the average FPS is 104. Moving to 2560x1440 at Low settings, the average drops to 66, which is a 36.5% reduction. At 3840x2160 with Low settings, the average further drops to 35, which is a 66.3% reduction from the 1080p figure. This pattern indicates that the GPU is the dominant limiting factor, as frame rates fall dramatically with the increased pixel count. If the CPU were the bottleneck, we would expect to see similar FPS across resolutions until the GPU becomes saturated, but here the scaling is almost linear with pixel count.

The same trend holds across other settings. At Medium settings, 1080p yields 73 FPS, 1440p yields 46 FPS, and 4K yields 25 FPS. At High settings, the numbers are 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K. At Ultra settings, the figures are 37 FPS at 1080p, 24 FPS at 1440p, and 13 FPS at 4K. In every case, the performance drops by roughly 30-40% when moving from 1080p to 1440p, and then by another 40-50% when moving from 1440p to 4K. This is consistent with a GPU that has a very low fill rate and limited shading units. The Intel Arc B370 has only 20 ROPs and a pixel rate of 48.00 GPixel/s, which is insufficient for high-resolution gaming. The texture rate of 96.00 GTexel/s and FP32 throughput of 6.144 TFLOPS are also very low for modern standards.

The resolution scaling analysis reveals that the CPU is not the bottleneck in any of these scenarios. Even at 1080p Low, where the CPU has the most headroom, the FPS of 104 is modest and likely limited by the GPU’s ability to render frames. The Ryzen 5 9600X could easily push Fortnite to 200+ FPS at 1080p Low with a discrete GPU, but the Arc B370 cannot keep up. The data suggests that users should play at 1080p if they want playable frame rates, as higher resolutions will result in sub-30 FPS performance at most settings.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of this combo’s performance in Fortnite. At 1920x1080, the lowest resolution tested, the results are as follows: Low settings produce an average of 104 FPS, Medium settings produce an average of 73 FPS with a minimum of 62 and a maximum of 84, High settings produce an average of 57 FPS, and Ultra settings produce an average of 37 FPS. These numbers show that even at the lowest resolution, the system cannot maintain high refresh rates on higher presets. The jump from Low to Medium is a 29.8% performance hit, while going from Medium to High is a 21.9% hit, and from High to Ultra is a 35.1% hit. This indicates that the GPU struggles with the increased shading and texture work at higher settings.

At 2560x1440, the performance drops significantly. Low settings yield an average of 66 FPS, Medium settings yield 46 FPS with a minimum of 39 and a maximum of 53, High settings yield 36 FPS, and Ultra settings yield 24 FPS. These figures are roughly 60% of the 1080p results, reflecting the increased pixel count. The minimum FPS of 39 at Medium settings shows that frame pacing can be inconsistent, which could lead to stutter in fast-paced gameplay. At 1440p, only Low settings are consistently above 60 FPS, and even then, the 66 FPS average is close to the edge.

At 3840x2160, the performance becomes marginal for playability. Low settings produce an average of 35 FPS, Medium settings produce 25 FPS with a minimum of 21 and a maximum of 28, High settings produce 19 FPS, and Ultra settings produce 13 FPS. None of these averages are above 60 FPS, and even the highest setting (Low) is below the 30 FPS threshold that is often considered the minimum for playable gaming. The minimum FPS of 21 at Medium settings indicates that there are significant frame drops, which would be noticeable in a competitive game like Fortnite. The data clearly shows that 4K is not a viable resolution for this combo, regardless of settings.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B370 is an integrated GPU based on the Xe3-LPG architecture, built on Intel’s 3 nm process. It has 1280 shading units, 40 texture mapping units, and 20 render output units. The GPU also includes 10 ray tracing cores, which support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The base clock is 300 MHz, and the boost clock is 2400 MHz. The memory configuration is “System Shared,” meaning it uses the system’s DDR5 memory rather than dedicated VRAM. The memory bus width and bandwidth are also system-dependent, which means performance can vary based on the CPU and motherboard. The GPU’s TDP is 25 W, and it has no power connectors, as it is an IGP (integrated graphics processor).

The GPU’s performance in Fortnite is extremely limited. The 3dmark Steel Nomad DX12 score of 1184 puts it in the 5th percentile of all GPUs, meaning it is slower than 95% of graphics cards. Its nearest rivals include the ATI Mobility Radeon HD 5570 with a score of 1186 (a -0.2% delta), the ATI Radeon HD 5770 with a score of 1190 (a -0.5% delta), the AMD Radeon HD 7650M with a score of 1192 (a -0.7% delta), and the AMD FirePro M2000 with a score of 1168 (a 1.4% delta). These are all older, low-end GPUs, which illustrates that the Arc B370 is comparable to hardware from over a decade ago. The FP32 throughput of 6.144 TFLOPS and texture rate of 96.00 GTexel/s are far below what is needed for modern gaming at high settings.

In Fortnite, the GPU’s lack of dedicated VRAM is a significant issue, as the game’s textures and geometry must be stored in system memory, which is slower and shared with the CPU. The system-dependent memory bandwidth means that the Arc B370’s performance can be inconsistent, but the measured FPS data shows that it is consistently low. The boost clock of 2400 MHz is relatively high for an integrated GPU, but the low number of shading units and ROPs severely limits its fill rate. The pixel rate of 48.00 GPixel/s is insufficient for high resolutions, and the texture rate of 96.00 GTexel/s is too low for high-detail textures. The GPU’s TDP of 25 W is also indicative of its limited capabilities, as it draws very little power but also delivers very little performance.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience for this combo in Fortnite is at 1920x1080 with Low settings, which produces an average of 104 FPS. This is the only configuration in the data that exceeds 100 FPS, and it provides a smooth, responsive experience that is suitable for competitive play. The next best option is 1080p Medium, which yields 73 FPS with a minimum of 62 and a maximum of 84. This is also playable, but the minimum FPS of 62 is close to the 60 FPS threshold, and frame drops could occur in intense moments. For users who prefer higher visual quality, 1080p High at 57 FPS is borderline, but it may feel less smooth than the lower presets.

At 2560x1440, the only recommended setting is Low, which produces 66 FPS. This is playable, but the frame rate is lower than the 1080p Low result, and the visual improvement may not be worth the performance cost. Medium at 1440p yields 46 FPS, which is below the 60 FPS target but still playable for casual gaming. High and Ultra at 1440p are not recommended, as they produce 36 and 24 FPS respectively, which will feel sluggish. At 3840x2160, none of the settings are recommended, as even Low produces only 35 FPS, and the minimum FPS at Medium is 21, which is too low for a smooth experience. The data suggests that users should prioritize frame rate over resolution and settings, as the GPU is too weak to handle higher loads.

In summary, the best experience per the measured rows is 1080p Low, which offers the highest average FPS and likely the most consistent frame pacing. For users who want better visuals, 1080p Medium is a reasonable compromise, but they should be aware of potential frame drops. The combo is not suitable for 1440p or 4K gaming at higher settings, and even Low settings at those resolutions may not provide a satisfactory experience. The CPU is capable of much more, but the GPU is the limiting factor that dictates the settings recommendations.
