Fortnite

The AMD Ryzen 7 5800X paired with the Intel Arc B390 produces a highly constrained gaming experience in Fortnite, where the graphics solution acts as the primary performance limiter across all tested resolutions. The dataset provides a clear picture of how this combination scales from 1080p up to 4K, with frame rates that range from playable at lower settings to severely compromised at higher presets. This analysis examines the measured FPS results, the role of each component, and how this combo ranks among the 2,740 tested configurations.

Resolution Scaling

The measured FPS data for Fortnite reveals a steep performance drop as resolution increases, which is characteristic of a system where the GPU is the dominant bottleneck. At 1920x1080 with Low settings, the combo achieves an average of 115 FPS, which drops to 73 FPS at 2560x1440 and further to 39 FPS at 3840x2160. This represents a 36.5% reduction from 1080p to 1440p, and a 66.1% reduction from 1080p to 4K at the same Low preset. The scaling pattern indicates that the Intel Arc B390 simply cannot sustain higher frame rates as pixel count increases, regardless of the CPU’s capabilities.

Moving to Medium settings, the frame rate trajectory follows a similar shape but at lower absolute values. At 1080p, the average is 81 FPS with a minimum of 69 FPS and a maximum of 93 FPS. At 1440p, the average falls to 51 FPS, with a minimum of 44 FPS and a maximum of 59 FPS. At 4K, the average drops to 27 FPS, with a minimum of 23 FPS and a maximum of 31 FPS. The delta between 1080p and 1440p is 37%, while the delta between 1080p and 4K is 66.7%. These percentages closely mirror the Low preset scaling, reinforcing that resolution is the primary variable controlling performance, with the GPU being the limiting factor.

High settings show an even more constrained picture. At 1080p, the average FPS is 63. At 1440p, it drops to 40, and at 4K, it reaches just 21. The relative drop from 1080p to 1440p is 36.5%, and from 1080p to 4K it is 66.7%. This consistency across Low, Medium, and High presets suggests that the GPU’s pixel throughput ceiling is being hit at each resolution, and that settings changes have a secondary effect compared to resolution changes.

Ultra settings deliver the lowest performance of all. At 1080p, the average is 41 FPS. At 1440p, it falls to 26 FPS, and at 4K, it bottoms out at 14 FPS. The drop from 1080p to 1440p is 36.6%, and from 1080p to 4K is 65.9%. These results indicate that Ultra is nearly unplayable at 4K, with average frame rates in the mid-teens. Even at 1080p, 41 FPS is below the threshold for smooth competitive play in a battle royale title.

The data shows that the limiting component is unequivocally the GPU. The CPU, an AMD Ryzen 7 5800X with 8 cores and 16 threads, has ample compute resources, but the Intel Arc B390, with its system-shared memory and integrated graphics architecture, cannot keep up with the demands of higher resolutions. The consistent percentage drops across all settings presets point to a fixed GPU bottleneck rather than any CPU-side constraint. For users targeting higher refresh rates, the only viable options are 1080p with Low or Medium settings, as 1440p and 4K require significant compromises.

CPU Role

The AMD Ryzen 7 5800X is a desktop processor from the 5000 series, built on the Zen 3 architecture with the codename Vermeer. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. The processor has a 32 MB L3 cache, along with 64 KB of L1 cache per core and 512 KB of L2 cache per core. It supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s. The CPU’s TDP is 105 watts, and it uses the AMD Socket AM4 interface. It is manufactured on a 7 nm process node by TSMC, with 4,150 million transistors on a die size of 74 mm².

In terms of synthetic benchmarks, the Ryzen 7 5800X posts strong multithreaded scores. In Cinebench R23, it achieves 15,476 points in multicore and 1,574.5 points in single-core. In Geekbench, it scores 11,036 in multicore and 2,032 in single-core. The 3DMark results show 7,586 points for 16 threads and 7,578 for max threads, while single-thread performance is 943 points. The PassMark multithread score is 27,732, with a single-thread score of 3,445. The CPU’s percentile versus all CPUs is 81, indicating it outperforms the majority of processors in the database.

For Fortnite specifically, the CPU’s role is to feed the GPU with draw calls and game logic. The Ryzen 7 5800X’s 8 cores and 16 threads are more than sufficient for a battle royale title, which typically scales well with multiple threads. The high boost clock of 4.70 GHz also helps in single-threaded scenarios, which are common in game physics and rendering commands. However, the measured FPS data shows that the CPU is not the limiting factor. At 1080p Low, the system reaches 115 FPS, which is a respectable number, but the GPU cannot push beyond that.

The nearest rivals to the Ryzen 7 5800X in terms of average benchmark score include the Intel Core Ultra 5 135H with a delta of 0.1%, the Intel Xeon Phi 7210 with a delta of -0.4%, and the Intel Core i5-13500HX with a delta of -0.5%. These comparisons show that the Ryzen 7 5800X sits in a competitive position relative to other processors, but none of these rivals would change the outcome in Fortnite because the GPU is the bottleneck.

The CPU’s memory support for DDR4 and dual-channel bandwidth of 51.2 GB/s is adequate for gaming. The 32 MB L3 cache helps with data reuse, but again, the GPU’s limitations overshadow any CPU advantage. In Fortnite, the data indicates that even a significantly weaker CPU could achieve similar frame rates with this GPU, as the system is constrained by the graphics solution. The Ryzen 7 5800X’s role is to provide headroom, which goes unused in most tested scenarios.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, with the chip codename Panther Lake. It is manufactured on a 3 nm process node by Intel, with a base clock of 300 MHz and a boost clock of 2500 MHz. The GPU has 1,536 shading units, 48 texture mapping units, and 24 raster output units. It also includes 12 ray tracing cores. The FP32 performance is 7.680 TFLOPS, and the FP16 performance is 15.36 TFLOPS with a 2:1 ratio. The pixel rate is 60.00 GPixel/s, and the texture rate is 120.0 GTexel/s. The TDP is 80 watts, and it uses system-shared memory, meaning there is no dedicated VRAM.

The memory configuration is entirely system-shared, with the type, bus width, and bandwidth all listed as system dependent. This is a significant limitation for gaming, as the GPU must compete with the CPU for memory bandwidth. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which are modern APIs. However, its benchmark score in 3DMark Steel Nomad DX12 is only 1,482, placing it in the 9th percentile versus all GPUs.

The nearest rivals to the Intel Arc B390 include the NVIDIA GeForce GT 520MX with a delta of 1.3%, the NVIDIA GeForce 800M with a delta of 1.5%, and the NVIDIA GeForce GT 625 OEM with a delta of 2.5%. These are all older, low-end mobile or OEM GPUs, which underscores the Arc B390’s position at the bottom of the performance hierarchy. The GPU’s average benchmark score of 1,482 is extremely low compared to dedicated graphics cards.

In Fortnite, the GPU’s limitations are evident across all settings. The system-shared memory means that increasing resolution or settings directly impacts memory bandwidth, which is already constrained. The 7.680 TFLOPS of FP32 compute is modest, and the 24 ROPs limit pixel fill rate, which is critical at higher resolutions. The measured FPS data shows that the GPU cannot maintain 60 FPS at 1080p on High settings, achieving only 63 FPS on Low. At 4K, even Low settings yield just 39 FPS, which is below acceptable playability.

The GPU’s boost clock of 2500 MHz is not enough to compensate for the lack of dedicated VRAM and the low number of shading units. The 48 TMUs and 24 ROPs are insufficient for modern game rendering at high resolutions. The 12 ray tracing cores are present, but enabling such features would likely crater performance further, though no ray tracing data is provided. The GPU’s TDP of 80 watts is low, indicating it is designed for power efficiency rather than raw performance.

The data shows that the Intel Arc B390 is the definitive bottleneck in this combo. The CPU has significant headroom, but the GPU cannot translate that into frame rates. For Fortnite, the GPU’s role is to render frames, and it fails to do so at competitive levels beyond 1080p Low. The system-shared memory is a particular weakness, as it creates latency and bandwidth issues that dedicated GPUs avoid.

How This Combo Ranks

The AMD Ryzen 7 5800X + Intel Arc B390 combination is ranked 2,417 out of 2,740 tested combos in Fortnite. This places it in the bottom 12% of all configurations, which aligns with the GPU’s low percentile ranking. The combo’s rank reflects the severe performance limitations imposed by the Arc B390, despite the CPU’s strong synthetic benchmarks.

In the context of the database, this ranking means that the vast majority of other combos deliver higher frame rates in Fortnite. The combo’s position is driven entirely by the GPU, as the CPU is in the 81st percentile versus all CPUs. The GPU, in contrast, is in the 9th percentile versus all GPUs, which drags the overall combo rank down significantly.

The nearest rivals to the CPU include the Intel Core Ultra 5 135H and the Intel Core i5-13500HX, both of which have similar average scores. However, if paired with a better GPU, those combos would rank much higher in Fortnite. The data shows that the combo rank is not a reflection of CPU capability but rather a direct consequence of GPU performance.

When comparing to other combos in the same game, the 2,417th rank out of 2,740 means there are 323 combos that perform worse. Those likely involve even older or more integrated GPUs. However, the vast majority of combos outperform this pairing, making it a poor choice for Fortnite at any resolution above 1080p Low.

The combo’s ranking also has implications for settings. At 1080p Low, the system achieves 115 FPS, which is playable, but the rank suggests that most other combos can achieve similar or better frame rates at higher settings. The data indicates that this combo is best suited for esports-style play at the lowest settings, where the CPU’s strength can partially offset the GPU’s weakness.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the resolution target. At 1920x1080, the Low preset delivers an average of 115 FPS, which is the highest measured frame rate for this system. This is the recommended preset for competitive play, as it provides a smooth experience close to 120 Hz. The Medium preset at 1080p delivers 81 FPS, which is still playable but may not be smooth enough for fast-paced battles. The High preset at 63 FPS is borderline, and the Ultra preset at 41 FPS is not recommended for any gameplay scenario.

At 2560x1440, the Low preset achieves 73 FPS, which is the only playable option at this resolution. Medium drops to 51 FPS, High to 40 FPS, and Ultra to 26 FPS. For users who prioritize resolution over frame rate, 1440p Low is viable, but the drop from 1080p Low is significant. The data suggests that 1080p is the sweet spot for this combo.

At 3840x2160, the Low preset averages 39 FPS, which is below the threshold for smooth gameplay. Medium averages 27 FPS, High averages 21 FPS, and Ultra averages 14 FPS. None of these are recommended for actual gameplay, as the frame rates are too low for a battle royale where reaction time matters. The GPU’s system-shared memory and low compute power make 4K impractical.

The best overall experience, according to the measured rows, is 1920x1080 with Low settings. This configuration yields the highest average FPS of 115 and avoids the stutter-prone lower frame rates seen at higher resolutions. For those who want better visual fidelity, the Medium preset at 1080p provides a 30% reduction in FPS but still maintains an average above 60. However, given the GPU’s limitations, the Low preset is the safest recommendation for consistent performance.

The data shows no benefit to raising settings beyond Medium at any resolution, as the frame rate drops become increasingly steep. The Ultra preset should be avoided entirely, as it produces the lowest FPS at every resolution. The combo’s 2,417th rank out of 2,740 combos underscores that this is a low-end configuration, and settings should be tuned to the minimum to achieve acceptable frame rates.
