Fortnite

The AMD Ryzen 7 9700X paired with the Intel Arc B370 produces a very constrained gaming experience in Fortnite, with the measured frame rates indicating a severe bottleneck. The data places this combination at rank 2517 out of 2740 tested combos, placing it in the bottom 8% of all configurations. The Arc B370, operating as an integrated GPU with system-shared memory, is clearly the limiting factor here, as the Ryzen 7 9700X provides substantial processing headroom that the graphics solution cannot utilize. This analysis walks through the measured FPS data to explain what these numbers mean for playability and how the components interact.

Resolution Scaling

The measured FPS data reveals a stark relationship between resolution and performance. At 1080p with Low settings, the combo achieves 104 FPS, which drops to 66 FPS at 1440p and further to 35 FPS at 4K. This represents a 66% reduction in frame rate when moving from 1080p to 4K at Low settings. The scaling pattern is consistent across all settings: High settings produce 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K, showing a similar proportional decline.

The nature of this scaling suggests that the limiting component is the GPU, not the CPU. When resolution increases, the pixel fill rate demand grows exponentially, and the Arc B370's modest specifications — 20 ROPs and a 48.00 GPixel/s pixel rate — cannot keep pace. If the CPU were the bottleneck, we would expect frame rates to remain relatively flat across resolutions, since the CPU's workload stays roughly constant regardless of pixel count. Instead, the consistent drop at each resolution step indicates the GPU's rendering capacity is being saturated.

The difference between Low and Ultra settings at each resolution further emphasizes the GPU limitation. At 1080p, Low yields 104 FPS while Ultra yields only 37 FPS — a 64% performance penalty for enabling higher visual fidelity. At 4K, this gap shrinks proportionally: Low produces 35 FPS while Ultra drops to 13 FPS. The fact that even at 1080p Ultra the frame rate falls below 40 FPS suggests that the Arc B370's shading units (1280) and TMUs (40) are simply insufficient for Fortnite's higher-quality rendering paths.

Interestingly, the transition from 1080p to 1440p at Low settings shows a 38 FPS drop (104 to 66), while the transition from 1440p to 4K shows a 31 FPS drop (66 to 35). This non-linear scaling indicates that at lower resolutions, the GPU is closer to keeping up with the CPU's frame delivery, but as resolution climbs, the GPU becomes increasingly overwhelmed. The data strongly suggests that for this combo, resolution is the primary determinant of playability, with 1080p being the only viable option for acceptable frame rates.

FAQ

Q: What frame rate can I expect at 1080p with Medium settings?

A: The measured data shows an average of 73 FPS at 1080p Medium, with a minimum of 62 FPS and a maximum of 84 FPS. This is the most balanced setting in the measured range, providing a playable experience above the 60 FPS threshold.

Q: Is this combo capable of 4K gaming in Fortnite?

A: Benchmark results indicate no. At 4K, the highest average FPS achieved is 35 with Low settings, and that drops to 19 FPS on High and 13 FPS on Ultra. These numbers fall well below acceptable playability standards, and even the minimum frame rates at 4K Medium (21 FPS) confirm the GPU cannot handle 4K rendering.

Q: How does the Arc B370 compare to its nearest GPU rivals?

A: The Arc B370's average benchmark score is 1184, placing it at the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 (score 1186, 0.2% faster), ATI Radeon HD 5770 (score 1190, 0.5% faster), and AMD Radeon HD 7650M (score 1192, 0.7% faster). These are all legacy or low-power parts, confirming the Arc B370 sits at the bottom of the GPU performance spectrum.

Q: Which settings preset provides the best experience at 1440p?

A: At 2560x1440, Low settings produce 66 FPS average, which is the only preset that exceeds 60 FPS. Medium drops to 46 FPS, High to 36 FPS, and Ultra to 24 FPS. For smooth gameplay at this resolution, Low settings are the only viable option.

Q: Does the Ryzen 7 9700X's performance contribute positively to this game's results?

A: The CPU benchmarks show strong performance — a Cinebench R23 multi-core score of 20485 and single-core of 2211 — but the measured FPS data shows the GPU limits the combo. The CPU's percentile rank versus all CPUs is 86, and its average benchmark score of 37943 places it near the Intel Core i9-14901E (0.1% difference). The CPU has ample headroom that the Arc B370 cannot exploit.

Q: What is the minimum frame rate guarantee at 1080p?

A: The only settings preset with recorded minimum FPS is Medium at 1080p, showing 62 FPS minimum against a 73 FPS average. For other presets, only averages are available, but the Low preset's 104 FPS average suggests a minimum likely above 60 FPS, while Ultra's 37 FPS average indicates minimums that would fall well below playable levels.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel's 3 nm process. Its specifications are modest: 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores. The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, but crucially, its memory is "System Shared" with "System Dependent" bandwidth. This means the GPU relies on the CPU's DDR5 memory, creating a significant bandwidth constraint for a game like Fortnite that benefits from fast memory access.

The GPU's compute capabilities are limited, with FP32 performance of 6.144 TFLOPS and FP16 at 12.29 TFLOPS (2:1 ratio). These numbers are extremely low by modern discrete GPU standards, explaining why the measured frame rates at all resolutions and settings remain modest. The 3DMark Steel Nomad DX12 benchmark score of 1184 places the Arc B370 at the 5th percentile of all GPUs, confirming its position at the very bottom of the performance hierarchy.

For Fortnite specifically, the GPU's limitations manifest in the scaling behavior observed. The game's battle royale mode requires consistent rendering of large open environments, physics interactions, and multiple players simultaneously. The Arc B370's 20 ROPs limit pixel throughput, directly impacting resolution scaling, while the 40 TMUs restrict texture fill rate, affecting higher settings that rely on detailed textures. The system-shared memory architecture means that as resolution increases, the memory bandwidth pressure grows, further degrading performance.

The GPU's thermal and power characteristics are notably different from discrete solutions: its TDP is just 25 W, and it uses no power connectors, fitting as an IGP (Integrated Graphics Processor). This explains why the GPU is fundamentally limited — it operates within the power envelope of a laptop or compact desktop, not a dedicated graphics card. The boost clock of 2400 MHz is respectable for an iGPU, but the underlying hardware resources are simply too sparse to deliver competitive gaming performance in a demanding title like Fortnite.

How This Combo Ranks

The combination of the AMD Ryzen 7 9700X and Intel Arc B370 ranks 2517 out of 2740 tested combos in Fortnite, placing it in the bottom 8.1% of all configurations. This ranking is heavily influenced by the GPU's position at the 5th percentile, while the CPU sits at the 86th percentile. The massive disparity between CPU and GPU capabilities creates an imbalanced system where the processor has far more performance than the graphics solution can utilize.

Examining the CPU's nearest rivals provides context: the Intel Core i9-14901E scores 37911 (0.1% lower), the AMD Ryzen AI 9 HX 370 scores 37904 (0.1% lower), and the Intel Core 5 211E scores 37829 (0.3% lower). These comparisons show the Ryzen 7 9700X is a top-tier processor in synthetic benchmarks, yet when paired with the Arc B370, the gaming results fall far below what the CPU alone would suggest. This demonstrates that combo rankings in gaming are predominantly determined by the GPU, not the CPU.

The GPU's nearest rivals in its own benchmark rankings include the ATI Mobility Radeon HD 5570 (1186, 0.2% higher), ATI Radeon HD 5770 (1190, 0.5% higher), and AMD Radeon HD 7650M (1192, 0.7% higher). These are all GPUs from the early 2010s or low-power mobile parts, underscoring the Arc B370's extremely low position. When such a weak GPU is paired with a high-end CPU, the resulting combo rank is inevitably poor, as the measured FPS data confirms.

The combo rank of 2517 out of 2740 suggests that nearly 92% of all tested combinations deliver better Fortnite performance. This is a critical finding for anyone evaluating this specific pairing — the data clearly indicates that the Arc B370 drags the entire system down, and the Ryzen 7 9700X's substantial processing power (evidenced by its 20485 Cinebench R23 multi-core score) goes largely unused in this game.

Settings Recommendations

Based on the measured FPS data, the only settings presets that provide a consistently playable experience are at 1080p. At this resolution, Low settings deliver 104 FPS average, which is the only preset across all resolutions and settings that exceeds 100 FPS. Medium settings at 1080p produce 73 FPS with a minimum of 62 FPS, ensuring frame times stay above the critical 60 FPS threshold even during intense gameplay moments.

For players who prioritize visual quality over raw frame rate, 1080p High settings offer 57 FPS average, which is borderline playable but may suffer from occasional dips during heavy action sequences. The Ultra preset at 1080p, with its 37 FPS average, is not recommended because it falls below the generally accepted 40 FPS minimum for smooth gameplay. At 1440p, the situation becomes more restrictive: Low settings are the only viable option at 66 FPS, while Medium drops to 46 FPS and High to 36 FPS.

At 4K, no settings preset provides playable performance. Even Low settings produce only 35 FPS, and the minimum frame rates recorded at Medium (21 FPS) suggest severe stuttering. The data indicates that this combo is strictly a 1080p gaming solution for Fortnite, with Medium settings representing the best balance between visual fidelity and smooth performance. Players who insist on higher resolutions would need to drastically reduce settings, but even then, the frame rates remain marginal at best.

Measured FPS Breakdown

The complete measured FPS dataset for Fortnite with the Ryzen 7 9700X and Arc B370 is as follows:

At 1920x1080, the four settings presets produce: Low at 104 FPS average, Medium at 73 FPS (minimum 62, maximum 84), High at 57 FPS, and Ultra at 37 FPS. The progression from Low to Ultra shows a 67 FPS drop, representing a 64% performance reduction when enabling the highest quality settings.

At 2560x1440, the results are: Low at 66 FPS, Medium at 46 FPS (minimum 39, maximum 53), High at 36 FPS, and Ultra at 24 FPS. The drop from Low to Ultra is 42 FPS, or 64%, maintaining the same proportional penalty as at 1080p. All presets except Low fall below the 60 FPS threshold.

At 3840x2160, the results are: Low at 35 FPS, Medium at 25 FPS (minimum 21, maximum 28), High at 19 FPS, and Ultra at 13 FPS. The drop from Low to Ultra is 22 FPS, or 63% — a consistent pattern across all resolutions. The minimum frame rate of 21 FPS at 4K Medium indicates that even the most conservative settings cannot maintain stable performance at this resolution.

Across all resolutions, the average FPS scales linearly with settings changes, but resolution changes produce non-linear effects. Moving from 1080p to 1440p at Low settings reduces FPS by 38 (104 to 66), while moving from 1440p to 4K reduces it by 31 (66 to 35). This suggests diminishing returns on FPS loss as resolution increases, but the absolute FPS numbers at 4K are so low that this scaling is irrelevant for practical gaming.

CPU Role

The AMD Ryzen 7 9700X is a high-end desktop processor based on the Zen 5 architecture, codenamed Granite Ridge. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. The CPU's cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache, providing 8,315 million transistors on a 70.6 mm² die manufactured on TSMC's 4 nm process.

In synthetic benchmarks, the Ryzen 7 9700X demonstrates strong performance: Cinebench R23 multi-core score of 20485 and single-core of 2211, Geekbench multi-core of 17906 and single-core of 3023, and 3DMark tests showing 9824 for 16 threads and 1280 for single-thread. Its PassMark multithread score of 37161 and single-thread of 4654 place it at the 86th percentile of all CPUs, with an average benchmark score of 37943. This places it in close competition with the Intel Core i9-14901E (0.1% difference) and AMD Ryzen AI 9 HX 370 (0.1% difference).

For Fortnite, the CPU's role is to handle game logic, physics, and the battle royale's many concurrent processes. The 8-core/16-thread configuration with a 5.50 GHz boost clock provides ample compute for these tasks. However, the measured FPS data shows that the GPU is the limiting factor — the CPU never becomes the bottleneck. This is evident because frame rates scale dramatically with resolution changes, which would not happen if the CPU were saturated.

The CPU's TDP of 65 W and support for DDR5 memory with 89.6 GB/s bandwidth indicate a modern, efficient design. Its 3DMark scores show strong scaling from 2 threads (2525) to 16 threads (9824), demonstrating good multi-threaded performance. In Fortnite, which typically uses fewer threads, the single-core performance of 1280 in 3DMark and 2211 in Cinebench R23 ensures the CPU can deliver frames quickly — but the Arc B370 simply cannot keep up with the CPU's frame delivery rate, resulting in the low FPS numbers observed.
