Q: How does the frame rate scale when moving from 1080p to 1440p?

A: Moving from 1920x1080 to 2560x1440 at the same settings reduces performance by approximately 37% at Low settings (104 to 66 FPS) and 37% at Medium settings (73 to 46 FPS). The High preset shows a 37% drop as well (57 to 36 FPS), while Ultra shows a 35% reduction (37 to 24 FPS).

Q: What is the CPU's single-threaded performance in this configuration?

A: The AMD Ryzen 7 7700X scores 1090 in 3DMark single-thread, 1987 in Cinebench R23 single-core, and 2289 in Geekbench single-core. These scores place it well above average, but Fortnite's frame rates are constrained by the GPU regardless of the CPU's capabilities.

GPU Role

The Intel Arc B370 is the dominant factor in this system's Fortnite performance, and the data indicates it is a severely underpowered component for this game. The GPU's 3DMark Steel Nomad score of 1184 places it at the 5th percentile among all tested GPUs, with its nearest rivals being the ATI Mobility Radeon HD 5570 (score 1186, 0.2% faster), the ATI Radeon HD 5770 (score 1190, 0.5% faster), and the AMD Radeon HD 7650M (score 1192, 0.7% faster). This places the Arc B370 in territory occupied by integrated and entry-level discrete graphics solutions from over a decade ago.

The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, which seems generous on paper, but the hardware resources behind those clocks are minimal. The Arc B370 has only 1280 shading units, 40 texture mapping units, and 20 render output units. Its pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s, with FP32 performance of 6.144 TFLOPS. These figures, when combined with the 25 W TDP and system-shared memory architecture, explain the weak results in Fortnite.

The memory situation is particularly problematic for gaming. The Arc B370 uses system-shared memory with system-dependent bandwidth, meaning it relies entirely on the host system's DDR5 memory rather than dedicated VRAM. In Fortnite, where texture streaming and memory bandwidth are critical, this shared memory arrangement creates a bottleneck that the CPU's dual-channel 83.2 GB/s memory bandwidth cannot overcome. The GPU's 3 nm Panther Lake chip and Xe3-LPG architecture are modern, but the implementation as an IGP-class part with only 20 ROPs severely limits fill-rate-bound scenarios common in Fortnite's building and rendering mechanics.

Resolution Scaling

The measured frame rates reveal a GPU-bound system where resolution scaling follows predictable patterns. At 1920x1080, the average frame rates range from 104 FPS at Low settings down to 37 FPS at Ultra. Increasing to 2560x1440 drops these figures to 66 FPS at Low and 24 FPS at Ultra, representing roughly a 35-37% reduction across all settings. At 3840x2160, the numbers collapse further to 35 FPS at Low and 13 FPS at Ultra.

This scaling pattern is characteristic of a system where the GPU is saturated at every resolution. The consistent percentage drops between resolutions indicate that the GPU's compute and memory resources are fully utilized even at 1080p, leaving no headroom for higher resolutions. The CPU's role in this scaling is minimal; a CPU-bound system would show smaller frame rate differences between resolutions because the CPU would be the limiting factor regardless of pixel count.

The 4K results are particularly telling. At 3840x2160, even the Low preset only manages 35 FPS, and the Ultra preset drops to 13 FPS. These numbers are far below playable thresholds and demonstrate that the Arc B370 simply does not have the pixel throughput or memory bandwidth to handle 4K rendering in Fortnite. The system-shared memory configuration likely compounds this issue, as the GPU competes with the CPU for the same memory bandwidth at higher resolutions where more data needs to be moved.

Measured FPS Breakdown

At 1920x1080, the measured results show a wide spread across settings. The Low preset delivers 104 FPS average, which is the only configuration in the entire dataset to exceed 100 FPS. The Medium preset achieves 73 FPS average with a minimum of 62 FPS and maximum of 84 FPS, providing a consistent experience above the 60 FPS threshold. The High preset drops to 57 FPS average, while the Ultra preset falls to 37 FPS average.

Moving to 2560x1440, the frame rates decrease across the board. The Low preset averages 66 FPS, which remains above 60 FPS but with less headroom. The Medium preset averages 46 FPS with minimum and maximum values of 39 and 53 FPS respectively. The High preset manages 36 FPS, and the Ultra preset drops to 24 FPS. None of the 1440p configurations provide a consistent 60+ FPS experience.

At 3840x2160, the results are uniformly poor. The Low preset averages 35 FPS, the Medium preset averages 25 FPS with minimum and maximum values of 21 and 28 FPS, the High preset averages 19 FPS, and the Ultra preset averages 13 FPS. These numbers are below playable thresholds for a competitive Battle Royale game, where frame rates below 60 FPS are generally considered insufficient for smooth gameplay.

The gap between Low and Ultra settings is substantial at every resolution. At 1080p, the difference between Low and Ultra is 67 FPS (104 to 37), representing a 64% reduction. At 1440p, the gap is 42 FPS (66 to 24), a 64% reduction. At 4K, the gap is 22 FPS (35 to 13), again a 63% reduction. This consistent ratio suggests that the settings presets scale uniformly across resolutions, with each step from Low to Medium to High to Ultra adding a similar computational burden.

How This Combo Ranks

The combination of the AMD Ryzen 7 7700X and Intel Arc B370 ranks 2517th out of 2740 tested combos in Fortnite, placing it in the bottom 8% of all systems tested. This ranking is almost entirely attributable to the GPU, which sits at the 5th percentile among all GPUs with an average benchmark score of 1184. The CPU, by contrast, ranks at the 85th percentile with an average benchmark score of 35909, meaning the processor is capable of far more than the graphics solution can deliver.

The pairing creates an extreme imbalance. The Ryzen 7 7700X's nearest CPU rivals include the AMD Ryzen 7 PRO 5845 (0.3% faster), Intel Core 7 250H (0.5% faster), AMD Ryzen AI 7 PRO 350 (0.5% faster), and Intel Core Ultra 9 185H (0.7% faster). These are all modern processors in the same performance class, demonstrating that the CPU is competitive with contemporary hardware. The GPU, however, is comparable to the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, and AMD FirePro M2000 — all legacy parts from previous generations.

This combination rank of 2517 out of 2740 suggests that most other tested systems, even those with older or weaker CPUs, outperform this pairing in Fortnite because they are paired with more capable graphics solutions. The data indicates that the Arc B370's IGP-class design, with its 25 W TDP and system-shared memory, is fundamentally mismatched with a desktop high-performance CPU like the Ryzen 7 7700X for this game.

Settings Recommendations

For this combination, the measured data clearly indicates that 1920x1080 with the Medium preset provides the best overall experience. This configuration delivers 73 FPS average with a minimum of 62 FPS and maximum of 84 FPS, keeping the frame rate above 60 FPS for the majority of gameplay while offering better visual quality than the Low preset. The minimum of 62 FPS is particularly important for a competitive Battle Royale title, as it suggests the frame rate will rarely dip below the playable threshold.

At 1920x1080 with the Low preset, the system achieves 104 FPS average, which provides the smoothest experience in terms of raw frame rate. However, the visual quality sacrifice may not be worth the additional 31 FPS over Medium, especially given that Fortnite's art style and visibility can benefit from higher quality settings. The High preset at 1080p drops to 57 FPS average, which is below the 60 FPS threshold and likely to cause noticeable stuttering in fast-paced combat. The Ultra preset at 37 FPS is not recommended for any gameplay scenario.

At 2560x1440, only the Low preset achieves an average above 60 FPS at 66 FPS, but this comes with the lowest visual quality settings. The Medium preset at 46 FPS is borderline playable but will struggle in intense moments. At 3840x2160, no preset achieves playable frame rates, with the best result being 35 FPS at Low settings. Users targeting 1440p or 4K should consider lowering the resolution to 1080p to maintain acceptable performance.

CPU Role

The AMD Ryzen 7 7700X provides substantial processing power that is largely untapped in this pairing. The CPU features 8 cores and 16 threads based on the Zen 4 architecture, with a base clock of 4.50 GHz and boost clock of 5.40 GHz. It has 32 MB of shared L3 cache, 1 MB of L2 cache per core, and 64 KB of L1 cache per core. The 105 W TDP and 5 nm process node from TSMC contribute to its strong benchmark scores.

In synthetic benchmarks, the Ryzen 7 7700X scores 19088 in Cinebench R23 multicore and 1987 in single-core, along with 12451 in Geekbench multicore and 2289 in single-core. Its 3DMark results show 8859 for 16 threads, 7057 for 8 threads, 4074 for 4 threads, 2112 for 2 threads, and 1090 for single-thread. PassMark results include 35686 for multithread and 4190 for single-thread. These scores place the CPU at the 85th percentile of all CPUs, indicating it is well above average for the current hardware landscape.

In Fortnite, however, the CPU's role is diminished because the GPU cannot keep up with the processor's output. The measured frame rates across all resolutions and settings are constrained by the Intel Arc B370's limited pixel throughput and memory bandwidth. The CPU's 16 threads and high boost clock are capable of feeding far more frames than the GPU can render, but this capability is wasted in this configuration. The system-shared memory arrangement compounds the issue, as the GPU's memory access pattern may create additional latency that the CPU cannot mitigate.

The data suggests that this CPU would perform significantly better in Fortnite when paired with a more capable GPU. The 85th percentile CPU ranking versus the 5th percentile GPU ranking illustrates a fundamental mismatch. For users with this CPU, the benchmark results indicate that upgrading the graphics solution would yield substantial frame rate improvements in Fortnite, as the CPU has ample headroom to support a more powerful GPU.
