Fortnite

Fortnite with the Intel Core Ultra 5 245 and Intel Arc B370 produces a highly constrained experience, with the integrated graphics solution acting as the definitive bottleneck across all tested settings. The measured frame rates indicate that this combo is positioned for low-resolution, low-detail play, and even then, the results hover near the edge of playability. The data shows a clear hierarchy: resolution and settings adjustments yield predictable FPS shifts, but the ceiling is firmly set by the Arc B370’s capabilities. This analysis breaks down the measured results, contextualizes them against the CPU and GPU specifications, and answers common questions about this pairing.

Resolution Scaling

The measured FPS data reveals a steep drop-off as resolution increases from 1920x1080 to 3840x2160, which is a classic sign of a GPU-bound scenario. At 1920x1080 with Low settings, the combo achieves an average of 104 FPS. Moving to 2560x1440 at Low settings, that average falls to 66 FPS, a 36.5% reduction. At 3840x2160 with Low settings, the average plummets to 35 FPS, which is a 66.3% drop from the 1080p result. This pattern confirms that the Intel Arc B370’s rendering throughput is the limiting factor; the CPU is not the constraint here, as the frame rate scales inversely with pixel count.

The scaling between resolutions is not linear, which further emphasizes the GPU bottleneck. From 1080p Low to 1440p Low, the FPS drops by 38 frames. From 1440p Low to 4K Low, the FPS drops by 31 frames. The percentage loss is larger going from 1080p to 1440p (36.5%) than from 1440p to 4K (47.0% of the 1440p value), but both steps show that each additional pixel carries a heavy cost. For High settings, the trend is similar but with lower absolute numbers: 57 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K. The 4K High result is unplayable for competitive play, and even 1440p High (36 FPS) is below the threshold for smooth action.

What does this say about the limiting component? The CPU, an Intel Core Ultra 5 245 with 14 cores and a boost clock of 5.10 GHz, has ample headroom in this scenario. The GPU’s 6.144 TFLOPS of FP32 performance and 48.00 GPixel/s pixel rate are simply insufficient to keep up with higher resolutions. The data suggests that players should treat 1080p as the only viable resolution, and even then, settings above Medium will push the average below 60 FPS. The 4K results (19 FPS High, 25 FPS Medium, 35 FPS Low, 13 FPS Ultra) are all below 40 FPS, indicating that 4K is not a realistic target for this combo in Fortnite.

GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, fabricated on a 3 nm process. Its role in this combo is pivotal, and the benchmark data shows that its performance profile is the primary determinant of the measured FPS. The GPU has 1280 shading units, 40 texture mapping units, and 20 raster output units, with a base clock of 300 MHz and a boost clock of 2400 MHz. These specifications translate to a texture rate of 96.00 GTexel/s and a pixel rate of 48.00 GPixel/s, figures that are modest by discrete GPU standards.

The memory configuration is a critical limitation: the Arc B370 uses "System Shared" memory, meaning it relies on the system’s DDR5 RAM rather than dedicated VRAM. The bandwidth is listed as "System Dependent," which in practice means the GPU shares the CPU’s memory bandwidth of 102.4 GB/s. This shared memory arrangement often leads to performance degradation under load, especially at higher resolutions where memory pressure increases. The measured FPS data supports this: at 4K Ultra, the average FPS drops to 13, and at 4K High it is 19, suggesting that both compute and memory bandwidth are saturated.

The GPU’s percentile ranking versus all GPUs is 5, which places it in the bottom 5% of tested hardware. Its nearest rivals include the ATI Mobility Radeon HD 5570 (avg score 1186, deltaPct -0.2%), the ATI Radeon HD 5770 (avg score 1190, deltaPct -0.5%), and the AMD Radeon HD 7650M (avg score 1192, deltaPct -0.7%). These are legacy parts from over a decade ago, which underscores how limited the Arc B370 is for modern gaming. The GPU’s 3DMark Steel Nomad DX12 score is 1184, a figure that aligns with its low percentile ranking. In Fortnite, this translates to playable frame rates only at 1080p Low (104 FPS) and 1080p Medium (73 FPS), with 1080p High (57 FPS) being borderline.

The clock speeds are worth noting in context. The 2400 MHz boost clock is respectable for an IGP, but the low core count (1280 shading units) and low pixel rate limit its real-world output. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which means it can run modern APIs, but the hardware lacks the throughput to leverage them effectively at higher settings. The 25 W TDP is very low, which is typical for integrated graphics, but it also means the GPU is not designed for sustained high-load gaming. The measured FPS data shows that even at 1080p Medium, the minimum FPS is 62, which is acceptable, but at 1440p Medium, the minimum drops to 39, indicating inconsistent frame pacing under load.

FAQ

Q: Can this combo run Fortnite at 1080p with playable frame rates?

A: Yes, but only at lower settings. The measured data shows 104 FPS at 1080p Low, 73 FPS at 1080p Medium, and 57 FPS at 1080p High. These are all above 30 FPS, with Low and Medium exceeding 60 FPS. However, 1080p Ultra drops to 37 FPS, which is below the 60 FPS target for smooth competitive play.

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

A: The Arc B370 has a 3DMark Steel Nomad DX12 score of 1184, which is nearly identical to the ATI Mobility Radeon HD 5570 (1186, -0.2%), the ATI Radeon HD 5770 (1190, -0.5%), and the AMD Radeon HD 7650M (1192, -0.7%). It outperforms the AMD FirePro M2000 (1168, +1.4%) by a small margin. These rivals are all legacy parts, indicating the Arc B370’s performance is comparable to hardware from over a decade ago.

Q: Is the Intel Core Ultra 5 245 the bottleneck in this combo?

A: No. The CPU has 14 cores and a boost clock of 5.10 GHz, and its benchmark scores (e.g., Cinebench R23 multicore score of 32924) place it in the 90th percentile of all CPUs. The frame rate scaling with resolution indicates the GPU is the limiting factor. The CPU’s nearest rivals include the AMD Ryzen 7 PRO 5755G (-0.4% delta) and the Intel Core i5-14600K (+0.8% delta), showing it is a capable processor.

Q: What is the best resolution and settings combo for this system?

A: Based on the data, 1920x1080 with Low settings is the optimal choice, yielding 104 FPS average. If visual quality is a priority, 1080p Medium (73 FPS) is still playable, but 1080p High (57 FPS) may cause occasional dips below 60 FPS. Higher resolutions like 1440p and 4K should be avoided, as the average FPS drops below 66 at any setting.

Q: How does this combo rank among all tested combos in Fortnite?

A: The combo ranks 2517 out of 2740 tested combinations, placing it in the bottom 8.2% of all systems. This low ranking is directly attributable to the GPU’s weak performance, as the CPU is in the top 10% of all processors.

Q: Is the Arc B370’s system-shared memory a problem for Fortnite?

A: Yes. The memory bandwidth is "System Dependent," and the GPU uses the same DDR5 memory as the CPU, which has a bandwidth of 102.4 GB/s. This shared arrangement often causes performance drops under load, particularly at higher resolutions. The measured FPS at 4K (13-35 FPS across settings) suggests that memory bandwidth is a contributing factor to the poor scaling.

Measured FPS Breakdown

The measured FPS data provides a full picture of this combo’s performance across three resolutions and four settings. At 1920x1080, the results are the most favorable. Low settings yield an average of 104 FPS, which is the highest score in the entire dataset. Medium settings produce 73 FPS average, with a minimum of 62 FPS and a maximum of 84 FPS. High settings drop to 57 FPS average, while Ultra settings are the worst at 37 FPS. The spread from Low to Ultra is 67 FPS, which indicates that settings have a significant impact at 1080p, but the GPU still manages to stay above 30 FPS even at Ultra.

At 2560x1440, the performance degrades noticeably. Low settings average 66 FPS, which is still playable but 38 FPS lower than 1080p Low. Medium settings average 46 FPS, with a minimum of 39 FPS and a maximum of 53 FPS. High settings drop to 36 FPS, and Ultra settings fall to 24 FPS. The 1440p results show that only Low settings come close to the 60 FPS threshold, and even then, the margin is thin. The minimum FPS at 1440p Medium (39) suggests that frame pacing may be inconsistent, which could lead to stutter during intense combat scenes.

At 3840x2160, the results are largely unplayable for a fast-paced game like Fortnite. Low settings average 35 FPS, Medium settings average 25 FPS (with a minimum of 21 and maximum of 28), High settings average 19 FPS, and Ultra settings average 13 FPS. The 4K data shows that no setting combination achieves a 30 FPS average except for Low, and even that is marginal. The gap between 1080p Low (104 FPS) and 4K Low (35 FPS) is 69 FPS, a 66% reduction. This confirms that the Arc B370’s pixel throughput is insufficient for 4K rendering, regardless of settings.

The data also reveals a pattern: the difference between Low and Ultra settings narrows as resolution increases. At 1080p, the gap is 67 FPS (104 vs 37). At 1440p, the gap is 42 FPS (66 vs 24). At 4K, the gap is 22 FPS (35 vs 13). This indicates that at higher resolutions, the GPU becomes so saturated that settings adjustments have diminishing returns. Players seeking higher FPS should prioritize lowering resolution over lowering settings, as the former has a larger impact.

CPU Role

The Intel Core Ultra 5 245 is a desktop processor from the Core Ultra Series 2, based on the Arrow Lake architecture and fabricated on a 3 nm process. It features 14 cores and 14 threads, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz. The CPU has a 24 MB shared L3 cache, with per-core L1 (192 KB) and L2 (3 MB) caches. Its TDP is 65 W, and it supports DDR5 memory in a dual-channel configuration with a bandwidth of 102.4 GB/s. The CPU is unlocked? No, the multiplier is locked, but its performance is not the issue in this combo.

In terms of benchmark scores, the Core Ultra 5 245 performs strongly. Its Cinebench R23 multicore score is 32924, and its single-core score is 4648. The PassMark multithread score is 38706, and the single-thread score is 4394. These numbers place the CPU in the 90th percentile of all CPUs, with an average benchmark score of 48995. Its nearest rivals include the AMD Ryzen 7 PRO 5755G (avg score 49196, deltaPct -0.4%), the AMD Ryzen 9 7900 (avg score 49228, deltaPct -0.5%), the Intel Xeon Gold 5318H (avg score 48698, deltaPct +0.6%), and the Intel Core i5-14600K (avg score 48618, deltaPct +0.8%). This puts the Core Ultra 5 245 in the same performance class as these established CPUs, with differences of less than 1% in average benchmark score.

In Fortnite, the CPU’s role is to feed the GPU with draw calls and physics calculations. With 14 cores and a 5.10 GHz boost clock, the Core Ultra 5 245 is well-equipped to handle these tasks. The measured FPS data shows that the CPU is not the limiting factor, as frame rates scale with resolution and settings in a way that is characteristic of GPU-bound scenarios. For example, at 1080p Low, the CPU can push 104 FPS, but at 4K Low, the FPS drops to 35, which is not a CPU limitation. The CPU’s high single-thread performance (4648 in Cinebench R23 single-core) is particularly relevant for Fortnite, which is known to be sensitive to single-thread performance. However, even this strength cannot overcome the GPU’s weakness.

The CPU’s integrated graphics, an Arc Xe-LPG Graphics 64EU, is separate from the discrete Arc B370 used in this combo. The CPU’s memory support for DDR5 and its 102.4 GB/s bandwidth are shared with the GPU, which can create contention in memory-intensive scenarios. But the CPU’s compute capabilities are more than sufficient for Fortnite’s requirements. The data suggests that pairing this CPU with a more powerful discrete GPU would yield significantly higher frame rates, but that is outside the scope of this analysis.

How This Combo Ranks

The combo of the Intel Core Ultra 5 245 and the Intel Arc B370 ranks 2517 out of 2740 tested combinations in Fortnite. This places it in the bottom 8.2% of all systems, a position that is overwhelmingly influenced by the GPU’s weak performance. The CPU, by contrast, ranks in the 90th percentile of all CPUs, but the combo ranking reflects the overall system’s gaming capability, which is capped by the Arc B370.

To contextualize this ranking, consider the CPU’s nearest rivals in benchmark terms. The AMD Ryzen 7 PRO 5755G, AMD Ryzen 9 7900, Intel Xeon Gold 5318H, and Intel Core i5-14600K all have average benchmark scores within 1% of the Core Ultra 5 245. If any of these CPUs were paired with the Arc B370, the combo ranking would likely be similar, because the GPU is the bottleneck. The GPU’s nearest rivals—the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M—are all legacy parts with similar or slightly lower 3DMark scores. This means the combo is effectively performing at the level of a system from the early 2010s, despite having a modern CPU.

The combo rank of 2517 out of 2740 means that 223 combos perform worse. These would likely feature even older or weaker integrated graphics or CPUs. However, the vast majority of tested combos (over 91%) outperform this pairing in Fortnite. The data suggests that this combo is suitable only for casual play at low settings and 1080p resolution. For competitive Fortnite, which often requires 144 FPS or higher, this system falls far short. The measured FPS at 1080p Low (104 FPS) is the best-case scenario, and even that is below the 144 FPS target. At 1080p Medium (73 FPS) or High (57 FPS), the system is better suited for non-competitive play.

In summary, the combo ranking reflects a fundamental mismatch between the CPU’s high-end capabilities and the GPU’s entry-level performance. The Core Ultra 5 245 is a strong processor, but the Arc B370’s integrated graphics design—with system-shared memory, a 25 W TDP, and a 5th percentile GPU ranking—holds the entire system back. Players considering this combo should expect to play Fortnite at 1080p with Low or Medium settings, and they should not expect to achieve high frame rates at higher resolutions or settings. The data is clear: this is a low-end gaming setup, and its ranking in the bottom 8.2% of combos confirms that assessment.
