Fortnite

The Intel Core Ultra 7 265K paired with the Intel Arc B370 integrated graphics produces a very constrained gaming experience in Fortnite. The data shows a system where the graphics processor is the overwhelming bottleneck, struggling to maintain playable frame rates at most settings. This analysis breaks down the measured performance, the role of each component, and what the numbers indicate about this specific combination's capabilities.

Resolution Scaling

The measured FPS data reveals a steep and predictable performance cliff as resolution increases. At 1080p with Low settings, the combo achieves 104 FPS. This is the only configuration in the entire dataset that crosses the 100 FPS threshold. Dropping to 1440p at the same Low setting yields 66 FPS, a significant 36.5% reduction. Moving to 4K at Low produces only 35 FPS, which is a 66.3% drop from the 1080p Low result.

This scaling pattern is a classic indicator of a GPU-limited scenario. The Arc B370's compute resources are fully saturated at lower resolutions, and increasing the pixel count directly reduces the frame rate. The data shows the 1080p to 1440p transition for Medium settings: 73 FPS falls to 46 FPS, a 37% decrease. The 1440p to 4K transition for Medium settings shows 46 FPS falling to 25 FPS, a 45.7% decrease. The scaling is not perfectly linear, but the trend is consistent that every resolution bump costs a substantial fraction of performance.

The fact that the drop from 1080p to 1440p is similar in percentage to the drop from 1440p to 4K (roughly 37-46% per step) suggests the GPU is the limiting factor at all resolutions. If the CPU were the primary constraint, we would expect to see a smaller performance delta between 1080p and 1440p, as the CPU workload would not increase as dramatically with resolution. The data indicates the opposite, confirming that the Arc B370's rendering capabilities are the ceiling. The 4K Ultra result of just 13 FPS is a stark illustration of this limitation, representing a performance level that is entirely unsuitable for gameplay.

GPU Role

The Intel Arc B370 is not a discrete graphics card; it is an integrated graphics processor (IGP) based on the Xe3-LPG architecture. Its specifications paint a picture of a low-power solution designed for basic display output rather than high-performance gaming. The GPU's boost clock is listed at 2400 MHz, with a base clock of 300 MHz. The TDP is a mere 25 W, which is a fraction of what any dedicated gaming GPU would consume.

The memory configuration is crucial. The Arc B370 uses "System Shared" memory, meaning it has no dedicated VRAM. Its bandwidth is listed as "System Dependent," and the memory type is also "System Shared." This is a fundamental disadvantage for gaming. The GPU must share the system's DDR5 memory bandwidth with the CPU, which creates a severe bottleneck. The benchmark score for the GPU is a 3DMark Steel Nomad DX12 result of 1184. This score places the Arc B370 in the 5th percentile of all GPUs, indicating it is among the slowest.

Its nearest rivals in the benchmark database are all older, low-end parts: the ATI Mobility Radeon HD 5570 (score 1186, delta -0.2%), the ATI Radeon HD 5770 (score 1190, delta -0.5%), and the AMD Radeon HD 7650M (score 1192, delta -0.7%). The only listed rival it beats is the AMD FirePro M2000 (score 1168, delta 1.4%). These comparisons show the Arc B370's performance is on par with graphics solutions from more than a decade ago. In Fortnite, this translates to the low FPS figures observed. The 1080p Low result of 104 FPS is the best case, and it relies on the CPU doing a significant amount of work to keep the weak GPU fed. At higher settings, the GPU's limited shading units (1280), texture mapping units (40), and render output units (20) are simply overwhelmed.

How This Combo Ranks

In the context of all tested combinations for Fortnite, this specific pairing of the Core Ultra 7 265K and the Arc B370 ranks 2517 out of 2740 combos. This places it in the bottom 8% of all tested systems. The rank is exceptionally low, reflecting the GPU's severe performance limitations. It is important to consider that the CPU in this combo is a high-end desktop processor. The data suggests the processor's potential is almost entirely untapped because the integrated graphics cannot turn its computational power into high frame rates.

The combo rank is a direct result of the GPU's position in the overall GPU hierarchy. With a percentile ranking of 5, the Arc B370 is slower than 95% of all GPUs in the database. This is the dominant factor in the combo's rank. A comparison with the CPU's own ranking highlights the disparity: the Core Ultra 7 265K is in the 94th percentile of all CPUs. The data shows a pairing of a top-tier CPU with a bottom-tier GPU, resulting in a system that is only capable of very modest gaming performance. The 2517 rank out of 2740 combos is a quantitative confirmation that this is one of the weakest gaming configurations in the database for Fortnite.

CPU Role

The Intel Core Ultra 7 265K is a 20-core, 20-thread desktop processor based on the Arrow Lake architecture. It has a base clock of 3.90 GHz and a boost clock of 5.50 GHz. Its benchmark scores are formidable, including a Cinebench R23 multi-core score of 35850 and a single-core score of 2020. In the broader CPU benchmark database, it sits in the 94th percentile, with an average benchmark score of 70879. Its nearest rivals include the Intel Xeon 6511P (avg score 71051, delta -0.2%) and the Intel Core i7-14700KF (avg score 70163, delta 1%).

However, in this Fortnite pairing, the CPU's role is secondary. The data clearly shows that the Arc B370 is the limiting component. At 1080p Low, the system achieves 104 FPS. This is the highest result in the entire dataset and likely represents a scenario where the CPU is doing most of the work to maintain frame pacing. The CPU's high single-thread performance, evidenced by its 2713 Geekbench single-core score, is crucial for maintaining these higher frame rates. But the GPU's inability to render at higher resolutions or settings negates the CPU's potential.

The CPU's 20 cores and 30 MB of L3 cache are irrelevant for Fortnite's engine, which typically benefits most from strong single-core performance. The system's DDR5 memory support and dual-channel architecture provide the bandwidth that the integrated GPU must share, but this is still insufficient for demanding 3D workloads. The data implies that the CPU is a "paper" bottleneck in the sense that it is overpowered for the GPU. The measured FPS is a direct result of the GPU's limits, not the CPU's.

Settings Recommendations

Based on the measured FPS data, the only viable setting for a playable experience is Low. At 1920x1080, Low settings yield 104 FPS, which is smooth and responsive. The Medium preset at 1080p drops to 73 FPS, which is still playable but represents a large 29.8% performance hit for a graphical upgrade. The High preset at 1080p yields 57 FPS, which is marginal for a fast-paced game like Fortnite. The Ultra preset at 1080p produces 37 FPS, which is not recommended for competitive play.

At 2560x1440, the situation worsens. Low settings produce 66 FPS, which is the only 1440p preset that is consistently playable. The Medium preset at 1440p yields 46 FPS, which is borderline. High (36 FPS) and Ultra (24 FPS) are not recommended. At 3840x2160, no settings are recommended, as even Low produces only 35 FPS.

The best experience per the measured data is to play at 1920x1080 with Low settings. This provides the highest frame rate and the most consistent performance. If a user prefers visual quality over frame rate, the Medium preset at 1080p is the only other viable option. The data shows that the Ultra preset is a performance trap for this hardware, reducing FPS by more than half compared to Low. The recommendation is to prioritize frame rate and play at 1080p Low.

Measured FPS Breakdown

The following is the complete set of measured FPS data for this combo in Fortnite.

At 3840x2160:

• Low: 35 FPS average
• Medium: 25 FPS average, with a minimum of 21 FPS and a maximum of 28 FPS
• High: 19 FPS average
• Ultra: 13 FPS average

At 2560x1440:

• Low: 66 FPS average
• Medium: 46 FPS average, with a minimum of 39 FPS and a maximum of 53 FPS
• High: 36 FPS average
• Ultra: 24 FPS average

At 1920x1080:

• Low: 104 FPS average
• Medium: 73 FPS average, with a minimum of 62 FPS and a maximum of 84 FPS
• High: 57 FPS average
• Ultra: 37 FPS average

This data confirms that the system is only suitable for 1080p gaming at the lowest settings. The difference between Low and Ultra at 1080p is 67 FPS, a 64.4% drop. At 1440p, the difference between Low and Ultra is 42 FPS, a 63.6% drop. At 4K, the difference between Low and Ultra is 22 FPS, a 62.9% drop. The consistent percentage drop across resolutions when moving from Low to Ultra suggests that the GPU's fixed-function hardware (TMUs and ROPs) is the bottleneck, regardless of resolution. The system's performance is fundamentally limited by the Intel Arc B370's integrated graphics solution.
