Roblox

The Intel Core Ultra 5 245 paired with the Intel Arc B370 presents a peculiar case in the Roblox benchmark database. The CPU is a modern 14-core Arrow Lake part with a 90th percentile ranking among all tested processors, while the GPU is an integrated Arc B370 solution that sits at the 5th percentile, placing it in the company of legacy mobile parts from over a decade ago. This massive disparity is the defining characteristic of this combo, and the measured FPS data reflects the consequences of pairing a top-tier processor with a GPU that is fundamentally limited by its architecture and shared memory configuration. The data suggests a system where the CPU is almost never the bottleneck, yet the overall experience is still constrained by the graphics solution.

GPU Role

The Intel Arc B370 is the decisive limiting factor in this configuration. Its integrated nature is emphasized by its specifications: a base clock of 300 MHz, a boost clock of 2400 MHz, and system-shared memory. The memory bandwidth is listed as "System Dependent," meaning the GPU's performance is tied to the system's DDR5 memory and can be affected by other components accessing it. The 3DMark Steel Nomad DX12 score of 1184 places it at the 5th percentile, and its nearest rivals are all legacy parts like the ATI Mobility Radeon HD 5570 and the AMD Radeon HD 7650M. These are not modern gaming GPUs; they are entries from a much older era of mobile computing.

This low standing is reflected in the Roblox results. The GPU's 20 ROPs and 40 TMUs are extremely limited, and the 6.144 TFLOPS of FP32 compute is low by contemporary standards. The data implies that the GPU struggles to maintain high frame rates, particularly as resolution increases. At 1080p Low, it manages 154 FPS, but this drops to 101 FPS on Ultra. At 4K, the performance collapses, with the Ultra preset yielding only 38 FPS. The GPU is clearly the bottleneck at these higher resolutions, as the CPU is more than capable of feeding it frames. The shared memory architecture is likely a contributing factor, as the GPU must compete with the CPU for bandwidth.

The GPU's boost clock of 2400 MHz is relatively high, but it cannot compensate for the lack of dedicated hardware resources. The shading units (1280), texture units (40), and render output units (20) are the core of the problem; there simply are not enough of them to fill high-resolution frames at high settings. The data suggests that this GPU is designed for low-power, portable devices, not for sustained gaming at high resolutions. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s appear insufficient for the demands of 4K rendering, as evidenced by the average FPS dropping below 60 at that resolution across all settings.

CPU Role

The Intel Core Ultra 5 245 plays the role of an overqualified observer in this pairing. It is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 3 nm process. Its performance is demonstrated by a Cinebench R23 multi-core score of 32924 and a single-core score of 4648. This single-core performance is crucial for Roblox, which often relies on a few main threads. The CPU's boost clock of 5.10 GHz provides ample speed for such workloads. The data confirms the CPU's strength: it sits in the 90th percentile of all CPUs and its average benchmark score of 48995 is within 1% of the AMD Ryzen 9 7900 and the Intel Core i5-14600K.

Given this CPU's capability, it is unlikely to be the limiting factor in this combo's Roblox performance. The measured FPS data shows a clear pattern of degradation as resolution increases, which is a classic sign of a GPU bottleneck. At 1080p, the CPU can push the GPU to its limits, resulting in 154 FPS on Low. However, the fact that the FPS drops to 101 at 1080p Ultra and to 47 at 4K High suggests the GPU is overwhelmed, while the CPU still has headroom. The CPU's L3 cache is 24 MB shared, which is ample for game logic and physics calculations that Roblox requires.

The CPU's performance parity with its rivals, such as the Core i5-14600K, means that in a balanced system, you would expect similar gaming performance. However, the Arc B370's 5th percentile standing holds this CPU back. The CPU is ready to handle more frames, but the GPU cannot deliver them. The 14 threads are more than sufficient for Roblox, and the high boost clock ensures that the single-threaded tasks are processed quickly. The data implies that upgrading the GPU in this system would yield a massive performance improvement in Roblox, as the CPU would not be a barrier.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the combo's capabilities across different resolutions and settings. At 1920x1080, the combo performs best on Low, averaging 154 FPS. The Medium preset averages 140 FPS (with a min of 119 and max of 161), while High averages 124 FPS. The Ultra preset is the most demanding at this resolution, dropping the average to 101 FPS. This indicates that at 1080p, the system is capable of delivering playable frame rates, but the gap between Low and Ultra is significant, a 53 FPS difference.

Moving to 2560x1440, the performance drops considerably. The Low preset averages 103 FPS, while Medium averages 94 FPS (with a min of 80 and max of 108). High settings average 83 FPS, and Ultra falls to 67 FPS. This resolution is still playable, but the impact of the GPU's limitations becomes more apparent. The difference between Low and Ultra is now 36 FPS, showing that the GPU is starting to struggle with the increased pixel count.

At 3840x2160, the performance becomes marginal. The Low preset is the only one to average above 50 FPS, at 58 FPS. Medium averages 53 FPS (with a min of 45 and max of 61), while High drops to 47 FPS. Ultra is nearly unplayable, averaging only 38 FPS. The data shows a consistent and significant performance penalty for each step up in resolution. The transition from 1080p to 1440p reduces average FPS by roughly 33-40% across all settings. The transition from 1440p to 4K is even more severe, with a 43-44% reduction in average FPS. This scaling pattern is a strong indicator that the GPU is the primary bottleneck, as a CPU-bound system would not show such a dramatic drop when resolution increases.

How This Combo Ranks

The combo's overall rank in Roblox is 2774 out of 3010 tested combinations. This places it in the bottom 8% of all systems, which is a disastrous result for a system with a 90th percentile CPU. The data suggests that the GPU is dragging the entire system down to a level comparable to old, low-end hardware. This ranking is more aligned with the GPU's 5th percentile standing than the CPU's 90th percentile, which underscores the GPU's dominance as the performance limiter. The rank implies that most other CPU-GPU pairings tested, even those with much weaker CPUs, achieve better results in Roblox because they have more capable graphics hardware. The CPU's performance is effectively nullified by the GPU's inability to render frames quickly enough.

The data points to a severe system imbalance. While the CPU can handle complex game logic and physics, the GPU's low fill rate and memory bandwidth starve the display of frames. The combo's rank reflects the fact that a powerful CPU cannot compensate for a weak GPU in a graphics-intensive task. The fact that it is ranked 2774th means that 236 other combinations are slower in this game, but the vast majority (over 2700) deliver a better experience. This position reflects a pairing where the component with the lowest capability dictates the overall performance, and in this case, that component is severely underpowered for the task.

Settings Recommendations

The measured FPS data provides a clear guide for the best experience. At 1080p, the Low preset offers the highest average FPS at 154, which is ideal for high-refresh-rate monitors. However, the Medium preset at 140 FPS (with a min of 119) provides a better balance between visual quality and smoothness, ensuring the frame rate does not drop below 120 FPS. The High preset at 124 FPS is also a viable option, but the Ultra preset's 101 FPS average might be too low for competitive play. The data suggests that Medium at 1080p provides the best overall experience, as it offers high frame rates while improving visual fidelity over Low.

At 1440p, the situation is more nuanced. The Low preset averages 103 FPS, which is still smooth. The Medium preset, with an average of 94 FPS and a minimum of 80, is a strong choice for a more detailed image without sacrificing too much performance. The High preset at 83 FPS is acceptable, but the Ultra preset drops to 67 FPS, which may feel less responsive. For 1440p, the Medium preset is the recommended choice, as it stays well above 60 FPS and provides a noticeable visual upgrade over Low. For 4K gaming, the data shows that the system is not well-suited. The Low preset at 58 FPS is the only option that approaches a playable frame rate. The Medium preset at 53 FPS is borderline, but the High and Ultra presets, at 47 and 38 FPS respectively, are too slow for a smooth experience. Users should stick to Low or Medium at 4K if they must use this resolution, but the data implies that 1440p is the practical ceiling for this combo.

Resolution Scaling

The FPS scaling from 1080p to 4K is the most telling indicator of the system's bottleneck. On the High preset, the average FPS drops from 124 at 1080p to 83 at 1440p and then to 47 at 4K. This is a 33% drop from 1080p to 1440p, followed by a 43% drop from 1440p to 4K. The scaling is not linear, and the increasing percentage drop at higher resolutions is a classic sign of a GPU that is running out of memory bandwidth and pixel processing power. If the CPU were the bottleneck, the frame rate would remain relatively stable as resolution increases, since the CPU workload does not change significantly. Instead, the frame rate plummets, confirming that the Arc B370 is the limiting component.

This pattern is consistent across all settings. For instance, on Low, the average FPS drops from 154 at 1080p to 103 at 1440p (a 33% drop) and then to 58 at 4K (a 44% drop). The data suggests that the GPU's shared memory architecture is a major contributor to this issue. As the resolution increases, the amount of memory required for the framebuffer grows, and the GPU must contend with the CPU for access to system memory. This contention likely leads to severe bandwidth limitations, which are exacerbated at 4K. The performance degradation is so steep that it implies the GPU is not merely underpowered but also inefficient at handling high-resolution workloads, a consequence of its integrated design and lack of dedicated video memory. The system's performance is therefore heavily tied to the resolution, and the data makes it clear that this combo is only really comfortable at 1080p.
