Roblox

Roblox presents an unusual scaling profile for the Intel Core Ultra 5 245 and AMD Radeon RX 570 combination. The data suggests a system where the GPU is the primary constraint, but not uniformly so across all settings. The measured frames per second (FPS) drop significantly as resolution increases, but the magnitude of that drop is heavily modulated by the graphics preset, revealing a complex interplay between the CPU's strong single-threaded performance and the GPU's aging architecture.

Resolution Scaling

The FPS degradation from 1920x1080 to 3840x2160 is steep and consistent, but the slope changes with the quality preset. At Low settings, the average FPS falls from 148 at 1080p to 99 at 1440p, a 33% reduction, and then to 56 at 4K, another 43% drop. This steep decline indicates that even at Low settings, the rendering load at 4K is overwhelming the AMD Radeon RX 570's capabilities. The 4K Low result of 56 FPS is only 38% of the 1080p Low score, showing that raw pixel count is a dominant factor.

For Medium settings, the pattern is similar but with a slightly gentler slope between 1440p and 4K. The average drops from 135 FPS at 1080p to 90 FPS at 1440p (a 33% reduction), and then to 51 FPS at 4K (a 43% reduction from 1440p). The High preset shows the most linear scaling, with 119 FPS at 1080p, 79 FPS at 1440p, and 45 FPS at 4K. This represents a 62% reduction from 1080p to 4K, which is a massive performance hit.

The Ultra preset exhibits the most dramatic collapse. It starts at 97 FPS at 1080p, which is already lower than Low at 4K. It drops to 64 FPS at 1440p and then plummets to 36 FPS at 4K. The fact that 1080p Ultra (97 FPS) is significantly higher than 4K Low (56 FPS) highlights that resolution is the single largest performance factor, outweighing even the massive difference between the Low and Ultra presets. This data strongly implies that the RX 570 is the limiting component; the Intel Core Ultra 5 245's 14 cores are not the bottleneck, as even the most demanding CPU scenarios at 1080p yield playable frame rates.

FAQ

GPU Role

The AMD Radeon RX 570 is clearly the performance limiter in this configuration. Its specifications, while respectable for its generation, are dated. The GPU has 4 GB of GDDR5 memory on a 256-bit bus, yielding a bandwidth of 224.0 GB/s. Its base clock is 1168 MHz with a boost clock of 1244 MHz. The 2048 shading units and 32 ROPs are the hardware that must process the pixel data, and the measured FPS indicates they are saturated at higher resolutions.

The GPU's benchmark scores corroborate its mid-range positioning. Its average benchmark score is 28766, placing it in the 74th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 470, is only 0.8% behind, while the AMD Radeon RX 6800M is 0.4% ahead. This shows the RX 570 is a solid performer relative to its direct peers, but those peers are all older or mobile parts. In Roblox, the GPU's 4 GB VRAM is not the primary issue at these settings; instead, the raw compute power determines the frame rate. The 5.095 TFLOPS FP32 performance is sufficient for 1080p but struggles to maintain 60 FPS at 4K High, where it only averages 45 FPS.

The GPU's power draw is listed at 150 W TDP, which is modest, but its performance envelope is clearly defined. The data shows that to achieve 60 FPS, the GPU must be paired with either a 1080p resolution or the Low preset at 1440p. At 4K, it is simply out of its depth, regardless of the settings. This suggests that for Roblox, the RX 570 is a capable 1080p card that can also handle 1440p with reduced settings, but it is not a 4K solution.

Measured FPS Breakdown

The measured FPS data provides a clear matrix of performance across resolutions and settings. At 1920x1080, the system performs admirably. The Low preset achieves an average of 148 FPS, which is excellent for competitive play. Medium settings produce 135 FPS, with a minimum of 114 FPS and a maximum of 155 FPS, showing good consistency. High settings yield 119 FPS, and even the demanding Ultra preset maintains an average of 97 FPS. All 1080p presets are above 90 FPS, indicating a smooth experience.

At 2560x1440, the performance drops noticeably. The Low preset averages 99 FPS, which is still playable. Medium settings average 90 FPS, with a minimum of 76 FPS and a maximum of 103 FPS. High settings drop to 79 FPS, and Ultra falls to 64 FPS. These numbers suggest that 1440p is playable, but the Ultra preset is borderline for a 60 FPS target, and the High preset is the sweet spot for a consistent 60+ FPS experience.

At 3840x2160, the performance is severely constrained. The Low preset averages 56 FPS, which is the only 4K setting above 50 FPS. Medium settings average 51 FPS, with a minimum of 43 FPS and a maximum of 58 FPS, indicating potential frame hitches. High settings drop to 45 FPS, and Ultra falls to 36 FPS. None of the 4K presets can consistently maintain 60 FPS, making 4K gaming impractical with this GPU in Roblox.

The transition from 1080p to 1440p results in an average FPS loss of approximately 33-35% across presets. The transition from 1440p to 4K results in a further loss of 43-44% across most presets, showing that the performance scaling is non-linear and the GPU's fill rate is being exhausted.

How This Combo Ranks

This specific combination of an Intel Core Ultra 5 245 and AMD Radeon RX 570 ranks 2885 out of 3010 tested combos in Roblox. This places it in the bottom 4% of all tested systems, which is a surprising result given the individual components' benchmark scores. The CPU's percentile vs all CPUs is 90, meaning it is better than 90% of all CPUs. The GPU's percentile vs all GPUs is 74, meaning it is better than 74% of all GPUs.

The low combo rank suggests that while each part is individually decent, their pairing is not optimal for this specific game. The CPU is a high-end part, but Roblox is likely not heavily multi-threaded, leaving the 14 cores mostly idle. The GPU is a mid-range part, and its performance is the limiting factor. The rank indicates that there are many other combinations of hardware that achieve better results in Roblox, likely due to having more powerful GPUs.

The data implies that pairing a high-end CPU like the Core Ultra 5 245 with an older, entry-level GPU like the RX 570 creates a bottleneck that prevents the system from ranking well. The CPU's power is wasted because the GPU cannot render frames fast enough to utilize it. This result is a cautionary tale about balanced system building, even if the individual components have high benchmark scores. The rank is a stark contrast to the CPU's 90th percentile standing, highlighting that a strong processor cannot compensate for a weak graphics card in a GPU-bound scenario.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture. It has a base clock of 3.50 GHz and a boost clock of 5.10 GHz. Its 24 MB of shared L3 cache and 3 MB of L2 cache per core provide ample data storage for game logic. The CPU's benchmark scores are strong, with a Cinebench R23 multi-core score of 32924 and a single-core score of 4648. Its average benchmark score is 48995, placing it in the 90th percentile of all CPUs.

In Roblox, the CPU's role appears to be secondary to the GPU. The data shows that at 1080p Low, the system achieves 148 FPS. This suggests the CPU is capable of handling the game's simulation and physics without being a bottleneck. However, the game is likely not utilizing all 14 cores effectively. The Passmark multi-thread score of 38706 and the single-thread score of 4394 indicate that the CPU has both high multi-core and single-core throughput. The single-thread performance is crucial for Roblox, which often relies on a few main threads for game logic.

The fact that the FPS drops so dramatically at higher resolutions confirms that the CPU is not the limiting factor. If it were, the FPS would remain relatively stable across resolutions. Instead, the FPS drops in proportion to the pixel count, which is a classic sign of a GPU bottleneck. The CPU's performance is sufficient to feed the GPU at 1080p, but the GPU cannot render the increased load at 4K. This CPU is vastly overqualified for this pairing in Roblox, and its capabilities are underutilized due to the GPU's limitations.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's display resolution and performance goals. For 1080p, the High preset offers an excellent balance, averaging 119 FPS. This provides a significant visual upgrade over Low (148 FPS) while still maintaining a high frame rate. The Ultra preset at 97 FPS is also viable if the user prefers maximum visual fidelity, but the 18% FPS cost may not be worth it for a game like Roblox.

For 1440p, the Medium preset is the best recommendation. It averages 90 FPS, which is smooth, and its minimum of 76 FPS ensures it stays above the 60 FPS threshold. The High preset at 79 FPS is also acceptable, but it comes closer to the 60 FPS line. The Low preset at 99 FPS offers the highest frame rate but sacrifices visual quality. The Ultra preset at 64 FPS is not recommended as it risks dropping below 60 FPS during busy scenes.

For 4K, the data suggests that the system is not adequately equipped for a consistently smooth experience. The Low preset at 56 FPS is the only option that approaches playability, but it may still experience stutters. The Medium preset at 51 FPS with a minimum of 43 FPS is risky. Users with a 4K display should consider lowering the resolution to 1440p or 1080p for a better experience. The Ultra preset at 36 FPS is not recommended for any gameplay scenario.

The best overall experience per the measured rows is 1080p High, offering a high frame rate with good visual quality. For users prioritizing maximum FPS, 1080p Low is the clear winner. The data shows that the Medium preset provides the most consistent frame pacing, as it is the only preset with recorded minimum FPS values that are not significantly lower than the average, indicating a stable performance profile.
