# How This Combo Ranks

The Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 4080 lands at rank 1223 out of 3711 tested combos for Roblox, placing it in the top third of all configurations measured. This rank reflects a system that delivers well above playable framerates at every resolution tested, though it is not the absolute top-tier combination for this title.

The RTX 4080 sits at the 86th percentile among all GPUs, which is strong but not elite, while the Core Ultra 7 155H holds the 83rd percentile among all CPUs. In Roblox, where the rendering load is relatively modest compared to AAA titles, this pairing proves more than sufficient. The data shows the combo outpacing the vast majority of alternatives, with 2488 tested configurations ranking below it.

Looking at direct rivals, the CPU's nearest competitor in synthetic benchmarks is the Intel Core i5-14600T, which scores virtually identically with a delta of 0%. The AMD Ryzen AI 7 PRO 360 trails by just 0.1%, while the AMD Ryzen 5 7400F and AMD Ryzen 7 PRO 6850H are 0.2% and 0.4% ahead respectively. These differences are negligible in practice, meaning the CPU is not the differentiating factor in Roblox performance.

On the GPU side, the RTX 4080's closest rival is the RTX 4080 SUPER, which scores 0.1% higher on average. The AMD Radeon Pro W5700X is 1.1% ahead, while the AMD Radeon RX 6750 GRE 12 GB and AMD Radeon 8060S are 2.6% and 2.7% ahead respectively in aggregate benchmarks. Again, these margins are small enough that real-world Roblox performance will be governed more by the game's engine and CPU behavior than by these synthetic differences.

Given the measured framerates, this combo is clearly overqualified for Roblox at standard display refresh rates. Even at 4K Ultra settings, the system maintains 114 FPS average, which exceeds the refresh rate of most monitors. The rank of 1223 out of 3711 suggests that while many weaker combos can also run Roblox smoothly, this particular pairing offers headroom for demanding user-created experiences within the game.

Settings Recommendations

The measured data reveals a clear pattern: Roblox is not demanding enough to stress this hardware at any preset below 4K. At 1080p, even the most punishing Ultra preset produces 301 FPS average, which exceeds the maximum refresh rate of virtually all gaming monitors. The Medium preset at 1080p delivers 420 FPS average with a minimum of 357 FPS, offering a substantial buffer against frame drops during complex scenes.

For 1440p users, the Ultra preset still achieves 201 FPS average, which is more than sufficient for 144Hz or even 165Hz displays. The High preset at 248 FPS and Medium at 280 FPS provide additional headroom, but the visual fidelity gains from Ultra are worth the modest performance cost. The data suggests that 1440p Ultra is the sweet spot for this combination, balancing visual quality with framerates that exceed any display's refresh capabilities.

At 4K, the choice becomes more nuanced. Ultra settings drop to 114 FPS average, which is still playable on 120Hz displays but leaves less margin for demanding user-generated content. High settings at 140 FPS provide a better balance, while Medium at 158 FPS with a minimum of 135 FPS offers the safest experience. Low settings at 174 FPS are unnecessary unless chasing maximum frame times.

The recommendation is to run Roblox at 1440p Ultra for the best visual experience, as the 201 FPS average leaves ample headroom. For 4K users, High settings at 140 FPS is the optimal compromise, as the jump to Ultra costs 26 FPS for what is likely a marginal visual difference in Roblox's art style. The Medium preset at 4K (158 FPS) is the conservative choice for those prioritizing frame rate stability above all else.

Measured FPS Breakdown

At 1920x1080, the system demonstrates extraordinary performance across all presets. Low settings produce 461 FPS average, while Medium achieves 420 FPS with a minimum of 357 FPS and a maximum of 483 FPS. High settings drop to 371 FPS, and Ultra still maintains 301 FPS. The progression from Low to Ultra shows a 160 FPS difference, but even the lowest figure is far beyond any display's capability.

Moving to 2560x1440, the results remain impressive. Low settings yield 308 FPS, Medium delivers 280 FPS with a 238-322 FPS range, High produces 248 FPS, and Ultra maintains 201 FPS. The scaling from 1080p to 1440p shows roughly a 33% reduction in framerate across most presets, which aligns with the increased pixel count. The minimum FPS of 238 at Medium settings indicates that even worst-case scenarios remain well above 144Hz.

At 3840x2160, performance becomes more moderate but still exceptional. Low settings achieve 174 FPS, Medium delivers 158 FPS with a 135-182 FPS range, High produces 140 FPS, and Ultra drops to 114 FPS. The 4K results show a more pronounced drop from 1440p, with framerates roughly halving. The Ultra preset at 114 FPS is the only configuration that approaches the threshold where some high-refresh displays might not be fully saturated.

The measured data shows no anomalies or unexpected bottlenecks. Each resolution and settings combination follows a logical progression, with Medium consistently offering the best balance of performance and quality. The minimum FPS values recorded only for Medium presets suggest that the game's frame pacing is stable, with the 4K Medium minimum of 135 FPS still comfortably above standard 120Hz refresh rates.

Resolution Scaling

The framerate scaling from 1080p to 4K reveals important insights about the system's bottleneck. At Low settings, the transition from 1920x1080 (461 FPS) to 2560x1440 (308 FPS) represents a 33.2% reduction, while moving from 1440p to 3840x2160 (174 FPS) cuts another 43.5%. This progressive decline indicates that the GPU is increasingly the limiting factor as resolution rises.

For Ultra settings, the scaling is similar: 301 FPS at 1080p drops to 201 FPS at 1440p (33.2% reduction), then to 114 FPS at 4K (43.3% reduction). The consistency of these percentages across different presets suggests that the bottleneck shifts uniformly with pixel count. At 1080p, the CPU likely plays a more significant role, as the framerates are high enough that per-frame CPU work can introduce limits.

The RTX 4080's memory bandwidth of 716.8 GB/s and 16 GB of GDDR6X memory are more than adequate for Roblox at any resolution. The GPU's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s provide substantial headroom. The 48.74 TFLOPS of FP32 performance is far beyond what Roblox requires, confirming that the game is not GPU-compute bound.

The Core Ultra 7 155H's 89.6 GB/s memory bandwidth and dual-channel configuration are sufficient for the game's data requirements. The CPU's 24 MB of shared L3 cache and 2 MB per-core L2 cache help maintain consistent frame delivery. At 1080p, where framerates exceed 300 FPS, the CPU's per-core performance becomes more relevant, but the measured results show no signs of CPU limitation even at these extreme framerates.

CPU Role

The Intel Core Ultra 7 155H features 16 cores and 22 threads, combining performance and efficiency cores in a Meteor Lake architecture. The base clock of 3.80 GHz boosts to 4.80 GHz, providing strong single-thread performance when needed. The CPU's 7 nm process node and 28 W TDP indicate a mobile-focused design that balances power efficiency with capability.

Synthetic benchmarks show the CPU's strengths: Cinebench R23 multi-core score of 15028 and single-core score of 1743, with Cinebench R20 scores of 8754 and 1235 respectively. PassMark results include a multi-thread score of 24873 and single-thread score of 3468, with floating point math at 63703 and integer math at 86870. These figures place the CPU at the 83rd percentile, with its average benchmark score of 32697 nearly identical to its closest rival.

In Roblox, the CPU's role is less critical than in CPU-intensive simulations, but the data still shows its influence. The game's physics and scripting workloads can benefit from multi-core performance, and the 22 threads provide ample parallelism. The CPU's 24 MB shared L3 cache helps reduce memory latency, which is beneficial for the game's asset streaming and world interactions.

The measured framerates suggest that the CPU is not a limiting factor at any resolution for this combo. Even at 1080p Low settings with 461 FPS average, the system maintains consistent performance. The CPU's 83rd percentile ranking indicates it is more capable than the majority of processors, and its 16-core configuration ensures it can handle Roblox's background tasks while maintaining high framerates.

The Core Ultra 7 155H's nearest rivals in synthetic benchmarks are all desktop or high-end mobile chips with similar aggregate scores. The 0% delta with the Intel Core i5-14600T and 0.1% delta with the AMD Ryzen AI 7 PRO 360 demonstrate that the CPU is competitive with alternatives in its class. For Roblox specifically, the CPU's generous core count and high boost clock provide more than enough processing power, making the GPU the primary determinant of framerate at higher resolutions.
