Roblox

Roblox is not a typical stress test for flagship hardware, but the data for the Intel Core Ultra 9 290K Plus and NVIDIA GeForce RTX 4080 combination reveals a clear performance curve that depends heavily on resolution and settings. The measured frames per second show that this pairing is capable of high refresh rates at 1080p, but the demands of 4K with this specific game engine create a bottleneck that prevents the hardware from reaching its full potential. The following analysis breaks down the measured data to provide a practical guide for what to expect from this specific configuration.

Resolution Scaling

The performance drop from 1080p to 4K is significant and follows an expected pattern for a game like Roblox, which is often more sensitive to CPU and draw calls than raw GPU throughput. At 1080p with High settings, the combo produces an average of 101 FPS. When moving to 1440p, the average drops to 75 FPS, which is a 26 FPS reduction. Pushing further to 4K results in an average of 50 FPS, a 51 FPS drop from the 1080p baseline. This scaling indicates that the RTX 4080 is not the primary limiting factor at lower resolutions; instead, the game's engine and the CPU's ability to feed the GPU become the bottleneck.

The data shows a more pronounced scaling effect when looking at the Low preset. At 1080p Low, the system achieves 157 FPS. At 1440p Low, it drops to 138 FPS, and at 4K Low, it falls to 91 FPS. The 1440p to 4K transition at Low settings is particularly steep, showing a 47 FPS drop. This suggests that even with reduced graphical load, the sheer pixel count at 4K begins to saturate the GPU's capabilities. The fact that 4K Low (91 FPS) is faster than 1080p Ultra (96 FPS) but slower than 1080p High (101 FPS) highlights that the game's visual settings have a substantial impact on the frame rate, sometimes more than the resolution change itself.

The difference between 1080p and 1440p is relatively modest in percentage terms compared to the jump to 4K. For instance, at Medium settings, the average goes from 137 FPS at 1080p to 102 FPS at 1440p, a 25.5% decrease. However, the jump from 1440p Medium to 4K Medium is a 34.3% decrease, going from 102 FPS to 67 FPS. This indicates that 4K is where the RTX 4080's memory bandwidth and processing power become the decisive factor. The combination of the Core Ultra 9 290K Plus and RTX 4080 is powerful, but for those seeking 4K gameplay, the results show that settings must be managed carefully to maintain a smooth experience.

Settings Recommendations

The measured data provides a clear hierarchy for which preset offers the best balance between visual quality and frame rate. At 4K, the Ultra preset yields an average of 47 FPS, which is playable but not ideal for fast-paced action. The High preset is slightly better at 50 FPS, but the Medium preset provides a significant jump to 67 FPS. Given that the Medium preset shows a minimum of 57 FPS and a maximum of 77 FPS, it is the most viable option for 4K gaming on this hardware. The Low preset at 4K delivers 91 FPS, which is excellent for competitive play but sacrifices visual fidelity. For a 4K experience, Medium is the recommended choice to stay comfortably above the 60 FPS threshold.

At 1440p, the options become more flexible. The Ultra preset averages 71 FPS, which is smooth for most games. The High preset averages 75 FPS, and the Medium preset averages 102 FPS. The Low preset hits 138 FPS, which is ideal for high-refresh-rate monitors. The data suggests that at 1440p, users can comfortably select High or Ultra for a visually rich experience without dropping below 70 FPS. If a higher refresh rate is the priority, Medium provides a substantial boost in average FPS while still maintaining a minimum of 87 FPS.

At 1080p, the system has enough headroom to run any preset at high frame rates. The Ultra preset averages 96 FPS, while High averages 101 FPS, and Medium averages 137 FPS. The Low preset reaches 157 FPS. For 1080p gaming, the Ultra and High presets are nearly identical in performance, so the choice comes down to personal preference for visual effects. The Medium preset is the best choice for those who want to maximize frame rates on a 144Hz or 165Hz monitor, as it provides a significant jump in average FPS over High while remaining visually acceptable. The data shows that this hardware is never truly CPU-bound at 1080p, as even the most demanding preset stays above 90 FPS.

GPU Role

The NVIDIA GeForce RTX 4080 plays a critical role in this system, particularly as resolution increases. Its 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is essential for handling the high-resolution textures and assets that Roblox can present. The GPU's base clock is 2205 MHz with a boost clock of 2505 MHz, and these clocks allow it to maintain high utilization in graphically intensive scenes. The data indicates that the GPU is the primary driver of the frame rate differences between presets, as the CPU is less likely to be the bottleneck at higher resolutions.

The RTX 4080's architecture, Ada Lovelace, includes 76 ray tracing cores and 304 tensor cores, which are not directly utilized by Roblox's standard rendering but contribute to the overall feature set. The GPU's 48.74 TFLOPS of FP32 performance is more than sufficient for this game, and the data shows that even at 4K Ultra, the system manages an average of 47 FPS. This suggests that the game engine itself is the limiting factor rather than the raw compute power of the GPU. The measured scores for the GPU, such as a Passmark G3D score of 34457, place it in the 86th percentile of all GPUs, confirming its high-end status.

The comparison to its nearest rivals shows that the RTX 4080 is a well-balanced card. It is 0.1% behind the RTX 4080 SUPER in average benchmark score, which is a negligible difference. It also outperforms the AMD Radeon Pro W5700X by 1.1% and the AMD Radeon RX 6750 GRE 12 GB by 2.6%. These deltas are small, indicating that in this game, the specific GPU model matters less than the settings and resolution chosen. The GPU's 320W TDP and triple-slot design are typical for this performance class, and its 16 GB of VRAM is ample for Roblox at any setting.

How This Combo Ranks

The combination of the Intel Core Ultra 9 290K Plus and the NVIDIA GeForce RTX 4080 ranks 3381 out of 3711 tested combos for this game. This places it in the lower portion of the rankings, which is surprising given the high-end nature of both components. The percentile for the CPU is 96, meaning it performs better than 96% of all CPUs in general benchmarks, and the GPU is in the 86th percentile of all GPUs. However, the rank of 3381 out of 3711 indicates that this specific pairing is not optimal for Roblox, likely due to the game's engine being more dependent on single-thread performance and memory latency than on the massive multi-core capabilities of the CPU.

The CPU's benchmark scores are impressive, with a Cinebench R23 multi-core score of 51731 and a single-core score of 7303. It is 0.2% ahead of the Intel Core Ultra 9 285K and 1.1% ahead of the AMD EPYC 4584PX in average benchmark score. These rivals are all high-end desktop or server processors, but the data shows that the Core Ultra 9 290K Plus's 24 cores and 24 threads do not translate into a top-tier ranking for Roblox. The game likely does not scale well across all 24 cores, which is why the combo rank is lower than expected. The data suggests that a system with a faster single-core CPU and a similarly powerful GPU might rank higher for this specific game.

The combo rank of 3381 out of 3711 is a relative measure, and it does not mean the experience is poor. The measured FPS shows that the system is capable of smooth gameplay at 1080p and 1440p, with 4K requiring settings adjustments. The rank is more indicative of how other, often less expensive, combinations might perform better in this particular game. For a general-purpose high-end system, this CPU and GPU pairing is excellent, but for Roblox specifically, the data shows that the hardware is not fully utilized.
