Roblox

Roblox is not the typical stress test for a high-end desktop pairing, but the measured data for the Intel Core Ultra 5 245 and NVIDIA GeForce RTX 4080 SUPER reveals a system that is dramatically overqualified for the task, delivering triple-digit frame rates even at 4K Ultra settings. The performance envelope here is defined by the game's relatively modest engine demands and the sheer headroom of both components, resulting in a combination that prioritizes maximum smoothness and visual fidelity over the need for aggressive optimization.

Resolution Scaling

The frame rate scaling from 1080p to 4K shows a classic pattern of GPU load increasing, though the absolute numbers remain exceptionally high. At 1920x1080 with High settings, the average FPS is 515. Moving to 2560x1440 drops that to 343 FPS, a 33% reduction. The jump to 3840x2160 brings the average down to 194 FPS, which is another 43% reduction from the 1440p figure. This steep drop-off indicates that while the CPU is capable of feeding the GPU at lower resolutions, the GPU is finally being tasked with a significant workload as pixel count quadruples from 1080p to 4K.

The delta between Low and Ultra settings widens with resolution, which is typical. At 1080p, the difference between Low (640 FPS) and Ultra (417 FPS) is 223 FPS. At 1440p, that spread is 148 FPS (427 vs 279). At 4K, the gap compresses to 83 FPS (241 vs 158). This compression at higher resolutions strongly suggests that the RTX 4080 SUPER is the primary limiter at 4K Ultra, whereas at 1080p, the frame rate is likely being bounded by the game engine's single-threaded draw call processing or the CPU's capability, even with a 14-core processor. The data shows that the Core Ultra 5 245 has enough headroom to push past 600 FPS at 1080p Low, a figure that is purely academic for most displays.

The scaling pattern also highlights a point of diminishing returns. While 4K performance is excellent, the step from 1440p to 4K costs roughly 40-45% of the frame rate across all settings. For players using high-refresh-rate 1440p monitors, the 343 FPS average at High settings is far beyond what any display can show, making 4K a more sensible target for this hardware if visual clarity is the goal. The 4K Medium result of 220 FPS with a minimum of 187 FPS shows that even in the heaviest standard preset, the system maintains a frametime consistency that exceeds the refresh rate of all but the most exotic 240Hz 4K panels.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this pairing, and its specifications explain the robust 4K performance. It features 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 736.3 GB/s. For Roblox, which is not known for massive texture sets, this memory capacity and bandwidth are immense, effectively eliminating any possibility of a VRAM bottleneck. The GPU also boasts a boost clock of 2550 MHz and a base clock of 2295 MHz, running on the Ada Lovelace architecture with 10240 shading units.

The GPU's benchmark standing reinforces its position. It holds an 86th percentile ranking among all GPUs, with an average benchmark score of 54209. Its nearest rival, the NVIDIA GeForce RTX 4080, scores nearly identically at 54247, a negligible 0.1% difference. This puts the 4080 SUPER in a class of its own for this game, far ahead of the other listed competitors like the AMD Radeon RX 6750 GRE 12 GB, which trails by 2.7%. The data indicates that the GPU is never the primary constraint until 4K Ultra, and even then, the 158 FPS average is not a sign of weakness but rather proof of the game's scalability.

The measured 3DMark Steel Nomad DX12 score of 6600 and a Passmark G3D score of 34245 further confirm the GPU's high-end placement. The GPU's compute performance, evidenced by a Passmark GPU Compute score of 19822, is more than sufficient for any physics or logic offload Roblox might attempt. In practical terms, the RTX 4080 SUPER's role in this combo is to make every resolution and settings combination a non-issue. The only scenario where it is pushed is 4K Ultra, where it still delivers 158 FPS, a figure that is 10% lower than the 4K High result, showing the expected cost of the highest preset.

CPU Role

The Intel Core Ultra 5 245 provides the foundational performance for this combo, and its specs show it is well-matched to avoid bottlenecking the GPU. It has 14 cores and 14 threads, a configuration that relies on raw core count rather than hyper-threading. Its base clock is 3.50 GHz, with a boost clock of 5.10 GHz, which is crucial for Roblox's often single-threaded workload. The CPU's 24 MB of shared L3 cache and 3 MB per-core L2 cache provide fast data access, and its memory bandwidth is rated at 102.4 GB/s with DDR5 support.

In synthetic benchmarks, the CPU demonstrates strong single-core performance, which is the most critical metric for this game. Its Cinebench R23 single-core score of 4648 and Passmark Single Thread score of 4394 are excellent figures. The multi-core results are also solid, with a Cinebench R23 multi-core score of 32924 and a Passmark Multithread score of 38706. These scores place the CPU in the 90th percentile among all CPUs, with an average benchmark score of 48995. Its nearest rival, the AMD Ryzen 7 PRO 5755G, scores 49196, a mere 0.4% difference, showing that the Core Ultra 5 245 is competitive with top-tier mainstream processors.

The CPU's role in this combo is to ensure that the GPU is always fed with data. The data suggests it succeeds. At 1080p Low, the 640 FPS average is likely near the engine's logical limit, and the CPU's 5.10 GHz boost clock helps achieve that. The performance does not degrade artificially as settings increase, which implies the CPU is not the bottleneck. Even at 4K Ultra, where the GPU is working hardest, the CPU's latency and throughput are sufficient to keep the 158 FPS average stable. The CPU's 65W TDP and 3nm process node (TSMC) indicate an efficient design that doesn't generate excessive heat, allowing the boost clocks to persist under load.

How This Combo Ranks

The combination of the Core Ultra 5 245 and RTX 4080 SUPER ranks 231st out of 3010 tested combos in Roblox, placing it in the top 7.7% of all configurations. This rank is a function of both components' high percentiles but is somewhat surprising given the raw power available. The fact that it is not higher is likely due to the game's engine limits, where many high-end CPUs and GPUs produce similar, capped frame rates.

This ranking suggests that while the combo is exceptionally fast, there are other pairings that might achieve marginally higher frame rates at 1080p, likely due to CPUs with even higher single-core boosts or better memory latency. However, the rank of 231 is still a strong indicator of top-tier performance. The GPU's slight edge over its non-SUPER counterpart (0.1%) and the CPU's competitive standing against the Ryzen 9 7900 (0.5% difference) mean that this specific pairing is well-balanced. The data shows that for a game like Roblox, the rank is more about avoiding a weak link than having the absolute fastest components, and this combo has no weak links.

The deltaPct values for the CPU's rivals are all within 0.8%, meaning the Core Ultra 5 245 is essentially tied with the Intel Core i5-14600K and AMD Ryzen 9 7900. This wide parity in CPU performance means the GPU choice becomes the differentiator, and the RTX 4080 SUPER's 86th percentile ranking justifies the combo's high placement. The 3010 combos tested include many with lower-tier GPUs that would bottleneck at higher resolutions, so this combo's 4K performance, which is in the top percentile, is what drives its solid rank.

Measured FPS Breakdown

The measured data provides a complete picture of performance across three resolutions and four settings presets.

At 1920x1080, the results are exceptionally high:

• Low: 640 FPS average
• Medium: 582 FPS average, with a minimum of 495 FPS and maximum of 669 FPS
• High: 515 FPS average
• Ultra: 417 FPS average

At 2560x1440, the frame rates remain above 270 FPS:

• Low: 427 FPS average
• Medium: 388 FPS average, with a minimum of 330 FPS and maximum of 447 FPS
• High: 343 FPS average
• Ultra: 279 FPS average

At 3840x2160, the system still delivers over 150 FPS:

• Low: 241 FPS average
• Medium: 220 FPS average, with a minimum of 187 FPS and maximum of 253 FPS
• High: 194 FPS average
• Ultra: 158 FPS average

The Medium preset is the only one with recorded minimum and maximum FPS values, which allows for a precise analysis of frametime consistency. At 1080p Medium, the minimum of 495 FPS is 85% of the average, showing excellent stability. At 1440p Medium, the minimum of 330 FPS is 85% of the average, again showing that the system maintains a high floor. At 4K Medium, the minimum of 187 FPS is 85% of the average, indicating that even at the highest resolution, the frame pacing is consistent without major hitches.

Settings Recommendations

Based on the measured rows, the ideal settings depend on the target resolution and display refresh rate, but the data strongly suggests that Ultra settings are the best experience for this hardware.

At 4K, the Ultra preset produces 158 FPS. While this is lower than the 194 FPS at High, it is still far above the 144Hz refresh rate that is common on high-end 4K monitors. The visual fidelity jump from High to Ultra is likely worth the 36 FPS cost, as the system has ample headroom above 60 FPS. If a player has a 120Hz 4K display, Ultra is the only choice that fully utilizes the hardware. The Medium preset at 4K, with its 220 FPS average and 187 FPS minimum, is a fallback for those seeking absolute maximum framerates, but it sacrifices visual quality for numbers that exceed most display capabilities.

At 1440p, the Ultra preset's 279 FPS is the recommended choice. It clears the 240Hz threshold, which is the highest common refresh rate for 1440p monitors. The High preset's 343 FPS offers no practical benefit unless the display is a 360Hz model, which is rare. The data shows that the GPU has enough power to run Ultra without any concern, and the minimum FPS on Medium (330) suggests that Ultra would still have a high floor.

At 1080p, the Ultra preset's 417 FPS is the most sensible option. Even with a 360Hz esports monitor, this exceeds the display's capability. The Low preset's 640 FPS is purely for competitive scenarios where every millisecond counts, but for the vast majority of players, the visual improvements of Ultra are free in terms of playable smoothness. The CPU and GPU are both powerful enough that there is no reason to dial down settings at this resolution.

In summary, the best experience is to enable Ultra settings at any resolution, as the hardware provides enough performance to make the highest preset playable with a comfortable margin. The only exception would be a player with a 360Hz 1080p display who absolutely needs the highest possible frame rate, but the difference between 417 and 640 FPS is imperceptible in a game like Roblox. The measured data confirms that this combo is built for maximum visual quality without compromising on fluidity.
