Roblox

Roblox, a long-running sandbox title from 2006, presents an interesting case for modern hardware. This analysis examines the Intel Core Ultra 5 225 paired with the NVIDIA GeForce RTX 4070 SUPER, using measured frame rate data across three resolutions and four quality presets. The data shows a combination that is overwhelmingly GPU-limited at lower settings but reveals a more balanced profile as resolution and visual fidelity increase.

Resolution Scaling

The frame rate progression from 1080p to 4K demonstrates classic scaling behavior, but with a twist specific to Roblox's engine. At 1080p with Low settings, the combo produces 560 FPS. Moving to 1440p Low drops that to 374 FPS, a 33% reduction. At 4K Low, the average falls to 211 FPS, which is a 62% drop from the 1080p figure. This steep decline indicates that even at Low settings, the GPU is becoming the primary bottleneck as pixel count increases.

The High preset tells a similar story. The 1080p result of 450 FPS falls to 300 FPS at 1440p (a 33% decrease) and then to 170 FPS at 4K (a 62% decrease from 1080p). The consistency of these percentage drops across Low and High presets suggests that the scaling penalty is dominated by resolution rather than settings complexity. The RTX 4070 SUPER's 504.2 GB/s of memory bandwidth and 12 GB of GDDR6X VRAM are sufficient to feed the render pipeline, but the raw compute demand of 4K output still exacts a heavy toll.

The Medium preset, which is the only one with complete min and max FPS data, illustrates the performance envelope. At 1080p Medium, the average is 509 FPS with a minimum of 433 and maximum of 586. At 1440p Medium, the average drops to 340 FPS with a range of 289 to 391. At 4K Medium, the average settles at 192 FPS with a range of 163 to 221. The spread between min and max FPS widens slightly at lower resolutions, indicating that CPU-driven frame time variance becomes more noticeable when the GPU is less stressed.

The Ultra preset shows the most severe scaling. From 365 FPS at 1080p, it drops to 244 FPS at 1440p (a 33% reduction) and then to 138 FPS at 4K (a 62% reduction from 1080p). This pattern strongly suggests that the limiting component shifts from the CPU at low resolutions to the GPU at 4K, but the CPU still plays a critical role in maintaining high average frame rates even at the highest settings.

CPU Role

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. It operates with a base clock of 3.30 GHz and a boost clock of 4.90 GHz, with 20 MB of shared L3 cache. In Cinebench R23, it scores 25891 in multi-core and 3655 in single-core tests. These numbers place it in the 85th percentile of all CPUs, with an average benchmark score of 36938.

The nearest rivals provide context for its performance tier. The AMD Ryzen 5 5600F scores 36945, a delta of 0% from the Intel part. The AMD Ryzen 5 5500X3D scores 37018, which is 0.2% higher. The AMD Ryzen AI 7 PRO 450 and Intel Core i9-12900T score 37093 and 37112, respectively, representing deltas of 0.4% and 0.5% higher. This tight cluster indicates that the Core Ultra 5 225 sits squarely in the mid-range desktop performance envelope, trading blows with older and newer AMD designs.

In Roblox, the CPU's influence is most apparent at 1080p where frame rates exceed 500 FPS. The single-core performance, evidenced by the 3655 Cinebench R23 score, is sufficient to drive high draw call throughput. The 10 cores and 10 threads handle Roblox's physics and scripting workloads, which are typically not heavily multi-threaded. The lack of hyper-threading (10 cores, 10 threads) does not appear to hinder performance, as the game rarely utilizes more than a few threads.

The PassMark single-thread score of 4412 and multi-thread score of 30459 reinforce that this CPU provides a balanced profile. For Roblox, the boost clock of 4.90 GHz is likely the more critical specification, as the game's primary CPU load consists of single-threaded game logic and rendering command submission. The 65 W TDP suggests efficient operation, though the benchmark data does not include power draw figures.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is built on the Ada Lovelace architecture with the AD104 chip, manufactured on a 5 nm process. It features 7168 shading units, 224 texture mapping units, and 80 render output units, with 56 RT cores and 224 tensor cores. The boost clock reaches 2475 MHz, and the memory runs at 1313 MHz with 21 Gbps effective speed. The 12 GB of GDDR6X memory is connected via a 192-bit bus, providing 504.2 GB/s of bandwidth.

In synthetic benchmarks, the GPU achieves a PassMark G3D score of 29995 and a Geekbench Vulkan score of 205624. Its average benchmark score is 43223, placing it in the 83rd percentile of all GPUs. The nearest rivals are interesting: the NVIDIA Quadro M6000 24 GB scores 43262 (0.1% higher), the NVIDIA GeForce RTX 5050 Mobile scores 43268 (0.1% higher), the NVIDIA Quadro M6000 scores 43301 (0.2% higher), and the NVIDIA GeForce RTX 4090 Mobile scores 43667 (1% higher). This indicates that the desktop RTX 4070 SUPER performs comparably to a mobile flagship, despite the laptop part's higher transistor count.

For Roblox, the GPU's role becomes dominant at 4K resolution. The 211 FPS at 4K Low versus 138 FPS at 4K Ultra shows a 35% performance penalty for enabling the Ultra preset. The 12 GB VRAM is ample for Roblox, which is not a VRAM-intensive title, so the limiting factor is raw pixel throughput. The fp32 performance of 35.48 TFLOPS is more than sufficient for the game's relatively simple shaders, but the sheer number of pixels at 3840x2160 still overwhelms the render pipeline at higher quality settings.

The 80 ROPs and 554.4 GTexel/s texture rate suggest that the GPU can handle complex scenes efficiently, but Roblox's blocky aesthetic does not heavily utilize texture filtering. The data shows that at 1080p, the GPU is rarely the bottleneck—the 560 FPS at Low settings indicates headroom remains. At 4K, however, the GPU is clearly the limiting component, as evidenced by the 211 FPS ceiling at Low settings.

Measured FPS Breakdown

The complete dataset reveals consistent scaling across all settings. At 1920x1080, the Low preset achieves 560 FPS, Medium 509 FPS, High 450 FPS, and Ultra 365 FPS. The step from Low to Ultra represents a 35% reduction in average FPS. The Medium preset's minimum of 433 FPS and maximum of 586 FPS show a tight frame time distribution, suggesting stable performance.

At 2560x1440, the averages are 374 FPS (Low), 340 FPS (Medium), 300 FPS (High), and 244 FPS (Ultra). The Medium preset reports a minimum of 289 FPS and maximum of 391 FPS. The drop from Low to Ultra is 35%, identical to the 1080p scaling. This consistency implies that the quality presets have a multiplicative effect on render cost, independent of resolution.

At 3840x2160, the averages fall to 211 FPS (Low), 192 FPS (Medium), 170 FPS (High), and 138 FPS (Ultra). The Medium preset's minimum is 163 FPS and maximum is 221 FPS. The 35% penalty from Low to Ultra persists, but the absolute numbers are now in a range where high refresh rate monitors may not be fully utilized. The 4K Ultra result of 138 FPS is still playable, but it is 75% lower than the 1080p Low result.

The data shows that the Medium preset offers the most balanced experience across all resolutions. At 1440p Medium, the 340 FPS average with a 289 FPS minimum ensures smooth gameplay even in busy scenes. At 4K Medium, the 192 FPS average and 163 FPS minimum remain above the 144 Hz threshold, making it the recommended preset for 4K displays. The Ultra preset at 4K, while visually superior, dips to 138 FPS on average, which may cause judder on high refresh rate panels.

Settings Recommendations

Based on the measured data, the Medium preset offers the best balance of visual quality and performance across all three resolutions. At 1080p Medium, the 509 FPS average and 433 FPS minimum ensure smooth gameplay with headroom for future content updates. At 1440p Medium, the 340 FPS average and 289 FPS minimum comfortably exceed the refresh rate of most high-end monitors.

For 4K displays, the Medium preset is the clear recommendation. The 192 FPS average and 163 FPS minimum provide a significant buffer above the 144 Hz threshold, ensuring consistent frame delivery even during complex scenes. The High preset at 4K (170 FPS average) is also viable, but the 22 FPS difference between Medium and High at 4K is more pronounced than at lower resolutions.

The Ultra preset is only recommended for 1080p and 1440p users. At 1080p Ultra, the 365 FPS average still leaves ample headroom. At 1440p Ultra, the 244 FPS average is sufficient for 240 Hz displays. However, at 4K Ultra, the 138 FPS average is borderline for high refresh rate gaming, and the lack of min/max data for this setting introduces uncertainty about frame time consistency.

For competitive play, the Low preset at 1080p (560 FPS) or 1440p (374 FPS) maximizes frame rates and minimizes input latency. The 62% drop from 1080p Low to 4K Low highlights that even minimal settings cannot fully compensate for the pixel count increase at 4K. The data suggests that users with 4K displays should prioritize Medium settings to balance visual fidelity with the high frame rates that Roblox's fast-paced gameplay benefits from.
