Roblox

The AMD Ryzen 5 7400F paired with the NVIDIA GeForce RTX 4090 produces an exceptionally high-performance configuration for Roblox, with measured frame rates that far exceed the requirements of standard display refresh rates. This analysis breaks down the measured FPS data across three resolutions and four settings presets, examining the role of each component and how this specific combination ranks against other tested systems in the database.

Resolution Scaling

The measured FPS data reveals how the system's performance scales as resolution increases from 1920x1080 to 3840x2160. At the Low settings preset, the average frame rate drops from 711 FPS at 1080p to 474 FPS at 1440p, and finally to 268 FPS at 4K. This represents a significant scaling pattern: moving from 1080p to 1440p reduces performance by approximately 33%, while the jump from 1440p to 4K reduces it by an additional 43%. The overall drop from 1080p to 4K at Low settings is roughly 62%, indicating that the GPU is becoming increasingly burdened as pixel count rises.

At the Ultra settings preset, the scaling is similar but with lower absolute values. The system delivers 464 FPS at 1080p, 310 FPS at 1440p, and 175 FPS at 4K. The percentage drops are comparable to the Low preset, with a 33% reduction from 1080p to 1440p and a 44% reduction from 1440p to 4K. This consistency across settings suggests that the scaling penalty is primarily resolution-driven rather than settings-driven. The fact that even at 4K Ultra the system maintains 175 FPS average indicates that the RTX 4090's immense compute resources are not fully saturated until the highest resolution and settings combination.

The Medium settings preset provides the only complete dataset with min and max FPS values. At 4K Medium, the system averages 244 FPS with a minimum of 208 FPS and maximum of 281 FPS. At 1440p Medium, the average rises to 432 FPS with min/max of 367/496. At 1080p Medium, the average reaches 647 FPS with min/max of 550/744. The gap between minimum and maximum FPS narrows slightly as resolution decreases, suggesting that frame time consistency improves at lower resolutions where the GPU is less stressed. The high minimum FPS values across all resolutions indicate that this combination rarely experiences significant frame drops, even when the GPU is pushed to 4K.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It operates with a base clock of 3.70 GHz and a boost clock of 4.70 GHz, built on TSMC's 5 nm process node. The processor features a 32 MB shared L3 cache, with 64 KB L1 and 1 MB L2 per core. Its benchmark scores show strong single-threaded performance, with a Cinebench R23 single-core score of 3072 and a multi-core score of 21765. The PassMark single-thread score of 3689 places it in the 83rd percentile among all CPUs tested.

In the context of Roblox, the CPU's role is primarily to feed the GPU with draw calls and game logic updates. The measured FPS data shows that at 1080p Low, the system reaches 711 FPS, which is likely near the CPU's practical limit for this game engine. The fact that the FPS scales so dramatically between 1080p and 4K — from 711 to 268 FPS at Low settings — indicates that the GPU becomes the primary bottleneck at higher resolutions. At 1080p, however, the CPU's 6 cores and 12 threads with a 4.70 GHz boost clock appear sufficient to push frame rates well beyond what most displays can show.

The Ryzen 5 7400F's nearest rivals in the database include the Intel Core i5-14600T with a 0.1% higher average score, the Intel Core Ultra 7 155H with a 0.2% higher score, and the AMD Ryzen 7 PRO 6850H with a 0.2% lower score. These margins are negligible, meaning the 7400F's CPU performance is essentially on par with these alternatives. For Roblox specifically, the CPU's single-thread performance is likely more critical than multi-thread, given the game's typical scope and the high frame rates observed. The Cinebench R15 single-core score of 309 and R20 single-core score of 1290 demonstrate solid per-core capability that supports the high FPS at lower resolutions.

Settings Recommendations

Examining the measured FPS across the four settings presets, the data reveals that even the most demanding Ultra preset delivers playable performance at every resolution. At 4K Ultra, the system averages 175 FPS, which exceeds the refresh rate of most high-end monitors. The Ultra preset at 1440p delivers 310 FPS, and at 1080p it reaches 464 FPS. Given that the minimum FPS at 4K Medium is 208, it is reasonable to infer that Ultra settings would maintain a minimum above 150 FPS based on the average-to-minimum ratio observed in the Medium preset.

However, the data suggests that the Medium preset offers the most balanced experience. At 1080p Medium, the system averages 647 FPS with a minimum of 550 FPS, providing a substantial buffer above even the fastest gaming monitors. At 1440p Medium, the 432 FPS average with a 367 FPS minimum ensures no visible stuttering on any current display technology. The 4K Medium preset's 244 FPS average and 208 FPS minimum are more than sufficient for 4K gaming, and the visual quality improvement from Low to Medium is typically more noticeable than the jump from Medium to High or Ultra.

The Low preset delivers the highest frame rates — 711 FPS at 1080p, 474 FPS at 1440p, and 268 FPS at 4K — but these numbers exceed what any display can actually show. For competitive play where response time is paramount, the Low preset at 1440p or 1080p might be preferred, as the higher FPS can reduce input latency. However, for most players, the Medium preset at 1440p provides an optimal balance: 432 FPS average is far above any monitor's refresh rate, and the visual fidelity improvement over Low is significant. The Ultra preset, while playable, offers diminishing returns for the FPS cost, particularly at 4K where the drop from Medium to Ultra is 69 FPS on average.

How This Combo Ranks

The combination of the AMD Ryzen 5 7400F and NVIDIA GeForce RTX 4090 achieves a combo rank of 135 out of 3010 tested combinations in Roblox. This places the system in the top 4.5% of all tested configurations, indicating that this pairing is exceptionally well-suited for this game. The rank reflects the measured FPS data, which shows the system delivering over 170 FPS even at the most demanding 4K Ultra preset.

The RTX 4090's individual percentile ranking is 88th among all GPUs, with an average benchmark score of 60347. Its nearest rivals include the Intel Arc Pro A60 with a 0% delta, the AMD Radeon Pro Vega 48 with a 0.3% higher score, and the AMD Radeon Pro W6600M with a 2.5% lower score. These rival comparisons are based on synthetic benchmark averages rather than Roblox-specific performance, so the actual in-game ranking may differ. The CPU's 83rd percentile ranking and the GPU's 88th percentile ranking combine to produce a system that ranks in the 135th spot overall, suggesting that the pairing is synergistic for Roblox's specific workload.

Given that Roblox is a sandbox game with significant CPU-bound scenarios, the Ryzen 5 7400F's strong single-thread performance contributes meaningfully to the overall rank. The fact that this combo outperforms 2,875 other tested combinations indicates that the balanced nature of this pairing — a capable mid-range CPU with a top-tier GPU — yields excellent results in this title. The rank of 135 out of 3010 also implies that there are 134 combinations that achieve higher FPS, likely featuring faster CPUs such as higher-core-count Ryzen 7000 or Intel 14th-gen parts, but the difference in real-world playability is minimal given the already extreme frame rates.

GPU Role

The NVIDIA GeForce RTX 4090 is built on the Ada Lovelace architecture using TSMC's 5 nm process, featuring the AD102 chip with 76,300 million transistors on a 609 mm² die. It operates with a base clock of 2235 MHz and a boost clock of 2520 MHz, with memory clocked at 1313 MHz (21 Gbps effective). The GPU includes 24 GB of GDDR6X memory on a 384-bit bus, providing 1.01 TB/s of memory bandwidth. Its compute capabilities include 16384 shading units, 512 TMUs, 176 ROPs, 128 RT cores, and 512 tensor cores, delivering 82.58 TFLOPS of FP32 performance.

In Roblox, the GPU's role becomes increasingly dominant as resolution increases. The measured FPS data shows that at 1080p Low, the system achieves 711 FPS, which is likely constrained more by the CPU's ability to issue draw calls than by the GPU's rendering capability. As resolution increases to 1440p and 4K, the GPU's pixel throughput becomes the limiting factor. The RTX 4090's 24 GB of VRAM is far more than Roblox requires, and the memory bandwidth of 1.01 TB/s ensures that texture streaming and asset loading are never bottlenecks. The high boost clock of 2520 MHz contributes to the GPU's ability to maintain high frame rates even at 4K Ultra, where it still delivers 175 FPS.

The GPU's benchmark results show a PassMark G3D score of 38194, placing it in the 88th percentile among all GPUs. Its 3DMark Steel Nomad DX12 score of 9223 and Geekbench Vulkan score of 271631 reflect its strong general compute and graphics performance. The nearest GPU rivals in terms of average benchmark score include the Intel Arc Pro A60 (0% delta), AMD Radeon Pro Vega 48 (0.3% higher), and AMD Radeon PRO V710 (2.9% higher), though these are workstation GPUs with different performance profiles. For Roblox specifically, the RTX 4090's raw rasterization performance is what drives the high FPS at 4K, and the data shows that even the most demanding settings preset cannot fully saturate this GPU at 1080p.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all relevant resolution and settings combinations. At 1920x1080, the system delivers 711 FPS at Low, 647 FPS at Medium (min 550, max 744), 572 FPS at High, and 464 FPS at Ultra. The spread between Low and Ultra at 1080p is 247 FPS, representing a 35% performance penalty for the highest visual quality. The Medium preset's minimum FPS of 550 is remarkably high, suggesting excellent frame pacing.

At 2560x1440, the performance scales down accordingly: 474 FPS at Low, 432 FPS at Medium (min 367, max 496), 382 FPS at High, and 310 FPS at Ultra. The gap between Low and Ultra narrows to 164 FPS (35% penalty), which is proportionally similar to the 1080p results. The 1440p Medium preset maintains a minimum of 367 FPS, which is still far above any mainstream monitor's refresh rate.

At 3840x2160, the system delivers 268 FPS at Low, 244 FPS at Medium (min 208, max 281), 216 FPS at High, and 175 FPS at Ultra. The performance penalty from Low to Ultra is 93 FPS (35%), consistent with the other resolutions. The 4K Medium preset's minimum FPS of 208 ensures that even the most demanding scenes remain above 200 FPS. Overall, the data shows that this configuration never drops below 175 FPS in any tested scenario, making it suitable for the highest refresh rate displays available.
