# Roblox with Intel Core i5-12400 + NVIDIA GeForce RTX 5090 D

The combination of the Intel Core i5-12400 and NVIDIA GeForce RTX 5090 D produces exceptional frame rates in Roblox, with measured averages ranging from 191 FPS at 4K Ultra settings to 776 FPS at 1080p Low settings. This pairing ranks first overall among 3,010 tested combos in this game, indicating that the system delivers the highest measured performance in the database. The data shows a clear pattern where resolution and settings scaling reveal a system that remains GPU-bound at higher resolutions but transitions toward CPU limitation at lower resolutions and lighter settings.

Resolution Scaling

The measured FPS data reveals how performance scales across three resolutions: 1920x1080, 2560x1440, and 3840x2160. At High settings, the average frame rate drops from 625 FPS at 1080p to 417 FPS at 1440p, then to 236 FPS at 4K. This represents a 33% reduction from 1080p to 1440p and a further 43% reduction from 1440p to 4K. The scaling pattern indicates that the GPU becomes the limiting component as resolution increases, which is consistent with the RTX 5090 D's role in rendering pixel-heavy workloads.

At Low settings, the same resolution progression yields 776 FPS at 1080p, 518 FPS at 1440p, and 293 FPS at 4K. The percentage drops are larger in absolute terms but proportionally similar, with 1080p to 1440p showing a 33% decrease and 1440p to 4K showing a 43% decrease. The fact that Low settings still show substantial resolution scaling suggests that even at the lowest graphics quality, the GPU remains engaged, though the gap between 1080p and 1440p at Low settings (258 FPS difference) is smaller than at High settings (208 FPS difference).

Ultra settings show the steepest resolution penalties: 507 FPS at 1080p, 338 FPS at 1440p, and 191 FPS at 4K. The 4K Ultra result of 191 FPS is the lowest measured value in the entire dataset, yet it still comfortably exceeds typical display refresh rates. The resolution scaling at Ultra settings demonstrates a 62% performance reduction from 1080p to 4K, which is the largest drop across all settings tiers. This indicates that Ultra settings at 4K place the heaviest load on the GPU, while the CPU's contribution becomes relatively less significant.

Medium settings provide the only rows with min and max FPS values recorded. At 1080p Medium, the average is 706 FPS with a minimum of 600 FPS and maximum of 812 FPS. At 1440p Medium, the average drops to 471 FPS with a range of 401-542 FPS. At 4K Medium, the average is 267 FPS with a range of 227-307 FPS. The min-to-max spreads of approximately 200 FPS at 1080p, 141 FPS at 1440p, and 80 FPS at 4K suggest that frame time consistency improves as resolution increases, likely because the GPU workload becomes more dominant and smooths out CPU-side fluctuations.

How This Combo Ranks

The combo ranks first out of 3,010 tested combinations in Roblox, placing it at the top of the database for this game. This top ranking is notable because the RTX 5090 D's average benchmark score places it in the 92nd percentile among all GPUs, while the Core i5-12400 sits in the 72nd percentile among all CPUs. The GPU's high percentile ranking is the primary driver of this combo's dominance, though the CPU's mid-tier standing proves sufficient for the game's demands.

The GPU's average benchmark score of 77,712 places it near several competitors according to the nearestRivals data. The AMD Radeon RX 6650M XT scores 76,904, which is 1.1% lower, while the AMD Radeon RX 6850M XT scores 78,940, which is 1.6% higher. The NVIDIA Tesla P100 variants score 79,396 and 79,605, representing 2.1% and 2.4% advantages respectively. These margins are small in synthetic benchmarks, but the measured FPS in Roblox shows the RTX 5090 D delivering frame rates that no other combo in the database matches.

The CPU's average benchmark score of 18,683 places it close to several rivals. The AMD EPYC 7643 scores 18,697 (0.1% higher), the Intel Core i7-1355U scores 18,730 (0.3% higher), and the AMD Ryzen AI 5 330 scores 18,811 (0.7% higher). The Intel Core i3-14100F scores 18,519, which is 0.9% lower. These near-identical synthetic scores suggest that the i5-12400's performance profile is well-matched to this game's requirements, as it ranks first despite not having the highest raw CPU benchmark in its immediate comparison group.

The combination of a top-1% GPU with a mid-70s percentile CPU still produces the best measured result in Roblox, which indicates that the game's engine is not particularly demanding on processor resources at the settings tested. The data suggests that the RTX 5090 D's massive rendering capabilities are the decisive factor, while the i5-12400 provides sufficient throughput to avoid becoming a bottleneck at most resolution and settings combinations.

CPU Role

The Intel Core i5-12400 features 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture processor uses a 10 nm process node and has an 18 MB shared L3 cache. The CPU's 3DMark scores show scaling from 1,692 in the 2-thread test to 5,873 in the 16-thread test, with the max-thread score of 5,890 nearly matching the 16-thread result. This indicates that the processor's 12 threads are fully utilized by around 8-12 threads, beyond which performance gains flatten.

Cinebench results reinforce this picture, with the R23 multicore score of 15,989 and single-core score of 2,257. The ratio between these scores suggests that multithreaded workloads can extract roughly 7 times the performance of a single core, which is consistent with a 6-core/12-thread design. PassMark results show a multithread score of 18,747 and single-thread score of 3,456, with physics performance at 1,105. The data compression score of 226,908 and integer math score of 58,366 indicate strong general-purpose compute capabilities.

In Roblox specifically, the CPU's role appears secondary to the GPU. The measured FPS at 1080p Low settings reaches 776 FPS, which is likely approaching the game engine's frame rate ceiling or the CPU's ability to feed the GPU. The difference between 1080p Low (776 FPS) and 1080p High (625 FPS) is 151 FPS, while the difference between 1080p High and 1080p Ultra (507 FPS) is 118 FPS. These gaps suggest that even at 1080p, the GPU still has headroom, and the CPU is not severely limiting performance.

The i5-12400's 72nd percentile ranking among all CPUs places it above average but not elite. Its nearest rival, the AMD EPYC 7643, has nearly identical average scores (18,697 vs 18,683, a 0.1% difference), yet the EPYC is a server-class processor with far more cores. This underscores that Roblox's performance is not primarily dependent on core count or raw CPU throughput, but rather on the GPU's ability to render the game's relatively simple graphics quickly. The 2-thread 3DMark score of 1,692 and single-thread score of 910 suggest that the CPU's single-core performance is adequate for the game's physics and scripting workloads.

GPU Role

The NVIDIA GeForce RTX 5090 D is a massive GPU with 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. Its Blackwell 2.0 architecture uses a 5 nm process from TSMC and contains 92,200 million transistors on a 750 mm² die. The GPU operates at a base clock of 2017 MHz and boost clock of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). The shading unit count of 21,760 and 680 tensor cores provide substantial compute throughput, with FP32 performance rated at 104.8 TFLOPS.

In Roblox, the GPU's role is clearly dominant. The measured performance at 1080p Low settings reaches 776 FPS, which is likely near the practical ceiling for the game's rendering pipeline. The GPU's 92nd percentile ranking among all GPUs explains why this combo achieves the top rank in the game. The RTX 5090 D's average benchmark score of 77,712 is only slightly different from its nearest rivals, yet the measured FPS in Roblox still leads the database, suggesting that the game's workload favors this GPU's specific architecture.

The GPU's rendering capabilities become more apparent at higher resolutions. At 4K Ultra, the combo still delivers 191 FPS, which would be considered excellent for most games, but represents a 75% reduction from the 1080p Low result. The 32 GB VRAM is far more than Roblox requires, but the immense memory bandwidth of 1.79 TB/s helps maintain high frame rates at 4K. The GPU's passmark DirectX scores show 434 for DirectX 9, 371 for DirectX 11, and 219 for DirectX 12, with a G3D score of 44,065 and compute score of 28,396.

The RTX 5090 D's nearest rivals in synthetic benchmarks show interesting comparisons. The AMD Radeon RX 6850M XT scores 1.6% higher on average, yet this combo still outperforms any other in Roblox. The Tesla P100 variants score 2.1-2.4% higher on average, but these are datacenter-oriented GPUs without the same gaming-focused feature set. The data suggests that raw benchmark scores do not perfectly predict Roblox performance, and the RTX 5090 D's combination of high clock speeds, massive memory bandwidth, and modern architecture delivers exceptional results in this title.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's display resolution and refresh rate. At 1920x1080, all settings tiers deliver well above 500 FPS on average. The Ultra preset at 1080p achieves 507 FPS, which is sufficient for even the highest refresh rate monitors available. However, users with 240 Hz displays could opt for High settings at 625 FPS or Medium at 706 FPS to gain additional headroom. Low settings at 776 FPS provide the maximum frame rate but may not be visually optimal.

At 2560x1440, the Ultra preset delivers 338 FPS, which remains exceptionally high. High settings offer 417 FPS, Medium provides 471 FPS, and Low reaches 518 FPS. All 1440p settings exceed 300 FPS, making this resolution a sweet spot for high-refresh-rate gaming. The data shows that even at 1440p Ultra, the combo maintains frame rates that would fully saturate a 240 Hz display, with 338 FPS providing 98 FPS of headroom above that threshold.

At 3840x2160, the recommendations shift. Ultra settings deliver 191 FPS, which is still above 144 Hz display capabilities but may not satisfy users with 240 Hz monitors. High settings at 236 FPS provide a better balance for 240 Hz displays, while Medium at 267 FPS offers additional margin. Low settings at 293 FPS would maximize frame rate but may compromise visual quality. For 4K users with 120 Hz displays, any setting tier works, as even Ultra at 191 FPS exceeds 120 FPS.

The measured min and max FPS values at Medium settings provide insight into frame time consistency. At 1080p Medium, the 600 FPS minimum ensures no drops below 600 FPS, which is well above typical display refresh rates. At 1440p Medium, the 401 FPS minimum still provides a large safety margin. At 4K Medium, the 227 FPS minimum is the lowest recorded, but it remains above 144 Hz. These minimums suggest that Medium settings offer the most consistent performance across all resolutions.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are as follows: Low settings produce 776 FPS, Medium settings produce 706 FPS with a range of 600-812 FPS, High settings produce 625 FPS, and Ultra settings produce 507 FPS. This represents a 35% reduction from Low to Ultra at 1080p. The Medium setting's minimum of 600 FPS indicates that even in the most demanding scenes, the frame rate stays exceptionally high.

At 2560x1440, the average FPS values are 518 FPS for Low, 471 FPS for Medium (with a range of 401-542 FPS), 417 FPS for High, and 338 FPS for Ultra. The drop from Low to Ultra at 1440p is 35%, matching the 1080p scaling pattern. The Medium setting's minimum of 401 FPS still exceeds the maximum refresh rate of most gaming monitors.

At 3840x2160, the average FPS values are 293 FPS for Low, 267 FPS for Medium (with a range of 227-307 FPS), 236 FPS for High, and 191 FPS for Ultra. The reduction from Low to Ultra at 4K is 35%, consistent with the other resolutions. The Medium setting's minimum of 227 FPS at 4K is the lowest recorded minimum across all resolutions and settings, but it remains above 200 FPS.

Comparing across resolutions at the same settings: Low settings show a 62% reduction from 1080p to 4K (776 to 293 FPS), Medium settings show a 62% reduction (706 to 267 FPS), High settings show a 62% reduction (625 to 236 FPS), and Ultra settings show a 62% reduction (507 to 191 FPS). This consistent 62% scaling factor across all settings indicates that resolution affects performance uniformly, regardless of graphics quality level. The data also shows that the gap between Low and Ultra settings narrows as resolution increases: 269 FPS at 1080p, 180 FPS at 1440p, and 102 FPS at 4K. This suggests that at higher resolutions, the GPU's rendering workload becomes more uniform across settings, and the CPU-side differences between settings have less impact on overall performance.
