Settings Recommendations

For this pairing, the measured data points to Medium as the optimal settings tier across all tested resolutions. The pattern is consistent: Medium delivers a substantial frame rate increase over High while maintaining a measurable minimum FPS, which is the only settings row that reports both minimum and maximum values in the dataset. At 1920x1080, Medium produces 647 FPS average with a 550 FPS minimum, versus High's 572 FPS average with no reported minimum. The gap between Medium and Low is smaller — 647 FPS versus 711 FPS at 1080p — but the Low preset's lack of a reported minimum suggests that stability data is incomplete for that tier.

At 2560x1440, Medium again represents the balanced choice: 432 FPS average with a 367 FPS minimum, while High trails at 382 FPS and Low leads at 474 FPS. The 1440p Medium result shows only an 8 FPS drop in the minimum compared to the 1080p Medium minimum, indicating that the frame pacing remains consistent as resolution climbs. At 3840x2160, Medium delivers 244 FPS average with a 208 FPS minimum, which is still far above display refresh rate capabilities for most monitors. The Ultra preset, while visually demanding, drops to 175 FPS at 4K and 464 FPS at 1080p — a significant step down from Medium's 647 FPS at the same resolution.

The data suggests that the Medium preset is the sweet spot because it offers the best compromise between visual fidelity and frame rate headroom. High settings cost roughly 12% of average FPS at 1080p (572 versus 647), while Ultra costs nearly 28% (464 versus 647). Given that this combination of CPU and GPU is capable of producing frame rates far beyond typical display capabilities, the Medium preset's higher averages and reported minimums make it the recommended starting point. Users seeking maximum visual quality can still use Ultra, but they will forfeit over 180 FPS at 1080p compared to Medium.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and the measured frame rates reflect its massive compute headroom. The GPU's 24 GB of GDDR6X memory on a 384-bit bus provides 1.01 TB/s of bandwidth, which is far more than Roblox's sandbox workloads require. The memory clock runs at 1313 MHz with 21 Gbps effective speed, while the GPU core operates at a 2235 MHz base and 2520 MHz boost clock. These specifications translate into an 82.58 TFLOPS FP32 compute rate, a 443.5 GPixel/s pixel rate, and a 1,290.2 GTexel/s texture rate.

The RTX 4090's benchmark scores confirm its position. It achieves a 38194 score in Passmark G3D and a 255416 score in Geekbench OpenCL, with a 271631 in Geekbench Vulkan. The GPU's percentileVsAllGpus of 88 places it in the top tier of all graphics cards, and its average benchmark score of 60347 is nearly identical to the Intel Arc Pro A60 (60326, 0% delta) and slightly ahead of the AMD Radeon Pro Vega 48 (60140, 0.3% delta). The data shows that in this Roblox configuration, the GPU is never the limiting factor — even at 4K Ultra, the average FPS of 175 is far above the thresholds where a GPU bottleneck would manifest.

The GPU's 176 ROPs and 512 TMUs handle Roblox's relatively simple geometry with ease. The architecture's 16384 shading units and 128 RT cores provide headroom that this game does not meaningfully exercise. The 450 W TDP and triple-slot cooler are overkill for a title that rarely stresses the GPU's full capability, but the measured results show that the RTX 4090's raw throughput is what enables the extraordinarily high frame rates observed in the dataset. The GPU's production status is end-of-life, which is notable given its performance remains at the top of the charts.

Resolution Scaling

The measured FPS data shows a clear scaling pattern as resolution increases. At 1080p Medium, the average is 647 FPS; at 1440p Medium, it drops to 432 FPS; and at 4K Medium, it falls to 244 FPS. This represents a 33% reduction from 1080p to 1440p, and a further 44% reduction from 1440p to 4K. The same proportional relationship holds across all settings tiers. For High settings, the progression is 572 FPS at 1080p, 382 FPS at 1440p, and 216 FPS at 4K — a 33% drop followed by a 43% drop. Low settings see 711 FPS at 1080p, 474 FPS at 1440p, and 268 FPS at 4K.

The scaling pattern indicates that the CPU is becoming more of a factor as resolution decreases, while the GPU remains the primary driver at higher resolutions. At 1080p, the frame rates are so high that the Intel Core i3-12100F's 4 cores and 8 threads may begin to limit the maximum achievable FPS. The 1080p Low result of 711 FPS is particularly telling — this is likely approaching the CPU's ceiling for this game's single-threaded workload. At 4K, the GPU's rasterization throughput becomes the binding constraint, with the RTX 4090's 443.5 GPixel/s pixel rate being exercised more fully.

The minimum FPS data, available only for Medium settings, reinforces this interpretation. At 1080p Medium, the minimum is 550 FPS; at 1440p Medium, it's 367 FPS; and at 4K Medium, it's 208 FPS. The minimum values scale proportionally with the averages, suggesting that frame pacing remains stable across resolutions. The 4K Medium minimum of 208 FPS is still well above the 144 Hz refresh rate common on high-end monitors, meaning this configuration can drive even the fastest displays without dipping below their refresh threshold.

FAQ

Q: What is the best resolution for this CPU/GPU combination in Roblox?

A: The data shows playable frame rates at all three tested resolutions. At 4K Medium, the average is 244 FPS with a 208 FPS minimum, which exceeds the refresh rate of most monitors. For maximum frame rates, 1080p Low delivers 711 FPS average, but the Medium preset's 647 FPS with a 550 FPS minimum offers a better balance.

Q: How does the Ultra preset compare to High and Medium?

A: Ultra is the most demanding tier in the dataset. At 1080p, Ultra averages 464 FPS versus High's 572 FPS and Medium's 647 FPS. At 4K, Ultra drops to 175 FPS, while High holds 216 FPS and Medium reaches 244 FPS. Ultra consistently costs 15-30% of average FPS compared to High across all resolutions.

Q: Is the RTX 4090 overkill for Roblox?

A: The benchmark results indicate extreme headroom. The GPU's 82.58 TFLOPS FP32 compute and 1.01 TB/s memory bandwidth are far beyond what Roblox requires. Even at 4K Ultra, the average FPS of 175 is over three times higher than a standard 60 Hz display's refresh rate. The RTX 4090's percentileVsAllGpus of 88 confirms its top-tier status.

Q: Does the Core i3-12100F bottleneck the RTX 4090 in this game?

A: At 1080p Low settings, the 711 FPS average suggests the CPU may be approaching its limit, given its 4 cores and 8 threads with a 4.30 GHz boost clock. However, at higher settings and resolutions, the GPU becomes the primary factor. The CPU's single-thread score of 893 in 3dmark and 1674 in Cinebench R23 indicate strong per-core performance for this class.

Q: What frame rate can I expect at 1440p with Medium settings?

A: The measured data shows a 432 FPS average with a 367 FPS minimum for 1440p Medium. This is the highest average among the settings that report minimum FPS values. Compared to 1080p Medium's 647 FPS, the 1440p result represents a 33% reduction, consistent with the resolution scaling pattern.

Q: How does the RTX 4090's benchmark score compare to its nearest rivals?

A: The RTX 4090's average benchmark score of 60347 is essentially tied with the Intel Arc Pro A60 (60326, 0% delta) and slightly ahead of the AMD Radeon Pro Vega 48 (60140, 0.3% delta). It trails the AMD Radeon Pro W6600M by 2.5% (61896) and beats the AMD Radeon PRO V710 by 2.9% (58657).

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from Intel's Core 12th Gen series, built on the Alder Lake architecture at a 10 nm process node. Its base clock is 3.30 GHz with a 4.30 GHz boost clock, and it draws 58 W TDP. The CPU's cache configuration includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. It supports both DDR4 and DDR5 memory in dual-channel configuration and connects via PCIe Gen 5 with 16 lanes.

In this Roblox configuration, the CPU's role becomes increasingly significant at lower resolutions and settings. The 3dmark benchmarks show a single-thread score of 893, which jumps to 1659 for 2 threads and 2859 for 4 threads. The 8-thread score of 4026 is nearly identical to the max-thread score of 4023, indicating that the processor's 8 threads are fully utilized in that test. The Cinebench R23 results show 1674 single-core and 11860 multi-core scores, while Geekbench reports 1932 single-core and 7252 multi-core.

The CPU's percentileVsAllCpus of 68 places it above most processors, though its average benchmark score of 13494 is nearly identical to the Intel Core 3 N355 (13492, 0% delta) and the Intel Core i5-9500 (13452, 0.3% delta). The nearest rivals show the Core i3-12100F performs within 1.1% of the Intel Core i7-1250U (13351) and within 0.7% of the Intel Core 5 120UL (13594). This mid-pack positioning means the CPU is capable but not exceptional, which aligns with the observed bottleneck potential at 1080p Low where the 711 FPS average may be CPU-limited.

The Passmark results reinforce this picture: single-thread performance is 3444, while multithread is 14015. The integer math score of 40978 and floating point score of 31977 indicate solid general-purpose compute, while the physics score of 985 and find prime numbers score of 60 show the CPU's limits in certain workloads. For Roblox, which tends to be lightly threaded, the single-thread performance of 893 in 3dmark is the most relevant metric, and it appears sufficient to drive frame rates well above 500 FPS at 1080p.

Measured FPS Breakdown

The dataset provides average FPS for all settings at three resolutions, with minimum and maximum values reported only for the Medium preset. At 1920x1080, the results are: Low settings average 711 FPS, Medium averages 647 FPS with a 550 FPS minimum and 744 FPS maximum, High averages 572 FPS, and Ultra averages 464 FPS. The spread between Low and Ultra at 1080p is 247 FPS, representing a 35% reduction from the highest to lowest settings tier.

At 2560x1440, the pattern shifts proportionally: Low averages 474 FPS, Medium averages 432 FPS with a 367 FPS minimum and 496 FPS maximum, High averages 382 FPS, and Ultra averages 310 FPS. The delta between Low and Ultra at 1440p is 164 FPS, which is a 35% reduction — identical to the 1080p percentage. The Medium preset's minimum of 367 FPS at 1440p is still above the 1080p Ultra average of 464 FPS, showing that resolution has a more pronounced effect than settings at this performance level.

At 3840x2160, the measurements are: Low averages 268 FPS, Medium averages 244 FPS with a 208 FPS minimum and 281 FPS maximum, High averages 216 FPS, and Ultra averages 175 FPS. The 4K Low result of 268 FPS is lower than the 1440p Ultra result of 310 FPS, demonstrating that the move from 1440p to 4K has a larger impact than moving from Ultra to Low settings at 1440p. The Medium preset at 4K shows a 208 FPS minimum, which is the lowest reported minimum across all tested configurations, but still comfortably above 144 Hz.

The Medium preset is the only one with complete minimum and maximum data, which provides insight into frame time consistency. At 1080p Medium, the spread between minimum and maximum is 194 FPS (550 to 744). At 1440p Medium, the spread narrows to 129 FPS (367 to 496). At 4K Medium, the spread is 73 FPS (208 to 281). This decreasing spread with increasing resolution suggests that the GPU's workload becomes more consistent at higher resolutions, reducing frame time variance. The combo's overall rank in Roblox is 144 out of 3711 tested combinations, placing it in the top 4% of all configurations measured for this game.
