Roblox

Intel Core i5-14400F pairs with the AMD Radeon RX 570 to deliver a playable but heavily GPU-bound experience in Roblox, with the CPU’s 10 cores and 16 threads ensuring that even at 1080p Low settings, where the average frame rate peaks at 150.7 FPS, the processor is never the primary constraint. The combination’s overall rank of 1702 out of 1800 tested combos places it in the bottom 6% of all system configurations for this title, indicating that while the hardware is functional, it trails the vast majority of other setups in the database. Benchmark results show that the i5-14400F’s 10-core, 16-thread configuration, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz, provides ample headroom for Roblox’s typically light CPU load, leaving the RX 570’s 4 GB of GDDR5 memory and 2048 shading units as the decisive factor in frame rate delivery.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14400F, based on Raptor Lake architecture and built on a 10 nm process, brings 10 physical cores and 16 threads to the pairing. Its 20 MB of shared L3 cache and per-core L2 cache of 1.25 MB provide the memory hierarchy needed to feed the GPU without stalling, though Roblox’s modest computational demands mean the CPU’s single-threaded performance is rarely stressed. In Cinebench R23, the processor scores 3093 in single-core and 21914 in multi-core, while Geekbench reports 2333 single-core and 11209 multi-core scores, figures that place the chip in the 88th percentile of all CPUs. This high percentile explains why the measured FPS in Roblox scales almost entirely with resolution and graphics settings: the CPU is delivering far more throughput than the game requires, allowing the RX 570 to become the bottleneck.

At 1080p with Low settings, the combo reaches 150.7 FPS, which is the highest average recorded across all tested configurations. As settings increase to Medium, the average drops to 137.4 FPS, then to 119 FPS at High, and finally to 96.5 FPS at Ultra. This pattern of decline—roughly 8.8% from Low to Medium, 13.4% from Medium to High, and 18.9% from High to Ultra—shows that the GPU’s shading units and texture mapping units are being progressively overwhelmed, not the CPU’s 16 threads. The RX 570’s 128 TMUs and 32 ROPs, combined with a texture rate of 159.2 GTexel/s and pixel rate of 39.81 GPixel/s, are the limiting resources here; the CPU’s 4.70 GHz boost clock never approaches its ceiling in this workload.

The i5-14400F’s position relative to its nearest rivals reinforces its role as a non-factor in Roblox performance. It sits within 0.2% of the Intel Core i7-12800H and AMD Ryzen 5 PRO 7645 in average benchmark scores, and within 0.2% of the AMD Ryzen 7 250 and Intel Core i7-13705H, yet all four of those CPUs would produce nearly identical FPS in this game because the RX 570 dominates the frame time budget. The data suggests that upgrading the processor alone would yield no measurable improvement in Roblox; the GPU’s 14 nm Polaris 20 chip, with a boost clock of 1244 MHz and 5.095 TFLOPS of FP32 performance, is the sole arbiter of frame rates.

FAQ — 4-6 Q&A pairs answerable from FACT PACK data

Q: What is the highest average frame rate achieved by this CPU-GPU combo in Roblox, and at what settings?

A: The highest average frame rate is 150.7 FPS, recorded at 1920x1080 resolution with Low settings. This is the peak performance point for the combination, with all other settings and resolutions producing lower averages.

Q: How does the combo rank among all tested configurations in Roblox?

A: The Intel Core i5-14400F with AMD Radeon RX 570 ranks 1702 out of 1800 tested combos, placing it in the bottom 6% of all system configurations for this game. This rank reflects the GPU’s dated architecture rather than any CPU limitation.

Q: What is the lowest average frame rate, and under which conditions does it occur?

A: The lowest average frame rate is 39.1 FPS, observed at 3840x2160 resolution with Ultra settings. This represents a 74% drop from the peak 1080p Low result, demonstrating the GPU’s severe constraint at 4K.

Q: How does the CPU’s multi-core performance compare to its nearest rivals?

A: The i5-14400F scores 21914 in Cinebench R23 multi-core, placing it within 0.2% of the Intel Core i7-12800H and AMD Ryzen 5 PRO 7645, and within 0.2% of the AMD Ryzen 7 250 and Intel Core i7-13705H. This near-identical performance means any of these CPUs would yield similar Roblox results with the same GPU.

Q: Does the RX 570’s 4 GB memory capacity affect frame rates at higher resolutions?

A: At 3840x2160, the average frame rates fall to 57.3 FPS on Low, 53 FPS on Medium, 44 FPS on High, and 39.1 FPS on Ultra, with the 224.0 GB/s memory bandwidth and 256-bit bus width being insufficient to sustain higher throughput. The 4 GB GDDR5 capacity, combined with the GCN 4.0 architecture, creates a hard ceiling that no CPU can overcome.

Q: What is the FPS difference between Low and Ultra settings at 1440p?

A: At 2560x1440, Low settings produce 97.3 FPS, while Ultra settings drop to 62.6 FPS—a reduction of 35.7%—indicating that the GPU’s shading workload scales steeply with quality presets even at mid-range resolutions.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Resolution scaling in this combo reveals a textbook GPU-bound scenario. From 1920x1080 to 2560x1440, the High settings average drops from 119 FPS to 81.4 FPS, a 31.6% reduction that aligns closely with the pixel count increase of 77.8%, though the smaller percentage drop indicates some inefficiency in the GPU’s scaling. Moving from 1440p to 3840x2160, the High settings average falls further to 44 FPS, representing a 45.9% decrease from the 1440p figure—again, a smaller relative drop than the 125% pixel increase would suggest, implying that the RX 570’s 32 ROPs are not fully saturated until the highest resolutions.

The Low settings curve shows a similar pattern: 150.7 FPS at 1080p, 97.3 FPS at 1440p, and 57.3 FPS at 4K. This progression yields a 61.9% drop from 1080p to 4K, which is the largest relative decline across all settings, indicating that even at the lowest quality preset, the GPU’s fill rate and bandwidth become the limiting factor as resolution climbs. The Ultra settings curve is the steepest in absolute terms, falling from 96.5 FPS at 1080p to 62.6 FPS at 1440p to 39.1 FPS at 4K—a total 59.5% reduction—confirming that the GPU’s 5.095 TFLOPS of compute is exhausted well before the CPU’s capabilities are approached.

These scaling behaviors point decisively to the RX 570 as the bottleneck. The i5-14400F’s 88th percentile CPU ranking and consistent benchmark scores, including 25783 in Passmark multithread and 3723 in Passmark single-thread, would support much higher frame rates if the GPU were not the constraint. The fact that FPS drops by roughly 30-45% with each resolution step, regardless of settings, mirrors the GPU’s memory bandwidth ceiling of 224.0 GB/s and its 1168 MHz base clock, rather than any CPU-side limitation.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo delivers its strongest performance across all settings. Low settings average 150.7 FPS, Medium settings average 137.4 FPS, High settings average 119 FPS, and Ultra settings average 96.5 FPS. These figures show a consistent 10-15 FPS step between each quality tier, with the delta from Low to Ultra being 54.2 FPS, or 35.9% of the Low value. The 1080p results are the only resolution where the average exceeds 100 FPS on any setting, with Low and Medium both crossing that threshold.

At 2560x1440, performance drops substantially but remains playable. Low settings produce 97.3 FPS, Medium settings produce 92.2 FPS, High settings produce 81.4 FPS, and Ultra settings produce 62.6 FPS. The gap between Low and Medium narrows to just 5.1 FPS, or 5.2%, suggesting that the GPU’s texture units are already saturated at this resolution, while the gap from Medium to High expands to 10.8 FPS, and from High to Ultra expands further to 18.8 FPS, indicating that the shading workload grows non-linearly with quality presets.

At 3840x2160, the combo struggles to maintain smooth frame rates. Low settings average 57.3 FPS, Medium settings average 53 FPS, High settings average 44 FPS, and Ultra settings average 39.1 FPS. The drop from 1080p Low to 4K Low is 93.4 FPS, a 62% reduction, while the drop from 1080p Ultra to 4K Ultra is 57.4 FPS, a 59.5% reduction. At 4K, even the Low preset barely exceeds 60 FPS, and Ultra settings fall below 40 FPS, making the highest resolution usable only at the lowest quality settings. The data shows that this combo is best suited to 1080p gaming, with 1440p being borderline, and 4K only viable for Low or Medium presets.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Intel Core i5-14400F and AMD Radeon RX 570 combination ranks 1702 out of 1800 tested combos in Roblox, placing it in the bottom 5.4% of all configurations. This rank is a direct consequence of the GPU’s age: the RX 570, released in April 2017 with a 14 nm process and GCN 4.0 architecture, scores in the 74th percentile of all GPUs but is outclassed by nearly every modern graphics card in the database. The CPU, by contrast, ranks in the 88th percentile of all CPUs, yet its high standing cannot compensate for the GPU’s limitations in a game that is overwhelmingly GPU-bound.

The rank of 1702 means that 98 other tested combos perform worse than this pairing, while 1701 perform better. Given that the i5-14400F’s nearest CPU rivals—the Intel Core i7-12800H, AMD Ryzen 5 PRO 7645, AMD Ryzen 7 250, and Intel Core i7-13705H—all have average benchmark scores within 0.2% of this chip, swapping the CPU for any of these would not change the combo’s rank in Roblox; the RX 570 would still produce identical frame rates. Conversely, the GPU’s nearest rivals, including the NVIDIA GeForce RTX 5060 and AMD Radeon RX 7700 XT, have average scores within 0.2% of the RX 570, but these comparisons are misleading because those cards are far more capable in real-world gaming workloads.

The low rank is not a reflection of the CPU’s inadequacy but rather the GPU’s dated architecture. The RX 570’s 4 GB memory, 150 W TDP, and PCIe 3.0 x16 interface are all legacy specifications that limit performance in modern titles. In Roblox, the measured FPS data confirms that the GPU is the bottleneck at every resolution and setting, with the CPU’s 16 threads remaining underutilized throughout. For users seeking better performance, the data suggests that upgrading the GPU alone would yield significant gains, while upgrading the CPU would produce no measurable improvement in this game. The combo’s rank of 1702 out of 1800 is therefore a GPU-driven result, not a CPU-driven one, and it underscores the importance of balancing component generations when building a system for any game, including lightweight sandbox titles like Roblox.
