Roblox

Roblox is a sandbox title where the measured performance of the Intel Core i5-14600KF paired with the AMD Radeon RX 6600 XT reveals a system that scales predictably across resolutions, with the data indicating a balance between CPU and GPU capabilities that shifts depending on the preset. The benchmark results place this combination at rank 2647 out of 3711 tested combos, placing it in the lower half of the database, which reflects a capable but not top-tier configuration for this specific game. The analysis below breaks down the measured FPS across three resolutions and four settings presets, interpreting what those numbers mean for the system's limiting components and overall suitability.

Resolution Scaling

The measured FPS data shows a clear and consistent downward trend as resolution increases, which is a classic indicator of the GPU becoming a more significant factor at higher pixel counts. At 1080p, the average frame rates are exceptionally high, ranging from 200 FPS on Ultra to 307 FPS on Low, suggesting that the system is rarely constrained by the graphics card at this resolution. The jump from Low to Ultra at 1920x1080 represents a drop of 107 FPS, or a 34.9% reduction, which while substantial, still leaves the system with headroom above typical high-refresh-rate monitor capabilities.

Moving to 2560x1440, the performance degrades in a linear fashion, with the average FPS dropping to between 134 (Ultra) and 205 (Low). The delta between the lowest and highest presets narrows to 71 FPS, indicating that the GPU is beginning to take on more work, but the CPU still has enough headroom to feed it effectively. The scaling from 1080p to 1440p at High settings shows a 33.2% reduction in average FPS (from 247 to 165), which is a significant hit but one that keeps the experience smooth on most displays.

The most telling data appears at 3840x2160, where the average FPS falls to between 76 (Ultra) and 116 (Low). The gap between Low and Ultra at 4K is only 40 FPS, the smallest absolute difference across all resolutions, which strongly suggests that the GPU is now the primary limiting factor. The transition from 1440p High (165 FPS) to 4K High (93 FPS) is a 43.6% drop, a steep decline that underscores the RX 6600 XT's 8 GB memory and 256.0 GB/s bandwidth being pushed to their limits. The data shows that at 1080p, the CPU is the bottleneck, while at 4K, the GPU dominates the performance equation.

GPU Role

The AMD Radeon RX 6600 XT, built on the RDNA 2.0 architecture with a Navi 23 chip, plays a decisive role in the higher-resolution results. Its 8 GB of GDDR6 memory on a 128-bit bus provides a bandwidth of 256.0 GB/s, which appears sufficient for Roblox's art style at 1440p but becomes a constraint at 4K. The GPU's clock speeds are notably high, with a base clock of 1968 MHz and a boost clock of 2589 MHz, and the game clock is rated at 2359 MHz, which helps maintain solid performance in a game that is not overly demanding on raw shader throughput.

The benchmark scores for the GPU show a 3DMark Steel Nomad DX12 score of 1804 and a PassMark G3D score of 16461, placing it in the 70th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 1630, which it leads by 0.7%, and the Intel Arc A350M, which leads it by 0.8%. This places it in a competitive mid-range tier, but the data indicates that at 4K, the GPU's memory bandwidth and capacity are the limiting factors, as evidenced by the significant FPS drop from 1440p to 2160p.

The GPU's FP32 performance of 10.60 TFLOPS and pixel rate of 165.7 GPixel/s are adequate for the game, but the 4K results suggest that the 8 GB memory pool is the primary bottleneck. The measured FPS at 4K High (93 FPS) versus 1440p High (165 FPS) shows a 43.6% reduction, which is disproportionately large compared to the pixel count increase of 125%, indicating that the GPU is not scaling efficiently at higher resolutions. This is typical for a card with a 128-bit memory interface, where the bandwidth per pixel decreases as resolution climbs.

How This Combo Ranks

The combo's rank of 2647 out of 3711 tested configurations places it in the 28.7th percentile for Roblox, which is a modest standing given the hardware involved. This ranking suggests that while the system is far from the bottom, it is also not among the high performers for this specific game, likely due to the GPU's mid-range positioning and the game's optimization patterns. The CPU, which ranks in the 90th percentile of all CPUs, is a strong contributor, but the GPU's 70th percentile standing drags the overall combo down in a game that becomes GPU-bound at higher resolutions.

The nearest rival CPUs for the i5-14600KF include the AMD Ryzen 9 7900, which scores 0.3% higher, and the AMD Ryzen 7 PRO 5755G, which scores 0.4% higher, indicating that the CPU is highly competitive and not the source of the combo's lower ranking. On the GPU side, the RX 6600 XT is closely matched with the NVIDIA GeForce GTX 1630 (0.7% higher for AMD) and the Intel Arc A350M (0.8% lower for AMD), showing that the card is in a tight performance band where small differences in game optimization can shift rankings.

The combo rank of 2647 indicates that there are 1064 tested configurations that perform worse, which does position this system above a significant portion of the database. However, for a user with a high-refresh-rate display, the 1080p and 1440p results are more than adequate, and the rank likely reflects the 4K performance where the GPU falls short of top-tier cards. The data suggests that this combo is well-suited for 1080p and 1440p gaming, but not for 4K enthusiasts.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all presets. The Low preset averages 307 FPS, while Medium averages 279 FPS with a minimum of 238 FPS and maximum of 321 FPS, showing tight frame pacing. High averages 247 FPS, and Ultra averages 200 FPS. The spread from Low to Ultra is 107 FPS, and the Medium preset's minimum of 238 FPS is still higher than the Ultra average, indicating that the CPU is the primary driver at this resolution.

At 2560x1440, the performance remains strong but begins to show GPU influence. Low averages 205 FPS, Medium averages 187 FPS with a minimum of 159 FPS and maximum of 214 FPS, High averages 165 FPS, and Ultra averages 134 FPS. The delta between Low and Ultra is 71 FPS, and the Medium minimum of 159 FPS is comfortably above 144 Hz refresh rates, making this resolution well-suited for high-refresh gaming.

At 3840x2160, the GPU becomes the clear bottleneck. Low averages 116 FPS, Medium averages 105 FPS with a minimum of 90 FPS and maximum of 121 FPS, High averages 93 FPS, and Ultra averages 76 FPS. The Medium preset's minimum of 90 FPS is the only measurement below 100 FPS in the entire dataset, and the Ultra preset at 76 FPS is the only average below 90 FPS. The scaling from 1080p to 4K at Ultra shows a 62% drop in average FPS (from 200 to 76), which is a steep decline that highlights the GPU's limitations at this resolution.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p displays with 240 Hz refresh rates, the High preset at 247 FPS is the best balance, as it delivers frame rates that exceed most monitor capabilities while providing better visual fidelity than Low or Medium. The Ultra preset at 200 FPS is also viable for 240 Hz displays, but the 47 FPS drop from High to Ultra may not justify the visual gains for all users.

For 1440p displays with 144 Hz or 165 Hz refresh rates, the High preset at 165 FPS is the clear recommendation, as it hits the target refresh rate without exceeding the GPU's capabilities. The Medium preset at 187 FPS offers a higher margin, but the visual quality difference is minimal and the High preset provides a better experience for most users. The Ultra preset at 134 FPS is acceptable for 144 Hz displays but falls short of 165 Hz, so High is the preferred choice.

For 4K displays, the situation is more constrained. The Low preset at 116 FPS and Medium preset at 105 FPS are the only options that provide smooth performance above 100 FPS, with Medium offering a minimum of 90 FPS. The High preset at 93 FPS is playable but close to the 90 FPS threshold, while Ultra at 76 FPS may exhibit noticeable drops on fast-moving scenes. The data supports using Medium at 4K for the best balance of visual quality and frame rate stability, as it offers a 12.9% higher average than High and a 27.6% higher average than Ultra.

CPU Role

The Intel Core i5-14600KF is a formidable processor for Roblox, with 14 cores and 20 threads that provide substantial multi-threaded headroom, though the game's engine may not fully utilize all of them. Its base clock of 3.50 GHz and boost clock of 5.30 GHz are high, and the 24 MB of shared L3 cache helps with single-threaded performance, which is critical for a game like Roblox that often has physics and scripting workloads. The CPU's Cinebench R23 multi-core score of 32544 and single-core score of 4594 place it in the 90th percentile of all CPUs, indicating excellent processing power.

The CPU's nearest rivals, such as the AMD Ryzen 9 7900 and Intel Core Ultra 5 245, score within 0.8% of it, showing that it is at the top of its class for this generation. The PassMark single-thread score of 4273 and multi-thread score of 38697 reinforce its capability, and the data suggests that the CPU is rarely the limiting factor in Roblox, except at 1080p where frame rates exceed 300 FPS. The measured FPS at 1080p Low (307 FPS) and Medium (279 FPS) indicates that the CPU can drive the GPU to its maximum output at this resolution, but the GPU becomes the bottleneck as resolution increases.

The CPU's 125 W TDP and support for DDR4 and DDR5 memory give it flexibility, but the benchmark data shows that its raw compute power is more than sufficient for Roblox. The fact that the combo ranks in the 28.7th percentile despite the CPU's top-tier standing suggests that the GPU is the primary constraint on overall performance, and upgrading the GPU would yield more significant gains than a CPU upgrade. The CPU's role is to maintain high minimum frame rates, which it does admirably, as evidenced by the Medium preset's minimum FPS of 238 at 1080p and 159 at 1440p, both of which are well above playable thresholds.
