Roblox

The Intel Core i7-14700KF and AMD Radeon RX 580 pairing presents a stark contrast in computational pedigree within the Roblox benchmark suite. The CPU is a modern 20-core, 28-thread Raptor Lake Refresh part, boosting up to 5.60 GHz, while the GPU is a 2017-era Polaris architecture card with 8 GB of GDDR5 memory. This discrepancy defines the performance envelope, as the data indicates the RX 580 becomes the primary bottleneck at higher resolutions, while the i7-14700KF ensures the frame rates remain playable even under extreme settings.

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

The Intel Core i7-14700KF is a high-end desktop processor with 20 cores and 28 threads, built on a 10 nm process. Its base clock of 3.40 GHz can scale up to a 5.60 GHz boost, providing substantial single-thread headroom that is critical for Roblox’s physics and game logic. The CPU’s benchmark scores reflect its dominance; it achieved 44,557 points in Cinebench R23 multi-core and 6,290 in single-core tests. This positions the chip in the 96th percentile of all CPUs, indicating top-tier performance for any workload.

In the context of Roblox, the CPU’s role is to feed the GPU with draw calls and manage the simulation. The data shows that the i7-14700KF is more than capable of this task. At 1080p Low settings, the combo reaches 164.7 FPS, which is near the practical ceiling for many displays. The processor’s high single-core score of 4,480 in Passmark suggests that even the most demanding Roblox worlds, which often rely on a single main thread, will not be CPU-limited. The nearest rival, the Intel Core i7-14700K, shows a delta of 0% in average score, confirming that the unlocked "KF" variant offers virtually identical computational performance, with the only difference being the lack of integrated graphics in the KF model.

The 33 MB of shared L3 cache is another factor; it provides a large pool of fast memory for frequently accessed data, reducing latency in complex scenes. While Roblox is not typically a cache-sensitive title compared to heavy simulation games, the sheer processing power available means the CPU rarely becomes a limiting factor. The benchmark results indicate that even at 4K Ultra, where the GPU is heavily strained, the CPU has enough headroom to maintain a 39.9 FPS average, suggesting the frame rate is governed by the graphics card, not the processor.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 580 is an older graphics card based on the GCN 4.0 architecture with a 14 nm process. It features 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. Its boost clock is rated at 1340 MHz, and it delivers a computed 6.175 TFLOPS of FP32 performance. Despite its age, the card holds a 53rd percentile ranking among all GPUs, showing it remains a mid-range contender for older or less demanding titles.

For Roblox, the RX 580’s performance is heavily dependent on settings. The data shows a clear scaling pattern: at 1080p High, the card manages 132.8 FPS, which drops to 106.8 FPS at Ultra. This indicates that the card is still capable at lower resolutions, but the gap between settings widens as resolution increases. The GPU’s pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s are modest by modern standards, yet they are sufficient for Roblox’s stylized graphics. However, the card’s nearest rivals include the NVIDIA GeForce GTX 570 and GTX 950, with delta percentages of 0% and 0.1%, respectively, placing it in performance parity with those older chips.

The 8 GB VRAM is a critical asset; at 4K Ultra, the GPU is likely approaching its memory limits, which explains the significant FPS drop to 39.9. In contrast, at 4K Low, the card achieves 60.6 FPS, showing that reducing texture quality and effects relieves memory pressure and shader load. The GPU’s DirectX 12 score of 43 in Passmark is notably low, but Roblox’s engine often utilizes older API paths, where the card’s DirectX 11 score of 60 is more relevant. Ultimately, the RX 580 acts as the limiting component in this pairing, preventing the powerful CPU from reaching its full potential at higher resolutions.

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

The measured FPS data reveals a classic GPU-bound scenario. Moving from 1080p to 4K, the frame rates drop dramatically across all settings. At High settings, the average FPS falls from 132.8 at 1080p to 87.2 at 1440p, and finally to 51.8 at 4K. This represents a 61% reduction in frame rate from 1080p to 4K, a clear indication that the RX 580’s rendering throughput is the bottleneck, not the CPU.

The scaling is even more pronounced at Ultra settings. The combo drops from 106.8 FPS at 1080p to 73.7 FPS at 1440p, and then plummets to 39.9 FPS at 4K. The performance hit from 1440p to 4K is about 46%, showing that the GPU’s fill rate and memory bandwidth are insufficient for the increased pixel count. In contrast, the CPU’s performance is nearly constant regardless of resolution, as its workload does not increase with pixel count.

This pattern indicates that the i7-14700KF is not the limiting component. If the CPU were the bottleneck, the FPS would remain similar across resolutions. Instead, the data shows a consistent decline, which is the hallmark of a GPU-limited system. The fact that the RX 580 can still push 51.8 FPS at 4K High reflects its 8 GB frame buffer, but the 39.9 FPS at 4K Ultra suggests that the card’s 32 ROPs and 6.175 TFLOPS are simply not enough for maximum settings at 4K. For users targeting 1080p, the combo is excellent, but for 4K gaming, the GPU must be upgraded to match the CPU’s potential.

How This Combo Ranks — use comboRankInGame vs other tested combos

Within the benchmark database, this specific combination of the Intel Core i7-14700KF and AMD Radeon RX 580 ranks 1678th out of 1800 tested combos for Roblox. This places it in the bottom 10% of all system configurations, which is surprising given the CPU’s high performance. The low ranking is almost entirely due to the GPU’s age and limited performance ceiling.

The combo rank of 1678 indicates that a vast majority of other systems, including those with weaker CPUs but more modern GPUs, achieve higher frame rates. This is because Roblox is a GPU-bound title at higher settings, and the RX 580’s performance is significantly lower than many modern mid-range cards. The data suggests that pairing a top-tier CPU with an entry-level-to-midrange GPU from 2017 creates a severe imbalance. While the CPU ensures the system can handle complex physics and large worlds, the GPU fails to translate that into higher visual fidelity or frame rates.

The percentile rankings reinforce this. The CPU’s 96th percentile does not compensate for the GPU’s 53rd percentile, and the overall system performance is dragged down. The nearest rival GPUs, such as the GTX 950, show that the RX 580 is competitive with older, lower-tier cards, but not with anything modern. For a game like Roblox, which can be CPU-intensive in specific scenarios, this combo might perform better than the rank suggests in single-threaded situations, but the average FPS across settings is what drives the rank down. The data clearly shows that the GPU is the weak link, and the overall rank reflects that reality.
