Roblox

The benchmark data for Roblox, paired with the Intel Core i5-12600KF and AMD Radeon RX 580, reveals a configuration that is heavily dependent on resolution and settings to maintain smooth performance. The measured frame rates show a system that is capable of high refresh rates at 1080p but begins to strain as pixel count increases, with the GPU emerging as the primary bottleneck in more demanding scenarios.

Resolution Scaling

The frame rate progression across resolutions clearly illustrates the shifting workload between the CPU and GPU. At 1920x1080 with High settings, the combo produces 134.2 FPS, which rises to 164.3 FPS when settings are dropped to Low. This indicates that at 1080p, the CPU and GPU have ample headroom, and the game’s performance is less constrained by the graphics card. The jump from Low to Medium settings at 1080p shows a modest decrease to 151.5 FPS, while Ultra settings bring the average down to 110.1 FPS.

Moving to 2560x1440, the scaling becomes more pronounced. High settings yield 88.4 FPS, a significant drop from the 134.2 FPS seen at 1080p. Low settings at 1440p maintain 107.9 FPS, but the gap between Low and High widens compared to 1080p, suggesting that the GPU is starting to feel the pressure of additional pixels. Ultra settings at 1440p fall to 72 FPS, which is a 34.6% reduction from the 110.1 FPS at 1080p Ultra. This trend indicates that the RX 580’s rendering capabilities are becoming the limiting factor as resolution increases.

At 3840x2160, the performance hit is substantial. High settings average 49.9 FPS, which is below the 60 FPS threshold often targeted for smooth gameplay. Low settings recover to 61.8 FPS, while Medium sits at 59.2 FPS. Ultra settings at 4K drop dramatically to 37.4 FPS. The data shows that from 1080p High to 4K High, the frame rate falls by 62.8%, a steep decline that points squarely at the GPU as the bottleneck. The CPU’s 10 cores and 16 threads, with a boost clock of 4.90 GHz, are unlikely to be the constraint at these higher resolutions; the RX 580’s 8 GB of GDDR5 memory and 256-bit bus are being saturated by the pixel workload.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the Core i5-12600KF and Radeon RX 580 ranks 1660 out of 1800 combos for Roblox. This places it in the lower percentile of all possible configurations, indicating that while it can play the game, it is far from the top tier in terms of overall performance. The rank reflects a balance where the CPU is significantly more powerful than the GPU in relative terms. The Core i5-12600KF sits at the 84th percentile among all CPUs, with an average benchmark score of 27827, placing it near the Intel Core i9-10900K (which scores 27829, a 0% delta) and just ahead of the Intel Core i5-12600K (27851, a -0.1% delta). This is a high-performing processor.

However, the GPU tells a different story. The RX 580 is at the 53rd percentile among all GPUs, with an average benchmark score of 13559. Its nearest rivals include the NVIDIA GeForce GTX 570 (13564, 0% delta) and the NVIDIA GeForce GTX 950 (13549, 0.1% delta). The pairing of a top-quartile CPU with a mid-pack GPU creates an imbalance that is reflected in the combo’s low rank. The data suggests that for Roblox, the system’s overall capability is dragged down by the GPU’s performance, which is below the median when compared to other graphics cards. The low combo rank is a direct consequence of this mismatch, where the CPU’s potential is left untapped at higher resolutions.

GPU Role

The AMD Radeon RX 580 is built on the Polaris 20 chip using a 14 nm process from GlobalFoundries. It features 2304 shading units, 144 texture mapping units, and 32 ROPs. The GPU operates at a base clock of 1257 MHz and a boost clock of 1340 MHz, with memory running at 2000 MHz (8 Gbps effective). The 8 GB of GDDR5 memory on a 256-bit bus provides a bandwidth of 256.0 GB/s. These specifications define its performance envelope in Roblox.

In this game, the GPU’s role is critical at higher resolutions. The measured FPS data shows that at 4K Ultra, the average drops to 37.4 FPS, which is a 66% reduction from the 1080p Ultra score of 110.1 FPS. This severe scaling is indicative of the GPU hitting its limits in terms of fill rate and memory bandwidth. The RX 580’s pixel rate is 42.88 GPixel/s, and its texture rate is 193.0 GTexel/s. In Roblox, which often involves simple geometry but can have complex draw calls, the 32 ROPs become a bottleneck at 4K. The GPU’s FP32 performance of 6.175 TFLOPS is adequate for the game’s shader complexity, but the sheer number of pixels at 3840x2160 overwhelms the rendering pipeline. The data indicates that the RX 580 is best utilized at 1080p or 1440p, where its scores remain playable, but it is not suited for 4K beyond Low settings. The GPU’s average benchmark score of 13559 places it near the GeForce GTX 570, which is an older architecture, reinforcing that it is a mid-range part from its era.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture, manufactured on a 10 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.90 GHz. The CPU’s cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. It supports dual-channel DDR4 and DDR5 memory and has 20 PCIe Gen 4 lanes. In terms of raw compute, it scores 23444 in Cinebench R23 multi-core and 3309 in single-core, with a Passmark multithread score of 27575.

In Roblox, the CPU’s role is to handle game logic, physics, and draw calls. The game is known to be more CPU-intensive at lower resolutions, where the GPU is not the limiting factor. The data supports this: at 1080p Low, the combo reaches 164.3 FPS, which is the highest average in the dataset. This suggests the CPU can feed the GPU with enough data to achieve high frame rates. The single-thread performance is strong, as indicated by a 3DMark single-thread score of 1016 and a Passmark single-thread score of 3925. This is beneficial for Roblox, which often relies on a few primary threads for its engine. The CPU’s 84th percentile ranking among all CPUs, with an average benchmark score of 27827, shows it is a high-end part. Its nearest rival, the Intel Core i9-10900K, has a nearly identical score, indicating parity in overall throughput.

At higher resolutions, the CPU’s workload does not increase as much as the GPU’s, so the frame rate drops are primarily attributable to the graphics card. The CPU’s performance is more than sufficient to avoid becoming the bottleneck, even at 4K, where the average FPS is limited by the RX 580. The data indicates that the CPU is not the limiting component in this combo; instead, it provides a strong foundation that allows the GPU to perform to its full potential, which is constrained by its own architecture and memory bandwidth. The 10 cores and 16 threads ensure that background tasks and game threads are handled without issue, but the overall frame rate is dictated by the GPU’s ability to render frames.
