Roblox

Roblox with an Intel Core i5-12400 and NVIDIA GeForce RTX 2060 SUPER is a pairing that produces remarkably high frame rates, but the scaling pattern across resolutions reveals a system that transitions from a CPU-limited state at 1080p to a GPU-limited state at 4K. The data shows a clear hierarchy where the performance ceiling drops significantly as pixel count rises, yet even the most demanding settings remain highly playable.

Resolution Scaling

The measured FPS data shows a steep performance gradient as resolution increases from 1920x1080 to 3840x2160. At 1080p with Low settings, the system achieves 308.4 FPS, but this drops to 206.6 FPS at 1440p and further to 114.8 FPS at 4K. This represents a 62.8% reduction in frame rate from 1080p Low to 4K Low, indicating that the GPU is increasingly becoming the limiting factor as resolution climbs.

The scaling behavior changes character at higher settings. With Ultra settings, the frame rate falls from 202.3 FPS at 1080p to 133.5 FPS at 1440p, then plunges to 73.5 FPS at 4K. The 4K Ultra result is dramatically lower than the 1080p Low result, a 76.2% drop, which strongly suggests that the RTX 2060 SUPER's rendering pipeline is saturated at 4K with maximum quality presets. The gap between Low and Ultra settings widens from 106.1 FPS at 1080p to 41.3 FPS at 4K, showing that settings have a proportionally larger impact on performance at higher resolutions.

At 1080p, the frame rates across all settings exceed 200 FPS, which is well beyond the refresh rate of most monitors. This indicates that the Intel Core i5-12400 is the primary bottleneck at this resolution, as the GPU has headroom to render more frames but is constrained by CPU-bound game logic. At 1440p, the system still delivers over 130 FPS at Ultra, maintaining a smooth experience. The 4K results, while lower, remain playable, with the Low preset hitting 114.8 FPS and Medium achieving 108.5 FPS.

The transition from 1440p to 4K shows the most significant per-resolution performance hit. At High settings, the drop from 167.7 FPS to 94.7 FPS represents a 43.5% reduction, which is the largest relative decline between adjacent resolutions. This pattern confirms that the RTX 2060 SUPER's 8 GB GDDR6 memory and 256-bit bus are adequate for 1440p but become strained at 4K, where the increased pixel throughput demands more from the GPU's shading units and texture mapping units.

GPU Role

The NVIDIA GeForce RTX 2060 SUPER, built on the Turing architecture with the TU106 chip, plays a decisive role in determining the upper limits of performance at higher resolutions. Its 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which is sufficient for Roblox's texture-heavy environments at 1440p but shows limitations at 4K Ultra. The GPU's boost clock of 1650 MHz and base clock of 1470 MHz are modest by modern standards, yet the benchmark results demonstrate that this configuration handles Roblox with ease.

The GPU's compute capabilities include 2176 shading units, 136 texture mapping units, and 64 raster operation pipelines, delivering 7.181 TFLOPS of FP32 performance. These specifications translate to a Passmark G3D score of 16462, placing the RTX 2060 SUPER in the 63rd percentile of all GPUs. The nearest rival, the NVIDIA GeForce GTX TITAN, scores 19706, which is a 0.3% delta from the RTX 2060 SUPER's average benchmark score of 19774. This close margin indicates that the RTX 2060 SUPER performs comparably to much older flagship hardware in synthetic tests.

The GPU's ray tracing cores, numbering 34, and tensor cores, numbering 272, are present but largely irrelevant for Roblox, which is a sandbox game that does not utilize these features in its standard rendering path. The memory clock of 1750 MHz, operating at 14 Gbps effective, provides sufficient bandwidth for the game's asset streaming. The 4K Ultra result of 73.5 FPS suggests that the GPU's pixel rate of 105.6 GPixel/s is the limiting factor at this resolution, as the rendering pipeline becomes saturated with fill-rate demands.

The RTX 2060 SUPER's DirectX 12 Ultimate support and Vulkan 1.4 compatibility ensure that it can handle modern graphics APIs, but Roblox's engine is primarily DirectX 11-based. The Passmark DirectX 11 score of 130 is notably higher than the DirectX 12 score of 61, which aligns with the game's rendering approach. This means the GPU operates in its most efficient mode when running Roblox, explaining the high frame rates observed even at 4K.

CPU Role

The Intel Core i5-12400, a 6-core, 12-thread processor from the Alder Lake-S architecture, provides the computational foundation for this system. With a base clock of 2.50 GHz and a boost clock of 4.40 GHz, this CPU delivers strong single-threaded performance that is critical for Roblox's physics and game logic. The processor's 18 MB of shared L3 cache and 1.25 MB per-core L2 cache help reduce memory latency, which is beneficial for the game's frequent object interactions.

The CPU's benchmark results show a clear strength in multi-threaded workloads, with a Cinebench R23 multicore score of 15935 and a Passmark multithread score of 18747. The single-thread performance is equally impressive, with a Cinebench R23 single-core score of 2249 and a Passmark single-thread score of 3456. These scores place the i5-12400 in the 77th percentile of all CPUs, with an average benchmark score of 19850. The nearest rival, the Intel Core i7-9700, scores 19831, a mere 0.1% delta, indicating that the i5-12400 matches a previous-generation i7 in overall performance.

The CPU's role in Roblox becomes evident when examining the 1080p results. At Low settings, the system produces 308.4 FPS, but this figure is likely constrained by the CPU's ability to process game state updates rather than the GPU's rendering capacity. The 3DMark single-thread score of 910 and 2-thread score of 1692 suggest that the CPU has sufficient headroom for most gaming scenarios, but Roblox's engine can be demanding on a single core for physics calculations.

The i5-12400's 12 threads allow for efficient multitasking and background processing, which is beneficial for maintaining consistent frame times. The CPU's TDP of 65 W and support for DDR4 and DDR5 memory provide flexibility for system builders, though the measured performance is what matters for this analysis. The 3DMark max threads score of 5890 and 16-thread score of 5873 show that the CPU scales well with additional threads, though Roblox is unlikely to utilize all 12 threads simultaneously.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across resolutions and settings. At 1920x1080, the system delivers exceptional frame rates across all presets: 308.4 FPS at Low, 278.2 FPS at Medium, 244.9 FPS at High, and 202.3 FPS at Ultra. These results indicate that the CPU is the primary bottleneck at this resolution, as the GPU has ample headroom to render more frames if the CPU could feed it faster.

Moving to 2560x1440, the frame rates remain high but show the GPU beginning to assert its influence. The results are 206.6 FPS at Low, 188.1 FPS at Medium, 167.7 FPS at High, and 133.5 FPS at Ultra. The drop from 1080p to 1440p ranges from 33% at Low to 34% at Ultra, showing a consistent scaling pattern that is characteristic of a balanced CPU-GPU pairing where the GPU becomes more involved.

At 3840x2160, the GPU's limitations become apparent. The results are 114.8 FPS at Low, 108.5 FPS at Medium, 94.7 FPS at High, and 73.5 FPS at Ultra. The 4K Ultra result is particularly notable as it represents the lowest measured performance, but it still exceeds 60 FPS, making it playable on most displays. The gap between Low and Ultra at 4K is 41.3 FPS, which is smaller than the 106.1 FPS gap at 1080p, confirming that the GPU is the limiting factor at higher resolutions.

The data shows that the system is best suited for 1080p and 1440p gaming, where it delivers well over 130 FPS at all settings. At 4K, the system remains capable but requires setting adjustments to maintain high frame rates. The Low preset at 4K achieves 114.8 FPS, making it the recommended choice for competitive play, while the Ultra preset at 73.5 FPS is suitable for visually rich experiences on slower displays.
