GPU Role

The NVIDIA GeForce GTX 1660 SUPER is built on the Turing architecture using a 12nm process from TSMC, featuring 1408 shading units, 88 texture mapping units, and 48 raster operation units. Its memory subsystem consists of 6 GB of GDDR6 memory on a 192-bit bus, delivering 336.0 GB/s of bandwidth. The GPU operates at a base clock of 1530 MHz with a boost clock of 1785 MHz, and memory runs at 1750 MHz (14 Gbps effective). These specifications place the card at the 55th percentile of all GPUs in the benchmark database, with an average benchmark score of 14286.

In Roblox, the GPU's role becomes increasingly evident as resolution and settings scale upward. At 1080p Low settings, the system achieves 236.7 FPS, but at 4K Ultra this drops to 56.6 FPS — a reduction of 180.1 FPS that clearly demonstrates the GPU becoming the limiting factor at higher resolutions. The pixel rate of 85.68 GPixel/s and texture rate of 157.1 GTexel/s are put under increasing strain as the engine renders more pixels at 4K. The GPU's 5.027 TFLOPS of FP32 compute performance is sufficient to handle Roblox's sandbox rendering requirements, but the transition from 1080p to 4K represents a nearly 4x increase in pixel count that the GTX 1660 SUPER must process.

Resolution Scaling

The measured FPS data reveals a clear and consistent pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At High settings, the average FPS drops from 188.3 at 1080p to 127.6 at 1440p, then further to 69.9 at 4K. This represents a 32.2% reduction from 1080p to 1440p, and a 62.9% reduction from 1080p to 4K. The scaling pattern indicates that the GTX 1660 SUPER is the dominant limiting component, as the frame rate drop is roughly proportional to the increase in pixel count.

Low settings show a similar trend: 236.7 FPS at 1080p, 156.1 FPS at 1440p, and 92.2 FPS at 4K. The percentage drops of 34.1% and 61.0% respectively are nearly identical to the High settings scaling, which strongly suggests that the GPU's rendering throughput is the bottleneck rather than CPU or memory constraints. Even at the lowest settings, the 4K resolution imposes a substantial load that the GPU cannot fully compensate for through reduced shading work. Interestingly, the gap between 1080p and 1440p is proportionally similar to the gap between 1440p and 4K, indicating a linear scaling behavior typical of pixel-bound workloads.

Settings Recommendations

For players prioritizing smooth gameplay at 1080p, Ultra settings at 153.3 FPS offer the best experience as the frame rate remains far above any competitive threshold while delivering maximum visual quality. The drop from Medium (218 FPS) to Ultra (153.3 FPS) is significant but still leaves ample performance headroom. At 1440p, Ultra settings at 105.7 FPS remain highly playable, and the visual benefits of max settings are worth the 37.5 FPS reduction from Medium's 143.2 FPS. Players with high-refresh-rate 1440p monitors may prefer Medium settings to stay closer to 144 FPS, but Ultra is a viable choice.

At 4K resolution, the recommendation shifts toward High or Medium settings. Ultra at 56.6 FPS dips below the 60 FPS threshold and may introduce perceptible stuttering on standard 60 Hz displays. High settings at 69.9 FPS provide a comfortable margin above 60 FPS, while Medium at 78.4 FPS offers even more headroom. Low settings at 4K produce 92.2 FPS but sacrifice too much visual fidelity for the modest gain over Medium. The optimal 4K preset is High, which balances visual quality with a frame rate that comfortably exceeds display refresh rates.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake architecture, built on Intel's 10nm process with a die size of 163 mm². It operates at a base clock of 2.50 GHz and boosts up to 4.40 GHz, with a 65W TDP. The CPU features 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 18 MB of shared L3 cache. Memory support includes both DDR4 and DDR5 in dual-channel configuration, with PCIe Gen 5 providing 16 CPU lanes.

Benchmark data shows the i5-12400 achieves a Cinebench R23 multicore score of 15935 and a single-core score of 2249, while 3DMark scores range from 910 (single-thread) to 5890 (max threads). The Passmark multithread score of 18747 and single-thread score of 3456 further characterize its performance profile. The CPU's average benchmark score of 19850 places it at the 77th percentile of all CPUs, with nearest rivals including the Core i7-9700 (0.1% higher) and Core i7-8700 (0.2% higher).

In Roblox, the CPU's role appears secondary to the GPU based on the resolution scaling analysis. The consistent frame rate drops across resolutions indicate the GPU is the primary bottleneck, and the CPU's strong single-thread performance (910 in 3DMark single-thread, 2249 in Cinebench R23 single-core) ensures that Roblox's game logic and physics simulation are handled without becoming a limiting factor. The 6-core, 12-thread configuration provides ample parallelism for any background tasks, and the 18 MB of L3 cache helps maintain low latency for frequently accessed game data. Given that the system achieves 236.7 FPS at 1080p Low settings, the CPU clearly has sufficient headroom to feed the GPU at high frame rates, and even at 4K Ultra the CPU does not appear to constrain performance.
