Roblox

Roblox is a uniquely lightweight title, and pairing it with an Intel Core i7-12700KF and NVIDIA GeForce RTX 4080 produces extraordinary frame rates that are almost entirely CPU-bound at lower resolutions. The benchmark data shows that this combination sits at rank 250 out of 3711 tested combos, placing it in the top 7% of all systems tested for this game. The measured results reveal a system that obliterates standard display refresh rates at every setting, making the choice of preset less about achieving playability and more about optimizing for visual fidelity versus raw, often unnecessary, frame throughput.

Settings Recommendations

The data indicates that the High preset is the optimal choice for most users with this hardware, regardless of resolution. At 1920x1080, High delivers an average of 517 FPS, which is more than sufficient for any high-refresh-rate monitor. Moving to Medium increases the average to 585 FPS, but this 68 FPS gain comes at the cost of visual quality. The Low preset pushes the average to 643 FPS, but the visual degradation is severe enough that the performance benefit is largely wasted, as even the High preset exceeds the refresh rate of all but the most extreme gaming monitors.

At 2560x1440, the High preset maintains an average of 345 FPS, which is still an excellent result for a 1440p monitor. The Ultra preset drops to 280 FPS, which is still above the refresh rate of most high-end 1440p displays (typically 240Hz). The Medium preset offers 390 FPS, a 45 FPS increase over High, but the visual differences between High and Medium in Roblox are typically less pronounced than the performance delta suggests. The Low preset at 1440p (429 FPS) is only 84 FPS faster than High, a marginal improvement in practical terms.

For 4K, the High preset delivers an average of 195 FPS, which is still a superb experience on a 120Hz or 144Hz 4K panel. The Ultra preset drops to 158 FPS, which is still playable but approaches the limit of what a 144Hz display needs. The Medium preset at 221 FPS provides a significant headroom over High, but again, the visual compromise is generally not worth it. The Low preset at 4K (243 FPS) is the only setting where you might consider using it, as it offers a 48 FPS advantage over High, which could be relevant for a 240Hz 4K display, but such panels are rare.

The practical recommendation is to use High for all resolutions. The data shows that this preset provides the best balance between visual quality and performance, with the FPS being high enough to max out any monitor's refresh rate in most scenarios. If you own a 500Hz esports monitor, you can experiment with Low, but for the vast majority of users, the visual improvements of High are more valuable than the extra frames that lower presets provide.

GPU Role

The NVIDIA GeForce RTX 4080 is massively overqualified for this game, yet the data shows it is not the primary bottleneck in most situations. The GPU features a 16 GB GDDR6X memory pool with a 256-bit bus width, offering 716.8 GB/s of bandwidth. This is far more than Roblox requires, so memory capacity and bandwidth are not limiting factors in the measured results. The GPU's core specifications include 9728 shading units, 304 texture mapping units, and 112 raster output units, with boost clocks reaching 2505 MHz.

The GPU's raw compute performance is immense, with an FP32 throughput of 48.74 TFLOPS. In synthetic benchmarks, it scores 34457 in Passmark G3D and 54247 in the overall average benchmark, placing it at the 86th percentile of all GPUs. Its nearest rivals include the RTX 4080 SUPER, which is only 0.1% ahead, and the AMD Radeon RX 6750 GRE 12 GB, which is 2.6% ahead in the aggregate benchmark score. However, these aggregate scores do not directly translate to Roblox performance.

The evidence that the GPU is not the main bottleneck is the scaling pattern. At 1080p High, the system produces 517 FPS. When moving to 1440p High, the FPS drops to 345 FPS, a 33% decrease. When moving to 4K High, the FPS drops to 195 FPS, a 43% decrease from 1440p. If the GPU were the sole bottleneck, the drop from 1080p to 1440p would be much smaller, as the GPU has ample headroom. The fact that the FPS drops significantly when increasing resolution suggests that the GPU is becoming more relevant, but it still produces over 158 FPS at 4K Ultra, indicating that even at its most demanding, the RTX 4080 is not stressed by this title.

Resolution Scaling

The resolution scaling pattern in the data reveals a system that is heavily CPU-limited at lower resolutions, with the GPU becoming the primary limiting factor only at 4K. Starting with the High preset, the frame rates are: 517 FPS at 1080p, 345 FPS at 1440p, and 195 FPS at 4K. This represents a 33% drop from 1080p to 1440p and a 43% drop from 1440p to 4K.

The fact that the 1080p to 1440p drop is so significant indicates that the CPU is still able to feed the GPU at 1080p, and the GPU is being increasingly utilized as the pixel count rises. At 1080p, the CPU is likely the limiting factor, as the FPS is extremely high but not scaling linearly with the GPU's capability. The 1440p result of 345 FPS is still very high, and the CPU is still providing enough data to keep the GPU busy.

At 4K, the GPU becomes the clear bottleneck. The 195 FPS at High is a strong result, but it is only 37% of the 1080p figure. This is a typical scaling pattern for a game like Roblox, which is not graphically intensive. The GPU's rendering load increases significantly at 4K, and the RTX 4080, while powerful, cannot maintain the same frame rates as at 1080p. The Low preset scaling is similar: 643 FPS at 1080p, 429 FPS at 1440p, and 243 FPS at 4K. This suggests that even at the lowest settings, the GPU is still the primary limiter at 4K, as the FPS is not hitting the CPU's maximum potential.

CPU Role

The Intel Core i7-12700KF plays a critical role in this game's performance, particularly at lower resolutions where the frame rates are extremely high. This CPU has 12 cores and 20 threads, based on the Alder Lake architecture. Its base clock is 3.60 GHz, and it can boost up to 5.00 GHz. This high boost clock is essential for the single-threaded nature of Roblox's game engine. The CPU's cache structure includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3 cache, which helps reduce memory latency.

In synthetic benchmarks, the i7-12700KF shows its strength. It scores 28838 in Cinebench R23 multicore and 4071 in single-core. In 3DMark, it scores 1043 in single-thread and 2065 in 2-threads, which are good indicators of its gaming capability. The multi-thread score of 9983 in 3DMark's max-threads test is less relevant for Roblox but indicates the CPU is not the bottleneck in more demanding titles. The CPU's average benchmark score is 35365, placing it at the 85th percentile of all CPUs. Its nearest rival is the Intel Core i-13700T, which is only 0.1% slower, and the Intel Core i5-13600T, which is 0.2% faster.

The 1080p performance is a direct reflection of the CPU's power. At 1080p High, the system achieves 517 FPS, which is likely at or near the CPU's limit for this game. The fact that the Low preset at 1080p produces 643 FPS indicates that the CPU can handle a very high game logic and draw call rate. The CPU is the primary driver of the high FPS at 1080p, and the GPU has significant headroom. The 4K results are where the CPU becomes less of a bottleneck, as the GPU is the main limiter. However, the CPU still needs to be fast enough to feed the GPU, and the i7-12700KF does this easily, maintaining 158 FPS at 4K Ultra.

Measured FPS Breakdown

At 1920x1080, the data shows the following average frame rates: the Low preset reaches 643 FPS, the Medium preset averages 585 FPS with a minimum of 497 FPS and a maximum of 673 FPS, the High preset averages 517 FPS, and the Ultra preset averages 420 FPS. This is a clear hierarchy, with Low being 23% faster than Medium and High being 23% faster than Ultra. The Medium preset's minimum FPS of 497 is still higher than the High preset's average, indicating that the CPU is not causing stutters at this resolution.

At 2560x1440, the performance scales down predictably. The Low preset averages 429 FPS, Medium averages 390 FPS with a minimum of 332 FPS and a maximum of 449 FPS, High averages 345 FPS, and Ultra averages 280 FPS. The gap between Low and Medium is 39 FPS, while the gap between High and Ultra is 65 FPS. The Medium preset's minimum of 332 FPS is still very high, ensuring a smooth experience.

At 3840x2160, the GPU becomes the main factor. The Low preset averages 243 FPS, Medium averages 221 FPS with a minimum of 188 FPS and a maximum of 254 FPS, High averages 195 FPS, and Ultra averages 158 FPS. The Medium preset's minimum FPS of 188 is close to the High preset's average of 195, which is interesting. The Ultra preset's 158 FPS is still above the 144Hz refresh rate, making it a viable option for 4K gaming. The overall data indicates that this system is overkill for Roblox at any resolution, and the High preset at 1440p (345 FPS) or 4K (195 FPS) is the best choice for a balanced experience.
