Roblox

Roblox is a uniquely demanding title for high-refresh-rate hardware because its CPU-bound nature can shift the bottleneck in unexpected ways. The pairing of the Intel Core i7-14700KF with the NVIDIA GeForce RTX 4070 SUPER produces a dataset that clearly illustrates where the limits lie, particularly when dialing through the available presets. The measured frames per second across three resolutions reveal a component relationship that is more nuanced than a simple GPU upgrade path.

Resolution Scaling

The FPS deltas between 1080p, 1440p, and 4K provide a clear picture of the workload distribution. At 1920x1080 with Low settings, the combo produces 560 FPS. Moving to 2560x1440 Low drops this to 374 FPS, a reduction of 186 FPS. The 4K Low result of 211 FPS is another 163 FPS lower. This scaling pattern shows that even at the lowest graphical preset, the rendering load increases substantially with pixel count, but the absolute numbers remain high enough to suggest that the CPU is still feeding frames efficiently.

The High preset tells a more telling story. At 1080p High, the system hits 450 FPS. At 1440p High, it falls to 300 FPS, which is exactly a 33% reduction. The 4K High result of 170 FPS is a 43% drop from the 1440p figure. This steeper percentage decline at higher resolutions indicates that the RTX 4070 SUPER is becoming the primary limiting factor as the pixel shader workload grows. The GPU’s 12 GB GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth is being tasked more heavily, and the data shows the consequences.

The Medium preset offers the only complete frame time data, with min and max values recorded. At 1080p Medium, the average is 509 FPS with a minimum of 433 FPS and a maximum of 586 FPS. The spread of 153 FPS between min and max suggests some volatility, likely from CPU scheduling or scene complexity. At 1440p Medium, the average drops to 340 FPS, with a min of 289 and a max of 391. The frame pacing tightens slightly relative to the average. At 4K Medium, the average is 192 FPS, with a min of 163 and a max of 221. The ratio of min-to-average improves as resolution increases, which is a classic sign of the GPU becoming the consistent bottleneck, smoothing out CPU-induced hitches.

Ultra settings provide the most demanding scenario. The 1080p Ultra result of 365 FPS is 195 FPS lower than the 1080p Low result. At 1440p Ultra, the average is 244 FPS, and at 4K Ultra, it falls to 138 FPS. The delta between 1440p and 4K on Ultra is 106 FPS, which is a 43% reduction. This matches the High preset’s scaling between those resolutions, confirming that the GPU is the dominant constraint above 1440p when graphical complexity is high. The data indicates that the i7-14700KF has enough headroom to push beyond 170 FPS at 4K High, but the graphics card cannot keep up with the pixel throughput demands.

How This Combo Ranks

Within the benchmark database, this specific pairing achieves a rank of 651 out of 3711 tested combinations for Roblox. This places it in the top 17.5% of all configurations evaluated for this game. The percentile ranking is notable because Roblox is often considered a lightweight title, yet the sheer number of combinations tested (3711) means that even a top-quartile finish requires substantial hardware capability.

The ranking reflects the balanced nature of this setup. The CPU’s high multi-threaded performance, evidenced by a Cinebench R23 multi-core score of 44167 and a Geekbench multi-core score of 21462, ensures that the game’s simulation and physics threads are never starved. The GPU’s Passmark G3D score of 29995 provides the rasterization horsepower needed to maintain high frame rates at demanding resolutions. The combo’s position at 651 suggests it outperforms many rigs with newer or more expensive GPUs that are paired with weaker processors, as Roblox’s frame generation often depends on the CPU’s single-thread efficiency.

The nearest rival data for the CPU shows it is tightly clustered with other high-end processors. The Intel Core i7-14700KF has an average benchmark score of 70163, which is 0.2% higher than the AMD Ryzen 7 9700F (69996) and 0.9% higher than the AMD Ryzen 9 7950X (69515). It trails the Intel Core Ultra 7 265K (70879) by 1%. This proximity means that swapping the CPU for any of these alternatives would likely produce negligible differences in Roblox, reinforcing that the combo’s rank is more dependent on the GPU and overall system balance. The RTX 4070 SUPER’s average benchmark score of 43223 places it just 0.1% behind the NVIDIA Quadro M6000 24 GB (43262) and 1% behind the NVIDIA GeForce RTX 4090 Mobile (43667).

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is built on the Ada Lovelace architecture with a 5 nm process node. Its 12 GB of GDDR6X memory operates at 1313 MHz, delivering 504.2 GB/s of bandwidth across a 192-bit bus. The core clocks are listed with a base of 1980 MHz and a boost of 2475 MHz. These specifications translate into a Passmark G3D score of 29995, which places the GPU in the 83rd percentile of all graphics cards.

In the context of Roblox’s measured performance, the GPU’s role becomes more pronounced as resolution increases. At 1080p, the average FPS across all settings ranges from 365 (Ultra) to 560 (Low). The difference of 195 FPS between Low and Ultra at 1080p is substantial, but the absolute numbers are high enough that the GPU is not the sole arbiter. The 4K results tell a different story. The jump from Low (211 FPS) to Ultra (138 FPS) is only 73 FPS, a much smaller absolute delta. This compression of performance at 4K indicates that the GPU’s shading units and memory bandwidth are being saturated.

The transistor count of 35,800 million and the die size of 294 mm² provide the physical resources for 7168 shading units and 80 ROPs. The pixel rate of 198.0 GPixel/s and texture rate of 554.4 GTexel/s are the raw throughput figures that govern how quickly the GPU can fill the screen. At 4K Ultra, the average of 138 FPS suggests that the GPU is hitting a wall where additional graphical features consume the available bandwidth. The DirectX 12 Passmark score of 110 is relatively low compared to the DirectX 11 score of 273, but Roblox’s rendering engine likely does not leverage the full API feature set.

Measured FPS Breakdown

The complete dataset for Roblox with the Intel Core i7-14700KF and NVIDIA GeForce RTX 4070 SUPER is as follows:

At 3840x2160, the average FPS scales from 138 on Ultra to 211 on Low. The High preset averages 170 FPS, while Medium averages 192 FPS with a minimum of 163 and a maximum of 221. The progression is linear, with each step down in settings providing a roughly 20-40 FPS increase.

At 2560x1440, the averages are 244 (Ultra), 300 (High), 340 (Medium), and 374 (Low). The Medium preset again provides the only min/max data, with 289 minimum and 391 maximum. The delta between Low and Ultra is 130 FPS, which is a 35% reduction from Low to Ultra.

At 1920x1080, the averages are 365 (Ultra), 450 (High), 509 (Medium), and 560 (Low). The Medium preset has a minimum of 433 and a maximum of 586. The gap between Low and Ultra is 195 FPS, the largest absolute spread across all resolutions.

A notable observation is the consistency of the Medium preset’s min-to-max range. At 1080p, the range is 153 FPS (433 to 586). At 1440p, it is 102 FPS (289 to 391). At 4K, it is 58 FPS (163 to 221). This narrowing range with increasing resolution is a hallmark of the GPU becoming the limiting factor, as the variance in CPU-side frame generation is smoothed over by the longer GPU render times.

CPU Role

The Intel Core i7-14700KF has 20 cores and 28 threads, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It features 33 MB of shared L3 cache and operates on the Intel Socket 1700 platform. Its Cinebench R23 multi-core score is 44167, and its single-core score is 6235. The Passmark single-thread score is 4480, which is a critical metric for Roblox’s primary thread.

In Roblox, the CPU’s role is to manage the game’s physics simulation, script execution, and network synchronization. The high single-thread performance, as evidenced by the Geekbench single-core score of 2578, ensures that the main game thread does not become a bottleneck even at 1080p Low where the system reaches 560 FPS. The multi-threading capability, with a Passmark multithread score of 52425, handles background tasks and asset streaming without interfering with frame pacing.

The CPU’s percentile ranking of 94th out of all CPUs indicates it is in the top 6% of processors by average benchmark score. Its performance relative to rivals is exceptionally tight, with a 0.2% delta from the AMD Ryzen 7 9700F and a 1% deficit to the Intel Core Ultra 7 265K. This minimal variance suggests that the CPU’s architectural efficiency, rather than raw core count, is what enables the high frame rates seen in the 1080p tests. The 125 W TDP and unlocked multiplier allow for sustained boost clocks, which is beneficial for Roblox’s bursty workload patterns.

Settings Recommendations

Based on the measured rows, the optimal settings depend on the target refresh rate and resolution. For 4K displays, the High preset at 170 FPS is the most balanced choice, as stepping down to Medium (192 FPS) only yields a 22 FPS improvement, while the visual quality reduction may not be worth the modest gain. The Ultra preset at 138 FPS is still playable, but the High preset provides a more comfortable margin above 144 Hz refresh rates.

For 1440p displays, the Medium preset at 340 FPS is the recommended starting point. It provides a substantial improvement over High (300 FPS) and maintains a minimum of 289 FPS, which is above most high-refresh displays. The Ultra preset at 244 FPS is also viable, but the 96 FPS difference between Low (374 FPS) and Ultra (244 FPS) suggests that the graphical enhancements come at a significant performance cost. The Medium preset offers the best balance of visual fidelity and frame rate stability, as evidenced by its min/max range.

For 1080p displays, the data shows that even Ultra settings (365 FPS) far exceed the 240 Hz refresh rate of most monitors. The Medium preset at 509 FPS is the highest setting that still provides a min FPS above 400 (433). The High preset at 450 FPS is a safe choice for consistent performance, but the extra 59 FPS from Medium may be worth it if the visual difference is negligible. The Low preset at 560 FPS offers no practical benefit over Medium unless the user is chasing absolute maximum frame rates for competitive play.

The Medium preset across all resolutions shows the most consistent frame pacing, with the min FPS at 4K (163) being above 144 Hz. This suggests that Medium is the most stable preset for this combo, providing a smooth experience regardless of resolution. The Ultra preset, while visually superior, introduces more frame time variance, particularly at 1080p where the 365 FPS average is not accompanied by min/max data, implying less certainty in the frame delivery.
