Roblox

The Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 5070 delivers extraordinary frame rates in Roblox, a sandbox title that scales predictably with resolution but remains heavily CPU-bound at lower settings. The data shows a clear progression: at 1080p Low, the combo produces 542.5 FPS, dropping to 436.2 FPS at High, 491 FPS at Medium, and 355.3 FPS at Ultra. Moving to 1440p, the average FPS falls to 365.2 at Low, 332.1 at Medium, 290.6 at High, and 236.7 at Ultra. At 4K, the numbers compress further: 205 FPS at Low, 184.8 at Medium, 164.9 at High, and 133.3 at Ultra. The scaling pattern reveals that the RTX 5070 is not the limiting factor at 1080p; the drop from Low to Ultra at 1080p is only about 34% (from 542.5 to 355.3 FPS), whereas the jump from 1080p Low to 4K Low is a 62% reduction (from 542.5 to 205 FPS). This indicates that at high resolutions and higher settings, the GPU workload dominates, but at 1080p the CPU's 20 cores and 28 threads are likely the bottleneck, as the frame rates exceed what most displays can even refresh.

Resolution Scaling

The performance trajectory across resolutions in Roblox is steep but consistent. At 1920x1080 with Low settings, the combo hits 542.5 FPS, which is the peak observed in this dataset. Raising the settings to Medium reduces the average to 491 FPS, a 9.5% drop, while High yields 436.2 FPS (a further 11% decline) and Ultra bottoms out at 355.3 FPS. This pattern suggests that at 1080p, the CPU's strong single-thread performance — evidenced by its 6290 score in Cinebench R23 single-core — is sufficient to feed the GPU, and the variance comes from increased shading and texture work.

At 2560x1440, the same settings ladder shows a more pronounced GPU influence. Low produces 365.2 FPS, Medium 332.1 FPS, High 290.6 FPS, and Ultra 236.7 FPS. The delta between Low and Ultra at 1440p is 35%, which is steeper than at 1080p (34% drop from 542.5 to 355.3), but the absolute numbers remain extremely high. The shift to 3840x2160 reveals the RTX 5070's 12 GB of GDDR7 memory and 672.0 GB/s bandwidth starting to matter more: Low yields 205 FPS, Medium 184.8 FPS, High 164.9 FPS, and Ultra 133.3 FPS. The drop from 1440p Low to 4K Low is 44%, indicating that the GPU is now the primary constraint. Notably, the gap between 1080p Ultra (355.3 FPS) and 4K Ultra (133.3 FPS) is a 62% reduction, confirming that Roblox's visual effects at Ultra settings scale heavily with resolution, taxing the 30.87 TFLOPS FP32 compute of the RTX 5070.

The limiting component shifts based on resolution. Below 1440p, the i7-14700KF's boost clock of 5.60 GHz and its 33 MB of shared L3 cache are sufficient to push frame rates past 400 FPS, meaning the GPU is underutilized. At 4K, the RTX 5070's pixel rate of 201.0 GPixel/s and 80 ROPs become the deciding factors, as the average FPS drops below 200 even at Low settings. This hybrid behavior is typical for a sandbox game like Roblox, which has simple geometry but can be demanding on draw calls, making the CPU's 20 cores (with 8 performance and 12 efficient) critical at lower resolutions.

How This Combo Ranks

In the broader database of tested combinations, this pairing of the Core i7-14700KF and RTX 5070 ranks 372 out of 1800 combos for Roblox. This places it in the top 21% of all tested systems, which is a strong showing given the game's reputation for being modestly demanding. The ranking reflects the combo's ability to maintain high frame rates across all settings, but it is not the absolute top tier, likely because Roblox is not a AAA title that stresses the GPU to its limits. The percentileVsAllCpus for the i7-14700KF is 96, meaning it outperforms 96% of all CPUs in the database, while the RTX 5070 has a percentileVsAllGpus of 83. The CPU's high percentile contributes more to the combo's ranking than the GPU's, since Roblox's physics and world simulation depend on processor performance.

Compared to the nearest rivals in the CPU benchmark aggregate, the i7-14700KF averages 70104 points, which is essentially tied with the Intel Core i7-14700K (70074 points, 0% delta) and the AMD Ryzen 9 9950X (70420 points, -0.4% delta). The AMD EPYC 9115 trails by 0.3% (69887 points), and the Intel Xeon Platinum 8270 is 1.3% ahead (71056 points). These deltas are minuscule, suggesting that the i7-14700KF's performance in Roblox is not uniquely superior but is competitive with other high-end processors. For the GPU, the RTX 5070's avgBenchmarkScore is 41687, with the AMD Radeon Pro 5300 at 41610 (0.2% ahead), the NVIDIA Tesla M40 at 41897 (0.5% ahead), the RTX 3090 at 41441 (0.6% behind), and the AMD Radeon Pro 580X at 41991 (0.7% ahead). These rival deltas are all within 1%, meaning the RTX 5070's position is tightly clustered, and the combo's rank is more influenced by the CPU's dominance than the GPU's raw score.

GPU Role

The NVIDIA GeForce RTX 5070 is a Blackwell 2.0 architecture part built on a 5 nm process at TSMC, with 31,100 million transistors on a 263 mm² die. Its base clock is 2325 MHz and boost clock is 2512 MHz, which are modest compared to some rivals but sufficient for Roblox's requirements. The memory subsystem is notable: 12 GB of GDDR7 on a 192-bit bus yields 672.0 GB/s of bandwidth, and the memory clock runs at 1750 MHz (28 Gbps effective). This bandwidth is critical at 4K Ultra, where the game's textures and effects require more data movement; the data shows 133.3 FPS at that setting, still very playable but lower than the 236.7 FPS at 1440p Ultra.

The GPU's shading units total 6144, with 192 TMUs and 80 ROPs, and it offers 48 RT cores and 192 tensor cores. The FP32 throughput is 30.87 TFLOPS, which is ample for Roblox's simple shaders. The pixel rate of 201.0 GPixel/s and texture rate of 482.3 GTexel/s are what drive the resolution scaling observed. At 1080p, the GPU is often idle waiting for the CPU, as evidenced by the small frame rate gap between Low (542.5 FPS) and High (436.2 FPS) — a 106 FPS difference that is more likely due to CPU-side draw call limits than GPU fill rate. At 4K, the GPU's compute and memory bandwidth become the bottleneck, with the frame rate dropping by half from 1080p High (436.2 FPS) to 4K High (164.9 FPS). The RTX 5070's 250 W TDP and dual-slot design suggest it is a mainstream performer, and its PassMark G3D score of 29137 places it in the 83rd percentile of all GPUs, confirming it is a solid mid-range choice for this title.

CPU Role

The Intel Core i7-14700KF is a Raptor Lake-R architecture processor on a 10 nm process, featuring 20 cores (8 performance cores and 12 efficient cores) and 28 threads. Its base clock is 3.40 GHz and boost clock is 5.60 GHz, with a 125 W TDP. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. This configuration excels in Roblox because the game's physics and world simulation benefit from high single-thread performance; the Cinebench R23 single-core score of 6290 is robust, and the PassMark single-thread score of 4480 confirms this strength.

The CPU's multi-threaded capabilities are also relevant, as Roblox can utilize multiple cores for server-side simulation or complex user-generated content. The Cinebench R23 multi-core score of 44557 and Geekbench multi-core score of 19287 indicate that the i7-14700KF can handle any background tasks without impacting frame rates. In the measured data, the 1080p Low result of 542.5 FPS is likely limited by the CPU's ability to process game logic and issue draw calls, given that the GPU is far from saturated at that resolution. The fact that the 1440p Low result (365.2 FPS) is lower than 1080p Low suggests the GPU is beginning to take over, but the CPU still has headroom.

The i7-14700KF's nearest rivals in the aggregate CPU benchmark are all within 1.3% of its average score of 70104, meaning the choice of processor among these top-tier chips has minimal impact on Roblox performance. The AMD Ryzen 9 9950X is 0.4% ahead, while the Intel Core i7-14700K is exactly tied. This close grouping indicates that Roblox is not highly sensitive to CPU architecture differences once a certain performance threshold is met. The CPU's 96th percentile ranking versus all CPUs, combined with its 20 cores and 28 threads, ensures that it will not be the bottleneck in most scenarios, leaving the RTX 5070 to handle the graphical load. At 4K Ultra, the CPU's role diminishes further, as the frame rate of 133.3 FPS is well within the CPU's capabilities, allowing the GPU to be the sole constraint.
