# Roblox with Intel Core i5-14600KF + NVIDIA GeForce RTX 3070 Ti

The combination of the Intel Core i5-14600KF and NVIDIA GeForce RTX 3070 Ti produces exceptionally high frame rates in Roblox, with measured averages ranging from 109.3 FPS at 4K Ultra to 436 FPS at 1080p Low. This places the combo at rank 703 out of 1800 tested configurations, indicating strong but not top-tier performance in this sandbox title. The data reveals a system that is heavily GPU-limited at higher resolutions but capable of saturating high-refresh displays at 1080p and 1440p across all settings.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor from the Raptor Lake Refresh generation, built on Intel's 10 nm process. It operates with a base clock of 3.50 GHz and a boost clock of 5.30 GHz, supported by a 24 MB shared L3 cache and 2 MB L2 cache per core. Its benchmark profile shows strong multi-threaded capabilities: a Cinebench R23 multi-core score of 32889 and a single-core score of 4643, alongside a Geekbench multi-core score of 15636 and single-core score of 2778. The PassMark multithread score of 38697 and single-thread score of 4273 further confirm balanced performance.

In Roblox, which is largely a single-thread-bound sandbox engine, the i5-14600KF's single-core strength matters most. The data shows that at 1080p Low, the system achieves 436 FPS, and at 1080p Medium it reaches 394 FPS — both figures suggest the CPU is delivering frames that far exceed typical display refresh rates. The processor's 5.30 GHz boost clock and 24 MB L3 cache provide the headroom needed for Roblox's physics and scripting workloads. However, the CPU's role becomes less dominant as resolution increases; the frame rate deltas between settings at 4K are smaller in absolute terms, indicating that the GPU takes over as the primary limiter.

The i5-14600KF's percentile rank of 93 among all CPUs, with an average benchmark score of 49367, places it within 0.4% of the Intel Core i5-14600K (avg score 49166) and 0.6% ahead of the AMD Ryzen 9 5950X (avg score 49062). This proximity to the 14600K suggests the unlocked multiplier (enabling overclocking) is the primary differentiator, not raw architecture. For Roblox, where frame pacing is often inconsistent, the CPU's high single-thread throughput ensures that the game logic does not bottleneck the rendering pipeline — a critical factor given that even at 4K Ultra, the system maintains 109.3 FPS.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture using Samsung's 8 nm process, with a GA104 chip containing 17,400 million transistors across a 392 mm² die. It features 6144 shading units, 192 texture mapping units, and 96 raster output units, paired with 8 GB of GDDR6X memory on a 256-bit bus. The memory operates at 19 Gbps effective, delivering a bandwidth of 608.3 GB/s. Clock speeds are rated at 1575 MHz base and 1770 MHz boost, while the GPU's FP32 performance reaches 21.75 TFLOPS.

In Roblox, the GPU's role scales with both resolution and settings. At 1080p, the RTX 3070 Ti delivers 352.3 FPS on High and 286.1 FPS on Ultra — figures that suggest the GPU is not breaking a sweat, as the CPU is likely the limiting factor at these lower resolutions. Moving to 1440p, the frame rates remain high: 236.6 FPS on High and 190.9 FPS on Ultra. At 4K, the GPU's workload increases substantially, with High settings producing 132.6 FPS and Ultra dropping to 109.3 FPS. The 8 GB VRAM capacity and 608.3 GB/s bandwidth are sufficient for Roblox's relatively modest texture and geometry demands, even at 4K Ultra.

The GPU's percentile rank of 74 among all GPUs, with an average benchmark score of 30849, places it in a competitive position. Compared to its nearest rivals, the RTX 3070 Ti sits 0.3% above the AMD Radeon RX 590 GME (avg score 30755) and 0.8% below the AMD Radeon RX 6700 (avg score 31112). This narrow margin in synthetic tests contrasts with the measured Roblox results, where the RTX 3070 Ti's ray tracing and tensor cores (48 and 192, respectively) may not be heavily utilized but its raw rasterization power clearly drives high frame rates. The GPU's PassMark G3D score of 23356 and DirectX 12 score of 91 indicate solid API efficiency, aligning with the observed performance scaling.

Resolution Scaling

The measured FPS data reveals a clear pattern of resolution-dependent scaling. From 1080p to 1440p, the average frame rate drops by approximately 33% across all settings: High goes from 352.3 to 236.6 FPS (a 115.7 FPS reduction), Low from 436 to 288.6 FPS (147.4 FPS reduction), Medium from 394 to 262.5 FPS (131.5 FPS reduction), and Ultra from 286.1 to 190.9 FPS (95.2 FPS reduction). This scaling is consistent with the GPU becoming more stressed as pixel count increases by 77.8% from 1080p to 1440p.

The transition from 1440p to 4K shows even steeper relative drops. High settings fall from 236.6 to 132.6 FPS (a 44% reduction), Low from 288.6 to 165.7 FPS (42.6% reduction), Medium from 262.5 to 149.3 FPS (43.1% reduction), and Ultra from 190.9 to 109.3 FPS (42.7% reduction). The 4K resolution quadruples the pixel count of 1080p, and the frame rate reductions are proportionally larger, confirming that the RTX 3070 Ti is the limiting component at 4K. At 1080p, the fact that Low (436 FPS) is only 23.7% faster than Ultra (286.1 FPS) suggests the CPU prevents the GPU from being fully utilized at lower resolutions.

The data indicates that the system transitions from CPU-bound at 1080p to GPU-bound at 4K. At 1440p, the balance is more even, with frame rates still above 190 FPS even at Ultra. For users targeting high refresh rates, 1440p represents the sweet spot: the GPU maintains over 190 FPS at all settings, while 4K requires dropping to Low (165.7 FPS) or Medium (149.3 FPS) to stay above 144 FPS. The 109.3 FPS at 4K Ultra is still playable but falls below the threshold for high-refresh monitors.
