Roblox

Roblox, a sandbox title released in 2006, presents an unusual benchmark scenario for the Intel Core i7-14700K paired with the AMD Radeon RX 6650 XT. The measured FPS data spans three resolutions and four settings presets, offering a clear view of how this combination scales under load. The i7-14700K, a 20-core Raptor Lake Refresh part, and the RX 6650 XT, an RDNA 2 GPU with 8 GB of GDDR6, produce results that range from 320.8 FPS at 1080p Low to 81.1 FPS at 4K Ultra.

Resolution Scaling

At 1080p High, the combo delivers 259 FPS. Moving to 1440p High drops the average to 170 FPS, and at 4K High it falls to 98.4 FPS. The pattern repeats across all settings presets. Low settings at 1080p produce 320.8 FPS, at 1440p 213.1 FPS, and at 4K 124.1 FPS. Medium settings follow the same curve: 292.8, 193.9, and 111.5 FPS. Ultra settings show 208.8, 139.1, and 81.1 FPS.

The scaling behavior reveals where the bottleneck shifts. The FPS loss from 1080p to 1440p is substantial, and the loss from 1440p to 4K is even larger, pointing to the GPU becoming the limiting component as pixel count rises. At 1080p, the CPU's strong single-thread performance — a Cinebench R23 single-core score of 6287 — keeps frame rates high, but the GPU's 128-bit memory bus and 8 GB VRAM constrain performance as resolution climbs.

The spread between Low and Ultra also changes with resolution. At 1080p, Low reaches 320.8 FPS while Ultra reaches 208.8 FPS. At 4K, Low reaches 124.1 FPS and Ultra 81.1 FPS. The narrowing gap suggests that at 4K, both settings are limited by the same GPU ceiling, whereas at 1080p the CPU can exploit lower settings to push much higher frame rates.

CPU Role

The Intel Core i7-14700K brings 20 cores and 28 threads, with a boost clock of 5.60 GHz and a base clock of 3.40 GHz. Its 33 MB of shared L3 cache and 2 MB per-core L2 cache support high-throughput workloads. In Cinebench R23, the chip scores 44534 multi-core and 6287 single-core. The single-core result is particularly relevant for Roblox, a sandbox game that often relies on a few threads for simulation and rendering logic.

The CPU's benchmark percentile of 96 places it among the top processors tested. Its nearest rivals in the database are tightly clustered: the Intel Core i7-14700KF scores 70104 (a 0% delta), the AMD EPYC 9115 scores 69887 (0.3% higher), the AMD Ryzen 9 9950X scores 70420 (0.5% lower), and the Intel Xeon Platinum 8270 scores 71056 (1.4% lower). This clustering means the i7-14700K is effectively at parity with the fastest CPUs in the database, with the largest delta being 1.4%.

In the measured FPS data, the CPU's influence is most visible at 1080p. The highest recorded average, 320.8 FPS at Low settings, suggests the processor can feed the GPU well beyond typical display refresh rates. Even at 1080p Ultra, the combo maintains 208.8 FPS, indicating that the CPU is not the primary constraint at this resolution. The data implies that Roblox's engine, despite its age, scales with the i7-14700K's single-thread throughput.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2 architecture with the Navi 23 chip. It features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The GPU's boost clock reaches 2635 MHz, with a game clock of 2410 MHz and a base clock of 2055 MHz. Its 2048 shading units, 128 texture mapping units, and 64 ROPs provide a peak FP32 throughput of 10.79 TFLOPS.

The GPU sits at the 72nd percentile of all tested GPUs, with an average benchmark score of 29024. Its nearest rivals are remarkably close: the AMD Radeon RX 6800M scores 29011 (0% delta), the AMD Radeon RX 470 scores 28996 (0.1% higher), the Intel Arc A370M scores 29175 (0.5% lower), and the AMD Radeon RX Vega M GH scores 29197 (0.6% lower). This tight grouping places the RX 6650 XT in a competitive mid-range band.

The GPU's role becomes dominant at 4K. At 4K Ultra, the average FPS falls to 81.1, and even at 4K Low it only reaches 124.1. The 8 GB VRAM and 128-bit bus are likely contributors to this ceiling, as higher resolutions demand more memory bandwidth and capacity. The data shows that the GPU, not the CPU, is the limiting factor at 4K, since the FPS spread between Low and Ultra narrows at that resolution.

Settings Recommendations

The measured rows provide a clear picture of the trade-off between visual quality and frame rate. At 1080p, Medium settings deliver 292.8 FPS, which is higher than High's 259 and Ultra's 208.8. Low settings reach 320.8 FPS, but the jump from Low to Medium costs only a modest FPS reduction while likely improving visual fidelity. Medium is the balanced choice at 1080p.

At 1440p, Medium produces 193.9 FPS, comfortably above High's 170 and Ultra's 139.1. Low at 1440p reaches 213.1 FPS, making Medium a reasonable compromise. At 4K, Medium holds 111.5 FPS, which is above High's 98.4 and well above Ultra's 81.1. Low at 4K reaches 124.1 FPS, but the gain over Medium may not justify the visual downgrade.

Across all three resolutions, Medium settings offer the best balance of frame rate and quality. The data shows that Ultra settings consistently cost the most FPS — at 4K, Ultra is well below Medium — while Low settings provide diminishing returns over Medium. For players targeting high refresh rates, Medium at 1080p or 1440p is the recommended preset.

Measured FPS Breakdown

The full dataset of measured average FPS values is as follows:

At 3840x2160: Low settings average 124.1 FPS, Medium 111.5 FPS, High 98.4 FPS, and Ultra 81.1 FPS.

At 2560x1440: Low settings average 213.1 FPS, Medium 193.9 FPS, High 170 FPS, and Ultra 139.1 FPS.

At 1920x1080: Low settings average 320.8 FPS, Medium 292.8 FPS, High 259 FPS, and Ultra 208.8 FPS.

The ordering is consistent across resolutions: Low always produces the highest FPS, followed by Medium, then High, with Ultra lowest. The relative gaps, however, change with resolution. At 1080p, the difference between Low and Ultra is large. At 1440p, that gap narrows. At 4K, it shrinks further. This compression of the settings spread at higher resolutions reinforces the conclusion that the GPU becomes the dominant constraint as pixel count increases.

How This Combo Ranks

The Intel Core i7-14700K and AMD Radeon RX 6650 XT combination is ranked 1116 out of 1800 tested combos in Roblox. This places the combo in the lower portion of the field, despite the CPU's strong individual performance. The CPU's 96th percentile ranking and the GPU's 72nd percentile ranking suggest a mismatch: the processor is far more capable than the graphics card in this pairing.

The rank reflects the game's behavior. Roblox's measured FPS at 1080p is high — 259 at High settings — but the combo's overall standing is dragged down by the GPU's limitations at higher resolutions. The data implies that pairing the i7-14700K with a stronger GPU would likely improve the combo's rank, since the CPU has headroom to spare. As it stands, the RX 6650 XT caps performance at 4K, where even Low settings only reach 124.1 FPS.

The rank of 1116 out of 1800 means the combo sits below the midpoint of the field. The CPU's nearest rivals — the i7-14700KF, EPYC 9115, Ryzen 9 9950X, and Xeon Platinum 8270 — all sit within 1.4% of its average score, so the processor is not the differentiator. The GPU's nearest rivals are similarly clustered, with deltas under 0.6%. The combo's mid-pack rank in Roblox is therefore a product of the specific balance between this CPU and GPU, not a reflection of either component's individual standing.
