Roblox

Roblox is a Sandbox title, and the combo under review is the Intel Core i5-14400F (launch MSRP $196) with the AMD Radeon RX 5700 XT (launch MSRP 399 USD). The FPS entries are flagged dataIsMeasured: true, so the measuredFps rows below are direct benchmark results rather than estimates.

Resolution Scaling

The measured FPS curve moves as both resolution and settings increase. At Low settings, average FPS drops from 304.4 at 1920x1080 to 202 at 2560x1440 and then 117.7 at 3840x2160. The Ultra preset follows the same path: 196.6 at 1920x1080, 130.5 at 2560x1440, and 73.6 at 3840x2160. High settings produce 242.3 at 1080p, 164.1 at 1440p, and 90.3 at 4K. Medium settings sit between High and Low at every resolution, with 274, 182.3, and 101.9 respectively.

The drop from 1080p to 4K is steady across all presets, which points to the GPU becoming the dominant limiting component as pixel count rises. At 4K, the Ultra preset lands at 73.6 fps while even 4K Low reaches 117.7 fps, a large margin that is still present at 1440p and 1080p. The data shows the i5-14400F has enough throughput to feed very high frame rates at 1080p, but by 4K the Radeon RX 5700 XT is carrying the heavier load. This behavior is typical of a GPU-bound scaling curve, especially when Low-to-Ultra differences remain visible at every resolution.

GPU Role

The AMD Radeon RX 5700 XT is the component that scales with Roblox’s rendering settings. It has 8 GB of GDDR6 memory on a 256-bit bus with 448.0 GB/s bandwidth. Its RDNA 1.0 architecture has a base clock of 1605 MHz, a game clock of 1755 MHz, and a boost clock of 1905 MHz. The GPU contains 2560 shading units, 160 texture mapping units, and 64 ROPs, with FP32 performance rated at 9.754 TFLOPS.

In synthetic benchmarks, the RX 5700 XT scores 24731 average, sits at the 68th percentile of all GPUs, and posts a Passmark G3D score of 16277. That mid-high synthetic position lines up with Roblox results: the GPU holds 4K High at 90.3 fps, 4K Medium at 101.9 fps, and 4K Low at 117.7 fps. Only the 4K Ultra preset drops to 73.6 fps. The 8 GB frame buffer and 448.0 GB/s bandwidth are enough to keep high resolutions playable in this title, and the measured results show that the GPU becomes the limiting factor when settings are pushed to Ultra at 4K.

Compared with nearest rivals, the RX 5700 XT averages 24731, 0.1% behind the NVIDIA RTX A5000 Mobile, 0.3% ahead of the Intel Arc A350M, 0.6% ahead of the NVIDIA GeForce RTX 5060 Mobile, and 0.9% ahead of the NVIDIA Quadro RTX 5000. In actual Roblox play, those small synthetic deltas are less important than the measured FPS list, which shows no resolution/setting combination with an average below 73.6 fps.

CPU Role

The Intel Core i5-14400F supplies the CPU side of this pairing. It has 10 cores and 16 threads, a base clock of 2.50 GHz, a boost clock of 4.70 GHz, 20 MB of shared L3 cache, and a TDP of 65 W. The chip is built on a 10 nm process and supports DDR4 and DDR5 memory in dual-channel mode. Its synthetic profile is strong: Passmark multithread scores 25783, Passmark single thread scores 3723, and Cinebench R23 multicore scores 21914 with a singlecore score of 3093. Geekbench results are 11209 multicore and 2333 singlecore.

In Roblox, the CPU does not appear to be the primary limiter at higher framerates. At 1080p Low, the combo averages 304.4 fps, and even 1080p Ultra averages 196.6 fps. At 1440p Low the average remains 202 fps, and 1440p Ultra stays at 130.5 fps. These numbers indicate the i5-14400F can keep up with the RX 5700 XT at standard desktop resolutions and high refresh rates. The CPU’s 88th percentile ranking among all CPUs and average benchmark score of 32508 support that conclusion. Its nearest rivals in aggregate performance are the Intel Core i7-12800H with a deltaPct of 0, the AMD Ryzen 5 PRO 7645 with a deltaPct of 0.2, the AMD Ryzen 7 250 with a deltaPct of -0.2, and the Intel Core i7-13705H with a deltaPct of -0.2. In short, this processor is not what holds the combo back in Roblox.

The dataset only reports average FPS for these entries. The minFps and maxFps fields are null in every row, so this breakdown is strictly based on mean performance.

How This Combo Ranks

In the benchmark database, this combination ranks 1380 out of 1800 tested combos in Roblox. That places it behind a large portion of the tested field, but the measured FPS shows a generally smooth experience. The CPU sits at the 88th percentile among all CPUs, while the GPU sits at the 68th percentile among all GPUs. The in-game combo rank of 1380 out of 1800 is noticeably lower than those component percentiles would suggest.

This gap indicates that Roblox’s workload does not reward raw synthetic CPU and GPU scores in a straightforward way. A combo can have strong individual component percentiles and still rank lower in a specific game due to that game’s particular balance of CPU and GPU demands. The measured Roblox data still shows high averages across all tested resolutions and settings, with the weakest average being 73.6 fps at 4K Ultra. So while the rank is not near the top, the actual frame-rate data does not reveal any broken or severely underperforming configuration.
