Roblox

The data for Roblox with the Intel Core i5-10400F and AMD Radeon RX 6650 XT shows a configuration that is heavily weighted toward the graphics card, though the CPU still plays a notable supporting role. The measured FPS across the board is exceptionally high, with the lowest average recorded at 79.4 FPS in 4K Ultra settings. This combination is clearly capable of running the game at playable framerates even under the most demanding settings tested.

Resolution Scaling

The performance drop from 1080p to 4K is substantial but not drastic, which reveals the balance of this system. At 1080p Low settings, the combo achieves 320 FPS, which drops to 122.8 FPS at 4K Low, a reduction of roughly 62%. For Ultra settings, the drop is from 209.8 FPS at 1080p to 79.4 FPS at 4K, a decrease of approximately 62% as well. This consistent scaling factor indicates that the GPU is the primary limiting component as resolution increases.

Looking at the intermediate step, 1440p sits almost exactly between the two extremes. At 1440p High, the system produces 171.5 FPS, while 1080p High yields 257.3 FPS and 4K High drops to 97.9 FPS. The frame rate curve is not linear; the jump from 1440p to 4K costs more performance than the jump from 1080p to 1440p. For instance, moving from 1080p to 1440p at High settings reduces FPS by 85.8, while moving from 1440p to 4K reduces it by 73.6. This suggests the GPU’s memory bandwidth and compute resources become more strained as pixel count grows.

The data also shows that settings quality has a significant impact at every resolution. At 4K, the spread between Low (122.8 FPS) and Ultra (79.4 FPS) is 43.4 FPS. At 1080p, the spread is 110.2 FPS, from 320 FPS on Low to 209.8 FPS on Ultra. The larger absolute gap at lower resolutions indicates that the CPU can still feed the GPU enough data to let the graphics settings fully express their impact on the render workload.

GPU Role

The AMD Radeon RX 6650 XT features 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 280.3 GB/s. Its boost clock is rated at 2635 MHz, with a game clock of 2410 MHz. These specifications align with the observed performance, as the card maintains high frame rates even at 4K, where memory bandwidth becomes more critical. The card’s 2048 shading units and 64 ROPs are sufficient for Roblox’s rendering demands, which are relatively light compared to many modern AAA titles.

The GPU’s average benchmark score is 29024, placing it in the 72nd percentile of all GPUs. Its nearest rival is the AMD Radeon RX 6800M, with a deltaPct of 0%, meaning the two perform identically in aggregate benchmarks. This is notable because the RX 6800M is a mobile part, while the RX 6650 XT is a desktop card, yet their average scores are effectively tied. The RX 470 is also within 0.1% of the RX 6650 XT, showing that the performance envelope here is well-established across multiple generations.

In Roblox specifically, the GPU is clearly the dominant factor in determining FPS, as evidenced by the sharp response to resolution changes. The 4K Ultra result of 79.4 FPS is the only point where the system dips below the 100 FPS threshold, indicating that the card is being pushed hard. The 8 GB frame buffer appears sufficient for this game, as no anomalies or severe drops beyond the expected scaling are present in the data.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all settings. Low settings yield 320 FPS, Medium settings yield 293.2 FPS, High settings yield 257.3 FPS, and Ultra settings yield 209.8 FPS. The difference between Low and Ultra is 110.2 FPS, showing that the GPU can handle the extra load without significant strain at this resolution.

At 2560x1440, the frame rates remain very high but start to show the impact of increased pixel count. Low settings produce 214.7 FPS, Medium produces 193.4 FPS, High produces 171.5 FPS, and Ultra produces 142 FPS. The gap between Low and Ultra narrows to 72.7 FPS, indicating that the GPU is beginning to feel the pressure of the higher resolution.

At 3840x2160, the system still maintains playable framerates across all settings. Low settings yield 122.8 FPS, Medium yields 107.3 FPS, High yields 97.9 FPS, and Ultra yields 79.4 FPS. The spread between Low and Ultra is 43.4 FPS, the smallest of any resolution, suggesting that at 4K the GPU is the clear bottleneck and settings adjustments have less relative impact.

The data shows a consistent pattern: every increase in resolution or settings quality results in a measurable, predictable drop in FPS. No anomalies appear, such as sudden dips or stalls, which indicates stable performance across the board.

How This Combo Ranks

In Roblox, this specific combination of the Intel Core i5-10400F and AMD Radeon RX 6650 XT ranks 1128 out of 1800 tested combos. This places it in the 62nd percentile of all configurations, meaning it outperforms more than half of the tested setups. Given the absolute frame rates are very high, this ranking suggests that other combos in the database are capable of even higher performance, likely due to more powerful GPUs or CPUs.

The GPU’s individual ranking is in the 72nd percentile, which is higher than the combo’s overall rank. This indicates that the CPU may be holding back the GPU to some degree in this game, preventing the combo from climbing higher in the rankings. Conversely, the CPU’s rank in the 73rd percentile is similar, so neither component is a weak link, but the combination does not push either to its absolute limit.

The nearest rival combos are not specified in the data, but the individual component rivals provide context. The GPU is tied with the RX 6800M and within 0.1% of the RX 470, while the CPU is within 1.2% of the Core i5-8500. These close margins suggest that swapping either component for a near-equivalent would not result in a dramatic change in Roblox performance.

CPU Role

The Intel Core i5-10400F has 6 cores and 12 threads, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. It belongs to the Comet Lake architecture and is built on a 14 nm process. Its L3 cache is 12 MB shared, and it supports DDR4 memory in dual-channel mode with a bandwidth of 42.7 GB/s. These specifications are modest by modern standards but more than sufficient for Roblox.

The CPU’s average benchmark score is 14168, placing it in the 73rd percentile of all CPUs. Its nearest rival is the AMD EPYC 7552, which has a deltaPct of 0.4%, meaning the i5-10400F is slightly ahead. The Ryzen 3 7320C and Core i5-8500 are within 1.1% behind, indicating that this CPU is in a tight performance cluster with several other parts.

In Roblox, the CPU’s role is less obvious than the GPU’s, but it still matters. At 1080p Low, the system hits 320 FPS, which is near the limits of what most displays can show. This high frame rate suggests the CPU is not a bottleneck at lower resolutions. However, the fact that the combo rank is lower than the GPU’s percentile suggests that the CPU might limit performance in certain scenes or when many objects are on screen. The 6-core, 12-thread configuration is likely sufficient for Roblox’s physics and scripting workloads, but it does not provide the headroom that a higher-end CPU might offer. The single-thread benchmark score of 688 in 3dMark indicates decent per-core performance, which is important for a game that may not utilize all threads efficiently.
