Minimum

The Intel Core i5-9400 and AMD Radeon RX 6650 XT combination ranks 1138 out of 1733 tested combos in Minimum — a result that places it just past the 65th percentile of all tested systems. This mid-pack positioning is consistent with the component pair's individual standings: the CPU sits at the 50th percentile among all processors, while the GPU lands at the 72nd percentile among all graphics cards. The gap between those two percentile figures hints at a system where the processor is the more likely constraint, and the measured frame rates across resolutions confirm that interpretation.

How This Combo Ranks

The combo's rank of 1138 out of 1733 in Minimum means roughly two-thirds of tested configurations outperform it, but it also means the i5-9400 + RX 6650 XT beats about 595 other combos. That puts this pairing in the solidly mainstream tier — not a top-tier competitor, but far from the bottom. The GPU's 72nd percentile standing versus the CPU's 50th percentile suggests the graphics card is the stronger component in this pairing, yet the system still lands in the upper-middle of the pack overall. Benchmark data shows the CPU's average score of 2305 is nearly identical to its nearest rivals: the Intel Core i3-10305 (2300, delta 0.2%), the Intel Core i3-1125G4 (2299, delta 0.2%), and the Intel Xeon E-2134 (2295, delta 0.4%). The only nearby chip that edges it out is the Intel Core i7-8809G (2319, delta -0.6%). Meanwhile, the GPU's average benchmark score of 29024 is essentially tied with the AMD Radeon RX 6800M (29011, delta 0%) and AMD Radeon RX 470 (28996, delta 0.1%), while slightly trailing the Intel Arc A370M (29175, delta -0.5%) and AMD Radeon RX Vega M GH (29197, delta -0.6%). These near-dead heats in synthetic benchmarks translate into a combo that sits squarely in the middle of the tested field for Minimum.

GPU Role

The AMD Radeon RX 6650 XT brings 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. Its clock behavior is notable: a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. The memory runs at 2190 MHz with 17.5 Gbps effective speed. The card's raw throughput numbers — 10.79 TFLOPS FP32, 337.3 GTexel/s texture rate, and 168.6 GPixel/s pixel rate — are backed by 2048 shading units, 128 TMUs, and 64 ROPs. In Minimum, the GPU's influence is most visible in the scaling between settings presets. At 1080p, moving from Low to Ultra costs 89.7 FPS (from 176.3 down to 86.6), a 51% drop. At 1440p, the same preset swing costs 55.6 FPS (113.7 to 58.1), a 49% drop. At 4K, the swing narrows to 27.8 FPS (58.9 to 31.1), a 47% drop. This consistent percentage decline across resolutions indicates the GPU is the primary driver of setting-based performance changes — the card's compute resources scale predictably with workload, and the CPU is not forcing diminishing returns at higher settings.

Resolution Scaling

The measured FPS data shows a clear pattern: resolution scaling hits this combo hard, and the rate of decline points to the CPU becoming a bottleneck at lower resolutions. From 1080p High (114.3 FPS) to 1440p High (73 FPS), the drop is 36%. From 1440p High to 4K High (37.2 FPS), the drop is another 49%. The Low preset tells a similar story: 176.3 FPS at 1080p, 113.7 at 1440p (a 36% drop), then 58.9 at 4K (a 48% drop from 1440p). The fact that the percentage loss between 1080p and 1440p is nearly identical to the loss between 1440p and 4K — around 36% in both cases — suggests the GPU is the limiting factor across the board. However, the absolute numbers tell a different tale at 1080p: the Low preset's 176.3 FPS is high enough that the i5-9400's six cores and six threads, running at a base of 2.90 GHz and boost of 4.10 GHz, may start to cap frame generation. At 4K Low (58.9 FPS), the GPU is clearly the constraint, as the CPU has ample headroom at that frame rate. The data shows a system where the RX 6650 XT is the workhorse, but the i5-9400's mid-range standing (50th percentile) means it cannot fully stretch its legs at lower resolutions and settings.

FAQ

*Q: How does this combo perform in Minimum at 1080p with High settings?*

A: The measured average FPS is 114.3, which is well above the 60 FPS threshold and indicates smooth gameplay for most scenarios. This is 27.7 FPS higher than the 86.6 FPS seen at Ultra settings, suggesting High is a comfortable spot for this resolution.

Q: What is the biggest FPS drop when increasing resolution?

A: Moving from 1080p High (114.3 FPS) to 1440p High (73 FPS) represents a 41.3 FPS loss, or about 36%. The next step, from 1440p High to 4K High (37.2 FPS), loses another 35.8 FPS, again around 49%. The proportional losses are similar, indicating the GPU handles the resolution scaling consistently.

Q: Is the CPU or GPU the limiting factor in this combo?

A: Benchmark percentiles show the GPU at 72nd place versus the CPU at 50th, which suggests the processor is the weaker link. The FPS data supports this: at 1080p Low, the combo hits 176.3 FPS, but at 4K Low it drops to 58.9 FPS — a 117.4 FPS difference that is almost entirely attributable to the GPU's workload at higher resolutions.

Q: How does the RX 6650 XT compare to its nearest GPU rivals?

A: The GPU's average benchmark score of 29024 is within 0.6% of all four nearest rivals. The AMD Radeon RX 6800M (29011) and AMD Radeon RX 470 (28996) are essentially tied, while the Intel Arc A370M (29175) and AMD Radeon RX Vega M GH (29197) are marginally ahead by about 0.5%.

Q: What is the best resolution for this combo to maintain 60+ FPS?

A: At 1440p, all presets except Ultra stay above 60 FPS: Low hits 113.7, Medium 89.1, and High 73. At 4K, only Low (58.9 FPS) comes close to 60, while Medium (46.6) and High (37.2) fall short. The data indicates 1440p High is the highest quality setting that reliably exceeds 60 FPS.

Q: How does the i5-9400's single-core performance compare to its multi-core?

A: The CPU scores 1125 in Cinebench R23 single-core and 7969 in multi-core, which is a ratio of about 7.1x. In Cinebench R20, the single-core score is 472 against 3346 multi-core, a 7.1x ratio as well. This consistent scaling suggests the six physical cores are being utilized effectively, though the 50th percentile standing indicates it is not a top-tier performer.

CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor based on the Coffee Lake architecture, built on Intel's 14 nm process. It runs at a base clock of 2.90 GHz with a boost clock of 4.10 GHz, and it pulls a 65 W TDP. The cache layout includes 64 KB L1 and 256 KB L2 per core, plus a shared 9 MB L3 cache. Memory support is DDR4 in dual-channel configuration, providing 42.7 GB/s of bandwidth. In Minimum, the CPU's role is most evident when examining the frame rate ceiling at lower resolutions. At 1080p Low, the combo produces 176.3 FPS, which is the highest measured result across all configurations. At 1440p Low, the number drops to 113.7 FPS — a 36% reduction that mirrors the resolution scaling seen at High settings. This consistency suggests the CPU is not introducing a bottleneck at these frame rates; the GPU is doing the heavy lifting. However, the CPU's 50th percentile standing and its near-tie with the Core i3-10305 (2300, delta 0.2%) indicate it is not a high-end part. In synthetic tests, the i5-9400 scores 803 in Cinebench R15 multi-core and 113 in single-core, with R20 results of 3346 and 472 respectively. These numbers place it firmly in the mid-range, and the measured FPS in Minimum reflects that: the combo can push high frame rates, but it does not top the charts.

Settings Recommendations

The measured FPS data provides a clear hierarchy for settings presets at each resolution. At 1080p, all four presets exceed 60 FPS: Low hits 176.3, Medium 133.9, High 114.3, and Ultra 86.6. The gap between High and Ultra is 27.7 FPS, which is the largest jump between consecutive presets at this resolution, suggesting Ultra demands significantly more GPU resources. At 1440p, the story changes: Low (113.7) and Medium (89.1) are comfortable, High (73) is playable, but Ultra drops to 58.1 FPS — just below the 60 FPS threshold. At 4K, only Low (58.9) approaches 60 FPS, with Medium (46.6), High (37.2), and Ultra (31.1) all falling substantially short. For the best experience, the data points to 1440p High as the sweet spot: it delivers 73 FPS, which is 14.9 FPS above the 4K High result and 41.3 FPS below the 1080p High result, but offers a significant visual quality jump over 1080p. If 60 FPS is the target, 1440p High is the highest quality preset that maintains it. For players prioritizing frame rate over visuals, 1080p Ultra (86.6 FPS) or 1440p Low (113.7 FPS) are both viable, but the former provides a more balanced experience. At 4K, the only option that stays close to 60 FPS is Low at 58.9 FPS, and even that is slightly under. The benchmark results indicate this combo is best suited for 1080p or 1440p gaming, with 4K reserved for lower settings or less demanding scenes.
