# How This Combo Ranks

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 6650 XT lands at rank 2431 out of 3723 tested combinations in Pc Building Simulator. That places this build in the 35th percentile of all combos tested, meaning roughly 65% of configurations deliver higher average frame rates in this simulation title. The ranking reflects a mid-tier pairing that prioritizes balance over raw throughput.

Benchmark results indicate this combo sits in a crowded performance band. The CPU's average benchmark score of 25005 places it within 0.4% of the AMD Ryzen 5 7500F (deltaPct 0.2) and within 0.3% of the Intel Core i7-11850H. On the GPU side, the Radeon RX 6650 XT's average score of 19765 puts it nearly neck-and-neck with the NVIDIA Tesla K40m (deltaPct -0.6) and the AMD FirePro W7000 (deltaPct -0.7). Neither component dominates its peer group; instead, both hover around parity with direct competitors.

What matters for Pc Building Simulator is how these two pieces interact. The game is a simulation title where frame pacing and consistency often matter more than peak output. The measured data shows this combo can push high frame rates at lower settings, but it struggles to maintain smooth performance at 4K Ultra. The rank of 2431 reflects that the pair is competent but not exceptional—it delivers playable results across most configurations, yet it never breaks into the upper echelon of tested hardware.

In practical terms, this combo behaves like a well-matched mid-range system. The CPU's 77th percentile ranking among all processors suggests it has headroom for more demanding titles, while the GPU's 65th percentile ranking indicates it is the more limiting factor in this pairing. For a game like Pc Building Simulator, which is not graphically intensive by modern standards, the combination provides a comfortable baseline without excessive overhead.

Settings Recommendations

The measured FPS data reveals a clear hierarchy across the four presets tested. At 1920x1080, the Low preset delivers an average of 234 FPS, which drops to 165 FPS at Medium, 117 FPS at High, and 111 FPS at Ultra. The gap between High and Ultra is modest—only 6 FPS—suggesting diminishing returns at the top end. This pattern repeats at 2560x1440, where Low averages 147 FPS, Medium 104 FPS, High 74 FPS, and Ultra 70 FPS. At 3840x2160, the spread widens dramatically: Low averages 77 FPS, Medium 55 FPS, High 39 FPS, and Ultra 37 FPS.

For the best experience, the Medium preset stands out as the sweet spot. At 1080p, it delivers 165 FPS average with a minimum of 141 FPS and maximum of 190 FPS—the only preset at this resolution with full min/max data. The 141 FPS floor ensures consistent frame delivery even during complex scenes. Moving to 1440p, Medium maintains 104 FPS average with a minimum of 89 FPS, which remains comfortably above the 60 FPS threshold for smooth gameplay. At 4K, Medium drops to 55 FPS average with a 46 FPS minimum, which is borderline but acceptable for a simulation genre.

The Ultra preset offers little over High in return for the performance cost. At 1080p, the difference is only 6 FPS (111 vs 117). At 1440p, it is 4 FPS (70 vs 74). At 4K, it is 2 FPS (37 vs 39). These margins fall well within measurement noise. The data suggests High is the more sensible choice if visual fidelity matters, as it captures nearly all the visual benefit of Ultra without the frame rate penalty. However, Medium provides the best balance of smoothness and visual quality across all resolutions, particularly for players who prioritize consistent frame times over maximum detail.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals where the bottleneck lies. At Low settings, the progression is 234 FPS (1080p) → 147 FPS (1440p) → 77 FPS (4K). This represents a 37% drop from 1080p to 1440p and a 48% drop from 1440p to 4K. At Medium settings, the progression is 165 FPS → 104 FPS → 55 FPS, with drops of 37% and 47% respectively. At High settings, it is 117 FPS → 74 FPS → 39 FPS, with drops of 37% and 47%. At Ultra, it is 111 FPS → 70 FPS → 37 FPS, with drops of 37% and 47%.

The consistency of these percentage drops across all settings is telling. Regardless of whether the game runs at Low or Ultra, the relative performance degradation from resolution scaling remains nearly identical. This pattern indicates that the GPU is the limiting component as resolution increases. The Radeon RX 6650 XT's 8 GB of GDDR6 memory on a 128-bit bus with 280.3 GB/s bandwidth becomes progressively more strained as pixel count grows, while the CPU's workload remains relatively constant.

The CPU's capability is evident in the 1080p Low result of 234 FPS. That figure shows the Ryzen 5 8400F can feed frames far faster than the GPU can render them at higher resolutions. The 6-core, 12-thread processor with a 4.70 GHz boost clock provides ample headroom for the simulation's logic and physics calculations. At 1080p Low, the GPU is the clear constraint, as evidenced by the 234 FPS ceiling. As resolution climbs, the GPU's pixel throughput becomes the dominant factor, and the CPU's role recedes.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 234 FPS. Medium settings yield 165 FPS average, with a minimum of 141 FPS and maximum of 190 FPS. High settings average 117 FPS, while Ultra settings average 111 FPS. The 1080p results show that even the most demanding preset stays well above the 100 FPS mark, making this resolution entirely comfortable for the hardware.

At 2560x1440, performance remains solid but begins to show the GPU's limitations. Low settings average 147 FPS. Medium settings produce 104 FPS average, with a minimum of 89 FPS and maximum of 120 FPS. High settings drop to 74 FPS average, and Ultra settings fall to 70 FPS. The Medium preset at 1440p still clears the 60 FPS threshold with room to spare, but High and Ultra approach the boundary where frame drops become noticeable.

At 3840x2160, the combo struggles to maintain high frame rates. Low settings average 77 FPS, which is playable but no longer silky smooth. Medium settings average 55 FPS, with a minimum of 46 FPS and maximum of 63 FPS. The 46 FPS minimum indicates occasional dips below the 60 FPS target. High settings drop to 39 FPS average, and Ultra settings fall to 37 FPS. At 4K, only the Low preset provides a consistently smooth experience; Medium is borderline, and High/Ultra are not recommended for competitive or fast-paced play.

The min/max data available for Medium settings across all three resolutions provides insight into frame consistency. At 1080p, the range is 141-190 FPS (a 49 FPS spread). At 1440p, it is 89-120 FPS (a 31 FPS spread). At 4K, it is 46-63 FPS (a 17 FPS spread). The narrowing range at higher resolutions suggests that as the GPU becomes more saturated, frame times become more uniform—fewer extreme spikes but also less headroom for demanding scenes.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on TSMC's 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. It supports dual-channel DDR5 memory with a bandwidth of 83.2 GB/s and connects via PCIe Gen 4 with 20 lanes.

In Pc Building Simulator, the CPU's role is primarily to manage game logic, component simulation, and system interactions. The 1080p Low result of 234 FPS demonstrates that the CPU has significant headroom. Its single-thread performance is solid, as shown by the 3dmark single-thread score of 951 and Cinebench R23 single-core score of 2943. Multi-threaded performance is equally capable, with a Cinebench R23 multi-core score of 20851 and a Passmark multithread score of 24389.

The CPU's 77th percentile ranking among all processors places it above most mainstream chips. Its nearest rivals include the AMD Ryzen 5 7500F (deltaPct 0.2) and Intel Core i7-11850H (deltaPct 0.3), both of which deliver nearly identical average benchmark scores. The 8400F's advantage in this game is its strong single-thread performance, which helps maintain high frame rates even when the GPU is not saturated. At 1080p, the CPU never appears to be the limiting factor; the GPU's 8 GB VRAM and 2048 shading units cap performance well before the CPU reaches its limits.

The 4 nm process and 25,000 million transistors on a 178 mm² die contribute to the CPU's efficiency and responsiveness. With 12 threads available, the processor can handle background tasks and game threads simultaneously without contention. The data supports the conclusion that the Ryzen 5 8400F is more than adequate for this simulation title, providing a stable foundation for the GPU to operate within its own constraints.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, manufactured on TSMC's 7 nm process. It features 8 GB of GDDR6 memory on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The GPU operates with a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. It contains 2048 shading units, 128 texture mapping units, and 64 raster operations pipelines, along with 32 ray tracing cores.

In Pc Building Simulator, the GPU's performance profile is defined by its memory subsystem and compute capabilities. The 8 GB VRAM is sufficient for this game at all tested settings, as memory capacity is not the constraint. Instead, the 128-bit memory bus and 280.3 GB/s bandwidth limit texture throughput and fill rate as resolution increases. The pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s become the determining factors at 4K, where the GPU's 39 FPS average at High settings reflects these bandwidth limitations.

The GPU's 65th percentile ranking among all graphics cards places it in the mid-range category. Its nearest rivals include the NVIDIA Tesla K40m (deltaPct -0.6) and AMD FirePro D300 (deltaPct 0.7), which show the 6650 XT is neither ahead nor behind its direct competitors by a meaningful margin. The FP32 performance of 10.79 TFLOPS provides adequate compute for the simulation's rendering requirements, but the 176 W TDP and dual-slot cooler design indicate this is a power-conscious mid-range part.

The GPU's role as the primary bottleneck at higher resolutions is clearly demonstrated by the resolution scaling data. The consistent 37% frame drop from 1080p to 1440p and 47% drop from 1440p to 4K across all settings points to the GPU's pixel throughput as the limiting factor. At 1080p, the GPU can deliver 234 FPS at Low settings, but this drops to 111 FPS at Ultra—a 53% reduction that shows the shading units and ROPs are strained by increased graphical complexity. The 8 GB memory capacity is not the issue; rather, the 128-bit interface restricts how quickly data can be fed to the compute units.
