FAQ

Q: Is this combo capable of 60+ FPS at 4K Ultra in Pc Building Simulator?

A: Yes. The measured average FPS at 3840x2160 Ultra is 62 FPS, just clearing the 60 FPS threshold. High settings at 4K yield 65 FPS average, while Medium settings push to 93 FPS.

Q: How does this combo rank among all tested configurations in this game?

A: This combo ranks 718 out of 3,723 tested combinations, placing it in the top 19.3% of all recorded pairings for Pc Building Simulator.

Q: What is the single best performance result in this dataset?

A: The highest measured average FPS is 346, achieved at 1920x1080 with Low settings. The lowest measured average is 62 FPS at 3840x2160 Ultra.

Q: Does the CPU limit performance at any resolution?

A: Yes. At 1080p, frame rates across all settings cluster tightly between 189 and 346 FPS, which suggests the i3-12100F's 4 cores/8 threads cap performance well before the RX 7900 XT's full potential. The GPU's memory bandwidth of 800.0 GB/s and 51.48 TFLOPS compute would otherwise support far higher output.

Q: What is the frame time consistency like at Medium settings?

A: The dataset includes min/max FPS only for Medium settings. At 1080p Medium, the range is 238 to 323 FPS (average 281). At 1440p Medium, the range is 150 to 204 FPS (average 177). At 4K Medium, the range is 79 to 106 FPS (average 93). These ranges indicate generally stable frame pacing.

Q: How does the RX 7900 XT's benchmark standing compare to its nearest rivals?

A: The GPU's average benchmark score is 13,745, which places it 0.5% behind the AMD Radeon 660M (13,812), 0.5% behind the NVIDIA RTX A2000 Mobile (13,821), and 0.9% behind the AMD Radeon RX 570X (13,871). It sits 1.5% ahead of the AMD Radeon RX 9070 XT (13,543).

GPU Role

The AMD Radeon RX 7900 XT brings substantial graphics resources to this pairing. Its 20 GB of GDDR6 memory on a 320-bit bus delivers 800.0 GB/s of bandwidth, which is more than sufficient for a simulation game like Pc Building Simulator at any resolution tested. The GPU's boost clock of 2394 MHz and game clock of 2025 MHz drive 5,376 shading units across 336 TMUs and 192 ROPs.

The data shows the GPU's headroom is only fully exercised at 4K. At 3840x2160 Ultra, the average FPS drops to 62, indicating the GPU is now the primary limiter. At 4K Low, the average jumps to 131 FPS, and at 4K Medium it reaches 93 FPS. This scaling pattern — from 62 FPS at Ultra to 131 FPS at Low — demonstrates that the RX 7900 XT responds strongly to settings reductions when resolution pressure is high.

However, the GPU's benchmark percentiles tell a nuanced story. The RX 7900 XT sits at the 55th percentile versus all GPUs, with an average benchmark score of 13,745. Its nearest rivals include integrated and mobile parts (AMD Radeon 660M, RTX A2000 Mobile, RX 570X), which suggests the benchmark methodology may not fully capture this card's gaming strengths. The 3DMark Steel Nomad DX12 score of 5,623 and Geekbench Vulkan score of 71,068 indicate strong modern API performance, but the PassMark DirectX 12 score of 110 appears anomalously low relative to other metrics.

The GPU's 84 ray accelerators and DirectX 12 Ultimate support (12_2) provide modern feature coverage, though Pc Building Simulator's simulation-focused workload likely relies more on rasterization throughput than ray tracing. The 459.6 GPixel/s pixel rate and 804.4 GTexel/s texture rate give the card ample fill-rate capacity for the game's interface-heavy rendering.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor built on Intel's 10 nm Alder Lake architecture. It operates with a base clock of 3.30 GHz and a boost clock of 4.30 GHz, with 12 MB of shared L3 cache. This is a modest CPU by modern standards, sitting at the 68th percentile versus all CPUs with an average benchmark score of 13,494.

In Pc Building Simulator, the CPU's influence is most visible at 1080p. The measured FPS at 1920x1080 ranges from 189 FPS (Ultra) to 346 FPS (Low), with Medium at 281 FPS and High at 198 FPS. The gap between Low and Medium is 65 FPS, but the gap between Medium and High is 83 FPS, and between High and Ultra is only 9 FPS. This irregular scaling pattern is characteristic of CPU-bound operation — the i3-12100F cannot push frame rates higher regardless of GPU settings reductions.

The CPU's multithreaded benchmark scores confirm its mid-range standing. Cinebench R23 multicore scores 11,860, while single-core scores 1,674. Geekbench multicore reaches 7,252 with single-core at 1,932. PassMark multithread scores 14,015 with single-thread at 3,444. These numbers place the i3-12100F in close competition with the Intel Core 3 N355 (13,492, 0% delta), Intel Core i5-9500 (13,452, 0.3% ahead), Intel Core 5 120UL (13,594, 0.7% behind), and Intel Core i7-1250U (13,351, 1.1% ahead).

For a simulation game, the CPU's 4 cores and 8 threads provide adequate logical processor count, but the lack of additional physical cores becomes apparent at lower resolutions where GPU headroom exists. The 58 W TDP and dual-channel DDR4/DDR5 memory support keep the platform simple, but the CPU's 12 MB L3 cache is relatively small for modern workloads.

How This Combo Ranks

This Intel i3-12100F + AMD RX 7900 XT combination ranks 718 out of 3,723 tested combos in Pc Building Simulator. That places it in the top 19.3% of all configurations, which is respectable given the CPU's modest specifications alongside a high-end GPU.

The ranking reflects the imbalance in this pairing. The GPU alone sits at the 55th percentile versus all GPUs, while the CPU sits at the 68th percentile versus all CPUs. Yet the combo rank of 718/3,723 (top 19.3%) is better than either component's individual percentile standing might suggest. This is because Pc Building Simulator's workload appears to favor GPU throughput at higher resolutions, where the RX 7900 XT's 20 GB VRAM and 800.0 GB/s bandwidth come into play.

The 4K results are the strongest argument for this pairing. At 4K Ultra, the combo achieves 62 FPS average, which is playable. At 4K High, it reaches 65 FPS. The GPU's 20 GB memory capacity ensures no VRAM-related stuttering or texture thrashing at any settings level in this game. The 4K Medium result of 93 FPS with a 79-106 FPS range shows comfortable headroom above the 60 FPS target.

At 1440p, the combo is firmly in high-refresh territory. Ultra settings produce 119 FPS average, High produces 125 FPS, Medium produces 177 FPS, and Low produces 250 FPS. These numbers suggest the pairing is well-suited for 1440p high-refresh monitors, provided the game's simulation logic doesn't introduce CPU-bound frame pacing issues.

The 1080p results are where the CPU limitation becomes stark. The 346 FPS Low result is the only triple-digit-plus outlier; the other settings cluster between 189 and 281 FPS. For competitive or high-refresh 1080p gaming, this combo would leave performance on the table, but for a simulation title, these frame rates are far beyond what the game requires.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear shift in bottleneck behavior. At 1080p Low, the combo produces 346 FPS. At 1440p Low, that drops to 250 FPS (a 27.7% reduction). At 4K Low, it falls to 131 FPS (a 47.6% reduction from 1440p). This progressive decline with increasing resolution is typical of a GPU that becomes more loaded as pixel count rises.

The scaling pattern at Ultra settings tells a different story. At 1080p Ultra, the average is 189 FPS. At 1440p Ultra, it's 119 FPS (a 37% drop). At 4K Ultra, it's 62 FPS (a 47.9% drop from 1440p). The consistency of these percentage drops across settings levels — roughly 27-37% from 1080p to 1440p and 47-48% from 1440p to 4K — indicates that the GPU is the dominant scaling factor at Ultra settings.

At Medium settings, the scaling is more dramatic. 1080p Medium produces 281 FPS, 1440p Medium produces 177 FPS (a 37% drop), and 4K Medium produces 93 FPS (a 47.5% drop from 1440p). The 4K Medium result of 93 FPS is notably higher than the 4K Ultra result of 62 FPS, showing that settings reduction provides meaningful headroom at high resolutions.

The key insight from resolution scaling is that the CPU bottleneck at 1080p is absolute. The 346 FPS Low result at 1080p is 38% higher than the 250 FPS Low result at 1440p, but the 1440p to 4K drop of 47.6% is much larger. This indicates that at 1080p, the i3-12100F's 4 cores and 8 threads are saturated, and the RX 7900 XT is waiting on CPU data. At 4K, the GPU's rendering load becomes the limiting factor, and the CPU has enough headroom to feed it.

Measured FPS Breakdown

1920x1080 (1080p):

• Low settings: 346 FPS average
• Medium settings: 281 FPS average (range: 238-323 FPS)
• High settings: 198 FPS average
• Ultra settings: 189 FPS average

The 1080p results show the tightest grouping, with only a 157 FPS spread between Low and Ultra. The 9 FPS difference between High (198) and Ultra (189) suggests the CPU is the hard limiter at this resolution — GPU settings changes produce minimal FPS movement once the CPU's per-frame workload ceiling is reached.

2560x1440 (1440p):

• Low settings: 250 FPS average
• Medium settings: 177 FPS average (range: 150-204 FPS)
• High settings: 125 FPS average
• Ultra settings: 119 FPS average

At 1440p, the spread widens to 131 FPS between Low and Ultra. The drop from Medium to High is 52 FPS, and from High to Ultra is only 6 FPS. This pattern repeats the 1080p behavior at the high end, indicating the CPU still constrains the upper settings tiers. The Low and Medium results show the GPU responding to reduced load.

3840x2160 (4K):

• Low settings: 131 FPS average
• Medium settings: 93 FPS average (range: 79-106 FPS)
• High settings: 65 FPS average
• Ultra settings: 62 FPS average

At 4K, the full performance hierarchy emerges. The spread from Low to Ultra is 69 FPS, and each settings tier produces a meaningful step: Low to Medium is 38 FPS, Medium to High is 28 FPS, and High to Ultra is 3 FPS. The tiny gap between High (65) and Ultra (62) at 4K mirrors the 1080p pattern, suggesting that the Ultra preset's additional effects cost little on this GPU when the CPU is not the limiter.

The Medium settings results include min/max FPS data, which shows stable frame delivery across all three resolutions. The 4K Medium range (79-106 FPS) has a 27 FPS swing, the 1440p Medium range (150-204 FPS) has a 54 FPS swing, and the 1080p Medium range (238-323 FPS) has an 85 FPS swing. The proportional increase in frame time variance at lower resolutions is consistent with CPU scheduling variability under high FPS conditions.
