How This Combo Ranks

The combo's rank of 2060 out of 3723 tested configurations places it in the lower-middle portion of the overall distribution, yet the individual components tell a different story. The CPU's 95th percentile ranking suggests this is a processor with exceptional multi-threaded capability — its Cinebench R23 multi-core score of 42713 and single-core score of 6030 both reflect a high-end mobile part. The GPU's 75th percentile ranking is respectable but notably lower, indicating the graphics card is the limiting factor in this pairing.

The delta between CPU and GPU percentiles — 20 points — is substantial. In Pc Building Simulator, a simulation title that likely taxes both components differently depending on scene complexity, this imbalance manifests in the measured FPS scaling. At 1080p Low, the combo produces 262 FPS average, suggesting the CPU is capable of feeding the GPU at very high rates. At 4K Ultra, the average falls to 41 FPS, a 6.4x reduction from the 1080p Low figure, which points to GPU-bound operation at higher resolutions.

Compared to the nearest rival combos, this pairing's overall rank is unremarkable — it sits in the 55th percentile of all tested combos. However, the component-level data reveals that the CPU is performing near the top of its class while the GPU is merely average for its tier. This suggests that in CPU-light scenarios, the combo may punch above its overall rank, while in GPU-heavy scenarios it will fall toward the middle of the pack.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-bound scaling as resolution increases. From 1920x1080 to 2560x1440, the average FPS at High settings drops from 131 to 83, a 36.6% reduction. From 2560x1440 to 3840x2160, the High preset average falls from 83 to 43, a 48.2% reduction. The scaling is consistent across all settings presets.

At Low settings, the 1080p to 1440p drop is from 262 to 165 FPS (37.0% reduction), and the 1440p to 4K drop is from 165 to 86 FPS (47.9% reduction). This near-linear scaling with pixel count — 4K has 4x the pixels of 1080p, and the FPS drops by roughly 67% at Low settings — indicates the GPU is fully saturated at higher resolutions.

The Medium preset shows the most detailed data with min and max FPS values. At 1080p Medium, the average is 186 FPS with a range of 158 to 214. At 1440p Medium, the average is 117 FPS with a range of 100 to 135. At 4K Medium, the average is 61 FPS with a range of 52 to 70. The min-to-max spread narrows slightly as resolution increases, from 56 FPS at 1080p to 35 FPS at 1440p to 18 FPS at 4K, suggesting more consistent frame pacing at higher resolutions where the GPU is the bottleneck.

The Ultra preset shows the steepest scaling: 125 FPS at 1080p, 79 FPS at 1440p, and 41 FPS at 4K. The 1080p to 4K drop of 67.2% is nearly identical to the Low preset's 67.2% drop, confirming that resolution scaling is independent of settings in this title. The limiting component is clearly the GPU, as the CPU's 95th percentile ranking would not typically cause such consistent resolution-dependent FPS drops.

Measured FPS Breakdown

The full measured FPS table provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the Low preset delivers 262 FPS average, the highest figure in the dataset. Medium at 1080p yields 186 FPS (158 min, 214 max), High drops to 131 FPS, and Ultra yields 125 FPS. The gap between Medium and High is 55 FPS, while the gap between High and Ultra is only 6 FPS, suggesting diminishing returns at the top end.

At 2560x1440, the Low preset delivers 165 FPS, a 37% reduction from 1080p Low. Medium at 1440p yields 117 FPS (100 min, 135 max), High yields 83 FPS, and Ultra yields 79 FPS. The Medium-to-High gap narrows to 34 FPS, and the High-to-Ultra gap is 4 FPS. The Ultra preset at 1440p (79 FPS) is nearly identical to the High preset at 4K (43 FPS is not close; rather, 1440p Ultra at 79 FPS is close to 1080p Ultra at 125 FPS — a 36.8% drop).

At 3840x2160, the Low preset delivers 86 FPS, which is still playable for most users. Medium at 4K yields 61 FPS (52 min, 70 max), High yields 43 FPS, and Ultra yields 41 FPS. The Medium-to-High drop is 18 FPS, and the High-to-Ultra drop is only 2 FPS. The 4K Ultra figure of 41 FPS is the lowest average in the dataset, and the 4K High figure of 43 FPS is nearly identical, indicating that the Ultra preset offers negligible visual improvement over High at this resolution while costing 2 FPS.

The Medium preset is the only one with complete min/max data at all three resolutions. The spread at 1080p is 56 FPS (158-214), at 1440p is 35 FPS (100-135), and at 4K is 18 FPS (52-70). This tightening of the FPS range as resolution increases is characteristic of GPU-bound operation — at 1080p, the CPU may occasionally struggle to feed the GPU, causing wider variance; at 4K, the GPU is consistently the bottleneck, producing more stable frame times.

GPU Role

The NVIDIA GeForce RTX 5070 Mobile is a Blackwell 2.0 architecture part built on TSMC's 5 nm process. It features 4608 shading units, 144 texture mapping units, and 48 render output units, with 36 ray tracing cores and 144 tensor cores. The GPU's base clock is 907 MHz with a boost clock of 1425 MHz, and its memory operates at 1500 MHz (24 Gbps effective) across an 8 GB GDDR7 interface with a 128-bit bus, yielding 384.0 GB/s of bandwidth.

The GPU's average benchmark score of 29928 places it in the 75th percentile versus all GPUs. Its nearest rivals are all desktop parts: the RTX 3070 Ti (29945, 0.1% higher), RTX 2080 Ti (29783, 0.5% lower), RX 6800 (30095, 0.6% higher), and RX 6700 (30433, 1.7% higher). This places the mobile 5070 on par with several previous-generation desktop GPUs, which is notable for a mobile part with a 50 W TDP and IGP slot width.

In Pc Building Simulator, the GPU's role is clearly dominant at higher resolutions. The 4K results — 86 FPS at Low, 61 FPS at Medium, 43 FPS at High, and 41 FPS at Ultra — show that even a GPU performing at desktop-RTX-3070-Ti levels cannot maintain high frame rates at 4K with this title's demanding rendering. The 8 GB VRAM capacity is sufficient for the measured settings, as the data does not indicate any VRAM-related stuttering or performance collapse.

The GPU's pixel rate of 68.40 GPixel/s and texture rate of 205.2 GTexel/s provide context for the resolution scaling. At 4K (8.3 million pixels), the theoretical fill rate would allow roughly 8.2 full-screen passes per frame at 60 FPS, but the measured 4K Medium average of 61 FPS suggests the actual workload is more complex than simple fill-rate calculations. The FP32 throughput of 13.13 TFLOPS is modest by modern standards, which likely contributes to the significant FPS drops when transitioning from 1440p to 4K.

Settings Recommendations

The measured data provides clear guidance for optimal settings. At 1920x1080, the Medium preset delivers 186 FPS average with a minimum of 158 FPS, which is ideal for high-refresh-rate displays. The High preset at 1080p yields 131 FPS, still smooth, while Ultra yields 125 FPS — a marginal 4.6% drop from High. Given the tiny gap between High and Ultra at 1080p, the Ultra preset is the better choice for users wanting maximum visual quality without sacrificing meaningful frame rate.

At 2560x1440, the Medium preset delivers 117 FPS average (100 min, 135 max), which is excellent for 1440p gaming. The High preset yields 83 FPS, and Ultra yields 79 FPS. The 38 FPS gap between Medium and High is substantial, while the 4 FPS gap between High and Ultra is negligible. For 1440p users, the High preset offers the best balance — 83 FPS is above the 60 FPS threshold for smooth gameplay, and the Ultra preset's 79 FPS does not justify any potential visual degradation from settings adjustments. However, users with 60 Hz displays could comfortably choose Ultra at 79 FPS.

At 3840x2160, the Medium preset delivers 61 FPS average (52 min, 70 max), which just meets the 60 FPS standard for most displays. The Low preset yields 86 FPS, providing headroom for 75 Hz or 90 Hz displays. The High preset at 43 FPS and Ultra at 41 FPS are below the 60 FPS threshold and would result in noticeable stutter on standard displays. For 4K users, the Medium preset is the recommended choice — it provides the highest settings while maintaining playable frame rates. The Low preset is preferable if a higher refresh rate is a priority, as it delivers 86 FPS with minimal visual compromise.

The data shows that the Ultra preset offers diminishing returns across all resolutions. At 1080p, Ultra is 6 FPS slower than High; at 1440p, it is 4 FPS slower; at 4K, it is 2 FPS slower. This pattern suggests that the Ultra preset's additional visual effects are not particularly demanding in Pc Building Simulator, but they also do not provide enough of a frame rate penalty to warrant avoiding the preset when FPS is already high.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread Zen 4 processor built on TSMC's 5 nm process. It features a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a 55 W TDP. The CPU's cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. Memory support includes DDR5 with dual-channel configuration and 83.2 GB/s bandwidth. The CPU also includes integrated Radeon 610M graphics and supports PCIe Gen 5 with 28 lanes.

The CPU's benchmark results are exceptional. Its Cinebench R23 multi-core score of 42713 and single-core score of 6030 place it in the 95th percentile versus all CPUs. The PassMark multi-thread score of 51405 and single-thread score of 3907 reinforce its position as a high-end mobile processor. Its average benchmark score of 76212 is nearly identical to the Intel Core Ultra 9 285HX (76155, 0.1% lower) and slightly below the AMD EPYC Embedded 8224P (76492, 0.4% higher) and Threadripper PRO 9945WX (76513, 0.4% higher).

In Pc Building Simulator, the CPU's role is less prominent than the GPU's at higher resolutions, but it becomes more relevant at 1080p. The 1080p Low average of 262 FPS and Medium average of 186 FPS indicate that the CPU can drive very high frame rates when the GPU is not the bottleneck. The 1080p Medium min FPS of 158 suggests that even at 1080p, the CPU rarely struggles to keep up with the GPU's demands.

The CPU's 32 threads and 64 MB of L3 cache are well-suited for a simulation title like Pc Building Simulator, which may involve complex system state calculations and component interactions. The high single-thread performance (6030 in Cinebench R23 single-core) ensures that any single-threaded game logic runs efficiently, while the multi-threaded capability provides headroom for background tasks or multi-threaded game systems.

The CPU's 95th percentile ranking versus the GPU's 75th percentile ranking suggests that in CPU-bound scenarios, the combo could perform significantly better than its overall rank of 2060/3723 indicates. However, the measured data shows that at 4K, the GPU is the clear bottleneck — the CPU's capability is largely idle at that resolution. Users who primarily play at 1080p or 1440p with lower settings will benefit more from the CPU's strength, while 4K users will find the GPU to be the limiting factor.
