FAQ

Q: What is the best resolution for this combo in Overpower?

A: The data shows 2560x1440 as the sweet spot. At Medium settings, it delivers 116 FPS average with a minimum of 99 FPS, while 1920x1080 at the same settings only adds 14 FPS (130 average). The jump to 3840x2160 costs 17 FPS (99 average) at Medium, making 1440p the most balanced choice for maintaining high refresh rates without sacrificing visual quality.

Q: How does the RTX 5080 Mobile compare to its nearest GPU rivals?

A: The GPU's average benchmark score of 38,349 places it 0.6% above the RTX 4080 Mobile (38,135) and 0.1% above the MX570 (38,299), while sitting 0.9% below both the MX570 A and Radeon Pro 580X. Despite the name suggesting a large generational leap, the measured data shows a near-tie with the previous generation's top mobile part.

Q: What is the CPU's standing relative to other processors?

A: The Core Ultra 7 155H scores 32,697 on average, which is statistically identical to the Core i5-14600T (32,707, 0% delta) and the AMD Ryzen AI 7 PRO 360 (32,662, +0.1% delta). It sits 0.2% behind the Ryzen 5 7400F and 0.4% behind the Ryzen 7 PRO 6850H, placing it in the 83rd percentile of all CPUs.

Q: Does this system maintain playable frame rates at 4K Ultra settings?

A: Yes, but barely above the 60 FPS threshold. The measured 3840x2160 Ultra average is 76 FPS, which is 24% lower than the 4K High average of 92 FPS. For competitive play or high-refresh displays, the Low preset at 4K (158 FPS) is the only setting that approaches the 144Hz territory.

Q: How much performance is lost when moving from 1080p to 4K?

A: At Medium settings, the drop from 1920x1080 (130 FPS) to 2560x1440 (116 FPS) is 10.8%, and the further drop to 3840x2160 (99 FPS) is another 14.7% from 1440p. Across all four settings, the 1080p-to-4K penalty averages roughly 40-50% of the original frame rate.

Q: Which API features does the GPU support for this game?

A: The RTX 5080 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Blackwell architecture includes 60 RT cores and 240 tensor cores, though Overpower's measured results do not specifically isolate ray tracing or DLSS performance.

GPU Role

The NVIDIA GeForce RTX 5080 Mobile is built on the GB203 chip using TSMC's 5 nm process, with 45,600 million transistors on a 378 mm² die. Its memory subsystem is substantial: 16 GB of GDDR7 on a 256-bit bus delivers 896.0 GB/s of bandwidth, which is critical for Overpower's asset streaming at high resolutions. The base clock of 975 MHz boosts to 1500 MHz, producing 23.04 TFLOPS of FP32 throughput from 7,680 shading units.

The GPU's 240 texture mapping units and 96 ROPs yield a texture rate of 360.0 GTexel/s and a pixel rate of 144.0 GPixel/s. These figures explain why the combo maintains 92 FPS at 4K High: the raw fill rate is sufficient for the game's particle effects and post-processing at that resolution. However, the jump from High to Ultra at 4K (92 to 76 FPS) suggests that the Ultra preset adds shading complexity that pushes against the GPU's 23.04 TFLOPS ceiling.

The 80 W TDP for the mobile GPU is notably modest for a flagship part, and the "IGP" slot width with no power connectors indicates this is designed for integrated form factors. Despite this power envelope, the GPU's PassMark G3D score of 27,711 places it in the 81st percentile of all GPUs. The Geekbench OpenCL score of 166,986 and Vulkan score of 169,754 show balanced compute and graphics performance, which aligns with the consistent frame rates observed across Overpower's settings presets.

The GPU's nearest rival data reveals an interesting story: the RTX 5080 Mobile's average score of 38,349 is only 0.6% above the RTX 4080 Mobile (38,135). In practical Overpower terms, this means the newer Blackwell part does not deliver a generational leap over its predecessor. The 3DMark Steel Nomad DX12 score of 4,952 provides a synthetic reference point, but the real-world measured FPS shows the GPU is capable of well over 200 FPS at 1080p Low, indicating headroom that heavier settings quickly consume.

How This Combo Ranks

The combo ranks 990th out of 3,713 tested combinations in Overpower, placing it in the top 26.7% of all systems. This rank reflects the balance between the CPU's 83rd percentile standing and the GPU's 81st percentile, suggesting the pairing is well-matched for this title.

The rank is more impressive when considering the component-level competition. The CPU's nearest rival, the Core i5-14600T, has a near-identical average score (32,707 vs 32,697, 0% delta), yet the combo's overall rank depends on how the GPU interacts with Overpower's specific workload. Similarly, the GPU's closest rival, the MX570, scores 38,299 (0.1% lower), but the RTX 5080 Mobile's higher memory bandwidth and larger VRAM pool likely contribute to better sustained performance in this game.

A rank of 990 out of 3,713 means there are 989 combos that achieve higher frame rates in Overpower. Given that the GPU is within 1% of several rivals, the differentiating factor is likely the CPU's 16 cores and 22 threads, which prevent bottlenecking at lower resolutions. The 83rd percentile CPU score and 81st percentile GPU score are close enough that neither component dominates the other, resulting in a balanced system that scales predictably across settings.

Settings Recommendations

At 1920x1080, the Medium preset delivers 130 FPS average with a minimum of 111 FPS and maximum of 150 FPS. This is the best balance of smoothness and visual fidelity, as High only adds 9 FPS (121 average) — actually lower than Medium, which is unusual and suggests the High preset may apply different optimization paths. Ultra drops to 100 FPS, which is still playable but sacrifices 23% of the Medium frame rate for marginal visual gains.

For 2560x1440, Medium again emerges as the optimal choice with 116 FPS average (99 min, 133 max). High delivers 108 FPS, a 6.9% reduction, while Ultra falls to 89 FPS. The Low preset at 186 FPS is only useful for competitive play where frame rate trumps visuals.

At 3840x2160, the recommendation shifts. Medium (99 FPS) and High (92 FPS) are both viable, but Medium's 84 FPS minimum is better suited to maintaining a stable experience. Ultra at 76 FPS is playable but enters the range where frame time consistency becomes more noticeable. Low at 158 FPS is the only 4K preset that fully exploits high refresh rate displays.

The data shows a clear pattern: Medium is the sweet spot at every resolution, with the gap between Medium and High being minimal (2-7 FPS) while the Medium-to-Ultra penalty is substantial (23-30 FPS). For the best experience, start with Medium and adjust individual settings upward only if the frame rate allows.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest raw performance. Low settings produce 208 FPS average, which is the fastest measured result in the entire dataset. Medium drops to 130 FPS (111 min, 150 max), High to 121 FPS, and Ultra to 100 FPS. The 108 FPS spread between Low and Ultra demonstrates the GPU's ability to handle both extremes, but the 30 FPS gap between Medium and Ultra suggests diminishing returns on visual quality investment.

Moving to 2560x1440, the scaling is consistent. Low yields 186 FPS (10.6% below 1080p Low), Medium 116 FPS (10.8% below 1080p Medium), High 108 FPS (10.7% below), and Ultra 89 FPS (11% below). This uniform ~11% reduction across all settings indicates the GPU is the primary bottleneck at 1440p, as the CPU has enough headroom to maintain the same performance ratio.

At 3840x2160, the pattern changes. Low drops to 158 FPS (15.1% below 1440p Low), Medium to 99 FPS (14.7% below), High to 92 FPS (14.8% below), and Ultra to 76 FPS (14.6% below). The slightly larger percentage drop at 4K compared to 1440p (15% vs 11%) reflects the increased pixel count overwhelming the GPU's fill rate, particularly at Ultra where the 76 FPS average approaches the lower bounds of high-refresh gaming.

The Medium presets are the only ones with complete min/max data: 111-150 FPS at 1080p, 99-133 FPS at 1440p, and 84-113 FPS at 4K. These ranges show a consistent 25-30 FPS spread between minimum and maximum, indicating stable frame pacing without severe hitches.

CPU Role

The Intel Core Ultra 7 155H features 16 cores (likely a mix of performance and efficiency cores) with 22 threads, running at a base clock of 3.80 GHz and boosting to 4.80 GHz. This Meteor Lake architecture, built on Intel's 7 nm process, includes 24 MB of shared L3 cache plus 2 MB L2 per core and 112 KB L1 per core. The 28 W TDP is remarkably low for a 16-core part, which explains the 83rd percentile ranking rather than a higher placement.

The CPU's benchmark scores show strong multi-threaded capability: Cinebench R23 multicore at 15,028 and PassMark multithread at 24,873. Single-thread performance is solid with Cinebench R23 single-core at 1,743 and PassMark single-thread at 3,468. These figures suggest the CPU can drive the GPU effectively even at 1080p, where frame rates exceed 200 FPS.

In Overpower, the CPU's role becomes apparent in the scaling pattern. The 1080p-to-1440p drop is consistent at ~11% across all settings, which indicates the CPU is not the limiting factor at these resolutions. However, the 208 FPS at 1080p Low suggests the CPU can sustain very high frame rates when the GPU has minimal work. The 16 cores and 22 threads provide ample parallel processing for game logic and physics, while the 4.80 GHz boost clock handles single-threaded rendering commands.

The CPU's nearest rival comparison is telling: the Core i5-14600T scores 32,707 (0% delta), yet the 155H has a significantly higher TDP ceiling in mobile form. The AMD Ryzen AI 7 PRO 360 at 32,662 (+0.1%) is essentially identical in average score. This means Overpower's performance is not sensitive to the small differences between these mid-range mobile processors — the GPU does the heavy lifting.

Resolution Scaling

The measured data reveals a clear pattern in how Overpower scales across resolutions. From 1920x1080 to 2560x1440, frame rates drop by approximately 11% across all four settings presets. This uniform reduction indicates a GPU-bound scenario where the CPU has sufficient headroom to maintain consistent performance.

From 2560x1440 to 3840x2160, the drop increases to approximately 15% across all settings. This larger percentage reduction at 4K suggests the GPU's pixel throughput capabilities (144.0 GPixel/s) and memory bandwidth (896.0 GB/s) are being taxed more heavily. The 16 GB GDDR7 VRAM is sufficient for 4K textures, but the 256-bit bus width limits the bandwidth available for the increased resolution.

The specific numbers illustrate this: 1080p Medium (130 FPS) to 1440p Medium (116 FPS) is a 14 FPS loss, while 1440p Medium to 4K Medium (99 FPS) is a 17 FPS loss. At Ultra, the progression is 100 → 89 → 76 FPS, with the 4K step costing 13 FPS versus 11 FPS for the 1440p step. The Low preset shows the most dramatic scaling: 208 → 186 → 158 FPS, with the 4K drop (28 FPS) nearly double the 1440p drop (22 FPS).

This scaling behavior identifies the GPU as the primary limiting component at all resolutions. The CPU's 16 cores and 22 threads are more than adequate for Overpower's engine, as evidenced by the consistent percentage drops that would not occur if the CPU were the bottleneck. The RTX 5080 Mobile's 23.04 TFLOPS of FP32 compute is sufficient for 1080p and 1440p gaming, but 4K Ultra (76 FPS) approaches the practical limit of this mobile GPU's capabilities in this title.
