Lockdown Protocol

# Lockdown Protocol: Intel Core Ultra 5 235HX + NVIDIA GeForce RTX 4080

The measured frame rates for this combination reveal a system that is clearly GPU-bound at higher resolutions but capable of exceptional throughput at 1080p. With the RTX 4080's 16 GB of GDDR6X memory and the Core Ultra 5 235HX's 14 cores, the pairing delivers playable performance across all tested settings, though the scaling patterns indicate where each component's contribution peaks.

Resolution Scaling

The data shows a predictable decline in average FPS as resolution increases, but the magnitude of that decline varies significantly by settings preset. At Low settings, the drop from 1920x1080 to 2560x1440 is 64 FPS (239 to 175), and further to 3840x2160 brings another 62 FPS reduction (175 to 113). That represents a 52.7% decrease from 1080p to 4K at Low, suggesting the GPU is still managing heavy lifting even at minimal graphical load.

At High settings, the scaling is steeper: 148 FPS at 1080p falls to 109 FPS at 1440p, then to 70 FPS at 4K. The 4K High result represents only 47.3% of the 1080p High figure, indicating that the RTX 4080's rendering pipeline becomes increasingly stressed as pixel count grows. The gap between Low and High at 4K (113 versus 70 FPS) is 43 FPS, which is substantial but not as wide as the 91 FPS gap observed at 1080p (239 versus 148 FPS).

Ultra settings show the most dramatic resolution sensitivity: 111 FPS at 1080p, 81 FPS at 1440p, and just 53 FPS at 4K. The 4K Ultra result drops 52.3% relative to 1080p Ultra. This pattern suggests that while the Core Ultra 5 235HX can feed frames adequately at lower resolutions, the RTX 4080 becomes the limiting component as resolution and settings increase, with the 4K Ultra figure falling below the 60 FPS threshold often considered minimum for smooth play.

The Medium preset offers the only complete min/max data across all resolutions, providing insight into frame time consistency. At 1080p Medium, the minimum of 144 FPS and maximum of 195 FPS bracket the 170 FPS average tightly. At 1440p Medium, the spread widens (106 to 143 FPS around a 124 FPS average), and at 4K Medium, the range narrows to 68-92 FPS around an 80 FPS average. This tightening at higher resolutions is typical of a GPU-bound scenario where consistent utilization smooths out CPU-induced frame pacing variations.

GPU Role

The NVIDIA GeForce RTX 4080, built on the Ada Lovelace architecture with a 5 nm process, brings 16 GB of GDDR6X memory across a 256-bit bus, yielding 716.8 GB/s of bandwidth. The GPU's boost clock of 2505 MHz and base clock of 2205 MHz support its 48.74 TFLOPS FP32 throughput. In the context of Lockdown Protocol, these specifications translate directly to the measured results: the 16 GB frame buffer prevents capacity-related stutters at 4K even with Ultra settings, while the memory bandwidth sustains texture streaming at high resolutions.

The GPU's benchmark profile reinforces its positioning. With a PassMark G3D score of 34457 and a percentile ranking of 86 among all GPUs, the RTX 4080 sits near the top of the performance hierarchy. Its nearest rival, the RTX 4080 SUPER, scores 54209 in average benchmark terms, a mere 0.1% delta, while the AMD Radeon Pro W5700X trails by 1.1% and the RX 6750 GRE 12 GB by 2.6%. These margins are negligible in real-world gaming, meaning the RTX 4080's Lockdown Protocol results likely reflect near-flagship capability.

At 4K Ultra, the 53 FPS average suggests the GPU is the primary constraint. The 3DMark Steel Nomad DX12 score of 6567 indicates strong raw performance, but Lockdown Protocol's demands at 4K Ultra exceed what even this GPU can sustain at 60 FPS. Conversely, the 239 FPS at 1080p Low shows the GPU has ample headroom when pixel count and effects are reduced. The RTX 4080's 76 RT cores and 304 tensor cores are present in the hardware, though the measured data does not isolate ray tracing or DLSS effects specifically.

CPU Role

The Intel Core Ultra 5 235HX, part of the Arrow Lake-HX family, provides 14 cores and 14 threads with a base clock of 2.90 GHz and boost clock of 5.10 GHz. This mobile processor, fabricated on TSMC's 3 nm node with 17,800 million transistors, delivers strong multi-threaded performance as evidenced by its Cinebench R23 multi-core score of 34731 and PassMark multi-thread score of 40849. The 24 MB shared L3 cache and 102.4 GB/s memory bandwidth are sufficient for feeding the RTX 4080 in most scenarios.

The CPU's percentile ranking of 91 among all processors places it in elite company. Its nearest rivals include the AMD EPYC 8124P (delta -0.1%), Ryzen 9 5950X (delta +0.2%), Core i7-14700 (delta -0.4%), and Core i9-13900F (delta +0.7%). These sub-1% deltas mean the 235HX trades blows with desktop-class parts from previous generations, which is remarkable for a mobile chip. In Lockdown Protocol, this translates to sufficient single-thread performance (Cinebench R23 single-core score of 4903) to avoid bottlenecking the GPU at lower resolutions.

The evidence of CPU adequacy appears in the 1080p results. At Low settings, the 239 FPS average indicates the CPU can issue draw calls and physics updates quickly enough to keep the GPU busy. Even at Ultra settings, 111 FPS at 1080p suggests the CPU is not the limiting factor; if it were, we would observe similar FPS across resolutions for a given preset. Instead, the monotonic decline from 1080p to 4K across all presets is the signature of GPU-bound performance. The 14-core configuration may be underutilized in this FPS title, but its high boost clock ensures responsive frame delivery.

FAQ

Q: Why does 4K Ultra produce only 53 FPS when the GPU is so powerful?

A: The RTX 4080's 16 GB frame buffer and 48.74 TFLOPS are substantial, but Lockdown Protocol at 3840x2160 with Ultra settings demands more than the GPU can deliver at 60 FPS. The measured 53 FPS average reflects the GPU's absolute limit at this configuration, with no indication of CPU-related stalling.

Q: Is the Core Ultra 5 235HX sufficient for this game?

A: Yes. The CPU's Cinebench R23 multi-core score of 34731 and single-core score of 4903 place it in the 91st percentile among all processors. The data shows FPS scaling consistently with resolution, which would not occur if the CPU were a bottleneck.

Q: How does the RTX 4080 compare to its closest rival in benchmark scores?

A: The RTX 4080's average benchmark score of 54247 is nearly identical to the RTX 4080 SUPER's 54209, a delta of just 0.1%. The AMD Radeon Pro W5700X trails by 1.1%, and the RX 6750 GRE 12 GB by 2.6%.

Q: What is the best resolution for competitive play?

A: At 1920x1080, even Ultra settings deliver 111 FPS, while Low reaches 239 FPS. For maximum responsiveness, 1080p Low offers the highest frame rate, but 1440p High at 109 FPS provides a balance of visual quality and speed.

Q: Does the Medium preset show consistent frame times?

A: The measured min/max values for Medium settings are 144-195 FPS at 1080p, 106-143 FPS at 1440p, and 68-92 FPS at 4K. These ranges indicate moderate frame pacing variance, with the 4K result showing the tightest relative consistency.

Q: How does the CPU's 14-thread configuration affect gaming performance?

A: Lockdown Protocol, as an FPS title, likely uses fewer threads. The 235HX's PassMark single-thread score of 4683 and Cinebench R23 single-core score of 4903 indicate strong per-core performance, which matters more than raw thread count for this genre.

Measured FPS Breakdown

At 1920x1080, the Low preset yields an average of 239 FPS, the highest recorded for this combination. Medium settings produce 170 FPS with a minimum of 144 and maximum of 195. High settings achieve 148 FPS, while Ultra drops to 111 FPS. The spread from Low to Ultra is 128 FPS, demonstrating that settings have a profound impact at this resolution.

Moving to 2560x1440, Low averages 175 FPS, Medium averages 124 FPS (min 106, max 143), High averages 109 FPS, and Ultra averages 81 FPS. The delta between Low and Ultra narrows to 94 FPS, reflecting increased GPU workload at higher pixel counts. The 1440p Medium result of 124 FPS remains well above the 60 FPS threshold, making this a viable high-refresh-rate option.

At 3840x2160, Low is the only preset exceeding 100 FPS, averaging 113 FPS. Medium averages 80 FPS (min 68, max 92), High averages 70 FPS, and Ultra falls to 53 FPS. The Low-to-Ultra gap shrinks further to 60 FPS, indicating that the GPU is nearing its ceiling regardless of settings. The 4K Ultra result of 53 FPS is the only measured configuration below 60 FPS average, and even 4K High at 70 FPS leaves limited headroom for demanding scenes.

Settings Recommendations

For players prioritizing frame rate above all else, the 1920x1080 Low preset at 239 FPS is the clear choice. This configuration maximizes the RTX 4080's throughput and is suitable for competitive play where every millisecond matters. However, the 170 FPS at 1080p Medium offers a substantial visual upgrade for a 69 FPS sacrifice, which may be a worthwhile trade-off for most users.

At 1440p, the Medium preset at 124 FPS strikes an excellent balance. The minimum of 106 FPS ensures smooth gameplay even during intense moments, while the 143 FPS maximum indicates the GPU can burst well above the average. High settings at 109 FPS are also viable, but the 15 FPS difference between Medium and High does not justify the potential visual gains for competitive players.

For 4K, the Low preset at 113 FPS is the only configuration that provides a comfortable margin above 60 FPS. Medium at 80 FPS is playable but leaves less headroom, and High at 70 FPS approaches the threshold where frame drops become noticeable. Ultra at 53 FPS falls below the 60 FPS target and is not recommended for smooth gameplay. The data suggests that 4K users should either accept Low settings for high refresh rates or Medium for a balance of quality and performance.

How This Combo Ranks

Among the 2828 tested combinations in Lockdown Protocol, this pairing of Intel Core Ultra 5 235HX and NVIDIA GeForce RTX 4080 achieves rank 867. This places it in the top 30.7% of all configurations tested, which is respectable but not exceptional for a system featuring a GPU that ranks in the 86th percentile among all GPUs. The gap between the GPU's percentile and the combo's rank suggests that other factors, such as CPU selection or memory configuration, may be limiting the overall performance ceiling.

The RTX 4080's nearest rival, the RTX 4080 SUPER, shows a 0.1% benchmark delta, meaning combos using that GPU would rank nearly identically. The CPU's position relative to rivals like the Ryzen 9 5950X (0.2% delta) and Core i9-13900F (0.7% delta) further explains why this combo does not crack the top 500. In Lockdown Protocol, where the data shows clear GPU-bound behavior at higher resolutions, the CPU's contribution to the final rank is secondary. Still, a rank of 867 out of 2828 indicates that most tested systems with similar GPUs achieve comparable or better frame rates, possibly through higher-clocked desktop processors or more aggressive power delivery.
