High On Life

High On Life pairs one of Intel’s older 11th-generation desktop processors, the Core i5-11400F, with NVIDIA’s top-tier Ada Lovelace GPU, the GeForce RTX 4080. This combination produces a wide spread of frame rates depending on resolution and settings, and the measured data reveals how the CPU and GPU trade off responsibility as pixel count climbs. The RTX 4080 is clearly the dominant component in most scenarios, but the six-core Rocket Lake chip still shapes the upper bounds at lower resolutions.

Resolution Scaling

The frame rate deltas between 1080p, 1440p, and 4K are substantial, and they tell a clear story about where the bottleneck sits. At 1080p with High settings, the combo averages 171 FPS. Moving to 1440p High drops that to 133 FPS, a reduction of 38 FPS or roughly 22% lower. Jumping to 4K High yields 81 FPS, which is 52 FPS below the 1440p result and 90 FPS below the 1080p result. The scaling from 1440p to 4K is steeper in percentage terms (about 39% lower) than the 1080p-to-1440p step, which suggests the GPU is becoming increasingly saturated as resolution rises.

Low settings show a similar pattern but with higher absolute numbers. At 1080p Low, the system hits 200 FPS. At 1440p Low, it falls to 177 FPS, a 23 FPS drop. At 4K Low, the average is 125 FPS, which is 52 FPS below the 1440p figure. The gap between 1080p and 1440p Low (23 FPS) is smaller than the gap between 1440p and 4K Low (52 FPS), indicating that the RTX 4080 still has headroom at 1440p but starts to feel the pixel load at 4K.

The Medium preset shows the most complete data, with min and max FPS recorded. At 1080p Medium, the average is 183 FPS, with a minimum of 155 FPS and a maximum of 210 FPS. At 1440p Medium, the average drops to 160 FPS, with min and max at 136 FPS and 185 FPS respectively. At 4K Medium, the average falls to 98 FPS, with a minimum of 83 FPS and a maximum of 112 FPS. The min-to-max spread narrows as resolution increases, which is typical: at 4K, the GPU is working closer to its limit, so frame time variance shrinks.

Ultra settings amplify the resolution scaling. At 1080p Ultra, the average is 141 FPS. At 1440p Ultra, it drops to 99 FPS. At 4K Ultra, the average is 60 FPS. The 1440p-to-4K drop here is 39 FPS, which is the largest absolute reduction across any settings tier. This indicates that Ultra at 4K pushes the RTX 4080 to its limits in this game, while the CPU still manages to keep up at 1080p Ultra.

The overall pattern suggests that at 1080p, the Core i5-11400F is the more significant constraint, as the GPU is capable of far higher frame rates than the CPU can feed. At 4K, the RTX 4080 becomes the limiting factor, and the CPU’s role diminishes. The 1440p results sit in a balanced zone where both components contribute meaningfully to performance.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, built on Intel’s 14 nm process. Its base clock is 2.60 GHz, and it boosts to 4.40 GHz. The CPU has 80 KB of L1 cache per core, 512 KB of L2 cache per core, and 12 MB of shared L3 cache. It supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s.

In synthetic benchmarks, the chip scores 5,619 in 3DMark’s 16-thread test and 868 in the single-thread test. Cinebench R23 results show 14,340 multi-core and 2,024 single-core. These numbers place the CPU in the 71st percentile among all tested processors, with an average benchmark score of 17,177. Its nearest rivals include the AMD EPYC 7H12 (0.3% higher score), Intel Core i5-12450H (0.4% lower), AMD Ryzen 3 PRO 8300G (0.6% lower), and Intel Core Ultra 7 164U (0.6% higher).

For High On Life, the CPU’s impact is most visible in the 1080p results. At 1080p Low, the system hits 200 FPS, which is likely near the practical ceiling for this processor in this game. The delta between 1080p Low and 1440p Low is only 23 FPS, whereas the delta between 1440p Low and 4K Low is 52 FPS. This suggests that at 1080p, the GPU is waiting on the CPU more often, and reducing settings does not yield the full frame rate increase a more powerful CPU might allow.

At 4K, the CPU role diminishes. The 4K High result of 81 FPS and 4K Ultra result of 60 FPS are both far below what the CPU could theoretically support, indicating the RTX 4080 is the primary driver. The 4K Low result of 125 FPS is still well within the CPU’s capability, but the GPU is the one doing the heavy lifting.

The six cores and 12 threads are adequate for this title. The game does not appear to be heavily multi-threaded, as the 3DMark 16-thread score (5,619) is only slightly higher than the 8-thread score (4,691) and the max-thread score (5,652). This means the CPU’s single-thread performance, which is moderate for its generation, is the more relevant factor. The single-thread 3DMark score of 868 and Cinebench R23 single-core score of 2,024 are respectable but not exceptional, which helps explain why 1080p frame rates plateau around 200 FPS.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with the AD103 chip, manufactured on TSMC’s 5 nm process. It packs 45,900 million transistors on a 379 mm² die. The GPU has 9,728 shading units, 304 texture mapping units, and 112 ROPs, along with 76 ray tracing cores and 304 tensor cores. Its base clock is 2205 MHz, boosting to 2505 MHz, with memory running at 1400 MHz (22.4 Gbps effective).

The memory subsystem consists of 16 GB of GDDR6X on a 256-bit bus, providing 716.8 GB/s of bandwidth. The GPU’s compute capabilities are substantial: 48.74 TFLOPS of FP32 performance, a pixel rate of 280.6 GPixel/s, and a texture rate of 761.5 GTexel/s. The card has a TDP of 320 W and requires a 700 W power supply. It measures 310 mm in length, 140 mm in height, and 61 mm in width, taking up a triple-slot design.

In synthetic tests, the RTX 4080 scores 6,567 in 3DMark Steel Nomad DX12, 214,739 in Geekbench OpenCL, and 263,779 in Geekbench Vulkan. Its Passmark G3D score is 34,457, with a GPU compute score of 20,671. The GPU sits in the 86th percentile among all tested GPUs, with an average benchmark score of 54,247. Its nearest rivals are the RTX 4080 SUPER (0.1% higher), AMD Radeon Pro W5700X (1.1% lower), AMD Radeon RX 6750 GRE 12 GB (2.6% lower), and AMD Radeon 8060S (2.7% lower).

For High On Life, the GPU’s role is most pronounced at 4K. The 4K Ultra result of 60 FPS is exactly half the 1080p Ultra result of 141 FPS, showing how much the 4K pixel count taxes the GPU. The 4K Medium result of 98 FPS and 4K High result of 81 FPS demonstrate that even with reduced settings, the GPU is the limiting factor at this resolution. The 16 GB of VRAM is more than sufficient for this game, as the measured frames do not indicate any memory-related stutters or crashes.

At 1440p, the GPU still dominates. The 1440p Ultra result of 99 FPS is respectable, while 1440p High hits 133 FPS. The RTX 4080’s raw throughput is clearly enough to push this game well past 60 FPS at 1440p on any preset. The GPU’s high texture rate and pixel rate help maintain consistent frame delivery, as evidenced by the min FPS values at Medium settings: 155 FPS at 1080p, 136 FPS at 1440p, and 83 FPS at 4K.

How This Combo Ranks

This specific pairing of the Core i5-11400F and RTX 4080 ranks 506th out of 3,718 tested combinations for High On Life. That places it in the top 14% of all combos, which is strong given that the CPU is a mid-range part from 2021. The rank reflects the GPU’s high percentile (86th among all GPUs) offset by the CPU’s more modest standing (71st among all CPUs).

The combination’s rank is likely driven by the GPU’s ability to maintain high frame rates at 1440p and 4K, where the CPU’s limitations are less exposed. At 1080p, the combo would rank lower in a CPU-heavy game, but High On Life’s moderate CPU demands allow the RTX 4080 to shine. The 506th rank out of 3,718 is a solid result, placing this setup ahead of the majority of tested systems.

The GPU’s nearest rivals in synthetic scores (RTX 4080 SUPER at 0.1% higher, Radeon Pro W5700X at 1.1% lower) suggest that the combo’s performance is close to what a slightly faster GPU would deliver. The CPU’s rivals (EPYC 7H12 at 0.3% higher, Core Ultra 7 164U at 0.6% higher) are within a narrow band, meaning the 11400F is not a significant outlier in either direction.

Measured FPS Breakdown

The measured data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings tiers (Low, Medium, High, Ultra). At 1080p, the Low preset averages 200 FPS, Medium averages 183 FPS (min 155, max 210), High averages 171 FPS, and Ultra averages 141 FPS. The spread from Low to Ultra is 59 FPS, which is the largest gap across all resolutions, indicating that settings have a significant impact at this resolution.

At 1440p, Low averages 177 FPS, Medium averages 160 FPS (min 136, max 185), High averages 133 FPS, and Ultra averages 99 FPS. The spread from Low to Ultra is 78 FPS, wider than at 1080p, showing that higher settings cost more frame rate as resolution increases. The Medium preset’s min FPS of 136 is still well above 60 FPS, so even the lowest frames are smooth.

At 4K, Low averages 125 FPS, Medium averages 98 FPS (min 83, max 112), High averages 81 FPS, and Ultra averages 60 FPS. The spread from Low to Ultra is 65 FPS, narrower than at 1440p. The Ultra preset’s 60 FPS average is exactly at the common 60 Hz refresh rate threshold, making it playable but not headroom-rich. The Medium preset’s min FPS of 83 indicates that frame drops are not severe.

Comparing settings across resolutions, the Low preset at 4K (125 FPS) is faster than the High preset at 1080p (171 FPS) is slower than Low at 1080p (200 FPS). The Medium preset at 1440p (160 FPS) offers a balanced point, with a min FPS of 136 that is higher than the High preset’s average at 4K (81 FPS). The data shows that the RTX 4080 can deliver 60+ FPS at 4K on Ultra, but dropping to Medium provides a 38 FPS improvement (from 60 to 98 FPS).

Settings Recommendations

For users targeting 60 FPS or higher, the Ultra preset at 4K achieves exactly 60 FPS on average, making it a viable option for 60 Hz displays. However, the Medium preset at 4K delivers 98 FPS, a 63% improvement over Ultra, with a minimum frame rate of 83 FPS that ensures smoother frame pacing. Given that the min FPS at 4K Medium (83) is higher than the average at 4K Ultra (60), the Medium preset is the better choice for consistent performance at 4K.

At 1440p, the Ultra preset averages 99 FPS, which is excellent for high-refresh monitors. The High preset at 133 FPS offers even more headroom, with only a modest visual quality reduction. The Medium preset at 160 FPS is the best option for users with 144 Hz or 165 Hz displays, as its min FPS of 136 stays above the refresh rate threshold. The Low preset at 177 FPS is unnecessary for most users, as the visual trade-off is not worth the extra 17 FPS over Medium.

At 1080p, all presets exceed 140 FPS, so the choice depends on display refresh rate and visual preferences. The Ultra preset at 141 FPS is suitable for 144 Hz monitors, while the High preset at 171 FPS provides more margin. The Medium preset at 183 FPS (min 155) is the sweet spot for 165 Hz displays, as it keeps the minimum above the refresh rate. The Low preset at 200 FPS is only relevant for 240 Hz panels, where every frame matters.

The most balanced experience across all resolutions is the Medium preset. It delivers 183 FPS at 1080p, 160 FPS at 1440p, and 98 FPS at 4K, with minimum frame rates of 155, 136, and 83 respectively. This preset provides the best combination of high averages and stable minimums, making it the recommended starting point for this CPU-GPU combo. For users prioritizing visual fidelity over frame rate, the High preset at 4K (81 FPS) is a reasonable compromise, but the Medium preset’s 17 FPS advantage at 4K (98 vs 81) is more impactful than the visual difference between Medium and High in most scenes.
