Red Dead Redemption 2

# CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F is a 6-core, 12-thread desktop processor built on the Zen 4 architecture (codename Phoenix) using TSMC's 4 nm process node. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU features a 16 MB shared L3 cache, 1 MB L2 per core, and 64 KB L1 per core, and it supports dual-channel DDR5 memory with a bandwidth of 83.2 GB/s. This processor sits in the 77th percentile versus all CPUs in the database, with an average benchmark score of 25,005.

In single-threaded performance, the 8400F scores 951 in 3dmark_single_thread and 2,943 in Cinebench R23 single-core. Its multi-threaded capability is more substantial: 6,091 in 3dmark_16_threads, 6,165 in 3dmark_max_threads, and 20,851 in Cinebench R23 multicore. These scores indicate a balanced processor that can handle both lightly-threaded game logic and more demanding background tasks, though in a game like Red Dead Redemption 2, the 6-core/12-thread configuration is sufficient to avoid becoming the primary bottleneck at lower resolutions.

The CPU's closest rivals in the database are the AMD Ryzen 5 7500F (average score 24,964, deltaPct 0.2% higher), Intel Core i7-11850H (24,935, deltaPct 0.3% higher), and Intel Core i7-13620H (24,911, deltaPct 0.4% higher). The 8400F trails the AMD EPYC 9474F by 0.4% (that CPU scores 25,103). These margins are extremely tight, meaning the 8400F performs essentially on par with its immediate competition in synthetic benchmarks. For Red Dead Redemption 2, this means the CPU is capable of feeding frames to the GPU without introducing major frame pacing issues, but as the measured FPS data will show, the GPU becomes the limiting factor long before CPU headroom is exhausted.

# GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B370 is an integrated GPU based on the Xe3-LPG architecture (chip: Panther Lake) fabricated on Intel's 3 nm process node. It operates at a base clock of 300 MHz with a boost clock of 2,400 MHz, and importantly, it uses System Shared memory — meaning there is no dedicated VRAM, and memory bandwidth is system dependent. The GPU has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores, delivering a pixel rate of 48.00 GPixel/s, a texture rate of 96.00 GTexel/s, and 6.144 TFLOPS of FP32 compute. The TDP is rated at 25 W, and it is an IGP (integrated graphics processor) with no power connectors required.

This GPU sits in the 5th percentile versus all GPUs in the database, with an average benchmark score of 1,184 from the 3dmark_steel_nomad_dx12 test. Its nearest rivals are the ATI Mobility Radeon HD 5570 (score 1,186, deltaPct -0.2% lower), ATI Radeon HD 5770 (1,190, deltaPct -0.5% lower), AMD Radeon HD 7650M (1,192, deltaPct -0.7% lower), and AMD FirePro M2000 (1,168, deltaPct 1.4% higher). The Arc B370's performance is therefore comparable to that of legacy desktop GPUs from over a decade ago, which sets expectations for its ability to run a demanding open-world title like Red Dead Redemption 2.

The absence of dedicated VRAM is a critical factor. With System Shared memory, the GPU must compete with the CPU for memory bandwidth, and in a game with large textures like Red Dead Redemption 2, this can lead to severe performance degradation, especially at higher resolutions. The measured FPS data confirms this: at 4K Ultra, the average drops to 10 FPS, which is barely playable even for a turn-based strategy, let alone an action-adventure title. The GPU's low percentile ranking (5th) and its proximity to ancient discrete cards in benchmark scores underscore that this iGPU is not designed for modern gaming at playable frame rates.

# Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals a clear pattern of GPU-bound scaling. At 1080p Low, the combo achieves 47 FPS average. Moving to 1440p Low, the average drops to 35 FPS, a 25.5% reduction. At 4K Low, the average falls to 23 FPS, a further 34.3% drop from 1440p. This steep decline as resolution increases is textbook GPU-bound behavior — the CPU is not the limiting factor because the absolute frame rates are already low enough that the CPU can easily keep up.

For Medium settings, the scaling is similarly steep: 1080p Medium averages 35 FPS, 1440p Medium averages 26 FPS (a 25.7% drop), and 4K Medium averages 17 FPS (a 34.6% drop from 1440p). At High settings, the pattern continues: 29 FPS at 1080p, 22 FPS at 1440p (24.1% drop), and 14 FPS at 4K (36.4% drop). Ultra settings show the most drastic scaling: 21 FPS at 1080p, 16 FPS at 1440p (23.8% drop), and 10 FPS at 4K (37.5% drop).

The consistency of these percentage drops across all settings presets indicates that the GPU's rasterization and memory bandwidth constraints dominate. If the CPU were the bottleneck, we would expect to see smaller FPS differences between 1080p and 4K at lower settings (where the GPU has less work per pixel). Instead, the FPS halves or worse when quadrupling pixel count, which is exactly what happens when a GPU is saturated. The Arc B370's System Shared memory also contributes to this scaling, as higher resolutions require more memory traffic, further stressing the shared bandwidth.

# Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo produces the following average FPS by settings preset: Low averages 47 FPS, Medium averages 35 FPS (with a min of 30 and max of 40), High averages 29 FPS, and Ultra averages 21 FPS. The delta from Low to Ultra is 26 FPS, a 55.3% reduction. The Medium preset's min/max range of 30 to 40 FPS indicates some frame variance, but the average remains consistent.

Moving to 2560x1440, the averages are: Low at 35 FPS, Medium at 26 FPS (min 22, max 30), High at 22 FPS, and Ultra at 16 FPS. The drop from 1080p Low (47 FPS) to 1440p Low (35 FPS) is 12 FPS, and from 1080p Ultra (21 FPS) to 1440p Ultra (16 FPS) is 5 FPS. The absolute FPS values at 1440p are already below the threshold for smooth gameplay in an action title, with even Low settings failing to reach 40 FPS.

At 3840x2160, the results are severely constrained: Low averages 23 FPS, Medium averages 17 FPS (min 15, max 20), High averages 14 FPS, and Ultra averages 10 FPS. The gap between Low and Ultra at 4K is only 13 FPS, suggesting that at this resolution the GPU is so overwhelmed that even reducing settings yields diminishing returns. The 4K Medium preset's min of 15 FPS and max of 20 FPS highlight tight frame times, but at a level that is unplayable for a game requiring quick reactions.

Across all resolutions, the Low preset offers the highest FPS, but even at 1080p, 47 FPS is only marginally above the 30 FPS console-like baseline. The data shows that this combo is best suited for 1080p with Low settings if any semblance of playability is desired, and higher resolutions or settings presets push the frame rate into single digits or low twenties.

# How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations for Red Dead Redemption 2, this specific combo (AMD Ryzen 5 8400F + Intel Arc B370) ranks 3,430 out of 3,714 total combos. This places it in the bottom 7.6% of all tested configurations, which is consistent with the GPU's 5th percentile ranking among all GPUs. The CPU, by contrast, ranks in the 77th percentile, so the disparity between CPU and GPU capability is stark.

The rank of 3,430 means that 284 other combos perform worse, but the vast majority of tested systems (3,429) outperform this pairing. This is not surprising given that the Arc B370 is an integrated GPU with performance comparable to decade-old discrete cards like the ATI Radeon HD 5770. The CPU's nearest rivals (Ryzen 5 7500F, Core i7-11850H, etc.) would likely achieve much higher rankings when paired with a discrete GPU, but in this combo, the GPU drags the overall result down.

The combo's rank is particularly low for a modern system featuring a 2024-released CPU and a 2026-released GPU. The 8400F's strong multi-threaded scores (20,851 in Cinebench R23 multicore) are irrelevant when the GPU cannot render frames fast enough. In relative terms, this combo ranks in the bottom decile, meaning users would need to accept very low settings and resolutions to get playable frame rates, and even then, the experience would be marginal.

# Settings Recommendations — which preset gives the best experience per the measured rows

Based solely on the measured FPS data, the only settings preset that approaches a playable experience is 1080p Low, which averages 47 FPS. This is the highest average FPS recorded for this combo across any resolution or settings combination. At 1080p Medium, the average drops to 35 FPS, which is still borderline playable for a slower-paced game, but for an action-adventure title like Red Dead Redemption 2 with shooting mechanics, 35 FPS is likely to feel less responsive.

At 1440p, even Low settings (35 FPS average) fail to provide a comfortable margin above 30 FPS, and the min FPS data for Medium (22 FPS) suggests that dips below 30 FPS are common. At 4K, no preset achieves even 30 FPS average; the best is Low at 23 FPS, and Ultra drops to 10 FPS, which is unplayable for any genre.

Therefore, the recommendation from the data is clear: run the game at 1080p with Low settings to maximize average frame rate. If visual quality is a priority over frame rate, 1080p Medium at 35 FPS is the next best option, but the user should be aware that the min FPS of 30 is at the edge of acceptability. At 1440p, Low settings are the only viable option, and at 4K, the combo is not suitable for gameplay. The data suggests that the Arc B370's System Shared memory and low compute throughput (6.144 TFLOPS) cannot handle the demands of Red Dead Redemption 2 at higher resolutions.
