Red Dead Redemption 2

# Red Dead Redemption 2 GPU/CPU Scaling Analysis

The AMD Ryzen 9 5950X paired with the Intel Arc B390 produces a severely GPU-bound experience in Red Dead Redemption 2, with the integrated graphics solution acting as the overwhelming performance bottleneck across every resolution and settings preset. The measured data reveals a system that struggles to maintain playable frame rates, with the best-case scenario reaching only 51 FPS at 1080p Low settings, while 4K Ultra drops to a slideshow-level 11 FPS. This combination ranks 2568th out of 2902 tested combos, placing it in the bottom 12% of all configurations, which aligns with the Arc B390's 9th percentile standing among all GPUs and the Ryzen 9 5950X's 91st percentile among all CPUs.

Resolution Scaling

The frame rate penalties from 1080p to 4K are steep and consistent across all settings presets, confirming that the Intel Arc B390's rendering throughput collapses as pixel count rises. At Low settings, the system delivers 51 FPS at 1920x1080 but drops to 38 FPS at 2560x1440 — a 25.5% reduction — and then falls further to 25 FPS at 3840x2160, representing a 51% loss from the 1080p baseline. This scaling pattern indicates that the GPU's fill rate and shader processing capabilities are saturated even at modest resolutions.

The High preset shows similar degradation: 32 FPS at 1080p, 24 FPS at 1440p (a 25% drop), and 16 FPS at 4K (a 50% drop from 1080p). Medium settings follow the same trajectory with 39, 29, and 19 FPS across the three resolutions, while Ultra settings produce 23, 17, and 11 FPS respectively. The consistent ~25% penalty from 1080p to 1440p and ~50% penalty from 1080p to 4K across all presets is a textbook sign of a pixel-throughput-limited GPU, not a CPU-limited scenario.

The 4K to 1440p differential is particularly telling. At Medium settings, the drop from 29 FPS at 1440p to 19 FPS at 4K is a 34.5% reduction, while the 1440p to 1080p step only costs 10 FPS (34.5% again). These proportional losses indicate that the Arc B390's 24 ROPs and 48 TMUs are the limiting factors — doubling pixel count roughly halves performance, which is exactly what the data shows. The measured min/max values at Medium (16-22 FPS at 4K, 24-33 FPS at 1440p, 33-44 FPS at 1080p) also reveal tight frame time consistency, suggesting the GPU is running at its maximum sustainable throughput without thermal or power throttling issues.

Since the Ryzen 9 5950X is a 16-core, 32-thread powerhouse with a 4.90 GHz boost clock, it is not remotely stressed by this workload. The data indicates that even a modestly capable discrete GPU would dramatically improve these numbers, as the CPU has ample headroom to feed far more frames than the Arc B390 can produce.

CPU Role

The AMD Ryzen 9 5950X brings formidable processing resources to this pairing, but its capabilities are almost entirely untapped in Red Dead Redemption 2 at these settings. With 16 cores and 32 threads based on the Zen 3 architecture, the CPU posts a Cinebench R23 multi-core score of 26,017 and a single-core score of 1,614, placing it in the 91st percentile of all CPUs. Its 3.40 GHz base clock and 4.90 GHz boost clock provide strong single-thread performance, which is what most game engines prioritize.

The benchmark data for the Ryzen 9 5950X shows balanced scaling across thread counts: 3DMark scores range from 944 in single-thread to 10,810 in 16-thread tests, with 8-thread performance at 6,598. This indicates that the CPU maintains efficiency as more threads are utilized, which is typical of the Zen 3 architecture's 64 MB L3 cache design. PassMark multi-thread results (45,424) and integer math scores (185,520) further reinforce the CPU's computational strength.

However, in this game and configuration, the CPU's role is essentially reduced to idling. The fact that frame rates at 1080p Low (51 FPS) are only 2.2x higher than 4K Ultra (11 FPS) — despite the massive resolution difference — proves that the GPU is the sole limiting component. If the CPU were a bottleneck, we would expect to see frame rates plateau at higher resolutions, but instead they plummet, which is the signature of a GPU-constrained system.

The Ryzen 9 5950X's nearest rivals in overall CPU benchmarks include the Intel Core Ultra 5 235HX (0.2% faster), AMD EPYC 8124P (0.3% faster), Intel Core i9-13900F (0.4% slower), and Intel Core i7-14700 (0.7% faster). These minuscule deltas — all within 1% — demonstrate that the 5950X remains highly competitive in synthetic workloads, but such differences are irrelevant when the GPU delivers only 11-51 FPS. The CPU could easily power a 200+ FPS experience in this title with a proper discrete GPU, but the Arc B390's output caps everything.

GPU Role

The Intel Arc B390 is the determining factor in this system's performance, and the data paints a grim picture for gaming. This integrated graphics solution based on the Xe3-LPG architecture (Panther Lake chip) has 1,536 shading units, 48 TMUs, and just 24 ROPs, with a boost clock of 2,500 MHz. Its 7.680 TFLOPS FP32 throughput and 60.00 GPixel/s pixel rate are modest numbers, but the critical limitation is its memory configuration: the GPU uses "System Shared" memory with system-dependent bandwidth, meaning it relies on the CPU's DDR4 memory rather than dedicated VRAM.

The Arc B390's benchmark results are catastrophic for gaming. Its 3DMark Steel Nomad DX12 score is just 1,482, placing it in the 9th percentile of all GPUs. The nearest rivals in its benchmark class are the NVIDIA GeForce GT 520MX (1.3% faster), GeForce 800M (1.5% faster), GT 625 OEM (2.5% faster), and GT 710 (2.7% faster) — all ancient entry-level parts. This context explains the measured FPS numbers perfectly: the GPU is competing with hardware from over a decade ago.

In actual game testing, the Arc B390's weaknesses are exposed. At 1080p Low, it manages 51 FPS, which is technically playable but far from smooth. The jump to Medium settings costs 12 FPS (down to 39), High drops to 32 FPS, and Ultra falls to 23 FPS. These settings penalties are substantial — going from Low to Ultra at 1080p costs 28 FPS, a 55% reduction. The same pattern holds at 1440p (38 to 17 FPS, a 55% drop) and 4K (25 to 11 FPS, a 56% drop), showing that the GPU's shading and texture units are equally overwhelmed by higher quality presets.

The memory bandwidth limitation is likely the root cause of the poor scaling. With system-shared memory and system-dependent bandwidth, the Arc B390 competes with the CPU for DDR4 bandwidth (51.2 GB/s for the Ryzen 9 5950X's dual-channel configuration). This creates a bottleneck that prevents the GPU from feeding its 1,536 shaders efficiently, even at low resolutions. The result is that the GPU's theoretical 7.680 TFLOPS is never fully utilized in practice.

The 80W TDP and IGP form factor (slot width "IGP", no power connectors) confirm this is an integrated solution not designed for gaming. Its 60.00 GPixel/s pixel rate — derived from 24 ROPs at 2,500 MHz — is simply insufficient for modern titles at 1080p, let alone higher resolutions. The 120.0 GTexel/s texture rate from 48 TMUs further limits detail rendering, which explains why High and Ultra presets cause such significant frame drops.

FAQ

Q: What is the best resolution for this system?

A: 1080p is the only resolution where the system approaches playability, achieving 51 FPS at Low settings. At 1440p, the best result is 38 FPS (Low), and at 4K, frame rates drop to 25 FPS (Low) or below.

Q: How does the Intel Arc B390 compare to its closest GPU rivals?

A: The Arc B390's 3DMark Steel Nomad score of 1,482 places it 1.3% behind the NVIDIA GeForce GT 520MX, 1.5% behind the GeForce 800M, 2.5% behind the GT 625 OEM, and 2.7% behind the GT 710. All rivals are within 3% of its performance.

Q: Is the Ryzen 9 5950X being fully utilized?

A: No. The CPU is in the 91st percentile of all CPUs with a Cinebench R23 multi-core score of 26,017, while the GPU is in the 9th percentile. The massive performance gap means the CPU has significant unused headroom in this game.

Q: What settings preset provides the smoothest experience?

A: The Low preset at 1080p provides the highest average FPS at 51. Medium at 1080p (39 FPS) is the next best option, followed by High at 1080p (32 FPS). Ultra presets should be avoided entirely, with the best Ultra result being 23 FPS at 1080p.

Q: What is the frame time consistency like?

A: The Medium preset shows relatively tight frame times: 33-44 FPS at 1080p, 24-33 FPS at 1440p, and 16-22 FPS at 4K. This suggests stable performance without major stutters, but the frame rates themselves are too low for smooth gameplay.

How This Combo Ranks

This configuration ranks 2568th out of 2902 tested combos for Red Dead Redemption 2, placing it in the bottom 11.5% of all systems tested. The ranking disparity between components is stark: the Ryzen 9 5950X sits at the 91st percentile among CPUs, while the Intel Arc B390 languishes at the 9th percentile among GPUs. This 82-percentile gap is among the largest possible mismatches, and the combo ranking reflects the weaker component.

The combo's rank of 2568 means that 334 tested configurations perform worse, but 2,567 perform better — the overwhelming majority. Given that the Arc B390's nearest GPU rivals are all NVIDIA parts from the early 2010s (GT 520MX, GeForce 800M, GT 625 OEM, GT 710), this system's performance class is closer to a decade-old laptop than a modern gaming desktop. The Ryzen 9 5950X's presence in the combo does nothing to boost the rank because the GPU is the sole determinant of frame rate in this title.

For context, the CPU's nearest rivals (Core Ultra 5 235HX, EPYC 8124P, Core i9-13900F, Core i7-14700) all have similar composite benchmark scores within 0.7% of the 5950X, but pairing any of them with the Arc B390 would produce nearly identical results in this game. The GPU's 9th percentile performance creates a hard ceiling that no CPU can overcome. The data clearly shows that the combo rank is entirely GPU-bound, and users seeking better performance would need to replace the integrated graphics with a discrete solution to see any meaningful improvement.

Settings Recommendations

The measured data provides a clear hierarchy of playability, and the recommendations are straightforward: sacrifice visual quality for frame rate, and stick to 1080p. The Low preset at 1080p is the only configuration that exceeds 50 FPS average, delivering 51 FPS. This should be the default choice for any user attempting to play this game on this hardware, as it provides the least stutter-prone experience.

If visual fidelity is a priority, the Medium preset at 1080p (39 FPS) is a reasonable compromise, offering a 12 FPS penalty over Low but with noticeably improved textures and effects. The High preset at 1080p (32 FPS) is playable but approaches the edge of comfort, while Ultra at 1080p (23 FPS) should be avoided due to frame pacing issues that become noticeable below 25 FPS.

At 1440p, the system is only viable at Low settings (38 FPS), with Medium (29 FPS) and High (24 FPS) pushing into uncomfortable territory and Ultra (17 FPS) being unplayable. At 4K, all presets fail to deliver acceptable performance: Low (25 FPS), Medium (19 FPS), High (16 FPS), and Ultra (11 FPS) are all below the threshold for smooth gameplay.

The optimal strategy is to run 1080p Low settings for maximum frame rate, or 1080p Medium if the user can tolerate occasional drops below 40 FPS. Higher resolutions and quality presets offer no viable experience — the GPU's 24 ROPs and shared memory bandwidth simply cannot sustain modern rendering workloads at those levels. Users seeking a true Red Dead Redemption 2 experience should consider this configuration as a demonstration of GPU bottlenecking rather than a practical gaming system.
