Red Dead Redemption 2

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 3080 delivers a nuanced performance profile in Red Dead Redemption 2, where the balance between the CPU and GPU shifts dramatically depending on the selected resolution and quality preset. Analysis of the measured frame rates reveals a system that is exceptionally strong at 1080p, where it can exceed 146 FPS on Low settings, but which becomes increasingly GPU-bound as resolution climbs to 4K, where even High settings drop to 43.7 FPS. This data indicates that while the 12-core processor provides ample headroom, the 10 GB graphics card is the primary limiter at higher pixel counts, a conclusion supported by the scaling patterns across the tested configurations.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 clearly illustrates the transition from a CPU-leaning workload to a GPU-dominated one. At 1080p with Low settings, the combo achieves 146.5 FPS, which drops to 106.9 FPS at 1440p and further to 71.7 FPS at 4K. This represents a 51% reduction in frame rate from 1080p to 4K on Low settings, a relatively modest decline that suggests the processor is still contributing meaningfully to performance at lower resolutions. However, the scaling becomes much steeper when quality settings are increased. At Ultra settings, the frame rate falls from 66.3 FPS at 1080p to 46.6 FPS at 1440p, and finally to 35 FPS at 4K—a 47% drop from 1080p to 4K.

The pattern shifts dramatically when examining the High preset, which is the most demanding common configuration. At 1080p High, the system produces 92.6 FPS, but this plummets to 70.7 FPS at 1440p and 43.7 FPS at 4K. The 52.8% decrease from 1080p to 4K on High settings is the steepest of all presets, indicating that the combination of high resolution and elevated quality settings places an overwhelming burden on the GPU. Interestingly, the Medium preset shows a more linear scaling, with 106.4 FPS at 1080p, 83.1 FPS at 1440p, and 54.9 FPS at 4K. The data suggests that at 1080p, the RTX 3080 has sufficient headroom to allow the CPU to influence results, but by 4K, the GPU's raw throughput—characterized by its 8704 shading units and 760.3 GB/s memory bandwidth—becomes the sole determinant of performance.

How This Combo Ranks

Within the benchmark database, this specific combination of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 3080 achieves a rank of 512 out of 1687 tested combos in Red Dead Redemption 2. This places the system in the upper third of all configurations, though not at the absolute pinnacle of performance. The ranking reflects a balanced pairing where neither component is a significant bottleneck, but where the GPU's age relative to newer architectures prevents higher placement. The RTX 3080 itself holds a percentile of 80 among all GPUs, with an average benchmark score of 35787, while the CPU sits at the 93rd percentile with an average score of 50556.

The GPU's nearest rivals provide context for its position. The AMD Radeon Pro Duo sits just 0.2% ahead, while the AMD Radeon 880M trails by 0.4%, and the AMD Radeon RX 7900 GRE is 0.9% ahead. The NVIDIA GeForce RTX 5070 Ti Mobile is 1% behind. These small deltas indicate that the RTX 3080 remains competitive with newer hardware in synthetic benchmarks, though its real-world gaming performance in this title is constrained by its 10 GB memory capacity and 320-bit bus width. For the CPU, the nearest rivals include the Intel Core Ultra 5 235 at -0.1%, AMD Ryzen 9 5900XT at -0.4%, Intel Core i7-13850HX at -0.5%, and Intel Core i9-13980HX at -0.8%, all of which are within a single percentage point of the 7900X's average score. This clustering suggests that the processor is not a differentiating factor in this game's performance.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, fabricated on a 5 nm process by TSMC. It operates with a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with 64 MB of shared L3 cache. In Red Dead Redemption 2, which is known for its demanding open-world environments and complex AI simulations, the CPU's multi-threaded capabilities are relevant, though the game does not fully utilize all 24 threads. The 3DMark benchmark scores show a strong scaling from 2 threads (2137) to 8 threads (7798), but the jump to 16 threads (10972) and max threads (12536) indicates diminishing returns beyond eight cores. This suggests that the game's engine primarily leverages a handful of cores, with additional threads providing only marginal benefits.

The CPU's single-thread performance is also a factor, as evidenced by the 3DMark single-thread score of 1093 and Cinebench R23 single-core score of 6168. In this game, the frame rate at 1080p Low settings (146.5 FPS) demonstrates that the processor can feed the GPU effectively at lower resolutions. However, the relatively small performance difference between 1080p Medium (106.4 FPS) and 1440p Medium (83.1 FPS)—a 21.9% drop—suggests that the CPU is not the primary constraint at higher resolutions. The Ryzen 9 7900X's position at the 93rd percentile among all CPUs, with an average benchmark score of 50556, reinforces its capability, but the game's performance ceiling is clearly set by the graphics card. The processor's 170 W TDP and DDR5 memory support with 83.2 GB/s bandwidth provide a solid foundation, yet the data shows that even this high-end CPU cannot compensate for the GPU's limitations at 4K Ultra, where the frame rate drops to 35 FPS.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality settings. At 1920x1080, the system delivers 146.5 FPS on Low, 106.4 FPS on Medium, 92.6 FPS on High, and 66.3 FPS on Ultra. The progression from Low to Ultra represents a 54.7% reduction in frame rate, indicating that quality settings have a substantial impact at this resolution. At 2560x1440, the figures are 106.9 FPS on Low, 83.1 FPS on Medium, 70.7 FPS on High, and 46.6 FPS on Ultra. The drop from Low to Ultra at 1440p is 56.4%, which is slightly steeper than at 1080p, suggesting that the GPU is becoming more stressed. At 3840x2160, the performance is 71.7 FPS on Low, 54.9 FPS on Medium, 43.7 FPS on High, and 35 FPS on Ultra. The Low-to-Ultra reduction at 4K is 51.2%, which is actually less severe than at lower resolutions, indicating that the GPU is already saturated at Low settings and the additional quality options do not proportionally increase the workload.

Comparing resolutions for each preset, the scaling is consistent. For Low settings, moving from 1080p to 1440p reduces frame rate by 27%, and from 1440p to 4K by 33%. For Medium, the reductions are 21.9% and 33.9%, respectively. For High, the reductions are 23.7% and 38.2%, respectively. For Ultra, the reductions are 29.7% and 24.9%, respectively. The Ultra preset shows a less steep decline from 1440p to 4K, which may be due to the CPU becoming more involved at lower resolutions. Overall, the data indicates that for smooth gameplay at 60 FPS, the user must select Medium settings at 1440p (83.1 FPS) or Low settings at 4K (71.7 FPS), while High settings at 4K fall below 60 FPS at 43.7 FPS.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with a GA102 chip, fabricated on an 8 nm process by Samsung. It features 8704 shading units, 272 texture mapping units, and 96 render output units, along with 68 ray tracing cores and 272 tensor cores. The GPU operates at a base clock of 1440 MHz and a boost clock of 1710 MHz, with 10 GB of GDDR6X memory on a 320-bit bus, providing 760.3 GB/s of bandwidth. The GPU's FP32 performance is rated at 29.77 TFLOPS, with a pixel rate of 164.2 GPixel/s and a texture rate of 465.1 GTexel/s. These specifications position the RTX 3080 as a high-end card from its generation, but its performance in Red Dead Redemption 2 is ultimately limited by its memory capacity and bandwidth.

The 10 GB VRAM is a critical factor at 4K resolution, where the game's high-resolution textures and detailed environments can exceed this capacity. The measured performance at 4K Ultra (35 FPS) and 4K High (43.7 FPS) suggests that the GPU is struggling with memory bandwidth, as the 760.3 GB/s is insufficient for the demands of this title at high resolutions. The RTX 3080's percentile of 80 among all GPUs, with an average benchmark score of 35787, places it in the upper tier, but its performance in this specific game is below what newer architectures achieve. The nearest rivals, including the AMD Radeon RX 7900 GRE at -0.9% and the Radeon Pro Duo at -0.2%, indicate that the GPU is competitive with other high-end options, yet the real-world frame rates show that it cannot maintain 60 FPS at 4K with high-quality settings.

The GPU's memory clock of 1188 MHz, effective 19 Gbps, and its 320-bit bus width are the primary constraints at higher resolutions. At 1080p, the GPU has ample bandwidth, as evidenced by the 146.5 FPS on Low settings, but the demands of 4K quickly saturate the memory subsystem. The 68 RT cores do not appear to be heavily utilized in this game, as the frame rates do not improve significantly when comparing Low and Medium settings at 4K (71.7 FPS vs. 54.9 FPS). This indicates that the GPU's rasterization performance, rather than its ray tracing capabilities, is the limiting factor. The data suggests that for optimal performance in Red Dead Redemption 2, the RTX 3080 should be paired with a 1440p monitor and Medium to High settings, where it can deliver between 70.7 and 83.1 FPS.
