Downfall

The AMD Ryzen 5 2600 paired with the AMD Radeon RX 7900 XTX presents a striking generational mismatch in Downfall. The data shows a system where the GPU’s raw horsepower is frequently held in check by an older six-core processor, yet the sheer scale of the Radeon’s capabilities still delivers high refresh rates at most settings. This analysis breaks down how the combination behaves across resolutions, what the CPU contributes, and where the final ranking places it among 1,741 tested combos.

Resolution Scaling

The measured FPS data reveals how the performance ceiling shifts as resolution increases. At 1080p with Low settings, the combo produces 251.1 FPS, which drops to 224.3 FPS at 1440p and further to 159.8 FPS at 4K. This scaling pattern—a 36% reduction from 1080p to 4K—indicates that the GPU is not the primary limiter at lower resolutions. If the RX 7900 XTX were fully utilized at 1080p, the frame rate would remain nearly flat across resolutions until the GPU became the bottleneck.

The situation changes dramatically when moving from Low to Ultra settings. At 4K Ultra, the average FPS plummets to 66, a 59% drop from the 4K Low result. This steep decline shows that at 4K with maxed settings, the GPU’s compute and memory resources are saturated, and the CPU’s older architecture becomes less of a factor. The 1440p results tell a similar story: Ultra yields 107.6 FPS versus 224.3 FPS at Low, a 52% reduction. At 1080p, the gap narrows slightly—154.2 FPS at Ultra versus 251.1 FPS at Low, a 39% drop—suggesting that the CPU is still imposing a ceiling even when the GPU is less stressed.

Looking at the High setting across resolutions, the frame rates are 215.2 FPS at 1080p, 177 FPS at 1440p, and 109 FPS at 4K. The 1080p-to-1440p decline of 18% is modest, but the 1440p-to-4K drop of 38% is sharper. This indicates that the RX 7900 XTX begins to take over as the limiting component around 1440p High, with the CPU’s influence waning as pixel count rises. For gamers targeting high refresh rates, the data suggests that 1080p and 1440p with Low or Medium settings are where this combo shines, while 4K Ultra is clearly GPU-bound territory.

CPU Role

The Ryzen 5 2600 is a 2000-series chip with 6 cores and 12 threads, running at a base clock of 3.40 GHz and a boost clock of 3.90 GHz. It belongs to the Zen+ architecture, built on a 12 nm process at GlobalFoundries. In Downfall, a horror title that does not heavily multithread, the CPU’s single-thread performance is often the deciding factor. The Cinebench R23 single-core score of 1,579 and multi-core score of 11,186 illustrate a processor that was mid-range at its 2018 release, but now sits far behind modern parts.

The benchmark data shows the Ryzen 5 2600 achieves a 77th percentile ranking among all CPUs, with an average benchmark score of 19,616. Its nearest rivals include the Intel Core i5-1345U (19,691, -0.4% delta) and the AMD Ryzen 5 7530U (19,508, +0.6% delta), which are both mobile processors. This places the desktop 2600 in the same performance tier as efficient laptop chips, underscoring its age. The 16 MB of shared L3 cache and dual-channel DDR4 memory support (with 46.9 GB/s bandwidth) are adequate for the era, but they are not enough to feed a flagship GPU like the RX 7900 XTX in CPU-bound scenes.

In Downfall, the CPU’s role is most evident at 1080p Low. The 251.1 FPS result is likely close to the maximum the Ryzen 5 2600 can produce, as the GPU is barely breaking a sweat. The fact that 1440p Low still hits 224.3 FPS—only an 11% drop—confirms that the CPU is the anchor at these settings. When the resolution rises to 4K Low, the frame rate falls to 159.8 FPS, a 29% reduction from 1080p, which suggests the GPU is finally starting to contribute to the bottleneck. The data consistently points to a CPU that limits top-end frame rates but does not prevent playable performance.

How This Combo Ranks

The combination of the Ryzen 5 2600 and RX 7900 XTX ranks 393rd out of 1,741 tested combos in Downfall. This places it in the top 22.6% of all configurations, which is respectable given the CPU’s age. However, the ranking also reflects how much headroom is left on the table. The GPU alone sits in the 85th percentile among all GPUs, with an average benchmark score of 44,019, while the CPU’s 77th percentile is notably lower. The mismatch is clear: the GPU is a top-tier part, but the CPU drags the overall combo down.

The nearest GPU rivals to the RX 7900 XTX include the AMD Radeon Pro 580 (44,195, -0.4% delta) and the NVIDIA GeForce RTX 4090 Mobile (43,667, +0.8% delta). These comparisons are based on average benchmark scores, not Downfall specifically, but they show that the GPU is competitive with other high-end parts. If the CPU were upgraded to a modern chip, the combo rank would likely climb significantly, as the GPU has plenty of untapped performance in CPU-limited scenarios.

The rank of 393 out of 1,741 indicates that 1,348 combos perform worse, but also that 392 combos perform better. For a system with a 2018 CPU and a 2022 GPU, this is a reasonable outcome. The data suggests that users with this pairing are getting a playable experience at most settings, but they are leaving performance on the table compared to more balanced builds.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings. At 1080p, the results are as follows: Low produces 251.1 FPS, Medium 234.9 FPS, High 215.2 FPS, and Ultra 154.2 FPS. The gap between Low and Ultra is 97 FPS, or 39%, which shows how much the CPU limits the top end. Even at Ultra, the frame rate is well above 144 Hz, making this a strong setup for high-refresh 1080p monitors.

Moving to 1440p, the frame rates are 224.3 FPS at Low, 206.3 FPS at Medium, 177 FPS at High, and 107.6 FPS at Ultra. The Ultra setting takes a significant hit, dropping 65% from Low, which indicates the GPU is now the dominant factor. The High setting at 177 FPS is still excellent for most displays, and the Medium setting at 206.3 FPS is similarly impressive. The 1440p results show that this combo is well-suited for competitive play, where lower settings can push frame rates past 200 FPS.

At 4K, the data reveals a more challenging environment. Low produces 159.8 FPS, Medium 130.6 FPS, High 109 FPS, and Ultra falls to 66 FPS. The Ultra result is the only one that dips below 60 FPS, and it is a 59% reduction from the Low setting. The 4K High result of 109 FPS is still smooth, but the gap between Medium and High is 21 FPS, indicating that the GPU is working hard. The 4K Low result of 159.8 FPS is surprising for a CPU-limited system, but it shows that at this resolution, the GPU’s 24 GB of VRAM and 960 GB/s bandwidth can compensate for the older CPU.

Across all resolutions, the Medium setting consistently offers a balanced experience, with frame rates of 234.9 FPS at 1080p, 206.3 FPS at 1440p, and 130.6 FPS at 4K. The data indicates that this combo is most effective when the settings are kept at Medium or below, allowing the RX 7900 XTX to stretch its legs without being fully bottlenecked by the Ryzen 5 2600.

GPU Role

The AMD Radeon RX 7900 XTX is a RDNA 3.0 part built on the Navi 31 chip, using a 5 nm process at TSMC. It features 6,144 shading units, 384 texture mapping units, and 192 render output units, along with 96 ray tracing cores. The GPU’s clocks are 1,929 MHz base, 2,365 MHz game, and 2,498 MHz boost, with memory running at 2,500 MHz (20 Gbps effective). The 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which is crucial for high-resolution textures in Downfall.

The GPU’s benchmark results show a 3DMark Steel Nomad DX12 score of 6,841, a Geekbench OpenCL score of 189,573, and a Geekbench Vulkan score of 192,597. It also achieves a Passmark G3D score of 31,238 and a Passmark GPU Compute score of 17,689. These numbers place the GPU in the 85th percentile among all GPUs, with an average benchmark score of 44,019. The RX 7900 XTX is a top-tier part, and its performance in Downfall reflects that—when the CPU is not the bottleneck, the GPU delivers exceptional frame rates.

The GPU’s role is most apparent at 4K Ultra, where it produces 66 FPS. This is the only setting where the GPU is clearly the limiting factor, and it still manages a playable frame rate. At 4K Low, the GPU produces 159.8 FPS, which reflects its raw power. The 24 GB VRAM is more than sufficient for Downfall, even at 4K, and the 960 GB/s bandwidth ensures that texture streaming is never a problem. The GPU’s TDP of 355 W and dual-slot design are typical for a flagship, but the data shows that the performance justifies the power draw.

The RX 7900 XTX’s nearest rivals include the AMD Radeon Pro 580 (44,195 avg score, -0.4% delta) and the NVIDIA GeForce RTX 4090 Mobile (43,667 avg score, +0.8% delta). These comparisons, based on average benchmark scores, show that the GPU is competitive with other high-end parts. In Downfall, the GPU’s performance is consistently strong, but the Ryzen 5 2600 prevents it from reaching its full potential at lower resolutions. The data suggests that the GPU is the star of this combo, and a CPU upgrade would unlock even higher frame rates.
