Downfall

The AMD Ryzen 9 7900X and AMD Radeon RX 6650 XT combination delivers a highly capable 1080p and 1440p experience in Downfall, but the data reveals a clear performance ceiling when pushing to 4K Ultra settings. The measured frame rates show a system where the CPU’s substantial multi-threaded horsepower is largely untapped, with the GPU becoming the definitive bottleneck at higher resolutions and quality presets. This pairing ranks 1114th out of 1741 tested combos for this title, placing it in the middle of the database field.

FAQ

Q: What is the average frame rate at 1080p High settings for this combo?

A: The AMD Ryzen 9 7900X with the RX 6650 XT produces an average of 131.9 FPS at 1920x1080 with High settings, indicating a very smooth experience for a horror title.

Q: How does the frame rate change when moving from 1080p to 4K at High settings?

A: At 1080p High the combo averages 131.9 FPS, but this drops to 96.4 FPS at 1440p and further to 61.5 FPS at 3840x2160. The performance scaling shows a substantial 70.4 FPS loss between 1080p and 4K.

Q: What is the performance difference between Low and Ultra settings at 1440p?

A: At 2560x1440, the average frame rate is 143.3 FPS on Low settings, which falls to 58.4 FPS on Ultra. This represents a 84.9 FPS drop, highlighting the significant cost of the Ultra preset.

Q: Is the CPU or GPU more likely to be the limiting factor at 4K Ultra?

A: The data strongly indicates the GPU is the limiting factor. At 4K Ultra the combo only manages 34.5 FPS, while the Ryzen 9 7900X’s benchmark scores (e.g., 43,695 in Cinebench R23 multi-core) show far more headroom than the GPU’s 72nd percentile ranking suggests.

*Q: How does this combo rank among all tested configurations in Downfall?*

A: The combination ranks 1114th out of 1741 tested combos. While this is below the median, the average frame rates at 1080p and 1440p remain playable.

Q: What is the frame rate at 4K Low settings?

A: At 3840x2160 with Low settings, the combo achieves an average of 87.8 FPS, which is a playable result, though the Ultra preset at the same resolution drops to 34.5 FPS.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, featuring 8 GB of GDDR6 memory on a 128-bit bus. Its memory bandwidth is rated at 280.3 GB/s, which is a critical factor for a horror game like Downfall that relies on detailed textures and atmospheric lighting. The GPU’s boost clock of 2635 MHz and game clock of 2410 MHz help drive its performance, but the 8 GB VRAM capacity is a potential constraint at higher resolutions, as the 4K Ultra results suggest.

The benchmark data positions this GPU at the 72nd percentile, with an average benchmark score of 29,024. Its nearest rivals include the AMD Radeon RX 6800M and the Intel Arc A370M, with delta percentages of 0.0% and -0.5% respectively. This indicates the RX 6650 XT is a mid-range performer, and the measured FPS in Downfall reflects this. At 1080p High, the 131.9 FPS average is strong, but the drop to 34.5 FPS at 4K Ultra shows the GPU’s limits when pushed with the highest settings.

The data reveals that the GPU’s performance is the primary driver of frame rate changes across settings. For instance, at 1440p, moving from Low to Medium reduces the average from 143.3 FPS to 118.1 FPS, and then to 96.4 FPS at High. The jump to Ultra at 1440p causes a severe drop to 58.4 FPS. This pattern is consistent with a GPU that has enough power for mainstream resolutions but struggles with the pixel count and shading complexity of 4K, especially with Ultra settings that likely increase memory pressure and fill-rate demands.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate is 131.9 FPS at 1080p, 96.4 FPS at 1440p, and 61.5 FPS at 4K. This represents a 26.9% drop from 1080p to 1440p, and a further 36.2% drop from 1440p to 4K. Such scaling is typical for a GPU-bound scenario, where the number of pixels rendered directly impacts the workload.

The analysis of Low and Ultra settings confirms this trend. At Low settings, the combo achieves 198.6 FPS at 1080p, 143.3 FPS at 1440p, and 87.8 FPS at 4K. The drop from 1080p to 4K is 110.8 FPS, which is a significant reduction but still keeps the game playable. In contrast, at Ultra settings, the frame rates are 82.2 FPS at 1080p, 58.4 FPS at 1440p, and a mere 34.5 FPS at 4K. The 47.7 FPS difference between 1080p and 4K at Ultra is proportionally similar to other settings, but the absolute numbers fall below the threshold for smooth gameplay.

These results indicate that the limiting component is the GPU. The CPU’s performance, as measured by its 3DMark scores (e.g., 12,536 at max threads), does not show a corresponding bottleneck at lower resolutions. The frame rate scaling is almost entirely dependent on resolution and settings, which is the signature of a GPU-limited configuration. For players targeting 1080p or 1440p, the RX 6650 XT provides ample performance, but 4K gaming requires significant compromises in quality settings to maintain acceptable frame rates.

How This Combo Ranks

The combo rank of 1114 out of 1741 tested configurations places this system in the lower-middle tier of the database for Downfall. This ranking is influenced by the GPU’s mid-range standing, as the CPU is a high-end part. The Ryzen 9 7900X sits at the 93rd percentile among all CPUs, with an average benchmark score of 50,556. Its nearest rivals include the Intel Core Ultra 5 235 (delta -0.1%) and the AMD Ryzen 9 5900XT (delta -0.4%), showing that the CPU is competitive with other top-tier processors.

However, the GPU’s 72nd percentile ranking and average score of 29,024 drags the overall combo down. The RX 6650 XT’s nearest rivals, such as the RX 6800M and RX 470, have very similar average scores, indicating that this GPU is at a performance plateau. In a game like Downfall, which appears to be GPU-intensive based on the scaling data, the GPU’s limitations become the primary factor in the combo’s ranking.

The rank of 1114 suggests that many other combinations of CPUs and GPUs in the database achieve higher average frame rates in this title. This is not surprising given that the RX 6650 XT is an end-of-life product and is positioned for 1080p gaming. The CPU’s powerful multi-threading capabilities are largely irrelevant for this game’s frame rate, as the bottleneck is clearly on the graphics side. If the goal is to maximize performance in Downfall, the data implies that a stronger GPU would yield a much higher rank than a faster CPU.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. It features 64 MB of shared L3 cache and supports DDR5 memory with a bandwidth of 83.2 GB/s. These specifications make it a formidable CPU for multi-threaded workloads, as evidenced by its Cinebench R23 multi-core score of 43,695 and PassMark multi-thread score of 51,406.

Despite this CPU’s capabilities, the benchmark results in Downfall indicate that it is not the limiting factor. The frame rates scale primarily with resolution and settings, which are GPU-dependent variables. For example, at 1080p Low, the combo achieves 198.6 FPS, which is high enough that the CPU’s single-thread performance (3DMark single-thread score of 1,093) is sufficient to feed the GPU. However, the CPU’s massive multi-thread potential is not utilized in this game, as Downfall likely benefits more from the GPU’s shading and texture throughput.

The CPU’s high percentile ranking (93rd) and average benchmark score of 50,556, which is only -0.1% behind the Intel Core Ultra 5 235, suggest that it would perform well in CPU-bound scenarios. However, in this particular combination, the RX 6650 XT cannot keep up with the CPU’s output at higher settings. The data shows that at 4K Ultra, the frame rate drops to 34.5 FPS, a level where even the fastest CPU would not help. Thus, the Ryzen 9 7900X provides a strong foundation for other tasks, but its role in Downfall is to avoid becoming a bottleneck at lower resolutions and settings, which it does effectively.
