Doom

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce GTX 1650 presents a stark contrast in capability within the 2016 FPS Doom. The data shows a combination where a top-tier processor is constrained by an entry-level graphics card, resulting in a specific performance profile that is heavily dependent on resolution and graphical settings.

Resolution Scaling

The measured FPS data illustrates a classic case of GPU-limited scaling as resolution increases. At 1920x1080 with Low settings, the combo achieves 90.9 FPS, which drops to 57.3 FPS at 2560x1440 and further to 33.8 FPS at 3840x2160. This represents a significant decline of approximately 63% from 1080p to 4K at Low settings. The pattern is consistent across all settings, with the frame rate at 4K being less than half of what is achieved at 1080p.

This steep drop-off indicates that the GTX 1650 is the limiting component at higher resolutions. The GPU's memory bandwidth of 128.1 GB/s and 4 GB of VRAM become increasingly stressed as pixel count rises. In contrast, the CPU's role diminishes at higher resolutions, as the workload shifts from geometry and draw calls to pixel shading and memory throughput. The data shows that at 1080p, the gap between Low and Ultra settings is 33.6 FPS (90.9 vs 57.3), while at 4K, this gap narrows to 14.7 FPS (33.8 vs 19.1). This narrowing suggests that at 4K, the GPU is saturated even at Low settings, leaving little headroom for additional graphical features.

GPU Role

The NVIDIA GeForce GTX 1650 is built on the Turing architecture with a base clock of 1485 MHz and a boost clock of 1665 MHz. Its memory configuration includes 4 GB of GDDR5 on a 128-bit bus, providing 128.1 GB/s of bandwidth. These specifications place the card in the 43rd percentile of all GPUs, with an average benchmark score of 8713. The nearest rivals include the NVIDIA GeForce RTX 3050 A Mobile (0.4% ahead) and the AMD Radeon 550X (0.4% ahead), indicating that this card sits in a narrow performance band.

In Doom, the GPU's limitations are evident in the frame rates. At 1080p Ultra, the card manages 57.3 FPS, which is identical to the 1440p Low result. This suggests that the GPU's shading units (896) and 32 ROPs are the primary bottleneck when pushing higher settings. The 4K Ultra result of 19.1 FPS confirms that this card is not suited for high-resolution gaming in this title. The card's 75 W TDP and lack of power connectors indicate its designed purpose as a low-power, entry-level solution, which is reflected in its performance ceiling.

How This Combo Ranks

The combination of the Ryzen 7 7800X3D and GTX 1650 ranks 1634 out of 1681 tested combos in Doom. This places it in the bottom 3% of all configurations, a ranking that is almost entirely attributable to the GPU's performance. The CPU, by contrast, is a high-end part that ranks in the 87th percentile of all CPUs.

When examining the CPU's benchmark scores, the Ryzen 7 7800X3D achieves an average score of 31580, with nearest rivals including the Intel Core i7-12700F (0.1% behind) and the AMD Ryzen 9 5980HX (0.3% behind). This indicates that the processor is capable of delivering exceptional frame rates in CPU-bound scenarios. However, in this specific combo, the GPU's 43rd percentile ranking dominates the overall result. The rank of 1634 out of 1681 is a clear indicator that the system is heavily imbalanced, with the GPU unable to keep pace with the CPU's potential.

Measured FPS Breakdown

The measured FPS data provides a detailed view of performance across resolutions and settings.

At 1920x1080, the combo delivers its best results. Low settings produce 90.9 FPS, which is smooth for fast-paced FPS gameplay. Medium settings yield 77.7 FPS, High settings result in 68.0 FPS, and Ultra settings drop to 57.3 FPS. This shows a linear progression where each settings tier costs roughly 10-12 FPS, indicating that the GPU is still managing the workload but is nearing its limits at Ultra.

At 2560x1440, the performance drops noticeably. Low settings achieve 57.3 FPS, which is the same as 1080p Ultra. Medium settings produce 50.6 FPS, High settings yield 43.6 FPS, and Ultra settings fall to 36.2 FPS. The delta between Low and Ultra at this resolution is 21.1 FPS, showing that the GPU is struggling more with the increased pixel count.

At 3840x2160, the combo is clearly out of its depth. Low settings drop to 33.8 FPS, Medium to 29.0 FPS, High to 25.3 FPS, and Ultra to 19.1 FPS. None of these results are playable for a smooth experience, and the gap between Low and Ultra narrows to just 14.7 FPS. This indicates that at 4K, the GPU is completely saturated and settings have a diminished impact on frame rate. The data shows a consistent pattern: 1080p is the only resolution where the combo can maintain above 60 FPS, and only at Low and Medium settings.

CPU Role

The AMD Ryzen 7 7800X3D is a 7000 series processor with 8 cores and 16 threads, based on the Zen 4 architecture. Its base clock is 4.20 GHz with a boost clock of 5.00 GHz. It features 96 MB of shared L3 cache, which is a significant advantage for gaming workloads. The CPU's benchmark results are strong, with a Cinebench R23 multicore score of 29149 and a single-core score of 4115.

In Doom, the CPU's role is to feed the GPU with draw calls and process game logic. Given the GTX 1650's limitations, the CPU is rarely the bottleneck. The data shows that at 1080p Low, the combo achieves 90.9 FPS, which is likely near the GPU's maximum. If the CPU were the limiting factor, we would expect to see similar frame rates across different resolutions, but the significant drop at 4K confirms that the GPU is the constraint. The 3DMark 16-thread score of 7980 and 2-thread score of 1887 indicate that the CPU has ample headroom for this game, which is not heavily multi-threaded but does benefit from high single-thread performance. The 7800X3D's 5.0 GHz boost clock and large cache allow it to handle the game's engine without breaking a sweat, making the GTX 1650 the definitive performance ceiling.

FAQ
