Doom

The AMD Ryzen 5 4600G and NVIDIA GeForce GTX 1650 combination delivers a playable experience at 1080p in Doom, but the data clearly shows that the GPU is the primary bottleneck at higher resolutions. The measured frame rates demonstrate a severe performance cliff as resolution increases, with the system struggling to maintain fluid gameplay beyond 1440p. This pairing is best suited for 1080p gaming, where it achieves respectable average frame rates across most settings presets.

Resolution Scaling

The performance drop from 1080p to 4K is dramatic and reveals the limiting component clearly. At 1080p with High settings, the combo produces 70.3 FPS, but at 1440p the same settings yield 41.6 FPS, and at 4K the frame rate collapses to 26.6 FPS. This represents a roughly 62% reduction in frame rate when moving from 1080p to 4K at High settings. The scaling pattern is consistent across all settings presets, confirming that the GPU is the primary constraint.

The 4K results are particularly telling. At 4K Ultra, the system only manages 18.1 FPS, which is unplayable. Even at 4K Low, the frame rate only reaches 34 FPS, still below the 60 FPS threshold for smooth gameplay. The 1440p results are mixed: Low settings achieve 60.4 FPS, which is acceptable, but High settings drop to 41.6 FPS and Ultra falls to 35.1 FPS. The data indicates that this combination is not viable for 4K gaming and only marginally playable at 1440p with reduced settings.

The scaling pattern suggests the CPU is not the limiting factor at lower resolutions. At 1080p, the system delivers 92.8 FPS on Low settings, indicating the Ryzen 5 4600G can feed the GPU sufficiently at this resolution. However, as resolution increases, the GPU's workload grows exponentially, and the GTX 1650's limited processing power becomes the dominant constraint. The frame rate drops are consistent with GPU-bound behavior rather than CPU limitations.

How This Combo Ranks

The combination ranks 1624 out of 1681 tested combos for Doom, placing it in the bottom 3.4% of all tested systems. This is a remarkably low ranking that reflects the GTX 1650's modest performance in this title. The CPU itself is not the issue; the Ryzen 5 4600G holds a 75th percentile ranking across all CPUs and is competitive with its nearest rivals. However, the GPU ranks in the 43rd percentile, pulling the overall combo ranking down significantly.

The CPU's nearest rivals show it is well-positioned. The Ryzen 5 4600G scores 17,489 in the average benchmark, essentially tied with the AMD Ryzen 3 PRO 5355GE at 17,482 and the Intel Core i5-12450H at 17,475. It trails the Intel Core i3-14100T by 0.8% and the Intel Core i3-13100F by 1%. This indicates the processor is not a weak link in the system.

The GPU's nearest rivals paint a different picture. The GTX 1650 scores 8,713 on average, nearly identical to the NVIDIA GeForce RTX 3050 A Mobile (8,746, -0.4% delta) and the AMD Radeon 550X (8,749, -0.4% delta). It slightly outperforms the NVIDIA Quadro P2200 (8,671, +0.5% delta) and the AMD Radeon Pro WX 5100 (8,761, -0.5% delta). This tight grouping shows the GTX 1650 is a mid-pack performer among its immediate peers, but none of these cards are high-end options.

GPU Role

The GTX 1650 features 4 GB of GDDR5 memory on a 128-bit bus, providing 128.1 GB/s of bandwidth. The card has 896 shading units, 56 texture mapping units, and 32 raster operation units. Its base clock runs at 1485 MHz with a boost clock of 1665 MHz, and memory operates at 2001 MHz (8 Gbps effective). The card delivers 2.984 TFLOPS of FP32 performance.

The 4 GB VRAM capacity is a critical limitation in Doom. At 4K Ultra settings, the game requires more memory than available, resulting in the 18.1 FPS average. The memory bandwidth of 128.1 GB/s also becomes a bottleneck at higher resolutions, as the GPU cannot feed data to the processing units quickly enough. The card's pixel rate of 53.28 GPixel/s and texture rate of 93.24 GTexel/s are simply insufficient for 4K workloads.

The GPU's performance in benchmark tests shows its capability. The passmark G3D score of 7,880 and 3DMark Steel Nomad DX12 score of 305 indicate modest performance. The Geekbench OpenCL score of 39,112 and Vulkan score of 35,966 are also moderate. These scores align with the observed gaming performance, confirming the GPU is the limiting factor in this combo.

FAQ

*Q: What is the best resolution for this combo in Doom?*

A: The measured data shows 1920x1080 is the only resolution where the system consistently exceeds 50 FPS across most settings. At 1440p, only Low settings reach 60 FPS, while 4K results are all below 35 FPS.

Q: How does the GPU compare to its nearest rivals?

A: The GTX 1650 scores 8,713 on average, with the RTX 3050 A Mobile at 8,746 (-0.4%), Radeon 550X at 8,749 (-0.4%), Quadro P2200 at 8,671 (+0.5%), and Radeon Pro WX 5100 at 8,761 (-0.5%). The differences are minimal.

Q: Is the CPU holding back performance?

A: No. The Ryzen 5 4600G ranks in the 75th percentile for all CPUs and scores 17,489 on average, competitive with its nearest rivals. The GPU is the bottleneck, as shown by the severe frame rate drops at higher resolutions.

CPU Role

The Ryzen 5 4600G is a 6-core, 12-thread processor based on Zen 2 architecture (Renoir). It operates at a base clock of 3.70 GHz with a boost clock of 4.20 GHz. The CPU has a 65 W TDP and supports DDR4 memory through a dual-channel interface, providing 51.2 GB/s of memory bandwidth. It features 8 MB of shared L3 cache and 512 KB of L2 cache per core.

The processor's benchmark scores indicate it is more than capable for gaming. The Cinebench R23 multicore score of 13,593 and single-core score of 1,919 show strong performance. The PassMark multithread score of 15,992 and single-thread score of 2,653 further confirm its capability. The 3DMark scores of 4,889 for max threads and 726 for single thread suggest the CPU can handle demanding workloads without bottlenecking mid-range GPUs.

In Doom, the CPU's role is secondary to the GPU. The 1080p Low setting produces 92.8 FPS, indicating the processor can feed the GPU adequately at this resolution. The lack of frame rate variation between Low and Ultra at 1080p (92.8 FPS vs 53.1 FPS) is primarily due to GPU workload changes rather than CPU limitations. The CPU's 12 threads are sufficient for Doom's engine, which does not heavily utilize many cores.

Settings Recommendations

For 1080p gaming, the High preset at 70.3 FPS provides the best balance of visual quality and performance. The Medium preset at 81.9 FPS offers a smoother experience with slightly reduced visuals, while Low at 92.8 FPS maximizes frame rate for competitive play. Ultra at 53.1 FPS is playable but below the 60 FPS threshold, making it less ideal for fast-paced action.

At 1440p, the Low preset at 60.4 FPS is the only option that achieves smooth gameplay. Medium at 51.9 FPS is borderline, and High at 41.6 FPS is noticeably less fluid. The Ultra preset at 35.1 FPS is not recommended. For 4K, none of the settings presets are viable; the best result is Low at 34 FPS, which remains below playable standards.

The data suggests 1080p with High settings is the sweet spot for this combo. It delivers 70.3 FPS, which is well above the 60 FPS target, while maintaining good visual fidelity. Users prioritizing frame rate over visuals should consider Medium at 81.9 FPS, while those with 1440p monitors can achieve playable performance only at Low settings.

Measured FPS Breakdown

At 3840x2160, the system produces 26.6 FPS on High, 34 FPS on Low, 25.8 FPS on Medium, and 18.1 FPS on Ultra. These results show that even the lowest settings cannot achieve playable frame rates at 4K.

At 2560x1440, the measured results are 41.6 FPS on High, 60.4 FPS on Low, 51.9 FPS on Medium, and 35.1 FPS on Ultra. Only the Low preset reaches the 60 FPS target, with Medium approaching playable levels at 51.9 FPS.

At 1920x1080, the system achieves 70.3 FPS on High, 92.8 FPS on Low, 81.9 FPS on Medium, and 53.1 FPS on Ultra. This is the only resolution where multiple presets deliver smooth, playable performance. The frame rate progression from Low to Ultra shows a consistent decline, with Ultra falling below the 60 FPS threshold.
