Doom

Resolution Scaling

The measured FPS trajectory across resolutions tells a clear story about where this pairing's bottleneck lives. At 1920x1080 with Low settings, the combo produces 93.4 FPS. Step up to 2560x1440 Low, and that figure drops to 57.3 FPS — a 38.7% reduction in frame rate from a 77.8% increase in pixel count. Push further to 3840x2160 Low, and the average falls to 35.1 FPS, which is 62.4% below the 1080p result. This is not a linear scaling pattern; the frame rate decays faster than pixel count increases, which indicates the GPU is the primary limiting component.

The pattern holds across all settings tiers. At High settings, the drop from 1080p (68 FPS) to 1440p (41.7 FPS) represents a 38.7% decline, while moving from 1440p to 4K (24.3 FPS) costs another 41.7%. The Ultra preset shows similar behavior: 56.7 FPS at 1080p, 37.3 FPS at 1440p, and 18.5 FPS at 4K. The 4K Ultra result is particularly telling — it is less than one-third of the 1080p Low figure, and it falls below the 24 FPS threshold that many players consider the absolute minimum for playable motion.

The fact that even Low settings cannot maintain 60 FPS at 1440p (57.3 FPS) reinforces the GPU-bound conclusion. The AMD Ryzen 7 5800XT has 8 cores and 16 threads with a boost clock of 4.80 GHz, and its Cinebench R23 multicore score of 23794 places it in the 86th percentile of all CPUs. A processor of this caliber is not going to be the constraint in a game like Doom at these resolutions. The data suggests that the GTX 1650's 128-bit memory bus and 128.1 GB/s bandwidth simply cannot feed the frame buffer fast enough as resolution increases.

How This Combo Ranks

Within the database of tested CPU-GPU combinations for Doom, this pairing sits at rank 1610 out of 1681 combos. That places it in the bottom 4.2% of all tested configurations. This is a low rank, and it tracks with the GPU's overall standing: the GTX 1650 sits in the 43rd percentile of all GPUs, with an average benchmark score of 8713. Its nearest rivals in synthetic testing include the NVIDIA Quadro P2200 (8671, 0.5% slower), the NVIDIA GeForce RTX 3050 A Mobile (8746, 0.4% faster), and the AMD Radeon 550X (8749, 0.4% faster).

The CPU component of this combo, by contrast, is far more capable. The Ryzen 7 5800XT's average benchmark score of 29774 places it near the AMD Ryzen 7 PRO 5755GE (29740, 0.1% slower) and the AMD Ryzen AI 7 PRO 360 (29682, 0.3% slower). It slightly trails the AMD Ryzen 7 7840H (29868, 0.3% faster) and the AMD Ryzen 7 6800HS (29856, 0.3% faster). The delta between CPU and GPU capability is stark: a processor in the 86th percentile paired with a graphics card in the 43rd percentile.

In Doom specifically, this mismatch manifests as a combo rank that is far lower than what the CPU alone would suggest. The game's engine is well-known for scaling with GPU throughput, and the measured FPS data confirms that the GTX 1650 is the ceiling. A combo rank of 1610 out of 1681 means that the vast majority of tested pairings outperform this one in Doom, regardless of their CPU choice. The Ryzen 7 5800XT's headroom is largely unused in this configuration at higher resolutions.

Settings Recommendations

The measured FPS data provides a clear hierarchy for playable settings at each resolution. At 1920x1080, Low settings deliver 93.4 FPS, which is comfortably above the 60 FPS target. Medium settings still produce 81 FPS, and High settings manage 68 FPS. Ultra drops to 56.7 FPS, which falls below the 60 FPS mark but remains playable for many users. For 1080p, High settings represent the best balance: it delivers 68 FPS while offering substantially better visual quality than Medium or Low, and it stays above the 60 FPS threshold.

At 2560x1440, the situation changes. Low settings produce 57.3 FPS, which is below 60 but close enough that most players would find it acceptable. Medium settings drop to 51.4 FPS, High to 41.7 FPS, and Ultra to 37.3 FPS. None of the 1440p presets maintain a consistent 60 FPS. The recommendation here is Low settings if frame rate is the priority; Medium if visual fidelity matters more and the player can tolerate sub-60 performance. High and Ultra at 1440p are difficult to justify given the substantial frame rate penalties.

At 3840x2160, the GTX 1650 is overmatched. Low settings yield 35.1 FPS, Medium drops to 28.8 FPS, High to 24.3 FPS, and Ultra to 18.5 FPS. Even the lowest preset falls well short of 60 FPS, and the 4K Ultra figure of 18.5 FPS is below the threshold for smooth motion in a fast-paced FPS. The data suggests that 4K is not a viable resolution for this combo in Doom, regardless of settings. Players with 4K displays should consider running the game at 1080p or 1440p instead.

Measured FPS Breakdown

At 1920x1080, the full settings range was measured. Low settings produced an average of 93.4 FPS. Medium settings delivered 81 FPS, which is 13.3% lower than Low. High settings measured 68 FPS, a 27.2% reduction from Low. Ultra settings fell to 56.7 FPS, which is 39.3% below the Low preset. The spread from Low to Ultra at 1080p is 36.7 FPS, indicating that the GPU has enough headroom at this resolution to absorb significant settings increases while remaining playable.

At 2560x1440, the measured values compress downward. Low settings averaged 57.3 FPS. Medium settings delivered 51.4 FPS, a 10.3% drop from Low. High settings measured 41.7 FPS, a 27.2% reduction. Ultra settings produced 37.3 FPS, which is 34.9% below Low. The gap between Low and Ultra at 1440p is 20 FPS, narrower than at 1080p, which reflects the increased pixel load limiting the GPU's ability to differentiate settings.

At 3840x2160, the values fall further. Low settings measured 35.1 FPS. Medium settings delivered 28.8 FPS, an 18.0% drop. High settings produced 24.3 FPS, a 30.8% reduction from Low. Ultra settings fell to 18.5 FPS, which is 47.3% below Low. The Low-to-Ultra spread at 4K is 16.6 FPS, the smallest of any resolution, confirming that the GPU is saturated and settings changes have diminishing returns.

The scaling efficiency across resolutions is worth noting. At Low settings, moving from 1080p to 1440p costs 36.1 FPS (93.4 to 57.3), and moving from 1440p to 4K costs 22.2 FPS (57.3 to 35.1). At Ultra settings, the same transitions cost 19.4 FPS (56.7 to 37.3) and 18.8 FPS (37.3 to 18.5). The diminishing absolute drops at higher resolutions indicate that the GPU is running out of throughput headroom.

GPU Role

The NVIDIA GeForce GTX 1650 is built on the TU117 chip using a 12 nm process from TSMC, with 4,700 million transistors on a 200 mm² die. Its base clock is 1485 MHz with a boost clock of 1665 MHz, and memory runs at 2001 MHz (8 Gbps effective). The 4 GB of GDDR5 memory on a 128-bit bus provides 128.1 GB/s of bandwidth. The GPU has 896 shading units, 56 TMUs, and 32 ROPs, with a texture rate of 93.24 GTexel/s and a pixel rate of 53.28 GPixel/s. FP32 performance is rated at 2.984 TFLOPS.

In Doom, these specifications translate into the measured FPS figures. The 4 GB VRAM capacity is not the primary constraint at the tested settings — the frame rates are more consistent with a fill-rate or shader-throughput limitation. The 128.1 GB/s memory bandwidth is modest by modern standards, and the resolution scaling pattern suggests that memory bandwidth becomes increasingly important as pixel count rises. At 1080p Low, the GPU can sustain 93.4 FPS, which indicates that the core has enough throughput for the game's demands when the pixel load is low. At 4K Ultra, the 18.5 FPS result shows that the combination of high pixel count and intensive shading overwhelms the GPU.

The GTX 1650's percentile rank of 43 places it near the middle-bottom of all GPUs. Its average benchmark score of 8713 is close to the NVIDIA Quadro P2200 (8671), the AMD Radeon 550X (8749), and the NVIDIA GeForce RTX 3050 A Mobile (8746). The GPU's launch MSRP was 149 USD, but that is not a factor in its measured performance. The data shows a GPU that is adequate for 1080p gaming at medium-to-high settings in Doom, but it struggles to maintain playable frame rates beyond that resolution. The Ryzen 7 5800XT has ample processing power to feed this GPU, but the GTX 1650's architectural limits — 896 shading units, 32 ROPs, and 128.1 GB/s bandwidth — define the performance ceiling in this title.
