Doom

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600X is a Zen 3 (Vermeer) part built on TSMC's 7 nm process, packing 6 cores and 12 threads. It runs at a 3.70 GHz base clock and boosts to 4.60 GHz, with a 65 W TDP. The 32 MB L3 cache is shared across the chiplet, and the CPU supports DDR4 memory with dual-channel bandwidth of 51.2 GB/s. For a game like Doom, which is known for being highly optimized and responsive to per-core performance, the 5600X's single-thread strength matters more than its core count.

Benchmark data places this CPU in the 78th percentile among all processors. Its multi-threaded Cinebench R23 score of 18578 and single-core score of 2622 indicate that the 5600X can handle both the game's render thread and background tasks without bottlenecking. In 3DMark, the 16-thread score of 5582 and single-thread score of 917 show a balanced scaling curve; the jump from 2-thread (1793) to 4-thread (3363) is nearly linear, suggesting the Zen 3 architecture extracts good performance even when only a few cores are active.

The nearest rival comparisons confirm this is a well-rounded chip. The 5600X trails the AMD Ryzen 5 5600GT by just 0.3% and the Intel Core i7-10700 by 0.3% in average benchmark score, while it leads the Intel Xeon 6325P by 0.7%. These are negligible differences, meaning the 5600X sits in a competitive sweet spot. For Doom specifically, the 12 threads are more than sufficient; the game's engine doesn't scale beyond a handful of threads, so the 5600X's high per-core throughput is what allows it to push frame rates toward the CPU's ceiling at lower resolutions.

The PassMark single-thread score of 3364 and Geekbench single-core score of 2111 reinforce this: Doom's physics and game logic are largely serial, so a processor that excels in single-threaded tasks will keep the GPU fed. Conversely, the PassMark multi-thread score of 21858 shows that even when the game does spawn background threads, the 5600X has enough headroom to avoid stutters. The data indicates that at 1080p, the CPU is the limiting factor in Ultra settings (220.5 FPS vs. the GPU's capability), but at 4K, the GPU takes over as the constraint.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 Ti is an Ada Lovelace part (AD104 chip) built on TSMC's 5 nm process with 35,800 million transistors. It features 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The core runs at 2310 MHz base and 2610 MHz boost, with memory clocked at 1313 MHz (21 Gbps effective). With 7680 shading units, 240 TMUs, and 80 ROPs, the GPU also includes 60 RT cores and 240 tensor cores. Its FP32 throughput is 40.09 TFLOPS, and the pixel rate is 208.8 GPixel/s.

The GPU sits in the 85th percentile among all graphics cards, with an average benchmark score of 44900. Compared to its nearest rivals, the RTX 4070 Ti is 0.6% behind the RTX 5090 Mobile, 1.5% behind the Intel Arc A730M, and 1.6% behind the AMD Radeon Pro 5500 XT, while leading the AMD Radeon Pro 580 by 1.6%. These are tight margins, indicating the 4070 Ti is a high-tier card even against newer mobile parts.

For Doom, the 12 GB VRAM is more than enough at any resolution, as the game's textures are not particularly demanding. The 504.2 GB/s bandwidth ensures that even at 4K Ultra, texture streaming won't cause hitches. The boost clock of 2610 MHz is critical here: Doom's Vulkan renderer benefits from raw shader throughput, and the 40.09 TFLOPS FP32 figure translates directly to fill-rate capabilities. The 3DMark Steel Nomad DX12 score of 5024 and PassMark G3D score of 31624 show that the GPU is well above average in compute-heavy workloads, which aligns with Doom's particle effects and lighting.

At 4K, the GPU is the clear bottleneck. The measured FPS drops from 127 at Low to 78.1 at Ultra, which is a 38.5% reduction—a typical GPU-bound scaling pattern. The RTX 4070 Ti's 12 GB memory doesn't throttle at any setting, but the 192-bit bus width and 504.2 GB/s bandwidth mean that ultra-high-resolution textures and effects will tax the memory controller. Still, the card maintains playable frame rates even at 4K Ultra (78.1 FPS), which indicates that its ROP count and texture rate (626.4 GTexel/s) are sufficient for this game.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a classic scaling pattern. At 1080p Low, the combo hits 353.1 FPS; at 4K Low, it drops to 127 FPS, a 64% reduction. At High settings, the drop is from 270.3 FPS (1080p) to 97.2 FPS (4K), a 64.1% reduction. This consistent ~64% decrease across settings suggests that the GPU is the limiting factor as resolution increases, while the CPU has enough headroom to maintain high frame rates at lower resolutions.

The delta between settings at the same resolution is also telling. At 1080p, the gap between Low (353.1 FPS) and Ultra (220.5 FPS) is 60.1%, which is substantial. At 4K, the gap between Low (127 FPS) and Ultra (78.1 FPS) is 62.6%. The percentage gap remains nearly constant, which indicates that the GPU is the primary constraint at both ends of the resolution spectrum. If the CPU were the bottleneck, the gap would widen at 1080p as the GPU became less utilized.

Looking at 1440p as a middle ground: Low hits 241.1 FPS, Medium 205.9 FPS, High 175.4 FPS, and Ultra 142.9 FPS. The drop from Low to Ultra is 40.7%, which is smaller than at 1080p (60.1%) but larger than at 4K (38.5%). This non-linear scaling suggests that at 1440p, the system is transitioning from a CPU-bound state (at 1080p Low, where the CPU's 353.1 FPS ceiling may be hit) to a GPU-bound state (at 4K Ultra, where the GPU's 78.1 FPS floor is reached). The data shows that 1080p is the only resolution where the CPU's single-thread performance might cap frame rates, particularly at Low settings where the GPU has less work.

The 4K Medium result of 113.7 FPS versus 4K High's 97.2 FPS shows a 14.5% difference, which is modest. This indicates that the GPU has enough bandwidth and compute to handle medium-quality textures and effects at 4K without major penalties. The 4K Ultra result of 78.1 FPS is the only one that dips below the 100 FPS mark, confirming that 4K Ultra is the most demanding configuration in the dataset.

FAQ

Q: Is the AMD Ryzen 5 5600X a bottleneck for the RTX 4070 Ti in Doom?

A: At 1080p Low, the combo reaches 353.1 FPS, which is likely near the CPU's maximum frame rate ceiling. At 4K Ultra, the GPU produces 78.1 FPS, showing that the CPU has enough headroom to avoid being the limiting factor at higher resolutions. The CPU's single-thread score of 2622 in Cinebench R23 supports this.

Q: How does the RTX 4070 Ti's 12 GB VRAM hold up in Doom?

A: The 12 GB of GDDR6X memory with 504.2 GB/s bandwidth is more than sufficient. Even at 4K Ultra, the measured 78.1 FPS shows no signs of VRAM-related stuttering. The GPU's memory bus width of 192-bit is not a constraint in this game.

Q: What is the best resolution for this combo if I want over 100 FPS?

A: The data shows that 1440p High (175.4 FPS) and 1440p Ultra (142.9 FPS) both exceed 100 FPS easily. Even 4K Medium (113.7 FPS) and 4K High (97.2 FPS) are close to that mark. If you want a guaranteed 100+ FPS experience, 1440p Ultra is safe.

Q: How does this combo compare to the nearest CPU rival in terms of bottleneck risk?

Q: Does the GPU's 285 W TDP require a specific power supply setup?

A: The suggested PSU is 600 W with a 1x 16-pin power connector. The card is dual-slot and measures 285 mm in length. No other power requirements are specified in the data.

Q: Is the RTX 4070 Ti overkill for Doom at 1080p?

A: At 1080p Ultra, the combo hits 220.5 FPS, which is far beyond what any 60 Hz or 144 Hz monitor needs. At 1080p Low, the 353.1 FPS figure is likely CPU-limited. The GPU is better utilized at 1440p or 4K, where the resolution scaling shows a more balanced workload.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data is organized by resolution and settings, with all values being average FPS (no min/max data provided). Here is the full breakdown:

1920x1080:

• Low: 353.1 FPS
• Medium: 319.7 FPS
• High: 270.3 FPS
• Ultra: 220.5 FPS

2560x1440:

• Low: 241.1 FPS
• Medium: 205.9 FPS
• High: 175.4 FPS
• Ultra: 142.9 FPS

3840x2160:

• Low: 127 FPS
• Medium: 113.7 FPS
• High: 97.2 FPS
• Ultra: 78.1 FPS

The pattern is consistent: each step up in settings costs roughly 15-20% of frame rate, and each step up in resolution costs roughly 35-45% of frame rate. The largest single drop is from 1080p Low (353.1) to 1440p Low (241.1), a 31.7% reduction. The smallest drop is from 1440p Medium (205.9) to 4K Medium (113.7), a 44.8% reduction.

The 1080p results show the CPU's influence: the jump from Low (353.1) to Medium (319.7) is only 9.5%, while the jump from High (270.3) to Ultra (220.5) is 18.4%. This suggests that at 1080p, the GPU is not the only factor; the CPU's single-thread performance (917 in 3DMark single-thread) becomes relevant at Low settings where the GPU has less work.

At 1440p, the scaling is more uniform: Low to Medium is 14.6%, Medium to High is 14.8%, and High to Ultra is 18.5%. This indicates a more balanced CPU-GPU workload. At 4K, the GPU dominates: Low to Medium is 10.5%, Medium to High is 14.5%, and High to Ultra is 19.7%. The increasing percentage drop at higher settings at 4K shows the GPU's texture units and ROPs being pushed harder.

The combo ranks 227th out of 1681 tested combinations for this game, placing it in the top 13.5% of all pairings. Given the game's 2016 release date, this is a powerful setup for Doom, with even the lowest 4K result (78.1 FPS) being well above playable thresholds.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience depends on your display's refresh rate and resolution. The data shows that the combo can handle high frame rates at every resolution, but the sweet spot is 1440p.

At 1080p, the Ultra preset (220.5 FPS) is the best choice if you have a 240 Hz monitor. The High preset (270.3 FPS) is unnecessary unless you have a 360 Hz display. The Medium preset (319.7 FPS) and Low preset (353.1 FPS) offer diminishing returns; the visual quality loss is not worth the extra frame rate beyond 270 FPS. For most gamers with 144 Hz or 165 Hz displays, the Ultra preset at 1080p is more than sufficient.

At 1440p, the Ultra preset (142.9 FPS) is the recommended choice. It provides the best visual quality while still exceeding 140 FPS, which is smooth on any high-refresh monitor. The High preset (175.4 FPS) is a good fallback if you prefer even higher frame rates, but the visual difference between High and Ultra in Doom is minimal. The Medium (205.9 FPS) and Low (241.1 FPS) presets are not recommended unless you have a 240 Hz monitor and prioritize frame rate over visuals.

At 4K, the situation is different. The Ultra preset (78.1 FPS) is playable but may feel inconsistent on a 120 Hz display. The High preset (97.2 FPS) is the best balance, offering near-100 FPS with good visuals. The Medium preset (113.7 FPS) is also excellent if you want to ensure a stable frame rate above 110 FPS. The Low preset (127 FPS) is only recommended if you have a 120 Hz or 144 Hz 4K monitor and want to hit the refresh rate ceiling.

The data indicates that the 1440p Ultra preset (142.9 FPS) is the overall best experience for this combo. It delivers the visual quality of the Ultra settings without the steep 4K penalty, and the frame rate is high enough for any gaming monitor. If you have a 4K display, the 4K High preset (97.2 FPS) is the pragmatic pick, as it stays above 90 FPS while preserving most of the graphical fidelity. For competitive play on a 1080p 240 Hz monitor, the 1080p High preset (270.3 FPS) offers the best balance of visual quality and speed, as the Low preset's 353.1 FPS is beyond what most displays can show.
