Doom

How This Combo Ranks

The combination of the AMD Ryzen 9 9950X3D and the Intel Arc B570 ranks 2332nd out of 2930 tested combos in Doom. This places the pairing in the lower 20th percentile of all tested configurations, indicating that while the hardware is far from obsolete, it does not deliver the kind of top-tier frame rates that would push it into the upper echelons of the database. The rank is a composite measure that weighs both the CPU and GPU contributions, and in this case, the Arc B570's mid-range positioning drags the overall standing down despite the processor's strength.

The CPU itself sits in the 95th percentile against all CPUs, evidence of its high average benchmark score of 75779. Its nearest rivals in the CPU database—the AMD Ryzen 7 PRO 9755, AMD Ryzen 7 PRO 9755X3D, AMD EPYC 8224P, and Intel Core Ultra 9 285—are all within 0.4% of its average score, meaning the 9950X3D is effectively at parity with the fastest desktop processors available. However, the GPU's 65th percentile standing among all GPUs, with an average benchmark score of 20556, creates a significant bottleneck. The Arc B570's nearest GPU rivals include the NVIDIA GeForce RTX 3070 Mobile, Intel Arc A750, NVIDIA Quadro M4000M, and AMD Radeon R9 M390X, with all deltas under 0.5%—so the card is competitive within its own class, but that class is not aligned with the CPU's flagship status.

The net result is a system that is CPU-bound in synthetic workloads but GPU-bound in actual gaming. The combo rank of 2332 out of 2930 suggests that many less expensive CPU pairings achieve better Doom performance simply because they are matched with stronger graphics cards. For a user prioritizing the Ryzen 9 9950X3D's compute capabilities, this pairing works, but for Doom specifically, the data indicates the GPU is the limiting factor.

GPU Role

The Intel Arc B570 is built on the Xe2-HPG architecture, codenamed Battlemage, and fabricated on a 5 nm process at TSMC. It features 2304 shading units, 144 texture mapping units, and 80 raster output units, with 18 ray tracing cores. The GPU operates at a fixed base and boost clock of 2500 MHz, which is a relatively high sustained frequency for a mid-range card. Memory is 10 GB of GDDR6 on a 160-bit bus, yielding a bandwidth of 380.0 GB/s—ample for 1080p and 1440p gaming but potentially strained at 4K with high-detail settings.

In Doom, the GPU's role is evident in the measured FPS scaling across resolutions. At 1080p with Low settings, the Arc B570 pushes 164 FPS, but at 4K with Ultra settings, it falls to 35 FPS. This 4.7x performance drop from the lowest to the highest load is characteristic of a GPU that is not designed for 4K ultra gaming. The card's pixel rate of 200.0 GPixel/s and texture rate of 360.0 GTexel/s suggest it can handle fill-rate-heavy scenes, but the memory bandwidth of 380.0 GB/s becomes a limiting factor at higher resolutions where more data must be streamed per frame.

The GPU's average benchmark score of 20556 places it in the 65th percentile, and its nearest rival, the Intel Arc A750, is within 0.1% of its score—indicating the B570 is a slight step down from its predecessor's performance tier. The 10 GB VRAM is sufficient for Doom at all tested settings, as the game's 2016 release date means it does not require the massive memory pools of modern titles. However, the card's FP32 throughput of 11.52 TFLOPS is modest, and this shows in the 4K results where the GPU is clearly saturated.

Resolution Scaling

The FPS progression from 1080p to 4K reveals a classic GPU-bound scaling pattern. At 1080p with High settings, the combo achieves 121 FPS; at 1440p High, it drops to 78 FPS (a 35.5% reduction); at 4K High, it falls to 42 FPS (a 46.2% reduction from 1440p). This accelerating decline is a hallmark of a GPU that is running out of fill rate and memory bandwidth as pixel count increases.

The Low settings row shows a similar trend but with higher absolute numbers: 164 FPS at 1080p, 106 FPS at 1440p (35.4% drop), and 57 FPS at 4K (46.2% drop). The consistency of these percentage drops across settings indicates that the scaling is resolution-driven rather than setting-driven. The Medium settings row is the only one with min and max FPS data: 1080p Medium shows a min of 121 and max of 164, 1440p Medium shows a min of 79 and max of 106, and 4K Medium shows a min of 43 and max of 58. The min-to-max spread narrows as resolution increases (43 FPS gap at 1080p, 27 FPS at 1440p, 15 FPS at 4K), suggesting that at higher resolutions the GPU is more consistently pegged at its limit, reducing frame-time variance.

The fact that the CPU is not the bottleneck is confirmed by the CPU's multi-threaded capabilities. With 16 cores and 32 threads, the Ryzen 9 9950X3D can easily handle Doom's engine threading, and its 3DMark max-threads score of 17184 indicates substantial headroom. The 1080p Low result of 164 FPS is likely near the GPU's maximum output, not a CPU limitation, as the CPU's single-thread score of 1292 in 3DMark is competitive with top desktop processors.

Settings Recommendations

Based on the measured FPS data, the optimal balance of visual quality and performance for this combo is the Medium preset. At 1080p Medium, the combo delivers 143 FPS with a minimum of 121 FPS, which is well above the 60 FPS threshold for smooth gameplay and provides only a 12.8% reduction from Low settings. At 1440p Medium, the average drops to 92 FPS with a minimum of 79 FPS, still comfortably playable on high-refresh-rate monitors. At 4K Medium, the average falls to 50 FPS with a minimum of 43 FPS, which is borderline but acceptable for slower-paced segments.

High settings are also viable for 1080p and 1440p. At 1080p High, the combo hits 121 FPS, and at 1440p High, it maintains 78 FPS. However, the jump from Medium to High at 4K is from 50 to 42 FPS (a 16% drop), which pushes the experience below the 60 FPS target. Ultra settings are only recommended for 1080p, where the combo achieves 99 FPS, but at 1440p Ultra drops to 64 FPS (near the 60 FPS minimum) and at 4K Ultra falls to 35 FPS, which is not ideal for a fast-paced FPS.

The data suggests that Medium is the sweet spot for this combo, as it offers the best frame-time consistency (as evidenced by the min FPS data) while maintaining high averages. Low settings do provide a significant boost—164 FPS at 1080p, 106 FPS at 1440p, and 57 FPS at 4K—but the visual trade-off is substantial, and the Medium preset's min FPS at 1080p (121 FPS) is still higher than many gamers' display refresh rates.

Measured FPS Breakdown

At 1920x1080, the combo produces its highest frame rates across all settings. Low settings yield an average of 164 FPS, Medium averages 143 FPS with a minimum of 121 and maximum of 164, High averages 121 FPS, and Ultra averages 99 FPS. The progression from Low to Ultra shows a 39.6% performance decrease, which is a relatively gentle curve for a GPU-bound scenario.

At 2560x1440, the results drop proportionally. Low settings average 106 FPS, Medium averages 92 FPS with a minimum of 79 and maximum of 106, High averages 78 FPS, and Ultra averages 64 FPS. The drop from 1080p to 1440p at each setting is consistent: Low drops by 35.4%, Medium by 35.7%, High by 35.5%, and Ultra by 35.4%. This uniformity indicates that the GPU is scaling predictably with pixel count.

At 3840x2160, the performance falls off more steeply. Low settings average 57 FPS, Medium averages 50 FPS with a minimum of 43 and maximum of 58, High averages 42 FPS, and Ultra averages 35 FPS. The drop from 1440p to 4K is steeper than from 1080p to 1440p: Low drops by 46.2%, Medium by 45.7%, High by 46.2%, and Ultra by 45.3%. This non-linear scaling is typical of a GPU that is hitting memory bandwidth limits, as the 380.0 GB/s bandwidth is not sufficient to maintain fill rates at 4K.

The Medium settings row is the only one with complete min and max data across all three resolutions. The min FPS at 1080p (121 FPS) is equal to the average at High settings, indicating that Medium has a stable frame delivery. At 1440p, the min of 79 FPS is close to the High average of 78 FPS, and at 4K, the min of 43 FPS is just above the High average of 42 FPS. This suggests that Medium settings provide a consistent experience that is only slightly below the next quality tier.

FAQ

Q: Is the AMD Ryzen 9 9950X3D overkill for this GPU in Doom?

A: The data indicates yes. The CPU sits in the 95th percentile with a Cinebench R23 multi-core score of 42018, while the GPU is in the 65th percentile. The 1080p Low result of 164 FPS is likely GPU-limited, as the CPU's single-thread performance of 1292 in 3DMark is more than sufficient for Doom's engine.

Q: Can this combo maintain 60 FPS at 1440p?

A: Yes, at Medium and High settings. Medium averages 92 FPS and High averages 78 FPS at 1440p, both well above 60 FPS. Ultra settings average 64 FPS, which is just above the threshold but may dip below in intense scenes.

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

A: 1080p is the sweet spot, as all settings except Ultra deliver over 120 FPS. The 1440p Medium result of 92 FPS is also strong, but 4K is only playable at Low settings (57 FPS) or Medium (50 FPS).

Q: How does the Intel Arc B570 compare to its nearest rival, the Arc A750?

A: The B570 has an average benchmark score of 20556, which is 0.1% lower than the Arc A750's score of 20582. This places the B570 at parity with its predecessor, with a negligible performance delta.

Q: Does the Ryzen 9 9950X3D's 128 MB of L3 cache help in Doom?

A: The CPU's L3 cache is 128 MB, which is large for a desktop processor, but Doom's 2016 engine does not heavily stress cache hierarchies. The CPU's 16 cores and 32 threads are more relevant, and the 3DMark max-threads score of 17184 shows ample headroom.

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

A: The measured average is 35 FPS, which is below the 60 FPS target. This result is consistent with the GPU's 10 GB VRAM and 380.0 GB/s bandwidth, which are not sufficient for 4K ultra in a fast-paced FPS.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Granite Ridge, with a base clock of 4.30 GHz and a boost clock of 5.70 GHz. It features 128 MB of L3 cache, which is a substantial pool for gaming, and supports DDR5 memory with a dual-channel bus and 89.6 GB/s bandwidth. The CPU's 3DMark single-thread score of 1292 and multi-thread score of 17184 place it among the fastest desktop processors, and its Cinebench R23 multi-core score of 42018 reinforces this.

In Doom, the CPU's role is to feed the GPU with enough draw calls and physics calculations to maintain frame rates. The data shows that the CPU is not the bottleneck at any resolution or setting. At 1080p Low, the combo hits 164 FPS, which is likely the GPU's maximum output, not a CPU limit. The CPU's single-thread performance is critical for Doom's engine, which relies on a primary render thread, and the 1292 single-thread score in 3DMark is more than adequate.

The CPU's nearest rivals are all within 0.4% of its average benchmark score, with the AMD Ryzen 7 PRO 9755 being the closest at 0.1% delta. This means that swapping the 9950X3D for a slightly cheaper CPU would not change Doom performance, as the GPU would still be the limiting factor. The CPU's 32 threads are underutilized in Doom, as the game typically uses fewer than 8 threads, but the high boost clock of 5.70 GHz ensures that the primary thread has ample single-core headroom.

The 9950X3D's memory bandwidth of 89.6 GB/s is also not a limiting factor in Doom, as the game's texture streaming is well within this capacity. The CPU's PCIe Gen 5 interface with 24 lanes provides more than enough bandwidth for the Arc B570, which uses a PCIe 4.0 x8 interface. In summary, the CPU is a high-end component that is effectively idle in Doom, and its performance is not the determining factor in the combo's frame rates.
