Doom

FAQ

Q: What is the overall performance ranking of the AMD Ryzen 7 5800X + Intel Arc B370 combo in Doom?

A: This combo ranks 2696 out of 2930 tested combinations in Doom, placing it in the bottom 8% of configurations. This is a very low standing, indicating that the system struggles to deliver competitive frame rates in this title.

Q: Does the Intel Arc B370 have dedicated VRAM, and how does that affect Doom?

A: No, the Intel Arc B370 uses "System Shared" memory, meaning it relies on the system's main RAM rather than having its own dedicated VRAM. The memory bandwidth is listed as "System Dependent," and its memory clock is also "System Shared." This shared memory architecture is a significant bottleneck for a demanding FPS like Doom, as the GPU must compete with the CPU for memory resources.

Q: What is the boost clock of the AMD Ryzen 7 5800X?

A: The AMD Ryzen 7 5800X has a boost clock of 4.70 GHz. Its base clock is 3.80 GHz. The CPU's high boost capability is one of its strengths, but the data indicates it is not enough to overcome the GPU's limitations in this specific game.

Q: What is the best average FPS this combo achieves in Doom?

A: The highest average FPS recorded is 96, achieved at 1920x1080 resolution with Low settings. This is the only configuration that approaches a high-refresh-rate experience. All other settings at 1080p yield lower results, with Ultra settings dropping to 58 FPS.

Q: How does the Intel Arc B370 compare to its nearest rival, the ATI Mobility Radeon HD 5570?

A: In the 3DMark Steel Nomad DX12 benchmark, the Intel Arc B370 scores 1184, while the ATI Mobility Radeon HD 5570 scores 1186. The deltaPct is -0.2%, meaning the Arc B370 is 0.2% slower than this rival. This places the Arc B370 in a performance class with older, low-power mobile graphics solutions.

Q: Is the performance data for this combo measured or estimated?

A: The data is measured. The "dataIsMeasured" field is set to true, meaning the FPS figures come from actual testing rather than theoretical calculations or estimations.

GPU Role

The Intel Arc B370 is the primary bottleneck in this configuration. Its performance percentile is extremely low, ranking at just the 5th percentile among all GPUs. The 3DMark Steel Nomad DX12 benchmark score of 1184 confirms its limited capabilities, putting it in the same performance tier as legacy parts like the ATI Radeon HD 5770 (score 1190) and the AMD Radeon HD 7650M (score 1192).

The GPU's specifications paint a clear picture of its limitations. It operates with a base clock of 300 MHz and a boost clock of 2400 MHz, but this is paired with a shared memory system. The memory size, type, and bus width are all "System Shared," and the bandwidth is "System Dependent." This means the GPU does not have its own dedicated VRAM pool, which is a critical disadvantage for a game like Doom that relies heavily on fast texture access and frame buffer operations.

The GPU is based on the Xe3-LPG architecture (Panther Lake chip) and is manufactured on a 3 nm process by Intel. It has 1280 shading units, 40 TMUs, and 20 ROPs. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s. The FP32 compute performance is 6.144 TFLOPS. Despite these modern specifications, the shared memory design severely limits real-world performance. The low TDP of 25 W suggests it is designed for power efficiency rather than high performance, which aligns with its classification as an IGP (Integrated Graphics Processor) with no dedicated power connectors.

In Doom, the GPU's role is decisive. The measured FPS shows a clear ceiling across all resolutions and settings. At 4K, the best average FPS is only 34 (at Low settings), and at 1080p, the best is 96 (at Low settings). These numbers are consistent with a GPU that lacks dedicated memory bandwidth and is therefore unable to feed its shading units fast enough for demanding scenes. The score of 1184 in 3DMark Steel Nomad, compared to rivals with scores in the 1168-1192 range, confirms that this is not a gaming-oriented part.

How This Combo Ranks

The combo of AMD Ryzen 7 5800X and Intel Arc B370 ranks 2696 out of 2930 tested combinations in Doom. This places it in the bottom 8% of all configurations tested. The rank is a direct consequence of the GPU's poor performance, as the CPU is a high-end desktop part.

The CPU alone is a strong performer. It is in the 81st percentile among all CPUs, with an average benchmark score of 29123. Its nearest rivals include the Intel Core Ultra 5 135H (avg score 29093, deltaPct 0.1%), the Intel Xeon Phi 7210 (avg score 29245, deltaPct -0.4%), and the Intel Core i5-13500HX (avg score 29270, deltaPct -0.5%). The AMD Ryzen 5 5600XT (avg score 28940, deltaPct 0.6%) is also close. These rivals are within 0.6% of the 5800X's score, showing that the CPU is competitive with many modern mid-range and high-end processors.

However, the GPU's percentile of 5 places it in the bottom 5% of all GPUs. The combination of a top-tier CPU and a bottom-tier GPU results in a system that is severely imbalanced for gaming. The rank of 2696 out of 2930 reflects this imbalance: the CPU is not the limiting factor, but the GPU drags the entire system down.

In practical terms, this combo ranks below the vast majority of systems tested for Doom. It is not just that the GPU is slow; it is that the GPU is so slow that it negates the advantages of the fast CPU. The measured FPS data confirms this: even at the lowest settings, the system cannot achieve high frame rates, and at higher settings, it falls below playable thresholds.

Measured FPS Breakdown

The measured FPS data for Doom reveals a consistent pattern of performance degradation as resolution and settings increase. Here is the full breakdown:

3840x2160 (4K):

• Low settings: 34 average FPS
• Medium settings: 29 average FPS (min 25, max 34)
• High settings: 25 average FPS
• Ultra settings: 20 average FPS

2560x1440 (1440p):

• Low settings: 62 average FPS
• Medium settings: 54 average FPS (min 46, max 62)
• High settings: 46 average FPS
• Ultra settings: 37 average FPS

1920x1080 (1080p):

• Low settings: 96 average FPS
• Medium settings: 84 average FPS (min 71, max 96)
• High settings: 71 average FPS
• Ultra settings: 58 average FPS

The data shows that the system is only playable at 1080p with Low or Medium settings, where it achieves 96 and 84 FPS respectively. At 1080p High, the average drops to 71 FPS, which is still acceptable for many players, but Ultra settings bring it down to 58 FPS, which may feel less smooth.

At 1440p, the system struggles. Only Low settings achieve an average of 62 FPS, which is borderline playable. Medium settings drop to 54 FPS, High to 46 FPS, and Ultra to 37 FPS. These numbers indicate that the GPU is overwhelmed at this resolution, and the experience is likely to be stuttery or unresponsive in intense scenes.

At 4K, the system is not viable for gaming. The best average FPS is 34 at Low settings, which is below a playable threshold. Medium settings average 29 FPS, High 25 FPS, and Ultra 20 FPS. These frame rates are too low for a fast-paced FPS like Doom.

The minimum and maximum FPS data points are only provided for Medium settings. At 4K Medium, the range is 25 to 34 FPS, showing significant frame time variance. At 1440p Medium, the range is 46 to 62 FPS, and at 1080p Medium, it is 71 to 96 FPS. This variance suggests that the frame pacing is inconsistent, which can make the game feel less responsive even when the average FPS is moderately acceptable.

Resolution Scaling

The FPS scaling from 1080p to 4K is steep and reveals the GPU as the primary limiting component. At Low settings, the average FPS drops from 96 at 1080p to 62 at 1440p and then to 34 at 4K. This is a reduction of 35.4% from 1080p to 1440p and a further 45.2% from 1440p to 4K. In total, the FPS drops by 64.6% from 1080p to 4K at Low settings.

At High settings, the scaling is similar. The average FPS is 71 at 1080p, 46 at 1440p, and 25 at 4K. This is a drop of 35.2% from 1080p to 1440p and a further 45.7% from 1440p to 4K, for a total drop of 64.8% from 1080p to 4K.

At Ultra settings, the average FPS is 58 at 1080p, 37 at 1440p, and 20 at 4K. This represents a drop of 36.2% from 1080p to 1440p and a further 45.9% from 1440p to 4K, for a total drop of 65.5%.

This scaling pattern is characteristic of a GPU that is severely bandwidth-limited. As resolution increases, the demand on memory bandwidth grows quadratically with the number of pixels. Since the Intel Arc B370 relies on system shared memory, it cannot provide the necessary bandwidth to maintain frame rates. The CPU, which is a high-performance 8-core part, is not the limiting factor here; if it were, the FPS would remain more stable across resolutions because the CPU workload does not scale as directly with pixel count.

The steep drop off (over 60% reduction from 1080p to 4K) indicates that the GPU is saturated at 1080p and simply cannot keep up with the increased pixel throughput at higher resolutions. This is further evidence that the system is fundamentally GPU-bound in Doom.

CPU Role

The AMD Ryzen 7 5800X is a high-end desktop processor with 8 cores and 16 threads. It is based on the Zen 3 architecture (codenamed Vermeer) and is manufactured on a 7 nm process by TSMC. The base clock is 3.80 GHz, and the boost clock is 4.70 GHz. The CPU has a 32 MB L3 cache, with 512 KB L2 cache per core and 64 KB L1 cache per core.

In synthetic benchmarks, the 5800X shows strong single-threaded and multi-threaded performance. It scores 15476 in Cinebench R23 multicore and 1574.5 in Cinebench R23 single-core. In Geekbench, it scores 11036 multi-core and 2032 single-core. The 3DMark results show 7586 for 16 threads and 7578 for max threads, indicating good scaling. The PassMark multithread score is 27732, and the single-thread score is 3445.

The CPU's percentile of 81 among all CPUs confirms its strong standing. Its average benchmark score of 29123 is closely matched by rivals like the Intel Core Ultra 5 135H (29093) and the Intel Core i5-13500HX (29270), with deltas of just 0.1% and -0.5% respectively. This shows that the 5800X is a competitive CPU even against newer mobile parts.

However, in Doom, the CPU's role is secondary. The measured FPS is consistently low across all resolutions, and the scaling pattern shows that the GPU is the bottleneck. The CPU is not preventing higher frame rates; rather, the GPU cannot deliver them. For example, at 1080p Low, the system achieves 96 FPS, which is likely close to the GPU's maximum capability. If the CPU were the bottleneck, we would expect to see similar FPS across different resolutions, but we see a significant drop as resolution increases, which is a GPU signature.

The 5800X has enough processing power to handle Doom's game logic and physics at high frame rates. Its 8 cores and 16 threads, combined with a 4.7 GHz boost clock, are more than sufficient for this title. The data shows that the CPU is not the limiting factor in this combo; the Intel Arc B370 is.
