Doom

The AMD Ryzen 7 5800XT paired with the Intel Arc B370 is a lopsided combination for Doom, where the CPU’s strong multi-threaded and single-threaded scores are held back by a GPU whose benchmark percentile places it near the bottom of the tested pool. In practical terms, this build delivers playable frame rates only at 1080p with reduced settings, while 1440p becomes a compromise and 4K sits below the threshold for smooth action. The measured data shows a clear ceiling imposed by the graphics solution, not the processor.

How This Combo Ranks

The combo rank of 2696 out of 2930 places this pairing in the lower echelon of tested systems for Doom. That is a stark contrast to the CPU’s own standing: the Ryzen 7 5800XT sits at the 81st percentile among all CPUs, meaning it outperforms roughly four out of five processors in general benchmarks. The GPU, however, is at the 5th percentile among all GPUs, which drags the overall combination down sharply. The data suggests that the combo rank is almost entirely dictated by the graphics card’s limitations, as the CPU’s relative strength is neutralized in a game that relies heavily on the GPU for rendering.

Looking at the measured frame rates, the ranking makes sense. At 4K Ultra, the combo only manages 20 FPS, which is unplayable for a fast-paced FPS. Even at 1080p Low, the 96 FPS average is respectable but not exceptional, given that many modern mid-range GPUs would push far higher. The gap between the CPU’s 81st percentile and the combo’s 8th percentile highlights a severe bottleneck: the Arc B370 cannot translate the CPU’s processing power into high frame rates. For context, the CPU’s nearest rivals (Ryzen 7 7840H, 8845HS, 7840HS, and 9600X) all have average scores within 0.6% of the 5800XT, so swapping the CPU for any of those would not change the combo’s fate meaningfully. The GPU’s nearest rivals (ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M) are all over a decade old, underscoring how dated the Arc B370’s performance level is.

In practice, this means the combo is suited for low-resolution, low-detail gaming. The 1080p Low result of 96 FPS is the only measured row that approaches a smooth 60+ FPS experience without any settings compromises beyond the preset. At 1440p, the best case is 62 FPS on Low, which is borderline. At 4K, no settings preset reaches even 40 FPS, making that resolution effectively off-limits. The ranking reflects this reality: it is a pairing that works for esports-style play at 1080p on modest settings, but nothing more demanding.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture, built on a 7 nm process at TSMC. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a 32 MB shared L3 cache and 512 KB of L2 per core. The CPU supports DDR4 memory with dual-channel bandwidth of 51.2 GB/s and operates on the AMD Socket AM4 platform. Its TDP is 105 W, and it has an unlocked multiplier for overclocking.

In benchmark terms, the CPU shows strong scaling across thread counts. The 3dmark results go from 959 single-thread to 1879 at 2 threads, 3603 at 4 threads, 6141 at 8 threads, and 7683 at 16 threads, with max threads slightly lower at 7680. This indicates that the processor efficiently utilizes all 16 threads, which is relevant for Doom since the game can use multiple cores for physics and AI, though it is not heavily multi-threaded. The Cinebench R23 scores of 3359 single-core and 23794 multi-core further confirm balanced performance: the single-core score is high enough for games that rely on one or two threads, while the multi-core result shows 7x scaling, which is solid for a desktop part.

However, the CPU’s role in this combo is largely to feed the GPU. Since the Arc B370 is the limiting factor, the CPU rarely becomes the bottleneck. At 1080p Low, the 96 FPS average is likely CPU-bound in some scenes, but the GPU’s low fill rate and pixel rate (48.00 GPixel/s) cap overall output. The CPU’s 3dmark_16_threads score of 7683 and passmark_multithread score of 28053 indicate it can handle modern game workloads, but the measured FPS data for Doom shows that even at 1080p Low, the combo does not exceed 96 FPS, which is modest for a game from 2016. The CPU’s 81st percentile ranking suggests that if paired with a stronger GPU, this processor could push much higher frame rates, but with the Arc B370, the CPU’s headroom is wasted.

The CPU’s memory bandwidth of 51.2 GB/s is another factor. Since the GPU uses system shared memory, the CPU and GPU compete for the same DDR4 bandwidth. This shared memory architecture means that the GPU’s performance is dependent on system memory speed and latency, which could further limit frame rates. The data shows that at 4K Medium, the average FPS is 29, and at 4K High it is 25, which indicates that the GPU cannot keep up with the resolution demands, and the shared memory does not help. For a game like Doom, which is well-optimized, the CPU is more than capable, but the combo’s performance is squarely in GPU-led territory.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings presets (Low, Medium, High, Ultra), with average FPS for all rows and min/max FPS for the Medium preset only. Starting at 1080p, the combo achieves 96 FPS on Low, 84 FPS on Medium (min 71, max 96), 71 FPS on High, and 58 FPS on Ultra. This shows a clear progression: dropping from Low to Ultra costs 38 FPS, which is a 40% reduction. The Medium preset has a tight min-to-max range of 71 to 96, indicating consistent frame pacing with only a 25 FPS spread.

At 1440p, the numbers drop significantly. Low settings yield 62 FPS, Medium gives 54 FPS (min 46, max 62), High produces 46 FPS, and Ultra falls to 37 FPS. The gap between Low and Ultra is 25 FPS, a 40% decline from the Low baseline. The Medium preset’s min of 46 FPS suggests occasional dips below the average, which could cause stutter in fast-paced combat. For a game like Doom that demands quick reactions, 46 FPS minimum is on the edge of playability.

At 4K, the combo struggles. Low settings produce 34 FPS, Medium averages 29 FPS (min 25, max 34), High drops to 25 FPS, and Ultra bottoms out at 20 FPS. None of these are remotely playable for a first-person shooter. The Medium preset’s min of 25 FPS would be a slideshow during intense firefights. Even the Low preset at 34 FPS is below the 40 FPS threshold that many players consider the absolute floor for action games.

Comparing resolution scaling, the data shows that moving from 1080p to 1440p reduces FPS by roughly 35-40% across all settings (e.g., 96 to 62 on Low, 84 to 54 on Medium, 71 to 46 on High, 58 to 37 on Ultra). Moving from 1440p to 4K reduces FPS by another 45-50% (62 to 34 on Low, 54 to 29 on Medium, 46 to 25 on High, 37 to 20 on Ultra). This scaling is consistent with a GPU that is heavily bandwidth-constrained, as the system shared memory cannot provide the throughput needed for higher resolutions. The 1080p Medium result of 84 FPS is the best balance of quality and speed, but the 1440p Medium result of 54 FPS (min 46) shows that 1440p is only viable on Low for a consistent 60 FPS experience.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel’s 3 nm process. It has 1280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. Its base clock is 300 MHz, boosting to 2400 MHz, and it uses system shared memory with no dedicated VRAM. The GPU’s pixel rate is 48.00 GPixel/s, and its texture rate is 96.00 GTexel/s, with FP32 performance of 6.144 TFLOPS. The TDP is 25 W, and it is an IGP with no power connectors.

The GPU’s benchmark results are minimal: it only has one recorded test, 3dmark_steel_nomad_dx12, with a score of 1184. That score places it at the 5th percentile among all GPUs, and its nearest rivals are all legacy parts from over a decade ago (ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, AMD FirePro M2000). The deltaPct values show that the Arc B370 is within 1.4% of these ancient cards, meaning its raw performance is comparable to GPUs from 2010-2011. This is a critical finding: the Arc B370 is not a modern gaming GPU by any stretch, despite its Xe3-LPG architecture.

In Doom, this GPU role is decisive. The measured FPS data shows that the GPU cannot handle 4K at all, and even 1440p is marginal. The low pixel rate and texture rate, combined with system shared memory, create a bottleneck that the CPU cannot overcome. The GPU’s boost clock of 2400 MHz is respectable, but with only 20 ROPs and 40 TMUs, the fill rate is limited. The FP32 throughput of 6.144 TFLOPS is low compared to even entry-level discrete GPUs, which explains why the combo struggles to exceed 96 FPS at 1080p Low.

The shared memory architecture is particularly problematic. Since the GPU has no dedicated VRAM, it relies on the system’s DDR4 memory, which has a bandwidth of 51.2 GB/s. This is far below what a discrete GPU would offer, and it means that as resolution increases, the memory bandwidth becomes a severe constraint. The 4K results (20-34 FPS) are consistent with a GPU that is starved for memory bandwidth. The 1080p results are better because the lower resolution requires less memory traffic, but they are still capped by the GPU’s compute and fill rate limits. For a game like Doom, which was designed for GPUs with dedicated VRAM, the Arc B370’s shared memory approach is a major drawback.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and the player’s tolerance for frame rate dips. At 1920x1080, the Low preset delivers 96 FPS, which is the highest measured average across any resolution and setting. However, the Medium preset at 84 FPS (min 71, max 96) offers a significant visual upgrade with only a 12 FPS penalty, and the minimum of 71 FPS ensures that the game stays above 60 FPS even in demanding scenes. The High preset at 71 FPS is also playable, but the Medium preset provides a better balance: it has a 71 FPS minimum, which is smoother than High’s likely lower minimum (though High’s min/max are not recorded). The Ultra preset at 58 FPS is below the 60 FPS threshold, so it is not recommended for consistent action.

At 2560x1440, the choices are more constrained. The Low preset at 62 FPS is the only setting that averages above 60 FPS, but its lack of min/max data means we cannot confirm stability. The Medium preset at 54 FPS (min 46, max 62) shows that frame rates can dip to 46 FPS, which may cause noticeable stutter during combat. For a game like Doom, where smoothness is paramount, the Low preset is the safer choice, though it comes with a visual downgrade. The High preset at 46 FPS and Ultra at 37 FPS are both below the playable threshold for a fast-paced shooter.

At 3840x2160, no settings preset is viable. The Low preset at 34 FPS is the best case, but it is still below 40 FPS, which is generally considered the minimum for a playable FPS experience. The Medium preset at 29 FPS (min 25) is a slideshow, and High (25 FPS) and Ultra (20 FPS) are unplayable. Players with 4K displays should either lower the resolution to 1440p or accept that this combo cannot run Doom at 4K with any playability.

The best overall experience, per the measured rows, is 1920x1080 with Medium settings. This preset delivers 84 FPS average with a 71 FPS minimum and 96 FPS maximum, which provides smooth gameplay while retaining some visual fidelity over Low. The 71 FPS minimum ensures that the game rarely drops below the 60 FPS V-sync threshold, and the 96 FPS maximum shows there is headroom for less demanding scenes. If the player prioritizes maximum frame rate over visuals, 1080p Low at 96 FPS is the clear choice, but the Medium preset offers the best compromise between speed and quality. For 1440p, the Low preset is the only recommendation, and for 4K, the combo should be avoided altogether. In summary, this system is best used at 1080p with Medium or Low settings, and players should not expect to push higher resolutions without significant performance sacrifices.
