Steamworld Build

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

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor based on the Zen 3 architecture (Vermeer), manufactured on TSMC's 7 nm process. It operates with a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a TDP of 105 W. The chip features 64 KB of L1 cache per core, 512 KB of L2 per core, and a shared 32 MB L3 cache. Memory support is DDR4 over a dual-channel bus, yielding 51.2 GB/s of bandwidth. The CPU sits on the AMD Socket AM4 platform and supports PCIe Gen 4 with 20 lanes from the processor itself.

In synthetic benchmarks, the 5800XT shows balanced scaling from 2 to 16 threads. The 3DMark results progress from 1,879 points at 2 threads to 3,603 at 4 threads, 6,141 at 8 threads, and 7,680 at max threads. The single-thread score is 959. Cinebench R23 results show 23,794 multi-core and 3,359 single-core. PassMark multi-thread scoring reaches 28,053, with single-thread at 3,535. The processor's average benchmark score is 29,879, placing it in the 81st percentile of all CPUs.

For Steamworld Build, a city builder, the data suggests that thread scaling matters less than sustained single-core performance. The game's measured FPS at 1080p Low reaches 184 FPS, which is high enough that the CPU's single-thread capability (3,535 in PassMark single-thread) is not a bottleneck at lower settings. However, the 8-core/16-thread configuration provides headroom for background simulation tasks common in city builders, where population and infrastructure calculations run concurrently. The 3DMark 16-thread score of 7,683 is nearly identical to the max-thread score of 7,680, indicating the chip is fully utilized at 16 threads without diminishing returns.

Comparing to nearest rivals, the 5800XT is statistically tied with the AMD Ryzen 7 7840H (delta 0%), Ryzen 7 8845HS (delta -0.3%), and Ryzen 7 7840HS (delta -0.3%), while edging the Ryzen 5 9600X by 0.6%. This means the CPU's contribution to frame pacing in Steamworld Build should be consistent with those processors, though the game's measured results will show whether GPU or CPU limits dominate at each resolution.

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

The Intel Arc B580 is built on the Xe2-HPG architecture (Battlemage generation) using TSMC's 5 nm process. The chip, designated BMG-G21, contains 19,600 million transistors on a 272 mm² die. It has 2,560 shading units, 160 texture mapping units, and 80 raster output units, along with 20 ray tracing cores. The GPU clock runs at a fixed 2670 MHz for both base and boost. Memory consists of 12 GB of GDDR6 on a 192-bit bus, delivering 456.0 GB/s of bandwidth. The card supports PCIe 4.0 x8 and has a TDP of 190 W.

In synthetic testing, the B580 produces a 3DMark Steel Nomad DX12 score of 3,068, a Geekbench Vulkan score of 109,672, and OpenCL score of 92,821. PassMark G3D scoring reaches 15,748, with compute at 7,729. The average benchmark score is 23,021, placing the GPU in the 68th percentile of all GPUs.

For Steamworld Build, the GPU's VRAM capacity and bandwidth become relevant at higher resolutions and settings. The 12 GB frame buffer is sufficient for the game's asset loading at 4K Ultra, though the measured FPS at that setting is only 24 FPS. The 456.0 GB/s bandwidth supports texture streaming in a city builder where the camera can zoom from street level to a full city view, requiring rapid changes in rendered detail.

Nearest rivals for the B580 include the AMD Radeon RX 580 2048SP (delta -0.2%), NVIDIA GeForce RTX 2080 (delta 0.6%), RTX 3080 (delta -0.7%), and NVIDIA P106-100 (delta -1%). These deltas are all within 1%, meaning the B580's raw compute is comparable to those cards, but the measured FPS in this game will reflect architectural differences and driver optimization.

The GPU's pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s suggest it can handle fill-rate demands at 1440p, but the 4K Ultra result of 24 FPS indicates the game's highest preset is too demanding for this card's rasterization throughput.

FAQ

Q: What is the best resolution for this combo if the goal is 60+ FPS on High settings?

A: At 2560x1440 with High settings, the measured average FPS is 67, which exceeds 60. At 3840x2160 with High settings, the average drops to 35 FPS. Therefore, 1440p High is the highest resolution that maintains a 60+ FPS average on this preset.

Q: How does the CPU's single-thread performance compare to its multi-thread performance in this game?

A: The CPU's PassMark single-thread score is 3,535, while multi-thread is 28,053. In Steamworld Build, the 1080p Low setting achieves 184 FPS, which is likely CPU-bound. The 3DMark single-thread score of 959 versus 16-thread score of 7,683 shows strong scaling, but the game benefits more from the single-thread capability at lower resolutions.

Q: Is the 12 GB VRAM sufficient for 4K Ultra settings?

A: The 12 GB VRAM is present, but the measured 4K Ultra average FPS is 24, which is unplayable. The bottleneck appears to be GPU compute rather than VRAM capacity, as the 4K Medium setting (47 FPS) and 4K Low (62 FPS) show that reducing settings improves performance substantially without changing VRAM usage.

Q: What frame rates can be expected at 1080p Medium?

A: The measured 1080p Medium average is 141 FPS, with a minimum of 119 FPS and maximum of 162 FPS. This is one of the smoothest experiences available for this combo, providing a wide margin above 60 FPS.

Q: How does this GPU compare to the RTX 2080 in synthetic benchmarks?

A: The B580 has an average benchmark score of 23,021, while the RTX 2080 scores 22,895, giving a delta of 0.6% in favor of the B580. This is within the margin of error, indicating near-identical raw performance.

Q: Does the CPU's 32 MB L3 cache affect game performance?

A: The 32 MB shared L3 cache is part of the Zen 3 design. The 3DMark max-thread score of 7,680 is nearly identical to the 16-thread score of 7,683, suggesting cache utilization is consistent. In-game, the 1080p Low result of 184 FPS indicates the cache is sufficient for the game's working set at that resolution.

How This Combo Ranks

The AMD Ryzen 7 5800XT combined with the Intel Arc B580 ranks 2,781 out of 3,706 tested combos in Steamworld Build. This places the pairing in the bottom quartile of all tested combinations, specifically at the 75th percentile from the top (or 25th percentile from the bottom). The rank reflects that while each component is mid-range in its respective benchmark percentiles (CPU at 81st, GPU at 68th), the game's engine does not favor this pairing as strongly as others.

The 3,706 total combos tested means this pairing is in the lower 925 combinations. The CPU's strength in multi-threaded workloads does not translate to a higher rank in this city builder, likely because the game's frame rate is more dependent on GPU throughput at higher settings and on single-thread CPU performance at lower settings. The CPU's nearest rival, the Ryzen 7 7840H, has an identical average score (delta 0%), suggesting that swapping the CPU would not change the ranking. However, the GPU's nearest rival, the RTX 2080, has a delta of 0.6% in favor of the B580, meaning the GPU is slightly better than its closest competitor.

The rank of 2,781 is notable because the CPU percentile (81) is significantly higher than the GPU percentile (68). This suggests the GPU is the limiting factor in most scenarios, but the measured FPS at 1080p Low (184 FPS) shows the CPU can push high frame rates when the GPU is not stressed. The ranking indicates that for users prioritizing Steamworld Build specifically, other component pairings may yield better results, but the data does not specify which combos rank higher.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target frame rate and resolution. For a 60 FPS target, the following configurations meet or exceed that threshold:

At 1920x1080, all four settings achieve above 60 FPS: Low at 184 FPS, Medium at 141 FPS, High at 105 FPS, and Ultra at 71 FPS. The Ultra preset is the best choice for maximum visual quality while staying above 60 FPS.

At 2560x1440, Low achieves 117 FPS, Medium achieves 89 FPS, and High achieves 67 FPS, all above 60. Ultra drops to 45 FPS, so it should be avoided for smooth gameplay. High is the best balance of quality and performance at this resolution.

At 3840x2160, only Low achieves above 60 FPS with 62 FPS. Medium averages 47 FPS, High averages 35 FPS, and Ultra averages 24 FPS. For 4K, Low is the only playable setting for a 60 FPS experience, though users willing to accept lower frame rates could use Medium.

The data shows a consistent pattern: each settings tier reduces performance by roughly 25-30% from the previous tier. At 1080p, the drop from Low to Medium is 43 FPS, Medium to High is 36 FPS, and High to Ultra is 34 FPS. At 1440p, the drops are 28, 22, and 22 FPS respectively. At 4K, the drops are 15, 12, and 11 FPS. The diminishing absolute drops at higher resolutions indicate the GPU becomes more of a limiting factor as resolution increases.

For the best overall experience, 1440p High provides 67 FPS with good visual fidelity. If the user prioritizes frame rate over visuals, 1080p Ultra at 71 FPS offers high settings with a 71 FPS average. The recommended preset is 1440p High, as it balances the GPU's capabilities with a smooth frame rate.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings levels, with average FPS provided for all twelve combinations. Minimum and maximum FPS are only available for Medium settings across all resolutions.

At 1920x1080, the average FPS ranges from 184 at Low to 71 at Ultra. The Medium setting shows a minimum of 119 and maximum of 162 FPS, with an average of 141. High averages 105 FPS, and Ultra averages 71 FPS. The spread from Low to Ultra is 113 FPS, showing a wide range of performance depending on quality settings.

At 2560x1440, the average FPS ranges from 117 at Low to 45 at Ultra. Medium has a minimum of 76 and maximum of 103 FPS, with an average of 89. High averages 67 FPS. The spread from Low to Ultra is 72 FPS, narrower than at 1080p, indicating the GPU is becoming more of a bottleneck.

At 3840x2160, the average FPS ranges from 62 at Low to 24 at Ultra. Medium has a minimum of 40 and maximum of 54 FPS, with an average of 47. High averages 35 FPS. The spread from Low to Ultra is 38 FPS, the narrowest of all resolutions, confirming the GPU is the primary limiter at 4K.

The Medium settings provide the only min/max data, offering insight into frame time consistency. At 1080p Medium, the average is 141 with a 119-162 range, showing a 43 FPS variance. At 1440p Medium, the average is 89 with a 76-103 range, a 27 FPS variance. At 4K Medium, the average is 47 with a 40-54 range, a 14 FPS variance. The decreasing variance at higher resolutions suggests the GPU's workload becomes more consistent, but the absolute frame rates become less playable.

Resolution Scaling

The FPS drop from 1080p to 1440p to 4K reveals the limiting component in this pairing. At Low settings, the average FPS drops from 184 at 1080p to 117 at 1440p (a 36% reduction) and then to 62 at 4K (a 47% reduction from 1440p). At High settings, the drop is from 105 at 1080p to 67 at 1440p (36% reduction) and then to 35 at 4K (48% reduction from 1440p). At Ultra settings, the drop is from 71 at 1080p to 45 at 1440p (37% reduction) and then to 24 at 4K (47% reduction from 1440p).

The consistent ~36% reduction from 1080p to 1440p across all settings suggests the GPU is the limiting factor even at 1080p, as a CPU-bound scenario would show a smaller drop when resolution increases. The 1440p to 4K reduction of ~47% is larger, which is expected as the pixel count more than doubles (from 3.7 million to 8.3 million pixels). The relative consistency of these drops across settings indicates that the GPU's rasterization throughput is the primary constraint.

At 1080p Low, the 184 FPS result is high enough that the CPU could potentially push higher if the GPU allowed, but the 36% drop to 1440p suggests the GPU is already limiting at 1080p. The CPU's 3DMark single-thread score of 959 and PassMark single-thread of 3,535 place it in the 81st percentile, which is sufficient for high frame rates. The data indicates that the Intel Arc B580's 13.67 TFLOPS FP32 performance is the bottleneck, as the game's workloads scale more with GPU throughput than CPU thread count.

The scaling pattern also shows that the game is not VRAM-limited, as the 12 GB frame buffer is constant across resolutions but the FPS drops significantly. The 456.0 GB/s memory bandwidth appears adequate, as the FPS drops follow pixel count increases rather than bandwidth saturation. For users wanting to play at 4K, the data suggests that only Low settings (62 FPS) provide a playable experience, while Medium (47 FPS) and above fall below the 60 FPS threshold.
