Revolution Idle

The Intel Core i7-13700K paired with the Intel Arc B390 produces a fundamentally GPU-limited experience in Revolution Idle, with frame rates collapsing as resolution climbs. Across all settings, the jump from 1920x1080 to 3840x2160 cuts average FPS by roughly 66% to 69%, indicating the Arc B390 cannot sustain the pixel throughput demanded at 4K. The data shows a clear pattern: at 1080p, the i7-13700K has enough headroom to push the Arc B390 to its limits, but at 1440p and beyond, the GPU becomes the sole bottleneck, with CPU performance playing a negligible role in the final frame output.

The Arc B390’s 3DMark Steel Nomad score of 1482 places it in the 9th percentile of all GPUs, a staggeringly low figure that explains the sub-60 FPS results even at 1080p. Its nearest rivals — the GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — all sit within 1.3% to 2.7% of its score, confirming that this is entry-level integrated graphics territory. The B390’s 7.680 TFLOPS FP32 compute and 60.00 GPixel/s pixel rate are technically present, but they translate into real-world performance that struggles to maintain smooth frame rates in an idle game, which is typically not demanding. The measured FPS data shows the bottleneck is almost entirely the GPU, not the CPU.

Resolution Scaling

The scaling behavior from 1080p to 4K is revealing. At 1920x1080 with Low settings, the system achieves 62 FPS, which is the only measured configuration to cross the 60 FPS threshold. Dropping to 2560x1440 Low yields 39 FPS, a 37% reduction, and at 3840x2160 Low, the frame rate falls to 21 FPS, a further 46% drop. This nonlinear scaling — 62 to 39 to 21 — indicates that the Arc B390’s memory bandwidth (labeled "System Dependent" and shared with the system) becomes increasingly constraining as resolution increases, since the GPU must access more data per frame without dedicated VRAM.

For Medium settings, the pattern is similar but with lower absolute values. The 1080p Medium average of 47 FPS (with a min of 40 and max of 54) drops to 30 FPS at 1440p, and then to 16 FPS at 4K (min 13, max 18). The frame time variance also increases at higher resolutions — the 4K Medium range of 13-18 FPS shows a 38% spread between min and max, suggesting that the shared memory subsystem causes intermittent stalls. High settings follow the same trajectory: 45 FPS at 1080p, 28 FPS at 1440p, and 15 FPS at 4K. Ultra settings are the most punishing, with 29 FPS at 1080p, 18 FPS at 1440p, and just 9 FPS at 4K.

The resolution scaling data points to a GPU that is severely underpowered for this game’s rendering demands, even though Revolution Idle is an idle genre title. The i7-13700K, with its 16 cores and 24 threads, is not the limiting factor — the CPU’s 3DMark multi-threaded scores (10717 for 16 threads, 12412 for max threads) and Cinebench R23 multicore result of 30745 are far beyond what this game requires. Instead, the Arc B390’s 24 ROPs and 48 TMUs, combined with its shared memory architecture, create a situation where every resolution increase has a disproportionate impact on FPS. The data indicates that 1080p is the only viable resolution for playable frame rates, and even there, only Low settings achieve 60 FPS.

GPU Role

The Intel Arc B390’s specifications paint a clear picture of its capabilities. With 1536 shading units, 48 TMUs, and 24 ROPs, it offers a compute configuration that is modest by modern standards. Its base clock of 300 MHz and boost clock of 2500 MHz show a wide dynamic range, but the sustained performance in Revolution Idle reflects the lower end of that spectrum under load. The GPU’s 12 RT cores and DirectX 12 Ultimate support are largely irrelevant for this title, as the game’s idle mechanics do not leverage ray tracing or advanced DX12 features. The 7.680 TFLOPS FP32 figure is the theoretical peak, but the measured FPS suggests real-world efficiency is poor.

The most critical aspect of the B390 is its memory configuration: "System Shared" size, type, bus width, and bandwidth. This means the GPU relies on the system’s DDR4 or DDR5 memory via the i7-13700K’s dual-channel controller, rather than having dedicated VRAM. The "System Dependent" bandwidth is a direct consequence — performance varies based on the host system’s memory speed and latency. In this benchmark configuration, the shared memory creates a bottleneck that becomes more pronounced at higher resolutions, where the GPU needs to access larger textures and buffers. The 4K Medium result of 16 FPS, compared to 47 FPS at 1080p Medium, illustrates how severely the shared memory limits scaling.

The 3DMark Steel Nomad score of 1482 is the only GPU benchmark in the data, and it places the B390 in the 9th percentile. Its nearest rivals — the GT 520MX (1463, 1.3% faster), GeForce 800M (1460, 1.5% faster), GT 625 OEM (1446, 2.5% faster), and GT 710 (1443, 2.7% faster) — are all legacy or entry-level parts from over a decade ago. This context is essential: the B390 is not merely a low-end GPU; it is at the absolute bottom of the performance spectrum, competing with parts that were never designed for modern gaming. The 80 W TDP and IGP slot width confirm that this is an integrated solution, not a discrete card, which explains its limited thermal and power headroom.

FAQ

Q: Why does the frame rate drop so dramatically from 1080p to 4K?

A: The Arc B390’s shared memory architecture ("System Shared" bandwidth) becomes the primary bottleneck at higher resolutions. The data shows a 66% FPS drop from 1080p Low (62 FPS) to 4K Low (21 FPS), and a similar 69% drop for Medium settings (47 to 16 FPS), indicating the GPU cannot access data fast enough at 4K pixel counts.

Q: Is the Intel Core i7-13700K holding back performance in this game?

A: No. The CPU’s benchmark scores — Cinebench R23 multicore of 30745 and Geekbench multicore of 19429 — are far above what Revolution Idle requires. The GPU’s 9th percentile ranking and the consistent FPS patterns across resolutions point to the Arc B390 as the sole limiting component.

Q: What is the best settings preset for 1920x1080?

A: Low settings at 1080p produce 62 FPS, the only measured configuration to exceed 60 FPS. Medium settings yield 47 FPS (min 40, max 54), which is still playable but noticeably lower. For a smooth experience, Low is the recommended preset at 1080p.

*Q: Can this system handle 2560x1440 gaming in Revolution Idle?*

A: Only at Low settings, which produce 39 FPS. Medium drops to 30 FPS, High to 28 FPS, and Ultra to 18 FPS. None of these configurations reach 60 FPS, so 1440p is not recommended for a fluid experience, though Low may be acceptable for less demanding play.

Q: How does the Arc B390 compare to its closest competitors?

A: The B390’s 3DMark Steel Nomad score of 1482 is 1.3% behind the GT 520MX, 1.5% behind the GeForce 800M, 2.5% ahead of the GT 625 OEM, and 2.7% ahead of the GT 710. These deltas are negligible, meaning performance is essentially equivalent to decade-old entry-level GPUs.

Q: Why do Ultra settings only achieve 9 FPS at 4K?

A: Ultra settings at 3840x2160 place the maximum load on the Arc B390’s shared memory and 24 ROPs. The 9 FPS average is the lowest measured result, reflecting that the GPU’s pixel throughput (60.00 GPixel/s theoretical) is insufficient for 4K Ultra rendering, even for an idle game.

Measured FPS Breakdown

At 1920x1080, the measured FPS values show a clear hierarchy across presets. Low settings deliver 62 FPS, the highest of any configuration in the dataset. Medium settings average 47 FPS, with a minimum of 40 and maximum of 54 FPS, indicating some frame pacing variability. High settings produce 45 FPS, nearly matching Medium, which suggests that the game’s High preset adds minimal GPU load beyond Medium. Ultra settings drop to 29 FPS, a 38% reduction from Low, showing that Ultra’s additional effects and draw distance significantly impact the B390.

At 2560x1440, the same ordering persists but with lower absolute values. Low settings average 39 FPS, Medium averages 30 FPS (min 25, max 34), High averages 28 FPS, and Ultra averages 18 FPS. The gap between Low and Medium is 9 FPS (23%), while the gap between High and Ultra is 10 FPS (36%). This suggests that Ultra’s additional settings are disproportionately more expensive at 1440p than at 1080p, where the Low-to-Ultra gap was 33 FPS (53%).

At 3840x2160, the results are uniformly poor. Low settings produce 21 FPS, Medium averages 16 FPS (min 13, max 18), High averages 15 FPS, and Ultra averages 9 FPS. The difference between Low and High is only 6 FPS, while Medium and High are within 1 FPS of each other. This compression of results at 4K indicates that the GPU is so severely bandwidth-limited that settings changes have minimal impact — the bottleneck is the shared memory system, not the rendering workload. The Ultra 9 FPS result is the lowest in the dataset, confirming that 4K is not a viable resolution for this combo.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on Raptor Lake architecture, built on Intel’s 10 nm process. Its base clock of 3.40 GHz and boost clock of 5.40 GHz provide substantial single-thread performance, evidenced by a Cinebench R23 single-core score of 2116 and a Geekbench single-core score of 2529. In multi-threaded workloads, the CPU achieves a Cinebench R23 score of 30745 and a Passmark multithread score of 45887, placing it in the 89th percentile of all CPUs. This is a high-end desktop processor that is unequivocally not the bottleneck in Revolution Idle.

The CPU’s nearest rivals in the benchmark database — the AMD Ryzen 9 5900 (46971 avg, 0.2% faster), AMD Ryzen AI 9 HX PRO 375 (47022 avg, 0.3% faster), AMD Ryzen 9 7845HX (46654 avg, 0.5% slower), and Intel Xeon w3-2535 (46653 avg, 0.5% slower) — all have near-identical average scores. This indicates that the i7-13700K’s performance is well within the expected range for its class, and any of these CPUs would produce identical FPS results in Revolution Idle given the same GPU.

The game’s idle genre mechanics mean that CPU load is minimal — there are no complex physics simulations, no large-scale AI, and no intricate particle systems. The i7-13700K’s 30 MB of shared L3 cache and 2 MB per-core L2 cache provide ample bandwidth for the game’s data structures. The CPU’s Passmark integer math score of 154446 and floating-point math score of 114867 are far beyond anything this game would require. In this context, the CPU’s role is to feed the GPU with draw calls and manage game logic, which it does with negligible impact on frame rates. The measured FPS data confirms that swapping the i7-13700K for a much weaker CPU would likely produce identical results, as the Arc B390 is the limiting factor at every resolution and settings combination.

Settings Recommendations

For 1920x1080, the data clearly indicates that Low settings are the only viable choice for a smooth experience, delivering 62 FPS. Medium settings at 47 FPS are playable but not ideal, and the 40 FPS minimum could cause noticeable stutter in fast-paced sections. High settings at 45 FPS offer no meaningful advantage over Medium, while Ultra at 29 FPS is too choppy for comfortable play. The recommendation is to use Low settings at 1080p for the best balance of performance and playability, as the visual upgrade from Low to Medium does not justify the 24% FPS reduction.

At 2560x1440, no preset achieves 60 FPS, and the highest result is Low at 39 FPS. Medium at 30 FPS (min 25) and High at 28 FPS are both below the threshold for smooth gameplay. The data suggests that 1440p is not a recommended resolution for this combo, but if forced to choose, Low settings provide the least compromised experience. The 39 FPS average is borderline playable for an idle game, where frame rate sensitivity is lower than in action titles. Ultra at 18 FPS is not recommended under any circumstances.

At 3840x2160, all presets are effectively unplayable. Low at 21 FPS, Medium at 16 FPS, High at 15 FPS, and Ultra at 9 FPS all fall well below the 30 FPS minimum threshold for acceptable performance. The data shows that even Low settings at 4K are 71% slower than Low at 1080p. For users who must run at 4K, the only option is to accept severely compromised performance, but the recommendation is to avoid 4K entirely with this GPU. The best experience is achieved at 1080p Low, where the system produces 62 FPS — the only configuration that approaches the 60 FPS target. This preset also has no reported minimum FPS, suggesting stable frame delivery, whereas Medium at 1080p has a 40 FPS minimum that could cause occasional hitches.
