Roblox

The AMD Ryzen 7 7800X3D and Intel Arc B570 combination delivers a compelling experience in Roblox, with frame rates that comfortably exceed standard display refresh rates across most settings. The data shows a system that scales predictably with resolution, though the relationship between CPU and GPU workloads shifts dramatically depending on the target resolution and quality preset.

Resolution Scaling

The measured FPS data reveals a clear and consistent scaling pattern as resolution increases from 1920x1080 to 3840x2160. At 1080p with Low settings, the system achieves 262 FPS average. Moving to 1440p at the same settings drops this to 175 FPS, and at 4K the average falls to 99 FPS. This represents a 62% reduction in frame rate from 1080p to 4K at Low settings, which indicates a substantial GPU workload increase as pixel count quadruples.

At High settings, the scaling is similarly pronounced. The 211 FPS at 1080p drops to 141 FPS at 1440p, then to 80 FPS at 4K. The 4K result is only 38% of the 1080p figure, confirming that Roblox becomes heavily GPU-bound at higher resolutions. The Ultra preset shows the steepest curve: 171 FPS at 1080p, 114 FPS at 1440p, and just 65 FPS at 4K. At 4K Ultra, the system is clearly rendering near its practical limit for this game.

The Medium preset provides the most complete data with min and max FPS values. At 1080p Medium, the average is 239 FPS with a minimum of 203 and maximum of 275. Moving to 1440p Medium yields 159 FPS average with a 135 FPS minimum and 183 FPS maximum. At 4K Medium, the average drops to 90 FPS, with a minimum of 77 and maximum of 104. The spread between minimum and maximum FPS narrows slightly as resolution increases, suggesting that frame pacing becomes more consistent when the GPU is more fully utilized.

The resolution scaling data indicates that at 1080p, even with the demanding Ultra preset, the system has substantial headroom. The 1080p Ultra result of 171 FPS is still well above the 1440p High result of 141 FPS, which suggests the CPU can feed the GPU adequately at lower resolutions but the GPU becomes the primary constraint as pixel count rises.

CPU Role

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread processor based on the Zen 4 architecture, built on a 5nm process. Its base clock is 4.20 GHz with a boost clock of 5.00 GHz. The processor features a substantial 96 MB of shared L3 cache, which is notable for gaming workloads. Its benchmark scores place it in the 83rd percentile among all CPUs.

The CPU's multi-threaded performance is strong, with a Cinebench R23 multicore score of 16817 and a single-core score of 1713. The Geekbench multicore result is 15610, with a single-core score of 2426. In 3DMark testing, the Ryzen 7 7800X3D scores 7967 in the max threads test and 959 in single-thread, showing balanced scaling across thread counts.

The processor's nearest rivals in terms of average benchmark score include the AMD Ryzen 7 8700G and Intel Core i7-13650HX, both with a 0% delta, and the AMD Ryzen 7 7745HX also at 0% delta. The AMD Ryzen 9 PRO 6950H trails slightly at -0.4%. This clustering indicates the 7800X3D sits at a performance plateau where many processors deliver comparable aggregate results.

In Roblox, the CPU's role appears most significant at 1080p, where frame rates are highest. The 262 FPS result at 1080p Low suggests the game logic and physics simulation can be processed quickly by the 8-core, 16-thread configuration. The large L3 cache likely helps with the game's asset streaming and procedural generation workloads. However, the fact that frame rates drop by roughly 33% when moving from 1080p Low to 1440p Low indicates the GPU is becoming the limiting factor even at lower quality presets.

The boost clock of 5.00 GHz provides strong single-threaded performance, which is relevant for Roblox's main game thread. The 3DMark single-thread score of 959 and Geekbench single-core score of 2426 demonstrate capable per-core performance. Still, the game appears to scale reasonably across cores, as evidenced by the 1080p results maintaining high frame rates even on the Ultra preset at 171 FPS.

GPU Role

The Intel Arc B570 is based on the Xe2-HPG architecture, built on a 5nm process at TSMC. It features 10 GB of GDDR6 memory on a 160-bit bus, providing 380.0 GB/s of bandwidth. The GPU operates at a fixed 2500 MHz clock for both base and boost. Its shading units number 2304, with 144 texture mapping units and 80 render output units. The 18 ray tracing cores support DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6.

The Arc B570's benchmark results place it in the 65th percentile among all GPUs. In 3DMark Steel Nomad DX12, it scores 2649. Geekbench OpenCL and Vulkan scores are 83514 and 96844 respectively. PassMark G3D gives a score of 14195, with a GPU compute score of 7281.

Its nearest rivals in terms of average benchmark score include the NVIDIA GeForce RTX 3070 Mobile at +0.1% delta, the Intel Arc A750 at -0.1%, the NVIDIA Quadro M4000M at +0.4%, and the AMD Radeon R9 M390X at -0.5%. The close clustering around the Arc B570's performance level suggests it competes with last-generation mid-range and mobile high-end parts.

In Roblox, the GPU's role becomes increasingly dominant as resolution increases. The 10 GB VRAM capacity is more than sufficient for this game, as Roblox's texture and geometry workloads are moderate compared to modern AAA titles. The 380.0 GB/s memory bandwidth supports the high frame rates observed at 1080p, where the GPU can output 262 FPS at Low settings.

The fixed 2500 MHz clock speed is notable, as it means the GPU runs at a constant frequency under load. This could contribute to consistent frame pacing, which is supported by the min FPS data at Medium settings. The 4K Medium min of 77 FPS is 85.6% of the average of 90 FPS, while the 1080p Medium min of 203 FPS is 84.9% of the 239 FPS average, showing similar consistency across resolutions.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality settings. At 1920x1080, the system delivers its highest frame rates. Low settings produce 262 FPS average, Medium produces 239 FPS, High produces 211 FPS, and Ultra produces 171 FPS. The Medium preset at 1080p shows a minimum of 203 FPS and maximum of 275 FPS, indicating tight frame pacing.

At 2560x1440, the frame rates remain high but show clear GPU scaling. Low settings deliver 175 FPS average, Medium delivers 159 FPS, High delivers 141 FPS, and Ultra delivers 114 FPS. The Medium preset at 1440p shows a minimum of 135 FPS and maximum of 183 FPS. The gap between Low and Ultra at 1440p is 61 FPS, compared to 91 FPS at 1080p, showing that quality settings have a slightly smaller absolute impact at higher resolutions.

At 3840x2160, the system still produces playable frame rates across all settings. Low settings yield 99 FPS average, Medium yields 90 FPS, High yields 80 FPS, and Ultra yields 65 FPS. The Medium preset at 4K shows a minimum of 77 FPS and maximum of 104 FPS. The difference between Low and Ultra at 4K is 34 FPS, further confirming that the GPU becomes the bottleneck at this resolution.

Comparing settings across resolutions reveals interesting patterns. The percentage drop from Low to Ultra is 34.7% at 1080p, 34.9% at 1440p, and 34.3% at 4K. This consistency suggests that the quality presets affect the GPU workload proportionally regardless of resolution. The absolute frame rate differences are larger at lower resolutions because the baseline performance is higher.

The data shows that the system can maintain 100+ FPS at 1080p and 1440p across all settings, and 60+ FPS at 4K across all settings. The only scenario where frame rates approach the minimum threshold for smooth play is 4K Ultra at 65 FPS, which is still above 60 FPS but leaves less headroom for demanding scenes.
