Roblox

Roblox is a sandbox title that rarely stresses high-end hardware the way modern AAA shooters do, but the measured results for the Intel Core i7-14700F paired with the Intel Arc B390 show a surprisingly wide performance spread across resolutions and settings. The data captures 12 distinct FPS points, ranging from a 42 FPS average at 4K Ultra to a 171 FPS average at 1080p Low, which makes this combo a study in how a powerful CPU can be held back by an integrated GPU.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across every settings preset, indicating that the Intel Arc B390 is the primary bottleneck at higher resolutions. At High settings, the average frame rate falls from 137 FPS at 1920x1080 to 92 FPS at 2560x1440, a 33% reduction, and then further down to 52 FPS at 3840x2160, which is another 43% drop from the 1440p figure. The pattern is even more pronounced at Low settings, where the 1080p average of 171 FPS slides to 114 FPS at 1440p and then to 64 FPS at 4K. This scaling behavior suggests that the Arc B390’s fill rate and shading resources are saturated as pixel count increases, despite the CPU having ample headroom.

Looking at the Medium preset, which includes both average and minimum FPS data, the resolution penalty is clear. At 1080p Medium, the combo averages 155 FPS with a minimum of 132 FPS and a maximum of 179 FPS. Moving to 1440p Medium, the average drops to 104 FPS with a minimum of 88 FPS and a maximum of 119 FPS. At 4K Medium, the average falls to 59 FPS with a minimum of 50 FPS and a maximum of 67 FPS. The minimum FPS values scale proportionally with averages, meaning there is no sudden stutter or frame-time spike introduced at higher resolutions; it is a smooth, predictable decline tied to GPU load.

Ultra settings amplify the resolution sensitivity. The 1080p Ultra average is 111 FPS, which is already 26 FPS lower than High at the same resolution. At 1440p Ultra, the average is 74 FPS, and at 4K Ultra, it collapses to 42 FPS. The gap between High and Ultra at 4K is 10 FPS (52 vs 42), while at 1080p the gap is also 26 FPS (137 vs 111). This indicates that Ultra settings add a nearly constant GPU workload regardless of resolution, but the absolute impact is larger at lower resolutions where the GPU is less likely to be the sole limiter.

The data suggests that for playable frame rates above 60 FPS, this combo is best used at 1080p with any settings up to High, or at 1440p with Low or Medium settings. At 4K, even Low settings only muster 64 FPS, which is technically above 60 but leaves little margin for scene complexity. The limiting component at 4K is clearly the GPU, as the CPU’s 20 cores and 5.40 GHz boost clock are far beyond what Roblox typically requires for physics and game logic.

How This Combo Ranks

In the benchmark database, this specific combination of the Core i7-14700F and Arc B390 ranks 2661 out of 3010 tested combos for Roblox. That places it in the bottom 12% of all configurations, which is a poor showing for a CPU that ranks in the 91st percentile overall. The combo’s rank is dragged down almost entirely by the GPU, which sits in the 9th percentile among all graphics processors.

The CPU’s nearest rivals in average benchmark score include the Intel Xeon 6505P with a score of 53701 and a delta of -0.2%, the Intel Xeon Phi 7290 at 53469 (delta 0.3%), the AMD Ryzen 9 7900X at 53288 (delta 0.6%), and the AMD EPYC 7313P at 53206 (delta 0.8%). The Core i7-14700F’s average benchmark score is 53620, which is within 1% of all four rivals. This tells us that the CPU is performing exactly as expected for its class, but in Roblox, the combo rank suffers because the Arc B390’s nearest rivals are all ancient low-end parts.

The GPU’s nearest rivals are the NVIDIA GeForce GT 520MX with a score of 1463 (delta 1.3%), the NVIDIA GeForce 800M at 1460 (delta 1.5%), the NVIDIA GeForce GT 625 OEM at 1446 (delta 2.5%), and the NVIDIA GeForce GT 710 at 1443 (delta 2.7%). The Arc B390’s average benchmark score is 1482, meaning it outperforms all of these, but they are all entry-level or legacy parts. In Roblox, this GPU class is simply not competitive with modern discrete options, which explains why the combo rank is so low despite the CPU’s strength.

The rank of 2661 out of 3010 is a direct consequence of the GPU bottleneck. If the same CPU were paired with a mid-range discrete GPU, the combo would likely rank much higher because Roblox is not a CPU-intensive title. The data shows that the i7-14700F has a 91st percentile ranking among all CPUs, while the Arc B390 has a 9th percentile ranking among all GPUs, creating a massive imbalance that the game’s engine cannot overcome.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel’s 3 nm process node. It features 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. The base clock is 300 MHz, and the boost clock reaches 2500 MHz. This combination yields a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s, with FP32 performance of 7.680 TFLOPS.

The memory configuration is unusual: the Arc B390 uses “System Shared” memory, meaning it has no dedicated VRAM and instead relies on the system’s main memory. The memory type, bus width, and bandwidth are all listed as “System Shared” or “System Dependent,” which means performance in Roblox will vary based on the host system’s RAM speed and capacity. This is a critical limitation because Roblox, like many games, benefits from dedicated graphics memory for texture streaming and asset loading.

In the measured FPS data, the GPU’s shared memory architecture shows up as a steep performance cliff at higher resolutions. At 1080p Low, the combo reaches 171 FPS, which suggests the GPU can handle the game’s simple geometry and low-resolution textures without needing much memory bandwidth. But at 4K Ultra, the average drops to 42 FPS, likely because the shared memory interface cannot keep up with the demands of 4K textures and effects, even if the shading units are technically capable.

The GPU’s 9th percentile ranking among all GPUs is reflected in the 3DMark Steel Nomad DX12 score of 1482. This is a modest result, and the nearest rivals in the database are all NVIDIA parts from a decade ago. The Arc B390’s 80 W TDP and IGP slot width indicate it is designed for portable or low-power devices, not for high-end gaming. In Roblox, the GPU’s limited ROPS (24) and TMUs (48) become the bottleneck at 1440p and above, as evidenced by the FPS drops between resolutions.

The fact that the Arc B390 has 12 RT cores is irrelevant for Roblox, which does not use ray tracing in its default rendering path. The GPU’s DirectX 12 Ultimate support and Vulkan 1.4 compliance are modern, but the raw throughput is what matters in this game. The 7.680 TFLOPS FP32 figure is respectable for an iGPU, but it is clearly insufficient for 4K gaming in this title, as the 52 FPS High and 42 FPS Ultra results show.

FAQ

Q: What is the best resolution and settings combo for this CPU-GPU pair in Roblox?

A: The data shows that 1920x1080 with High settings delivers 137 FPS average, while 1080p Low reaches 171 FPS. For a 60 FPS target, 1440p Medium achieves 104 FPS, and 4K Low hits 64 FPS. The safest choice for consistent frame rates is 1080p High, as it stays well above 60 FPS with headroom.

Q: Why does the combo rank so low (2661 out of 3010) despite having a strong CPU?

A: The rank is determined by the combined performance in Roblox, and the Intel Arc B390 is the limiting factor. The GPU’s average benchmark score is 1482, placing it in the 9th percentile, while the CPU is in the 91st percentile. The game’s performance is capped by the GPU, dragging the combo rank down.

Q: Is the Intel Arc B390 capable of running Roblox at 4K?

A: It can run at 4K, but only at lower settings. The measured results show 4K Low at 64 FPS, 4K Medium at 59 FPS, 4K High at 52 FPS, and 4K Ultra at 42 FPS. None of these are ideal for competitive play, and only Low settings exceed 60 FPS.

Q: How does the Core i7-14700F compare to its nearest CPU rivals in raw benchmarks?

A: The i7-14700F has an average benchmark score of 53620. Its nearest rivals are the Intel Xeon 6505P (53701, -0.2% delta), Intel Xeon Phi 7290 (53469, 0.3% delta), AMD Ryzen 9 7900X (53288, 0.6% delta), and AMD EPYC 7313P (53206, 0.8% delta). All are within 1% of each other, meaning the CPU is performing as expected.

Q: What memory configuration does the Arc B390 use, and does it affect Roblox?

A: The Arc B390 uses System Shared memory with a System Dependent bandwidth. This means it has no dedicated VRAM and relies on the host system’s RAM. In Roblox, this likely contributes to the steep FPS drops at higher resolutions, where texture memory demands increase.

Q: Can this combo maintain 60 FPS at 1440p with Ultra settings?

A: No. The measured 1440p Ultra average is 74 FPS, which is above 60, but the margin is thin. At 4K Ultra, the average falls to 42 FPS, so the GPU cannot sustain high-end settings at high resolutions.

Measured FPS Breakdown

The measured FPS data for Roblox with the Intel Core i7-14700F and Intel Arc B390 covers four resolutions and four settings presets, providing a complete picture of performance scaling.

At 1920x1080, the lowest resolution tested, the combo performs best. Low settings produce an average of 171 FPS. Medium settings yield 155 FPS average, with a minimum of 132 FPS and a maximum of 179 FPS. High settings drop to 137 FPS average. Ultra settings are the most demanding, with an average of 111 FPS. All 1080p results are above 60 FPS, and even Ultra settings are playable.

Moving to 2560x1440, the performance decreases noticeably. Low settings average 114 FPS, which is a 33% drop from 1080p Low. Medium settings average 104 FPS, with a minimum of 88 FPS and a maximum of 119 FPS. High settings average 92 FPS. Ultra settings average 74 FPS. The 1440p results are all above 60 FPS, but the Ultra preset is getting close to the threshold.

At 3840x2160, the GPU’s limitations become severe. Low settings average 64 FPS, which is just above the 60 FPS mark. Medium settings average 59 FPS, with a minimum of 50 FPS and a maximum of 67 FPS. High settings average 52 FPS. Ultra settings average 42 FPS. Only the Low preset stays above 60 FPS, and even then, the minimum FPS for Medium dips to 50, indicating potential stutter.

The Medium preset is the only one with full minimum and maximum FPS data across all resolutions. At 1080p, the minimum is 132 FPS and the maximum is 179 FPS, showing a 47 FPS spread. At 1440p, the minimum is 88 FPS and the maximum is 119 FPS, a 31 FPS spread. At 4K, the minimum is 50 FPS and the maximum is 67 FPS, a 17 FPS spread. This tightening of the frame time range at higher resolutions suggests that the GPU is consistently running at its limit, rather than experiencing occasional spikes.

CPU Role

The Intel Core i7-14700F is a 20-core, 28-thread processor from the Core 14th Gen series, based on the Raptor Lake architecture. It has a base clock of 2.10 GHz and a boost clock of 5.40 GHz, with a TDP of 65 W. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. This is a desktop-class CPU with a 91st percentile ranking among all processors, and its average benchmark score of 53620 places it just ahead of the AMD Ryzen 9 7900X.

In Roblox, the CPU’s role is largely secondary to the GPU, but the data still shows its influence. The 1080p Low result of 171 FPS suggests that the CPU can feed the GPU with enough draw calls and physics updates to hit high frame rates, but the GPU cannot push past that limit. The 20 cores and 28 threads are far more than Roblox needs, as the game is known to be lightly threaded, but the high boost clock of 5.40 GHz helps with single-threaded performance, which is often the bottleneck in older engines.

The CPU’s nearest rivals in the benchmark database are all server or high-end desktop parts. The Intel Xeon 6505P scores 53701, which is 0.2% higher than the i7-14700F. The Intel Xeon Phi 7290 scores 53469, 0.3% lower. The AMD Ryzen 9 7900X scores 53288, 0.6% lower. The AMD EPYC 7313P scores 53206, 0.8% lower. These deltas are negligible, confirming that the i7-14700F is performing at the expected level for its specifications.

The CPU’s memory support includes DDR4 and DDR5, with a dual-channel memory bus. In a system with system-shared GPU memory, the CPU’s memory controller plays a role in overall performance, but the measured FPS data does not isolate this factor. The CPU’s 33 MB of L3 cache is substantial and helps with game asset caching, but Roblox’s simple blocky geometry means the cache is unlikely to be stressed.

The i7-14700F has a launch MSRP of $359, and it supports PCIe Gen 5 with 16 lanes from the CPU. This is irrelevant for the Arc B390, which uses an IGP bus interface, but it means the CPU has headroom for future discrete GPU upgrades. The CPU’s production status is Active, and it was released on 2024-01-07. In the context of Roblox, the CPU is not the limiting factor; the 52 FPS at 4K High and 42 FPS at 4K Ultra are both GPU-bound results, as evidenced by the fact that lowering settings at the same resolution yields significant FPS gains (e.g., from 52 to 64 FPS between High and Low at 4K).

The measured FPS data shows that the CPU can drive the GPU to its maximum potential. At 1080p Low, the 171 FPS result is likely near the GPU’s ceiling, as the CPU has plenty of headroom. At 1080p Ultra, the 111 FPS average is still high, and the drop from Low to Ultra (60 FPS) is attributable to GPU workload, not CPU limitations. The CPU’s role in this combo is to provide a stable platform that never bottlenecks, which it does admirably, but the Arc B390’s integrated nature caps the overall experience.
