# Roblox with Intel Core i7-14700KF + NVIDIA GeForce RTX 4090

The Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 4090 delivers extraordinary frame rates in Roblox, with measured results ranging from 175 FPS at 4K Ultra to 711 FPS at 1080p Low. The combination ranks 144th out of 3,711 tested combos in this game, placing it in the top 4% of all configurations. This analysis examines how the resolution scaling, CPU and GPU characteristics, and measured FPS data define the performance profile of this system.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, but the magnitude of that drop is far smaller than what would typically be observed in more graphically demanding titles. At 1080p Low, the system produces 711 FPS average, while at 4K Low it still manages 268 FPS — a reduction of approximately 62% when moving from 1080p to 4K. This indicates that even at the lowest settings, the render resolution significantly impacts the workload, though the absolute numbers remain exceptionally high.

The scaling from 1440p to 4K is particularly telling. At 1440p High, the system delivers 382 FPS, while 4K High drops to 216 FPS — a 43% reduction. The same settings comparison between 1080p High (572 FPS) and 1440p High (382 FPS) shows a 33% decrease. This progressive scaling suggests that the GPU is becoming more of a limiting factor as resolution climbs, but the RTX 4090's massive compute resources keep the curve relatively shallow compared to what a less powerful GPU would exhibit.

Examining the Ultra preset across all three resolutions provides the clearest view of the scaling behavior. The system achieves 464 FPS at 1080p Ultra, 310 FPS at 1440p Ultra, and 175 FPS at 4K Ultra. The step from 1080p to 1440p Ultra reduces performance by 33%, while the step from 1440p to 4K Ultra reduces it by 44%. The steeper drop at higher resolutions reinforces that pixel throughput becomes increasingly dominant, yet even the lowest 4K Ultra result of 175 FPS remains far above display refresh rate capabilities for most monitors.

The Low preset scaling shows a different character. At 1080p Low the system hits 711 FPS, at 1440p Low it reaches 474 FPS, and at 4K Low it produces 268 FPS. The proportional drops are 33% and 43% respectively, nearly identical to the High preset scaling. This consistency suggests that Roblox's rendering pipeline scales predictably with resolution regardless of graphical complexity settings, and that the RTX 4090's 24 GB GDDR6X memory with 1.01 TB/s bandwidth is never bottlenecked by memory capacity, even at 4K.

What the resolution scaling ultimately indicates is a system that is CPU-bound at lower resolutions and progressively more GPU-bound as resolution rises. The fact that 1080p Low produces 711 FPS while 4K Low produces 268 FPS — a 2.65x difference — while the pixel count increases 4x, points to the CPU's ability to feed the GPU efficiently at lower resolutions, with the GPU's raw throughput becoming the constraining factor only at the highest pixel counts.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process node. Its base clock of 3.40 GHz and boost clock of 5.60 GHz provide substantial single-thread performance, which is critical for Roblox's game engine that typically relies on a limited number of primary threads. The processor's Cinebench R23 single-core score of 6,235 and multi-core score of 44,167 demonstrate its capability, with the multi-core result placing it in the 94th percentile of all CPUs.

The CPU's role in Roblox becomes evident when examining the FPS data at lower resolutions. At 1080p Low, the system achieves 711 FPS, which approaches the practical limits of what game logic and draw call processing can sustain. The fact that increasing resolution to 1440p Low only drops performance to 474 FPS — a 33% reduction — while pixel count increases by 78%, suggests that the CPU is still the primary driver at these settings. The 20-core configuration with 33 MB of shared L3 cache ensures that background tasks and asset streaming do not interfere with the primary game thread.

Comparing to nearest rivals in terms of average benchmark score, the i7-14700KF's overall average score of 70,163 puts it 0.2% ahead of the AMD Ryzen 7 9700F (69,996), 0.4% ahead of the AMD Ryzen 9 7940HX (69,875), and 0.9% ahead of the AMD Ryzen 9 7950X (69,515). It trails the Intel Core Ultra 7 265K by 1% (70,879 vs 70,163). These marginal differences in synthetic benchmarks translate to nearly identical real-world performance in a game like Roblox, where the CPU's single-thread performance and cache hierarchy matter more than raw multi-core throughput.

The processor's memory support for both DDR4 and DDR5, along with dual-channel memory bus, provides flexibility for system builders, though the measured FPS results do not distinguish between memory types. The 125 W TDP and Intel Socket 1700 compatibility make it a mainstream desktop part, and its unlocked multiplier allows overclocking headroom, though the FPS data suggests no overclocking is necessary to achieve the high frame rates measured.

At 4K Ultra, where the system produces 175 FPS, the CPU is clearly not the limiting factor. The RTX 4090's rendering workload at that resolution and settings level dominates the performance profile. The CPU's 28 threads and high boost clock ensure that even with the game's physics and scripting systems, there is no starvation of compute resources. The PassMark multi-thread score of 52,425 and single-thread score of 4,480 reinforce the processor's balanced capability across both single and multi-threaded workloads.

How This Combo Ranks

The combination of the Intel Core i7-14700KF and NVIDIA GeForce RTX 4090 achieves a rank of 144 out of 3,711 tested combinations in Roblox. This places the combo in the top 3.9% of all configurations tested, which is notable given that the RTX 4090 is the flagship consumer GPU and the i7-14700KF is a high-end desktop processor. The high ranking is expected given the hardware's capabilities, but the fact that it is not ranked higher indicates that some combinations — likely those with even more extreme CPUs or configurations optimized for Roblox's specific engine characteristics — outperform it.

The rank of 144 out of 3,711 means there are 143 combinations that produce higher FPS in this game. Given the measured FPS values, which are already exceptionally high, the difference between rank 144 and rank 1 likely represents small incremental gains from CPUs with even higher single-thread performance or systems with more favorable memory configurations. The i7-14700KF's 94th percentile ranking among all CPUs suggests it is near the top, but not at the absolute peak of single-thread performance.

In the context of the GPU's ranking, the RTX 4090 sits in the 88th percentile of all GPUs, with an average benchmark score of 60,347. Its nearest rivals in the GPU benchmark database include the Intel Arc Pro A60 at 60,326 (0% delta), AMD Radeon Pro Vega 48 at 60,140 (0.3% delta), AMD Radeon Pro W6600M at 61,896 (-2.5% delta), and AMD Radeon PRO V710 at 58,657 (2.9% delta). These professional and workstation cards are not typically used for gaming, which means the RTX 4090's consumer-focused architecture and driver optimization likely contribute to its strong performance in Roblox.

The combo's ranking is particularly impressive when considering that Roblox is a game that can be run effectively on integrated graphics. The fact that this high-end combination still ranks in the top 4% suggests that Roblox scales meaningfully with hardware capability, and that the game's rendering engine can utilize the RTX 4090's resources effectively. The 3,711 tested combinations include a wide range of hardware, from entry-level to enthusiast, and this combo's position reflects its performance relative to all others.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. Low settings yield an average of 711 FPS, Medium produces 647 FPS with a minimum of 550 and maximum of 744, High achieves 572 FPS, and Ultra delivers 464 FPS. The gradient from Low to Ultra at 1080p shows a 35% reduction in performance, from 711 to 464 FPS, indicating that the Ultra preset's additional graphical effects impose a meaningful cost even on the RTX 4090.

The 2560x1440 resolution shows a similar pattern with lower absolute values. Low settings produce 474 FPS average, Medium delivers 432 FPS with a range of 367 to 496, High achieves 382 FPS, and Ultra drops to 310 FPS. The scaling from 1080p to 1440p at each setting shows reductions of 33% at Low, 33% at Medium, 33% at High, and 33% at Ultra — remarkably consistent scaling across all settings levels.

At 3840x2160, the frame rates continue to decline. Low settings yield 268 FPS average, Medium produces 244 FPS with a minimum of 208 and maximum of 281, High achieves 216 FPS, and Ultra drops to 175 FPS. The transition from 1440p to 4K shows reductions of 43% at Low, 44% at Medium, 43% at High, and 44% at Ultra. This consistent 43-44% reduction across all settings suggests that pixel count is the dominant factor at this resolution transition.

The Medium preset is the only one with reported minimum and maximum FPS values across all resolutions. At 1080p Medium, the range is 550 to 744 FPS, a spread of 194 FPS. At 1440p Medium, the range is 367 to 496 FPS, a spread of 129 FPS. At 4K Medium, the range is 208 to 281 FPS, a spread of 73 FPS. The narrowing range at higher resolutions indicates that frame time variance decreases as the GPU becomes more consistently loaded.

Comparing the Low and Ultra presets at each resolution reveals the total performance envelope. At 1080p, the gap between Low (711 FPS) and Ultra (464 FPS) is 247 FPS, or 35% of the Low value. At 1440p, the gap narrows to 164 FPS (474 to 310), and at 4K it narrows to 93 FPS (268 to 175). This diminishing absolute gap at higher resolutions suggests that the Ultra preset's additional effects are relatively less impactful when the GPU is already heavily loaded by pixel throughput.

GPU Role

The NVIDIA GeForce RTX 4090 is built on the Ada Lovelace architecture using TSMC's 5 nm process, with 76,300 million transistors on a 609 mm² die. Its base clock of 2235 MHz and boost clock of 2520 MHz, combined with 16,384 shading units, 512 TMUs, and 176 ROPs, provide the raw compute power that drives the high frame rates observed. The GPU's 128 RT cores and 512 tensor cores indicate substantial ray tracing and AI capability, though these features are not typically utilized in Roblox's rendering.

The 24 GB of GDDR6X memory on a 384-bit bus delivers 1.01 TB/s of bandwidth. This memory configuration is far more than Roblox requires, even at 4K resolution, which means the GPU never faces memory capacity or bandwidth constraints in this game. The memory clock of 1313 MHz with 21 Gbps effective speed provides ample throughput for texture streaming and frame buffer operations at the highest settings.

The GPU's FP32 performance of 82.58 TFLOPS and texture rate of 1,290.2 GTexel/s translate directly to the pixel throughput needed for high-resolution rendering. The pixel rate of 443.5 GPixel/s means the GPU can theoretically fill over 443 billion pixels per second, which explains why even 4K Ultra at 175 FPS represents only a fraction of the GPU's maximum capability. The PassMark G3D score of 38,194 places the GPU in the 88th percentile of all GPUs, confirming its high-end positioning.

In Roblox specifically, the RTX 4090's role becomes more significant as resolution increases. At 1080p, the GPU is likely underutilized, with the CPU limiting performance to 711 FPS at Low settings. At 4K, the GPU's workload increases substantially, yet it still delivers 268 FPS at Low and 175 FPS at Ultra. The GPU's DirectX 12 Ultimate support and Vulkan 1.4 compatibility ensure it can handle any rendering API Roblox might employ.

The GPU's average benchmark score of 60,347 places it near the AMD Radeon Pro W6600M (61,896), which is 2.5% higher, and the AMD Radeon PRO V710 (58,657), which is 2.9% lower. These comparisons are based on synthetic benchmarks that may not reflect gaming performance, but they provide context for the GPU's overall compute capability. The RTX 4090's 450 W TDP and triple-slot design indicate its power requirements, though the measured FPS results do not include power consumption data.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p Medium, the system produces 647 FPS average with a minimum of 550 FPS, ensuring smooth gameplay even in demanding scenes. At 1440p Medium, the average of 432 FPS with a minimum of 367 FPS provides ample headroom above typical 144Hz or 240Hz displays. Even at 4K Medium, the 244 FPS average with a 208 FPS minimum exceeds the refresh rate of most high-end monitors.

The High preset is a viable alternative for users who prioritize visual fidelity over maximum frame rates. At 1080p High, the system produces 572 FPS; at 1440p High, 382 FPS; and at 4K High, 216 FPS. These values remain well above 60 FPS even at 4K, making High a reasonable choice for users with 4K displays who want better visual quality without sacrificing smoothness.

The Ultra preset delivers the highest visual quality but at a measurable performance cost. At 1080p Ultra, the system produces 464 FPS; at 1440p Ultra, 310 FPS; and at 4K Ultra, 175 FPS. While these are still excellent frame rates, the 35-44% reduction compared to Low settings may not be worth the visual improvements in a game like Roblox, where the blocky aesthetic does not benefit as much from high-end graphical effects.

For users with high refresh rate displays (240Hz or higher), the Low preset at 1080p or 1440p provides the maximum frame rates. The 711 FPS at 1080p Low and 474 FPS at 1440p Low ensure that the system never becomes the bottleneck, even in the most demanding Roblox experiences. However, the visual quality reduction may be noticeable, so users should consider their display's refresh rate when choosing a preset.

The data indicates that the Medium preset at 1440p provides an optimal balance for most users. The 432 FPS average with a 367 FPS minimum ensures compatibility with even the fastest gaming monitors, while the Medium settings deliver improved visual quality over Low without the performance penalty of High or Ultra. At 4K, Medium is the recommended choice, as it maintains frame rates above 200 FPS while providing better visuals than Low.
