Roblox

The AMD Ryzen 7 7700 and AMD Radeon RX 6700 XT combination delivers frame rates that place it solidly in the middle of the database for Roblox, ranking 1940th out of 3711 tested combos. This pairing of an 8-core Zen 4 processor with a 12 GB RDNA 2 graphics card produces results that are consistently playable across all tested resolutions and settings, though the data reveals a clear pattern of the GPU becoming the primary constraint as resolution climbs. The measured performance ranges from a high of 368 FPS at 1080p Low to a low of 91 FPS at 4K Ultra, showing that this combo has enough headroom for high-refresh monitors at lower resolutions while still maintaining playable rates at 4K.

How This Combo Ranks

The combo holds the 1940th position out of 3711 tested combinations, placing it just past the midpoint of the database. This rank reflects a balanced pairing where neither component dramatically outperforms the other in the context of Roblox. The CPU sits in the 87th percentile among all processors tested, which is a strong showing for a desktop part, while the GPU lands in the 72nd percentile among all graphics cards. The gap between these percentiles suggests the system is slightly CPU-heavy in its composition, but the measured frame rates indicate that Roblox does not heavily tax either component at most settings.

When examining the CPU's nearest rivals, the Ryzen 7 7700 produces an average benchmark score of 40081, which is nearly identical to the AMD Ryzen AI 9 365 at 40048, a delta of just 0.1 percent. The Intel Core 5 221E scores 40144, putting it 0.2 percent ahead of the 7700, while the AMD Ryzen 9 270 scores 40246, a 0.4 percent advantage. The Intel Core i9-13905H leads this group with 40313, representing a 0.6 percent edge. These tiny margins mean the 7700 is essentially tied with several mobile and desktop parts in raw compute, so its ranking in Roblox comes down more to how the game uses the available threads.

For the GPU, the RX 6700 XT averages 27425 in benchmark scores, placing it directly alongside the NVIDIA GeForce RTX 4070 Mobile, which scores 27435 with a 0 percent delta. The NVIDIA GeForce RTX 3090 scores 27565, which is 0.5 percent higher, while the AMD Radeon Pro Vega 20 scores 27839, a 1.5 percent lead. The NVIDIA RTX PRO 4000 Blackwell trails at 27135, a 1.1 percent deficit. This grouping shows the RX 6700 XT performing in line with some much larger and more expensive GPUs, which bodes well for its Roblox performance where the workload is not particularly demanding.

CPU Role

The Ryzen 7 7700 is built on the Zen 4 architecture using a 5 nm process from TSMC, featuring 8 cores and 16 threads. It has a base clock of 3.80 GHz and a boost clock of 5.30 GHz, with a 65 W TDP that marks it as a highly efficient desktop part. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache, which provides ample fast memory for game logic and physics calculations. Memory support is DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth, and the CPU includes integrated Radeon Graphics, though the discrete RX 6700 XT handles all rendering duties in these tests.

In Roblox, the CPU's role is significant because the game often relies on single-thread performance for scripting and world simulation. The 7700 scores 1049 in 3DMark single-thread testing and 1930 in Cinebench R23 single-core, which are respectable but not class-leading numbers. More important is the multithreaded capability: the 3DMark 16-thread score of 8484 and Cinebench R23 multicore score of 18760 show that the processor can handle heavy parallel workloads, but Roblox rarely scales to use all 16 threads. The 3DMark 2-thread score of 2043 and 4-thread score of 3931 indicate that the CPU's performance with a few active threads is strong enough to avoid bottlenecking the GPU at lower resolutions.

The benchmark results show the 7700 outperforming its nearest rivals by very small margins. Its average benchmark score of 40081 is within 0.6 percent of the Intel Core i9-13905H and within 0.4 percent of the AMD Ryzen 9 270. This means that in Roblox, where the CPU is not the primary bottleneck at most settings, the 7700 provides more than enough compute headroom. The processor's 87th percentile ranking among all CPUs reinforces that it is a high-end part that will not limit frame rates in this game, even when paired with a GPU that also ranks well.

GPU Role

The Radeon RX 6700 XT uses the Navi 22 chip built on RDNA 2.0 architecture with a 7 nm process from TSMC. It packs 17,200 million transistors into a 335 mm² die, with 2560 shading units, 160 texture mapping units, and 64 render output units. The GPU has 40 ray tracing cores, though Roblox does not heavily utilize ray tracing in its default rendering paths. The memory subsystem consists of 12 GB of GDDR6 on a 192-bit bus, delivering 384.0 GB/s of bandwidth, which is ample for the textures and geometry typical of Roblox worlds.

Clock speeds are set at a base of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz, with memory running at 2000 MHz or 16 Gbps effective. The GPU achieves a pixel rate of 165.2 GPixel/s and a texture rate of 413.0 GTexel/s, with FP32 performance of 13.21 TFLOPS. Power draw is rated at 230 W with a suggested power supply of 550 W, and the card connects via PCIe 4.0 x16. The 12 GB frame buffer is particularly relevant for Roblox because user-generated content can sometimes have large texture sets, though the measured frame rates suggest the VRAM is rarely stressed.

In benchmark terms, the RX 6700 XT scores 19786 in PassMark G3D and 93500 in Geekbench Vulkan, with a PassMark GPU compute score of 9336. Its 72nd percentile ranking among all GPUs places it in the upper midrange, and its average benchmark score of 27425 is essentially identical to the NVIDIA GeForce RTX 4070 Mobile. The GPU is also within 1.5 percent of the Radeon Pro Vega 20 and within 0.5 percent of the RTX 3090, which are much larger cards. This suggests the RX 6700 XT punches above its weight class, and in Roblox, it provides sufficient rendering power to maintain high frame rates even at 4K.

Measured FPS Breakdown

The measured frame rates show a clear hierarchy across resolutions and settings. At 1920x1080, the combo delivers an average of 368 FPS on Low settings, 335 FPS on Medium, 296 FPS on High, and 240 FPS on Ultra. The Medium preset recorded a minimum of 285 FPS and a maximum of 386 FPS, indicating consistent frame pacing even during intense scenes. These numbers show that at 1080p, the system is rarely constrained by either component, with even the most demanding Ultra preset staying well above 200 FPS.

Moving to 2560x1440, the averages drop but remain impressive. Low settings produce 246 FPS, Medium yields 224 FPS with a minimum of 190 FPS and maximum of 257 FPS, High delivers 198 FPS, and Ultra still manages 160 FPS. The drop from 1080p to 1440p is roughly 25-30 percent across settings, which is a modest reduction given the 78 percent increase in pixel count. This indicates that the GPU is beginning to take on more work, but the CPU still has enough headroom to feed it effectively.

At 3840x2160, the frame rates become more moderate. Low settings produce 139 FPS, Medium delivers 127 FPS with a minimum of 108 FPS and maximum of 146 FPS, High drops to 112 FPS, and Ultra falls to 91 FPS. These numbers remain playable for most users, with even the heaviest preset staying above 90 FPS. The gap between Low and Ultra at 4K is 48 FPS, which is the largest spread across all resolutions, showing that the GPU is the limiting factor at this point. The Medium preset at 4K provides the only recorded minimum and maximum values in the dataset, with a 108 FPS minimum that suggests occasional dips but no severe stuttering.

Resolution Scaling

The scaling from 1080p to 4K reveals how the workload shifts between CPU and GPU. At 1080p High, the combo produces 296 FPS, while at 1440p High it drops to 198 FPS, a 33 percent reduction. Moving to 4K High yields 112 FPS, which is another 43 percent drop from 1440p. This progressive decline is steeper than the pixel count increase would suggest, indicating that the GPU is becoming more saturated as resolution rises. The CPU, with its strong single-thread and multithread performance, is able to maintain its end of the bargain even at 1080p where frame rates exceed 300 FPS.

Looking at Low settings, the scaling pattern is similar but with higher absolute numbers. The 368 FPS at 1080p Low falls to 246 FPS at 1440p, a 33 percent drop, and then to 139 FPS at 4K, a 43 percent drop from 1440p. The consistency of these percentage drops across settings suggests that the limiting component is scaling predictably with resolution. At 1080p, frame rates above 300 FPS indicate that the CPU is doing most of the heavy lifting, as the GPU has plenty of spare capacity. As resolution increases, the GPU's fill rate and memory bandwidth become more critical, and the frame rate begins to reflect the RX 6700 XT's capabilities.

The transition from 1080p to 1440p is particularly telling. At 1080p Ultra, the combo delivers 240 FPS, while at 1440p Ultra it drops to 160 FPS, a 33 percent reduction. This is a significant drop, but the absolute numbers remain high enough for smooth gameplay. At 4K Ultra, the 91 FPS average represents a 62 percent drop from 1080p Ultra, which is a substantial decline but still leaves the combo above 90 FPS. The data suggests that the RX 6700 XT is the limiting component at 4K, while the Ryzen 7 7700 has enough headroom to push higher frame rates at 1080p and 1440p.

Settings Recommendations

For users with a 1080p monitor, the Ultra preset at 240 FPS is the best choice for visual fidelity without sacrificing competitive frame rates. The drop from 368 FPS on Low to 240 FPS on Ultra is significant, but 240 FPS is still well above the refresh rate of most gaming monitors. The Medium preset at 335 FPS offers a middle ground for those who prioritize frame rate over visuals, and the 285 FPS minimum ensures that even the most demanding scenes remain fluid. At 1080p, the Ultra preset is recommended because the CPU and GPU have enough headroom to absorb the extra load without noticeable stuttering.

At 1440p, the High preset at 198 FPS provides the best balance of image quality and performance. The Ultra preset at 160 FPS is also viable, especially for users with 144 Hz monitors, but the 38 FPS difference between High and Ultra may not justify the visual gains in a game like Roblox where textures and effects are often simplistic. The Medium preset at 224 FPS is the choice for those who want maximum smoothness, with its 190 FPS minimum ensuring no drops below typical high-refresh thresholds. The Low preset at 246 FPS offers little benefit over Medium given that the difference is only 22 FPS.

At 4K, the Medium preset at 127 FPS is the recommended starting point, as it maintains a comfortable margin above 60 FPS while providing better visuals than Low. The High preset at 112 FPS is also acceptable for users with 60 Hz displays, but the 15 FPS difference between Medium and High may not be worth the reduced headroom. The Ultra preset at 91 FPS is playable but leaves little margin for frame drops, especially in busy Roblox servers with many players and complex builds. The Low preset at 139 FPS is the best option for users who want the highest frame rates at 4K, though the visual compromise is substantial. Given the measured data, the Medium preset at 4K offers the best combination of smoothness and quality, with its 108 FPS minimum and 146 FPS maximum showing consistent performance.
