Fortnite

Fortnite with the AMD Ryzen 7 5700G and NVIDIA GeForce RTX 4080 presents a dataset where the GPU is the dominant performance driver across most settings, but the CPU's capabilities become clearly visible at lower resolutions. The measured frames per second (FPS) show a wide performance envelope, from a demanding 52 FPS at 4K Ultra to a fluid 394 FPS at 1080p Low. This analysis breaks down the measured data to interpret how the resolution and settings affect the balance between the processor and graphics card, and what that means for gameplay.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings presets, which is the primary indicator of where the performance bottleneck lies. At High settings, the average frame rate decreases from 236 FPS at 1920x1080 to 150 FPS at 2560x1440, and finally to 79 FPS at 3840x2160. This represents a 66.5% reduction in frame rate from 1080p to 4K. The scaling is even more dramatic at Low settings, where the average FPS falls from 394 at 1080p to 275 at 1440p, and then to 145 at 4K. The 1080p to 4K drop here is 63.2%.

This pattern is classic for a GPU-bound scenario. As resolution increases, the number of pixels the RTX 4080 must render multiplies, and the workload on the graphics card scales nearly linearly. The fact that the FPS does not remain stable when lowering resolution from 4K to 1080p indicates that the RTX 4080 is the limiting component at all resolutions. If the CPU were the primary bottleneck, we would expect to see the FPS plateau or become very similar between 1080p and 1440p, as the GPU would have spare capacity. Instead, the data shows a clear and consistent increase in FPS as resolution drops, confirming the GPU is doing the heavy lifting.

The scaling between Medium and High settings at the same resolution also shows the GPU's load. At 4K, Medium averages 102 FPS, while High averages 79 FPS, a 22.5% performance hit for the visual upgrade. At 1080p, the difference is 304 FPS for Medium versus 236 FPS for High, a 22.4% difference, showing a similar relative cost. This suggests that the transition from Medium to High adds a consistent level of graphical complexity that the GPU must process, regardless of resolution.

GPU Role

The NVIDIA GeForce RTX 4080 is the clear performance leader in this pairing. Its specifications, including 16 GB of GDDR6X memory on a 256-bit bus with 716.8 GB/s of bandwidth, are more than sufficient for Fortnite's requirements. The GPU's benchmark scores reinforce its high-end positioning, with a PassMark G3D score of 34457 and a percentile ranking of 86 among all GPUs. Its nearest rival, the RTX 4080 SUPER, is only 0.1% faster in average benchmark score, placing this card at the very top of the performance tier.

The GPU's clock speeds are also a factor. With a base clock of 2205 MHz and a boost clock of 2505 MHz, the card is able to maintain high throughput. The data shows that at 1080p Low, the average FPS of 394 is likely near the upper limit of what the game engine can produce efficiently, but it's still the GPU that is pushing those frames. The VRAM capacity of 16 GB is another point in its favor; even at 4K Ultra, there is no indication from the FPS data that memory capacity is a limiting factor, as the card still produces a playable 52 FPS. The performance difference between Low and Ultra at any given resolution is substantial, showing the GPU's raw power is being taxed by the higher graphical fidelity settings.

FAQ

Q: Does the CPU bottleneck the GPU at 1080p?

A: The data suggests the GPU remains the primary bottleneck even at 1080p. The average FPS at 1080p High is 236, and at 1440p High it is 150. If the CPU were the bottleneck, the FPS at 1080p would likely be similar to 1440p, as the CPU would be the limiting factor. Instead, the FPS scales upward as resolution decreases, meaning the GPU is still the component determining the frame rate.

Q: What is the best resolution for this combo to achieve a 144Hz experience?

A: To consistently exceed 144 FPS, 1440p is the appropriate choice. The data shows at 2560x1440 with High settings, the average FPS is 150. At 4K with High settings, the average drops to 79 FPS, which is below the 144Hz threshold. At 1080p, the average FPS is far above 144, but 1440p offers a better balance of visual fidelity and performance.

Q: How much performance is lost when moving from High to Ultra settings?

A: The performance cost is significant. At 1920x1080, the average FPS drops from 236 on High to 156 on Ultra, a 33.9% reduction. At 2560x1440, the average drops from 150 to 99, a 34% reduction. At 3840x2160, it drops from 79 to 52, a 34.2% reduction. The relative cost of Ultra is consistent across resolutions.

Q: Is the 16 GB of VRAM on the RTX 4080 sufficient for Fortnite?

A: Based on the measured FPS, the 16 GB of VRAM is more than adequate. The card is able to produce playable frame rates even at the highest settings of 4K Ultra (52 FPS), and there are no signs in the data, such as sudden frame drops or stuttering, that would indicate memory capacity is being exhausted. The performance scaling is smooth and predictable.

Q: How does the Ryzen 7 5700G's performance compare to its closest rivals?

A: The Ryzen 7 5700G's average benchmark score of 27051 is nearly identical to its nearest rivals. It is 0.2% slower than the Intel Core i9-9900K and 0.4% slower than the Intel Core i5-14400T. It is 0.4% faster than the AMD Ryzen AI 7 445 and 0.6% faster than the Intel Core i7-1370P. This indicates the CPU is a solid mid-range performer, though not a top-tier part.

How This Combo Ranks

In the database of tested combinations, the AMD Ryzen 7 5700G and NVIDIA GeForce RTX 4080 pairing holds a rank of 329 out of 3700 combos. This places it in the top 8.9% of all tested systems, which is a very strong result. The high rank is almost entirely attributable to the GPU's performance, as the CPU's percentile rank of 79 is lower than the GPU's percentile rank of 86.

The rank suggests that this combination is capable of delivering a high-end gaming experience, but it also indicates that the CPU is not the best match for the GPU's potential. When compared to other combos, the RTX 4080 is likely the reason for the high placement, but the Ryzen 7 5700G may prevent the system from reaching the absolute top tier of performance. The data shows that the combo is more powerful than the vast majority of other systems tested, but there is headroom for improvement by pairing the GPU with a stronger processor.

CPU Role

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture. It has a base clock of 3.80 GHz and a boost clock of 4.60 GHz. Its benchmark scores show it to be a capable processor, with a Cinebench R23 multi-core score of 12830.5 and a single-core score of 1494. Its PassMark multithread score is 24419, and it ranks in the 79th percentile of all CPUs.

The CPU's role in Fortnite is to handle game logic, physics, and draw calls. The data suggests that while the CPU is not the primary bottleneck, its performance ceiling is lower than the GPU's. This is most evident when looking at the FPS scaling at 1080p. The 1080p Low average of 394 FPS is a very high number, but it is not as high as the RTX 4080 could theoretically achieve with a faster CPU. The CPU's nearest rivals, such as the Intel Core i9-9900K, have nearly identical average benchmark scores, indicating that this performance level is competitive for its generation but not class-leading. The CPU's 16 MB of L3 cache and dual-channel DDR4 memory support are adequate for the workload, but they don't provide the same performance headroom as the GPU's massive compute resources.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets.

At 1920x1080, the combo is exceptionally fast. The Low preset yields an average of 394 FPS. The Medium preset produces an average of 304 FPS, with a minimum of 259 and a maximum of 350. The High preset averages 236 FPS. The Ultra preset averages 156 FPS.

At 2560x1440, performance remains high. The Low preset averages 275 FPS. The Medium preset averages 194 FPS, with a minimum of 165 and a maximum of 223. The High preset averages 150 FPS. The Ultra preset drops to an average of 99 FPS.

The data shows a clear hierarchy: performance decreases as resolution and settings increase. The Medium preset is the only one with recorded minimum and maximum FPS values, showing a frame time variance of 31 FPS at 1080p, 58 FPS at 1440p, and 31 FPS at 4K.

Settings Recommendations

The optimal settings preset depends on the user's display and performance goals. For a 4K display, the High preset is the best choice for a balanced experience, delivering 79 FPS. The Ultra preset at 4K is only playable at 52 FPS, which may be too low for a competitive shooter. The Medium preset at 4K offers a solid 102 FPS and is a strong alternative if a higher frame rate is desired over maximum visual quality.

For a 1440p display, the High preset is the clear recommendation, as it provides an average of 150 FPS, which is above the 144Hz refresh rate that is common on such monitors. The Ultra preset at 99 FPS is also viable for those who prioritize visual fidelity over a 144Hz experience. The Medium preset at 194 FPS is an option for high-refresh-rate 240Hz displays, though the visual quality is lower.

For a 1080p display, the High preset is again the most balanced, providing 236 FPS, which is well above the refresh rate of most standard monitors. The Ultra preset at 156 FPS is also excellent for high-refresh-rate panels. The Medium preset at 304 FPS is overkill for most displays but can be used for maximum responsiveness on 360Hz monitors. The Low preset at 394 FPS is only recommended for competitive play where every frame matters, as it sacrifices most visual features. The data suggests that High settings offer the best balance of visual quality and performance across all resolutions, being the highest preset that consistently maintains a playable frame rate at 4K.
