The video analyzes the performance differences between PCIe 3.0, 4.0, and 5.0 when used with the NVIDIA RTX 5090 graphics card, revealing that the performance variations are minimal, typically ranging from 1% to 4%, which most gamers are unlikely to notice. The host emphasizes that while having the latest technology is beneficial for enthusiasts, the average user will not experience significant differences in real-world gaming scenarios.
In the video, the host discusses the performance differences between various PCIe generations (3.0, 4.0, and 5.0) when used with the NVIDIA RTX 5090 graphics card. The main takeaway is that the performance difference between PCIe Gen 5 x16 and PCIe Gen 3 x16 is relatively small, ranging from 1% to 4%, with the 4% difference being noted as significant. The host emphasizes that while these differences exist, they are unlikely to affect the average user significantly, as most gamers won’t notice such minor variations in performance.
The video provides a brief educational segment on how PCIe generations work in relation to motherboards, CPUs, and GPUs. The RTX 5090 is highlighted as the first high-end consumer graphics card that supports PCIe Gen 5, provided that the motherboard and CPU also support it. The host explains that historically, the performance differences between PCIe generations have been minimal, particularly for the first devices on a new generation. They also clarify that PCIe Gen 3 x16 can serve as a rough equivalent to PCIe Gen 4 x8 in terms of bandwidth.
The host goes on to explain the theoretical bandwidth of different PCIe generations and the importance of having matching support across the motherboard, CPU, and GPU to fully utilize the capabilities of PCIe Gen 5. They also note that not all PCIe slots are wired for the maximum number of lanes, which can affect performance. The discussion touches on the limitations of devices themselves, indicating that the device’s capabilities often determine performance more than the PCIe generation.
Benchmark results from various games are presented, showing that the differences in performance across the PCIe generations are minimal. For instance, in games like “Dying Light 2” and “Black Myth: Wukong,” the FPS differences between Gen 3, Gen 4, and Gen 5 were often within a few frames per second, reinforcing the point that for gaming, users are unlikely to notice the slight performance variations. The results suggest that while there are measurable differences, they are not substantial enough to impact the gaming experience for most users.
In conclusion, the host reiterates that the performance differences between PCIe generations for the RTX 5090 are not significant, typically ranging from 1% to 4%. They emphasize that while enthusiasts and high-end gamers may want to ensure they are using the latest technology, the average user will not see much difference in real-world gaming scenarios.
