The export speed is 2 times faster on the 2023 Lenovo Legion 5 Pro compared to the 2022 Asus ROG STRIX SCAR.
The export speed is 2 times faster on the 2023 Lenovo Legion 5 Pro compared to the 2022 Asus ROG STRIX SCAR.
I own an ASUS ROG STRIX SCAR 17 with an i9 12950HX and RTX 3080Ti from 2022, which I use for video editing. I’m testing a Lenovo Legion Pro 5 with an i9 13900HX and RTX 4060. The RTX 4060 is expected to be less powerful than the 3080 Ti GPU, and the 13th generation i9 is only marginally better than the 12th generation version. Compared to this, the older ASUS model has 64GB RAM and 16GB VRAM, while the Legion 5 Pro offers just 32GB RAM and 8GB VRAM.
I was hoping the 2022 ASUS would outperform the 2023 Legion 5 Pro significantly. However, I was surprised to see the newer Legion Pro 5 handled a test video at about 120 FPS, whereas the older ASUS only managed around 60 FPS and took nearly twice as long (73 seconds vs 37 seconds) to export the same file with the same software.
I ran both systems in their highest performance settings, using the same video and software, and exported without any editing. Both have PCIe 4.0 NVMe M.2 SSDs.
Could anyone please clarify why?
It seems the software might be leveraging a new feature from Nvidia.
Yes, this appears to be accurate, though reducing the processing time by half came as a surprise.
I also tried using Topaz Video AI 4.09 to enlarge an FHD 133-second video (2 minutes 13 seconds) to 4K resolution. The results are listed below:
2022 ASUS Intel i9 12950HX 64GB RAM DDR5-4800 NVIDIA RTX 3080 Ti 16GB VRAM:
878 seconds (14 minutes and 38 seconds)
CPU usage ranged from 70 to 80%
GPU VRAM usage was between 50 to 60 to 70 to 80%
Memory usage stayed around 20% (12 to 13 GB)
2023 Lenovo Intel i9 13900HX 32GB RAM DDR5-5600 NVIDIA RTX 4060 8GB VRAM:
662 seconds (11 minutes and 2 seconds)
CPU utilization reached 100%
GPU VRAM usage hit 100%
Memory utilization was about 36% (11.5 GB)
These numbers are more aligned, but the Lenovo model still managed to cut processing time by roughly a quarter. It seems my choice of hardware at the start was well worth it, especially near its CPU and GPU limits.
