Overall, the RTX 5090 is a beast of a card. Drawing 575 W, with 32 GB VRAM and a $2000 price tag (at least), it is overkill for many use cases. However, it excels at GPU-heavy workloads like rendering and provides solid performance improvements over the last-gen 4090 in many applications. There are some issues with software compatibility that need to be worked out, but historically, NVIDIA has been great about ensuring its products are properly supported throughout the software ecosystem.
For video editing and motion graphics, the RTX 5090 performs well, with 10-20% improvements across the board. In particular sub-tests, where the workload is primarily GPU bound, we see up to 35% performance advantages over the previous-generation 4090. However, the area we are most excited about is actually the enhanced codec support for the NVENC/NVDEC engines. In DaVinci Resolve, the H.265 4:2:2 10-bit processing was more than twice as fast as software decoding and exceeded even what we see from Intel Quick Sync. Even if the 5090 is more than a workload requires, we are excited to see what this means for upcoming 50-series cards.
https://www.pugetsystems.com/labs/artic ... on-review/Overall, the RTX 5080 is a solid GPU that provides good performance nearly across the board. However, following our 5090 review, we are somewhat disappointed by the relatively small performance uplifts over the RTX 4080 SUPER. In some places, the 5090 seemed to justify the price increase over the 4090 with staggering performance increases. For the 5080, the same price seems to get you basically just the same performance in many workloads.
In video editing and motion graphics, the RTX 5080 is about 5-10% faster than the RTX 4080 SUPER and 20-30% faster than the 3080 Ti. There were some standout areas, such as 3D performance in After Effects, with gains double those. DaVinci Resolve is largely the same, with the stand-out areas being the improved LongGOP processing and GPU Effects, but otherwise modest performance improvements. Still, for new-to-PC users or those on even older cards, it offers a solid upgrade.
So if render times make you money, the 5090 is probably worth it.
Big news is h.265 4:2:2 support added, So intel isn't the only game in town.

5070 numbers if you care
