I'm upgrading from an older Radeon RX 580, mainly for 4K photo and video editing in Adobe Premiere Pro with several color-grading plugins. I'm considering the RTX 5060 Ti with 8GB or 16GB of VRAM, the RTX 5070 with 12GB, or Intel's Arc B580. Gaming performance isn't important to me, so I'm unsure how much VRAM and GPU power matter for editing. My budget can stretch to the RTX 5070, but I'd prefer to stay somewhere in the $500–$700 range if possible. My current RX 580 has 4GB, struggles with effects-heavy Premiere projects, and can take around 30 minutes to render a four-minute video.

For 4K editing, I’d lean toward the RTX 5060 Ti 16GB. The extra VRAM gives you more headroom for high-resolution timelines, effects, color grading, and larger projects than the 8GB version. The RTX 5070 is worth considering if you use demanding effects or want more overall performance, but it may not improve basic encoding and decoding as much as its price suggests.
Before buying, monitor how much VRAM your RX 580 uses during the projects that currently perform poorly. Since yours only has 4GB and is already struggling, moving to at least 12GB or 16GB should provide a noticeable improvement. The best choice depends on whether your plugins are GPU-accelerated and which brands they support, so verify that before prioritizing raw specifications.
My RX 580 has 4GB, and it struggles particularly with effects-heavy projects. A four-minute project can take roughly 30 minutes to render, so I’m mainly looking for better performance with Premiere effects and color grading.
The Arc B580 could offer excellent value if Premiere Pro and your plugins support it properly. Intel’s hardware encoding and decoding are competitive with Nvidia’s for many workflows, but Nvidia still tends to have broader software support. Check compatibility with your exact Premiere version and plugins before choosing it. If you go Nvidia, the newer cards share much of the same encoding and decoding hardware, so the larger models aren’t automatically much faster for exports. Extra GPU power matters more when your projects exceed the available VRAM.
It’s also worth checking whether Premiere can use proxies. Proxies can make timeline playback much smoother, especially when working with 4K footage and multiple effects, though they won’t eliminate the need for enough VRAM during final renders.
