Hey everyone! I’m finally looking to upgrade my workstation because my current setup is absolutely choking on 4K footage. I primarily work in DaVinci Resolve and Premiere Pro, and lately, I’ve been dealing with a lot of heavy 10-bit 4:2:2 files from my Sony A7S III. My old RTX 2060 was fine for 1080p, but the stuttering timeline lag and massive render times for high-res projects are becoming a real productivity killer.
With all the new hardware releases we've seen so far in 2024, I'm feeling a bit overwhelmed by the options. I’ve heard that VRAM is absolutely critical for smooth 4K editing and color grading, so I’m debating whether to go for something like the RTX 4080 Super for those reliable CUDA cores or if an AMD RX 7900 XTX is a better move due to its massive 24GB of VRAM. I also use several AI-based plugins for noise reduction and upscaling, which I know can be super demanding on the GPU. My budget is around $1,000, and I really want a card that handles AV1 encoding efficiently for future-proofing.
Between the latest NVIDIA and AMD offerings, which specific card currently provides the smoothest real-time playback for 4K timelines without needing to generate proxies every single time?

> I’m debating whether to go for something like the RTX 4080 Super... or if an AMD RX 7900 XTX is a better move due to its massive 24GB of VRAM. Before I give advice, quick question - what CPU are u running? Honestly, those 10-bit 4:2:2 files are a nightmare because most GPUs dont have native hardware decoding for that sub-sampling. It's usually the CPU's integrated graphics (like Intel QuickSync) that handles the heavy lifting, not the card! But yeah, comparing the two: NVIDIA GeForce RTX 4080 Super 16GB vs AMD Radeon RX 7900 XTX 24GB The NVIDIA card is the reliable, "safe" pick. CUDA is basically the industry standard and its super stable for AI plugins. Tbh, the AMD card is great for the raw VRAM, but I've found it a bit finicky with driver stability. I'm realy satisfied with NVIDIA's reliability, but definitely check your CPU first so you dont waste $1k. Cheers!

I would suggest being careful with those 10-bit 4:2:2 files. tbh I went thru this last year and my old setup just couldnt hack it... literally unplayable. I ended up getting a high-end NVIDIA card because the CUDA cores are way more reliable for those AI plugins. Plus, their hardware encoders usually play nicer with Sonys codecs in Resolve. Make sure to not skimp on VRAM tho!
