What is the best GPU for 4K video editing in 2024?

Question

So I've been stuck on this decision for like three weeks now and my current laptop is literally screaming every time I open Premiere Pro. I'm finally pulling the trigger on a dedicated editing rig because I've got a couple of wedding gigs lined up for the summer and I can't be dealing with proxy files for every single 4K clip anymore. It's just such a time sink. I'm located near a Micro Center so I can grab parts pretty quick but the GPU is where I'm totally hitting a wall.

I have about $800 to $1000 set aside just for the card. I did a bunch of digging on Puget Systems and some YouTube benchmarks and everyone seems to point toward the RTX 4080 Super being the sweet spot for 2024. But then I see these deep-dive threads where people swear that if you're using DaVinci Resolve specifically, you need as much VRAM as humanly possible, which makes me look at a used 3090 or even stretching for a 4090 though that's way over budget. Then there's the whole Intel Arc thing which some people say is amazing for QuickSync and AV1 but I'm worried about driver stability when I'm on a deadline.

The thing is I mostly work with 10-bit 4:2:2 footage from my Sony A7IV and drone shots that are super compressed. I've read that NVIDIA is better for the encoding side but then someone else says AMD's 7900 XTX has more raw power for the price and 24GB of VRAM which sounds great for 4K timelines. I just don't want to drop a grand on a card and still see stuttering when I'm color grading or adding a few layers of effects. Here is what I'm looking at:

RTX 4080 Super (new)

RTX 3090 (used market)

RX 7900 XTX

Is the 16GB on the 4080 Super actually enough for heavy 4K projects in 2024 or am I gonna regret not getting something with more memory? What are you guys actually using in your builds right now that doesn't break the bank but handles 4K like a champ?

> Is the 16GB on the 4080 Super actually enough for heavy 4K projects in 2024 Honestly, I had pretty high hopes for the AMD Radeon RX 7900 XTX 24GB GDDR6 given that massive VRAM pool, but it was really disappointing in Premiere. I kept getting these random driver timeouts during long exports which is the absolute last thing you want when you have a client deadline. Unfortunately, AMD just doesnt have the same level of optimization as NVIDIA for the Adobe suite yet, and the extra memory didnt make up for the stability issues. If you check the Puget Systems hardware database or even the EposVox deep dives on encoding, youll see raw power isnt everything. The NVIDIA GeForce RTX 4080 Super 16GB is the safer bet for stability, even if 16GB feels kinda stingy for a grand. My biggest issue with picking up a used NVIDIA GeForce RTX 3090 24GB is the insane power draw and heat. I had one that basically cooked my other components until I swapped it out for something more efficient. The real disappointment tho is that neither the 4080 nor the 7900 XTX can actually hardware decode that 10-bit 4:2:2 footage from your Sony A7IV. Its a weird technical gap where only Intel QuickSync on a chip like the Intel Core i9-14900K 24-Core Processor or Apple Silicon handles it natively. So, youre still gonna see some stuttering regardless of which $1000 card you buy if your CPU isnt doing the heavy lifting for those specific codecs. It isnt as good as we expected for the price, but the 4080 Super is the least likely to give you a headache.

@Reply #1 - good point! If youre sitting on a $1000 budget, the NVIDIA GeForce RTX 4080 Super 16GB is probably the most sensible path. A lot of people get hung up on wanting 24GB of VRAM like on the NVIDIA GeForce RTX 3090 24GB, but for 10-bit 4K stuff from an A7IV, 16GB is plenty. Unless youre planning to do massive 3D environments or crazy noise reduction in Resolve, you wont even touch that ceiling. The 4080 Super is significantly more power efficient than the older cards too. My old 30-series rig used to heat up the whole office during summer exports... not ideal when youre grinding through wedding footage for 8 hours. If you want to save some cash for extra storage or RAM, the NVIDIA GeForce RTX 4070 Ti Super 16GB is another solid mid-range option that still gives you that 16GB buffer. Stick with Nvidia for Premiere tho. The CUDA acceleration is just more mature and you wont be fighting the software as much. Buying new at Micro Center gives you that warranty peace of mind which is huge when youre doing professional gigs. Used 3090s are tempting but you never know if theyve been mined on or if the thermal pads are shot and failing on you.

The best GPU is the one with proper hardware decoders for 10-bit 4:2:2. Over the years, Ive seen folks prioritize raw VRAM instead and it just leads to a laggy timeline mess.
