So Ive been cutting 1080p footage for years on my old build with a GTX 1070 and it was always fine but I just landed this huge freelance gig shooting a wedding in 4K 10-bit and my timeline is absolutely crawling. Its weird because my CPU usage stays pretty low but the playback just stutters like crazy even at 1/4 resolution which is super frustrating when trying to show a client a rough cut.
I tried a few things to fix it:
- making proxies which took forever
- clearing the media cache
- toggling hardware acceleration
But honestly it still feels sluggish so I think its time for new gear. I was looking at the RTX 4070 Ti Super or maybe just a 4080 but I keep hearing mixed things about how much Premiere actually utilizes the VRAM versus the raw clock speed. My budget is around 800 bucks maybe a bit more if it really makes a huge difference for the render times and since I live in a smaller town I have to order everything online so I dont want to deal with returns. Is the extra VRAM on the 16GB cards actually worth the premium for 4K timelines or is it just marketing fluff? Im trying to get this sorted before my next shoot at the end of the month...

Quick reply while I have a sec. Basically everyone is agreeing that 16GB VRAM is the safest bet for 10-bit files. Id go that route just to be sure you dont have to upgrade again next year.
- use NVIDIA Studio Drivers specifically
- check if your PSU has enough headers The ASUS TUF Gaming GeForce RTX 4070 Ti Super 16GB is a very solid, reliable choice that fits your budget well.

Jumping in here because I had a similar headache with a documentary project last year. Honestly, my rig kept tripping the OCP on the PSU during heavy renders. Before you buy, what wattage is your current power supply? If you dont have enough headroom, the ZOTAC Gaming GeForce RTX 4080 Super Trinity 16GB GDDR6X offers better stability.
- 16GB VRAM prevents the frame buffer from overflowing into slow system RAM
- Better cooling prevents thermal throttling on long exports

Im happy using the NVIDIA GeForce RTX 4070 Ti Super 16GB GDDR6X for 10-bit work.
- 16GB VRAM fixes buffer errors
- Fast clocks reduce render times Works well no complaints.

Building on the earlier suggestion, that 16GB of VRAM really is the sweet spot for 10-bit. Ive been through a ton of hardware cycles and the Gigabyte GeForce RTX 4070 Ti Super Gaming OC 16GB is the best bang for your buck right now. Those dual encoders make a massive difference for 4K timelines... honestly, you wont believe the jump from your 1070, its gonna be night and day for those wedding edits.

Unfortunately, relying on anything less than 16GB was not as good as expected for 10-bit playback. I had issues with significant lag during my last project because the frame buffer simply couldnt handle the overhead. Methodically, you should just get any high-end card from NVIDIA to ensure the Mercury Playback Engine functions correctly. Their drivers are simply more reliable for professional video work.
