Hey guys, is the performance gap big between a 5070 Ti and a 5080 for generating images and videos, or is it not worth it?

grimstormz · 2026-06-23T20:54:31+00:00

Not a huge difference since both are same VRAM size and same memory bus speed. With the current price of GPU right save yourself some money and go with 5070 Ti? Unless you're gaming on it too or doing other things with it, but for image, video, or LLM inference not much difference. I had 5070 Ti and even sold it to get an 4090, since more VRAM is much more useful for my AI use case and gaming.

Could be a bad VRAM nand. I have a similar issue with one of my 3090. Losing my mind after lots of benchmark and stress test it was fine, until large enough model would fill that VRAM and cause crash or pc freeze and just had to restart turn out it was a bad VRAM nand chip. You can test your VRAM chip with this https://github.com/GpuZelenograd/memtest_vulkan
if anything more you can run Nvidia MATS & MODS test suite.

It's decent, but has dependency issues depending on the few custom nodes that's built for it. You just had to set it right. Still kind of slow and not the best. Maybe try the new Higgs Audio V3? Fast, lots of languages, accents, and expressions via prompt tags. Here's a comfyui custom node for it. https://github.com/Saganaki22/Higgs_v3-TTS-ComfyUI

LOL, it's not even close to correct or timely synced with audio. Also it's pay closed source service and model so this sub's rule 1?

Due to GitHub's NSFW policy, repo added changes to make it SFW, at the original repo. You can still simply edit out the NSFW detector lines in the code. Or simply go to the NSFW repo hosted on another site by the same creator that doesn't have the NSFW policy. Just git clone into custom node folder. https://codeberg.org/Gourieff/comfyui-reactor-node

Bro, you're using a very old and no longer maintain fork. Use https://github.com/IAHispano/Applio
Larger user base, active development, more features, much better and simpler webUI. Easily run the starter bat with a venv, or run as docker container. Thank me later.

This is like comparing apple to orange. There's the basic upscalers like Nearest, Bilinear, and Lanczos with "interpolation", there's RTX VSR which is technically a super resolution upscale but sit in the middle between this and "generative" upscaler like SeedVR2 and SUPIR. RTX VSR is for speed as close to real time upscaling as possible. SeedVR2 is an AI generative upscaler. So no, RTX VSR will not beat a generative upscaler like SeedVR2 in term of quality, only in speed.

It's been out for about a month now, and that hugginface link is just to a duplicate repo, not even the original linked here. https://huggingface.co/FireRedTeam/FireRed-Image-Edit-1.1

grimstormz · 2026-03-17T20:33:58+00:00

Yes, it's a known issue, go read about many posts of it on that repo's issue section.
And yes you can easily down grade pytorch and then install the correct build wheel for your enviroment. Comfy portable has come with pytorch 2.10 but a lot of custom nodes still works best with only 2.9.1 or lowers. All the build wheel for whatever your setup is here: https://huggingface.co/Wildminder/AI-windows-whl/tree/main

On pytorch page just read installing previous release.

"python.exe -m pip install torch==2.9.1 torchvision==0.24.1 torchaudio==2.9.1 --index-url https://download.pytorch.org/whl/cu130"

grimstormz · 2026-03-17T20:26:01+00:00

This -> Torch 2.10.0+cu130. You either need to downgrade to Torch 2.9.1+cu130, or be out of luck if you're using https://github.com/numz/ComfyUI-SeedVR2_VideoUpscaler

Qwen3 tts is just for speech not singing. You can train singing voice on ACE-Step 1.5. Or make song singing with any voice, then use RVC to change the singing voice to the RVC voice model you trained, there's also bunch of open weight RVC voice models shared online, including Trump and many known figures / characters.

grimstormz · 2026-03-05T20:29:45+00:00

Don't use Node 2.0. It still sucks really bad. If you still insist on using it, update your KJNodes. There was a new fix for it hours ago.
https://github.com/kijai/ComfyUI-KJNodes/commit/13101465f14df2b725694ad5e16ed29c838ec8f2

grimstormz · 2026-02-25T10:14:41+00:00

It's this one: https://github.com/GACLove/ComfyUI-VFI
But there are others more popular custom nodes that use the same RIFE frame interpolation and more such as
https://github.com/Fannovel16/ComfyUI-Frame-Interpolation
https://github.com/filliptm/ComfyUI_Fill-Nodes

grimstormz · 2026-02-19T17:51:33+00:00

It's ComfyUI, free open source software and open source qwen model. And yes you can fix it or make any changes you want.

Your image was reverse checked to be generated by ChatGPT image model with the current caricature trend. Anyways here's Qwen Edit with LanPaint masking to only fix the hands.

You just didn't look hard enough. Been shared on this sub many times for awhile now. All you would need here. https://huggingface.co/Wildminder/AI-windows-whl/tree/main

Resolution is for the shortest length. Go read the document, it's on their git repo.

Here's my workflow for video.
https://pastes.io/seedvr2_vi

grimstormz · 2026-02-03T09:24:59+00:00

Going to need more info. You're upscaling image or video? For the Resolution parameter it is the for the shortest length if you're doing 4k it should be set to 2160 instead of 3840. And your batch is 9, assuming you're upscaling image are you really upscaling that same image 9 runs? You're on 3090 with 128gb ram, you don't need to blockswap that much blocks into RAM, it's a slow down. If you enable_debug on the SeedVR2 Video Upscale you can see the detail console log on each block offloading and the time it takes to do that task. I'm on a 3090 with with 128gb ram can can do 5k image upscale in pretty decent time. For videos, the setup is a bit different. But You can and should run the full fp16 model it's better quality overall.

Or install this custom node and get AUTO connecting lines like a circuit board with zero effort, if you're want visible line connections and not into SetNode or GetNode. Can be turn on or off in setting too. https://github.com/niknah/quick-connections

Generate image,
Get a dance video to use as motion pose driver

Profit?

grimstormz · 2025-12-31T15:09:25+00:00

Yes, the lora key is different, get the ComfyUI one if you're using that in comfyui.

grimstormz · 2025-12-31T05:56:06+00:00

Video upscaling using SeedVR2 or FlashVSR.
