RTX 4070
A consumer-grade graphics card released by NVIDIA, based on the Ada Lovelace architecture, suitable for local deep learning and fine-tuning of small-scale models.
Timeline (last 90 days)
When a developer fine-tuned a 7B model on a home RTX 4070, a single full QLoRA training run took about 11 hours.
The developer reflected that if performance profiling had been done on the local RTX 4070 from the start, the dataloader would have been found to be a bottleneck just as well, because in the local environment the slower GPU masked the data loading shortcoming.
After the developer rented an H100, the first end-to-end training run took 9.5 hours, only about 15% faster than the RTX 4070.
A Reddit user completed a video generation test of character face swapping using an RTX 4070 with 8 GB of VRAM, paired with the MiniMax H3 model and the Character Swap LoRA.
Compared to the previous-generation RTX 4070 series, the RTX 5070 shows improvements in shader core count, VRAM bandwidth, and AI compute performance
The INT8-quantized CONVROT version of the YuE2 model requires approximately 8 GB of VRAM and can run on consumer-grade GPUs such as the RTX 4070 12 GB.
桌面版RTX 4070的TDP为200W，而笔记本版通常被限制在80-115W之间
RTX 4070拥有5888个CUDA核心
