Editor's PickBest for Local LLMNew

NVIDIA

NVIDIA GeForce RTX 5090

32GB of GDDR7 at 1,792 GB/s makes the 5090 the highest VRAM consumer GPU shipping, fitting a full 30B model in fp8 or a quantized 70B with room for context.

·21,760 CUDA cores, 170 SMs, Blackwell architecture
·32GB GDDR7, 512-bit bus, 1,792 GB/s bandwidth
·5th gen Tensor cores, 4th gen RT cores, DLSS 4
·575W TDP, recommended 1000W PSU
·PCIe 5.0 x16, three DisplayPort 2.1, one HDMI 2.1b

AI use: Local LLMs up to 70B 4-bit quantized, 30B fp8, Stable Diffusion 3.5 and Flux at full resolution, single-GPU fine-tuning of 13B models

$2,899 to $3,999 (street, May 2026)

NVIDIA GeForce RTX 5080

16GB of GDDR7 at 960 GB/s puts the 5080 right at the 13B-fp16 and 30B-4bit sweet spot for builders who want CUDA without the 5090 tax.

·10,752 CUDA cores, Blackwell architecture
·16GB GDDR7, 256-bit bus, 960 GB/s bandwidth
·5th gen Tensor cores, 4th gen RT cores
·360W TDP, recommended 850W PSU
·PCIe 5.0 x16, three DisplayPort 2.1, one HDMI 2.1b

AI use: Local LLMs 13B fp16 or 30B 4-bit quantized, Stable Diffusion XL and 3.5, LoRA fine-tuning on 7B models, Claude Code at desktop speeds

$1,099 to $1,799

NVIDIA RTX 6000 Ada Generation

48GB of ECC GDDR6 in a 300W blower card is the right answer for builders who need a quiet workstation that can hold a 70B 4-bit model entirely on one GPU.

·18,176 CUDA cores, 142 RT cores, 568 Tensor cores
·48GB GDDR6 with ECC, 960 GB/s bandwidth
·300W TDP, dual-slot blower active cooling
·PCIe 4.0 x16, four DisplayPort 1.4a, AV1 encode and decode
·Workstation drivers, multi-GPU friendly

AI use: Local LLMs up to 70B 4-bit on a single card, 13B fp16, multi-GPU fine-tuning at 96GB and beyond, professional rendering and simulation alongside AI

$6,800 to $8,210
