AI GPU Buying Guide
The GPU is the single most important component for AI workloads, and the market moves fast. New architectures, shifting prices, and evolving model requirements mean last year's advice is already outdated. This hub brings together our GPU comparisons, VRAM deep-dives, and benchmark roundups so you can make a confident buying decision — whether you're running inference on a budget, training models, or building a multi-GPU rig for production workloads.

Cohere North Mini Code 1.0 — Local Hardware Guide (2026): What GPU or Mac You Actually Need
Cohere's North Mini Code 1.0 is a 30B-total / 3B-active MoE, so its w4a16 quant needs only ~18–20GB of memory — it runs on a single used RTX 3090, an RTX 4090, or a 32GB Apple Silicon Mac, while its 3B active parameters keep decode fast even on that modest hardware. Here's the exact card-by-card buying answer, with prices and a VRAM-to-tok/s table.
ReadGuideHow to Run Kimi K2.6 Locally (2026): The Real Hardware It Takes — and the Cheapest Rig That Actually Works
Kimi K2.6 (Moonshot AI, April 2026) is the leading open-weight coding model — a 1.04T-parameter MoE with 32B active. Here's the honest answer: you basically can't run it on one card. Full per-quant memory table (Q2→FP16), the cheapest rig that fits (4× RTX 3090 + 256GB RAM ≈ 350GB), the 8×H200 money-no-object path, and a clean offramp to smaller models if your box can't reach 350GB.
ReadGuideBest GPU for a Local Coding Assistant in 2026: VRAM Tiers to Replace Copilot with Qwen3-Coder, GLM-5.2 & Kimi K2.7 Code
Local coding models finally got good enough to cancel a Copilot subscription — but only if you buy the right card. This is a buyer's guide organized by VRAM tier, not by model: spend $X, run coding-model tier Y. The short answer: a $429 RTX 5060 Ti runs Qwen3-Coder for tab-complete plus a 30B-A3B model for agentic chat, and pays for itself versus a $20/month subscription in under two years.
ReadGuideGLM-5.2 Local Hardware Guide (2026) — What It Actually Takes to Run the Best Open Coding Model at Home
Z.ai's GLM-5.2 is a 743B-parameter MoE (≈39B active) that tops the open-source coding leaderboards — and it's free to download. Here's the honest hardware answer: the 2-bit GGUF needs ~239GB of memory, which means a 256GB-class Mac Studio, a 4× RTX 3090 rig with 192GB RAM, or an 8×H200 server for FP8 — plus the off-ramp for everyone who can't hit 240GB.

ROCm 7.2 finally fixed the AMD-for-AI software story. Here are the four AMD GPU buyer paths that matter in June 2026 — RX 7900 XTX at $899 for 24 GB, RX 9070 XT at $600 for the mid-range, Strix Halo unified memory at sub-$2,500, and MI300X / MI250X for self-hosted production — plus the explicit don't-buy cards.

DeepSeek V4-Flash dropped April 24 under MIT license: 284B total / 13B active, 1M context, Claude Haiku-tier API pricing. Here's what hardware actually runs it locally — five priced buyer paths from $5,999 Mac Studio to $11K RTX PRO 6000, the 90 GB don't-bother cutoff, and why the MoE active-parameter math reframes every decision.
ReadGuideQwen 3.6-35B-A3B Local Hardware Guide 2026: The $800 GPU That Now Runs a Frontier MoE
Alibaba's Qwen 3.6-35B-A3B (released 2026-04-16, Apache 2.0) is the first frontier-class open coding model that runs usefully on a single used RTX 3090 — because only ~3B of its 35B parameters are active per token. Full quantization table, five priced buyer paths from $249 to $2,000, Mac Studio unified-memory coverage, and the MoE math that explains why an $800 GPU now keeps up.
