Quick picks (August 2026)

Cheapest laptop per NPU tier (Aug 2026)

NPU tier (chip) NPU TOPS Cheapest realistic pick Street price (Aug 2026)
Snapdragon X2 Elite / Plus (“Glymur”) 80–85 Microsoft Surface Laptop 13.8″ (8th Ed); deals to ~$1,080 ~$1,080–1,400
Ryzen AI 400 (Medusa Point) 60 ASUS Zenbook 14 (Ryzen AI 9 465; open-box from ~$714) ~$750–1,200
Strix Point (Ryzen AI 300, HX 370) 50 mid-tier HX 370 ultrabooks ~$900–1,200
Intel Panther Lake (Core Ultra 300) ~50 HP OmniBook X Flip (Walmart listing) ~$999
Intel Lunar Lake (Core Ultra 200V) 48 2024–25 budget stock (deep discounts) ~$600
Snapdragon X Elite / X Plus 45 budget X Plus stock (Qualcomm “from $599”); X Elite from ~$1,000 ~$600–1,000
Apple M5 / M4 (Neural Engine) ~38 MacBook Air M5 (16-core NE) ~$1,099 (M4 Air from $999)

Prices are cheapest street configs (typically 16–32 GB RAM; the RAMpocalypse taxes higher capacities). All tiers run the same newest small-model stack (Ministral 3, Qwen3.5, Gemma 4) — the NPU number mostly decides battery life for always-on AI, not which models fit.

Laptop vs desktop at each budget (Aug 2026)

Budget Desktop pick (from build-guides.md) Laptop pick (from laptop-ai-guide.md) The honest trade-off Form factor (battery / noise / power / repairability)
~$700–1,000 Budget tower — used RTX 3060 12 GB (~$665–735): Ministral 3 14B Q4 @ 40–55 tok/s Zenbook 14, Ryzen AI 9 465 (~$900–1,150): 8B @ 25–40 tok/s + 60 TOPS NPU Desktop runs one tier bigger and ~35% faster per dollar; laptop is portable and battery-efficient Desktop: none / fans audible under load / ~12 W idle, ~275 W load / 9/10 — full ATX: socketed CPU, DIMM slots, PCIe GPU, standard PSU. Laptop: 8–12 h light, ~3 h sustained LLM / quiet / 65 W charger / 4/10 est. — RAM soldered; SSD & battery swappable
~$1,500 Mid tower — used RTX 5060 Ti 16 GB (~$1,465): Devstral 2 Q4, 27B/30B at Q3 Vivobook S16 X2 Elite 48 GB (~$1,599): 14B @ 20–30 tok/s, 8B on NPU Desktop unlocks the 24–30B tier (Q3/Q4); laptop caps at 14B but gives all-day on-device AI Desktop: none / moderate fan noise / ~400 W / 9/10 — full ATX. Laptop: 15–20 h light, all-day on NPU / near-silent / 65 W charger / 4/10 est. — 48 GB RAM soldered fixed; SSD & battery swappable
~$3,000 Desktop-only tier — used RTX 4090 24 GB (~$3,000–3,200): Gemma 3 27B + GLM-4.7-Flash at full Q4 — (no laptop equivalent) The full-Q4 27–30B experience has no laptop answer in 2026 Desktop: none / 4090 loud at 450 W (35 dBA) / ~7–33 W idle, ~650 W load / 9/10 — ATX; used card: plan repaste + check the 12VHPWR connector
~$5,200–6,300 High tower — RTX 5090 32 GB (~$5,300–6,300): 27–30B @ 60–90 tok/s, Mistral Medium 3 ⚠ M5 Max 128 GB (~$5,200–5,900): 27–30B @ 40–55 tok/s, plus Mistral Medium 3, gpt-oss-120B, 72B vision The 2026 inversion: the laptop holds bigger models (128 GB unified > 32 GB VRAM); the desktop is faster on what fits (1.79 TB/s vs ~700 GB/s) Desktop: none / 5090 loud at 575 W (40 dBA) / ~30–46 W idle, ~800 W load / 9/10 — ATX, GPU swappable. Laptop: 15–20 h light, ~3–5 h sustained LLM / silent at idle, fans on under max load / 140 W charger, ~100 W sustained (147 W peak) / 4/10 (iFixit) — RAM & SSD soldered, Apple repairs pricey
~$4,700 (turnkey) DGX Spark — 128 GB unified, capacity to 120B, slow decode The Spark is the “desktop that holds laptop-class memory” — same 128 GB capacity class as the M5 Max No battery / quiet SFF (minor coil whine) / ~25–45 W idle, ~150 W load / 4/10 est. — 128 GB RAM soldered on-package; 2242 SSD user-swappable

Form factor cell format: battery life · noise · power draw · repairability (iFixit-style 0–10, 10 = easiest; “est.” = scored from teardown reports, no official iFixit score). Power draw = system under sustained LLM load (GPU TDP + platform); noise notes assume a mid-tower case with decent fans.

Repairability scores & teardown sources:

Measured power & noise (from 2025–26 reviews)

Measured at the wall where noted; “GPU” figures are card-only, “system” figures include the rest of the PC. “est.” = no direct measurement found, estimated from comparable hardware/reports.

Cost per token & per watt (Aug 2026)

Method: hardware price + electricity amortized over 2 h/day of sustained single-stream inference at each pick’s flagship speed (midpoint from compatibility-matrix.md). Desktops amortized over 5 yr, laptops 4 yr (battery/soldered-RAM life); $0.17/kWh US average. Draw = sustained LLM-load figure from the form-factor column.

Pick Price Flagship run (tok/s) System draw $/M tokens $/W Tokens/kWh
Budget tower · RTX 3060 12 GB ~$700 Ministral 3 14B Q4 · 47 ~275 W ~$1.4 $2.5 ~0.62M
Zenbook 14 · Ryzen AI 9 465 ~$1,025 Ministral 3 8B · 32 ~45 W ~$3.1 $23 ~2.6M
Mid tower · RTX 5060 Ti 16 GB ~$1,465 Devstral 2 Q4 · 52 ~400 W ~$2.5 $3.7 ~0.47M
Vivobook S16 · X2 Elite 48 GB ~$1,599 14B · 25 (8B on NPU · 30) ~50 W ~$5.1–6.2 $32 ~3.6M (NPU)
24 GB tower · used RTX 4090 ~$3,100 Gemma 3 27B Q4 · 47 ~650 W ~$5.7 $4.8 ~0.26M
High tower · RTX 5090 ~$5,800 Gemma 3 27B Q4 · 75 ~800 W ~$6.5 $7.3 ~0.34M
M5 Max 128 GB ~$5,550 Gemma 3 27B Q4 · 47 ~100 W ~$11.3 $56 ~1.7M
DGX Spark $4,699 Gemma 3 27B · 15 ~150 W ~$24 $31 ~0.36M

What the numbers say:

Bottom line: under $5K the desktop wins for LLMs per dollar (VRAM > everything — see the fitting math below). At $5K+ the rules invert: the M5 Max laptop and DGX Spark (128 GB unified) beat a 5090 tower on model capacity, while the tower wins on speed and image gen. The 24 GB Q4 sweet spot (~$3,000) is desktop-only.

Cloud/API alternatives: same workload, cost per token (Aug 2026)

Same usage envelope as the local table: 338K output tokens/day (2 h/day at the budget tower’s 47 tok/s), 3:1 input:output ratio, cache-miss pricing. Sources: DeepSeek pricing · OpenAI pricing · Anthropic Opus 4.6 announcement. Checked Aug 9, 2026.

API model Input $/M Output $/M Cost/day Cost/5 yr vs budget tower (~$871/5 yr)
DeepSeek V4 Flash 0731 (value king) $0.14 $0.28 ~$0.24 ~$430 API is cheaper than every local build
GPT-5.3-Codex (closed) $1.75 $14.00 ~$6.51 ~$11,900 local is 13.6× cheaper
Claude Opus 4.6 (closed) $5.00 $25.00 ~$13.54 ~$24,700 local is 28× cheaper

Break-even (heavy daily use): GPT-5.3-Codex pays for the budget tower in ~4.5 months and the 5090 tower in ~2.6 years; Claude Opus 4.6 pays for the budget tower in ~2 months and the 5090 tower in ~15 months. DeepSeek V4 Flash never breaks even — at this usage the API is simply cheaper for five straight years.

What this means:

Decision tree: which one should you buy?

Five plain-English questions — each answer points to the next. Full detail in the build guides and laptop guide.

Shortcuts for common cases:


Model-fitting math (read this before the category files)

Two rules of thumb dominate “can I run model X?” and “how fast?”:

1. Does it fit in memory?

A Q4_K_M (4-bit) quantized model needs roughly 0.55–0.6 GB per billion parameters, plus ~1–2 GB for context/KV cache and the runtime.

Model (current examples) Params Q4_K_M size Needs at least
Ministral 3 3B / Qwen3.5 & Gemma 4 sub-12B 3–12B 0.7–7 GB 4–16 GB
Ministral 3 14B / Gemma 3 12B 14B ~8.6 GB 12–16 GB
Devstral 2 / Gemma 3 27B 24–27B 14–16.5 GB 16–24 GB
GLM-4.7-Flash (30B-A3B MoE) 30B ~19 GB 24–32 GB
Mistral Medium 3 / gpt-oss-120B 48–120B 28–70 GB 48–128 GB
MiniMax M2.5 230B ~130 GB 128–256 GB
Mistral Large 3 / GLM-5.2 675–744B 380–420 GB 512–748 GB+

2. How fast will it decode?

LLM generation is memory-bandwidth-bound: decode tokens/sec ≈ memory bandwidth ÷ model size (× ~0.7–0.8 efficiency). This is why a 32 GB RTX 5090 (1.79 TB/s) is so much faster than a 128 GB DGX Spark (273 GB/s) on the same small model — and why big-memory machines are great for fitting huge models but generate slowly.

Example ceilings: 8B Q4 on RTX 5090 → ~150+ tok/s; on DGX Spark → ~35–40 tok/s. Gemma 3 27B Q4 on DGX Spark → ~15 tok/s; MiniMax M2.5 Q4 on an M5 Ultra Studio → ~8–10 tok/s (slow but possible).
