Can I Run Phi-4 Family on Intel Arc B570?
Written by Jakub Rusinowski · Last updated July 12, 2026
Only with offload — Phi-4 (14B) at Q4_K_M needs 10.9 GB at 8K context (8.5 GB weights + 2.4 GB KV cache/overhead) against the Intel Arc B570's 10 GB, so part of it spills onto CPU/system RAM and speed drops sharply.

Phi-4 (14B) on the Intel Arc B570: VRAM by quantization
| Quant | VRAM needed | Fits 10 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 30.5 GB | ✗ No | — | — |
| Q8_0 | 17.4 GB | ✗ No | — | Build for this |
| Q6_K | 14 GB | ✗ No | — | — |
| Q5_K_M | 12.4 GB | ✗ No | — | Build for this |
| Q4_K_M | 10.9 GB | ✗ No | — | Build for this |
| Q3_K_M | 8.4 GB | ✓ Yes | 8K | — |
| Q2_K | 7.1 GB | ✓ Yes | 16K | — |
Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 10 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the Intel Arc B570: 8K 10.9 GB ✗ · 16K 12.6 GB ✗. Past 8K it no longer fits 10 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Phi-4 (14B) on 16 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Phi-4 Family variant requires more VRAM than the Intel Arc B570 provides (10 GB).
Nearest GPU That Fits
NVIDIA GeForce RTX 2080 Ti (11 GB VRAM).
Phi-4 Family needs ~11 GB but this GPU has 10 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:

FAQ
Is the Intel Arc B570 enough to run Phi-4 Family locally?
Only with offload — Phi-4 (14B) at Q4_K_M needs 10.9 GB at 8K context (8.5 GB weights + 2.4 GB KV cache/overhead) against the Intel Arc B570's 10 GB, so part of it spills onto CPU/system RAM and speed drops sharply.
What's the cheapest GPU that runs Phi-4 Family?
The NVIDIA GeForce RTX 2080 Ti (11 GB VRAM) is the cheapest upgrade that fits it.
