CPU only (system RAM)

The CPU only (system RAM) has 0 GB VRAM and 80 GB/s memory bandwidth. It can run 0 of our 97 tracked models natively in VRAM at 8k context.

With 0 GB DDR4 / DDR5, the CPU only (system RAM) is a integrated-tier GPU that can run 0 models natively. 7B at Q4 ~1-5 t/s depending on AVX2/AVX-512 support. 14B ~0.5-2 t/s.

CPU only (system RAM): x86-64/ARM with DDR4/DDR5 at ~80 GB/s, CPU inference fallback.

7B at Q4 ~1-5 t/s depending on AVX2/AVX-512 support. 14B ~0.5-2 t/s.

llama.cpp CPU backend. AVX2 or AVX-512 recommended. Expect 1-5 t/s for 7B on modern desktop CPU.

None.

Models that fit with CPU offload (53)

These use system RAM for layers that don't fit in VRAM, so expect much slower inference.

Frequently asked questions

How much VRAM does the CPU only (system RAM) have?
The CPU only (system RAM) has 0 GB of DDR4 / DDR5 with 80 GB/s memory bandwidth.
What is the CPU only (system RAM) best for?
With 0 GB of VRAM, the CPU only (system RAM) is best for running compact models (1B–8B) at low quantization, suitable for edge inference, prototyping, and lightweight tasks.
What LLMs can the CPU only (system RAM) run locally?
The CPU only (system RAM) cannot run any of the 97 tracked models fully in VRAM at 8k context. It may handle smaller models with CPU offload.
Can the CPU only (system RAM) run Gemma 4 31B?
The CPU only (system RAM) can run Gemma 4 31B with CPU offload at Q5_K_M quantization, but inference will be slower than native VRAM execution.
Can the CPU only (system RAM) run Qwen 3.6 27B?
The CPU only (system RAM) can run Qwen 3.6 27B with CPU offload at Q6_K quantization, but inference will be slower than native VRAM execution.
Can the CPU only (system RAM) run Qwen3 8B?
The CPU only (system RAM) can run Qwen3 8B with CPU offload at BF16 quantization, but inference will be slower than native VRAM execution.
