What AI models can the AMD Radeon RX 7800 XT 16 GB run?

At 4-bit quantization with an 8K-token conversation, 28 of the 146 open-weight models in our directory fit entirely in the AMD Radeon RX 7800 XT 16 GB's 16 GB of video memory (about 15 GB usable), up to Safety GPT OSS 20B. With 32 GB of dual-channel DDR5-5600, 33 more run partly from system RAM, more slowly. Among models of 7B parameters or more, GPT OSS 20B is the fastest, at an estimated 97 to 125 tokens per second.

Compared with similar cards

  • NVIDIA GeForce RTX 5070 12 GB: 12 GB, 25 models fit entirely (-3); about 19% faster on models that fit both (672 vs 624 GB/s, and AMD cards run llama.cpp less efficiently than NVIDIA's).
  • NVIDIA GeForce RTX 5080 16 GB: same memory, so the same models fit; about 63% faster on models that fit both (960 vs 624 GB/s, and AMD cards run llama.cpp less efficiently than NVIDIA's).
  • NVIDIA GeForce RTX 5070 Ti 16 GB: same memory, so the same models fit; about 54% faster on models that fit both (896 vs 624 GB/s, and AMD cards run llama.cpp less efficiently than NVIDIA's).
  • NVIDIA GeForce RTX 4080 SUPER 16 GB: same memory, so the same models fit; about 29% faster on models that fit both (736 vs 624 GB/s, and AMD cards run llama.cpp less efficiently than NVIDIA's).
  • NVIDIA GeForce RTX 4090 24 GB: 24 GB, 60 models fit entirely (+32); about 70% faster on models that fit both (1008 vs 624 GB/s, and AMD cards run llama.cpp less efficiently than NVIDIA's).

Frequently asked questions

What is the largest AI model the AMD Radeon RX 7800 XT 16 GB can run?

At 4-bit quantization with an 8K-token conversation, the largest model in our directory that fits entirely in its 16 GB of video memory is Safety GPT OSS 20B (14 GB). With 32 GB of dual-channel DDR5-5600 for the overflow, larger models such as Skyfall 36B V2 also run, more slowly, partly from system RAM.

Can the AMD Radeon RX 7800 XT 16 GB run GPT OSS 20B?

Yes. At 4-bit, GPT OSS 20B needs about 14 GB and fits entirely in the AMD Radeon RX 7800 XT 16 GB's memory at an estimated 97 to 125 tokens per second.

Can the AMD Radeon RX 7800 XT 16 GB run Qwen3 32B?

Partly. Qwen3 32B needs about 23 GB at 4-bit, so about 7.4 GB runs from system RAM (assuming 32 GB of dual-channel DDR5-5600) at an estimated 3.3 to 4.5 tokens per second.

Can the AMD Radeon RX 7800 XT 16 GB run OpenAI GPT 120B?

No. OpenAI GPT 120B needs about 72 GB at 4-bit, more than the AMD Radeon RX 7800 XT 16 GB can hold even with 32 GB of dual-channel DDR5-5600 for overflow.

These are estimates, not measurements: memory from each model's parameter count and published architecture, speed from memory bandwidth, calibrated on the AIPCs test bench. Drivers, software and prompt length move real results. How the estimate works.
