RTX A5500

The RTX A5500 is an NVIDIA GPU built on the Ampere architecture, released 2022-03-22. For running AI locally, the numbers that matter are its 24 GB of GDDR6 and 768 GB/s of memory bandwidth. VRAM decides which models fit at all; bandwidth sets how fast they generate text.

What you can run on 24 GB

At Q4_K_M quantization (the usual local default), 24 GB holds models up to roughly 38B parameters, leaving headroom for context. On this card you can run, among others:

Larger models need a higher-VRAM card, a second GPU, or CPU offload (which is much slower). Check any specific model with the VRAM calculator, or see the full picture on what can I run.

Local LLM speed (LLaMA 3, llama.cpp)

Single-stream token-generation throughput - estimated from memory bandwidth:

Model (quant)Speed on RTX A5500
Llama 3 8B (Q4_K_M)89.9 tok/s
Llama 3 8B (F16)40.8 tok/s
Llama 3 70B (Q4_K_M)✗ won't fit

Because decode is memory-bandwidth bound, the 768 GB/s figure is the best single predictor of chat speed on this card. Estimates are calibrated against measured RTX-40-series cards and are typically within ~15%.

Memory and power

  • VRAM: 24 GB GDDR6 (384-bit bus)
  • Bandwidth: 768 GB/s
  • TDP: 230 W - a 550 W+ power supply is recommended
  • Process: 8 nm
  • Interface: PCIe 4.0 x16

Quantization and context

Quantization trades a little quality for a lot of VRAM. On 24 GB you can fit roughly a 38B model at Q4_K_M, about a 20B model at the higher-quality Q8, or a smaller model at full FP16. Longer context windows also consume VRAM (the KV cache grows with context length), so leave a few GB of headroom if you plan to use large prompts or many concurrent requests. For most chat and coding use, Q4_K_M on this card is the sweet spot between speed, quality, and the 24 GB budget.

Bottom line

The RTX A5500 is best for llm-inference, image-gen, comfyui. With 24 GB+ it comfortably handles most open models, including 30B-class at Q4. If you need more, compare with AMD Radeon RX 7900 XTX and Arc Pro B60.
