What is FPGA for AI?
FPGAs provide reconfigurable hardware for AI inference enabling custom architectures and low-latency deployment. FPGAs fill niche between ASICs and GPUs for specialized inference workloads.
This AI hardware and semiconductor term is currently being developed. Detailed content covering technical specifications, performance characteristics, use cases, and purchasing considerations will be added soon. For immediate guidance on AI infrastructure strategy, contact Pertama Partners for advisory services.
FPGAs occupy a specific performance niche between GPUs and ASICs, delivering deterministic low-latency inference essential for applications where milliseconds of additional delay create measurable business impact. Financial services organizations deploy FPGAs for algorithmic trading and fraud detection where microsecond response times directly translate to captured revenue opportunities. The technology enables edge AI deployment in Southeast Asian manufacturing facilities, telecommunications towers, and agricultural monitoring stations with constrained power budgets. Organizations should evaluate FPGA investment only when latency requirements below 1ms are validated by business case analysis, since GPU-based alternatives provide superior cost-per-inference for all other workload profiles.
- Reconfigurable logic vs fixed ASIC design.
- Low latency for real-time inference.
- Custom architecture optimization.
- More flexible than ASIC, less than GPU.
- Power efficiency between GPU and ASIC.
- Niche: ultra-low latency, specialized workloads.
- FPGAs provide sub-microsecond inference latency impossible with GPU-based solutions, making them essential for high-frequency trading and real-time control system applications.
- Development requires specialized HDL programming skills commanding $120,000-180,000 annual compensation, limiting FPGA adoption to organizations with specific latency requirements.
- Power consumption 5-10x lower than equivalent GPU solutions reduces operational costs for edge deployment scenarios where energy availability constrains compute capacity.
- Xilinx Alveo and Intel Stratix accelerator cards provide pre-built AI inference overlays reducing development effort from months to weeks for standard model architectures.
- Reconfigurability enables updating deployed hardware for new model architectures without physical replacement, extending useful hardware lifetime beyond fixed ASIC alternatives.

Common Questions
Which GPU should we choose for AI workloads?
NVIDIA dominates AI with H100/A100 for training and A10G/L4 for inference. AMD MI300 and Google TPU offer alternatives. Choose based on workload (training vs inference), budget, and ecosystem compatibility.
What's the difference between training and inference hardware?
Training needs high compute density and memory bandwidth (H100, A100), while inference prioritizes latency and cost-efficiency (L4, A10G, TPU). Many organizations use different hardware for each workload.
More Questions
H100 GPUs cost $25K-40K each, typically deployed in 8-GPU nodes ($200K-320K). Cloud rental is $2-4/hour per GPU. Inference hardware is cheaper ($5K-15K) but you need more units for serving.
