Start with the model and serving stack, context length, concurrent sessions, latency target, tool execution, and deployment scale. Then size GPU memory and compute together with host CPU, system memory, storage, PCIe topology, and networking. Validate the candidate with a representative benchmark before committing.
Why agentic workloads change the server decision
An agent commonly cycles through reasoning, a tool call, a tool result, and another model invocation. That loop can keep sessions active longer than a single request-and-response interaction, while accumulated conversation and tool results can increase context and KV-cache demand. Tool execution, retrieval, sandboxing, and data movement also consume host resources outside the GPU.

NVIDIA describes agent tasks on its agentic inference page as involving 50–500 sequential model invocations and says agentic applications can generate up to 15 times more inference tokens. Those are NVIDIA’s vendor claims about the workloads it discusses, not universal rates for all agents. The same page gives 30K–120K+ tokens as a context range for agentic inference and estimates approximately 16–32 GB of KV cache for a 128K-token context with a 70B model. Treat that memory estimate as NVIDIA’s example, not a substitute for calculating cache needs for your model, precision, and serving implementation.

Define the workload before selecting hardware
Write down the operating profile you want a server to handle. A useful specification includes:
- Model and serving stack: the model or models, precision or quantization, tokenizer, inference backend, and serving framework.
- Session shape: context length, typical and peak prompt sizes, output lengths, and how much context tends to accumulate over a task.
- Load: typical and peak concurrent sessions, expected throughput, and whether the target is requests, sessions, or completed tasks.
- Latency: target time to first token and token-generation latency, including acceptable delays when tools run.
- Agent execution: the tools agents call, retrieval requirements, sandboxing, and whether those processes share the inference host or use separate CPU capacity.
- Deployment constraints: single node or cluster, data locality and privacy, power, cooling, rack space, and operational requirements.
These inputs determine whether a compact CPU system is sufficient, a GPU server is needed, or a distributed deployment is appropriate. They also give you a benchmark profile that reflects the intended workload rather than an unrelated vendor demonstration.

Size memory and compute for active sessions
GPU memory: weights are only part of the requirement
Estimate model memory for the actual precision or quantization and serving implementation. Then account for the KV cache of active sessions: longer contexts and more simultaneous sessions can raise memory pressure even when the model weights fit on the GPUs. Confirm that the chosen serving stack supports the intended model, memory configuration, and deployment pattern.

Host CPU and system memory: account for work around inference
Host resources may be needed for orchestration, retrieval, tool execution, sandboxed processes, and feeding data to GPUs. If those jobs compete with model serving for CPU or memory, a GPU that looks adequate on paper may not deliver the desired end-to-end response. AMD’s agentic AI guidance describes CPU roles in sandboxing, GPU host-node throughput, and general-purpose agent work; it also cautions that capacity depends on workload, model, memory, software, orchestration, and configuration.
PCIe, storage, and networking: check the whole path
GPU count alone does not describe a server’s data path. Check CPU-to-GPU balance, PCIe lanes and root complexes, NIC and NVMe placement, local storage, and inter-node networking if the design spans servers. For a cluster, network capacity and data movement can become part of inference performance; for a single node, storage and local data access still matter.

Choose a deployment size that fits the workload
AMD’s EPYC 9005 inference guidance maps CPU-only systems to small or medium models and some less latency-sensitive cases, CPU-plus-GPU systems to larger models or faster response targets, and clusters to large-scale or complex multi-agent pipelines. AMD includes expert agents among workloads suited to CPU and CPU-plus-GPU options. These are vendor’s directional categories; actual performance depends on workload and configuration, so do not treat the model-size or latency ranges on that page as universal cutoffs.
| Deployment option | When it may fit | What to validate |
|---|---|---|
| CPU-only server | Small or medium models, or work where latency is less sensitive, in AMD’s guidance. | Model fit, achieved latency and throughput, and CPU capacity for concurrent orchestration and tools. |
| CPU-plus-GPU server | Larger models or faster response targets, in AMD’s guidance; a single-node option when GPU inference is required. | GPU memory for weights and active-session cache, CPU/GPU balance, PCIe topology, and contention from agent-side processes. |
| GPU cluster | Large-scale deployments or complex multi-agent pipelines, in AMD’s guidance. | Distributed-serving support, inter-node network, data movement, scale behavior, and whether the cluster meets latency and task-completion goals. |
Use the table as a shortlist, not a sizing formula. A server choice should satisfy the model-and-memory fit, latency and throughput targets, agent-execution needs, topology, operational constraints, and economics together. Compare acquisition and operating costs per useful completed task rather than peak throughput alone; the sources cited here do not establish a neutral total-cost comparison.
Benchmark candidates with a representative agent workload
Do not choose from a single peak-throughput number. Test the intended model and backend with realistic prompt and output lengths, target context, concurrency, tool pauses, and cache state. Record time to first token, inter-token latency, throughput or goodput, resource use, and successful task completion where possible. Include the actual tool and retrieval path if those components are part of the deployment; a model-only test cannot establish end-to-end agent performance.
For results that can be compared or repeated, record the model, tokenizer, backend, container image, hardware profile, network mode, storage path, prompt and output profiles, concurrency, cache state, and software versions. NVIDIA lists these provenance details in its inference reference architecture. AMD’s EPYC/Nutanix user guide describes varying input and output token lengths and simulated parallel users, then measuring per-token latency, time to first token, throughput, and CPU and memory utilization. These are useful measurement templates, not evidence that one benchmark represents every agent workflow.
Vendor benchmarks can help identify candidate configurations, but they are not independent cross-vendor verdicts. For example, AMD’s EPYC 9005 host-CPU results describe a particular system, software, memory, and BIOS setup; AMD states the testing was as of 2025-10-24. Treat such results as configuration-specific vendor tests and reproduce the workload on the system you are considering.
Quick Recap
Use a decision checklist before ordering
- Specify the workload: list model, precision or quantization, framework, context and prompt/output distributions, session concurrency, latency and throughput targets, and tool workload.
- Estimate per-session and aggregate memory: account for model memory and KV cache using the intended model and serving implementation, then assess active-session peaks.
- Choose the deployment shape: assess CPU-only, CPU-plus-GPU, and cluster options against model fit, latency, scale, and agent-side CPU demand.
- Verify the system topology: check GPU-to-CPU balance, PCIe connectivity, memory, local storage, NIC placement, and network capacity against the selected platform’s validated guidance.
- Run a representative test: use realistic concurrency, cache conditions, context, and tool pauses; capture latency, throughput, resource use, and task completion.
- Keep benchmark provenance: record hardware and software versions, model and tokenizer, backend, network and storage paths, prompt profile, output profile, concurrency, and cache state.
- Compare operational fit: assess software support, security, manageability, power, cooling, space, and cost per completed task alongside model performance.
