Have you ever thought that older GPUs might help you reduce costs while boosting AI performance? In this case study, a global bank turned unused office desktops and servers into a powerful, distributed GPU network. By using Rafay’s Kubernetes-based orchestration and reliable NVIDIA hardware, the proof of concept improved throughput, cut render time, and significantly lowered monthly costs. This example shows how repurposing legacy compute resources can drive efficiency and deliver clear cost savings for large enterprises.
GPU Workload Transformation Case Study Overview

A global bank recently ran a proof of concept to turn underused GPUs from office desktops and servers into a powerful, distributed GPU swarm. They used NVIDIA RTX 4500, RTX 4090, and dual RTX 6000 Ada to convert old hardware into a high-performance AI engine. We managed this work with Rafay’s orchestration platform and put the new setup to the test using real-world inference workloads. The goal was to show clear performance gains compared to traditional cloud GPU services.
Our approach with Rafay streamlined the transition from legacy compute resources to a multi-tenant GPU swarm. The idea was to measure key metrics like tokens per second throughput, render time (latency), and total cost of ownership (TCO) against an A100 80 GB cloud instance. We focused on improving both operational efficiency and cost savings, providing a clear blueprint for scaling AI in large enterprises.
- We first evaluated idle GPUs and overall compute needs.
- Next, we converted the infrastructure into a multi-user GPU swarm.
- Then, we deployed and managed everything through Rafay’s Kubernetes-based platform.
- Finally, we validated performance by comparing it with cloud A100 instances.
| Metric | Pre-Transformation | Post-Transformation |
|---|---|---|
| Throughput (tokens/sec) | Standard performance | +37% improvement |
| Latency (ms) | 120 ms | 85 ms |
| TCO/month (€) | Higher cost baseline | 28% reduction |
This change not only sped up inference but also cut costs significantly. By repurposing dormant hardware into a scalable, managed GPU swarm, enterprises can enjoy better throughput and lower render times while spending less every month. These improvements offer a strategic edge, allowing reinvestment in innovation and strengthening competitiveness in demanding AI environments.
Methodology and Toolchain for GPU Workload Transformation

We turned to Rafay’s GPU platform-as-a-service because it efficiently manages both GPU (graphics processing unit) and CPU resources. In our tests, integrating the platform with Kubernetes (a system for automating application deployment) not only streamlined resource use but also turned idle GPUs into a production-ready compute cluster. When a new AI workload starts, the system quickly checks for available GPUs and assigns one, significantly cutting setup time.
Key capabilities include:
- Multi-tenant GPU cloud provisioning
- Automated workload scheduling and scaling
- Serverless inference support
- Kubernetes cluster lifecycle management
- Policy-driven cost and security enforcement
- Hybrid-cloud deployment orchestration
These features worked together to boost our benchmarks. Leveraging Kubernetes to match resources with job demands, we saw a 2.5x improvement in resource utilization. This approach turns underused hardware into managed compute power while automating workload scheduling and keeping costs in check.
Performance Metrics from the GPU Workload Transformation Case Study

In our tests, we measured tokens processed per second (throughput), delay when handling 1,000 simultaneous inference requests (latency), and the monthly total cost of ownership (TCO) using an A100 80 GB cloud instance. These figures not only show raw performance but also reflect the real-world benefits for dynamic workloads.
| Metric | Pre-Transformation | Post-Transformation |
|---|---|---|
| Throughput (tokens/sec) | Standard performance | +37% improvement |
| Latency (ms) | 120 ms | 85 ms |
| TCO/month (€) | Higher cost baseline | 28% reduction |
The 37% boost in throughput shows that pooling idle GPUs into a network means they now process more tokens per second, which speeds up model inference overall. The drop in latency from 120 ms to 85 ms makes a big difference in real-time tasks like visualization or quick decision making. For instance, when every millisecond matters, an 85 ms response can be the key to smooth, uninterrupted simulation. Moreover, a 28% drop in monthly TCO proves that using idle GPU resources effectively reduces operational costs during peak compute times. These improvements are especially valuable when GPUs are running at around 75% capacity, highlighting the advantage of a distributed processing approach in enterprise settings.
Cost Efficiency Analysis of the GPU Workload Transformation

We break down how to cut costs when switching work to GPUs (graphics processing units). Lowering total cost of ownership (TCO) is key. Smart TCO management lets you turn unused hardware into a strong asset. When you repurpose idle desktops and servers into powerful GPU swarms, you avoid the high price of cloud-based instances. This means you spend less and free up funds for innovation.
We base our method on three main points:
- Spreading hardware costs over 36 months.
- Using energy priced at €0.18 per kilowatt-hour with measurable efficiency gains.
- Comparing expenses with the rental rates of cloud-based GPU instances, as detailed in the linked comparison.
Using this cost-calculation approach, businesses can see clear savings. Our analysis shows that lowering the use of expensive cloud GPUs leads to major savings. Repurposing existing hardware reduces upfront capital outlay and improves operating costs. This balanced strategy paves the way for reinvesting in new technology and talent while supporting steady growth in GPU-intensive environments.
Best Practices and Lessons Learned in GPU Workload Transformation Case Study

We understand that tackling challenges like secure access, network setup, and identity management is essential when updating GPU (graphics processing unit) workloads. To overcome these hurdles, we integrated enterprise identity services that enable secure, multi-user access without any extra hardware. This solution helped turn idle GPUs into true revenue-generating assets while keeping security, cost control, and compliance in check.
Here are the key steps we followed:
- Conduct a complete inventory of idle GPU assets.
- Use Kubernetes (K8s) for dynamic scaling.
- Enforce cost and security policies with platform guardrails.
- Automate lifecycle management and monitoring.
- Validate performance using real-world tasks before full rollout.
These best practices not only eased the transformation process but also created a proactive framework for future changes. By learning from initial challenges and applying these clear steps, you can streamline GPU transitions and boost operational efficiency for evolving AI workloads.
Future Directions for GPU Workload Transformation and Scalability

GPU management and cloud speed are changing fast. Companies now use multi-cloud systems (like Amazon EKS, Microsoft AKS, Google GKE, Oracle OKE) along with on-premise and public cloud setups. This blend of legacy infrastructure with modern GPU platforms offers a chance for big efficiency gains. New developments such as serverless model inference and shared GPU platform services with NVIDIA are speeding up these changes.
We are focusing on:
- Growing serverless GPU model inference.
- Improving multi-cloud failover and cutting costs.
- Adding new AI accelerator hardware (such as DPUs and TPUs).
- Running ongoing scalability tests with different enterprise workloads.
These efforts will drive the next phase of GPU workload improvements. By moving to more flexible computing models, businesses can use resources smarter and keep up with new trends in AI and real-time processing.
