Cisco Processors

Renewtech supplies refurbished Cisco processors that are tested, certified, and in stock for fast rollout. Equip your Cisco UCS servers with CPUs that are fully compatible and ready to install—without tying up budget in new hardware. This keeps projects on schedule, extends the life of existing hosts, and reduces environmental impact by avoiding unnecessary new production. We deliver quickly across the UK, including London, Manchester, Birmingham, and Glasgow, as well as Europe and worldwide.

We serve organisations of every size—data centres, hosting providers, SaaS platforms, manufacturers, the public sector, and service businesses. Every refurbished Cisco CPU is inspected by certified technicians, validated under real workloads, and packaged for safe installation. With hundreds of units on the shelf, you can upgrade nodes and add capacity without delays.

If you’re sizing a complete build, use the Cisco Server Configurator to match processors with memory, storage, RAID, and networking across the same platform, so your cluster lands on a consistent stepping and firmware baseline.

Cisco CPUs for Business Workloads

Cisco UCS platforms are designed to run demanding business workloads without interruption. Whether you’re managing virtualisation clusters, large databases, analytics, VDI pools, or private and hybrid cloud environments, the CPU determines both stability and throughput. The right Cisco processor prevents bottlenecks, supports smooth scaling, and ensures that mission-critical services remain responsive even during peak demand.

Refurbished Cisco processors deliver reliable performance where it matters most. With high core density, they handle parallel workloads efficiently. Large cache sizes cut latency in data-intensive applications, while their stable thermal behaviour integrates seamlessly with UCS cooling profiles. That makes them an excellent choice for businesses balancing performance requirements with energy efficiency and long-term costs.

Many companies extend the lifecycle of their Cisco UCS infrastructure by upgrading CPUs instead of replacing entire systems. Swapping processors boosts performance while keeping existing chassis, mezzanine cards, and storage arrays intact. This approach maintains cluster parity, reduces downtime, and avoids unnecessary requalification work—while saving significantly on costs.

Intel Xeon in Cisco UCS: Platinum, Gold, Silver, Bronze

Cisco UCS servers commonly run Intel Xeon processors across clear performance tiers that align with workload and budget needs:

• Platinum – for compute-heavy, dense multi-socket nodes

• Gold – balanced performance for virtualisation, analytics, and large databases

• Silver / Bronze – reliable options for backup roles, essential services, and cost-sensitive workloads

Not sure about the differences between Platinum, Gold, Silver, and Bronze CPUs? The Intel CPU Naming Convention Guide gives you a straightforward overview to help match the right processor to your Cisco servers.

Cisco CPU Availability and Compatibility

Our Cisco CPU stock reflects the way businesses actually plan upgrades. You’ll find everything from compact 4–8 core models for lighter workloads to 12, 16, 24 cores and beyond for dense virtualisation clusters. Popular clock speeds in the 1.7–2.6 GHz range are well covered, alongside both legacy and current CPU families to keep mixed UCS generations aligned. With over 200,000 items in stock and rapid access to additional parts through our partner network, you won’t need to delay a rollout waiting for a specific stepping or FRU.

Every refurbished Cisco processor is verified for compatibility before shipping. That means checking part numbers against Cisco support matrices, aligning sockets, and confirming BIOS, firmware, and memory requirements. In practice, the CPU you receive fits immediately, posts cleanly, and performs as expected—so you avoid wasted time on mismatched components.

This combination of wide stock and hands-on compatibility checks ensures your projects stay on track. Whether you’re refreshing a single UCS rack server or upgrading across an entire cluster, you can move forward with confidence.
