Choose AMD EPYC 9965 (Turin / Zen 5) if...
You need maximum core density for virtualisation, cloud-native workloads, or HPC. The EPYC 9965 Turin offers 192 cores per socket with 12-channel DDR5-6000 and 128 PCIe 5.0 lanes, giving it a substantial advantage in multi-threaded throughput and memory bandwidth.
Choose Intel Xeon 6980P (Granite Rapids) if...
You need high per-core performance for latency-sensitive workloads like real-time databases, financial trading applications, or per-core-licensed software. Intel's Xeon 6 P-cores offer strong single-threaded performance, and MCR DIMMs provide exceptional memory bandwidth per channel.

Frequently Asked Questions
What are the key architectural differences between Turin and Granite Rapids?
AMD EPYC Turin uses the Zen 5 architecture with chiplet design, offering up to 192 cores per socket with 12 DDR5 channels. Intel Granite Rapids uses a monolithic or tiled approach with up to 128 cores, 8 MCR DDR5 channels (using MRDIMMs for higher bandwidth per channel). Turin leads in core count and PCIe lanes, while Granite Rapids focuses on memory bandwidth per channel.
Which platform is better for AI inference in 2026?
Both platforms include built-in AI acceleration. AMD EPYC Turin includes AVX-512 with VNNI extensions, while Intel Xeon 6 includes AMX (Advanced Matrix Extensions) for INT8/BF16 matrix operations. For CPU-based AI inference without GPUs, Intel AMX generally provides better inference throughput per core.
Are both platforms available in India in 2026?
Yes. Both AMD EPYC 9005 (Turin) and Intel Xeon 6 (Granite Rapids) are available through major server OEMs in India. Supermicro, Dell, HPE, and Lenovo all offer platforms based on both processors.
