AMD EPYC 8004-series 'Siena' Processors: Specifications and Anticipated Features

@momomo_us recently disclosed potential specifications for AMD's upcoming EPYC 8004-series 'Siena' processors, based on the Zen 4 architecture. 



The AMD EPYC 8004-series 'Siena' is expected to include six models with core configurations ranging from eight to 64 cores. Anticipated clock speeds lie between 2.20 GHz and 2.55 GHz, and power consumption is projected to vary from 90W to 200W, depending on the specific model. Furthermore, the 'Siena' processors are predicted to incorporate an L3 cache of up to 128 MB, half the size of the L3 cache in AMD's 64-core EPYC 'Rome' processor.

The origin of these specifications hasn't been revealed. Still, outlets like @momomo_us generally source their details from documents associated with chip manufacturers or their partners. Although potentially derived from a credible source, the information might be preliminary or out-of-date, necessitating a cautious approach.

These specifications suggest that the EPYC 8004-series 'Siena' processors are designed for low-power servers that emphasize cost-effectiveness and simplicity over peak performance. Indicatively, the highest thermal design power (TDP) for 'Siena' is 200W, according to the new data.

It's predicted that AMD's 'Siena' processors will employ the company's new SP6 platform. This differs from the intricate SP5 platform used by the AMD EPYC 9000-series processors, which aim for maximum core counts and high performance. As an example, the SP6 platform might feature an eight-channel DDR5-4800 memory subsystem, providing sufficient bandwidth for a 64-core CPU and being less intricate than the 12-channel memory systems in AMD's Genoa, Genoa-X, and Bergamo processors.
