AMD EPYC8004/9004 Series Processors

Advancing Data Center
Performance and Efficiency 

EPYC by the Numbers

4th Gen AMD EPYC processors can use up to 96 cores per processor to drive faster time to results, achieve quicker insights, and enjoy better business outcomes. For performance per watt, there is an estimated 24% more integer performance and ~52% more floating-point performance than previous CPU generations at the same core count.

Advancing Processor Architecture 

For three processor generations, AMD's innovative, hybrid multi-die architecture has enabled them to leap ahead of the competition in core density and performance. The process technologies between CPU and I/O functions  have been decoupled so that each can advance at its own pace. This means delivering more innovations to your data center quickly. AMD's innovation delivers the world’s highest-performing server CPUs with the highest estimated performance per core available anywhere, all based on AMD's ‘Zen 4’ design

and 5nm process technology.


The heart of the AMD Infinity Architecture is a leadership interconnect that supports extraordinary levels of scale at every layer. Components communicate using AMD Infinity Fabric™ technology—a connection that is used within cores, between cores, and with off-chip components—to connect ‘Zen 4’ processor cores, memory, PCIe® Gen 5 I/O, and security mechanisms. As a result, the architecture delivers breakthrough performance and efficiency to deliver on the promise of next-generation computing.


An all-in philosophy means that every offering in the product line has the same built-in features. This takes the mystery out of CPU selection. Just choose the core count, cache size, and frequency your workload requires, and the rest are included at no extra cost. AMD's system-on-chip design means that servers don’t have to include additional chip sets to handle I/O, helping reduce complexity and power consumption.


The core CPU design is constantly being improved to deliver more instructions per cycle, implement new instructions, improve energy efficiency, and incorporate more hardening against security attacks. AMD's ‘Zen 4’ core helps drive 2.1x the integer and 2.2x the floating-point top-of-stack performance compared to our prior-generation processors. All based on AMD's ‘Zen 4’ design and 5nm process technology.
