Let’s dive into the details:

Zen 4 Recap

Before we delve into Zen 5, let’s quickly recap Zen 4. This architecture powers AMD’s current server, desktop, and mobile segments. Zen 4 brought notable enhancements, including increased cache sizes, higher clocks, and improved instructions per clock (IPC) performance.

The Zen 5 Leap

Now, let’s talk about Zen 5:

  1. IPC Boost: Zen 5 is expected to deliver an IPC uplift of 15-24% compared to Zen 3. This means better performance per clock cycle, translating to faster execution of instructions.

  2. Clock Speeds: Zen 4 prototypes have already hit clock speeds of up to 5.2 GHz. Expect sustained clock boosts of 8-14% over Zen 3.

  3. Cache Improvements: Zen 5 doubles the L2 cache size while retaining the same L3 cache as Zen 3. This enhances memory access and overall performance.

  4. I/O Enhancements: Zen 5 introduces support for PCIe 5.0, DDR5, and LPDDR5 memory. These advancements will boost data transfer rates and responsiveness.

  5. AVX-512 Performance: Zen 5’s AVX-512 performance is comparable to Intel’s Ice Lake-X and significantly better than Zen 3.

Product Lineup

AMD’s Zen 4 lineup includes:

  • EPYC Genoa 7004: Expected in Q4 2022, this server CPU promises impressive performance.
  • Ryzen 7000 ‘Raphael’: Samples are already running, with production soon.

Zen 5’s Arrival

AMD confirms that Zen 5 is on track for the consumer market by the second half of 2024. The architecture will power upcoming AMD Kraken Point APUs, combining regular Zen 5 cores with power-efficient Zen 5c cores.

In summary, Zen 5 is poised to be a leap forward, offering better IPC, higher clock speeds, and improved cache management. As we eagerly await its arrival, AMD continues to push the boundaries of CPU performance.
