AMD dives deep into Zen 4 and discusses Zen 5 at their Financial Analyst Day

AMD has revealed a lot of new information about their Zen 4 CPU architecture

AMD has revealed a lot of new information about Zen 4 at their Financial Analyst Day. We have already talked about AMD's CPU roadmap (here), but that was not the only thing that AMD discussed with regards to their CPUs. 

Zen 4 is launching this year with 4th Generation EPYC and Ryzen 7000 series processors, and AMD has promised users "significant generational performance-per-watt and frequency improvement", a change that will be music to the years that desire more performance "frequency improvements", and increased power efficiency "performance-per-watt". 

With Zen 4, AMD has now promised an 8-10% IPC improvement over Zen 3, and a greater than 15% single-threaded performance gain over Zen 3. Heightened IPC will allow AMD to deliver more performance per clock cycle, and increased clock speeds will allow AMD's Zen 4 cores to complete more clock cycles per second. Together, these changes will deliver significant performance increases across a variety of applications.

AMD's Zen 4 processors will also offer users more memory bandwidth per core thanks to AMD's support for ultra-fast DDR5 memory. Additionally, AMD's Zen 4 architecture now features AI instructions and AVX-512 support.

At Computex, AMD showcased a desktop Ryzen 7000 series Zen 4 processor that had 16 CPU cores running at 5+ GHz and peak frequencies of above 5.5GHz. That's a huge frequency gain over today's Zen 3 CPU models.

The slide below showcases how AMD's Zen 4 16-core desktop CPU can deliver more than 25% performance per watt gains over an equivalent Zen 3 processor, and a 35% increase in overall performance. In short, AMD's Zen 4 desktop processors will deliver higher efficiency levels than Zen 3, and higher wattages for premium products will result in larger performance gains in all-core workloads.

Zen 5 is coming in 2024

AMD has confirmed that Zen 5 is coming in 2024, promising higher levels of performance and power efficiency than Zen 4, a re-pipelined front end and wider issue. Alongside these changes, AMD will be integrating new AI and machine learning optimisations. 

Sadly, AMD has not revealed a lot of useful information about Zen 5. Increased efficiency and performance are expected changes for Zen 5, but it is good to know that we should expect Zen 5 to launch in 2024. AMD's desktop Zen 5 processors should be compatible with AMD's upcoming AM5 motherboards, giving Zen 4 users a clear upgrade path in 2025.

Not as impressive when you realize they are comparing to non V-Cahce CPUs. I'd like to see those comparisons included next time from them.

Still I'd like to upgrade to Zen 4. Just gotta wait for ddr5 ro finally be reasonableQuote

Yeah, AMD is facing a lot tighter competition now. Alder Lake is faster in IPC in many workloads than Zen 3 (not gaming when compared to 5800X3D), and Zen 4 might only match it or slightly beat it. Intel then will release Raptor Lake and retake that crown. I'm still very impressed by Zen 4 though.Quote
