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.
