Pricing

Ryzen 5900x at 550$ VS 3900x at former pricing of 500$. Ryzen 5800x will be an eight-core 16 thread part starting at 450$. Ryzen 5600x is the six core 12 thread part at 350$. AMD r9 5950x which is the 3950x replacement this CPU is a 16 core 32 thread part that claims boost up to of 4.9 gigahertz.

AMD officially announced Zen 3 architecture Ryzen 5000 series CPUs will be available on November 5th.

Naming

A naming scheme has moved to the 5000 for a reason that wouldn’t mess up the already released 4000 APUs series OEM only and only for mobile devices. They are skipping 4000 series naming to avoid confusing everybody with high-end desktop CPUs.

Significant changes 

The Ryzen 5000 series CPUs are chiplet design and are the same as before with the major difference that they unified eight-core 32-megabyte L3 cache structure which zen 2 was previously running 4+4 configuration with half the cache available on each CCX (CPU complex or core complex) there are also latency improvements and effective improvements in memory latency. 

With the 5950x we are going to have two CCDs (Core Chiplet Dies consists of two CCXs paired together using the Infinity Fabric Interconnect) active that gives you 16 cores which theoretically improve gaming performance over predecessors. 

New core layout (brings all core on the unify 8 core complex which accelerates core to core communications for better gaming workloads – lower latency)

Based on that AMD claimed the best gaming performance CPU and has taken the crown from Intel which intel has held for a long time. But Intel still leads in some workstation applications and in some cases for applications that were specifically optimized for Intel CPUs. 

Power consumption

Zen 3 architecture does not increase their power consumption with no change in socket power and no change in TDP (thermal design power) they are getting greater efficiency through better architecture design. With AMD Ryzen 5950X, AMD Ryzen 5900X,AMD Ryzen 5800X 105 watt TDP and AMD Ryzen 5600X 65W TDP. 

We might expect a small reduction in overclocking headroom or gains as a result of changes to the CCX 5000 series. 

Motherboards support

Ryzen 5000 series CPUs will be supported on the x570 and b550 motherboards there is already BIOS rollout for those. The 400 series like b450 and x470 motherboards support is planned and coming out in beta version in January of 2021. 

“Where Gaming Begins” AMD Zen 3 Reveal

Multistep AMD strategy to best desktop processors was a multistep from first gen to third-gen Ryzen now Zen 3.

Summary:

AMD currently is claiming a 19% IPC uplift over zen 2 and also claims a 21 uplift in a league of legends over the Intel 10900k and because League of Legends is a heavily CPU bound we can see the bigger difference in performance leap if the claims turn out true. Where AMD previously seriously struggled to match Intel in gaming performance it almost caught up with the Intel with Zen 2 generation and now it claims to even surpass his major competition in third-gen Zen.

AMD claims from the official presentation:

  • Best single-threaded performance
  • Best gaming performance
  • Zen3 is the most significant architecture upgrade across the Zen family
  • 24% better efficiency vs the prior generation
  • Significant IPC uplift 19% better performance across applications
  • 19% higher instructions per clock

Zen 3 Features

  • Zen 3 architecture uses 7nm lithography
  • New cache topology
  • Zen 4 will use 5nm lithography 
  • Zero bubble branch prediction
  • Twice the l3 cache 32 MB because many games have a dominant thread and that makes especially heavy use of cashing.

Cinebench score from official presentation

Cinebench score 5900x (record), 1t run 631 score, vs competition i9 – 10900k 544 score

Wait for third-party benchmarks

Although first-party benchmarks look promising you should wait for third-party independent benchmarks which should be out around November 5th on the release date of the new Ryzen Zen 3, 5000 series CPUs.
