Zen 3 was not AMD’s 5nm architecture target. In March 2020, AMD planned to introduce Zen 3 processors later that year, while its stated 5nm target applied to Zen 4. AMD also planned late-2020 products using RDNA 2, the graphics architecture later identified as the foundation for both PlayStation 5 and Xbox Series S/X. The Xbox Series X uses a custom Zen 2 CPU—not Zen 3—alongside a custom RDNA 2 GPU.
What AMD’s 2020 roadmap said
AMD’s March 5, 2020 Financial Analyst Day laid out separate plans for its CPU and graphics architectures. The timing matters: the roadmap distinguished the Zen 3 processors AMD expected to introduce in late 2020 from the 5nm process target it assigned to Zen 4.
| Roadmap item | AMD’s stated plan or later confirmation |
|---|---|
| Zen 3 CPUs | AMD planned to introduce its first Zen 3 processors in late 2020. In its Q3 2020 results, it identified Ryzen 5000 desktop processors as featuring Zen 3. |
| Zen 4 process target | In March 2020, AMD said Zen 4 was in design and targeted to use advanced 5nm process technology. In its 2022 roadmap update, AMD called Zen 4 the world’s first high-performance 5nm x86 CPU generation. |
| Zen 5 timing | AMD’s 2022 roadmap placed Zen 5 on a 2024 plan; that statement was a roadmap plan, not a description of Zen 3 or its process node. |
| RDNA 2 graphics | AMD planned its first RDNA 2 products for late 2020. Its Q3 2020 results identified Radeon RX 6000 as the high-end RDNA 2 graphics launch. |
Is Zen 3 5nm?
No: the 5nm target in AMD’s March 2020 roadmap was for Zen 4, not Zen 3. AMD’s statement was explicit: “The ‘Zen 4’ core is currently in design and is targeted to use advanced 5nm process technology.” In the same announcement, AMD said it planned to introduce the first Zen 3 processors in late 2020.
AMD’s 2022 description of Zen 4 as a high-performance 5nm x86 generation reinforces that distinction. Zen 3 belongs to the earlier, 7nm-era roadmap context; the evidence here does not support describing it as a 5nm generation. Architecture generation and manufacturing process are related but separate labels: “Zen 3” names a CPU architecture generation, while “5nm” describes the process target AMD announced for Zen 4.

What did RDNA 2 add, and what did AMD claim?
RDNA 2 was AMD’s next graphics architecture, intended for both Radeon products and semi-custom console chips. In March 2020, AMD said it planned late-2020 RDNA 2 products with hardware ray tracing and variable-rate shading. It also set a target of 50% better performance per watt than first-generation RDNA.
That 50% figure was AMD’s forward-looking target, not an independently tested result or a guarantee for every RDNA 2 product. The Q3 2020 results subsequently identified Radeon RX 6000 as AMD’s high-end RDNA 2 graphics launch.

Which architectures do PS5 and Xbox Series X use?
Both consoles use AMD semi-custom SoCs, but their shared RDNA 2 graphics foundation does not mean they have identical configurations—or Zen 3 CPUs. Microsoft’s Xbox Series X specification lists a custom 8-core Zen 2 CPU and a custom RDNA 2 GPU. AMD’s 2021 annual filing describes RDNA 2 as the graphics foundation for PlayStation 5 and Xbox Series S/X, and confirms AMD developed the consoles’ semi-custom SoCs.

Microsoft’s March 16, 2020 Xbox Wire specification gives the Xbox Series X CPU as “8x Cores @ 3.8 GHz (3.6 GHz w/ SMT) Custom Zen 2 CPU” and its GPU as “12 TFLOPS, 52 CUs @ 1.825 GHz Custom RDNA 2 GPU.” These are console-specific specifications, not general specifications for every Zen 2 or RDNA 2 product.
Rank #3
- Can deliver fast 100 plus FPS performance in the world's most popular games, discrete graphics card required
- 6 Cores and 12 processing threads, bundled with the AMD Wraith Stealth cooler
- 4.2 GHz Max Boost, unlocked for overclocking, 19 MB cache, DDR4-3200 support
- For the advanced Socket AM4 platform
PlayStation 5 and RDNA 2
The cited AMD materials establish that PS5 uses AMD’s semi-custom SoC and that RDNA 2 is a graphics foundation for the console. They do not provide PS5 CPU or GPU clock and compute-unit figures here, so Xbox Series X specifications should not be applied to PS5.

How to interpret the roadmap without mixing up the generations
- CPU architecture: Zen 3 was the late-2020 processor generation AMD planned; Zen 4 was the generation AMD associated with its 5nm target.
- GPU architecture: RDNA 2 was a separate graphics roadmap item, with Radeon RX 6000 as the high-end desktop graphics launch and console implementations in semi-custom SoCs.
- Console implementation: Xbox Series X pairs a Zen 2 CPU with an RDNA 2 GPU. The consoles’ RDNA 2 relationship does not make their CPUs Zen 3.
- Performance claims: AMD’s 50% performance-per-watt figure was a target versus first-generation RDNA, not a universal measured result.
