Zen 3 is the name for a CPU microarchitecture by AMD, released on November 5, 2020. [2] [3] It is the successor to Zen 2 and uses TSMC's 7 nm process for the chiplets and GlobalFoundries's 14 nm process for the I/O die on the server chips and 12 nm for desktop chips. [4] Zen 3 powers Ryzen 5000 mainstream desktop processors (codenamed "Vermeer") and Epyc server processors (codenamed "Milan"). [5] [6] Zen 3 is supported on motherboards with 500 series chipsets; 400 series boards also saw support on select B450 / X470 motherboards with certain BIOSes. [7] Zen 3 is the last microarchitecture before AMD switched to DDR5 memory and new sockets, which are AM5 for the desktop "Ryzen" chips alongside SP5 and SP6 for the EPYC server platform and sTRX8. [3] According to AMD, Zen 3 has a 19% higher instructions per cycle (IPC) on average than Zen 2.

Contents

On April 1, 2022, AMD released the new Ryzen 6000 series for laptops/mobile, using an improved Zen 3+ architecture featuring notable architectural improvements to power efficiency and power management. [8] And slightly later, on April 20, 2022, AMD would also release the Ryzen 7 5800X3D desktop processor, which increased gaming performance by around +15% on average by using for the very first time in a PC product, a 3D vertically stacked L3 cache. Specifically in the form of a 64MB L3 cache "3D V Cache" die made on the same TSMC N7 process as the 8-core Zen 3 CCD which it gets direct copper to copper hybrid bonded to. [9]

Features

As the first largely "ground up redesign" of the Zen CPU core since the architecture family's original release in early 2017 with Zen 1/Ryzen 1000, Zen 3 was a significant architectural improvement over its predecessors; having a very significant IPC increase of +19% over the prior Zen 2 architecture in addition to being capable of reaching higher clock speeds. [10]

Like Zen 2, Zen 3 is composed of up to 2 core complex dies (CCD) along with a separate IO die containing the I/O components. A Zen 3 CCD is composed of a single core complex (CCX) containing 8 CPU cores and 32 MB of shared L3 cache, this is in contrast to Zen 2 where each CCD is composed of 2 CCX, each containing 4 cores paired with 16 MB of L3 cache. The new configuration allows all 8 cores of the CCX to directly communicate with each other and the L3 Cache instead of having to use the IO die through the Infinity Fabric. [10]

Zen 3 (along with AMD's RDNA2 GPUs) also implemented Resizable BAR, an optional feature introduced in PCIe 2.0, that was branded as Smart Access Memory (SAM). This technology allows CPU to directly access all of compatible video card's VRAM. [11] Intel and Nvidia have since implemented this feature as well. [12]

In Zen 3, a single 32MB L3 cache pool is shared among all 8 cores in a chiplet, vs. Zen 2's two 16MB pools each shared among 4 cores in a core complex, of which there were two per chiplet. This new arrangement improves the cache hit rate as well as performance in situations that require cache data to be exchanged among cores, but increases cache latency from 39 cycles in Zen 2 to 46 clock cycles and halves per-core cache bandwidth, although both problems are partially mitigated by higher clock speeds. Total cache bandwidth on all 8 cores combined remains the same due to power consumption concerns. L2 cache capacity and latency remain the same at 512KB and 12 cycles. All cache read and write operations are done at 32 bytes per cycle. [13]

On April 20, 2022, AMD released the R7 5800X3D. It features, for the first time in a desktop PC product, 3D-stacked vertical L3 cache. Its extra 64MB comes via a TSMC N7 (7nm) "3D V Cache" die direct copper to copper hybrid bonded right on top of the 8-core Zen 3 CCD's usual 32MB, increasing the CPU's total L3 cache capacity to 96MB and bringing significant performance improvements for gaming in particular; now rivalling contemporary high-end consumer processors while being much more power efficient and running on older, cheaper motherboards using affordable DDR4 memory. [9] And despite now spanning multiple dies and being three times larger (96MB vs 32MB), the L3 cache's performance remains nearly identical; with X3D only adding around ≈+2ns via an additional three to four cycles of latency. [14] It would later be followed by the Ryzen 5 5600X3D and Ryzen 7 5700X3D for lower-end market segments, and succeeded by the Ryzen 7000X3D family of 3D V Cache equipped Zen 4 processors on the newer socket AM5 platform.

    Zen 3+ is the codename for a refresh of the Zen 3 microarchitecture, which focuses on power efficiency improvements. It was released in April 2022 with the Ryzen 6000 series of mobile processors.

    Features and improvements

    Zen 3+ has 50 new or enhanced power management features over Zen 3, and also provides an adaptive power management framework, as well as new deep sleep states. Altogether, this brings improvements to efficiency both during idle, and when under load, with up to 30% performance-per-watt increase over Zen 3, as well as longer battery life. [57] [58]

    IPC is identical to that of Zen 3; the performance improvements of Ryzen 6000 over Ryzen 5000 mobile processors stem from it having a higher efficiency (hence more performance in power-constrained form factors like laptops), as well as the increased clock speeds from being built on the smaller TSMC N6 node. [59]

    The Rembrandt implementation of Zen 3+ also has support for DDR5 and LPDDR5 memory.

    Products

    Rembrandt

    On April 1, 2022, AMD released the Ryzen 6000 series of mobile APUs, codenamed Rembrandt. It introduces PCIe 4.0 and DDR5/LPDDR5 for the first time in an APU for the laptop and also introduced RDNA2 integrated graphics to the PC. It is built on TSMC's 6 nm node. [8]

    Common features of Ryzen 6000 notebook APUs:

    • Socket: FP7, FP7r2.
    • All the CPUs support DDR5-4800 or LPDDR5-6400 in dual-channel mode.
    • L1 cache: 64 KB (32 KB data + 32 KB instruction) per core.
    • L2 cache: 512 KB per core.
    • All the CPUs support 16 PCIe 4.0 lanes.
    • Includes integrated RDNA 2 GPU.
