Zen 3 is the codename for a CPU microarchitecture by AMD, released on November 5, 2020.[1][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 (as it did with the Ryzen 3000XT processors).[6] Zen 3 powers Ryzen 5000 mainstream desktop processors (codenamed "Vermeer") and Epyc server processors (codenamed "Milan").[7][4] Zen 3 is supported on motherboards with 500 series chipsets; 400 series boards will also see support on select B450 / X470 motherboards with certain beta BIOSes.[8] Zen 3 is expected to be the last microarchitecture before AMD switches to DDR5 memory and new sockets.[3] According to AMD, Zen 3 has a 19% higher instructions per cycle (IPC) on average than Zen 2.
Features
Zen 3 is a significant incremental improvement over its predecessors, with an IPC increase of 19%,[9] and being capable of reaching higher clock speeds.
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 each as well as 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.[9]
Zen 3 also features Smart Access Memory (SAM), a technology allowing Zen 3 processors to directly access all of a compatible graphic card's VRAM.[10] According to AMD, this allows an increased FPS of up to 11% in certain games.[11] SAM is an implementation of Resizable BAR, an optional feature introduced in PCIe 2.0 that, as of the launch of Zen 3, only AMD has explored.[12] As of December 2020, Intel and Nvidia are reportedly working on implementing Resizable BAR in the near future.

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.[2]
Improvements
![[icon]](/wiki/File:Wiki_letter_w_cropped.svg){kind=small} | This section needs expansion with: list of improvements, paraphrased. You can help by adding to it. (November 2020) |
Zen 3 has made the following improvements over Zen 2:[2][13]
- An increase of 19% in instructions per clock
- The base core chiplet has a single eight-core complex (versus two four-core complex in Zen 2)
- A unified 32MB L3 cache pool equally available to all 8 cores in a chiplet, vs Zen 2's two 16MB pools each shared among 4 cores in a core complex.
- Increased branch prediction bandwidth. L1 branch target buffer size increased to 1024 entries (vs 512 in Zen 2)
- Improved integer units
- 96 entry integer scheduler (up from 92)
- 192 entry physical register file (up from 180)
- 10 issue per cycle (up from 7)
- 256 entry reorder-buffer (up from 224)
- fewer cycles for DIV/IDIV ops (10...20 from 16...46)
- Improved floating point units
- 6 µOP dispatch width (up from 4)
- 4 cycles for fused-multiply-add-ops (down from 5)
