Succession

Zen 2 is AMD's successor to Zen+, a 7 nm process microarchitecture for mainstream mobile, desktops, workstations, and servers. Zen 2 will eventually be replaced by Zen 3.

For performance desktop and mobile computing, Zen is branded as Athlon, Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Ryzen Threadripper processors. For servers, Zen is branded as EPYC.

History

Zen 2

Zen 2 succeeded Zen in 2019. In February of 2017 Lisa Su, AMD's CEO announced their future roadmap to include Zen 2 and later Zen 3. On Investor's Day May 2017 Jim Anderson, AMD Senior Vice President, confirmed that Zen 2 was set to utilize 7 nm process. Initial details of Zen 2 and Rome were unveiled during AMD's Next Horizon event on November 6, 2018.

Core

Zen 2 largely builds on Zen. Most of the fine details have not been revealed by AMD yet.


Under construction icon-blue.svg This article is a work in progress!


Front End

In order to feed the backend, which has been widened to support 256-bit operation, the front-end throughput was improved. AMD reported that the branch prediction unit has been reworked. This includes improvements to the prefetcher and various undisclosed optimizations to the instruction cache. The µOP cache was also tweaked including changes to the µOP cache tags and the µOP cache itself which has been enlarged to improve the instruction stream throughput.

Execution Engine

AMD stated that both the dispatch bandwidth and the retire bandwidth has been increased.

Floating Point Unit

Like the Zen/Zen+ microarchitecture, the Zen 2 floating point unit utilizes a coprocessor architectural model comprising a dedicated rename unit, a single 4-issue, out-of-order scheduler, a 160-entry physical register file (PRF), and four execution pipelines. The in-order retire queue is shared with the integer unit. The FPU handles x87, MMX, SSE, and AVX instructions. FP loads and stores co-opt the EX unit for address calculations and the LS unit for memory accesses.

In the Zen/Zen+ microarchitecture the floating point physical registers, execution units, and data paths are 128 bits wide. For efficiency AVX-256 instructions which perform the same operation on the 128-bit upper and lower half of a YMM register are decoded into two macro-ops which pass through the FPU individually as execution resources become available and retire together. Accordingly the peak throughput is four SSE/AVX-128 instructions or two AVX-256 instructions per cycle.

Zen 2 doubles the width of the physical registers, execution units, and data paths to 256 bits. The L1 data cache bandwidth was doubled to match. The number of micro-ops issued by the FP scheduler remains four, implying most AVX-256 instructions decode to a single macro-op which conserves queue entries and reduces pressure on RCU and scheduling resources. AMD did not disclose how the FPU was restructured. Die shots suggest two execution blocks splitting the PRF and FP ALUs, one operating on the lower 128 bits of a YMM register, executing x87, MMX, SSE, and AVX instructions, the other on the upper 128 bits for AVX-256 instructions. This improvement doubles the peak throughput of AVX-256 instructions to four per cycle, or in other words, up to 32 FLOPs/cycle in single precision or up to 16 FLOPs/cycle in double precision. Another improvement reduces the latency of double-precision vector multiplications from 4 to 3 cycles, equal to the latency of single-precision multiplications. The latency of fused multiply-add (FMA) instructions remains 5 cycles.

The rename unit receives up to four macro-ops per cycle from dispatch. It maps x87, MMX, SSE, and AVX architectural registers and temporary registers used by microcoded instructions to physical registers. MMX and x87 registers occupy the lowest 64 or 80 bits of a PR. The Zen/Zen+ rename unit allocates two 128-bit PRs for each YMM register. Only one PR is needed for SSE and AVX-128 instructions, the upper half of the destination YMM register in another PR remains unchanged or is zeroed, respectively, which consumes no execution resources. (SSE instructions behave this way for compatibility with legacy software which is unaware of, and does not preserve, the upper half of YMM registers through library calls or interrupts.) Zen 2 allocates a single 256-bit PR and tracks in the register allocation table (RAT) if the upper half of the YMM register was zeroed. This necessitates register merging when SSE and AVX instructions are mixed and the upper half of the YMM register contains non-zero data. To avoid this the AVX ISA exposes an SSE mode where the FPU maintains the upper half of YMM registers separately. Zen 2 handles transitions between the SSE and AVX mode by microcode which takes approximately 100 cycles in either direction. Zeroing the upper half of all YMM registers with the VZEROUPPER or VZEROALL instruction before executing SSE instructions prevents the transition.

Zen 2 inherits the move elimination and XMM register merge optimizations from its predecessors. Register to register moves are performed by renaming the source register and do not occupy any scheduling or execution resources. XMM register merging occurs when SSE instructions such as SQRTSS leave the upper 64 or 96 bits of the destination register unchanged, causing a dependency on previous instructions writing to this register. AMD family 15h and later processors can eliminate this dependency in a sequence of scalar FP instructions by recording in the RAT if those bits were zeroed. By setting a Z-bit in the RAT the rename unit also tracks if an architectural register was completely zeroed. All-zero registers are not mapped, the zero data bits are injected at the bypass network which conserves power and PRF entries, and allows for more instructions in flight. Earlier AMD microarchitectures, apparently including Zen/Zen+, recognize zeroing idioms such as XORPS combining a register with itself and eliminate the dependency on the source register. AMD did not disclose if or how this is implemented in Zen 2. Family 16h processors recognize zeroing idioms in the instruction decode unit and set the Z-bit on the destination register in the floating point rename unit, completing the operation without consuming scheduling or execution resources.

As in the Zen/Zen+ microarchitecture the 64-entry non-scheduling queue decouples dispatch and the FP scheduler. This allows dispatch to send operations to the integer side, in particular to expedite floating point loads and store address calculations, while the FP scheduler, whose capacity cannot be arbitrarily increased for complexity reasons, is busy with higher latency FP operations. The 36-entry out-of-order scheduler issues up to four micro-ops per cycle to the execution pipelines. A 160-entry physical register file holds the speculative and committed contents of architectural and temporary registers. The PRF has 8 read ports and 4 write ports for ALU results, each 256 bits wide in Zen 2, and two additional write ports supporting up to two 256-bit load operations per cycle, up from two 128-bit loads in Zen. The FPU is capable of superforwarding load data to dependent instructions through the bypass network, obviating a write and read of the PRF. The bypass network enables back-to-back execution of dependent instructions by forwarding results from the FP ALUs to the previous pipeline stage.

The floating point pipelines are asymmetric, each supporting a different set of operations, and the ALUs are grouped in domains, to conserve die space and reduce signal path lengths which permits higher clock frequencies. The number of execution resources available reflects the density of different instruction types in x86 code. Each pipe receives two operands from the PRF or bypass network. Pipe 0 and 1 support FMA instructions which take three operands; The third operand is obtained by borrowing a PRF read port from pipe 3, stalling this pipe for one cycle, unless the operand is available on the bypass network. All pipes can perform logical operations. Other operations are supported by one, two, or three pipes. The execution domains distinguish vector integer operations, floating point operations, and store operations. Instructions consuming data produced in another domain incur a one cycle penalty. Only pipe 2 executes floating point store-data micro-ops, sending data to the store queue at a rate of up to one 256-bit store per cycle, up from one 128-bit store in Zen. It also takes care of transfers between integer and FP registers on dedicated data busses.

Same as Zen/Zen+ the Zen 2 FPU handles denormal floating-point values natively, this can still incur a small penalty in some instances (MUL/DIV/SQRT).

Load-Store Unit

The load-store unit handles memory reads and writes. The width of data paths and buffers doubled from 128 bits in the Zen/Zen+ microarchitecture to 256 bits.

The LS unit contains a 44-entry load queue (LDQ) which receives load operations from dispatch through either of the two load AGUs in the EX unit and the linear address of the load computed there. A load op stays in the LDQ until the load completes or a fault occurs. Adding the AGQ depth of 28 entries, dispatch can issue up to 72 load operations at a time. A 48-entry store queue (STQ), up from 44 entries in Zen, receives store operations from dispatch, a linear address computed by any of the three AGUs, and store data from the integer or floating point execution units. A store op likewise stays in the STQ until the store is committed or a fault occurs. Loads and stores are speculative due to branch prediction.

Three largely independent pipelines can execute up to two 256-bit load operations and one 256-bit store per cycle. The load pipes translate linear to physical addresses in parallel with L1 data cache accesses. The LS unit can perform loads and stores out of order. It supports loads bypassing older loads and loads bypassing older non-conflicting stores, observing architectural load and store ordering rules. Store-to-load forwarding is supported when an older store containing all of the load's bytes, with no particular alignment since the Piledriver microarchitecture, is in the STQ and store data has been produced. Memory dependence prediction, to speculatively reorder loads and stores before the physical address has been determined, was introduced by AMD in the Bulldozer microarchitecture.

A two-level translation lookaside buffer (TLB) assists load and store address translation. The fully-associative L1 data TLB contains 64 entries and holds 4-Kbyte, 2-Mbyte, and 1-Gbyte page table entries. The L2 data TLB is a unified 12-way set-associative cache with 2048 entries, up from 1536 entries in Zen, holding 4-Kbyte and 2-Mbyte page table entries, as well as page directory entries (PDEs) to speed up DTLB and ITLB table walks. 1-Gbyte pages are smashed into 2-Mbyte entries but installed as 1-Gbyte entries when reloaded into the L1 TLB.

Two hardware page table walkers handle L2 TLB misses, presumably one serving the DTLB, another the ITLB. In addition to the PDE entries, the table walkers include a 64-entry page directory cache which holds page-map-level-4 and page-directory-pointer entries speeding up DTLB and ITLB walks. The Zen/Zen+ microarchitecture supports page table entry (PTE) coalescing; this feature is probably also present in Zen 2. When the table walker loads a PTE, which occupies 8 bytes in the x86-64 architecture, from memory it also examines the seven other PTEs in the same 64-byte cache line. If they assign a contiguous 32 KiB block of physical pages with the same attributes to the 8 virtual pages, they are coalesced into a single TLB entry greatly improving the efficiency of this cache.

The LS unit relies on a 32 KiB, 8-way set associative, write-back, ECC-protected L1 data cache (DC). It supports two loads, if they access different DC banks, and one store per cycle, each up to 256 bits wide. The line width is 64 bytes, however cache stores are aligned to a 32-byte boundary. Loads spanning a 64-byte boundary and stores spanning a 32-byte boundary incur a penalty of one cycle. In the Zen/Zen+ microarchitecture 256-bit vectors are loaded and stored as two 128-bit halves; the load and store boundaries are 32 and 16 bytes respectively. Zen 2 can load and store 256-bit vectors in a single operation, but stores must be 32-byte aligned now to avoid the penalty. As in Zen aligned and unaligned load and store instructions (for example MOVUPS/MOVAPS) provide identical performance.

The DC load-to-use latency is 4 cycles to the integer unit, 7 cycles to the FPU. The AGUs and LS unit are optimized for simple address generation modes: Base + displacement, base + index, and displacement-only. More complex modes and/or a non-zero segment base increase the latency by one cycle.

The L1 DC tags contain a linear-address-based microtag which allows loads to predict the way holding the requested data before the physical address has been determined, reducing power consumption and bank conflicts. A hardware prefetcher brings data into the L1 DC to reduce misses. The LS unit can track up to 22 in-flight cache misses, these are recorded in the miss address buffer (MAB).

The LS unit supports memory type range register (MTRR) and the page attribute table (PAT) extensions. Write-combining, if enabled for a memory range, merges multiple stores targeting locations within the address range of a write buffer to reduce memory bus utilization. Write-combining is also used for non-temporal store instructions such as MOVNTI. The LS unit can gather writes from 8 different 64-byte cache lines.

Each core benefits from a private 512 KiB, 8-way set associative, write-back, ECC-protected L2 cache. The line width is 64 bytes. The data path between the L1 data or instruction cache and the L2 cache is 32 bytes wide. The L2 cache has a variable load-to-use latency of no less than 12 cycles.

Rome

Rome is codename for AMD's server chip based on the Zen 2 core. Like prior generation (Naples), Rome utilizes a chiplet multi-chip package design. Each chip comprises of nine dies - one centralized I/O die and eight compute dies. The compute dies are fabricated on TSMC's 7 nm process in order to take advantage of the lower power and higher density. On the other hand, the I/O makes use of GlobalFoundries mature 14 nm process.

The centralized I/O die incorporates eight Infinity Fabric links, 128 PCIe Gen 4 lanes, and eight DDR4 memory channels. The full capabilities of the I/O have not been disclosed yet. Attached to the I/O die are eight compute dies - each with eight Zen 2 core - for a total of 64 cores and 128 threads per chip.
