A highly simplified illustration of the Zen microarchitecture a core has a total of 5. Ki. B of L2 cache. Zen is the codename for a computer processor microarchitecture from AMD, and was first used with their Ryzen series of CPUs in February 2. The first Zen based preview system was demonstrated at E3 2.

Overview. The purpose of overclocking is to gain additional performance from a given component by increasing its operating speed. Normally, on modern systems, the. New OC Software and free 3DMark06 and PCMark05 license keys We have updated the overclocking software page on OCinside. This is a technical support forum for resolving all manner of computer issues. Amd Athlon Xp Overclocking Software Cpu OverclockingThe first Zen based CPUs codenamed Summit Ridge reached the market in early March 2. Zen derived Epyc server processors launched in June 2. Zen based APUs are expected to follow in the second half of 2. Zen is a clean sheet design that differs from the long standing Bulldozer architecture. Zen based processors use a 1. Fin. FET process, are reportedly more energy efficient, and can execute significantly more instructions per cycle. SMT has been introduced, allowing each core to run 2 threads. The cache system has also been redesigned, making the L1 cache write back. Zen processors use three different sockets desktop and mobile Ryzen chips use the AM4 socket, bringing DDR4 support the high end desktop Zen based Threadripper chips support quad channel DDR4 RAM and offer 6. PCIe 3. 0 lanes vs 2. TR4 socket 1. 21. Epyc server processors offer 1. PCI 3. 0 lanes and octal channel DDR4 using the SP3 socket. Zen is based on a So. C design. 1. 4 The memory, PCIe, SATA, and USB controllers are incorporated into the same chip as the processor cores. This has advantages in bandwidth and power, at the expense of chip complexity and die area. Zen is the codename for a computer processor microarchitecture from AMD, and was first used with their Ryzen series of CPUs in February 2017. The first Zen based. Benchmark chart of overclocked Intel and AMD CPUs. Made using thousands of benchmark results and updated daily. We take a look through AMDs history in the CPU market. AMD Zen RYZEN CPUs Detailed 8 Cores, 3. Ghz Auto Overclocking With XFR. This So. C design will allow the Zen microarchitecture to scale from laptops and small form factor mini PCs to high end desktops and servers. According to AMD, the main focus of Zen is on increasing per core performance. New or improved features include1. L1 cache has been changed from write through to write back, allowing for lower latency and higher bandwidth. SMT simultaneous multithreading architecture allows for 2 threads per core, a departure from the CMT clustered multi thread design used in the previous Bulldozer architecture. This is a feature previously offered in some IBM, Intel and Oracle processors. A fundamental building block for all Zen based CPUs is the Core Complex CCX consisting of four cores and their associated caches. Processor with more than four cores consist of multiple CCXs connected by Infinity Fabric. Four ALUs, two AGUsload store units, and two floating point units per core. Newly introduced large micro operation cache. Each SMT core can dispatch up to 6 micro ops per cycle a combination of 6 integer micro ops and 4 floating point micro ops per cycle2. Close to 2 faster L1 and L2 bandwidth, total L3 cache bandwidth up 5Clock gating. Larger retire, load, and store queues. Improved branch prediction using a hashed perceptron system with Indirect Target Array similar to the Bobcat microarchitecture,2. AMD engineer Mike Clark2. Branch predictor that is decoupled from the fetch stage. Dedicated stack engine for modifying the stack pointer, similar to Intel Haswell and Broadwell processors2. Move elimination, a method that reduces physical data movement to reduce power consumption. RDSEED support, a high performance hardware random number generator instructions introduced in Intels Broadwell microarchitecture2. Support for SMAP, SMEP, XSAVECXSAVESXRSTORS, XSAVES, CLFLUSHOPT, CLZERO and ADCX instructions. AVX2 support. ADX support. SHA support. PTE page table entry coalescing, which combines 4 ki. B page tables into 3. B page size. Pure Power3. Smart Prefetch. Precision Boost. Extended Frequency Range XFR, an automated overclocking feature which boosts clock speeds beyond the advertised turbo frequency. This is the first time in a very long time that we engineers have been given the total freedom to build a processor from scratch and do the best we can do. It is a multi year project with a really large team. Its like a marathon effort with some sprints in the middle. The team is working very hard, but they can see the finish line. I guarantee that it will deliver a huge improvement in performance and power consumption over the previous generation. Suzanne Plummer, Zen team leader, on September 1. The Zen architecture is built on a 1. Fin. FET process subcontracted to Global. Foundries,3. 3 giving greater efficiency than the 3. AMD FX CPUs and AMD APUs, respectively. The Summit Ridge Zen family of CPUs use the AM4 socket and feature DDR4 support and a 9. W TDP thermal design power. While newer roadmaps dont confirm the TDP for desktop products, they suggest a range for low power mobile products with up to two Zen cores from 5 to 1. W and 1. 5 to 3. 5 W for performance oriented mobile products with up to four Zen cores. Each Zen core can decode four instructions per clock cycle and includes a micro op cache which feeds two schedulers, one each for the integer and floating point segments. Each core has two address generation units, four integer units, and four floating point units. Two of the floating point units are adders, and two are multipliers. There are also improvements in the branch predictor. The L1 cache size is 6. Ki. B for instructions per core and 3. Ki. B for data per core. The L2 cache size 5. Ki. B per core, and the L3 is 1 2 MB per core. Power Iso 4 0 3 Serial Packed 12150 on this page. L3 caches offer 5x the bandwidth of previous AMD designs. History and developmenteditAMD began planning the Zen microarchitecture shortly after re hiring Jim Keller in August 2. AMD formally revealed Zen in 2. AMDs Zen announcement slide. The team in charge of Zen was led by Keller who left in September 2. AMD Senior Fellow and Chief Architect Michael Clark. Zen was originally planned for 2. ARM6. 4 based K1. AMDs 2. 01. 5 Financial Analyst Day it was revealed that K1. Zen design, to allow it to enter the market within the 2. Zen based processors expected for October 2. In November 2. 01. AMD reported that Zen microprocessors had been tested and met all expectations with no significant bottlenecks found. In December 2. 01. Samsung may be contracted as a fabricator for AMDs 1. Fin. FET processors, including both Zen and AMDs then upcoming Polaris GPU architecture. This was clarified by AMDs July 2. Samsungs 1. 4 nm Fin. FET process. 4. 6 AMD stated Samsung would be used if needed, arguing this would reduce risk for AMD by decreasing dependence on any one foundry. Advantages over predecessorseditZens from scratch design is notably different from its predecessors, with many different types of changes and enhancements being made across the board in hopes of making Zen more competitive with Intels architectures, and the software most often built with Intels processor features in mind. Manufacturing processeditProcessors built using Zen utilize 1. Fin. FET silicon. These processors are being produced at Global. Foundries,4. 8 though reports state some Zen processors may also be produced at TSMC. Prior to Zen, AMDs smallest process size was 2. Steamroller and Excavator microarchitectures. The immediate competition, Intels Skylake and Kaby Lake microarchitecture, are also fabricated on 1. Fin. FET 5. 2 though Intel is planning to begin the release of 1. In comparison to Intels 1. Fin. FET, AMD claimed in February 2. Zen cores would be 1. AMD also announced it would be using metal insulator metal process to increase the clock speeds and reduce voltages of its Zen products. For identical designs, these die shrinks would use less current and power at the same frequency or voltage. As CPUs are usually power limited typically up to 1. W, or 4. 5 W for mobile, smaller transistors allow for either lower power at the same frequency, or higher frequency at the same power. PerformanceeditOne of Zens major goals is to focus on performance per core, and it is targeting a 4. IPC over its predecessor. Excavator, in comparison, offered 41.
