![]() The physical register file has been upped from 168 to 180 entry (rename space).

The L1 cache is 32K with the 8-way association and L2 cache is still 512K with the 8-way association. In addition to more IPC (Instructions per Core), the new Cores in Zen 2 have improved branch predictor based on TAGE and revised L1 cache structure. The new Zen 2 microarchitecture is based on the 7nm fabrication process. By the way, you will be needing Motherboard For Ryzen 5 3600, but for that, we already have a guide, so check that as well. And today we are going to write on AMD RyReview. There are multiple advancements in Zen 2 over the predecessor. With Zen 2, AMD has furthered the technological advancement and maturity of their highly popular Zen architecture for Ryzen series of CPUs. Last but not the least, this APU is manufactured on a 28 nm process that's really, really old at this point (late 2022), making for very low energy efficiency.“More Cores, More Cache, More Tech” is a tagline when it comes to AMD’s next generation of microarchitecture Zen2 which is based on their altogether new microarchitecture called Zen when launched in 2016 and followed by Zen+. Choosing the lowest value possible will allow for passively cooled designs. Laptop manufacturers are free to change this value to anything between 10 W and 15 W with clock speeds and performance changing accordingly as a result. More details about the GPU are available in the linked articles above. The integrated Radeon R5 (Stoney Ridge) GPU has 192 active shader units (3 compute cores) clocked at up to 900 MHz. Much like with Intel Celerons, expect a system built around an A9-9425 to perform poorly in all but the most basic tasks. The average 9425 in our database proves to be a rather slow CPU, its multi-thread benchmark scores only just matching those of Intel Core i3-4012Y. It also includes a Radeon R5 GPU with 192 shaders at up to 900 MHz as well as a single-channel DDR4-2133 memory controller, H.265 video decoder and chipset with all I/O ports. It integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked at 3.1 GHz to 3.7 GHz. Compared to the one year older A9-9420, the 9425 has a 100 MHz higher CPU clock speed (base and boost) as well as a marginally faster iGPU. The AMD A9-9425 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2018. This means the CPU is a good choice for thin and light notebooks, but also 15-inch devices with better cooling capabilities. More details about the GPU are available in the linked articles above.ĪMD specifies the TDP of the A9-9420 with 15 Watts, but it can be configured between 10-25 Watts. The integrated Radeon R5 (Stoney Ridge) GPU has 192 active shader units (3 compute cores) clocked at up to 800 MHz. The TDP can be configured between 10-25 Watts, so there can be big performance differences under sustained workloads. ![]() The level of performance should be similar to a Core-m3 and therefore also be sufficient for more demanding applications. Compared to older Carrizo-L/Beema quad-cores, the APU should still perform pretty well. The multi-core performance on the other hand is much lower compared to the Bristol Ridge models. Thanks to the high maximum clock of up to 3.6 GHz, the single-core performance should be pretty good. AMD's Bristol Ridge and Stoney Ridge Architecture.More technical details are available in the following articles: Stoney Ridge is the designation for the smaller dual-core and single-core chip, while Bristol Ridge is the bigger quad-core chip with dual-channel memory controller. The memory controller now also supports DDR4-RAM, in this case up to 2133 MHz. ![]() Thanks to optimized manufacturing processes and more aggressive Boost behavior, however, the clocks are a bit higher at the same power consumption. Stoney Ridge is the successor of the Carrizo architecture and the design is almost identical. It also includes a Radeon R5 GPU with 192 shaders at 800 MHz as well as a single-channel DDR4-2133 memory controller, H.265 video engine and chipset with all I/O ports. ![]() It integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 3 - 3.6 GHz. At its launch, the A9-9420 is the fastest Stoney Ridge processor (dual-core version of Bristol Ridge) and takes over that place from the A9-9410 (-100 MHz CPU clock). The AMD A9-9420 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2016. ![]()
