AMD announces its new Zen 3 Ryzen 5000 Mobile ‘Cezanne’ processors for high-end gaming laptops

In the latest CES 2021 Keynote, AMD officially announced its next-generation Zen 3 powered Ryzen 5000U & Ryzen 5000H CPU lineup for the notebook and laptop market segment. Codenamed as ‘Cezanne’, the Ryzen 5000 U & H series processors feature the brand new core architecture and deliver vastly improved efficiency & performance metrics compared to previous gen Ryzen 4000 ‘Renoir’ chips.

The Ryzen 5000H lineup is based on the Zen 3 architecture and aimed at the high-performance gaming segment, while the Ryzen 5000U features both Zen 3 ‘Cezanne’ and Zen 2-based ‘Lucienne’ chips.

AMD says the new chips set the new standard for battery life in x86 notebooks and remain the only 8-core x86 chips for ultrathin laptops. The 13 new processors span from low-power 15W chips up to two new 45W+ HX-series models designed to bring desktop PC-like gaming performance to notebooks. These eight-core HX models carve out a new high-performance niche by bringing CPU, memory, and fabric overclocking to AMD-powered notebooks for the first time.

AMD also expanded its HS series with four flagship chips that slot in with boost clock speeds that stretch up to 4.8 GHz within the 35W TDP envelope. Two new 45W H-series models, which come in both six- and eight-core flavors, are trailed by five U-series processors.

AMD also conducted a demo of its RDNA2 mobile graphics cards that will come to market in the first half of this year. They’ll be accompanied by unspecified new RDNA2 cards for the desktop PC.

As the full press release reads,

Today, AMD (NASDAQ: AMD) announced the full portfolio of AMD Ryzen™ 5000 Series Mobile Processors, bringing the highly-efficient and extremely powerful “Zen 3” core architecture to the laptop market. New AMD Ryzen 5000 Series Mobile Processors provide unprecedented levels of performance and incredible battery life for gamers, creators, and professionals. New laptops powered by Ryzen 5000 Series Mobile processors will be available from major PC manufacturers including ASUS, HP and Lenovo, starting in Q1 2021.

“As the PC becomes an even more essential part of how we work, play and connect, users demand more performance, security and connectivity,” said Saeid Moshkelani, senior vice president and general manager, Client business unit, AMD.

“The new AMD Ryzen 5000 Series Desktop and Mobile Processors bring the best innovation AMD has to offer to consumers and professionals as we continue our commitment to delivering best-in-class experiences with instant responsiveness, incredible battery life and fantastic designs. With our PC partners, we are delivering top-quality performance and no-compromise solutions alongside our record-breaking growth in the notebook and desktop space in the previous year.”

The Ryzen 5000 mobile processors all come with threading enabled, higher boost clocks than the previous-gen, and support CPPC (Collaborative Power and Performance Control) technology. AMD’s top tier mobile parts are all in the H-series.

Traditionally these processors are listed with a TDP of 45 W, however last year we saw AMD experimenting with a newer 35 W category called ‘HS’. This year AMD is again introducing a new level called ‘HX’ for its overclocking models, going above the standard H-series TDP.

AMD Ryzen 5000 Series Mobile Processors:

Building upon the previous generation of leadership mobile processors, the Ryzen 5000 Series includes high-performance H- and ultra-mobile U-Series processors. At the top of the product stack, AMD Ryzen 5000 H-Series Mobile Processors deliver impressive gaming experiences by combining unmatched performance with outstanding battery life, featuring up to 8 cores and 16 threads and built on the new AMD “Zen 3” architecture.

Topping out the mobile processor offering, the HX Series processors provide gamers and creators with elite-level performance while HS processors bring the power of H-Series in thinner and lighter form factors. The new AMD Ryzen 9 5980HX processor is capable of up to 23% increased single-threaded performance and up to 17% faster multi-threaded performance over the previous generation making it the ideal solution for gaming and creator notebooks.

For mainstream consumers looking for performance on-the-go, the AMD Ryzen 5000 U-Series Mobile Processors offer the perfect blend of performance and efficiency. The new AMD Ryzen 7 5800U processor offers:

  • Up to 16% more single-threaded performance and up to 14% faster multithreaded performance over the previous generation
  • Up to an incredible 17.5 hours of general usage battery life and up to 21 hours of movie playback on a single charge

These are the full specs, as summarized by Wccftech.

AMD Ryzen 9 5000H Series APUs:

The AMD Ryzen 9 5980HX and Ryzen 9 5900HX CPUs are going to be the flagship offering within AMD’s Cezanne-H line of notebook chips. The processor will be featuring brand new Zen 3 cores which we have seen on the desktop Ryzen 5000 lineup and as such, we can expect some huge gains in single-thread processor performance.

Specifications wise, the AMD Ryzen 9 5900HX will be offering 8 cores and 16 threads. The chip will feature 16 MB of L3 cache and 4 MB of L2 cache. The base clock for both chips is rated at 3.30 GHz & the boost clocks are rated at 4.60 GHz for the Ryzen 9 5900HX and 4.80 GHz for the Ryzen 9 5980HX. Other features of the chip include an enhanced Vega GPU and also overclocking support which would be a first for AMD on the notebook segment. As such, the HX series processors will come with a higher thermal range and TDPs rated beyond 45W.

There are also the standard AMD Ryzen 9 5900H and Ryzen 9 5900HS CPUs which will feature the same core configuration but run at lower clock speeds of 3.30/4.60 GHz & 3.10 & 3.00/4.60 GHz base & boost frequencies, respectively.

AMD Ryzen 7 5000H Series APUs:

The AMD Ryzen 7 5800H on the other hand is based on the Zen 3 core architecture and as such, it should be part of the Cezanne-H lineup which is the direct replacement to the Renoir-H Ryzen 7 4700H CPU which utilized the Zen 2 core architecture.

Coming to the specifications, the AMD Ryzen 7 5800H features 8 cores and 16 threads. The chip was running at a base clock of 3.20 GHz and a boost clock of 4.40 GHz. All cores were averaging at around 4.40 GHz within the given TDP. The CPU features 16 MB of L3 cache and 4 MB of L2 cache.

The L3 cache is a major upgrade over the Ryzen 4000U and Ryzen 4000H ‘Zen 2’ CPUs, offering increase inter-core latency speeds and bandwidth. The CPU will come with AMD’s enhanced Vega graphics core based on the 7nm process node.

AMD Ryzen 5 5000H Series APUs:

The AMD Ryzen 5 5600H is a 6 core and 12 thread chip that is based on the Zen 3 architecture. It features a base clock of 3.30 GHz and a boost clock of 4.20 GHz. The CPU carries 8 MB of L3 cache and 3 MB of L2 cache.

For graphics, AMD will be relying on its trusty Vega GPU for now with higher clocks than the Ryzen 5 4600H but the same CU count of 6, offering 384 stream processors. The TDP will be set at 35W and will be configurable up to 45W.

AMD Ryzen 7 5000U Series APUs:

The Ryzen 7 5700U also features 8 cores and 16 threads but with 8 MB of L3 cache and lower clock speeds of 1.80 GHz base and 4.30 GHz boost. The Ryzen 7 5700U features an 8 CU Vega iGPU too but clocks in at 1900 MHz.

AMD Ryzen 5 5000U Series APUs:

The Ryzen 5 5600U features 6 cores and 12 threads, and will be based on the Zen 3 core architecture and feature a base clock of 2.30 GHz and a base clock of 4.2 GHz. The chip will also feature an enhanced Vega 7 graphics chip with 7 compute units or 448 stream processors. The GPU will be clocked at 1.8 GHz and the TDP of the chip will be maintained at 10-25W.

Compared to the Ryzen 5 4600U (Renoir-U) APU, the Cezanne-U APU comes with a 200 MHz higher base and boost clocks, 1 more compute unit (+64 cores), and a 300 MHz GPU clock speed bump.

The Ryzen 5 5500U also features 6 cores and 12 threads based on the Zen 2 core architecture. It has clock speeds rated at 2.10 GHz base and 4.00 GHz boost and carries 8 MB of L3 cache which is lower than the 12 MB L3 cache featured on the Cezanne Ryzen 5 part. The iGPU includes a 7 CU (448 SP) Vega chip which is clocked at 1800 MHz.

AMD Ryzen 3 5000U Series APUs:

Finally, there are the Ryzen 3 5400U (Cezanne) and Ryzen 3 5300U (Lucienne) parts which feature 4 cores and 8 threads. The 5400U features an 8 MB L3 cache while the 5300U features a 4 MB L3 cache. The AMD Ryzen 5 5300U is clocked at a 2.60 GHz base and a 3.80 GHz boost clock. Both chips feature a 6 CU (384 SP) Vega iGPU with the former clocked at 1600 Mhz and the latter running at 1500 MHz.
