AMD Phoenix mobile Zen 4 CPU

Updated: Nov 19



The new AMD Phoenix APU will offer a lower number of CPU cores compared to Dragon (Phoenix with up to 8 cores, Dragon with up to 16 cores) and Phoenix will be a great balance of GPU and CPU performance.


AMD's new Phoenix chips will have an integrated RDNA 3 GPU with up to 12 CUs (Compute Units) and 6 WGPs (Work Group Processors).


We're told to expect 2.6GHz to 3GHz for the integrated GPU clock speeds, while CPU and GPU core counts on the new RDNA 3-based Phoenix are identical to the RDNA 2-based Rembrandt APU.


RDNA 3 has architecture changes and more underneath, so performance boosts will be interesting to see when AMD Phoenix-powered gaming laptops arrive later this year (2022).


As for the Zen 4-powered mobile CPU offerings, there will be the Ryzen 9 7980HS with 8 cores (12 CUs + 6 WGPs) and the Ryzen 9 7900HS with 8 cores (12 CUs and 6 WGPs) but we should expect some CPU clocks + TDP tweaks between these two new AMD Phoenix chips.


There's also the Ryzen 7 7800HS with 8 cores (12 CUs and 6 WGPs) as well as the Ryzen 5 7600HS with 6 cores (6 CUs and 3 WGPs).


We're told that the target for the highest end of the AMD Phoenix-based gaming laptops will be "about" the GeForce RTX 3060 mobile, but Red Gaming Tech also notes that the gaming and TFLOPs performance is for the higher TDP configurations (60W to 70W).


Lower TDP variants of the AMD Phoenix processors will be available, with 35W models that will still perform excellently per Red Gaming Tech.


We will also get next-gen PCIe 5.0 support of course, which won't help out in the GPU department a whole bunch, but for super-fast storage... it'll make for an awesome content-creating machine on the go.


PCIe 5.0 enabled storage, with up to 8 cores of Zen 4 processing power with an integrated RDNA 3 GPU?


Mmm, Not bad, AMD!

We're also told we will have DDR5 and LPDDR5 support which has been "confirmed" by multiple sources at Red Gaming Tech, with a single source saying AMD Phoenix has LPDDR5X support, too, at up to LPDDR5X-8400!


Yummmmm!


On the higher-end side the AMD Phoenix processors, we have the Ryzen 9 7980HX with 16 cores, the Ryzen 9 7900HX with 12 cores, the Ryzen 7 7800HX with 8 cores, and finally, the Ryzen 5 7600HX with 6 cores.


AMD Ryzen Zen4 Mobile Processor Naming Scheme Explained


The AMD Ryzen 5 7640U is an upcoming processor meant for premium ultrathin laptops.


All the Ryzen mobile processors launching in 2023 will begin with the number 7, while the processors launching in 2024 and 2025 will be denoted by 8 and 9.


As per the official instructions, the Ryzen 5 7640U will be launched in 2023 and it will be a Ryzen 5 series processor based on the Zen 4 architecture.


It will be a lower model within the segment, and the processor will have a TDP of 15-28W and will be meant for the premium ultrathin laptop market segment. Within the Ryzen 7000 series mobile processors, the company will have various models, and here are the details regarding the same.


The Ryzen 9 and the Ryzen 7 series of processors will consist of sub-series like the 7045 (Dragon Range) meant for extreme gaming and creators. Similarly, the 7040 (Phoenix) is targeted for the elite ultra-thin laptops market.


The Ryzen 7035 (Rembrandt-R) will be found on premium, thin, and light laptops, while the Ryzen 7030 (Barcelo-R) processors will be meant for mainstream thin and light laptops.


Lastly, the Ryzen 7020 (Mendocino) processors are meant for everyday computing.

Mega YUMMM!


Over at Ashes of the Singularity ‘leak’ website, we can now find a benchmark result featuring an alleged Ryzen 9 7845HX processor.


The data associated with this SKU is limited, but the software ‘confirms’ it is a 12 core & 24 thread SKU.


The same configuration is used by Ryzen 9 7900X desktop CPU and displayed in the same way (24 physical and logical cores).


What this means is that the 7845HX CPU is likely a repurposed desktop silicon, similar to Intel HX series soon to be upgraded to 13th Gen Core series. Also, the first Ryzen-HX SKU to feature more than 8 cores.



This summer AMD revealed its plan to change the Ryzen 7000 mobile naming schema.


Along the new disclosure, AMD confirmed a Ryzen 9 7945HX CPU “Dragon Range” Zen4 CPU.


One might assume that we will get a 16-core SKU for laptops as well, which would have to compete against Intel Core i9-13900HX with 24 cores (8P+16E).



Should AMD use the same desktop I/O die for its mobile SKUs, then the integrated graphics might be limited to 2 Compute Units.


However, since this is a chiplet design, AMD has a choice to replace the IOD with a more powerful graphics solution.


At the same time, AMD could limit other features that are not as important to the mobile segment as they are for desktop, such as the number of PCIe lanes.


AMD Ryzen 7000HX series are now expected to launch next year, possibly at CES 2023. The HX series represent the highest tier in AMD mobile portfolio, designed for extreme gaming and content creation.


Looks Delishus!
