The AMD Ryzen 9 7845HX (“Dragon Range”), a Zen 4-based APU with 12 cores and a total of 24 threads for mobile use, has now appeared for the first time in the Ashes of the Singularity benchmark database (test ). Therefore, the specified APU with 55 watts (+) is largely based on AMD Ryzen 9 7900X (test).
Dragon Range and Phoenix enter the notebook
The first information about AMD Phoenix and AMD Dragon Range leaked already in May, and it is said that they will bring the new Zen 4 architecture to the manufacturer’s mobile APUs in the TDP range of 35 watts to 45 watts or 55 watts and above.
The AMD Raphael, Dragon Range and Phoenix thus cover the range from 35 watts to 170 watts and all offer support for DDR5 and PCIe 5.0 as well as an integrated graphics unit based on RDNA 3.
- AMD Raphael, Zen 4, DDR5, PCIe 5.0, 65W+
- AMD Dragon Range, Zen 4, DDR5*, PCIe 5.0, 55W+
- AMD Phoenix, Zen 4, DDR5*, PCIe 5.0, 35W+
*) Mobile CPUs/APUs also support LPDDR5
If AMD uses the same I/O matrix for its mobile SKUs, then integrated graphics will likely be limited to just 2 compute units and 128 shader units on desktop, as with the Ryzen 7000 (test).
On this point, the rumors reached the stars from the beginning and spoke of up to 1,536 ALU. As with Intel for years, there could be a dichotomy: High-end laptop solutions, often paired with a dedicated GPU, look more like classic desktop CPUs with rudimentary iGPUs, while smaller variants they are still full APUs.
The HX series based on the Zen 4 architecture is expected to debut at CES 2023, but details on clock rates and iGPU are still scarce. The Twitter user had the input of the Ryzen 9 7845HX @BenchLeaks found.
