First Benchmarks of AMD Ryzen 3 7440U “Phoenix” Quad-Core Zen 4 APU Unveiled, Strong Single-Core Performance

The first benchmarks of AMD's only Zen 4 quad-core, the Ryzen 3 7440U "Phoenix" APU, have appeared on Geekbench.

The AMD Ryzen 7 7440U is the most entry-level Phoenix APU within the Ryzen 7040 stack and is also the only quad-core Zen 4 chip released to date. On the desktop front, the least you can get is six cores and twelve threads so quad-cores are currently only restricted to the mobility lineup but that might change with the upcoming Ryzen 7000G APUs for AM5 desktops which may introduce a quad-core chip for the budget segment.

Anyways, moving on to the specs, the AMD Ryzen 3 7440U "Phoenix" APU features 4 Zen 4 cores, 8 threads, a base clock of 3.0 GHz, and a boost clock of up to 4.7 GHz. The chip has 4 MB of L2 and 8 MB of L3 cache and is rated to operate at 28W (15-30W configurable TDPs). The APU also features a Radeon 740M iGPU based on the RDNA 3 graphics architecture with 4 Compute Units running at a 2.5 GHz clock speed. The CPU also leverages the new Phoenix2 die with a hybrid Zen 4 and Zen 4C configuration.

As for performance, the AMD Ryzen 3 7440U "Phoenix" APU scored 2323 points in single-core and 6571 points in multi-core tests within Geekbench 6. The test setup was a SolidRun Bedrock R7000 Mini PC which comes with a passive-cooled design, support for DDR5 SO-DIMM memory (16 GB in the tests), and a wide range of IO capabilities. The CPU ran at its peak 4.7 GHz clocks across all Zen 4 cores which means that the passive cooled solution did its job well.

Note: All of the chips above feature 4 cores and 8 threads.

You can see in the benchmarks above that the AMD Ryzen 3 7440U "Phoenix" APU sits comfortably ahead of all other quad-core chips in single-threaded benchmarks thanks to Zen 4's IPC uplift and clock speed improvements. Meanwhile, the Intel Raptor Lake and Alder Lake chips do lead in the multi-core segment which happens to do with the higher TDP and cache amounts but the 7440U at 28W is a seriously efficient chip. A desktop Zen 4 Quad-Core APU should end up being the fastest 4-core chip around but it remains to be seen if AMD will offer anything besides 8 core & 6 core APUs for AM5.
