Pro Phoenix Zen 4 Mobile CPU Spotted With RX 570-Level Graphics Performance
New Twitter post by @BenchLeaks has revealed another upcoming AMD Phoenix mobile CPU in the Geekbench browser. This time it’s the Ryzen 7 Pro 7840HS, the professional variant of the 7040 Phoenix class of Ryzen mobile chips, featuring eight cores and a boost clock of 5 GHz. The Geekbench 5 results show particularly impressive performance from the chip’s integrated Radeon 780M graphics engine, with computing performance comparable to mid-range desktop GPU hardware from a few years ago.
A Geekbench 5 listing shows an OpenCL benchmark score of 34,490 for the Ryzen 7 Pro 7840HS and its associated Radeon 780M iGP. This level of performance puts the 780M in the same ballpark as the desktop Radeon RX 480/RX 570 from a few years ago. For example, the RX 570 scored 34,460 points in OpenCL. That’s 40 points worse than the newer Ryzen chips.
That’s impressive performance from an integrated graphics processor. Of course, this is from Geekbench and OpenCL testing and may or may not correlate with real-world game performance. If the 780M can deliver the same performance in games, it will basically compete with entry-level GPUs like the GTX 1650 Ti mobile (at the lowest power consumption level). But as always, don’t take these results for granted. For more details, check out our previous coverage of the Radeon 780M, including rumors that it will perform better than the Radeon 680M.
Geekbench’s full specs show the Ryzen 7 Pro 7840HS housed inside the HP ZBook Firefly 14′ G10 Mobile Workstation Laptop. The chip itself features 8 cores, 16 threads, a base clock of 3.8 GHz and a boost clock of around 5 GHz. Cache capacity includes 32KB of L1 cache, 1MB of L2 cache, and an unknown amount of L3 cache. This particular laptop model has 15.28 GB of memory.

For some reason, the Geekbench 5 results show incorrect specs for the chip’s integrated Radeon 780M RDNA 3 graphics processor. The GPU has only 6 CUs and shows a staggering 800 MHz clock speed. In fact, AMD says the 780M will come with 12CUs (768 SPs) and feature significantly higher (maximum) clock speeds of up to 3 GHz.
That may not sound like a lot of graphics horsepower, but keep in mind that the RX 570 we compared uses an older graphics architecture, with 2048 shader cores. It’s possible, but it only runs up to 1.2 GHz and isn’t significantly more powerful than the 780M RDNA 3 shaders each. We’re also looking at a chip that uses up to 54W of power across the package, while the 570 was rated at 150W for graphics only. The RX 570 gets around 4,000, while the previous-gen 680M compares around 2,400 in 3DMark Time Spy graphics. The 780M probably won’t be able to keep up with the RX 570 in general gaming performance, but it will likely come close.
The Geekbench report only shows integrated graphics performance, not revealing single-core or multi-core performance from the chip’s eight Zen 4 CPU cores. But thanks to the Zen 4 architecture, we can expect the chip to be very fast and efficient.
The Ryzen 7040 class CPU (codenamed Phoenix) is one of AMD’s new high-performance CPU designs for ultra-thin and ultra-light laptops. The series is the most advanced design in AMD’s Ryzen 7000 mobile portfolio, featuring TSMC’s latest 4nm node, RDNA 3 graphics, and AMD’s XDNA AI engine, making it the best choice for other Ryzen 7000 mobile CPUs. Not present in design (including 4075 Dragon Range, 7035). Rembrandt-R, etc.).
This new Ryzen 7 7840HS Pro is the first chip in AMD’s Phoenix class to bear the Pro moniker. This adds AMD’s line of Pro technologies to the CPU. This includes 18 months of software stability, 24 months of planned availability, enterprise-level quality assurance, and additional security technologies. This is essentially AMD’s counterpart to Intel’s vPro technology.
The latest reports suggest that the Ryzen 7040 chip will arrive later this month.
