AMD's Mobile Pro Phoenix Zen 4 Processor with RX 570-Level Graphics Performance

A recent Twitter post from @BenchLeaks revealed another upcoming AMD mobile processor Phoenix on Geekbench browser. This time it's a professional variant of Ryzen mobile chips' 7040 Phoenix class: the Ryzen 7 Pro 7840HS, which has eight cores and a boost clock of 5 GHz. The Geekbench 5 results show impressive performance of the chip's integrated Radeon 780M graphics engine, with computing performance comparable to mid-range desktop GPU hardware from several years ago.

The Geekbench 5 listing shows a benchmark score of 34,490 for the Ryzen 7 Pro 7840HS and its associated Radeon 780M iGP. This level of performance places the 780M at the same level as the desktop Radeon RX 480/RX 570 from a few years ago. For example, the RX 570 scored 34,460 points in OpenCL, 40 points less than the new Ryzen chip.

This is impressive performance for an integrated graphics processor. Of course, this comes from Geekbench and OpenCL tests, which may or may not correlate with actual gaming performance. If the 780M can deliver the same level of performance in games, it will essentially compete with entry-level GPUs like the mobile GTX 1650 Ti (at its lowest power consumption level). But, as always, take these results with a grain of salt. For more details, check out our previous coverage on the Radeon 780M, including its alleged performance gains over the Radeon 680M.

The complete Geekbench specifications show us that the Ryzen 7 Pro 7840HS is housed in an HP ZBook Firefly 14' G10 Mobile Workstation laptop. The chip itself features eight cores, 16 threads, a base clock of 3.8 GHz, and a boost clock of around 5 GHz. Cache capabilities include 32 KB of L1 cache, 1 MB of L2 cache, and an unknown amount of L3 cache. Memory sits at 15.28 GB for this particular laptop model.

For some reason, the Geekbench 5 results show incorrect specifications for the chip's integrated Radeon 780M RDNA 3 graphics processor, which shows only 6 CUs and a disappointing clock speed of 800 MHz for the GPU. In fact, AMD claims that the 780M will come with 12 CUs (768 SPs) and a significantly higher (maximum) clock speed of up to 3 GHz.

While that may not seem like much graphics power, bear in mind that the RX 570 we compared it to uses an older graphics architecture. It may have 2048 shading cores, but they only run at 1.2 GHz, and each one is significantly less powerful than the RDNA 3 shaders in the 780M. We're also seeing a chip that uses a maximum of 54 W of power for the whole package, while the 570 had a nominal power draw of 150 W for graphics alone. The previous generation 680M for comparison scores around 2400 in 3DMark Time Spy graphics, while the RX 570 scores around 4000. Overall, in terms of gaming performance, the 780M probably won't match the RX 570, but it's likely to come close.

The Geekbench report only shows the performance of the integrated graphics and does not disclose the performance of one or several cores of the chip's eight Zen 4 processor cores. But we can expect the chip to be very fast and efficient thanks to the Zen 4 architecture.

The Ryzen 7040 processors (codenamed Phoenix) class is one of AMD's new high-performance processor designs for ultra-thin and ultra-light laptops. The series is the most advanced design in AMD's mobile Ryzen 7000 portfolio, with the latest 4nm node from TSMC, RDNA 3 graphics, and AMD's XDNA AI engine, none of which are present in any other Ryzen 7000 mobile processor design (including 4075 Dragon Range, 7035 Rembrandt-R, etc.).

This new Ryzen 7 7840HS Pro is the first AMD Phoenix-class chip we've seen with the Pro moniker attached. This adds AMD's Pro technologies suite to the processor, which includes 18 months of software stability, 24 months of planned availability, and enterprise-level quality assurance warranty, along with additional security technologies. It's essentially AMD's counterpart to Intel's vPro technology.

The latest reports suggest that the Ryzen 7040 chips will arrive later this month.
