The Samsung Exynos + AMD Radeon announcement has been pushed out to July, but sources indicate Mali-beating performance.

Samsung Exynos + AMD Radeon reveal pushed back to July, leaks show off Mali-beating performance

But there’s also a lot of throttling.

The AMD-Samsung collaboration to deliver Radeon graphics to a mobile SoC, which has been in the works for two years, is now nearing completion. While Ice Universe, a well-known mobile leaker, reports that the product’s release date has been pushed back to July, speculations imply that it is more than capable of competing with existing and future Mali GPUs.

The ideas for a Samsung SoC with Radeon graphics have been discussed extensively since the original revelation in 2019, but it has resurfaced when AMD CEO Dr. Lisa Su mentioned it during her Computex 2021 presentation.

According to Ice Universe, the Exynos + Radeon collaboration was due for release this month, but it’s been pushed to July. However, samples are already in hand of partners and in the testing phase. If posts on Korean forum Clien are to be believed, the SoC is showing strong results against competitors after having beaten Apple’s A14 Bionic earlier this year.

The OP of the Clien thread says that at peak performance, the mobile RDNA2 GPU narrowly beat out Arm’s next-generation Mali GPU. It apparently suffered greater throttling than predicted after the first round of testing, losing around 20% performance after the first test and then 30% after the second – yet even when throttled thus severely, the mRDNA2 GPU was allegedly still able to outperform the current high end Mali GPU (presumably the Mali-G78, unveiled last year).

According to the forum discussions, the findings are so outstanding that Samsung is abandoning their own GPU development efforts, and Google has been eyeing the partnership and may have joined up as a customer.

 

While these early results look promising, a drop in performance by 30% after just two test runs isn’t great, especially as GPU-demanding loads like games require sustained performance rather than transient loads like many benchmarks. This, unfortunately, seems to be a product of the SoC’s manufacturing process more than the chip’s own design, as previous testing by Anandtech has pointed to Samsung’s 5 nm node still only playing catch-up to TSMC’s 7 nm products in efficiency terms.

However, the Exynos-Radeon partnership has been rumoured to be coming to laptop platforms in favour of Qualcomm’s 8cx Gen 3, which could provide far greater headroom in thermals and power management. This would put the processor against the 8cx’s Adreno graphics, about which Qualcomm has been pretty tight-lipped thus far.
