AMD Phoenix RDNA3 iGPU may be as fast as slowest GeForce RTX 3060 mobile GPU

AMD Phoenix APU with medium discrete GPU performance

Greymon55 claims that the upcoming integrated graphics into the AMD Phoenix APU can show comparable performance to the most power-constrained version of the RTX 3060 mobile device.

The AMD Ryzen 7000 series will officially include two mobile series: Dragon Range for high-performance laptops and Phoenix for thin and light designs. The latter is now expected to use the RDNA3 graphics architecture combined with Zen4 compute cores.

Phoenix APUs will run in the 35 to 45W range, which could mean the Ryzen 7000HS and 7000H series. However, this capability applies not only to graphics, but also to the Zen4 core and other integrated logic. That said, Greymon claims an RTX 3060M with an integrated RDNA3 GPU alone can deliver 60W (formerly known as Max-Q) performance, which would be big news for “lightweight” gaming.

It’s important to note that the 60W version of the RTX 3060 isn’t very popular in the latest designs, but it can be found in laptops like the 2021 Asus ROG Zephyrus G14, and even there it supports Dynamic Boost (+20W), So on one hand – side-by-side comparisons can be hard. Still, such a power-limited RTX 3060M-class GPU is up to 30% slower than the fully unlocked version. It ships with a GPU clock in the 817-1282 MHz range, which is significantly less than the 115W variant’s fastest 1702 MHz clock.

Meanwhile, the AMD Ryzen integrated RDNA graphics card already comes with a 2.4 GHz clock (Ryzen 9 6900HS). The AMD Phoenix iGPU will use 5 nm process technology and further optimizations, possibly enabling higher iGPU clocks. So the Phoenix RDNA3 iGPUs don’t necessarily have to have as many shaders as the RTX 3060, they just need to be faster.

NVIDIA’s RTX 3060 laptop is aimed at 1080p gaming in “ultra” quality. To be sure, including DLSS support played a role in the popularity of the 3060M, but AMD has since released its FSR super-resolution technology and may soon offer similar performance to laptops that don’t even have discrete GPUs.
