With the official launch of amd Ryzen 4000 “Renoir” desktop APU, fans are also looking forward to the consumer platform. However, according to Igor’s Lab’s latest revelations, Renoir’s mobile APU or only the bandwidth provided by PCIe 3.0 x8 means that the Nvid RTX 2060 Super and above will experience a performance bottleneck. Given the consistenthigh explosive accuracy of Igor’s Lab, Renoir moves the SoC design of the APU or cuts it again on top of the desktop platform.
If AMD is confirmed to have taken this action, it would mean that the company will cede the high-end mobile market to the Intel TGL gaming notebook competition.
Even if reducing the SoC specification helps reduce power consumption on the mobile platform, the system faces a performance bottleneck caused by the PCIe 3.0 x8 channel when paired with the NViD RTX 2060 Super and above for mid- to high-end gaming graphics.
At the same time, the Big Navi unique in AMD planning will be the first to do this. Intel Tiger Lake not only provides at least PCIe 3.0 x16 channels for stand-up, but even some channels for PCIe 4.0.
Fortunately, this restriction will also appear on the SoC of The Renoir desktop APU (using the AM4 interface) previously exposed by Robert Hallock, which still has access to the PCIe 3.0 x16 channel.
From the SoC structure diagram shared by Igor’s Lab, Renoir Mobile APU provides support for GDDR6 memory and dedicated NVMe SSD channels, meaning that the latter will not be able to cut the PCIe 3.0 channel in half due to preemption of the channel.
In addition, Renoir Mobile APU Restore supports USB 3.0 Gen 2, complemented by a dual-channel DRAM controller. In these respects, AMD has clearly focused on the mainstream market to deliver on its long-standing commitment to reducing the cost of playing for ordinary players.
If you’re sure you don’t have a plan to buy a more powerful GPU than the RTX 2060S, the Renoir Mobile APU still offers an excellent price/performance ratio. But consumers looking for more enjoyment should also consider the Intel TGL game notebook competition.
