AMD has introduced the Radeon Pro 5600M GPU for the Apple MacBook Pro 16-inch. The Radeon Pro 5600M is a Navi 12 GPU with 40 CUs, 2,560 SPs, and features a multi-chip design with 8 GB HBM2 memory. MacBook Pro 16 configurations with the Radeon Pro 5600M will have a US$700 upcharge.

Prospective Apple MacBook Pro 16-inch buyers now have a more powerful GPU option to choose from. AMD has introduced the Navi 12-based Radeon Pro 5600M with 8 GB HBM2 video memory that should offer quite a significant performance uplift from the Navi 14-based Radeon Pro 5500M, which is part of the standard MacBook Pro configuration. 

The AMD Radeon Pro 5600M looks to be a super-binned Apple-exclusive GPU for now. It is being fabbed on the TSMC 7nm process in a multi-chip module design with the GPU die in the center flanked by a 16-bit 4 GB HBM2 VRAM chip on either side. According to AMD, the Radeon Pro 5600M has a boost clock of 1,035 MHz and features 40 Compute Units (CUs), 2,560 Stream Processors (SPs), 2,048-bit 8 GB HBM2 VRAM with 394 GB/s bandwidth, and can deliver up to 5.3 TFLOPs of FP32 performance. 

The use of HBM2 memory is the biggest surprise with the 5600M. In terms of CU and SP count, the Radeon Pro 5600M is similar to the desktop Radeon RX 5700 XT. However, the latter is clocked higher (1,905 MHz) and has a higher memory bandwidth (448 GB/s) that enables the 5700 XT to offer up to 9.8 TFLOPs of peak FP32 performance.

All this power is offered in a 50 W total graphics power (TGP) envelope — same as that of the Radeon Pro 5500M and the Radeon Pro 5300M. This makes the Radeon Pro 5600M an incredibly powerful GPU option for the Apple MacBook Pro 16-inch. 

For perspective, the AMD Radeon RX 5600M found in the Dell G5 15 SE 5505 is a Navi 10 part with just 36 CUs, 2,304 SPs, and a 192-bit 6 GB GDDR6 VRAM in a 60 W TGP.

Buyers can now configure the MacBook Pro 16-inch with the Radeon Pro 5600M for a US$700 mark-up. It is not cheap, but those who may need such raw GPU power to accelerate their workflows may find benefit. The standard Radeon Pro 5300M and Radeon Pro 5500M with 4 GB and 8 GB GDDR6 options continue to be available as well.

It remains to be seen how would the real-world performance of the Radeon Pro 5600M be under load given the chassis and thermal constraints. There is a possibility that AMD may have other Apple-exclusive GPUs with HBM2 memory for the iMac refreshes that are likely to be announced at WWDC 2020

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
