Today AMD has officially announced one of the long rumoured missing Navi parts in the form of the new Radeon Pro 5600M mobile GPU, seeing the Navi 12 design finally take shape as a product.

The new high-end mobile GPU is a successor to the Radeon Pro Vega 20 and Vega 16 designs released back in 2018, products that ended up being used in Apple’s MacBook laptops. The new Radeon Pro 5600M also sees its debut in the new 16” MacBook Pro that’s also been debuted today. Apple has traditionally had exclusive rights to these mobile Radeon Pro SKUs so it’s likely this exclusivity also applies to the new Radeon Pro 5600M.

The new mobile GPU is characterised by its large compute unit count as well as its usage of HBM2 memory. With a CU count of 40, resulting in 2560 stream processors, the Radeon Pro 5600M actually matches AMD’s current best desktop graphics designs such as the Navi 10-based Radeon 5700XT. A key difference here lies in the clocks, as this mobile variant only clocks up to a maximum of 1035MHz, resulting in a theoretical maximum throughput of 5.3TFLOPs, quite a bit less than its desktop counterpart which lands in at 9.75TFLOPs.

In terms of bandwidth however, the mobile chip more than keeps up with its desktop counterpart. AMD is using a 2048-bit HBM2 memory interface to up to 8GB of memory running at 1.54Gbps, resulting in a bandwidth of 394GB/s, only a bit less than the 448GB/s of the Radeon 5700XT.

The Radeon Pro 5600M is advertised with a total graphics power (TGP) of 50W, identical to the TGP of the Radeon Pro 5500M and the Radeon Pro 5300M. Both of those, in turn, are based on the Navi 14 die, which contains far fewer compute units. This makes the Radeon Pro 5600M an incredibly performant and efficient design – albeit one that's undoubtedly expensive to build.

The new Radeon Pro 5600M is now available inside of Apple’s MacBook Pro 16” as an BTO upgrade option, and comes at a $700 mark-up versus the default Radeon Pro 5500M GPU.

    In a 50W TDP? 🤣

    Haters are gonna hate. Don’t like it don’t buy it. Totally cool. But don’t say there’s something better in that power envelope.

    Something like a Ryzen/2060 MaxQ Asus TUF is pretty close... and its $1000.

    Sure, the screen and battery might be worse, but spending that remaining $2k could remedy that.

    "Anyone with a little commonsense will go and buy a much better laptop for that price"

    Just curious: where can "anyone" buy a "better laptop for that price" that runs Max OS X ? (which is the entire reason to buy an apple product - OS X)

    Does it come with insurance for the inevitable tinnitus?

    Remember, folks... thin is in.

    The Radeon Pro 5600M appears to be identical to the RX 5700 XT (memory type aside), so the former should also have 64 ROPs. So 5600M has 46% lower performance at a 78% lower TDP than the 5700 XT. Since 5600M is a laptop GPU the trade-off is fully worth it. Apple should be happy.

    Error in table: the 5500M can have up to 8GB VRAM, not 4GB. Apple has this config available for the MBP 16.

    Hmmmm. The row labelled: 'Memory Clock' has values that are described as 'Mbps' which seems more like Mega bits per second (which is a *bandwidth* rather than a clock speed like MHz). Isn't that odd?
