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.

    That would be a fantastic "upgrade your OEM tower" card as well, and they could squeeze it into a thunderbolt TDP for a self contained eGPU.

    Assuming the card takes all its power thru the 12V rail in the PCIe slot, wouldn't that then be 66W max?

    From Wikipedia:
    > A full-sized x16 graphics card may draw up to 5.5 A at +12 V (66 W) and 75 W combined after initialization and software configuration as a "high power device".

    At most the auxiliary rails would be used for the fan, or RGB lighting.

    "With a CU count of 40, resulting in 2540 stream processors"
    2560 because 40x64.

    Really cool product and definitely for me, but if you need best laptop that money can buy with ios... go for this!
    It is expensive as a hell, but it is Apple and its is HBM memory, neither known for cheap price! So for that it is not bad at all! If you have money and need, you most probably can not find better laptop!

    1035mhz boost? This is GTX1650/1660 class performance at that frequency, so no wonder it has 50W TDP. Reply

    Look at the TFLOPS. It's 5.3 vs 4.55 for a 2060 Max-Q which is 80W TDP so 15% more performance for 60% less power. Reply

    And it's Navi, so we know those TFLOPS actually mean something.

    I've been yelling at people for ages now that Navi's more than just competitive with Turing at low clock speeds. Will be interesting to see if the benchmarks prove me right!

    Nvidia have a great design that stays efficient right up to the high-end, but the Max-Q performance and heat issues show how difficult it is for them to scale all the way to the bottom range of TDPs on 12nm.

    wide and slow, keeps the power low Reply

    Other World Computing has an eGPU box/5700XT bundle for $750. Obviously, that isn't very mobile but if you don't absolutely need all that GPU power on the road, the eGPU w/5700XT seems like it would be a better solution. Reply
