[Solved] AMD Navi 7nm for eGPU - Radeon RX 5700 & RX 5700 XT
@kushnyc Imagine a Radeon card with two Navi dies. AMD has done this fairly often with Radeon Duo series through different GPU families.
@itsage oh I can imagine it - Vega II Duo is around the corner. But my gut says we won’t see Navi Duo for consumers - if ever it won’t be until another process shrink - maybe 4nm? They still have plenty of headroom to scale up a larger die that consumes < 280W and rivals nVidia’s top end.
RX5700xt custom designs are finally coming out, one can find some reviews here:
Also TechpowerUp reported that AMD will still continue to offer its blower solution along the custom gpu solutions.
Closing thought, i was thinking that custom pcb's would bring some overall additional performances to the card, but i was wrong.
It seems, at the end, that AMD already maxed out navi by default, not much overclocking room is left.
It also seems the card will still top out at 2.1ghz +/- even with a decent air cooler, it's the drivers boosting algorithm that impose the gpu speed at then end.
So my take on this is to buy the cheapest custom air cooled solution [After had leveraged couple reviews], i saw the sapphire model selling 20e more than the basic AMD blower model.
If custom models price drop a bit and drivers begin to be efficient in games [Console release matter here], navi will be a fairly competitive mid/high end gpu.
So overclocking is basically not an option it seems? Is that because of the board or the chip or what? Is it still worth getting one of you can’t overclock it?
I would maybe need to rephrase the sentence into: not much overclocking is left for AIB partners to offer better graphic performances.
More or less like Nvidia is already doing with its partners, still Nvidia don't need them to propose a better overall product to the customer, unlike AMD.
The custom Pulse Sapphire is on overall better card for only 20e more with better noise and thermals output, but AMD couldn't bother with its the custom design.
Also one can definitively overclock the gpu if he wish so, one can find the link of the tool to overclock the RX5700 series in the thread.
Under air cooling it will top out to 2.1Ghz +/- as said previously, one can reach 2.2Ghz+ under water.
But i suppose that AMD is already squeezing the max of navi, 7nm don't scale well with voltage so clocks, due to the transistor density and T° hotspots.
So, this will be my choice...2 slot width!
Now we just need macOS drivers and better optimised W10 drivers (for loopback).
2017 13" MacBook Pro Touch Bar
GTX1060 + AKiTiO Thunder3 + Win10
GTX1070 + Sonnet Breakaway Box + Win10
GTX1070 + Razer Core V1 + Win10
Vega 56 + Razer Core V1 + macOS + Win10
Vega 56 + Mantiz Venus + macOS + W10
So, I'm force to buy the more expensive NAVI VII graphic card?
There is no drivers supporting Navi for MacOS, at the moment of writing this post!
Also if you want my bare opinion, don't bet on apple god will to deliver driver for Navi, at the end it's competing with its own supported Vega gpu's!
Apple signed for the Vega architecture, i suppose some 7nm Vega dies have been shipped to apple for single and dual gpu integration.
So Navi drivers are not the main apple issue at the moment, still hope to be proved wrong tho.
Also as @itsage pointed out multiples time, Vega64 is the best price/perf at the moment for MacOS usage.
I would not advice to buy Radeon 7, unless you really need the computation power or have some buck to lend out and like full fan noise when put to sleep.
I hope so, custom version of the card would fit nicely and are powerful enough to be relevant.
We need to wait and see how the RX5700 sell out, if it become profitable manufacturers will think about proposing also an eGPU box.
I would still check reviews and user experience before even thinking buying it.
