Hey guys,
As the title describes, I wanna go for Sapphire R9 nitro tri X 4gb hbm one. But will this get drivers update in future?
And will it be as good as RX 480 drivers (latest)? Coz Rx 480 drivers have closed the gap between gtx 1060 since it's launch.
Thank you.

The Ati video driver package supports all manner of Ati gpu chips.

So it is possible for tweaks and upgrades to the driver to get more performance out of any gpu that uses the driver set.

HBM memory may only run at a maximum of 1000 Mhz speeds.
But it is how wide the data bus is in bits that also effect how well a card performs.

A RX card for example may have memory running at 1400 Mhz speed, but the data or bus may only be 256 bits wide of data per clock cycle vs Hbm memory running on a 4096 bit data bus that is, or will be three times more data of information per clock cycle Sia.

It means the RX card would have to perform 3 more clock cycles to reach the same amount, or process the data
taking more time to perform.

So HBM memory is faster in respect.
Than a RX 480 graphics card with a 256 bit memory bus per clock cycle.

It is likely the new RX 490 card will carry HBM II memory.

If Rx 490 comes with HBM II (which I think I is more likely) then the driver updates for it will mean that it is an update for HBM drivers as well?

And how is hbm 3 times faster than Rx? Coz 256 bit times 16 gives 4096 right? Then shouldn't it mean hbm is 16 times faster?

Sorry if my question is elementary, but it would help me alot. Thanks.
