Until they release game engine updates I don't think you'll see any improvement in performance. Because right now most of them seem to think Vega is a Fiji with higher clocks ? Which is complete BS, rather obviously.

If Vega is barely beating GTX 1080, it has lower performance than Fiji clock-for-clock. Lower IPC in other words. Which is insane.

Not insane. It has a narrower bus and different latency characteristics than fiji. I am pretty sure it needs many specific optimizations to maximize performance which will take several months to be implemented. Same with Fury X. It was slower than stock 980ti even on 4k at launch and now it beats it at 4k and has similar performance on 2k resolution.

Are you saying that the Vega FE performance is what the gaming Vega performance will be? It sounds exactly like that.

A narrow bus with fast memory = a wide bus with slower memory. Also, there are reports that there are bugs with Fury X's performance and technically it is stuck at memory bandwidth around 350GB/s or so.
Also, Vega is equipped with latest algorithms to make much more efficient use of lower memory bandwidths.

No. I am saying gaming Vega will have plenty room for improvements at launch. And yes it wont be that much faster than Vega FE. Maybe sth like 10%.

In theory yes. But different memory = different drivers to reach full performance. I am pretty sure amd hasnt yet finished all the required optimizations. The same thing has happened to 7970, 290x, 3870, 4870, 5870. Amd never managed to provide the full performance at launch.

Yes but those features need work from the driver team to be implemented. And vega may not use bandwidth as efficiently as pascal.

I'm sure that the release RX drivers will be a lot more advanced than the seemingly ancient and made compatible FE drivers.

Indeed, they'd better be a lot more advanced!

You are so wrong. It will be at least 25% faster than FE. It is already on last engineering sample benched at 10% faster than a 1080 on Firestrike. So you are saying there will not be be faster driver by launch time. You are deluded.
Yes you are correct about it taking a 2-3 more months before the ultimate speed of RX Vega is achieved, but by release it will be at least 20% faster than a 1080 since it is already 10% faster on last weeks engineering sample benchmark.

3d mark single benchmark =/= gaming performance across dozens of applications
Beating 1080 by 20% on firestrike doesnt mean that it will do so on average on multiple games. This is not even an official result. (or is it? i dont know)

So far what amd has shown is not encouraging. I am looking forward to upgrade to vega as much as you. I just dont want to set the bar way to high and get disappointing.

Samsung Increases Production of 8 GB HBM2 Memory

https://www.techpowerup.com/235263/s...gb-hbm2-memory

These are for Vega?

Probably yes. Vega will need much higher HBM2 volume than any other product.
