Yes, but also for it to be as fast or faster than the titan xp, it will need more than the 4608 cores it is expected to come.
AMD's higher bandwidth and HBM2 memory is there to compensate for the core performance. Same as the fury X.
Unlike the fury x, it will not have the 4GB memory issue, but then the core count will be its bottle neck instead of memory.

But we will see it only when it release.

I also recall that board partners are free to offer increased memory (16GB HBM2) vs the standard 8GB HBM2 AMD is offering.

The vega10 workstation card was shown to be 12TF with 16GB of HBM2. I don't know if it will be the same on the desktop version.

I also don't see how they are going to offer 16GB HBM2 and 8GB HBM2 versions. The memory is part of the chip. You can't remove it and replace it with your own memory, and I doubt AMD will sell them higher HBM2 amount chips for a few extra $$.

Now if a date is present... Could this be the real deal? (We will know on that day though)


Either way Vega may not be overclocking much, so its better to compared it with a Max OCed TXP, in less AMD optimized title also.

I don't think you can really compare stock vs OC.
But we will see when the card actually comes out.

Vega only has 4096 cores. but the cores are more capable than those in RX 580.


Vega promised a 2x peak performance output, that mean it is most likely twice as fast as Fury X in that sense, given they have the same amount of "cores". If it really scale 100%, It will be approximately 20-30% faster than TXP. However:

1) That is assuming 2x value is true
2) DOOM is heavily optimised for AMD
3) Vega most likely will be bad at OC, Making a TXP with OC much closer in performance.


Either way, even if somehow AMD pull off, it will be not that fast.

The GTX 1080s numbers are slightly underrated. More in the high 70s to low 80 fps range.

Doom runs very well with AMD but also very well with Pascal.
I do not see how 4096 SP card can match 3840 SP card clocked 2GHz. Just not possible unless NCU are nothing like CU. At the same time HMB2 is only 512GB/s so less than Titan Xp. This time around Vega is these specifications are true does not even match Titan Xp in raw power let alone actual power.

You can't compare the efficiency of the stream processors in fiji since that card was heavily pipeline bottlenecked. Hawaii shows better performance per stream processor in comparison to fiji. I think that will be a better platform to start when comparing core efficiency.

We are talking 100% more efficient here over Fury X to match GTX 1080 Ti. Here is the thing. If Vega is 15% slower than GTX1080 Ti and sells for $550 I will get it. Knowing the tech AMD has in Vega I can see it matching GTX1080 Ti in the future.

The image is fake. It's from WCCFtech comments.

If you zoom you will see that the vega logo is a low resolution.

Of course it's fake. If was true it would be the biggest secret ever from AMD.

Fury X has 45% more cores than a 390X yet only performs 20-25% better max, even in DOOM running on vulkan. So, I don't think 100% more performance isn't off the cards. They just need better stream processor efficiency than Polaris and perfect scalability.
