Navi Rumours... should i really take these seriously?

ANDREW GREEN said:
Navi will be a new custom built chip, probably 8gb of DDR6 instead of 16gb of HBM2. So it may or may not get 1080 performance, maybe it'll be 1070 we will see. I'm not sure I buy adoredTV's leak eitherway

lolwhut? So you state exactly what's in AdoredTV's leak in Navi being a new custom chip with 8GB GDDR6, yet you don't buy the leak? And why wouldn't Navi get 1080 performance?

So many people bemoaning the Radeon 7 saying it's only matching a 2 year old card in the 1080 Ti, yet suddenly Navi can't possibly be 1080 performance, despite the 1080 being over 2 years old. It's 2019 for goodness sake, 1080 and 1080 Ti performance should be old hat.
 
It depends on the die size - if it is 200-250 sq.mm, not only it can reach GTX 1080, but may reach RTX 2080 performance, thus making Radeon VII obsolete.

Oh dear... now the rtx 2060 has muddied the waters even further! 1070ti performance with real time ray tracing at 1080p and $350... am I gonna be tempted by Nvidia again?!

The only thing muddied is the price, it should be $250 so it can take over the old 1060 price point.

I know I buy some high end cards but I don't like seeing new cards being released with the same bang for buck as old cards from the next tier up.

New cards should offer at least 30% more performance for the same price as the old cards they replace.

Let it be more - HD 4890 to HD 5870 results in ~50% performance uplift; HD 5870 to HD 7970 results in >70% performance uplift; HD 7970 to R9 290X results in 50% performance uplift; R9 290X to RX Vega 64 results in 75% performance uplift.

Amen to this.....
One side of me doesn't see reason to get the RVII over the Vega 64, especially given price & perf.
But there is the enthusiasts itch that want to put my hands on that baby and see what I can do with it :D

And you know well that "itch" made me downgrade from the mighty 1080Ti Xtreme to the Vega 64 :rolleyes:

Ummm no, you missed the points of failure,
5870 -6970
And 290/x to fury x,
Fury x to vega 64
Vega 64 to V7.

Well the 7970-290x-Fury x were all on 28nm. Vega 64 is 14nm v 7nm for Vega VII so it's not always as simple these days.

I don't take Radeon VII because it is considerably smaller than RX Vega 64, so can be considered as a die shrink which should be positioned a tier lower, not a replacement in the same performance segment.
Also, the going from GCN 1.0 to GCN 2.0 and from 352 sq.mm on the HD 7970 up to 438 sq.mm two years later on the R9 290X was a good improvement.

You can compare Ellesmere to Vega 20.
232 sq.mm on 14nm to 331 sq.mm on 7nm resulted in 127% performance improvement.

I know was just pointing out it's not always as simple as what you had quoted above me.

These were refreshes on the same nodes. You need to look on only the first generations on n node to the first generations on the n+1 node.

What are you talking about? There are only two refreshes on that list and even then they aren't really refreshes either. The 6970 used the new VLIW4(Terascale 3) whereas the 5870 used the VLIW5 (Terascale 2) The Radeon VII is a refresh of Vega but on a die shink.

The others aren't refreshes at all. FuryX is not a refresh of the 290x, the 390x is. Vega isn't just a refresh of the Fury.
 
Basically I have to buy the VII unless I want to wait another year and a half for a better AMD card. Truly, I think the people buying the Vega 56 & 64 on black friday @ £300/400 were stealing from AMD with those prices.

AMD's gonna look really good, again, at low & mid range tiers, with Navi, but will still miss the high-end spots. Good for most people but I'd still have loved a 2080ti equivalent this year, esp. one not gimped with just 11gb of vram or costing £2.5k.

Have you got a 56/64?

No, 480. I realise now I missed adding some context to "better AMD card". I meant to say above a V64 in performance. Was actually going to get a V64 but decided to upgrade the TV & Sound instead, as it wouldn't have offered me the performance I wanted anyway.

Oh right, I was gonna suggest buying 56/64 and waiting a while, as you quite rightly said they were tremendous value on Black Friday and they can still be bought for very close to those prices anyway. I'm stuck waiting for Ryzen 2 now, probably pair Vega with it, probably go to 1440p while i'm at it.
