The design process are around 3 to 5 years on any given product.
However AMD hired and designed ZEN due to Bulldozer simply didnt scale.
I call that learning from their past.
The 400 series has a perfect price/performance ratio for 85% of the customer base so I call that learning from the past.
Everyone makes mistakes its part of the design process and cant be avoided fully no matter how how hard you try. What one can avoid is lying to you and selling you cards that isn't right like 3.5gb 970 and saying it is 4gb and why Nvidia lost the lawsuit. Its not ok when a company sell cards to Apple and they burn their computer knowing they would. Thats why Apple buy AMD cards as that did happen.
So who did learn from their mistakes, AMD or Nvidia?
People worry a lot but we have seen how AMD has done something new here, the design with ZEN and the rtg with the 400 and soon Vega are new ways which just indicate they changed both design and tactics and it as far I can tell have been hugely good for them.
I feel really confident about how AMD have learned from mistakes and are going for a new era of products. Cant judge the future based on the past as thats the fools errand.
Thats all well and good floppy but the Polaris is a let down, it suffered a bad rep from the start with the PCIE issue which has been addressed, its got a horrendous cooler on it again, which throttles its performance and it was simply priced too high, coinciding with the Brexit meant the card was way above the price bracket it should have been in.
I understand what AMD were trying to do, it was unfortunate for them that the Brexit came along and rained on their parade, if the card was cheaper it would have disrupted the market like it should have done, unfortunately its not disruptive at all, despite what AMD and AMD Fanboys will have you believe. Im an AMD fanboy but im also a realist and i realise that Polaris never hit all the points it was supposed to.
Again AMD dropped the ball with Polaris, this time on a few fronts, PCIE power issue, Bad reference cooler, over priced. Just one of those is enough to give a card a bad name.
Also i think the 480 was the 470 pushed to its limit, i think the 470 was supposed to be the main card but AMD somehow felt they needed the 480. Polaris as an architecture seems underwhelming also, sure its better than FIji, as you can actually OC Polaris and get meaningful results from doing so, but it just feels like a revamped Hawaii in regards to the heat and power issue again, when you look at Nvidia and see how much cooler and more efficient their cards are you start to wonder why AMD cant get near them? yes even though AMD carry the extra hardware onboard for DX12 etc that requires power, i still feel AMD cards lack the polish of Nvidia products.
What i am getting at is my expectations for Vega are not how fast its going to be, as i think it will be a decently performing card, but i expect it to come packaged with a horrendous reference cooler and i expect HBM again to be unclockable pretty much, and i expect the card to be priced much higher than is warranted (part of that will be HMB2 costs) will i still buy it? yep, i will probably buy 2 of them, i love AMD cards performance, i just dont like the rubbish they are saddled with. It also means i will have to wait for 3rd party cooled versions like Tri-X etc, but im happy to do that.
Vega will be decent but it will be again hindered by at minimum 1 thing from AMD, and more realistically 2 or 3.
