Title：AMD Working On An Entire Range of HBM GPUs To Follow Fiji And Fury Lineup – Has Priority To HBM2 Capacity
From: http://wccftech.com/amd-working- ... ow-fiji-fury-lineup
简报：AMD的攻城狮们正在全力工作，试图将HBM用于接下来的产品线省。从高端到低端全方位使用SK海力士HBM。新的产品线也将打入移动市场，包括设计用于笔记本的HBM显卡。
第二代HBM供应量有限，所以AMD要增加最初生产能力来对抗绿队。如果成功，这将使绿队的帕斯卡系列提前进行，但是如果没有HBM2的话，帕斯卡将无法生产。AMD是使用海力士的HBM生产显卡的第一家公司，所以海力士能优先为AMD提供产品。目前尚不清楚AMD能否继续获得海力士的HBM3优先供货权。2016年，HBM2将可以使用，可能大部分的游戏可能会达到4K 60FPS的水平，HBM2将发挥至关重要的作用。而4K显示器在近几年不断降价，也可以让大家买得起，所以4K可能取代1440p成为电脑游戏玩家的主流分辨率。
原文：We’ve received information that AMD engineers are hard at work on a range of GPUs featuring stacked high bandwidth memory to follow Fiji. While Fiji is AMD’s first GPU to feature this new high bandwidth graphics memory standard, it certainly won’t be the last.
The range will span top to bottom solutions featuring SK Hynix’s stacked high bandwidth memory, HBM for short. This new lineup will also serve as the vehicle by which AMD will introduce this new memory technology to the mobile segment with the company’s first ever set of HBM GPUs designed for notebooks.
AMD Working On An Entire Range of HBM GPUs To Follow Fiji And Fury Lineup
The advantages that HBM brings to the table, including the significantly reduced PCB area and improved power efficiency, makes its use in notebooks an extremely attractive proposition. The smaller chip and board area as well as the power efficiency gains that HBM enables would have a more profound impact on notebooks where power and size are much more strict limitations than what we typically see on the desktop. However AMD showed no shyness in leveraging those advantages on the desktop with the compact Radeon R9 Fury X and the even smaller Radeon R9 Nano.
We found out last year that AMD is working on a new graphics architecture that will succeed GCN 1.2 ( Fiji and Tonga ) in 2016. The new family of GPUs based on this architecture are reportedly code named Arctic Islands with a flagship enthusiast GPU code named Greenland. This family is set to debut next year with second generation HBM and on a new FinFET (14/16nm) manufacturing process rather than 28nm which is what all discrete GPUs from Nvidia and AMD are currently based on.
The process node jump makes Arctic Islands a true next generation family of products due to the benefits that accompany any migration to a smaller process node. The significant increase in transistor density, switching speeds and reduced leakage enable faster, larger, more power efficient and more complex GPUs than what’s possible on 28nm today.
AMD Has Priority Access To HBM2 Production Capacity And Is Aiming To Take Full Advantage Of It
Our sources have told us that AMD management has thrown significant weight behind this new range of graphics chips to accelerate its development and time to market. This is we’re told is to take advantage of a deal established with SK Hynix which gives AMD priority to HBM2 capacity which is going to be in limited supply initially. Capturing as much of the initial production capacity as possible would give AMD an edge against its main rival, Nvidia, going into the next generation of GPUs featuring second generation HBM technology. Which is exactly what the company is gunning for.
If successful this would push Nvidia’s Pascal launch schedule back than what the company originally planned. But the time waiting will not go to waste we’ve no doubt. The company has reportedly already taped out its first Pascal chip. However without access to HBM2 the graphics cards based on Pascal can’t produced. This may lead the company to consider the possibility of spending more time working on successive Pascal chips until it can secure enough HBM2 production capacity.
This fascinating dynamic is the result of AMD’s seven year involvement in the co-development of the High Bandwidth Memory JEDEC standard with its partner SK Hynix we’re told. Which is why AMD was the first company to introduce a product featuring HBM. And why the the first generation of the technology is exclusive to the company. It’s not clear whether SK Hynix will continue to give AMD priority access to production capacity with HBM3 and successive generations of the technology. Although AMD is clearly keen on leveraging its exclusivity deal with SK Hynix in the here and now.
While being first to market can be advantageous, going second can prove to be equally favorable. As it would allow competitors to size up their competition and prepare a more appropriate response. We’ve seen this take place time and time again with each generation of GPUs.
We can’t wait for 2016, HBM2 enables memory capacities right times as large as what HBM1 can deliver today and memory bandwidth figures upwards of one terabytes per second. The current flock of enthusiast graphics cards from Nvidia and AMD can run most graphically demanding games like The Witcher 3 and Crysis 3 at 30+ FPS. Next year however may very well be when most graphically intensive games can finally be maxed out at 4K with a more agreeable 60 FPS average and HBM2 will play a crucial part in making that possible. 4K monitors have gone down in price considerably in the past couple of years and continue to become more affordable. 2016 might just be when 4K become what 2560×1440 is today and 1440p in turn replaces 1080p as the new mainstream resolution for PC gamers.
