First AMD Radeon 400 Series GPUs To Start Selling In April
Read more: http://wccftech.com/amd-radeon-4 ... tart-selling-april/
It has only been a couple of months since AMD revealed its next generation Polaris graphics architecture but looks like the company’s Radeon 400 series GPUs are almost ready to start shipping to customers. In fact it looks like we might be looking at April for the very first Radeon 400 series graphics cards to start shipping.
AMD发布下一代北极星架构不久后 R400系列将要开始发售了，预计4月出货。
Lenovo has just announced it’s brand new lineup of Windows 10 YOGA laptops and tablets for 2016. Some of which as we’ve discovered feature configurations with AMD Radeon 400 series graphics cards and will start shipping this April.
联想刚公布新款的Win10 Yoga笔记本（笔记本 平板通用）。其中有些将会使用R400系列显卡。
AMD’s Radeon 400 Series Graphics Cards Are Almost Here
The systems in question are Lenovo’s brand new 15 inch and 14 inch YOGA 510 laptops, which will sell under the Flex 4 name in the US. Both the 15 inch and 14 inch version can be configured with dedicated AMD Radeon 400 series graphics cards. The former can be equipped with an R7 M460 and the latter with an R5 M430.
下面是15和14英寸的Yoga 510笔记本。都配备R400系列显卡 前者是R7 M460，后者是R5 M430。
Sadly we don’t have detailed specifications for these 400 series graphics cards just yet, except that they will feature 2GB of video memory. These could very well be the Radeon 400 series GPUs code named “Weston” and “Banks” that we’ve recently discovered in the Zauba shipping database. Right now we’re stuck with these code names and really don’t know much beyond in terms of specifications or performance. However, if these GPUs are indeed going to ship beginning this April it shouldn’t be too long before all of that information is made available to us.
可惜的是，我们并不知道R400系列显卡的具体规格，只知道显存大小是2GB。R400系列的核心代号是“Weston”和“Banks”（从老朋友Zauba那个印度进出口网站发现的）。
Speaking more broadly of Polaris, AMD’s next generation 14nm graphics architecture. The company is not only promising a historic leap in performance per watt, but has also actually demonstrated this unprecedented jump in power efficiency publicly back in January at CES.
AMD的下一代14nm显卡的每瓦能效，我们并能不知道。
So far AMD has unveiled two 14nm FinFET Polaris GPUs, given the names Polaris 11 and Polaris 10. A small GPU meant to deliver console-class gaming performance in thin and light notebooks and a large GPU, described as a successor to the Radeon R9 Fury X.
两款14nm FinFET北极星GPU命名为北极星11和北极星10，旨在为轻巧的笔记本提供极致的性能。他也是Fury X的继任者。
Polaris Is Efficient, Very Efficient
AMD, has only demoed the smallest member of the Polaris family running Star Wars Battlefront at 60 FPS against an Nvidia Maxwell based GeForce GTX 950 graphics card. The Polaris GPU consumed roughly half the power to produce the same framerate. This huge jump in power efficiency is going to play a crucial role in allowing the company to make really high performance mobile graphics cards. In fact it means a de facto doubling of graphics performance for gaming laptops and even desktops.
AMD已经演示过北极星家族 星球大战：前战 60FPS运行演示。这干掉隔壁Maxwell架构的GTX950。北极星能耗减半，效果不减（相当于双倍性能），这是对游戏本甚至台式机来说是一个巨大的飞跃。
Naturally any improvements in performance per watt often translate directly to improvements in actual performance in all graphics card tiers whether we’re talking about high-end, mid range or entry level products. This is because the power design envelopes stay mostly unchanged for all graphics card tiers. This means that a 250W Polaris GPU should be twice as powerful as a 250W Nvidia 900 series GPU, assuming we see similar power efficiency scaling to what AMD has demonstrated. But Polaris isn’t just about power efficiency as it’s bringing several new cool features.
一般来说，能效的提高直接提升游戏的性能，这意味着250W的北极星能达到2倍于老黄家250W 的GTX900系列的性能。而北极星带给我们的远不止这一个惊喜。
Polaris Is Designed For And Built On Samsung’s 14nm FinFET Process Technology
AMD’s chief technology officer, Mark Papermaster, announced last year that AMD will in fact be leveraging Globalfoundries’ 14LPP process for CPU, APU and GPU products.
FinFET technology is expected to play a critical foundational role across multiple AMD product lines, starting in 2016, GLOBALFOUNDRIES has worked tirelessly to reach this key milestone on its 14LPP process. We look forward to GLOBALFOUNDRIES’ continued progress towards full production readiness and expect to leverage the advanced 14LPP process technology across a broad set of our CPU, APU, and GPU products. – Press Release
AMD later announced Polaris and confirmed that it will be manufactured using the Samsung/Globalfoundries’ 14nm FinFET process technology.
AMD’s Polaris architecture-based 14nm FinFET GPUs deliver a remarkable generational jump in power efficiency. Polaris-based GPUs are designed for fluid frame rates in graphics, gaming, VR and multimedia applications running on compelling small form-factor thin and light computer designs.
14nm FinFET will offer GPU design engineers nearly double transistors to play with in the same area as the current 28nm process. 14nm FinFET also has significantly faster switching speeds, which translates to significantly higher clock speeds compared to current 28nm based GPUs. This is all in addition to the drastic power savings enabled by the smaller feature sizes and the move from planar to 3D FinFET gates.

4th Generation Graphics Core Next Compute Units
第四代GCN架构
The name “Polaris” doesn’t just describe AMD’s 4th generation GCN architecture, but a broad collection of new visual computing intellectual property. For AMD’s 2016 graphics products the company updated all aspects of its graphics IP. Including the addition of support for DisplayPort 1.3 and HDMI 2.0a in addition to h.265 decode at up to 4K and encode at 4K and 60 FPS.
增加了DP 1.3 HDMI 2.0 a H.265 4K编码和4K@60 解码。
When it comes to the GCN ( Graphics Core Next ) engine itself, AMD outlined a number of fundamental features that define the architecture and they include :
– Primitive Discard Accelerator
– Hardware Scheduler
– Instruction Pre-Fetch
– Improved Shader Efficiency
– Memory Compression
——原始丢弃加速器（好像网上也没有确切的翻译）
——硬件调度器
——指令预读
——材质效率提高
——内存压缩
One notable new feature is primitive discard acceleration. Which in no certain terms is AMD’s way of revealing that its upcoming GPUs will add support for additional key DirectX12 features such as Conservative Rasterization.
Furthermore, this list does a great job of showcasing just how advanced modern GPUs have become. Instruction pre-fetch is a technique that’s long been employed in CPUs and it works to improve performance by reducing stalls and unnecessary wait times. So it’s quite remarkable that this technology is now an indispensable part of modern graphics engines. That really goes to show just how complex modern GPUs have become.
It’s important to note though that instruction pre-fetching in GPUs isn’t an entirely new addition, current graphics architectures do support varied levels of pre-fetching. However, these implementations have been traditionally quite limited in nature. With Polaris, AMD is pushing for a more robust solution to more effectively tackle a broad set of scenarios in which pre-fetching can be really advantageous.
一个值得注意的新特性是原始丢弃加速器。 还没有确切的说明表示这是AMD展现其即将到来的GPU将添加支持额外的关键DirectX12特性（比如保守的光栅化算法）的方法。
指令预读技术被长期在CPU上来提高性能通过减少开销和节省不必要的等待时间。
重要的是要虽然指令预读并不是一个全新的特性,但在当前的图形架构是可以支持不同等级的指令预读。
AMD’s New Polaris Multimedia Engines Will Allow Gamers To Stream Games At 4K For No Discernible Performance Cost
AMD 新北极星多 媒体引擎能让玩家在4K下获得更好的游戏体验
Polaris also brings a bunch of new multimedia capabilities to the table. Including the ability to stream games at 4K without any performance cost. Something that AMD’s graphics guru and the head of the Radeon Technologies Group, Raja Koduri is very excited about.
Raja Koduri, Senior Vice President and Chief Architect, Radeon Technologies Group
We have two versions of these FinFET GPUs. Both are extremely power efficient. This is Polaris 10 and that’s Polaris 11. In terms of what we’ve done at the high level, it’s our most revolutionary jump in performance so far. We’ve redesigned many blocks in our cores. We’ve redesigned the main processor, a new geometry processor, a completely new fourth-generation Graphics Core Next with a very high increase in performance. We have new multimedia cores, a new display engine.
In summary, it’s fourth generation Graphics Core Next. HDMI 2.0. It supports all the new 4K displays and TVs coming out with just plug and play. It supports display core 4.3, the latest specification. It’s very exciting 4K support. We can do HAVC encode and decode at 4K on this chip. It’ll be great for game streaming at high resolution, which gamers absolutely love. It takes no cycles away from games. You can record gameplay and still have an awesome frame rate. It’ll be available in mid-2016.
Second Generation Vertically Stacked High Bandwidth Memory
HBM2代
AMD has confirmed to us that while the company remains committed to the High Bandwidth Memory technology it co-invented with its partner Hynix and brought to the market last year, Polaris remains compatible with both HBM/HBM2 and GDDR5 memory standards. Technical marketing lead at AMD, Robert Hallock, explained that they have the flexibility to use either technology as the need arises. As such each memory technology will be employed in the market segments where it makes sense.
AMD helped lead the development of HBM, was the first to bring HBM to market in GPUs, and plans to implement HBM/HBM2 in future graphics solutions.
At this time we have only publicly demonstrated a GDDR5 configuration of the Polaris architecture.It’s important to understand that HBM isn’t (currently) suitable for all GPU segments due to the current HBM cost structure. In the mainstream GPU segment, GDDR5 remains an extremely cost-effective, efficient and viable memory technology.
Polaris graphics cards are set to launch this summer, before the back to school season, on both desktops and gaming notebooks.
北极星显卡将会在进你啊你夏季返校季前发布，对应台式和游戏本都会有产品。
