AMD Radeon Vega 確定在 Computex 2017 亮相 - 3C

相較 Radeon Vega Frontier Edition，大家更想見到 Radeon Vega。

遊戲市場可能對 Vega 架構顯示卡相當期待，但這款產品到底何時登場，已經成了一個謎。

雖然 AMD Radeon Vega 與 Radeon Vega Frontier Edition 同屬於 Vega 架構 GPU，但
實質上兩者面向不同層面的應用。以 Radeon Vega 而言，它屬於遊戲用顯示卡，在顯示
卡的 BIOS 與 PCB 線路設計（或許有，也或許沒有）部分就會與針對專業應用的 Radeon
Vega Frontier Edition 有些許不同。



16GB HBM2 記憶體的 Radeon Vega Frontier Edition 公佈後，引起了一些聲浪，這主要
是何以遊戲卡仍未登場所致。Raja Koduri 在 Reddit 與用戶討論時，進一步透露了更多
Radeon Vega 的訊息。

We’ll be showing Radeon RX Vega off at Computex, but it won’t be on store sh
elves that week. We know how eager you are to get your hands on Radeon RX Vega
, and we’re working extremely hard to bring you a graphics card that you’ll
be incredibly proud to own. Developing products with billions of transistors a
nd forward-thinking architecture is extremely difficult — but extremely rewar
ding — work. And some of Vega’s features, like our High Bandwidth Cache Cont
roller, HBM2, Rapid-Packed Math, or the
new geometry pipeline, have the potential to really break new ground and funda
mentally improve game development. These aren’t things that can be mastered o
vernight. It takes time for developers to adapt and adopt new techniques that
make your gaming experience better than ever. We believe those experiences are
worth waiting for and shouldn’t be rushed out the door. We’re working as ha
rd as we can to bring you Radeon RX Vega.

On HBM2, we’re effectively putting a technology that’s been limited to super
expensive, out-of-reach GPUs into a consumer product. Right now only insanely
priced graphics cards from our competitors that aren’t within reach of any g
amer or consumer make use of it. We want to bring all of that goodness to you.
And that’s not easy! It’s not like you can run down to the corner store to
get HBM2. The good news is that unlike HBM1, HBM2 is offered from multiple mem
ory vendors – including Samsung and
Hynix – and production is ramping to meet the level of demand that we believe
Radeon Vega products will see in the market.
不需擔心太多，因為 AMD 確定會在 Computex 2017 公佈 Vega 架構與 HBM2 記憶體的 R
adeon Vega 顯示卡；Radeon Vega Frontier Edition 規格如下：

– 64 Compute Units
– ~ 13 TFLOPS Single precision compute performance（FP32）
– ~ 25 TFLOPS Half precision compute performance（FP16）
– ~ 90 Gpixels/s Pixel Fillrate
– ~ 480 GB/s Memory bandwidth
就我們知道的，目前 Vega 架構 GPU 確實擁有 3 顆晶片，而它們分別是 C0（XTX）、C1
（XT）以及 C3（XL），但確切的 Codename 目前並未掌握，但可以確定的是，Radeon Ve
ga 初期將只會提供公版樣式。

至於想知道更多硬體規格、售價與上市資訊，現階段只有等待 AMD 在 Computex 2017 的
全球記者會，也就是 2017 年 5 月 31 日早上 10 點。

全文：
At COMPUTEX 2017, AMD would like to invite you to our press conference, starti
ng at 10 a.m., May 31st at The Westin Taipei, to hear AMD President and CEO, D
r. Lisa Su, and other senior AMD business leaders, share information on the la
test set of high-performance AMD products and technologies for PCs, immersive
devices and datacenters.

The past year has seen AMD bring innovation and competition back to the high-p
erformance desktop market with the release of Ryzen™ processors, as well as f
urther strengthening its consumer and professional graphics offerings, with th
e introduction of the Radeon™ RX 500 series GPUs, designed to enable optimal
experiences in modern games and smooth VR experienced. With so much more plann
ed for 2017, we look forward to sharing new details concerning the AMD line-up
of 2017 world-class products, designed
to deliver immersive experiences and high performance innovation, as well as t
he ecosystems, both OEM and channel, that will support them.

最後發一下raja在ama證實的消息，reddit整理的重點，以下原文：
Thought I would recap the information that has been confirmed during the RTG V
ega Frontier AMA today.
Main goal of Vega was to create an architecture that can handle large data set
s and game at 4K at 60fps.
The demo during Financial Analyst day was an air-cooled Frontier Edition, not
an RX Vega card. There will be water cooled versions of Vega that will run sli
ghtly faster.
Frontier uses 2 x 8GB stacks of HBM2.
Both HBM1 and HBM2 provide plenty of bandwidth.
Raja will look into OC'ing HBM2 and a 16GB RX card.
RX Vega will be shown at Computex. It will not be available the same week but
nothing else has been ruled out.
Frontier runs comfortably using 1x6-pin and 1x8-pin but RTG put 2x8-pin on the
production card for more headroom.
Raja is keeping his beard until Vega launches.
Infinity fabric allows for the joining of multiple engines on a single die, an
d offers high bandwidth and low latency. There has been no mention of using In
finity fabric with multiple GPUs.
Frontier was designed for an array of workload usages., RX Vega is for gaming
and will be faster than Frontier.
Vega will support Tensorflow, Cafe2, Cafe, Torch7 and MxNet via MIOpen.
Pro versions support hardware virtualization. He did not state out right if th
is included Frontier/Vega or or not.
The High Bandwidth Cache Controller (HBCC) helps increase minimum framerates a
nd can improve performance even more if it's specifically coded for.
Developing drivers for GPUs is really hard.
Raja expects to grow ROCm to improve machine learning and compute. Another ROC
m comment.
Raja replies to a comment regarding particle physics simulation, saying this w
ill be improved via the new cache and infinity fabric.
New geometry pipeline in Vega improves throughput per clock cycle and will req
uire no extra work on dev's part to utilize.
Radeon Vega Frontier will be the fastest single GPU solution for compute.
Radeon Instinct will provide dramatically better performance per dollar compar
ed to the competition
RX will have different drivers than Frontier that are optimized for gaming as
well as additional goodies.
Vega is the first GPU architecture to use Infinity Fabric and is in no way a r
e-hash of Polaris
Radeon Chill will continue to be improved and will be updated soon.

簡單翻譯一下較重要的
1.computex會展示vega但不會在那周上市
2.Radeon將提供與對手相比每美元更好的性能(簡單說cp值更高)
3.之前的Frontier用雙8pin
4.到vega上市前，他都會留著他鬍子
5.vega主要目標是在4k 60 fps運行遊戲及large data
6.Financial Analyst day展示的是空冷Frontier edition,不是Rx Vega card,將會有水
冷的Vega版本
7.Vega是首個集成Infinity Fabric的GPU。可以在同一塊芯片上放入多個不同引擎，還帶來了低延遲高帶寬互連，可以把不同IP（以及友商IP）高效地放在一起。
單ASIC上集成多GPU的設計還沒被提及，但是有可能的。
(膠水也可以拿來黏gpu的意思嗎？
雙核膠水gpu的時代要來了？
有人能說明一下嗎QQ)
8.Vega架構GPU有3種芯片，分別是C0（XTX）、C1（XT）以及C3（XL）
9.Radeon Vega Frontier（Vega FE）在計算方面將會是最強單卡。
10.如果你主要想玩遊戲，還是建議等一等，後面會有更低價且遊戲優化更好的Radeon RX Vega顯卡。
