두가지 놀라운 모습이네요. 빨간색 Nvidia 정말 무시무시하게 오르네요. 이 블루오우션에서 인텔만 계속 하락. 굳이 비교하면 물반 고기만인데 아무것도 못잡고 집에가는 그런 모습일련가요?

인텔 Data Centen 1년 매출은, 2018부터 이미 더 늘어나지 않는 상태였네요. 2024년에는 12-14B정도로 끝날지도 모르겠네요.

  • 2023: $15.52 billion
  • 2022: $19.2 billion
  • 2021: $22.7 billion
  • 2020: $23.5 billion
  • 2019: $23.5 billion
  • 2018: $22.99 billion

인텔을 AMD와 비교해도, 2024 Q2에 AMD는 $2.8B, 인텔은 $3B 거의 같고요. 다음분기는 최로로 AMD가 Intel을 data center 매출에서 넘어서게 됩니다.

AMD가 Data Center매출 호조와 guidance를 높인것에 힘입어 전체 반도체 주가를 견인하는 역할을 했습니다. 그러나 정작 본인은 NVidia에 비해 주목을 덜 받는 웃픈일이 생겼습니다. ㅋㅋㅋㅋ

장중에는 AMD는 상승분을 다 반납하고 2%대도 있었고 그 와중에 NVidia는 계속 +10%로 폭등중.

AMD정도가 이렇게 좋다면 NVidia는 얼마나 더 좋을까 이렇게 사고가 흘러가는것 같음.

엔비디아(nvidia nvda)정말 무섭도록 빠르게 성장하고 있습니다. 마켓캡 Market Cap으로 이제 두번째로 큰 회사가 되었습니다.(그리고 다시 3번째로 되었지만). 두번째로 큰회사인데 앞으로 1년간 성장률로는 넘사벽이라 가장큰 회사가 되는것도 시간문제라고 보여집니다.

리눅스에서 게임은 생각도 못할때가 있었는데, 그래도 돈많고 software 인력이 더 많은 NVidia가 쬐금 더 낫은 적이 좀 있었던것 같은데, 요즘 서치해 보면 리눅스 사용자들 사이에서는 AMD가 더 많이 선호되고 있어서 깜짝 놀랐음.

저는 게임을 자주 하지 않지만 lightroom/photoshop, 오디오편집, 비디오편집은 자주하는 편입니다. hw acceleration(GPU)를 쓰면 확실히 리스폰스나 rendering시간이 줄어들어서 좋은 비디오카드가 선택하는 것이 필요하지요. 업그레이드를 고려하고 있는데 상당히 갈등중입니다. 아무래도 desktop이 같은 값이면 빠르지요. 그런데 항상 집에서만 해야하니까 빠른게 별다른 의미가 없어집니다. 잘때 걸어놓고 자면 되니까요.


노트북의 장점은 들고 회사에 가서 좀하다가 걸어놓으면 된다는 점도 있습니다. 속도는 반으로 줄지만 이동성이 좋아서 아웃풋을 공유하게되면 더 빨리할수도 있을것 같습니다. desktop은 집에와서 올리던지 해야하니까요.

--------------------

비슷한 가격대에 시스템을 비교해보면 그래픽 카드로는 nVidia Geforce GTX 980m과 GTX 1070으로 비교가 됩니다. 게임을 거의 안한다는 가정에서는 노트북이 맞는것 같지만 새로나온 재품이 땡기기도 합니다.

비디오카드 벤치마크를 보면. http://www.videocardbenchmark.net/


--------------------

CUDA programming까지 생각한다면 AMD Radeon은 고려의 대상도 안되네요.

GTX 980m의 CUDA 코어수는 1536이라고 하네요.

애플이 제품만 잘 만드는 것이 아니라 생태계를 잘 만들어서 들어오면 빠져나갈수 없고 자꾸 애플 제품만을 사게하는 기술로 지금의 자리에 있는 것이지요. 삼성은 그것 못해서 죽어라고 HW만 만들고, 잘 팔아도 맨날 위기라고 하는 것이고요.


그래픽 세상에서 기술력도 중요하지만 이런 생태계를 아직 만는 기업이 없어서 주구장장 치킨게임만 하다가 NVidia가 CUDA라는 GPU API이자 생태계를 만들었는데, 애플처럼 이미 게임의 판도를 업은것 같습니다. AMD-ATI가 이미 죽은 기업으로 돈도없고 투자할 여력도 안되는 입장에서 절대 따라갈수 없는 상황이 된것이지요.


게임하려면 DirectX, OpenGL, OpenCL 지원 GPU를 찾기 마련이지요. 게임만 하려면 새로 나온 GPU중에 적당한 가격만 고르면 AMD던 NVidia든 큰 차이는 없다고 생각됩니다. 게임 이상의 뭔가 더를 원한다면 이제 CUDA 지원 레벨까지 check하게 됩니다. 당연히 CUDA는 NVidia만 지원하지요. CUDA encoder/encoder는 다른 스탠다드 encoder/encoder보다 훨씬 효율적이고 강력합니다. 헐, 그래서 영상 편집, 사진 편집 system은 CUDA 지원 HW/SW가 아주 절실합니다. 학교나 과학자를 위해서도 CUDA는 아주 중요하지요.


요즘 핫한 AI(인공지능)과 machine learning을 위한 환경에서 CUDA는 어떠한 platform보다 우수합니다. 헐~ 물론 이런 쪽은 전문가들과 전공자들을 위한 것이라서 수요가 얼마나 될까하지만, 맹목적으로 추종하는 사람까지 생겨나는거 보면 이미 AMD는 따라올수 없는 상황이 된것 같습니다.

그런데 CUDA가 배우기가 쉽지 않다는 것은 함정! C++11 먼저 배우고 오라는 불친절한 엔비디아.

제 노트북이 가진 Nvidia Quadro K1000M은 CUDA 지원버전이 아주 불확실하네요. 지원는 하겠죠.

Fastest growing interface is Facebook Lite - app for people on low bandwidth connections


More than 8B daily video views on FB; expect video to be the most engaging online content over the next few years - continuing to innovate here.


Introduced "M", a digital assistant that will use AI to help people complete tasks


Internet.org rolled out to 29 countries, more than 15M people online


Revealed Aquila - first aircraft designed to beam internet into communities down from the sky


Plan to ship the Oculus Rift headset early next year. Gear VR (with Samsung) will release this holiday season.  Will continue to invest in immersive experiences and expect this market to be similar to smartphones and PCs as the next big computing device


--------------

Google

Announced new public holding company - Alphabet - on August 10. New operating structure is being introduced in phases. Expect to disclose Google as a single segment and all other Alphabet businesses combined as "Other Bets" beginning in 4Q15. Other Bets will include Access & Energy, Nest, Life Sciences, investments and incubation efforts (i.e. driverless cars)


Expect CapEx to increase next year in Google and Other Bets, in particular Access & Energy


Headcount increased by 16% YoY and 5% QoQ, majority are engineers and product managers


Strong mobile momentum in emerging markets - India is #2 country for mobile search behind the US


Investments in machine learning and artificial intelligence is a priority


Remain focused on "solving the biggest problems and solving them at scale and that present sizable potential revenue opportunities"


Rolling out Android Marshmellow, best-performing release yet. 1.4B 30-day active Android users around the world


New device & platform announcements: Nexus 6P, Nexus 5X, Pixel C - first Android tablet built N2N by Google (full size keyboard with portable tablet); Creating new platforms for newer areas of computing such as Android Wear; Android Auto, the IoT platform, and Chromecast update

--------------

Intel

Higher than expected revenue was driven by higher notebook and desktop ASPs. Ramping 6th generation core microprocessor (Skylake). 


Remain on track to improve mobile profitability by $800M; 75% of that goal has already been recognized


Data center, non-volatile memory, and IoT groups all posted double-digit growth YoY. Memory grew 20% YoY


Higher 14nm costs than expected; ramped Ireland factory too early with first wafters being expensive


Sales in China down slightly, more of a consumer mix than enterprise - across all different segments


Believe they undershipped in notebooks and desktops compared to industry TAM


For full 2015, memory is expected to grow at fast pace; Data center and IoT will exhibit strong growth, but the annual growth rate for all three will be lower than expected due to weaker macroeconomic growth


7360 next gen modem will ship by end of this year; product announcements next year; first of SoFIA LTEs next year; SoFIA w/ Intel 14nm 2H of next year.


Believe they can keep up long term mid-teen level growth for data center group

벤치마크가 system을 다 대변할수는 없지만, CPU benchmark와 GPU benchmark 두개를 동시에 보는 것은 시스템 성능을 볼수 있는 좋은 측면인것은 맞지요,

Qualcomm이 물량면에서 독보적이었는데 작년에 ARM이 완전 많이 따라왔네요. PowerVR은 Apple에 들어가면서 물량이 무식하게 늘었었고요, Apple이 깐깐하게 선택하고 관리할테니 실제적으로 가장 advance한것이 아닐까 생각됩니다.

역시 GFXBench결과로 Apple IPad에 들어간 PowerVR GX6895이 넘사벽이네요. 이건 desktop 왠만한 GPU와 비교해도 당당할것 같은데요. ARM Mali와Qualcomm Adreno가 차이거 거의 없네요. ARM solution이 이정도로 많이 따라왔나요.

 

3D관련 benchmark라고 보여지는 부분에서는 Tegra가 단연 최고네요. IPhone6에 들어가는 PowerVR GX6450이 엄청 뒤지는것을 보면 Apple이 mobile에서 3D의 중요성을 크게 생각하지 않는거라 보여집니다. 반대로 NVidea는 시장도 없는 3D성능에 계속 목을 맸기때문에 모바일 시장에서 망했었다고 봐도 되겠네요. ARM Mali가 상당한 성능을 보여주네요. ARM이 GPU로 돈을 많이 벌것으로 생각되네요. License정책같은것을 알면 도움되겠네요.

 

Intel과 NVida는 아직까지 mobile까지 확장할 준비가 안되어 있네요. Clock이 너무 놓고 소비전력이 너무 높습니다. 퀄컴의 강력한 경쟁자는 ARM이 되겠네요. 독보적으로 좋을줄 알았는데 거의 비슷하다고 보여지고 ARM 솔루션이 좋은 부분도 있네요. 삼성 갤럭시 S6에도 ARM Mali 새로운 버전이 들어갔을텐데, 성능이 정말 궁금합니다. Mali-T760. 물론 퀄컴 S810에도 어마어마한 Adreno가 들어가있지요. Andreno 430. 발열이 좀 있다고는 하는데. ㅋㅋㅋ. S808에는 Adreno 418.
