    Smile Dual Core



    Rekan,

    Menurut info dari salah satu reviewer terkenal, dibilang bahwa dual core nya intel akan datang (4th Quarter 2005) akan dikasih nama x20,x30 dan x40, masing2 bekerja pada freq 2,8GHz, 3.0GHz dan 3,2GHz .... codename Smithfield.

    Koq Freqnya turun ya? Disebutkan juga bahwa karena arsitekturnya akan kurang lebih sama dengan Prescott yg mana sudah terkenal panas karena terlalu banyak transistor. Itulah mengapa dia menurunkan freq-nya.....

    Hmm... he's (intel) having lots of trouble though .....

    Utk AMD (codename Toledo), salah satu problemnya adalah memory bandwidth. Tapi mungkin hal ini akan diatasi dengan DDR2 <-- opini saya, seperti yang dilakukan oleh intel.

    Any comments?

    kan sekarang bukan jamanya lagi kebut2tan clock frequency ,walaupun amd clocknya lebih kecil tapi IPC (intruction per clock)nya lebih banyak dari pada intel yang sekarang.

    CWIIW itu artinya apaan yah?

    Re: Dual Core



    AMD kayaknya nggak pake DDR2 de.. masih lama dia pake DDR2.
    Terus, soal bandwidth limit di memory, kayaknya nggak juga de. Soalnya sampe sekarang, AMD kan pake dual channel, terus sampe saat ini, dual channel dan single channel belum kelihatan bedanya, karena memory request nggak gede gede amat. So, kira kira, dual core AMD di socket 939, anggap aja sama kayak 2 buah socket 754 digabung jadi 1.

    Re: Dual Core



    Yup, panas di P4 memang jadi masalah besar buat Intel sampai-sampai mereka merubah "processor roadmap"-nya: Nggak bakal ada P4 clock 4 GHz! Agak ironis memang soalnya Intel berharap P4 bakal bisa digenjot minimal sampai 4 GHz (maksimal 10GHz ). Sekarang mereka sedang cari cara buat menghalau panas ini. Cara satu2nya ya ganti arsitektur. Di arsitektur baru (P5 mungkin??) diharapkan bakal lahir generasi prosesor baru.
    Jadi benar tuh apa kata rekan dimasdw, sekarang nggak jamannya lagi clock gede....adu lari GHz sudah usai..gitu kata bos Intel, Paul Otellini.
    Tunggu aja, tahun depan Intel bakal ngeluarin dual core buat semua segmen, mulai dari desktop, server, sampai notebook. Sehabis GHz war, sekarang dual core war?

    Re: Dual Core



    Hmm..berarti benar ya, mereka sedang mengalami masalah. Itu juga mungkin berarti bahwa mereka mempunyai proc >5GHz di dalam laboratorium tidak benar (ada yg pernah mengatakannya kepada saya, tetapi bukan dari forum ini). Di 3.8GHz aja sudah kepanasan, apalagi >5GHz ...

    Saya pernah baca, Team A-nya intel yang katanya di "keluarkan" dari pengembangan processornya karena menentang policy intel untuk mengejar frekuensi setinggi-tingginya, terus sekarang mereka lari kemana? apa membelot ke amd atau masih di intel? Ada berita?

    cmiiw please, i'm studying ...thanks and peace!

    salam,

    Terus, buat mas Dodi, dia pake arsitektur P6 atau seri-nya CuMine/Banias/Dothan. Andalan Intel berikut adalah Jonah yang merupakan dual core Dothan, diteruskan dengan Merom.

    Kalau si Andy Glew-nya sih dulu kabur ke AMD... sekarang dia tulis buku. Rumornya sih specnya dia katanya di AMD juga bikin pusing kepala.. nggak tahu AMD mau terima nggak spec dia yang gila-gilaan.

    I may be flamed for this post being personal and off-topic, but my friends in the comp.arch newsgroup may be interested to learn that I have changed companies, moving from Intel in Oregon to AMD in California.

    I would like to explain why I choose to change companies, but I probably should not go into details. Obviously, I hope that AMD is a better place for me to work than Intel. I hope that, at AMD, I will be able to be part of a team building microprocessors that will be just as successful, financially, as the processors I have worked on in the past, most notably the Intel P6.

    Mike Haertel says that I should make this post memorable, making pithy comments on some important technical issue. I flatter myself that I am usually able to make such posts. However, I'm tired, and my mind is full of things I am not allowed to post about.

    Obviously, although I am now an employee of AMD, this posting is personal, and does not reflect the position of AMD. In fact, I will probably seldom, if ever, post from my work account again. (I will only post from work on matters that can be considered part of my job.)
    I would like to participate in comp.arch again as I have in the past, but being employed by microprocessor vendors like AMD and Intel posting to comp.arch can be "sensitive" - not officially, but unofficial FUD of saying something wrong leads to a great deal of self censorship. This is regrettable, because I personally learned more from comp.arch and the USEnet than I did from academia. In any case, I will not post until my .net.connectivity is sorted out.

    Anyway, guys, you know where to find me now.

    And, given that I am now living in the Bay Area, I think that it might be neat to meet a few more comp.archers in person.
    The following were my managers at Intel during P6:

    * Bob Colwell, former Intel Fellow; Manager, P6 Architecture
    * Dave Papworth, Manager; P6 Macroarchitecture
    * Fred Pollack, retired Intel Fellow, Manager, Microprocessor Architecture and Planning; Manager, Microcomputer Research Labs
    Ini team dia... Bob Colwell juga udah former. Berarti juga udah cabut.. Fred Pollack udah retired.

    Spec AMD yang dia kasih ada di CV-nya, di quote yang di atas..

    Re: Dual Core



    Belum tahu banget detail-nya. Dari berita yang saya tangkep, tahun 2005 Intel pengen nge-push konsep "Digital home and Office". Ini sebenarnya bukan konsep baru, sudah diperkenalkan sejak IDF 2003. Produk konkretnya ada beberapa, diantaranya prosesor desktop khusus untuk "Digital home and Office" (sandinya Lyndon).
    CPU ini bakal punya kemampuan built-in wireless yang konsepnya sama dengan Centrino. Base-nya masih tetep Pentium 4, tapi dengan cache 2MB,
    PLUS 64-bit extensions. Saya dengar juga ada Speedstep-nya juga lho.

    Di sisi single core, Pentium 4 bakal dapat "facelift" dengan cache memory 2 MB (seperti bahasan kita diatas, buat nge-dongkrak kinerja).

    Untuk dual core mereka punya "Smithfield" (rencananya rilis akhir 2005). CPU dual core pertama dari intel ini punya 2 core Prescott atau mungkin juga core P 4 yang 90nm. Di tahun 2006 mereka baru beralih ke desin baru 65nm (Cedar Mill).

    Di Notebook, seperti kata mas Magician, ada Jonah yang bakal pakai 65nm juga. Saya dengar mereka juga punya chipset baru caligosta dan Alvisto untuk mengadopsi DDR2 dan PCI-Express di Notebook.

    Re: Dual Core



    P4 untuk dual core bakal launch sekitar Q4 2005. Masih lama. Dia bakal pakai dual-FSB. Jurus kepepet memang, tapi effective.

    Terus, Centrino bukan di CPU-nya lho... CPU nya kan Dothan sama Banias.. Centrino itu Wi-Fi-nya ada dibundle di chipset-nya. Nah, bundle CPU dan chipset itu yang disebut sebagai Centrino. Kalau cuman CPU aja atau chipset aja nggak akan disebut sebagai Centrino. Nah, P4 akan mengikuti jejak serupa.. dibundle sama Wi-Fi di chipsetnya. Mungkin dikira Intel kita beli Centrino karena ada bundle Wi-Fi-nya.. ehheheh.. kita liat aja nanti..

    Ini roadmap dari Intel
    http://www.theinquirer.net/?article=20198
    THE LATEST INTEL ROADMAPS seen by the INQUIRER indicate that the launch of its dual core desktop processors - the X20, the X30 and the X40 - will be launched in the third quarter of 2005, suggesting they won't proliferate in PCs until the fourth quarter.
    The dual core chips have now got official Intel names - Glenwood will be called the 955X Express, while Lakeport G and Lakeport P will be called the 945G and the 945P. The 955X Express is due to launch in Q2 next year. That's when the 945G arrives as well.
