    GDDR adalah RAM untuk graphic card.. Sebab tu gc ada memori, eg 512MB/1GB

    Untuk perbezaan antara jenis GDDR, google je, wiki pun ada..

    ATI dan Nvidia kedua-duanya lebih kurang sama, cuma approach sahaja yang berbeza..

    ATI guna GDDR5 but only with 256-bit
    Nvidia guna GDDR3 but with 512-bit

    Bayangkan macam ni
    ATI ambil cara mudah dengan guna memori yang lebih laju, tetapi saiz width/lebar connection yang sama
    Nvidia guna cara yang lebih susah dengan gunakan speed yang sama, tetapi alter width/lebar connection

    Kedua-duanya tak salah, dan dua2 bagus
    Cara NVidia memerlukan kos yang lebih tinggi, tapi development tu berguna untuk next-generation card
    Kita tunggu dan lihat GT300 nanti

    Boleh jadi jugak sebab memory width tu Nvidia mahal
    Boleh juga sebab percentage yield yang lebih rendah berbanding ATI disebabkan "die" size yang lebih besar

    Contohnya

    ap tue GDDR?? FreeforallG92G92bG80RV770GT200-1

    Die yang lebih besar lebih cenderung ada kecacatan
    Sebab tu Nvidia lebih mahal, nak cover balik kos die yang cacat
    Cuba bandingkan saiz die antara GTX260(GT200) dan 4870(RV770)
    Perbezaan memang besar

    Kesimpulannya, ATI kurang "die" yang cacat, manufacturing cost rendah = murah

    nvidia guna DDR,bkn GDDR,xbyk oem nvidia release gc ngn module gddr,tp,module gddr nih digunakan dlm semua console,sbb cost effective..

    GDDR5 lebih kurang same cam DDR3...GDDR xsama cam DDR,GDDR2 xsama cam DDR2,GDDR3 xsama cam DDR3 and so on.....huhu,ada phm??

    i guess nvidia pun guna GDDR3.. cuma huruf "G" tu tak ditulis

    kalau tak silap Geforce 6800 first sekali pakai GDDR3
    then sampai sekarang nvidia masih guna GDDR3..yang diubah cuma saiz memory, clockspeed, bandwidth..

    Geforce FX 5700 Ultra start pakai GDDR3.. Then 6800 Ultra
    Kemudian baru card seterusnya, termasuk 6600GT

    corrected

    senang citer "G" goes to graphic,GDDR,graphic double data rate lol:lol:...GDDR nih higher clock freq bbanding ddr,due to graphic needs,better power efficiency...pergh..tech skrang nih..mcm2 ler..XDR la,GDDR Rolling Eyes

    tengok la camne GT300 nanti.

    alangkah bagus kalau desktop diasa leh gune FBRAM. desktop yang aku jumpe support FBRAM cume Mac PRo je. cesss.

    huhuhu. harge FBRAM aku rase boleh beli Honda EX5 seken tu tuk sekeping. tak berape sure plak. tp mmg lg mahal la dari ape jenis DDR pon.

    then it will be another story about Quad Data Rate

    QDR vs DDR?
    GDDR5 vs GDDR3?

    memory bandwidth 4890 lebih rendah daripada GTX 285
    walaupun 4890 pakai QDR memory dan GTX 285 cuma pakai DDR memory

    ATI 4890 pakai GDDR5 dan QDR at 975MHz@3900MHz effective at 256-bit
    GTX 285 pakai GDDR3 dan DDR at 1242MHz@2484MHz effective at 512-bit

    banyak perkara yang perlu dipertimbangkan, banyak variable
    tak boleh compare sama ada GDDR3/GDDR5 shj

    Sebab tu aku kata tunggu GT300 keluar
