    Samsung Unveils 1600MHz GDDR2 Memory Chips

    Samsung Electronics has announced production of its 256Mb Graphics Double Data Rate2 (GDDR2) SDRAM. The 256Mb capacity will enable building graphics cards with up to 512MB of memory using PCBs of typical sizes. Besides, the 1600MHz DRAM chips will allow extremely fast graphics cards.

    Samsung claims that the new devices had already been supplied to leading graphics card manufacturers, suggesting that the actual products with such amazing memory are not too far away. I believe that we will hardly see any graphics cards with 512MB of mind-blowing fast memory in late 2003 or early 2004, but a year from now there definitely will be high-end graphics products with 512MB of memory. Such graphics cards may be based on the successors of the NV40 and R420 designs, for example.

    Samsung’s GDDR2 devices incorporate a number of new technical features, such as On-Die-Termination (ODT), Off-Chip driver-Calibration (OCD) and posted CAS to boost performance by up to 50% over graphics DDR SDRAM.

    GDDR2 SDRAM at 1600MHz in 128-bit configuration is capable of providing of up to 25.6GB/s peak bandwidth, while in 256-bit configurations, the new type of memory will bring up to astonishing 51.2GB/s of throughput.

    Samsung has introduced GDDR2 SDRAM ahead of competition by developing the industry’s first 1000MHz 128Mb GDDR2 SDRAM in July 2002. The chips were adopted by NVIDIA Corporation in its unsuccessful GeForce FX 5800 graphics product. Samsung’s full-scale production of the next generation graphics DDR SDRAM in the second half of 2003 will further accelerate its advanced graphics memory business.

    Update: Samsung has delivered 10000 of these memory chips to Nvidia for NV40 test samples.

    Yes and the 4600 is the fastest GF4 card.....

    A 4800 is a 4600 with 8X agp. (300Mhz gpu)
    A 4800se is a 4400 with 8x agp. (275Mhz gpu)

    Ah so the SE is the slower one....

    4600 based card will always be the better choice as it comes with faster ns rated ram and will overclock much higher than the 4400 or 4200. I have seen 4600s with RAM from the stock 600 or so to 700-750mhz.

    <center>NV40 AA</center>

    The NV40 supports "Stochastic organised grid" while randomising fetches for AA blocks. Should this turn out to be true, then the NV40 will probably have an edge in MSAA IQ against the R420. Please note that this information was reportedly leaked and originally posted on a Russian site, so it should be treated as a rumour and not fact.

    The Inquirer has posted a photo of what it claims could be Nvidia's next generation NV40 graphics card.

    <img src="http://images.tweaktown.com/news/news_nv40.jpg">

    The card uses ultra high speed GDDR3 memory modules from Micron Technology. A Micron official confirmed that it is GDDR3 running
    at 800MHz, giving a data rate of 1.6Gbps and that it will be in full production Q1 2004. Micron suggests no extreme thermal cooling of these memory modules will be necessary.
