| Samsung Touts 4GHz Memory for Graphics Cards Samsung Electronics, the world’s largest producer of memory, presented at the International Solid-State Circuits Conference (ISSCC) its new GDDR4 memory chips that operate at about 40% higher speed than the GDDR4 was initially estimated to, but uses more power. http://www.xbitlabs.com/news/memory/...221054151.html

| I think ATI needs that for the UBER edition. |

| Um, ouch? 1gb of 2v GDDR4 is alot to add to the power requirements of a overclocked x2900XTX... First time I've even heard GDDR5 mentioned as well. Any bets we'll have DDR4 on the desktop by the time GDDR5 rolls around? |

| yes but considering the insane data bandwith at 2 GHz it is worth it, right now 1.1 are R600 spec |

| True. But, here's a genuine question: The best DX9 cards were starting to show a real need for 512mb at the higher resolutions like 1920x1200 with extra eye-candy running. Flash forward to the 640mb and 320mb DX10 part GTS cards, and suddenly memory size doesn't seem to matter much again. Except for Quake4 using uncompressed textures there is a very surprisingly little difference at 1920x1200 resolutions between RAM sizes. I was under the impression nVidia was already supposed to be more RAM bandwidth limited due to their architecture as well, so given these two points... Will ATI's DX10 cards even show any improvement with RAM at those speeds? Let alone 1gb of it instead of 512mb, and they already have a 512bit wide bus now. I'm genuinely curious, am I missing something obvious? RAM size doesn't seem that critical anymore, even at 2560x1600 some games aren't showing above a 2% difference going by Anandtech's article. I'd tend to think this would directly relate to memory frequency as well? Last edited by Kougar : 23rd February 2007 at 11:37. |

| Grr, hadn't even finished editing my post yet. I'll have to read a few more reviews I guess... nonetheless, I still say the impact from the drop in RAM size isn't showing the effects it should. |

| I think the question is always how much cheaper the 320MB cards will be. If the difference is too small they are useless. |

| $50 cheaper I think
