现在有国产颗粒的DDR5内存了么？
现在有国产颗粒的DDR5内存了么？如果国产出来了，会是DDR5降价的拉手么？ 今年试产了，但还没上市 现在4800频率DDR5普通的16*2套条，我看有6XX多就能收到了……
4800频率的DDR5战3200频率的DDR4还是没问题的吧
所以感觉差价也不是很大样，也就是100块的价格差距 国产DDR5上市再过两年吧 T3-DiDi 发表于 2022-11-23 09:06

你是不是在作夢？
DDR5 4800真的就很普通喔，要能看也是要5200收參數開始才算跟DDR4能競爭
另外DDR5顆粒最大宗出貨還是美光，中國產DDR5要打過美光的量非常難，美光速度難看，但出貨量非常大，目前做差異化都是速度上做文章，國產產能沒有速度也沒有怎麼打？ 本帖最后由 xsdianeht 于 2022-11-23 13:11 编辑
ddr5 4800只能打ddr4 2666，还是时序烂的那种
只有笔记本平台内存没法超，换ddr5提升还行 DDR5 6000 以下基本不用看
现在买来都是超着用的

内存就比个带宽和延迟，带宽没什么好比的，D5吊打D4，游戏主要还是看延迟，带宽增加也会有加分，但不会有质的飞跃，我粗略测试过几个手里有一个比较雷的137K止步7000 C30，还有一个比较雕的139K可以7800C30，所以我以13代13700K为例，相对12代137K延迟多1-2ns，139K要比137k延迟高5ns左右，3600以下D4和6000以下的D5没测过，从3600起，普通的3600 C16和C18的延迟差不多对标6000 C30和C32，延迟基本在58-61左右，3600C14这种bdie对标6400 C30，延迟都是在54-57，3900-4000 C14或者C15差不多对标6800C30 7000 C30左右，延迟都是在50-52左右，剩下的139K测试的，4300 C15的可以对标7800 C30，延迟在52-53，折合成137K看大约就是47-48左右，测的时候ring都是按照48来的，如果ring超到50，再减少大约1ns DDR5 提升最大的肯定是集显，集显的带宽需求被满足度比DDR4的时候好太多了 fyc858 发表于 2022-11-23 15:34

感谢分享，看了你这个对比测试，还真没啥换的必要。我那套鱼竿厂的条(长鑫颗粒)16g*2非套条，小超到3600 CL16 延迟56.6ns，差不多能对标6000 C32左右的ddr5。DDR4价格500多点，DDR5要2倍不止了吧。 xavier_cx 发表于 2022-11-24 16:22

D5价格确实要2倍不止，但就算是超级大雷的小绿条adie随便也能7000 C30哦，D4高频条还能一战，普条的话也就只能省点钱心理安慰一下吧，用D5的人绝不会满足一下6000 C30的，这还不如用D4呢[偷笑] 本帖最后由 gartour 于 2022-11-24 20:26 编辑

DDR4对于DDR3也是一样，越老的内存时序越小，问题是现在还有谁用DDR3么？

我觉得应该是D4到D5这个跨度的时候，CL值拉的太大了。
DDR3我记得普遍都是CL9或CL10的样子，换到DDR4时候也就刚翻倍CL18
但初期的DDR5-4800的CL值一下就到48或50了，相比普通的DDR4的CL18来说，都快接近三倍了。
我个人的简单算法来看，应该是要打3200-CL16的D4，得要6400-CL32的D5 所以现在普遍的4000-CL18的D4，得要8000-CL36的D5才能打，我不知道对不对…………？

不对。这两者只是刚好延迟相等，但是DDR5的带宽已经翻倍了。
