DDR(DoubleData Rate):DDR SDRAM是目前最常见和广泛使用的DRAM类型之一。它采用双倍数据传输技术,能够在每个时钟内传输两个数据位。DDR按代称为DDR1、DDR2、DDR3、DDR4等,每一代都有不同的频率和带宽,性能逐步提升。 GDDR(Graphics Double Data Rate):GDDR是专门为图形处理器(GPU)设计的高速DRAM类型。它在DDR基...
SDRAM SDRAM是Synchronous Dynamic Random Access Memory(同步动态随机存储器)的简称,SDRAM采用3.3v工作电压,带宽64位,SDRAM将CPU与RAM通过一个相同的时钟锁在一起,使RAM和CPU能够共享一个时钟周期,以相同的速度同步工作,与 EDO内存相比速度能提高50%。SDRAM基于双存储体结构,内含两个交错的存储阵列,当CPU从一个存储...
About memory What’s the difference between SDRAM, DDR, DDR2, DDR3, DDR4 and DDR5?Updated April 16, 2025 in About Memory All desktops, laptops and tablets use random-access memory (RAM) to store the short-term data they need to function. As computers evolve, RAM improves too. ...
表1. 不同代DDR的比较 DDR4比DDR3有什么优势? 较低的功率 DDR4模块更加节能,与DDR3工作电压1.5V或1.35V相比,其工作电压仅为1.2V。降低的功耗可节省大量功率,并允许以更高的速度运行而无需更高的功率和冷却要求。 更高的模块存储密度 DIMM的存储密度从2 GB开始,最高可达128 GB——相较DDR3从512 MB到...

DDR3 Frequency Range– 800-2133 MHz. While DDR3 starts at 800 MHz, it was generally sold starting around the 1066 MHz range or higher to be a more meaningful upgrade over DDR2. This standard was phased out in 2015. DDR4 Frequency Range– 1600-5333 MHz. ...
This application is a free memory benchmark tool and it supports DDR5, DDR4, DDR3, DDR2, DDR1 and SDRAM types. It usually doesn't take long before the result of the benchmark test is shown on the screen. The speed is revealed in MB/s. Benchmark programs usually measure theoretical ...
