DDR - 速度与延迟 DDR 内存本身并不慢,主要考虑的是trades off:DDR 内存优先考虑较低的延迟latency,而不是带宽bandwidth。虽然仍然能够实现高速,但 DDR 的较低延迟对于执行需要快速访问内存的 CPU 任务非常重要,例如运行应用程序、管理操作系统、执行指令以及指示 GPU 计算。 DDR5 是 CPU 内存的最新标准,其数据传输...

游戏主机的CPU就使用的GDDR内存,而核显使用DDR/LPDDR也不是什么意外的事情,只和他们的内存控制器相关...
GDDR5 is a high-end low latency RAM that has a throughput rate of up to 8GB per second. GDDR5 chips are produced by manufacturers, notably Samsung, Hynix, ELPIDA, and Micron. It operates on low power and only requires 1.5V. This feature prevents the system from overheating, and overclock...
不能,GDDR6X延迟两百多纳秒。DDR5延迟5x纳秒,最多8x纳秒。延迟差3~4倍。
而我们知道DDR不仅活着还在紧锣密鼓的张罗马上就要上市的DDR5,这是为什么呢?GDDR为了图像显示和渲染,带宽很大,更省电,但有四个重要的缺点: 1.延迟高。也就是CAS的Latency高,这让GDDR更适合图像处理这种高并发的,大块搬移内存的操作。而像CPU这种几乎完全随机的访问,延迟更加重要。
The GDDR6 memory interface is best described as a high-speed, high-signal-count, parallel memory interface that uses single-ended signaling to communicate with DRAM memory in applications requiring high memory bandwidth and low latency. Included here are such applications as automotive ADAS, graphics...
Do the most More space, with more ways to use it. The world’s first 16Gb graphics DRAM massively widens its scope and possibilities, bringing adaptability and broader applications to the forefront. Welcome to stunningly realistic and latency-free gaming for PCs and laptops, ...
Lowest latency and highest data rates for data-intensive applications The latest, the Cadence Denali PHY IP for GDDR6, is comprised of architectural improvements drawn from previous-generation DDR PHYs and Cadence’s 10G, 16G, and 25G SerDes, achieving breakthrough performance, low energy per ...
