Although it’s a few years behind schedule, the final specifications for DDR5 memory have been released. The JESD79-5 DDR5 SDRAM standard was originally supposed to be released two years ago (2018), but now, new hardware based on the standard is expected to arrive in 2021 (late 2020 if we’re lucky). There are a number of key improvements with DDR5 compared to DDR4, which will be increasingly beneficial given the rise of high-performance computing and the bandwidth needs of those platforms. Some of those enhancements include: Maximum die density has been quadrupled from 16Gb to 64Gb A single DIMM can accommodate dual 32-bit channels versus just a single 64-bit channel Burst lengths...

It's about that time again in the desktop market to switch to a new memory standard. We first began the transition from DDR3 to DDR4 six years ago, and now memory suppliers are laying the groundwork for the leap from DDR4 to DDR5. So, what kind of advantages will DDR5 offer over its predecessor? Well, SK Hynix is claiming that DDR5 will ultimately offer twice the bandwidth currently available with DDR4 modules. With processor core counts increasingly skyrocketing on modern processors (consumer desktop processors can hit 16 cores and 32 threads, with prosumer platforms hitting the 64-core/128-thread), SK Hynix says that the next-generation DDR5 is poised to help satisfy these bandwidth...

The official introduction of AMD's Ryzen 3000 Zen 2 processors and the accompanying X570 chipset are just days away. We already know quite about the processors and supporting chipset courtesy of leaks, and today we're learning about official memory specs for the Ryzen 3000 desktop processor family. According to momomo_us, which has already provided us with a multitude of leaks on upcoming Ryzen and Radeon Navi products, Ryzen 3000 processors will include official support for the JEDEC DDR4-3200 memory specification. For those keeping score, first-generation Ryzen 1000 processors (Zen) supported up to DDR4-2666, while second-generation Ryzen 2000 processors (Zen+) bumped that to DDR4-2933.... Read more...
JEDEC announced an update to the the JESD235 memory standard that deals with the second generation of high bandwidth memory (HBM). This update brings two key feature enhancements to the standard. First, it raises the capacity limit for each device to 24GB, and it also raises the speed threshold to 307GB/s. If you are unfamiliar with HBM memory, you should know that it was first introduced in 2013 as an ultra fast alternative to more traditional DDR RAM. HBM differs significantly from DDR RAM, in that it operates at relatively slow clock speeds but over an enormous bus that is typically 1024-bit wide. This creates a plethora of bandwidth, and the original HBM standard was able to attain speeds... Read more...
A mere month after DDR4 was introduced for the first time on an AMD platform (Ryzen), the memory guidance organization JEDEC has decided to reveal its plans for DDR5. That's right: nothing can stop the progression of technology. As soon as we have something fresh to enjoy, the next big thing is right around the corner! This probably won't surprise many, as it has been a theme from one generation of DDR to the next, but DDR5 is going to be two times faster than DDR4, and of course more power-efficient (which should come in handy for mobile devices). The current highest clock JEDEC allows before "overclocking" takes over is DDR4-2400, with timings ranging from 15~18 for the CAS latency, as well... Read more...
Is the world okay as-is with just DDR2 and DDR3 memory? Perhaps. We could get by, yes, but what about pushing the envelope? What about faster, faster, faster? Well, it's about time for memory to take the next major leap in speed. JEDEC, a known name in the development of standards for the microelectronics industry, today announced the initial publication of its widely-anticipated Synchronous DDR4 (Double Data Rate 4) standard. That's DDR4, for those keeping count, which will offer "a range of innovative features designed to enable high speed operation and broad applicability in a variety of applications including servers, laptops, desktop PCs and consumer products." To facilitate comprehension... Read more...
