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...
