Starting with Micron’s most recent earnings call The Memory Guy has been hearing memory executives and others use the word “Unprecedented” to describe today’s market collapse. Perhaps the strangest of these was an article in the Storage Newsletter that said that the current situation was “Unprecedented since 2008.” Given that “Unprecedented” means that nothing like this has ever happened before, that’s a pretty strange thing to say.
Being a numbers guy, I decided to see just how Continue reading “Today’s “Unprecedented” Collapses”
For almost two years there has been a lot of worry about DRAM spot prices. This post’s graphic plots the lowest weekly spot price per gigabyte for the cheapest DRAM, regardless of density, on a semi-logarithmic scale. (Remember that on a semi-logarithmic scale constant growth appears as a straight line.)
The downward-sloping red line on right side of the chart shows that DRAM prices have been sliding at a 45% annual rate since October 2014. This has a lot of people worried for the health of the industry.
What most fail to remember, though, is that DRAM spot prices hit their lowest point twice in 2011, at $2.40 in August, and then $2.20 in November. Today’s lowest DRAM spot prices have only recently dipped below the $2.52 point hit in October of 2014.
The black dotted line in the chart is intended to focus readers’ attention on DRAM costs, which decrease at a 30% average Continue reading “Putting DRAM Prices in Perspective”
Today Samsung announced that its chips are used exclusively to make up the 324-terabytes of DRAM in Germany’s new Leibniz Supercomputing Centre SuperMUC supercomputer.
Samsung’s release tells us that the SuperMUC, the most powerful supercomputer system in Europe, is an IBM System x iDataPlex dx360 M4 server built using over 18,000 Intel Xeon CPUs and over 80,000 4GB DRAM modules from Samsung. (Simple math makes this out to be 82,944 modules.)
That looks like a lot of silicon! Let’s see how much that might be.
A 4GB parity DRAM module would use nine 4Gb DRAM chips, which Samsung appears to Continue reading “Samsung DRAMs in Massive Leibniz SuperMUC”
