SMART Modular Shows Off 256 GB Gen-Z Memory Module

SMART Modular this month demonstrated one of the industry’s first prototypes of a EDSFF 3-inch DDR4 Gen-Z memory module. The ZMM supports advanced functionality enabled by the new interface and offers throughput akin to that offered by today’s DDR4-4000 memory modules.

SMART Modular’s 256 GB ZMM uses Samsung’s 32 Gb 4-high DDR4 DRAM devices as well as IntelliProp’s Gen-Z Mamba memory controller ASSP, which supports multiple access semantics, including byte and block addressable DRAM access, in-band configuration, and access key/region key memory isolation opcodes in a bid to simplify memory access needed to handle emerging data-centric workloads. The controller features 16 Gen-Z lanes with 25 Gbps PHY as well as 400 Gbps aggregate performance. The chip requires up to 20 W of power, so it needs proper cooling.

The Gen-Z module from SMART Module comes in SNIA’s 3-inch 4C SFF-TA-1008/9 form-factor, and offers a 30 GB/s bandwidth along with 400 ns deterministic access latency.

The 256 GB ZMM was demonstrated in rack servers designed by Dell and Hewlett Packard Enterprise specifically to test Gen-Z interconnection.

The showcase of a 256 GB Gen-Z ZMM by a well-known supplier of memory and storage solutions with two makers of servers indicates that the industry is getting ready for a roll-out of Gen-Z products in the future. What remains to be seen is when exactly SMART Modular and its partners will be ready with commercial Gen-Z modules and platforms.

Intel to Discontinue Itanium 9700 ‘Kittson’ Processor, the Last of the Itaniums

Image
Intel on Thursday notified its partners and customers that it would be discontinuing its Itanium 9700-series (codenamed Kittson) processors, the last Itanium chips on the market. Under their product discontinuance plan, Intel will cease shipments of Itanium CPUs in mid-2021, or a bit over two years from now. The impact to hardware vendors should be minimal – at this point HP Enterprise is the only company still buying the chips – but it nonetheless marks the end of an era for Intel and their interesting experiment into a non-x86 VLIW-style architecture. The current-generation octa and quad-core Itanium 9700-series processors were introduced by Intel in 2017, in the process becoming the final processors based on the IA-64 ISA. Kittson for its part was a clockspeed-enhanced version of the Itanium 9500-series ‘Poulson’ microarchitecture launched in 2012, and featured a 12 instructions per cycle issue width, 4-way Hyper-Threading, and multiple RAS capabilities not found on Xeon pr

Intel Axes 10nm CPU Based NUC

Image
Intel has notified its partners about plans to discontinue its only 10nm small form factor NUC in the market. The NUC, which went under the code name of Crimson Canyon, is/was Intel's only 10nm device in this market - it used Cannon Lake processors made on its 10 nm technology, and paired with AMD’s Radeon 540 graphics.  The fate of Intel’s Cannon Lake processors has been, to put it mildly, 'dead on arrival'. Delayed by over a year because of problems with 10 nm fabrication process, the CPUs suffered low yields and had design selections made that resulted in a non-functioning integrated GPU, as well as high power consumption: the Core i3-8121U processor at the heart of Intel's first generation 10nm ended up in a few China-only laptops ( which we reviewed ), and in a small number of Crimson Canyon NUC devices. Intel advises parties interested in its Crimson Canyon NUC SFF PCs to make their final orders by December 27, 2019, or return them by that date. The f

TeamGroup T-Force Xcalibur ARGB DDR4-4000 at Computex

Image
At Computex 2019, TeamGroup unveiled a couple of new products aimed at users looking for high-end components. One of these was its refreshed T-Force Xcalibur DDR4 memory now with addressable ARGB LEDs. During CES 2019, TeamGroup announced a set of ASRock Phantom Gaming branded Xcalibur RGB modules , fast forward to Computex 2019, TeamGroup had its new T-Force Xcalibur ARGB on display with the new ARGB heatsinks modelled over a high-end kit of DDR4-4000 Samsung B-Die based memory kit. The T-Force Xcalibur ARGB memory is very similar in design to the previous special edition Xcalibur RGB modules, but with new addressable RGB LEDs which seems to be the new market trend for gaming-focused brands. Each heatsink has a black aluminium finish with the Xcalibur and T-Force logos, with the 120 degrees angled lighting coming from the light bar at the top of the module which includes an Aztec inspired patterning. While TeamGroup only had a DDR4-4000 16 GB (2 x 8 GB) kit on displa
