Amid the ongoing Meltdown fiasco, Intel has only one way to go in the data center... down. Intel may be forced to offer discounts or rebates to prevent customers from eventually moving to AMD x86 chips (such as Epyc) or even ARM chips:
Intel chips back 98% of data center operations, according to industry consultancy IDC. [...] Microsoft said on Tuesday the patches necessary to secure the threats could have a significant performance impact on servers.
[...] For Gleb Budman's company, San Mateo-based online storage firm Backblaze, building with ARM chips would not be difficult. "If ARM provides enough computing power at lower cost or lower power than x86, it would be a strong incentive for us to switch," said Budman. "If the fix for x86 results in a dramatically decreased level of performance, that might increasingly push in favor of switching to ARM."
Infinitely Virtual, a Los Angeles-based cloud computing vendor, is counting on Intel to replace equipment or offer a rebate to make up for the loss in computing power, Chief Executive Adam Stern said in an interview. "If Intel doesn't step up and do something to make this right then we're going to have to punish them in the marketplace by not purchasing their products," said Stern, whose company relies exclusively on Intel processors.
[...] Both Qualcomm and Cavium are developing ARM chips aimed at data centers. Cavium said it aimed to rival the performance of Intel chips for applications like databases and the content-delivery networks that help speed things like how fast online videos load.

Arthur T Knackerbracket has found the following story:
Qualcomm has confirmed its processors have the same security vulnerabilities disclosed this week in Intel, Arm and AMD CPU cores this week.
The California tech giant picked the favored Friday US West Coast afternoon "news dump" slot to admit at least some of its billions of Arm-compatible Snapdragon system-on-chips and newly released Centriq server-grade processors are subject to the Meltdown and/or Spectre data-theft bugs.
[...] Qualcomm declined to comment further on precisely which of the three CVE-listed vulnerabilities its chips were subject to, or give any details on which of its CPU models may be vulnerable. The paper describing the Spectre data-snooping attacks mentions that Qualcomm's CPUs are affected, while the Meltdown paper doesn't conclude either way.
[...] Apple, which too bases its iOS A-series processors on Arm's instruction set, said earlier this week that its mobile CPUs were vulnerable to Spectre and Meltdown – patches are available or incoming for iOS. The iGiant's Intel-based Macs also need the latest macOS, version 10.13.2 or greater, to kill off Meltdown attacks.
Cray is adding an AMD processor option to its CS500 line of clustered supercomputers.
The CS500 supports more than 11,000 nodes which can use Intel Xeon SP CPUs, optionally accelerated by Nvidia Tesla GPUs or Intel Phi co-processors. Intel Stratix FPGA acceleration is also supported.
There can be up to 72 nodes in a rack, interconnected by EDR/FDR InfiniBand or Intel's OmniPath fabric.
Cray has now added an AMD Epyc 7000 option to the CPU mix:
- Systems provide four dual-socket nodes in a 2U chassis
- Each node supports two PCIe 3.0 x 16 slots (200Gb network capability) and HDD/SSD options
- Epyc 7000 processors support up to 32 cores and eight DDR4 memory channels per socket
Top-of-the-line Epyc chips have 32 cores and 64 threads. An upcoming generation of 7nm Epyc chips is rumored to have up to 48 or 64 cores, using 6 or 8 cores per Core Complex (CCX) instead of the current 4.
