AWS is fed up with tech that wasn’t built for clouds because it has a big 'blast radius' when things go awry

Re: @Jim Mitchell

Most recent open compute specs are moving towards 12VDC or 48VDC busbars. All the sensible folks are doing it.

Efficiency for DC/DC is in the very high 90, and also very small, look at some of the Analog Devices DC/DC modules and you can do 100A @ 1.2V from something quarter the size of a matchbox with 12V input.

Busbars are pretty easy, substantial but still not a problem. I've seen 100kW per rack prototype systems with 3x 48V busbars. There are EU funded supercomputer research projects pushing that level of density.

Advanced Money-making Devices: AMD inks multibillion stock deal for FPGA specialist Xilinx

Re: Three way Horse Race

AMD gives Xilinx the ability to put ZEN CCUs in their high end designs as well. 4/8 Zen cores are already nice and modular and would crush the dual A72/73's they currently have if raw compute power was needed. Plus already made by TSMC so a Win Win all round.

Also, Xilinx has a very nice ARM license... Interesting to see Nvidia's take on that.

Welp, it is the season for silicon mega-mergers... AMD rumored to be in advanced talks to buy FPGA slinger Xilinx for $30bn+

They have history together...

Original Hyper transport systems had the option to put a Xilinx V5 in a socket i seem to recall (some German system I seem to recall) also, it does make sense providing they have a plan. Intel seem to have done nothing with their Altera IP worth noting.

Chiplet based EPYC CPUS could easily have one/two cpu chiplet replaced with pcie/cxl based FPGA chiplets... or maybe even FPGA type fabric inside Radeon chips to allow things like video decoding and ML to be accelerated and reconfigured on the fly.

Lets not forget Xilinx's experience in SERDES, IP that is needed to go to PCIe GEN 5/6 with PAM4 encoding at stupid data rates. They already have silicon running those rates easily.

Their Vitis software does compile OpenCL into FPGA logic reasonably well, well compared to the old C->VHDL stuff that used to exist years ago it's a massive leap.

I'd have suspect more of a Merger than full on buyout however. $30B is a lot of money given the market and history of AMD tripping itself up just when it look like it's on the up..

This investor blew nearly $300,000 on Intel shares the day before 7nm disaster reveal. Yup, she's suing

What a muppet! She was just hoping there would be good news and a 10% jump over night... Any fool would have known what was coming.

Bet she wishes she'd bought AMD shares when they are rock bottom at 2.50 USD....

Japanese probe to land asteroid rock sample in Australia on December 6th

Lets hope Michael Crichton was wrong then...

So I presume the return vessel will be taken straight to the Wildfire facility before all hell breaks loose?
