2018: A banner year

Intel has a long history of generating tremendous amounts of revenue and income. This latest quarter is no exception. Intel has announced record Q1 revenues for this year and they look to continue that trend throughout 2018. AMD released their very positive results yesterday, but their finances are dwarfed by what Intel has brought to market. The company had revenue of $16.1 billion with a net income of $4.5 billion. Compare this to AMD’s $1.625B revenue and $81M net income we see that the massive gulf between these two companies will not be bridged anytime soon with either Intel falling or AMD gaining.

Intel has put its money to good use with a wide variety of products that stretch between the PC market and datacenters. While their low power and ultra-mobile strategies have been scaled back and cancelled in some cases, their core markets are unaffected and they continue to make money hand over fist. The company has always been fundamentally sound in terms of finances and they do not typically spend money recklessly. They continue to feature market leading IPC with their product lines and can address multiple markets with the x86 products they have.

Jim Keller Leaves Tesla for Intel

Update: The official Intel announcement can be found here.

For anyone that follows the twists and turns of the semiconductor world, the name “Jim Keller” is approaching legendary proportions. He was a driving force in AMD’s K7 and K8 development, he moved on to PA Semi which was acquired by Apple to produce their class leading SoC’s for the iPhone, and then went back to AMD to become lead architect of the Zen architecture which powers the latest Ryzen CPUs from AMD. He then moved on to Tesla to be in charge of chip development for their autonomous driving program.

jk_intel_01.png

Very little has been heard from Jim Keller while he was at Tesla. The assumption was that he continued to do his job there and worked hard to innovate the potential chip designs that would power next generation Tesla vehicles to have fully autonomous driving capabilities. While that program has been in its infancy, we have not heard of custom chips being utilized by Tesla in the latest cars.

Now we have confirmation that Jim has left Tesla and has in fact been hired by Intel. Some months back Raja Koduri was hired by Intel to be in charge of all core development with a special interest in GPUs. It looks as if Raja has persuaded Jim to hop on board and help with what appears to be a stagnant core development team on the CPU side.

Intel has a history of “not invented here” mentality that has in previous years caused massive problems with the company. The reliance on the Pentium IV and its further development allowed their primary competitor to sneak up on them and shake up the marketplace. It took a design group out of Israel to set Intel onto a better path with the Banias/Conroe architectures which then lead to the Core architecture that we have seen iterated upon for the past decade.

The company has stagnated again. While the current Core architecture is faster in terms of IPC than Zen, it is a company that has not pursued innovation in a manner that has kept its competitor at bay. Jim Keller went back to AMD and architected what would become the Zen family of chips. In the space of those years he was there, he took the best technology AMD had to offer and built from the ground up a new architecture that could compete against Intel for a fraction of the R&D costs that the semiconductor giant typically spends. Intel stands to lose some significant marketshare in mobile, desktop, and server with the latest offerings from AMD. Combine this with the issues that the manufacturing group have run into with their development of the 10nm process, Intel seems to finally realize that design is really what matters when manufacturing issues hit. We can remember back in the Athlon 64/Pentium 4 days when AMD was 18 months behind on process technology, but still held a power/performance edge over Intel. While manufacturing can give a large advantage to any chip, a great design will not have to rely as heavily on cutting edge process tech to be competitive. Intel should hold all the keys to creating a truly overpowering series of products for their primary markets, but AMD has shown up with the plucky architecture that could cause some serious perturbations throughout the mobile, desktop, and server markets.

It seems that Raja is “getting the gang back together” to revamp the design culture at Intel to more adequately deal with threats to their CPU dominance across the board. They also are probably looking more closely at the ultra-mobile market that ARM has dominated for the past decade. Previous Atom designs have not come close to the efficiency needed to address those markets, but perhaps with a change of leadership and architects we can see Intel successfully address this very important area with high performance/high efficiency chips that we honestly expect them to be able to design.

Jim Keller to Intel looks to be a transformational move. Not just because of his expertise in architecture, but also a shift in how Intel goes about its daily business. Bringing this kind of expertise into the company is a watershed moment that moves away from the “not invented here” mentality that seems to dictate decisions at the company when they are not facing serious competition. We will see what kind of power Raja and Jim can leverage in changing the culture of the company. What cannot be denied is that Intel has frittered away its advantages in core design by not implementing aggressive product and feature changes for the past decade to insure its dominance in the CPU world. Compound this situation with the manufacturing woes at 10nm and we can see that Intel needed a shakeup.

Consider Intel shook.

The Experiment...

Introduction

OK, call me crazy (you wouldn’t be the first) but this is something I’ve wanted to try for years, and I bet I’m not the only one. Each time a new power supply comes across the lab bench with ever increasing output capacities, I find myself thinking, “I could weld with this beast.” Well the AX1600i pushed me over the edge and I decided to give it a go; what could possibly go wrong?

2-Side-view.jpg

133.3 Amps on the +12V outputs!

The Corsair AX1600i Digital power supply can deliver up to 133 Amps on the combined +12V rails, more than enough amperage for welding. There are dozens of PC power supplies on the market today that can deliver 100 Amps or more on the +12V output, but the AX1600i has another feature that might help make this project a success, the ability to manually set current limits on the +12V outputs. Thanks to the fact that the AX1600i is a digital power supply that allows manually setting the current limits on the +12V outputs via the Corsair Link data acquisition and control software, I might be able to add the ability to select a desired amperage to weld with. Yes!

Just because the AX1600i “can” deliver 133A doesn’t mean I want that much current available for welding. I typically only use that much power when I’m welding heavy steel pieces using ¼” rod. For this experiment I would like to be able to start out at a lot lower amperage, and I’m hoping the Corsair Link software will provide that ability.

3-Setup.jpg

Stick Welding with a PC Power Supply!

My first thought was to try to adapt a TIG (Tungsten Inert Gas) welder for use with the AX1600i. I figured using a TIG torch (Tungsten electrode shrouded with Argon gas instead of a flux coated rod) might give better control especially at the lower voltage and currents where I plan to start testing. TIG welders are commonly used to weld small stainless steel parts and sheet metal. But then I remembered the TIG welder power supply has a high voltage pulse built-in to initiate the plasma arc. Without that extra kick-start, it might be difficult to strike an arc without damaging the fine pointed tip of the Tungsten electrode. So I decided to just go with a conventional stick welding setup. The fact that PC power supplies put out DC voltage will be an advantage over the more common AC buzz-box arc welders for better stability and producing higher quality welds.

Modifications

Obviously, trying to convert a PC power supply into an arc welding power supply will require a few modifications. Here is a quick list of the main challenges I think we will have to overcome.

•    Higher capacity fan for better cooling
•    Terminate all the PSU’s +12V cables into welding leads
•    Disable the Short Circuit protection feature
•    Implement selecting the desired current output
•    Strike and maintain a stable arc with only 12 volts
