Re: Intel-Micron XPoint

This is memristor technology. Memristors are two terminal devices. Current flowing one direction changes the bit to high resistance, current flowing the opposite direction changes the state to low resistance. The secret sauce here is how to keep the [more]

Re: 7 nm test chips

It seems like Intel doesn't show off the early things like this - either they're often behind or they are OK with not showing off.

Even though it may look like a race from outside the industry, the progress towards ever smaller [more]

Re: AMD slammed 13% on warning

AnandTech is reporting that AMD is now confirming that they have moved several of their 20nm designs to a “leading-edge FinFET node,”. This is most likely GPUs. AMD had been planning to make a jump to 20nm, then to 16/14nm [more]

Re: AMD slammed 13% on warning

sorry, just to clarify (I've lost track): did we know about this shift in process for new products? and just didn't take into account the costs associated with it?

No. Yes. It's complicated. Take your pick.

Not everyone plays Crysis

If you try reading through the benchmarks for AMD's 300 series, you may wonder why AMD boosted the memory size for many of the lower powered CPUs. You may also wonder why AMD came out with the Fury with only 4 Gig of graphics memory, while [more]

Re: Fury X review list

Looks like there is room for improvement in the drivers.

Actually there are two improvements needed, which will not come from AMD. The first, is DirectX 12 and games designed to use it, or designed for Vulkan or OpenGL 4.5 all three [more]

Re: AMD Split Up?

I would more state it as investors are nervous (with good reason) and AMD in effect put any profit for this year off into the third quarter. So they need to have something to talk about a month from now with the April to June results.

News on the EUV front...

AFAIK, EUV is not being used in production anywhere. Well, it depends on how you define production. EUV can be, and again AFAIK is being used to manufacture masks, but double and quad exposure techniques are better suited for 23-32 nm and 13-17 nm [more]

Meaning what, Seattle is worth pushing out there for more than just an initial development target, or they're just going to kill time until Zen is out and they can focus on K12?

It probably means that some major OEM wants to build a [more]

Re: Financial Analysts Day

New HBM GPUs coming this quarter (yes, 2Q2015)

Yes apparently during Computex, the first week of June.

Finally. (First week of June.) What apparently happened was that AMD had planned a 285X (Tonga) product with 3 Gig [more]
