AMD Announcement: ARMv8 Opterons In 2014

Is this not a war on two fronts? One of these days, Samsung will ship their own ARMv8 uarch implementation and with their ownership of a fab, become to ARM what Intel is to x86. And for all the talk of fabrics and interconnects, the Facebook rep at the press event doesn't even care: Strangely...

AMD Announcement: ARMv8 Opterons In 2014

I have never heard of an x86 exclusivity agreement with GF at any process node. I think there exists a secret agreement that grants x86 exclusivity in perpetuity, in which case expect to see more payments for unheard of 20 nm and 14 nm exclusivity agreements going forward.

R Read - "Our semi-custom APUs" = Xbox 720 + PS4?

What is the last possible moment for MS to finalize their SOC specs, and not pay an arm and a leg to rush it through verification, physical design, tapeout, manufacturing, bring-up, driver development, and getting kits to developers so that games are polished enough for launch?

I hear that TSMC has good yields

AMD Announcement: ARMv8 Opterons In 2014

Some work is saved if certain blocks are hard macros, so the transistor layout is fixed for a certain process. Graphics and CPU cores would probably fall into this category - take previous claims of these things being "synthesizable" with a grain of salt, because if they're smart about it...

Settle down everyone at least AMD is trying.

From what I have seen, the clock network accounts for at least half of the total power consumed in a block. Much of that power is consumed by flip-flops in pipeline stages. Doing more work per cycle means less pipeline stages, means less flops, means less clock power consumption. Of course if...

ARM profits up 22%. Maybe the tech economy is doing well after all.

Intel did make Atom available to TSMC. It failed miserably. They have also made tentative foundry-ish moves: Atom + Altera FPGA, manufacturing for Netronome, Tabula, and Achronix. If Tabula or Achronix proves particularly successful, I could see Intel making a move to acquire it/them and expand...

I meant to say that, if both designs target the same process, then they will inevitably compete with each other for fab capacity, and delaying one so that both need to ramp production in the same time frame will only exacerbate the problem.

This isn't a get out of jail free card: "GLOBALFOUNDRIES waived the exclusivity arrangement for AMD to manufacture certain 28nm APU products at GLOBALFOUNDRIES for a specified period." They don't say which APU's, and they don't say for how long. It could very well be that whatever gets fab'd...

Aren't there keyboard synth mixer boards that are better suited to audio work?

Recent console generations have come in under 10 years. Looking at release dates for the PlayStation, Sony has aimed for about 6 to 7 years between releases. Nintendo has been about 5 to 6 years, and Microsoft is a bit all over the map with the first Xbox in 2001, the 360 in 2005, and this next...

AM3+ upgrade- worth it?

In the worse case, about $100 gets you two more cores. You could then wait out the Steamroller launch and pick up those parts on sale if they seem like a good upgrade.

CPU for video encoding

I don't think the HandBrake FAQ is recommending that you get a Mac. If anything, it's saying that certain features offered by a Mac are not helpful and so HandBrake's developers see no point in using them. CPU encoding is still the way to go. The HandBrake FAQ's comments on OpenCL illustrate...

Is TRIM support now a basic OS feature?

An SSD is treated by WinXP like any other spinning hard drive. TRIM speeds up physical block erasure, but the SSD's garbage collector will get to them eventually. Creating and deleting large numbers of files in a short span of time could swamp the garbage collector and cause performance to decrease.

Performance vs. Power usage (desktop GPUs)

I have this weird notion that lower TDP meant longer lifespan. Replacing things when I want to is less stressful than replacing things when I have to.
