The backdoor is super useful for large enterprises, don't hope for much.

The issue I have is companies like Google and Puri.sm have asked Intel and AMD for a blank signed blob that completely disables ME but they have refused this. It would take them literally no time at all. This raises all sorts of red flags that something dodgy is going on. If you had the chance to make a supplier who creates millions of chromebooks happy, wouldn't you take every opportunity to help them, especially if…

Which is why someone with deep enough pockets and some help by the community (crowdfunding?) should invest in making open alternatives possible. Thousands of people have been laid off in the past by big silicon corporations, I refuse to believe there aren't 10 of those people in the world who caannot be hired to design an open platform. It doesn't have to be fast as modern processors; if it allows opening a webpage at acceptable speed or playing a video at 30fps 720p that is more than enough for most us, and more importantly would send a huge message. Many would of course disagree, mainly gamers who would sell their soul to the devil for a faster graphics card or other people who don't care about their privacy. Once the design is done, it comes the fab. Decades ago any company would have to set up its own but today there are fabless companies who design chips and fabs producing them for various customers, so it's just a matter of money. The goal isn't to create an alternative with respect to computing power, but rather in usage. The message is "we're not using your bugged shit to communicate among us or keep our data".

What do you mean by major apps? Do you have some reason to believe that apps will suddenly become embarrassingly parallel? Major apps often don't even take full advantage of SIMD instructions on the CPU. As soon as you need a context switch, branching, or fast memory access your GPU is crap. GPUs are only good at _very_ specific workloads.

I used to believe that, until I started to get into cryptocoin mining. There were algorithms that were specifically designed to be GPU resistant and they all were ported and saw significant gains. It was that experience that pushed me to learn how to program these devices. The tooling isn't good enough yet, but there is no question in my mind practically everything will run on a GPU like processor in the future. The…

Cryptocoin mining is embarrassingly parallel by its nature. You are trying lots of different inputs to a hash function, so you can always run an arbitrary number of them in parallel. There are various ways to reduce the GPU/FPGA/ASIC advantage, like requiring lots of RAM, but the task is still parallel if you have enough RAM. Something like a JavaScript JIT on the other hand is fundamentally hard to parallelize.

At this point real compute happens on the GPU. I think we'll see a shift to major apps being driven by GPGPU. The CPU's performance has started matter less and less.

Intel chips have a giant iGPU, that on certain models occupies near half the space. It can currently decode 4k Netflix. The technology is equally applicable to GPUs.

The video decoding is done by a hard block called Quick Sync. It's part of the iGPU, but is not using the regular GPU cores.

The statement was about the relative speed of a thousand dumb cores vs. a couple really good cores. Not about absolute speed.

The statement was stating an absolute. Algorithmic complaxity matters more than the speed of the computing hardware. Obviously, more power means you can compute more, but not everything.

That's a very uncharitable reading of what I wrote. The topic of the conversation was GPU performance vs CPU performance. Despite being less flexible, the sheer quantity of execution units more than makes up for it.

But no, I suppose its more likely I was really saying GPUs aren't bounded by the limits of the universe.

halvar flake (Google P0 security guy) talk a bit about it in the last Black Hat Asia : https://www.youtube.com/watch?v=JCa3PBt4r-k . Basically he says that even Google is puny (in terms of production units) in front of Intel or Samsung, and cannot ask for custom firmwares. Hardware security is currently a shit show because of global monopolies/"oligopolies".

If Google is tiny in Intel's eyes, who isn't? They operate a top 3 cloud service and have enormous internal data centers as well.

Companies that act as OEMs for enterprises most likely have a larger footprint of Intel installs than Google. Any single companies usage of a product is dwarfed by how much effective installs a large OEM might have.

Maybe if Lenovo, Toshiba, Acer, Dell, etc all asked Intel to provide said blobs (and the threat was tangible) then they would probably reconsider.

Gains in instructions-per-clock start to flatten out. And that's where the gains were coming from in the last years. Some time ago a paper was posted here that showed how even if you have an infinite amount of transistors, you will still be limited in the range of 3-10 instructions-per-clock for typical programs. Clock speeds seem to have leveled and IPC will only see another gain of 50-100%. Single threaded performa…

GPUs: http://michaelgalloy.com/2013/06/11/cpu-vs-gpu-performance.h... http://www.anandtech.com/show/7603/mac-pro-review-late-2013/... This is behind much of the interest in machine learning these days. Deep learning provides a way to approximate any computable function as the composition of matrix operations with non-linearities. It does this at the cost of requiring many, many times the computing power. But much of…

I don't think GPUs are a particularly good solution for these, they aren't the future and won't be around for mass-deployment that much longer.

The Osborne effect: https://en.wikipedia.org/wiki/Osborne_effect Although it has been deliberately deployed many times now, as you note one example of.

And people keep falling for it See:Itanium Never compare an existing product to one that is not yet being sold. Never

Itanium was such a strange ... event. A complete outlier, it is even from today's perspective not easy to see why it happened.

Well actually I think it's more a case of "increase in performance is becoming harder and harder, the technology leader (Intel) is slowly becoming stuck and the competition (AMD) is catching up". Everybody will be more or less at the same level as it requires huge investments to only get a marginal advantage. Apart from games, I would not be that afraid to install recent pieces of software (browser, office suit, os)…

Memory and storage. Still big gains to be had there. Imagine if your whole hard drive was RAM speed.

Also more specialised cores e.g. DSP, and customisable hardware i.e. FPGA.

Anyone else get redirected to malware?

And people get mad on here when I say that I use an adblocker. Until the ad industry gets its shit together, I will continue to do so, as not blocking ads is negligent from a security perspective. This is a terrible state of affairs.

I wonder if this one will come with free backdoors and spyware installed, thanks to the wonderful Intel Management Engine (Intel ME) backdoor. [1][2][3] Intel (and AMT) keep pushing more and more proprietary code that can not be read, changed or removed. No one knows exactly what it does and it has built in screen and key recording. It's my advice and the advice of privacy advocates that no one should purchase or use…

> no one should purchase or use any processor made by Intel or AMD until they address these serious issues. so go back to stone age by stop using all PCs/Servers? nice troll.

In addition to MiniFree, there's the Talos II[1] which is an entirely free motherboard and CPU (based on IBM's POWER9). It's a very modern CPU specification, and is also fairly powerful. Currently pre-orders are open. They are a bit pricey (~$2k for a fully prebuilt machine), but if you feel that you want a more powerful CPU that is an option. They also have server offerings.
