"A new startup out of MIT emerged from stealth mode today to announce that they're shipping a 64-core processor for the embedded market. The company, called Tilera, was founded by Dr. Anat Agarwal, the MIT professor behind the famous and venerable Raw project on which Tilera's first product, the TILE64 processor, is based. Tilera's director of marketing, Bob Dowd, told Ars that TILE64 represents a "sea change in the computing industry", and the company's CEO isn't shy about pitching the chip as the "first significant new chip architectural development in a decade". So let's take an initial look at what was announced about TILE64 today, with further information to follow as it becomes available."

The Core 2 is actually less RISC-y internally than the P4. The P4 is internally a pure u-op design. The Core 2 caries fused u-ops (eg: mem-op instructions) through much of the frontend of the core.
As for PPC, ARM, and MIPS, one of those three does not belong. MIPS is a great instruction set. PowerPC is poo.

Oh, ARM is fine. It's PPC that doesn't belong. I just don't like the basic design (too many weird instructions, no separate 32-bit and 64-bit operations, etc).
MIPS is my favorite, but x86-64 comes in a close second. It's so much better than people give it credit for. It's actually quite orthogonal in its addressing and operand modes. You get 8-bit, 32-bit, and 64-bit registers, along with 8-bit, 32-bit, and 64-bit operations. You get 8-bit and 32-bit immediates and displacements, instead of the oddly-sized immediates and displacements you usually get in RISC. Instructions that write to fixed registers and two-operand instructions suck a bit, but you can deal with both quite easily in the register allocator.

Not even close. Intel has been converting from x86 to internal micro operations since the original Pentium more than 10 years ago.
PPC, ARM and RISC aren't in any way more efficient than x86. The ISA is just like and API and in no way reflects efficiency. A lot of issues with X86 are easily fixed by clever hardware design.
Yeah it's not as elegant as PPC or MIPS but it's also a lot older.

"Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). Unlike last generation, you don't need to be some sort of Jedi to extract the PS4's potential here. The Xbox One and PS4 architectures are quite similar, Sony just has more hardware under the hood. Weâll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that itâs usually the lowest common denominator that determines the bulk of the experience across all platforms. On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques." AnandTech does its usual in-depth thing.

"The Verge has learned that HTC's Chief Product Officer, Kouji Kodera, left the company last week. Kodera was responsible for HTC's overall product strategy, which makes the departure especially notable on the heels of the global launch of the make-or-break One. It's not just Kodera. In the past three-odd months, HTC has lost a number of employees in rapid succession." I really hope HTC pulls it together.

"It is with huge pleasure that the Debian GNU/Hurd team announces the release of Debian GNU/Hurd 2013. This is a snapshot of Debian 'sid' at the time of the Debian 'wheezy' release (May 2013), so it is mostly based on the same sources. It is not an official Debian release, but it is an official Debian GNU/Hurd port release." Important note: 75% of Debian packages are supported bu Debian GNU/Hurd. Impressive.

"The first killer app was VisiCalc. This early spreadsheet turned the Apple II from a hobbyist toy to a business computer. VisiCalc came with room for improvement, though. In addition, a new architecture and operating system, the Intel-based IBM PC and MS-DOS, also needed a spreadsheet to be taken seriously. That spreadsheet, released in early 1983, would be Lotus 1-2-3, and it would change the world. It became the PC's killer app, and the world would never be the same. On May 14, IBM quietly announced the end of the road for 1-2-3, along with Lotus Organizer and the Lotus SmartSuite office suite. Lotus 1-2-3's day is done." Impressive 30 year run.

"There's a disconnect between how Apple CEO Tim Cook sees his company's tax strategies and how some members of the US Senate view it. That became clearer than ever today after Cook and two other Apple executives testified before Congress, explaining why they're holding most of their international income in Irish subsidiaries like Apple Operations International, which declare no tax residency anywhere in the world. AOI hasn't filed a tax return anywhere in the world for the last five years, yet it earned $30 billion in income from 2009 to 2012, according to a Senate report released yesterday." Just because something is legal, doesn't mean it's just. Apple, Google, Microsoft, and many more - these companies might not be breaking any laws, but it's obvious to anyone that what they are doing is scummy.

The new WebKit Opera for Android has been released. "Opera 14 for Android is built on top of Chromium 26, with a total overhaul of the UI in native code, making it fit well with the latest Android design guidelines. Go get the build from Google Play or point your browser to m.opera.com, and give it a spin!"

The Verge pointed me to a blog post by Leap Motion - which reveals how their Kinect-like motion control works with Windows 8. "From the second you plug in your Leap Motion Controller, you'll be able to browse the web and interact with your computer just by moving your hands and fingers in the air. With Leap Motion technology and Windows, you can do everything that's possible with multi-touch inputs - without actually touching anything. This also means that existing applications in Windows 7 and 8 will respond to your natural hand and finger movements. Soon, we'll show you how Leap Motion will work with Mac OS X." Quite cool.

PocketNow interviews Marc Dillon, and there's an interesting note about why Jolla is keeping the display properties under wraps: "We're leaving some of those details out because we do understand that there are a lot of really big players in the market and they tend to take certain components in the market and dominate them. We created the ability to actually be able to run Sailfish on multiple hardware displays and be able to swap components, so this is part of the demand and supply planning phase. We are committed to this industrial design which is a 4.5-inch display, an 8 megapixel camera on the back and a front-facing camera at the front, and the exact specs of the display we'll provide when we're close to delivery." Something you rarely hear anything about.

"This is my NeXTstation Turbo Color booting the Mac System 7.1 Operating System using a hardware add-on called 'Daydream'. The Daydream has a Mac ROM and a few custom ICs in it and hooked up to the NeXTs DSP port. Turns your NeXT into a full fledged 68k powered Mac." So cool.

If anything x86 isn't exactly a great architecture, just "good enough". If you've tried programming it, you know that even 6502 is more elegant.
PPC, ARM, MIPS &c are all excellent architectures which can be programmed highly, highly efficiently by someone who knows what they're doing and isn't clouded by doing things solely the x86 way.
Oh, and modern CPUs like the Core Duo emulate x86 macros down to more a more RISC-like central set. This is how Intel managed to make the jump from the hot, high-power P4's to relatively cooler and lower power Dual Core chips.
