Intel Details Nehalem CPU and Larrabee GPU
Vigile writes "Intel previewed the information set to be released at IDF next month including details on a wide array of technology for server, workstation, desktop and graphics chips. The upcoming Tukwila chip will replace the current Itanium lineup with about twice the performance at a cost of 2 billion transistors and Dunnington is a hexa-core processor using existing Core 2 architecture. Details of Nehalem, Intel's next desktop CPU core that includes an integrated memory controller, show a return of HyperThreading-like SMT, a new SSE 4.2 extension and modular design that features optional integrated graphics on the CPU as well. Could Intel beat AMD in its own "Fusion" plans? Finally, Larrabee, the GPU technology Intel is building, was verified to support OpenGL and DirectX upon release and Intel provided information on a new extension called Advanced Vector Extension (AVX) for SSE that would improve graphics performance on the many-core architecture."

They are code names, not product names.
Intel has a rich collection of silly code names.
Evil people are out to get you.
You can't trademark numbers. When AMD started releasing "x86" numbered processors, Intel filed suit and lost. The judge stated that you can't trademark numbers. It's such an old case, this is what I found in the last 10 minutes regarding Intel and trademarking numbers.
I'm tired and too lazy to find the actual lawsuit.
I prefer Flambe as apposed flamebait.
I vote AMD hit back with "Orgo" and "Ftoomsh"
"Be light, stinging, insolent and melancholy"
Heck, I remember when "Itanium" came out and people laughed...
But before they laughed, I remember a bunch of companies folded up their project tents (sun, mips, the remains of dec/alpha). I'm not so sure companies will do the same this time around... Not saying this time Intel doesn't have their ducks in a row, but certainly, the past is no indication of the future...
I vote for Skookumchuck.
I judt got a nre Kinesis keybiartf so please excusr ant egregiou typos.
Buckle your ROFL belt, we're in for some LOLs.
So, this Larrabee, will it be another example of integrated graphics that "supports" all the standards while being too slow to be useful in any practical situation, even basic desktop acceleration (Composite / Aero)? If so, I've gotta wonder why they even bother rather than saving some cash and just making a solid 2D accelerator that would be for all intents and purposes functionally identical.
Most of Intel's codenames are names of real places.
First off, new integrated Intel chipsets do just find for desktop acceleration. One of our professors got a laptop with an X3000 chip and it does quite well in Vista. All the eye candy works and is plenty snappy.
However, this will be much faster since it fixes a major problem with integrated graphics: Shared RAM. All integrated Intel chipsets nab system RAM to work. Makes sense, this keeps costs down and that is the whole idea behind them. The problem is it is slow. System RAM is much slower than video RAM. As an example, high end systems might have a theoretical max RAM bandwidth of 10GB/sec if they have the latest DDR3. In reality, it is going to be more along the lines of 5GB/sec in systems that have integrated graphics. A high end graphics card can have 10 TIMES that. The 8800 Ultra has a theoretical bandwidth over 100GB/sec.
Well, in addition to the RAM not being as fast, the GPU has to fight with the CPU for access to it. All in all, it means that RAM access is just not fast for the GPU. That is a major limiting factor in modern graphics. Pushing all those pixels with multiple passes of textures takes some serious memory bandwidth. No problem for a discrete card, of course, it'll have it's own RAM just like any other.
In addition to that, it looks like they are putting some real beefy processing power on this thing.
As such I expect this will perform quite well. Will it do as good as the offerings from nVidia or ATi? Who knows? But this clearly isn't just an integrated chip on a board.

It took them a while to get that it was a joke.

Because power generally increases at a rate of frequency^3 (that's cubed). Adding more cores generally increases power linearly.
For example. Let's start with a single-core Core 2 @ 2GHz. Let's say it uses 10 W (not sure what the actual number is).
Running it at twice the frequency results in a (2^3) = 8X power increase. So, we can either have a single-core 4 GHz Core 2 at 80W, or we can have a quad-core 2GHz Core 2 at 40W. Which one makes more sense?

1) We've hit the "Power Wall", power is expensive, but transistors are "free". That is, we can put more transistors on a chip than we have the power to turn on.
2) We also have hit the "Memory Wall", modern microprocessors can take 200 clocks to access DRAM, but even floating-point multiplies may take only four clock cycles.
3) Because of this, processor performance gain has slowed dramatically. In 2006, performance is a factor of three below the traditional doubling every 18 months that occurred between 1986 and 2002.
To understand where we are, and why the only way to go now is parallelism versus clock speed increase, see The Landscape of Parallel Computing ReseView from Berkeley.
I say this, as an admitted AMD fanboy, and in hopes that they can make a comeback, to once again force intel into a frenzy of research and development. I Can't help but imagine that AMD exec's are saying something along the lines of Isoroku Yamamota's famous WWII post pearl harbor quote, "I fear that all we have done is to awaken a sleeping giant." It's all gravy for consumers so one can't help to be happy at the current developments. However to ensure future happiness for consumers, one must also hope for an AMD Comeback.

How long until they release a chip named after Intercourse,PA,
Or my favourite, Wankers Corner,OR
AMD will join the fun and look to France for inspirational place names, such as Condom, Tampon and Herpes
Not to be outdone, poor old Amiga Inc finally release a new computer named after the village of Shittington,in the UK,with an update scheduled for 2025 named after Mount Buggery in Australia.
They weren't even used in the Arab world until modern times -
http://en.wikipedia.org/wiki/History_of_the_Hindu-Arabic_numeral_system In the Arab world - until modern times - the Arabic numeral system was used only by mathematicians. Muslim scientists used the Babylonian numeral system, and merchants used the Abjad numerals. It was not until Fibonacci that the Arabic numeral system was used by a large population.
