Otellini unveils Nehalem
- Thread starter Teaf
- Start date
This chip is the culmination of two decades work by Intel. It brings together ideas from its x86, NetBurst and Itanium architectures and puts them all under one roof. It is going to be excellent. It will be my next upgrade 
I'm kinda debating over the whole octo-core thing myself. I mean quads are barely getting used at the moment in the mainstream world, and probably are still not going to be heavily used when Nehalem appears, and then nothing will use 8 cores pretty much so I'm wondering if it's going to work out well. Sure the chip speed will increase due to better architecture and so forth, but I guess I'm just suprised it turned into octo-core rather than much higher frequency speeds (4Ghz and above).
So am i flibby, but i believe we're in a transitional phase and we're gonna end up with crazy fast computers no matter what. Multicore programs will be more and more widespread, Windows will be written to do it and so will most other commonly used programs, Vista is already there i believe, and Linux has been for a long time.
Plus, we're getting to the higher clock speeds once more, which is great.
But what people need to remember is IPC, simply, the effectivity of processors are getting so much better. Why do the C2Ds rock besides Overclockability? The fact that they just have so much more work getting done than an AM2 puts it out on top, every single time, even against far higher clock speeds. Penryn will improve IPC 5-10% in some cases, and while not a big improvement, hopefully Penryn will get quadcore implemented properly, with higher clock speeds for less money.
Nehalem is something else entirely, finally an integrated memory controller to make full use of the crazy amount of bandwidth, more scalability, dynamic cores, and of course a lot more architectural improvements will result in IPC going up even more, again along with both core count and clock speeds.
No matter what, whether using 1 core or 500 cores in the future, programs will be quicker than ever, simply because the engineers are getting more and more experienced, and can continually improve on the bus, the IPC, memory technologies, etc.

Right I'm skipping Penryn, straight to this in early 09

Forget about the dual, quad, octo core thing, providing software is created with multi-threading in mind the number of core's/threads available wont make any difference, they will scale as expected.
While this may not appear straight away for gaming, modern games are made with multi-threading in mind so should scale to higher core numbers accordingly.

Think about it, a couple of years ago, nobody saw the need for dual cores, but now they're the 'de facto' for buying new CPUs because software engineers are catching up. Of course you're not gonna get old apps to run on insane amounts of cores, but newer applications are scaling like everyone would expect them to. This makes sense for everyone. The processor manufacturer has a relatively easy way of adding performance, the software designer gets literally workload in powers extra, and we reap the benefits.
No idea why people are so hostile to multi-core.

I wouldn't call it hostile or I am not hostile towards them at least, but I think it's mainly because dual core was a couple of years ago, whilst octo-core is 1 year away and quad is now and we still yet to see quad's being utilised properly in games and applications. Talrinys does make an excellent point however and a good read, thanks for the info
Remember, its not just the 'Desktop' market that intel want to get the crown on. AMD are still very good performance on the 8+ core server market. Baracalono quads, on a quad cpu motherboard gives you 16 cores to play with, and thats where AMD's integrated memory controllers keeps AMD powered servers very good at running a lot of tasks at once.
But a Dual socket, Nehelem, with 16cores, and 32 threads... Intel are actually starting to catch up with Sun's Niagra (which is 8 cores/32 threads) although Sun have Niagra 2 now which is 64 threads!.
Nehelem is just what the server market needs, that said, it should also make a nice desktop processor. And as software developers get more used to writing threadsafe code, then cpu's will scale well as cores increase.

Just octo-core I think? Although they are in two different flavours of process it seems, 45nm and later on 32nm.
I am not too enthusiastic about the return of hyperthreading, when you have 8 cores it seems a little redundant.
You have got to love the business talk though "modular" "dynamic".
With them promising 8 cores and single-threaded speed improvements I will get one unless AMD bring something better out first.

Fantastic news really, Octuple Core processor... a version of HyperThreading is returning bringing a total of 16 independent threads
yeah thats brilliant huh, considering most stuff still doesn't make use of two cores, never mind 8 cores capable of running 16 threads, it'll be brilliant benchmarker, encoding chip, workstation stuff like studio max and maya, etc, but i don't see it bringing any improvement to gaming, just gonna end up with six wasted cores...
Bit of extra info for interested parties.
So looks like Nehalem will be available in 2 core (4 thread), 4 core (8 thread) and 8 core (16 thread). That's kinda nice, I'd imagine the 2 / 4 core stuff is going to be quite cheap to the 8 core stuff and we might see something like the E2140/2160 now but in 4 core style.
Oh also, Penryn will start at 2.55 Ghz seemingly for the chips and go up to 3.15 Ghz. Over the space of 2008, they will reach 4Ghz STOCK speeds, and Nehalem is apparantly STARTING at 4Ghz... 4Ghz - 5Ghz stock 8 core / 16 thread cpus with this arch. and technology will be a sight to behold!

Idd, considering skipping Penryn altogether and wait for this....
