The CPU itself doesn't have anything to do with the amount of RAM supported (unless the memory controller is on the CPU).
With current Atoms, the memory controller is on the northbridge. Nvidia Ion chipset, for example, let's you even use dual channel of DDR3 RAM. So it's currently possible to use more than 1GB of RAM with Atoms (even with the Intel chipset, I think). I don't really trust Fudzilla (your source). #intelatom

I don't think the problem was ever hardware-induced. Lenovo currently sells their S12 with 2 and 3 GB configurations with a vanilla N270 Atom CPU.

I believe that the problem really was ARTIFICIAL, with Intel not allowing manufacturers to include more RAM on these netbooks -- which sucks big time. #intelatom

Although Intel doesn't market chips according to their codenames, the individual chip gets a model number that gives you an idea of how it compares, spec-wise (clock speed, cache size, etc.), to other chips in the same group.

That's not entirely true. An Intel i7 870 (and 860 for that matter) are going to be a hell of a lot faster than an i7 920. They are different core types and that idiom holds true for each core, but the general public will see i7 920 vs. i7 870 and mistakenly think the 920 is faster.

Thanks for the previous article, Giz. I read through it when it came out, but I was just looking for it.

i7 sounds good. Anyone have any idea of the difficulty level to transfer an Adobe CS3 license to a new computer?

Thanks #newimacs

@J2M3: Neutral. Nehalem was already used in the Pros, so the support was there. I'm not big on hackintoshing, but there may be some particulars to the P55 motherboards that it helps because of the new i5/i7's being used. #newimacs

One should also note that the high end 27" has the 2.8 Ghz core i7 option. What you gain from this is a virtual 8 cores, due to hyper-threading being enabled. The core i5 does not feature hyper-threading, but is still a quad-core processor. #newimacs

@anexanhume: More like pseudo 8 cores. Have people really been writing apps that take advantage of hyper-threading lately?

I mean, Intel hasn't had a ht capable CPU for over 4 years between it's Core Duo and Core 2 Duo cpus... #newimacs

@Lite: hates Illinois Nazis: If it takes advantage of multiple cores, it takes advantage of hyper-threading. People were coding programs with independent threads even before we had dual cores. The advantage of having hyper-threading is the Turbo Boost. If you use 2 threads in one core as opposed to 1 thread in 2 cores, that 1st core can be OC'ed more than those two, yielding higher performance. #newimacs

@Lite: hates Illinois Nazis: All you need to take advantage of it is more threads running concurrently. Even if NONE of your apps take advantage of HyperThreading directly, you will benefit from it.

Hyperthreading wasn't absent from Intel's newer chips because it was inherently bad -- it was absent because it was first baked into the Pentium 4 architecture, which as you may recall, was a steaming pile. They have in recent years ported HT to the Atom and i7 architectures.

HT was a MUST-HAVE for the P4 because it's obscenely-long pipeline made cache misses too expensive. In a CPU with an architecture as short as a Core2Duo it's not nearly as beneficial.

@Wilson Rothman:

So help me understand, because obviously 7 is moar better then 5, but it's not clear from your prior article what I'm missing out on:

The new Core i7 chips, launched last month, are for desktop and mobile. The desktop variant is codenamed Lynnfield, and it more closely resembles its mobile equivalent, codenamed Clarksfield, than it does the Bloomfield monster—dual-channel memory, not triple, for instance.

...

Core i5 is going to be Intel's more mainstream Nehalem-microarchitecture chip brand, and as a broader brand, the chip differentiation gets a little more confusing. Core i5 actually includes some, but not all, of the desktop Lynnfield processors. For now, the only Core i5 chip is quad-core, but you're going to start seeing dual-core Core i5 chips, and soon enough they will make up the bulk of Intel's mainstream processors. In English: Unless you're looking for a crazyfast new computer, your next machine will probably run an Intel Core i5 CPU.

Is i5 not as "crazyfast" as i7? Am I being crazy to hold out? I run an i7 on my desktop and the system screams - but I crave the design sensibility/form factor/software suite of the MB Pro. Help me understand more clearly the i5/i7 tradeoffs, wise one. #newimacs

@Unsolicited Advice: The core i7 features hyper-threading (allow a second thread to be run on each core for a total of 8), and Intel has also hamstringed the motherboards for i5 by limiting the number of PCI express channels (as well as three down to two memory channels). Turns out, game benchmarks don't give a shit. So, gamers are starting to migrate to the i5 cores now. #newimacs

@anexanhume:

So there's a requirement for software support that's likely to be some time coming. Hyperthreading has been in and out of Intel's product lines IIRC because utilization has been low. An i5 will still scream, but processing-intensive tasks like encoding and the like have untapped potential in an i7 that might be incorporated by developers into apps like ProTools, etc. - processors where you're encoding or crunching a lot of data. Sounds safe enough to me.

So then, Steve, my business proposition is clear - shove an i5 or better into the MacBook Pro and you will receive $2K-$3K. But I'm not buying a C2D in late 2009. #newimacs

Just to make things more confusing, The new i7 8-series (Lynnfield) actually goes back to a P55 socket and double-channel RAM, but gets many better benchmarks scores.

I would agree with your take on Celeron, but I wouldn't be so quick to dismiss the Pentium Dual-Core line. They're essentially Core2 chips with less L2 cache, and they run/benchmark pretty nicely for anyone not doing heavy gaming/photo editing. In an office setting they're more than sufficient. #intel

@reddingofish: Pentium D does not equal Pentium Dual-Core (confused yet??)

The Pentium D is essentially 2 Pentium 4 chips stuffed onto one heatsink. Therefore they're ineffecient with energy and run pretty hot.

The Pentium Dual-Core is kind of a hobbled Core2 Duo that uses little energy, runs cool, and runs rings around the Pentium D. #intel

Merom and Penryn share the same branding because they are largely the same architecture. Nehalem was a full new architecture from the alternating Israeli and Oregon design teams, hence the new naming. Now, if Intel decides to keep the Core ix naming for Sandy Bridge, the shit will hit the fan. #intel
