Making sense of Intel's Core i3, Core i5, and Core i7 brands

Intel has announced a new brand structure that, over time, promises to do away with a complex structure of too many product names with "a simplified family of Core processors spanning multiple levels".

That's the theory, but we're already a little confused by Intel's plans going forward. Judging by a post by Intel communications manager Bill Calder on the Intel Technology Blog, it seems as though the semiconductor giant is taking a leaf out of NVIDIA's book by attempting to unify its core product line with a common nomenclature, i.e. Core i#.

However, looking forward, Bill's information doesn't quite paint a crystal clear picture of what will happen in years to come. We know that the much-loved Core 2 Duo and Core 2 Quad brands will one day go the way of the Dodo, but the new brands coming in - Core i3 and Core i5 - aren't exactly made clear. What are they? Well, we know now that the Core i5 moniker will be used by upcoming Lynnfield parts, but the rest remains largely a mystery.

With Intel leaving the door agape for conjecture, here's what we think might be the future line up of Intel's flagship brand. Please keep in mind that this is merely hearsay, and we're simply doing our best to put two and two together.

Now for some observations. The above table, built from a combination of mostly fact and a little speculation, focuses solely on Intel's Core range. Readers should be aware that Intel's Atom, Celeron and Pentium brands will live on unchanged. Why not bring them under the Core umbrella? Well, Intel wants to keep its Core brand limited to performance parts - and, let's face it, a Core i1 just doesn't sound quite right.

So, given Intel's comments, we can speculate and assume that the still-going-strong Core 2 line will live on under the Core i3 brand, where it'll later be joined by the 32nm mobile Arrandale range.

It's important to note, also, that Intel states that the Core i3, Core i5 and Core i7 names are not brands but modifiers that signal different features and benefits. Hence Lynnfield, a mainstream Nehalem part, will appear as both Core i5 and Core i7 when it reaches market. Trying to make sense of it, we're assuming that the Core i5 Lynnfield will be without Hyper Threading, whereas the Core i7 alternative will feature eight threads - making it a slower clocked Bloomfield, albeit without QPI and tri-channel memory.

Still with us? Good, because there's also the matter of Gulftown - a six-core derivative of Bloomfield that we reckon could emerge as Core i9 when it reaches the market sometime next year. Should that be the case, we'll see Intel's range span the following multiple levels - Core i3 for mainstream, Core i5 for performance, Core i7 for high performance, and Core i9 for extreme.

It's all starting to get a little clearer, but model names remain a mystery. Once Core 2 Duo and Core 2 Quad are phased out, will Intel continue to make clear the number of cores featured in a single processor? If so, will we see a Core i3 Duo and a Core i3 Quad? Maybe, maybe not. On top of that, how will it identify parts with an IGP? Will the Clarkdale-based Core i5 arrive with a name along the lines of Core i5 G820? With the G pointing out integrated graphics? Who knows.

All that remains unclear, but Intel reckons the simplification process will come good, someday. What do you think, dear readers? Are we painting a logical picture, or would you like to see Intel's Core line up branded differently? Share your thoughts in the HEXUS.community forums.
