Interestingly, Intel plans to start segreggating their products based on performance into three categories; good, better, best (there is no bad/average in Intel haha). This categories will then be labeled as Core i3, Core i5 and Core i7 respectively. So, let's say you plan to buy a new PC/laptop soon, how do you know which you are getting? Anandtech has done a good summary with the below tables:
Desktop Processor | Cores | Threads | Turbo |
Intel Core i7 | 4 | 8 | Yes |
Intel Core i5 | 2 or 4 | 4 | Yes |
Intel Core i3 | 2 or 4 | 4 | No |
Mobile Processor | Cores | Threads | Turbo |
Intel Core i7 | 2 or 4 | 4 or 8 | Yes |
Intel Core i5 | 2 or 4 | 4 | Yes |
Intel Core i3 | 2 or 4 | 4 | No |
With the above, we can clearly see the performance gaps betwwen each category. The Core i3 lineups are the ones with no HyperThreading and no Turbo Mode to temporarily boost when less cores are utilized. The Core i5 will have Turbo but with no HyperThreading and finally the Core i7 with both features turned on thus having the best performance of all.
This goes against what I believe some of you have concluded that Bloomfield or Socket 1366 will be maintained as the Core i7 and that the new Lynnfield processor will be marketed as Core i5. Because Intel chose not to use QPI link and number of memory channels as comparison, it basically means that the Core i7 will be a mix of both LGA-1366 and LGA-1156 sockets. To differentiate, we have the sub categories:
Core i7 9xx Series - LGA1366
Core i7 8xx Series - LGA1156
Core i5 6xx series - LGA1156
Core i3 5xx Serie - LGA1156
There is no talk about what socket Clarksfield will be using though it is rumored to be using a totally different socket compared to Lynnfield. This is going to complicate the marketing further I think.
Anyways, whether this is the right strategy or not, I believe it will vary from each person's perspective. I mean previously, if I see a core 2 Quad or Core 2 Duo, I know I'm getting a quad core or dual core CPU respectively and its all about choosing the GHz. Now, I have to worry about what socket the CPU I'm getting is using and will it be compatible with my current hardware. Big headache to plan my upgrade path now :S
What you guys think?
