Today, Intel has released seven new Sandy Bridge based CPUs: three Core i5 and four Celeron models. All the i5 SKUs are desktop models, whereas the Celeron SKUs are mobile: two standard voltage and two ultra-low voltage models. Below is a table of the new SKUs.

You may be wondering what the P at the end of two Core i5 SKUs stands for. Intel has not updated their product database yet so we aren't 100% sure, but VR-Zone is reporting that it implies a GPU-less model. VR-Zone is also stating that the i5-2550K is GPU-less as well, which would be a step down from the i5-2500K that features Intel HD 3000 graphics.

This is a logical move as Intel must have a stack of chips with fully working cores and other parts, but the IGP isn't functional. On the other hand, it's good to keep in mind that a disabled IGP means no Quick Sync. Since the price and specification differences between the models with IGP and the models without is so small, we recommend buying a model with the graphics as you never know when you might want/need Quick Sync or more video outputs. The 100MHz increase in frequency isn't worth the loss of the IGP.

As for the CPUs in general, i5-2550K is obviously the successor of i5-2500K. It has 100MHz (i.e. one CPU bin) higher frequencies than i5-2500K and is priced $9 higher. Similarly, i5-2450P and i5-2380P are successors of i5-2400 and i5-2320—the i5-2450P being $11 more expensive and i5-2380P being priced the same as its predecessor. Celeron B815 replaces B810 at the $86 price point; they share the same core specs while the GPU gets a bump in maximum clock from 950MHz to 1050MHz. Meanwhile, B720 succeeds B710 with 100MHz higher frequency and the same $70 price tag. Celeron 867 becomes the new high-end ULV Celeron by taking the place of 857 at the price point of $134 with 100MHz higher frequency, and 797 increases the frequency by 100MHz to 1.4GHz in the $107 category and replaces 787.
