VR Zone received word that Intel is going to ship three Sandy Bridge SKUs that will not feature built-in graphics:
Besides the Core i5-2550K Intel is also planning on launching the Core i5-2380P and the Core i5-2450P where we presume the P has something to do with the lack of an active graphics core. We'd guess that these are parts where the graphics core wasn't working properly, but where the rest of the chips were fully functional and as such Intel decided to launch a few models without graphics. Although a lot of users don't use the Intel graphics that is now part of every single Sandy Bridge processor to date, there are some downsides to this move as for example you can no longer take advantage of Intel's Quick Sync technology.
The Core i5-2380P is clocked at 3.1GHz, the same as the Core i5-2400 and it has the same Turbo Boost frequency of 3.4GHz. The Core i5-2450P is the odd one out here, as it's clocked at 3.2GHz with a top Turbo Boost frequency of 3.5GHz, in other words 100MHz slower than the Core i5-2500. The Core i5-2550K on the other hand is 100MHz faster than the Core i5-2500K at 3.4GHz with a top Turbo Boost clock speed of 3.8GHz. All three models have 6MB cache, but none of them have VT-d or TXT support, a feature all previous non-K SKUs have had in the Core i5 family.
