intel(r)=Intel

celeron(r)=Celeron

The r in the brackets means registered

If Celeron There is not r after Yang, but d, which means it is a new Celeron

The old Celeron's secondary cache is 128kb, and the highest frequency seems to be 2. Below a few, the new Celeron D's L2 cache has 256kb, 512kb, etc., and the main frequency is up to 3.0. I forgot the main body, but the Celeron's overclocking is very good. I used to use the Celeron d2.53, and it was overclocked to 3.06. I'm using it now. Now my laptop is an I5, and the L3 cache alone is 3MB. Compared with before, it's just a drop in the bucket.
