Intel Core i7-3770K Ivy Bridge LGA1155 Processor Review - Processors  1



For a single thread, again the IVB architecture takes the performance lead and is able to maintain a solid showing all the way through. At the full 8 thread count the 3770K is 13-14% faster than the 2600K.

 

TrueCrypt Encryption


TrueCrypt is one of the most popular pieces of software for disk encryption and it includes a handy benchmark mode to test the capabilities of your processor.  Keep in mind that many modern CPUs include AES acceleration that is used throughout TrueCrypt.

Intel Core i7-3770K Ivy Bridge LGA1155 Processor Review - Processors  2

Our first result is reporting on the initial AES result only and you can tell immediately which processors do NOT include AES acceleration.  The new Core i7-3770K is able handle 3.7 GB/s of encryption and decryption falling behind only the Core i7-3960X at 5.7 GB/s.  The second graph shows an average of the rest of the results where the new IVB CPU is able maintain a 19% performance lead over Sandy Bridge.
