Intel Ivy Bridge 3770K and Z77 Chipset Reviewed

SiSoft Sandra 2012



In this test, SiSoft Sandra tests the mathematical computation capabilities of the processors with two different tests. As you can see here, the Core i7 3770K beats out the Core i7 3820. This does indicate that on a purely computational basis, the Core i7 3770K is a superior processor, even if by a relatively small margin.



Here in the Processor Multimedia Benchmark, we essentially see more of the same with the 3770K edging out the 3820 by quite a bit more than in the previous test, but still quite a bit behind the 3960X. Admittedly, we wouldn't expect the 3770K to beat the 3960X, but it would be nice to see it competing more closely. Then again, it is a bit hard to expect that when Ivy Bridge is simply a die shrink of the Sandy Bridge architecture. Nevertheless, these results are pretty good and continue to tell the story that Intel has indeed significantly improved video processing performance.



Here we see the multi-core efficiency between the processors and we can see that the 3770K actually has the best inter-core latency, but also the slowest inter-core bandwidth. What should be interesting is to see how Ivy Bridge-E stacks up against Sandy Bridge-E (3960X).



The SiSoft Sandra 2012 Cryptography Benchmark shows a mixed bag of the 3770K beating the 3820 in hashing bandwidth test, but losing in encryption/decryption test. As expected, the 3960X once again wins both tests in this benchmark.


IIn this test, we have the 3770K going up against two Sandy Bridge-E processors with Quad-Channel memory. Admittedly, we didn't for a second expect the 3770K to compete with the 3820 or 3960X, but we still wanted to see how well it performed against them when taking into consideration the massive expected performance differential. Even though we didn't have a Sandy Bridge processor to test against it, based off of the database's existing benchmarks of Sandy Bridge, the 3770K did beat it by a slight margin.
