Intel Ivy Bridge 3770K and Z77 Chipset Reviewed

Cinebench R11.5 CPU

Here in our Cinebench benchmarks, we compare the same three processors once again. This time we also decided to add the Core i7 3960X overclocked at 4.6 GHz as well as the 3770K which we were able to OC to 4.9GHz.

3DMark 11


Here in the Futuremark 3DMark 11 benchmark, we decided to take a middle of the road high-end GPU and test it on the 3960X vs the 3770K to see how much of an effect CPU performance can have on such a test as well as how much the 3770K is expected to perform against the 3960X in games. Looking at these results it is pretty clear that at lower resolutions and settings the 3960X is more powerful and relevant, but as the GPU settings increase it is clear that the different is negligible.

x264 HD Benchmark 4.0

In the x264 HD Benchmark, we were able to see the continued trend of Intel's video performance improvements in Ivy Bridge when compared to older processor architectures. In this test we were able to compare to many other processors which we have tested over time and were able to get a Sandy Bridge processor for this benchmark back when we tested it. Looking at the comparison the 3770K against the 3960 you can see that the 3770's Pass 1 performance outperforms our initial X79 testing and the 2600K but stays very close to the 2600K in the pass 1 test. We also included our overclocked results for this benchmark to show how much performance is gained on this processor when overclocking from 3.9GHz to 4.9GHz. When that is achieved, the 3770K achieves equality with the 3960 in pass 2 and beats it handily in pass 1. Also, as a note, this benchmark is a 720P benchmark and not 1080P.

LinX a Simple Linpack Interface

In our LinX benchmark, we simply wanted to see what kind of raw performance the Core i7 3770K was capable of delivering. Taking a look at that, it would be safe to assume that this processor is capable of about 50 Gflops. This is in comparison to our previous results with the 3960X which achieved 65 Gflops and our 3820 which achieved only 44 Gflops, indicating that based upon raw performance the 3770K is a 10% faster processor in doing linpack computation which is in line with our AIDA64 arithmetic results.
