The Sisoft Sandra 2014 SP2a benchmark utility measures pretty much all of your system components, but we’ll be using it to focus on memory and CPU performance!

Results: The Intel Core i7-3770K Ivy Bridge processor had 27.58GB/s of memory bandwidth with our Corsair Dominator Platinum 2133MHz memory kit and CL9 timings. This is a solid number, but the Intel Core i7-4770K had 27.91GB/s of memory bandwidth and the Core i7-4790K came in at 28.00 GB/s with the same exact kit. There isn’t much difference between Haswell and Ivy Bridge architectures when it comes to the memory controller as you can see from this bandwidth test.

Results: The Intel Core i7-4770K and Core i7-4790K CPUs are significantly faster than the Intel Core i7-3770K in the Multi-Media test due to the the new Intel AVX2 instruction set available on the Haswell processors. The Intel Core i7-4790K was able to really outperform the Core i7-4770K due to the having a 4.4GHz boost speed versus just 3.9GHz. This gave the Core i7-4790K a nice 12.3% performance boost over the Core i7-4770K.

Results: All the new mainstream and high-end desktop processors support AES-NI and have pretty good Cryptographic Bandwidth numbers. The Core i7-4790K scored 7.24 GB/s versus the 6.80 GB/s found on the Core i7-4770K.

sandra-arith

Results: In the Sandra 2014 SP2a CPU Arithmetic Benchmark the Intel Core i7-47790K was found to be 20.8% faster than the Core i7-3770K processor and 12.3% faster than the Core i7-4770K.
