Intel Core i7-5775C Broadwell Processor Review

System Overview & Testing Procedures
We will be installing the Core i7-5775C in our main test bench. Since it uses the same LGA1150 socket we can use the Z97 motherboard and installation is quite the same.


Our test system is comprised of the following components.

Processor: Intel Core i7-5775C / i7-4790K / i7-4770K
Video Card: MSI GTX 770 Gaming
Motherboard: ASUS Z97-A
Memory: 16 GB Crucial Ballistix DDR3
Storage: 120GB Kingston HyperX 3K
Power: Corsair AX860i
Cooling: Thermaltake Water 3.0 Extreme
Case: HighSpeed PC Top Deck Tech Station

For testing the processors the frequency will be set to auto and Intel Speedstep will be turned on. The reason we do is because most people will have this setup on their own PC. This is the default mode if you do not go into the BIOS and change anything. The only thing we will be changing in the BIOS is setting our XMP profile for our memory. The Core i7-5775C will run around 3.3 GHz at idle and will boost up to 3.7 GHz under load.


For comparison purposes we will also be testing the Core i7-4790K and Core i7-4770K using the same test setup and settings. Here are the specifications of all three processors

Core i7-5775C: 3.3 GHz / 3.7 GHz
Core i7-4770K: 3.5 GHz / 3.9 GHz
Core i7-4790K: 4.0 GHz / 4.4 GHz

Keep in mind that the 4770K and 4790K are clocked faster so they should perform better is most tests, but the 5775C is performing at a much lower TDP.
