Intel 7th Generation Core i3 7350K Testing:

To validate that level of performance delivered by Intel's Kaby Lake Core i3 7350K, I will be running it and its comparison products through OCC's test suite of benchmarks, which include both synthetic benchmarks and real-world applications. The gaming tests will also consist of both synthetic benchmarks and actual gameplay, in which we can see if similarly-prepared setups offer any performance advantages. The system will receive a fully updated, fresh install of Windows 10 Professional 64-bit edition, in addition to the latest chipset drivers for each board and GeForce drivers for the NVIDIA GTX 1080 8GB Founders Edition. To ensure as few variables as possible, all hardware will be tested at their stock speeds, timings, voltages, and latencies, unless otherwise stated. After stock speed testing, each processor will then be overclocked as much as possible, while still maintaining full stability.

Overclocking:

  • Intel Core i3 7350K: 100x49 4900MHz 

Much like with the Core i7 7700K, the overclocking methodology is pretty much what I have come to expect when overclocking an Intel processor. Prime 95 stability can be had with a tweak to the voltages after bumping up the core clock multiplier. Knowing that Kaby Lake has 5GHz potential, I started with the rough settings I used on the Core i7 7700K, but with the core clock multiplier set to 50 x 100 instead of 49 x 101MHz that I used to get the 7700K stable. I could not get 5.0GHz stable no matter the voltage, up to 1.475v. Knowing that's way too high for this 14nm silicon, I dropped the multiplier down to 49 along with dropping the voltage to an applied 1.375 and the chip came around with a stable final core clock speed of 4900MHz. My final tweak was getting the cache ratio overclocked. I left the voltage on auto to see where it liked to fall with each bump in cache clock speed. I eventually reached a cache ratio of 45 to go with the core clock ratio of 49 to drive performance a little higher. They say there is not much performance to be gained from boosting up the cache clock speed, but it does help across the board.

Ultimately, I was able to see a 700MHz all core boost over the factory 4.2GHz base clock speed. Not too shabby when you think about it. The additional core clock speed should drive performance forward when working with fewer cores/threads.

 

Maximum Core Clock Speed:

Each CPU has been tested for stability at the listed overclocked speeds. These clock speeds will represent the level of performance shown by the overclocked scores in the testing.
