We will be outlining the Ryzen Threadripper CPUs' performance while using an ASUS ROG Zenith Extreme X399 Socket TR4 motherboard. A 32GB (4x8GB) kit of G.Skill's 3200MHz CL14 DDR4 memory serves our test system.

Today's comparison processors come in the form of:

• Skylake-X i9-7900X (10C20T).
• Broadwell-E i7-6800K (6C12T) and i7-6950X (10C20T).
• Kaby Lake (and Kaby Lake-X) i7-7700K (4C8T) and i7-7740X (4C8T).
• Ryzen 7's 1700 (8C16T) and 1800X (8C16T).
• Ryzen 5's 1600X (6C12T).

Each processor is tested at its default out-of-the-box settings and when overclocked to a reasonable level. For the Intel CPUs, we ensured that forced-turbo was disabled so that Intel's defined Turbo Boost parameters were functioning correctly. As such, all-core load frequencies for the tested chips are as follows:

• Ryzen Threadripper 1950X = 3.7GHz.
• Ryzen Threadripper 1920X = 3.7GHz.
• Core i9-7900X = 4.0GHz (most of the time, with Handbrake or synthetic stress tests as an exception).
• Core i7-6950X = 3.4GHz (most of the time, with Handbrake or synthetic stress tests as an exception).
• Ryzen 7 1800X = 3.7GHz.
• Ryzen 7 1700 = 3.2GHz.
• Core i7-6800K = 3.5GHz.
• Core i7-7740X = 4.5GHz.
• Core i7-7700K = 4.4GHz.
• Ryzen 5 1600X = 3.7GHz.
