AMD Ryzen 7 1700 and 1700X CPU Review
We've already examined AMD's top dog Ryzen 7 1800X CPU, but now we spend some time checking out the cheaper 1700 and 1700X processors.

Introduction

I recently took a look at AMD's top dog Ryzen 7 1800X 8-core/16-thread CPU, and while it's multi-core performance was dangerously fast, it also costs upwards of $500. AMD also launched two more affordable models, with identical core counts and even the same amount of cache. These two processors do have lower clock speeds. Now, I already went over the microarchitecture, chipset, and 1800X in my review located here. Today, I will exclusively cover the Ryzen 7 1700 and 1700X CPUs.

Last week AMD launched three high-end SKUs. The 1700X and 1700 are designed to bring eight real cores (16-threads) to the masses, and they compete directly with Intel's i7-6800K (6-Cores/12-threads) and i7-7700K (4-cores/8-threads). Their price points are very attractive, with the 1700X at $399 and the 1700 at $329. The only difference between the Ryzen 7 1800X and 1700X is their clock speeds, which makes the 1700X worth it for those who want to save $100 and overclock to get to 1800X speeds.

We can see how AMD is naming their new processors, and through this naming scheme, we find that the 1700X and 1700 only have one thing other than clock speeds that set them apart; XFR. AMD's eXtended Frequency Range (XFR) technology is similar to what Intel has done with Turbo Boost 3.0, it increases the clock of one core above boost speeds, but you don't need to install software to get it to work.

 

XFR uses AMD's SenseMI technology's monitoring capabilities to gauge if the processor is capable of sustaining high clock speeds. If you use great cooling, the CPU will increase its clock speeds an extra 100MHz (give or take a fewMHz). XFR requires an X370 chipset motherboard and a Ryzen 7 1000X CPU, and the Windows power profile set to High Performance.

 

While the 1800X has a base clock of 3.6GHz, a boost of 4GHz, and a 4.1GHz XFR boost, the 1700X has a base of 3.4GHz with a boost of 3.8GHz, and a 3.9GHz XFR boost. The 200MHz difference isn't much considering you save $100. The base clock of the 1700 is 3.0GHz with a 3.7GHz boost, and it doesn't offer XFR (even though the chart above says it has some XFR capabilities.

 

All three CPUs have the same amount of cache and are otherwise identical except for clock speeds and TDP. The Ryzen 7 1800X and 1700X have 95W TDPs, while the 1700 has a TDP of 65W. The 30W savings in power is really quite impressive.

 

 

Pricing

 

The Ryzen 7 1700X costs $399 while the Ryzen 7 1700 costs $329.99.
