We tested the Ryzen 7 1700, the entry CPU from AMD’s new Ryzen 7 lineup. It has eight cores, 16 threads, 3.0 GHz base clock, 3.7 GHz turbo clock, TDP of 65 W, and uses the new AM4 socket. Check it out!
After several years, AMD finally launched a new generation of CPUs, based on a brand new architecture, called Zen, using the new AM4 socket. The first CPUs based on this new socket are called Ryzen 7 and they are high-end processors. AMD already launched the Ryzen 5 (mainstream) processors, and the Ryzen 3 (entry) models will be available soon.
The first models launched were the Ryzen 7 1700, the Ryzen 7 1700X, and the Ryzen 7 1800X, all of them with eight cores and 16 threads, thanks to the SMT (Simultaneous Multi-Threading) technology, similar to Intel’s Hyper-Threading technology, which simulates two logic cores on each physical core. We already tested the Ryzen 7 1700X, click here to read the review.
Ryzen CPUs use the new AM4 socket, and are compatible with DDR4 memory. This means they are incompatible with “old” motherboards that use AM3+ and FM2+ sockets.
These new CPUs are manufactured under 14 nm “FinFET” technology. Each core has 128 kiB L1 cache and 512 kiB L2 cache, and there is an 8 MiB L3 shared cache for each four-core block. The Ryzen 7 1700 have two of those blocks, with a total of 4 MiB of L2 cache and 16 MiB of L3 cache. That’s why AMD says the CPU has a 20 MiB cache.
Ryzen CPUs have unlocked clock multiplier, which allows the user to overclock it simply by changing the settings on the motherboard setup, if it uses one of the chipsets compatible with this feature (B350 e X370).
Besides that, Ryzen CPUs have a set of features called “SenseMI”, where the CPU detects and controls the clock in 25 MHz steps, according to several factors.
The Ryzen 7 1700X and Ryzen 7 1800X are sold without a cooler, but the Ryzen 7 1700 comes with a cooler named “Wraith Spire”. The mounting frame used by AM4 socket is similar to the older ones with respect to the “hook” where the CPU cooler holds. So, coolers that use this center hook (like the Wraith) are compatible with AM4 socket. However, the motherboard holes are different, so AM3/FM2 coolers which mounting system uses the motherboard holes will not fit.
The closer competitor of the Ryzen 7 1700 is the Core i7-7700K. So, we compared the Ryzen 7 1700 to the Core i7-7700K and to the Ryzen 7 1700X. We also included in our comparison a FX-8350, in order to compare performance to the previous generation.
Figure 1 shows the box of the Ryzen 7 1700.

In Figure 2 you see the box contents: the Wraith Spire cooler (that has RGB lights inside the top frame), a cable to control the cooler lights, the CPU itself, and a case sticker.

The Wraith Spire cooler has a copper base and comes with preapplied thermal compound.

As the Ryzen 7 1700X has no integrated video, we used a GeForce GTX 1080 video card on all tests.
