A screenshot of the chip’s hardware details via CPU-Z, along with a Physics test score in 3DMark Professional Edition, were released as well, showing that AMD is indeed code-naming the new desktop processors “Summit Ridge” (“Zen” is the architecture code name). Here are the CPU-Z details:
| Specification: | AMD Ryzen 7 1700X Eight-Core Processor |
| Name: | AMD K17 |
| Codename: | Summit Ridge |
| Process node: | 14nm |
| Cores: | 8 |
| Threads: | 16 |
| Core voltage: | 0.672 volts |
| Core speed: | 3,899.09MHz |
| Multiplier: | X 39.0 |
| Bus speed: | 99.98MHz |
| Cache – L1 Data: | 8 x 32KB / 8-way |

As for the Fire Strike Physics score in 3DMark, the Ryzen 7 1700X landed an overall score of 17,916 and a 56.88 frames per second physics test score. Other benchmarks performed with the Ryzen 7 1700X include CPUMark 99 Version 1.0, in which the chip scored 583 points. By comparison, the Intel Core i7-5960X scores 561 points.
Here is the chip compared to other processors in Cinebench R15:
| Processor | Score |
| AMD Ryzen 7 1700X | 1537 |
| Intel Core i7-5960X | 1318 |
| Intel Xeon X5650 | 1279 |
| Intel Core i7-6800K | 1259 |
| Intel Core i7-3950K | 1096 |
| Intel Core i7-4790K | 962 |
| Intel Core i7-4790K | 931 |
As we reported last week, the 1700X will retail for around $389, packing eight cores, 16 threads, a base clock speed of 3.4GHz, a boost clock speed of 3.8GHz, 16MB of L3 cache, and a maximum power draw of only 95 watts. In the overall Ryzen lineup, it will fall just under the Ryzen 7 1800X chip that offers a base speed of 3.6GHz and a boost speed of 4.0GHz for around $500. These Ryzen chips will offer the same performance as similar Intel-based processors, but for half the cost.
As a refresher, the “X” in the processor’s name indicates that it will be primed for better overclocking results, and may replace the “Black Edition” models offered in older AMD processor families. There will also be a vanilla version of the 1700X for around $319 that will only consume up to 65 watts of power, and sport speeds of 3.0GHz (base) and 3.7GHz (boost).
Of the 17 Ryzen desktop processors arriving in mere weeks, the Ryzen 7 1800X, the Ryzen 7 1700X, and the Ryzen 5 1600X will require a special cooler listed as HS81 to keep the 95-watt chips from exceeding 60 degrees Celsius. This fan requirement provides better overclocking potential, and is accompanied by AMD’s new Extended Frequency Range technology.
