Intel core i7 7700k reaches 5 ghz, impressive performance
Table of contents:
Intel Kaby Lake processors are expected for January 5 at CES Las Vegas, before their imminent arrival leaks that speak of their characteristics and performance are more common. A user has had access to a Core i7 7700K and set it to 5 GHz to see its amazing performance.
Intel Core i7 7700K reaches 4.9 GHz easy
The Intel Core i7 7700K processor is the top of the range of the Kaby Lake family, it consists of a total of four cores at a frequency of 4.2 GHz / 4.5 GHz and with Hipertheading technology to be able to handle up to a total of 8 data threads and thus improve its multi-thread performance. This new processor maintains a 91W TDP for excellent energy efficiency. These processors are manufactured using Intel's already highly refined 14nm + Tri-Gate process so they are expected to be able to achieve higher overclock frequencies than their predecessors.
The user in question has been able to operate their Intel Core i7 7700K at a frequency of 5 GHz with the XMP profile at 4133 MHz. With these figures a great gain is obtained in tests that use memory intensively, in Cinebench R15 a score of 1, 089 points has been reached, while in the Fritz Chess benchmark, 19891 Kilo Nodes per second have been reached. Figures that are much higher than the 913 points and 17049 points obtained in the same tests in their stock frequencies.
| Benchmark Tests | Intel Core i7-6700K (Stock) | Intel Core i7-7700K (Stock) | Intel Core i7-7700K (5.0 GHz) |
|---|---|---|---|
| Cinebench R15 | 886 Points | 913 Points | 1089 Points |
| Fritz chess | 16050 Points | 17049 Points | 19891 Points |
| 3DMark 11 Extreme (Physics Score) | 10124 Points | 10838 Points | 13542 Points |
High frequencies at a price too high for day to day
The Kaby Lakes seem to scale quite well in frequency, the Core i7 7700K was able to hit 4.9 GHz with a voltage of just 1.29V and was stable during the Prime95 test. Reaching 5 GHz was more complicated since it had been necessary to apply 1.49V, a figure too high for a chip at 14 nm.
The bad thing is that at 4.9 GHz the processor has already reached 100ºC, a temperature that is not acceptable to keep it working safely for a long time.
