Intel 11th Generation Core Review

Intel will officially release the Rocket Lake 11th-generation desktop Core on March 16, and the evaluation and listing will be lifted on March 30. However, in some regions such as Germany, dealers have begun to sell new products in a big way. The main model is i7- 11700K.

AnandTech, an authoritative hardware evaluation website, also bought one, made a detailed evaluation, and emphasized that doing so does not violate the NDA confidentiality agreement, and even specifically asked Intel, the latter remained silent, neither affirmed nor denied.

The evaluation is very long and detailed. Let’s take the key points and talk about it. At the end of the month, we will also offer Kuaidi’s own first evaluation.

The i7-11700K specification has 8 cores and 16 threads, the base frequency is 3.6GHz, the full-core acceleration is 4.6GHz, the single-core acceleration is up to 5.0GHz, the secondary cache is 4MB, the tertiary cache is 16MB, and the thermal design power consumption is 125W.

Compared with the 10th generation i7-10700K, the base frequency is 200MHz lower, the maximum acceleration is 100MHz lower, and the thermal design power consumption is the same.

The actual test found that the frequency of i7-11700K can be accelerated from 800MHz to 4.9GHz in 17 milliseconds.

Intel claims that the 11th generation Core can have a 20% performance improvement. According to SPEC’s actual measurement, the single-thread and multi-thread floating-point performance of the i7-11700K are increased by 19.0% and 19.5% respectively, which almost perfectly meets expectations, but single-core and multi-core Integer performance is only improved by 13.0% and 7.3% respectively. Of course, the ranges in different scenarios are very different.

In the actual test, almost every item of i7-11700K can be equal to or exceed i7-10700K, especially in Dolphin, Blender, POV-Ray, Agisoft, Handbrake, and Web tests. Considering that the frequency is decreasing, it is not easy.

The biggest improvement is 3DPM AVX. After all, this time it supports the AVX512 instruction set, which is more than 6 times that of i7-11700K.

The game performance is a bit disappointing, and more often it is even going backwards. Although this level of U is not enough to significantly affect the actual gaming experience, it shouldn’t be.

After analysis by AnandTech, it is believed that the main reason is that the third-level cache latency of the 11th generation has become higher, from about 43 cycles to about 51 cycles, which in turn affects the communication delay between cores from 18-24 nanoseconds to 28-30 Nanoseconds. This is obviously the design of Cypress Cove architecture.

Power consumption and temperature burst. The measured peak power consumption of Agisoft Photoscan 1.3 is about 180W, the stable stage is about 130W, 155W, the highest temperature is 70℃, and most of the time it is about 60℃.

The PVO-Ray AVX2 test peak power consumption is about 225W, this state can last for more than 10 minutes, the maximum temperature during the period is 81℃, and the all-core frequency is stable at 4.6GHz.

The 3DPM AVX-512 test usually runs for 10-15 seconds and then rests for 10 seconds. The peak power consumption is as high as 292W, and the full-core frequency is still 4.6GHz, sometimes dropping to 4.5GHz.

The temperature is even more terrifying. It runs above 90°C, and sometimes breaks through 100°C, reaching a maximum of 104°C.
