At CES 2020, amd officially released the sharp dragon 4000 series notebook processor, which is based on the new 7Nm process, Zen 2 CPU architecture, Vega GPU architecture, including the sharp dragon 4000U series for the light and thin version, the sharp dragon 4000H series for the game version, and an entry-level quick dragon 3000u series.
At the meeting, Su Zifeng only introduced two flagship models, the sharp dragon and the sharp dragon 7 4800h. In fact, there are quite a lot of new models. Let's take a look at them in detail.
There are five models of the sharp dragon 4000U series, and the power consumption of the thermal design is only 15W. This is the first time that the light and thin version ushers in the core thread, but note that there are three models that do not support multithreading.
Reebok 7 4800u: 8 core 16 thread, main frequency 1.8-4.2ghz, 2-level cache 4MB, 3-level cache 8MB, Vega 8 GPU, 512 stream processors, frequency 1750mhz.
Ruilong 7 4700u:8 core 8 thread, main frequency 2.0-4.1 GHz, secondary cache 4 MB, tertiary cache 8 MB, integrated Vega 7 GPU,448 stream processors, frequency 1600 MHz.
Ruilong 5 4600u: 6 core 12 threads, main frequency 2.1-4.0ghz, 2-level cache 3MB, 3-level cache 8MB, Vega 6 GPU, 384 stream processors, frequency 1500mhz.
Ruilong 5 4500u: 6 core 6 threads, main frequency 2.3-4.0ghz, 2-level cache 3MB, 3-level cache 8MB, Vega 6 GPU, 384 stream processors, frequency 1500mhz.
Ruilong 3 4300u: 4 core 4 threads, main frequency 2.7-3.7ghz, 2-level cache 2MB, 3-level cache 4MB, Vega 5 GPU, 320 stream processors, frequency 1400mhz.
AMD claims thatCompared with the previous generation, the power consumption of the sharp dragon 4000U is reduced by up to 20%, the energy efficiency is up to 2 times, and the delay of energy-saving state entry and recovery is up to 5 times. In addition, the new memory supports lpddr4x.
In terms of performance, compared with the flagship model i7-1065g7 (4-core 8-thread / 1.3-3.9ghz / 15W) of Intel 10nm ice lake family, the CPU is about 4% ahead of single thread, the CPU is about 90% ahead of multithread, the content creation is up to 49%, and the GPU graphics is about 28%, which can be competent for most online games and mainstream games under 1080p low image quality.
The sharp dragon 4000U will have more than 20 designs in the first quarter and more than 100 designs in the year.
