has provided customers with the configuration and budget for Alibaba Cloud ECS server in the past two days, and found that the price gap between the g7 instance family and the g6 instance family of Alibaba Cloud ECS server has become very small. So today we will take a look at the difference between the g7 instance family and the g6 instance family, and how we should choose.
First, we take the general instance specification as a benchmark to roughly look at the main parameters of the two instance families:
g7 general instance
processor and memory ratio is 1:4
processor: using the third generation Intel® Xeon® extensible processor (Ice Lake), with a base frequency of 2.7 GHz, and a full-core turbo frequency of 3.5 GHz
only supports ESSD cloud disk
supports vTPM characteristics, and rely on the TPM/TCM chip to realize the startup chain trustworthy measurement from server to instance, providing ultra-high security capabilities.
g6 general instance
processor and memory ratio is 1:4
processor: 2.5 GHz main frequency Intel ® Xeon ® Platinum 8269CY (Cascade Lake), turbo frequency 3.2 GHz 1
supports ESSD cloud disk, SSD cloud disk and high-efficiency cloud disk
From the above content, we can see the main differences between the g7 instance family and the g6 instance family:
first, CPU
g6 instance family uses 2.5 Intel ® Xeon ® Platinum 8269CY (Cascade Lake) with GHz main frequency, turbo frequency 3.2 GHz. The g7 instance family uses the third generation Intel® Xeon® scalable processor (Ice Lake), with a base frequency of 2.7 GHz and a full-core turbo frequency of 3.5 GHz.
Second, storage
g6 instance family supports ESSD cloud disk, SSD cloud disk and efficient cloud disk. g7 instance family only supports ESSD cloud disk.
Third, network packets,
g6 instance family's most basic 2-core 8GB instance is 300,000 PPS, while g7 instance family's 2-core 8GB instance is 900,000 PPS
Fourth, vTPM
g7 supports vTPM features, relying on TPM/TCM chips, it realizes the startup chain trustworthy measurement from server to instance, and provides ultra-high security capabilities.
Next, let’s compare the prices of the same configuration.
From the above price, the price difference between the price of the g7 instance family and the g6 instance family has reached one hundred yuan per level for the ECS server with the same configuration. Spending a few hundred yuan more can result in higher CPUs, greater network throughput, and more secure features. Xiaoxin recommends that new ECS servers try to choose products from the g7 instance family. If you want to choose a cheaper and efficient cloud disk, you can only consider products from the g6 instance family.
