The instances use 2.5 GHz intel Xeon E5-2670v2 processors with Turbo mode enabled. They also benefit EC2's new enhanced networking. You will see significantly higher performance (in terms of packets per second), much lower latency, and lower jitter when you launch these instances from within a Virtual Private Cloud (VPC).
We'll be releasing more information at launch time. Here are the basic specs to tide you over until then:
|Instance Name||vCPU Count||RAM
||Instance Storage (SSD)|
|i2.large||2||15 GiB||1 x 360 GB|
|i2.xlarge||4||30.5 GiB||1 x 720 GB|
|i2.2xlarge||8||61 GiB||2 x 720 GB|
|i2.4xlarge||16||122 GiB||4 x 720 GB|
|i2.8xlarge||32||244 GiB||8 x 720 GB|
The i2.8xlarge instances will be able to deliver 350,000 random read IOPS and 320,000 random write IOPS. Numbers for the other instance types will be proportionally smaller, based on the number of SSD devices associated with the instance.
Stay tuned for more information about the I2 instances.
