That's not correct. AWS sells Graviton 3 based EC2 instances at a higher price than Graviton 2 based instances!
For example a c6g.large instance (powered by Graviton 2) costs $0.068/hour in us-east-1, while a c7g.large instance (powered by Graviton 3) costs $0.0725/hour [1]. Both instances have the same core count and memory, although c7g instances have slightly better network throughput.
I believe that is pretty unusual as, if my memory serves me right, newer instances family generations are usually cheaper than the previous generation.

- pattato 4y agoDid you create these?
- WASDx 4y agoCould it be due to increasing global energy prices?
- usefulcat 4y agoI don't follow. You seem to be implying that Amazon would like to reduce their electricity usage. If so, shouldn't they be charging less for the more efficient instance type?
- nine_k 4y agoNo, they charge for compute, which the new CPU provides more of, even though it consumes the same amount of electricity as a unit.
- jeffbee 4y agoIt would be irrational to expect a durable lower price on graviton. Amazon will price it lower initially to entice customers to port their apps, but after they get a critical mass of demand the price will rise to a steady state where it costs the same as Intel. The only difference will be which guy is taking your money.
- zrail 4y agoDo you have a cite on Amazon raising prices like that at any other point in their history?
- greatpostman 4y agoI don’t think Amazon has ever raised their prices. This comment is based on nothing
- orf 4y agoI mean, they just raised their graviton prices between generations. I don’t think the point was that they would increase the cost of existing instance types, only that over time and generations the price will trend upwards as more workloads shift over.
- staticassertion 4y agoI wouldn't call that "raising prices"... you can still use Graviton 2 if it's a better price for you.
- losteric 4y agoPrime has gone up quite a bit Nearly every business seeks to maximize profit. Right now AWS is in growth phase - why wouldn't they raise rates in the future?
- jhugo 4y agoI dunno, this take is a bit weird to me. The work we did to support Graviton wasn't "moving" from Intel to ARM, it was making our build pipeline arch-agnostic. If Intel one day works out cheaper again we'll use it again with basically zero friction.
- mastax 4y agoGiven the surrounding context I read that sentence to mean that focusing on compute density allowed them to sell each core at a lower price vs focusing on performance, not that Graviton 3 is cheaper than Graviton 2.
- arpinum 4y agoGraviton 2 (c6g) also cost more than the Graviton 1 (a1) instances
- adrian_b 4y agoBased on the first published benchmarks, even the programs which have not been optimized for Neoverse V1, and which do not benefit from its much faster floating-point and large-integer computation abilities, still show a performance increase of at least 40%, so greater than the price increase. So I believe that using Graviton 3 at these prices is still a much better deal than using Graviton 2.
- electroly 4y agoM6i is the same price as M5 rather than cheaper as well. It seems like they've had difficulty driving prices down this generation.
