Is there a list of Geekbench performance metrics for the various Graviton CPUs?

I need a reference point so I can compare it to Intel/AMD and Apple's ARM cpus.

Otherwise it is buzzwords and superlatives. I need numbers so I can understand.

https://instances.vantage.sh/ shows coremark scores for each EC2 instance type.

It always strikes me that the best place of information for a cloud provider is not from that provider but a third party website. This is not a good comment for the cloud provider.

Funny story: When I was at AWS, I found that the easiest way automate instance data collection was by using the Vantage website code (it's on GitHub).

The cobbler's children have no shoes.

We actually recently made the decision to staff someone full time on the site just to maintain it for the community. Even the JSON file for the site gets hit hundreds of thousands of times per day...feels like it's become kind of the de-facto source of truth in the community for where to get reliable AWS pricing information and I believe its powering a pretty remarkable amount of downstream applications with how much usage its getting.

We acquired the site almost 5 years ago and want to continue to improve it for the community. If you have any cloud cost management needs, we're also able to help for our main business here: https://www.vantage.sh/

Awesome to see all the comments on it here!

Thry have to adhere to their marketing words and numbers like "efficiency increase of 99999% in performance per dollar per token per watt per U-235 atom used"

Also, use the ffmpeg fps column to check single threaded score.

While the 5 variant isn't yet available outside of the preview, you can of course spin a 4 up and run geekbench yourself. Plenty of people have and you can find them in the GB DB. And of course most people spin up their specific workload to see how it compares.

Core per core it pales compared to Apple's superlative processors, and falls behind AMD as well.

But...that doesn't matter. You buy cloud resources generally for $/perf, and the Graviton's are far and away ahead on that metric.

[winrid]

Not true at all. Single thread CPU scores for Graviton2 are about half that of Intel, while only being about 20% cheaper at best.

[llm_nerd]

Groan. Yes, absolutely true.

While I know this thread will turn into some noisy whack-a-mole bit of nonsense, an easy comparison is the c8g.2xlarge vs the c8i.2xlarge. The former is Graviton 4 vs Granite Rapids in the latter. Otherwise both 16GB, 15Gbps networking, and both are compute optimized, 8 vCPU machines.

Performance is very similar. Indeed, since you herald the ffmpeg result elsewhere the Graviton machine beats the Intel device by 16%.

And the Graviton is 17% cheaper.

Like, this is a ridiculous canard to even go down. Over half of AWS' new machines are Graviton based, but per your rhetoric they're actually uncompetitive. So I guess no one is using them? Wow, silly Amazon.

The latter is a 4-core machine with 8 HyperThreads. This doesn't actually matter to your price-performance metric but is worth mentioning because it's the reason why the Intel part performs so comparatively poorly. They're fast chips, they're just wildly uneconomical. If you wanted to compare equal core counts (c8i.4xlarge vs. c8g.2xlarge), then the Intel instance type wins on performance but the Graviton is 58% cheaper.

[winrid]

Groan. Absolutely not. :)

c8g passmark score: 1853 c8i passmark score: 3008

I guess the fps column isn't a good representation of single thread score. Also looking at the passmark scores for i4i vs i4g, i4g is about 1k and intel is about 2k, and the more modern Graviton equivalent of i4 is the same price, so...

Silly amazon.

[llm_nerd]

So confident. And exactly the whack-a-mole nonsense I predicted.

See the comment by electroly. They actually know what they're talking about.

See, the FPS score is for the whole machine. The c8g gives you 8 real cores. The C8i gives you 4 real cores, 4 hyperthreading pseudo-cores. So for those two machines the c8g unequivocally gives you more absolute computing performance, regardless of the passmark single thread (on a single core) on the c8i being better than a single core on the c8g. And the c8g comes at a big discount as well.

That's...the point. The Graviton processors are cheaper per core, and lower performance per core, and you make it up in bulk. You get more performance per $ if you're okay with the ARM stack and your software is good with it, and this is basically universally true comparing Graviton instances versus Intel/AMD alternatives.

You're wrong. Maybe cite some other random nonsense now?

[winrid]

Single thread performance is important for many workloads. It's not nonsense. Things like index builds on an i4g vs i4i could be half as slow. That's really important!

I don't know why you continue to be a fucking asshole. It's just a hosting provider. Go touch grass.

[wmf]

Do you realize we're talking about Graviton5 now?

[winrid]

The Graviton5 instances I've been comparing to intel are the same price...
