I think the most noteworthy feature is the 10G Nic which is more conducive to clustering than the standard GigE Nic for other instance sizes. I'm not aware of any other public IaaS provider offering 10G network currently.
In terms of raw performance the x5570 will probably perform very well relative to other IaaS providers. EC2 is one of the few IaaS clouds that utilizes a heterogenous hardware environment to enable better scalability between instance sizes. Other providers like Rackspace Cloud use homogenous environments (Opteron 2374 in the case of Rackspace) and rely on Hypervisor CPU throttling to enable CPU scaling between different instance sizes. On the low end homogenous clouds tend to offer better value but are not well suited for HPC application on the high end (e.g. a 2GB Rackspace Cloud server kills an EC2 m1.small, but the largest 16GB instance lags far behind EC2 m2.* instances). In fact in some homogenous clouds CPU performance is fairly constant from small to larger sized instances (you are essentially just paying for more memory).
I recently wrote a blog post comparing CPU performance of 20 different IaaS providers including EC2 and Rackspace Cloud. In it I used a compilation of 19 different CPU related benchmarks to produce an ECU metric for about 150 different cloud server configurations:

EC2 (with premium support - pricey)
Storm on Demand
SoftLayer
Storm on Demand is a new IaaS platform backed by Liquid Web. Pricing is reasonable, support is good, and they really know what they are doing. I've been using their service for about 3 months now with no issues or downtime.
> I guess, if that sort of thing matters to you. I don't really like relying on third parties for utilities like that. It may matter for your project, if you need automatic-elasticity, more durable off-instance storage, better security, more compute power, more memory. Linode can't provide these features.
> K, but has anybody been making their machines faster? Sure, EC2 has upgraded their m1 hardware the past couple of years, GoGrid is upgrading to Westmere later this year, Storm on Demand has upgraded some of their hardware, Flexiscale has upgraded, and others.
The newer m2 instances use x5550 Nehelem hardware and perform quite well. You'll generally get the most compute power for the money with an m2.xlarge instance (6.5 ECUs) which generally performs much better than the supposedly 20 ECU c1.xlarge Xeon E5410 instance. m2.xlarge can generally be had for around $0.17-0.30/hr (spot pricing) which is very reasonable for 17GB ram (compare to Rackspace Cloud $0.96/hr for 16GB cloud server running on less powerful Opteron 2374 hardware).
If you are interested in other providers, I've done a complete specs/performance/price analysis of 20 different cloud providers including EC2 here: http://blog.cloudharmony.com/2010/05/what-is-ecu-cpu-benchma...
I pay users on mechanical turk to run the speedtest and get about 1000 tests run each month from around the world. The speedtest does a single large file test and another test consisting of lots of small files downloaded concurrently like a browser would download a webpage. The results show that the Anycast CDNs (MaxCDN, CacheFly and Cotendo) generally perform better for the multiple smaller files (i.e. CSS, JS, images) due to usually lower latency, while large files generally download faster on the larger (as in more PoPs) DNS-based CDNs like Edgecast and CloudFront. Overall, the top performers based on this testing are Edgecast and CacheFly. CloudFront does well in Apac, but is only about average in the US. GoGrid or Speedyrails resells Edgecast at very reasonable pay-per-use rates.
If you click on any of the Linode links, you can see when outages occurred, how long they were, and usually an explanation of the outage (if Linode provided one to me)
Dallas: 99.959% Newark: 99.971% London: 99.986% Fremont: 99.992% Atlanta: 100%
I've heard from others here that Atlanta has been a very reliable LN data center for them as well.
