Take two Nehalem dies, turn them 90 degrees, add a lot of system interface logic and 8 MB extra of L3-cache and you get - very oversimplified - the impressive Nehalem EX, alias "Beckton". The new Xeon MP is an impressive monster, just like it's predecessor Dunnington. Dunnington consisted of 1.9 Billion transistors, the Xeon MP based on the "Nehalem"...

We promised you a new datapoint, a new independent virtualization benchmark in "a few days". Those "few days" have become a week in good "IT at Anandtech" tradition. :-) But this wednesday, unless Murphy strikes us hard, the article will be online. It will offer a refreshing look at the virtualization performance, the result of months of work. Liz...

In our last article about server CPUs, I wrote:
"the challenge for AMD and Intel is to convince the rest of the market - that is 95% or so - that the new platforms provide a compelling ROI (Return On Investment). The most productive or intensively used servers in general get replaced every 3 to 5 years. Based on Intel's own inquiries,...

My last post generated quite a bit of discussion, some of it based on misunderstandings. In this post I'll try to make a few things more clear. In a previous post, I pointed out that there are a good indications that a dual Nehalem EP has a 40 to 100% advantage over Shanghai (depending on the application, based on the SAP and Core i7 workstation benchmarks).
If...

Now that the actual conference is behind us, and we've found our way back to the lab, it's time to finish what we started. First off, an apology for our radio silence on day 3: our schedule turned out to be quite a bit more packed than we thought it was, so finding our way to the quiet of the press room proved to be more of a hurdle than originally...

Here we are once more, blogging away after a very interesting second keynote by VMware CTO Stephen Herrod, delving a bit deeper into the actual changes being pushed into different levels of the software. At this point, the amount of information available might actually fill up an entire article, but alas, time constraints force me to keep this...

The Istanbul cores are the same as those that can be found in the AMD's latest Shanghai CPU. But the "uncore" part of Istanbul is more interesting. By now, you have probably heard about AMD's "HT-assist" technology, a probe or snoop filter. Every time a new cacheline is brought into the L3-cache of for example CPU 1 on the current Shanghai Platform, a...

Seeming as how virtualization is a technology that is still expanding exponentially, and our research is not of the kind that drops a subject once the novelty has worn off, the Belgian IT department of Anandtech is once again attending VMworld Europe, with high hopes of greatly improving our knowledge on the vast amounts of fields virtualization has...

Last Friday, AMD has given a good answer to the approaching Intel Xeon Nehalem EP thunderstorm. AMD demonstrated to a handful of journalists (Charley and Scott) an up and running dual and quad socket Hexacore Istanbul system. Istanbul, which should be ready in the Autumn of this year, is basically a six core version of the current AMD Opteron...

A dramatic turn of events is the best way to describe what we'll witness in a few weeks. But let us first talk about the current situation. As we pointed out in our last server CPU comparison, AMD latest quadcore Opteron was a very positive surprise. Sure, you can show a few server benchmarks where the Intel CPU wins like Black Scholes or some exotic HPC...

We were quite amazed, even slightly suspicious, when HP and Fujitsu-Siemens Published their SAP numbers. These numbers showed that the newest Xeon X5570 (Nehalem EP) series offer an enormous performance boost over the Xeon X5470 (Harpertown). After all, an almost 100% improvement at a slightly lower speed (2.93 GHz vs 3.3 GHz) is nothing short of...
