Shrinking the Xeon with Westmere-EX

 AnandTech got their hands on four of the the brand new 32nm Intel Xeon X7 4870, 10 cores clocked to 2.4GHz; perhaps a delayed 'Tick" but a tick nonetheless.  Not only did they test the new chips they also had a chance to test it with Load Reduced DIMMs (LR-DIMM) as opposed to the old Fully Buffered style (FB-DIMMs) we were used to in days gone by.  That spells higher capacity which is good considering the testbed they used can support up to 2TB of RAM to keep the 4 CPUs fed.  This is a high end server part, not really competeing against AMD as a similar Opteron system would cost about 1/2 as much with performance reduced about the same as well.  Check out this beast, but keep in mind a single CPU will set you back more than you paid for your whole system.

"Only one year later, Intel is upgrading the top Xeon by introducing Westmere-EX. Shrinking Intel's largest Xeon to 32nm allows it to be clocked slightly higher, get two extra cores, and add 6MB L3 cache. At the same time the chip is quite a bit smaller, which makes it cheaper to produce. Unfortunately, the customer does not really benefit from that fact, as the top Xeon became more expensive. Anyway, the Nehalem-EX was a popular chip, so it is no surprise that the improved version has persuaded 19 vendors to produce 60 different designs, ranging from two up to 256 sockets."

Xeon powered 2U server room beauty

 When The Tech Report were asked to review the new Dell R810 2U server they jumped at the chance.  Inside lies dual octocore Xeon X7560s, 128GB of DDR3  (of a maximum 500GB), four SAS 6Gbps drives (which they swapped for Vertex EX SSDs) and a pair of 1100W PSUs.  It is impressive to see all that shoved into a 2U rack but Dell went further with internal SD card readers for easy HyperVisor use, external LCDs to display realtime hardware and software data and a casing much more attractive that you usually see in a server room.  The performance compared to a dual X5670 system varied so you should probably read the review before you go spending $23,000 on the server.

"Intel's eight-core Nehalem-EX processor and Dell's R810 chassis combine to form a new class of 2P server, with huge memory capacity at a lower price point."
