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."
