Intel's next-generation server processing units were released in the first half of March (2012), but they aren't the only ones of their kind that the company has planned.
In fact, the Xeon E5-4600 line should show up soon, in the second quarter in fact, which has just begun, more or less.
The company hasn't formally released the specifications of the products, but that hasn't stopped leaks from doing it instead.
In fact, CPU World has pretty much every bit of relevant information set up in a nice little list.
There are eight Xeon E5-4600 chips, with four to 8 cores, cache of 10 to 20 MB and a TDP of 95W to 130W. All of them fit socket 2011 motherboards.
To start off, the Xeon E5-4603 is a quad-core chip (8 threads) with a 2 GHz clock speed, 10 MB cache, DDR3-1066 support and a 95W TDP.
Xeon E5-4607 is a six-core chip with 2.2 GHz clock speed, 12 threads, 12 MB cache, DDR3-1066 and a 95W TDP.
Xeon E5-4610 similar to the one above, but it has a 2.4 GHz clock, 15MB cache and DDR3-1333 memory support.
The last 6-core chip lacks multi-threading but has a 2.9 GHz clock, 15 MB cache, DDR3-1600 memory and a 130W TDP.
The other four units are 8-core chips, starting with Xeon E5-4620, a 16-threaded, 2.2 GHz, 16 MB cache, 95W product with DDR3-1333 memory support.
Somewhat stronger is E5-4640 (2.4 GHz, 20 MB cache, DDR3-1600) and the Xeon E5-4650 goes even further, to 2.7 Ghz (16 threads) and a 130W TDP.
Finally, the Xeon E5-4650L is an 8-core, 16-thread invention with 2.6 GHz clock, 20 MB cache, DDR3-1600 memory and a TDP of 115W.
The Intel Xeon E5-4600 server processors are primarily intended for 4-socket servers, although they shouldn't have any trouble powering dual-socket and simple ones if necessary.
