In this month intel presented only the desktop processors bloomfield, in the architecture which revealed numerous advantages, capable of being opened only within the server platform.
In the first place, its necessary to note the integrated memory controller with NUMA support and QPI bus, which will replace the classical FSB, considered as bottleneck for intel server platform.
In the desktop systems on base Of intel x58 the QPI bus connects only the processor with the north bridge, and it barely influences the speed, but in the server systems situation will change.
This week appeared the frequency characteristics and prices of the server processors series xeon 5500 (Nehalem-EP) and Xeon 3500 (Nehalem-WS), which will be released in the first quarter of the following year. We start from elder processors, capable of working in pairs:
Xeon w5580 (3.2 GHz) - > $1600;
Xeon x5570 (2.93 GHz) - > $1386;
Xeon x5560 (2.8 GHz) - > $1172;
Xeon x5550 (2.66 GHz) - > $958;
Xeon 5540 (2.53 GHz) - > $744;
Xeon e5530 (2.4 GHz) - > $530;
Xeon e5520 (2.26 GHz) - > $373;
Xeon e5506 (2.13 GHz) - > $266;
Xeon e5504 (2.0 GHz) - > $224;
Xeon e5502 - > $188.
The Last processor, Xeon e5502, have only two cores, and rest include four physical cores. For the single-processor systems will be proposed the following versions :
Xeon w3570 (3.2 GHz) - > $999;
Xeon 3540 (2.93 GHz) - > $562;
Xeon w3520 (2.66 GHz) - > $284.
They will also have four core, and they will preserve the design concept LGA 1366. The server versions nehalem for systems with processors number from four and more will be presented only at the end of 2009.
Company AMD expects to present the processors istanbul with six core at the end of 2009, and in 2010 AMD is ready to increase the number of core to twelve. At the same time server processors AMD will obtain support to DDR 3 memory and new design concept socket g34.
