An 8-core 16-thread enterprise Xeon® processor has 2.3B transistors in 9M 45nm
CMOS. The I/O links use per-lane TX and RX compensation to enable operation up to
6.4GT/s. Vertical and horizontal spines keep the uncore clock skew under 19ps before
engaging the compensation. Core and cache shut-off techniques are used to minimize
leakage.

3.2 A Family of 45nm IA Processors

A family of next-generation IA processors with up to 8 cores, enhanced Core™
microarchitecture, 3-level caches and 2-way SMT is implemented in 45nm high-κ
metal-gate CMOS. The family has a coherent point-to-point link and integrates memory
controller, power-management microcontroller and power-gate transistors and scales
from sub-10 to 130W in mobile, desktop and server applications.

A monolithic 6-core Xeon® processor has 1.9B transistors in 9M 45nm CMOS with a 9MB
L2 and 16MB L3 cache and exceeds 1M transactions/minute TPCC in 8-socket
configuration. The FSB I/O circuits are implemented in the center of the die to reduce I/O
latency. A low-leakage process variant with cache-sleep and shut-off modes enables
low-power 6-core 65W and 4-core 50W variants.

6 core那个是Dunnington吧？三颗上代架构Penryn-3M核心和16MB L3拼一起弄出来的。
看起来Nehalem-EX(Beckton)确认是原生8核心了？2.3B相当于三颗Bloomfield了啊，不知道塞进去多少缓存。

后藤说好像是24M吧
不过Xeon MP肯定相对桌面增加了新的特性，可能用去一部分晶体管；内部和外部的互联，包括更多的QPI连接，四通道的FB-DIMM控制器，都将用掉很多晶体管

另外，不知道现在还是不是和安腾同插座了。

你能肯定RAM用FB-DIMM? 听说BUFFER都移到板上去了,包括TUKWILA用的板.
