IntelXeon E5-2660和IntelXeon E5-2665有什么区别_百度知道
IntelXeon E5-2660和IntelXeon E5-2665有什么区别
我有更好的答案
1.IntelXeonE5-2665（至强）是2012第一个季度才推出的新一代中小型服务器专用CPU，采用SNB-EP架构（和COREI73960X,COREI73820是相同的架构）8核16线程，主频2.4GHZ，支持TURBO到最高3.1GHZ，20MBL3共享缓存32NM制程，功耗115W，内建4通道内存控制器，支持最高750GB内存，采用庞大的LGA2011接口。2.这款CPU在美国的零售售价为大约1400美元。这款CPU在中国国内极少有零售（基本可以说没有），而是搭配服务器一起销售。基本上来说，按照楼主所说的淘宝上的价格来说应该是人民币9760元的是比较可信的（1500元？买8核16线程的I7级别的CPU，这个价格也太离谱了吧）。3.ES是工程样品版，一般来说都是主频无法达到标称频率，或者配置不全仅仅作为各大媒体测试用的CPU.4.低温版，完美版！？不知道是什么东西，应该都不是正品
看步进，如果一样就是主频增加，性能增加一点点

Conclusion
The massive 416 mm² large chip contains no less than 2263 million transistors. Each generation of Intel and AMD server CPUs seem to get a bit larger as you can see below.
The Xeon /5600 and E5-2600 package on top, the Opteron
So how does the new Xeon compare to the older Xeons and the latest Opterons? Let's take a look at the paper specs:

Die Size (mm²)
The new Xeon comes with a huge die, and with its ring interconnect and improved RAS, it starts to look more like a successor of the Westmere-EX than the Westmere-EP Xeon. In fact the ring of the Xeon E5 is more advanced: it has a PCIe agent, PCU and IMC on the same ring as the 8 cores.
The massive die, the two extra cores, the integration of the PCIe controller and no competition in the high-end have made it easier for Intel to justify a price increase. The Sandy Bridge EP is somewhat more expensive than its predecessor, as you can see in the table below. The first clockspeed mentioned is the regular clock, the second the turbo clock with all cores active (most realistic one) and the last the maximum turbo clock.

The Xeon E5-2690's somewhat out of the ordinary TDP (135W) is easy to explain. With a very small TDP increase (+5W) Intel's engineers noticed they could raise the clock of the best SKU with another 200 MHz from 2.7 GHz (130W) to 2.9 GHz. The E5-2690 was more or less a safeguard in the event that the Interlagos Opteron turned out to be a real &Bulldozer&. As the Opteron could not meet these expectations, the high performance of the 135W chip allows Intel to ask more than $2000 for its best Xeon EP. Which is quite a bit more than what the best Xeon EP used to sell for so far ($).
Since the new Xeon has two extra cores and integrates the I/O hub (IOH), it is understandable that the TDP values are a bit higher compared to the older Xeon.
How does these new Xeon SKUs compare to the Opteron? See below.

Let's start with the midrange first, as the competition is the fiercest there and these SKUs are among the most popular on the market. Based on the paper specs, AMD's
and Intel's 2640 and 2630 are in a neck-and-neck race. AMD offers 16 smaller integer clusters, while Intel offers 6 or 8 heavy, slightly higher clocked cores with SMT. And while we did not receive a Xeon E5-2630 for benchmarking purposes, we were able to quickly simulate one by disabling the 2 cores of our Xeon 2660, which gave us a six-core processor at 2.2 GHz with 20 MB L3-cache. This pseudo-2660 should perform very similar to the real Xeon 2630, which is clocked 4.5% higher, but has 5 MB less L3-cache.
Meanwhile in the high performance segment we'll be comparing our six-core 2660 with the Opteron 6276. The CPUs in this comparison aren't going to be in the same price bracket, but as the AMD platform is typically a bit cheaper the 2660 and the Opteron 6276 end up having similar total platform costs. Otherwise for a more straightforward comparison based solely on CPU prices the 2660's closest competitor would be the Opteron 6274. We don't have one of those on hand, but you can get a pretty good idea of how that would compare by knocking 4% off of the performance of the 6276..
Finally, for the &Power Optimized& market there seems to be little contest over who is going to win there. Intel's chip is a bit more expensive, but it offers a much lower TDP, just as many threads, and a higher clockspeed. Considering that the Intel chip also integrates the PCIe controller, it looks like Intel will have no trouble winning this battle by a landslide. Fortunately for AMD, this review is mostly about the more popular midrange market.

Ah man, the 2630L error totally got my hopes up. 8 cores for $662 would be very reasonable.

How do celebrities keep fit and be always on top? Simple, complete with exercise and of course the right diet. In Hollywood it every day a new diet is devised that promises weight loss in a short time and a fabulous body. From the fasting diet to that of the Paleolithic, up to that of the blood type, the stars follow them a bit 'all.

...just got bulldozed. And this isn't even on the 22nm 3D transistors they're launching next month, it's like they just got a dizzying punch and know the KO punch is coming.

It'll probably be awhile before the Ivy Bridge Xeons are out.
Kjella - Tuesday, March 06, 2012 -
Of course, I'm guessing Q1 2013 before we'll see those but we already know from all the leaked SB -& IB details roughly what SB-Xeon to IB-Xeon will be like. All AMD has on their roadmap for 2013 is the &Abu Dhabi& with the &Piledriver& core promising 10-15% performance boost but still on 32nm. So you can see the punch coming a year away, but I don't think AMD has the capability to do anything about it.

如题，搞不懂。。。用来玩使命召唤的，求大佬帮助...
登录百度帐号拿E5 2660 C2玩游戏和拿这个玩游戏哪个好？
按时间排序
E5 2660是服务器CPU，家用CPU，游戏只支持4核，依赖频率工作。你在多的内核都不工作的。超频吧，上个好散热器，上到3-3.5G，性能就上来。打游戏，还是选I5 7500更强了。
