超频是以发热量为代价的。
总之,i7 820QM 720QM 620M 620LM 620UM都只能turbo 一个核心。
i7 920XM可以turbo 2个。 |

i7-920XM 4322/11916 1:2.76

i7-720QM 3334/9559 1:2.87

core2 X9100 3834/7299 1:1.90
有意义么?
i7 i5移动系列只是单核能力加强了。
i7-920XM 多核应用只比QX9300快 9%,相当于 2.76GHz 的旧核心4核
(超2核,再加上超线程提高6%的性能:[3.2*2+2.0*2]/4 *1.06 ≈ 2.76 )
而i7-820QM 多核应用比Q9100慢 1.2%,相当于 2.20GHz 的旧核心4核
(超1核,再加上超线程提高6%的性能:[3.067+1.733*3]/4 *1.06 ≈ 2.20 ) |

The Dell Studio XPS16 has Intel174; Core8482; 2 Duo P8700 (3MB cache/2.53GHz
/1066Mhz FSB).
If I upgrade the monitor of Studio 15 to 1080p, they are almost the same
price, around $1060. Sudio XPS 16 is very popular and has very good reviews.
But the Studio 15 has i7 processor, and only one review.
Which one should I choose? Thanks a lot.

W510的CPU最低是i7-720QM, 已經比T510的最高CPU i7-620M強了。
W500的CPU選項與T500一樣,而T500的CPU不如T510的(i5-540M性能就相當于T9900了),就更不
要說W510了。
屏幕,FHD LED屏遠勝W500的 WUXGA,無論亮度還是色域。
最重要的突破點是W510可配顏色傳感器和觸摸屏,有四條內存插口,所以,W510遠勝
W500.

Windows7的那个评测,不全是按测分来的。
HDD RAID0 170M/s读170M/s写,评分还是5.9,
再慢再差的SSD,一般也会评分>5.9
CPU有超线程就硬加分,即便实测比其他没超线程的CPU慢,但是CPU得分要好看。
典型的i7-720QM多核性能就比Q6600慢,但是得分要好不少。
所以Win7评分就是一个参考,没实际意义,除了可以BSO. |

b*****a 发帖数: 297 | 45 i7 MBP最高配其实就是i7-620M,双核的,和T510一样。多核性能并不如W510的最低配
四核i7-720QM.
W510的显卡是专业显卡,核心和GT330M是一样的,但是显存大得多:1GB vs 256MB/
512MB.
MBP因为没能搞定散热,显卡的核心是降频使用的,实际上比正常的GT330M差。因为散
热,MBP就更不敢上4核CPU了。MBP VS W510, 显卡和CPU都不行,凭什么笑傲W510性能
一般?
再说,W510还有高配,高配CPU和屏幕。
btw:难道MBP就不沉么?
其实,拿独立显卡的T410s来装雪豹MacOSX,就好多了。
对比之下,苹果是在痛宰用户啊,不然,就那点硬件,也配卖高价?核心还是在OSX.
当然,Thinkpad用OSX是盗版和侵权。
势。 |

g******z 发帖数: 5809 | 46 嗯,720QM大多数时候不如620M
单核明显620M强悍 3.33G vs. 2.8G
双核也明显620M强悍 3.06G vs 2.4G
只有720四核心的情况 3.06x2 vs 1.73x4 只差 6.92-6.13=0.79G
显卡关键看实际速度。果子本本没用过Quadro,所以不会有什么提升
从厚度上看,如果果子能做那么厚,多几个散热口,也能做到一样的散热.MBP15重量还
是略轻。
W510高配价格就上去了。上个RGB LED啥的。(似乎现在没有这个选项)
W510用来跑果子系统真没有优势。USB 3.0和WiMax啥的都没驱动。
这点硬件是没什么价值。但是和前代相比性价比还是进步了些。
果子卖得是壳子(包括一些设计)和牌子。 |

T510的显卡确实不如T500的,但系统架构已经换代,T9XXX是高端的上一代,为什么不
拿i7出来比呢?
51NB的结论,一般T9900差不多可以和520相提并论,540和620基本上双核无敌,你要是
拿Q和QX来说那么请移步W510的 i7 720qm/820qm/920qxm/940qxm去 |

问题的关键还是功耗,功耗不降下来都是废柴。
可以这么理解,单个核心的主频增加了,缺省的发热量增加了,但是要维持TDP不变,留给内部超频的发热量反倒减少了,所以总性能随主频提升反下降。只有放置在极低温环境,例如,水冷或者泡在液氮里,完全不用担心发热量大小时,940XM才在性能上全面超920XM。 |
