Lawrence Lee 于2008年9月份得到了正式上市版本的DG45FC,他做了部分测试比较。正式上市的最小版本号是AA E27730-305,9月底实际批量销售的已经是AA E27730-306版本。而此前关于DG45FC的传闻大多只是基于Intel DG45FC 工程样品的展览,那些传闻者并且没有实际应用(未提供外界试用)。从图片可以看见,9月之前的工程样品与9月中旬开始实际上市的产品有明显的不同,后者作了较明显的设计更改,并且产品的BIOS 及驱动均作了更新。
Lawrence Lee 完成应用测试后的总结:
Overall we are impressed with the G45 chipset. While the X4500 IGP represents only an incremental increase in both 2D and 3D performance over the G45, power consumption was much improved. We would love to see Intel make G45 their defacto chipset rather than the woefully outdated and inefficient G945 chipset used in the desktop versions of Atom boards. The G45 chipset would have made Atom-based solutions truly killer. The potential power savings would improve battery life in mobile devices and the vastly superior graphics subsystem would help make up for the Atom's lack of processing power when playing multimedia.
Lawrence Lee 写道:
“总而言之,G45 芯片组给我们留下深刻印象。虽然G45 系列的X4500 IGP(整合图形处理器) 在2D 和3D 方面表现着性能提高,功率消耗却大有改进。我们很高兴看见Intel 使得他们的G45 芯片组远胜于桌面Atom主板所使用旧的、低(能源)效率的、可怜的G945 芯片组,G45 芯片组将成为Atom 主板系统真正的杀手。潜在的:G45 的节能性能会提高移动设备的电池使用时间,并且在多媒体播放方面高级图形子系统会有助提供Atom 所没有的性能”。
However a motherboard is not just a chipset - the manufacturer is key in how the finished product ultimately ends up. While the DG45FC is more of a consumer/enthusiast product, it is still mainly a business-oriented Intel workhorse. The BIOS is completely locked down, and the fan control system is primitive. We should also note that the board does not support quad-core or older high TDP dual core CPUs - this may be a power regulation issue as there might not be enough room on the PCB to fit all the electrical components required to handle a high power processor.
Despite these quibbles, for a mini-ITX mainboard, the Intel DG45FC probably has no current equal. It has a vast feature-set including 4 SATA ports, gigabit ethernet, and eSATA, and a wealth of digital outputs. Its $130~150 price-tag is quite reasonable - mini-ITX gear generally goes for a large premium, but the DG45FC is only marginally more expensive than equivalent mATX motherboards. Paired with a Wolfdale processor and an efficient power supply, the DG45FC is an excellent choice for a powerful yet energy-efficient mini PC.
Lawrence Lee 写道:
“尽管有些微词,而作为一款mini-ITX 主板,或许Intel DG45FC 当前没有对手”。
“作为一台功能强大的并且能源效率优良的 mini PC,DG45FC 是一个极好的选择,配置一个Wolfdale (双核)处理器和一个高效率的(80 Plus)电源”。
(笔者注:国内某个内资企业主板供应商虽然于8月份发布了780G mini ITX 主板消息,并且预计定价远远高于 DG45FC,但目前国内零售市场上尚未有货)。
这里顺便提醒国内DIY 爱好者,如果你想购买真正的80 Plus 认证合格的电源产品,那么建议你首先浏览 www.80plus.org,核查产品型号,而不是轻信那些国内某些鱼目混珠的商业文字宣传,避免成为冤大头高价买来 伪80 Plus 电源产品。
Aaron Brezenski 在8月14日谈到:
I understand the reason: the standard COPP protocols that all of these players use do not support the use of repeaters (even though our competition appears to be ignoring these strictures), and the software players don't yet use OPM (which does support repeaters). This is all very well and good, and we're probably in the right on this regarding supporting the spec: but the end user doesn't see this. They see our competition's graphics working flawlessly with their software player on their shiny new Onkyo or Yamaha receiver, and Intel's failing. The successful 7.1 LPCM tests I mentioned above were done using gray-market AACS-stripping software.
The G45 is really the perfect home theater chipset (at least until such time as it is superceded by one which can transmit Dolby TrueHD and DTS HD-MA... that's a topic for another time) and the motherboards we're putting out using it are elegantly designed (the DG45FC is a thing of beauty).
Aaron Brezenski 在8月15日谈到(有人在他的Blog 发表读者意见之后):
Next, the repeater mode issue is, as I suggested above, being worked by our teams. My understanding after speaking with some of the Intel chipset marketing and engineering folks is that Intel is working with the key media player vendors to support repeater mode. The fact that it's not there today does not imply the hardware is incapable in any way, just that the support for it is a work in progress. I thought I'd made that clear but I'm hearing rumblings it's being touted as a weakness in the chip based on my comments. Not so! My understanding, based on some feedback I've received internally, is that players with this enabled will be forthcoming shortly. So while my statements are not inaccurate, my impatience prompted me to post early on an issue that is already being fervently worked. I'm glad to hear it.
Aaron Brezenski 在9月8日接着谈到:
Gary Key of Anandtech points out that a newer release of Corel's WinDVD fully supports repeater mode for Blu-ray on Intel Graphics, and postings on Arcsoft's user forum imply that an update to their TMT Blu-ray software is forthcoming as well. So as I pointed out back in August, things are already improving on that front-- I know who's responsible and shan't use their names here, but I will say you guys did an excellent job! The home theater enthusiast community thanks you! Already G45 is being recommended on the AVS forum by the author of the very thorough and influential "Guide to Building a HD HTPC" thread.
Aaron Brezenski 在8月15日谈到(这些文字出现在9月正式版本的DG45FC 之前): 24p is a mixed bag, as some personal messages I've received have stated, and is a bear to get working on any system, not just Intel's. We have been in a 60Hz world for so long that matching the 24fps film rate is hard for even hard core graphics guys to wrap their heads around. There are entire threads dedicated to getting stutter-free playback on Blu-ray on Audio/Video Science forum. It's a non-issue for most folks (I placed it in The Bad, not The Ugly, for a reason), but a sticking point for enthusiasts, who have the TV sets to take advantage of it. It wasn't working on previous chips; I'm confident it will get fixed, it's just a question of when.
Lawrence Lee 先生用专用的温度仪测试了DG45FC:
To test the cooling on the board, we lowered the CPU cooling fan's voltage to 7V to reduce the amount of top-down airflow the nearby components received. We then stressed the system with Prime95 and ATITool and whipped our our handy IR thermometer to check the results. After about 20 minutes of load, the hottest point on the northbridge heatsink registered 71°C, while the southbridge heatsink read 72°C. Neither reading is that high compared to other boards we've tested. Most of the board's MOSFETs remained quite cool throughout testing as they were close to the CPU socket and probably received enough top-down cooling.
尽管Lawrence Lee 先生测试的南桥温度只有72度C,但如果采用非常小型机箱,我个人建议为南桥添加一块铝散热片,毕竟那只有5元或10元人民币零售价格,散热片底部必须有高品质的3M 导热胶纸(导热、并粘接可靠耐久),绝对不可使用劣质胶纸固定散热片,避免引起安全事故。ICH10R 的TPD 仅仅4.5W,但还是有少许热量。
