原来790GX真的很强大

{lol:] 不行不行，功耗低才是王道。

除了3D游戏性能以外，南桥性能、综合商业软件性能、功耗都不行

南桥性能里面只有Network Performance是9300高，别的790GX都是打平或者赢，看贴要仔细。

anandtech的最终评价：

Everyone likes a clean victory; while NVIDIA has the opportunity to obtain just that with the GeForce 9300, there are a handful of lingering issues that cause them to hit just wide of the bullseye. It's a tough conclusion to make; while my HTPC experiences with the GeForce 9300 were fairly flawless, Gary had several issues, and both of us experienced poor memory performance with the platform. Being an early adopter in any case usually means dealing with the lion's share of problems, but with a product that's ready we don't normally have a long list of issues at launch; they generally crop up over time. We knew about the G45 issues and many of them are still unaddressed.

At least the GeForce 9300 issues don't fundamentally cause the platform not to work in a home theater setup, but they are bothersome nonetheless. Given the maturity of the GeForce 8200 as a platform on the AMD side we hoped for more from NVIDIA here, but at least it gives us a glimmer of hope that what we're talking about today will soon fade and we'll be left with an easily recommendable HTPC platform. Because honestly, if these problems are quickly addressed, the GeForce 9300 is as close to perfect as you're going to get for now.

Gaming performance is good enough to compete with what's out there today. The GeForce 9300 is leaps and bounds ahead of Intel's G45, but that's not really a tremendous accomplishment. What NVIDIA has done however is effectively bring 780G-class performance to the Intel platform, which is better than nothing. It's still short of what we want in terms of integrated graphics performance but it's a big step in the right direction.

The HTPC feature set is nearly complete; the only thing we're lacking is the ability to bitstream Dolby TrueHD and DTS-HD MA (both of which no chipset currently supports). Flawless HDMI/HDCP repeater compatibility? Check. Fully functional hardware acceleration? Yep. 8-channel LPCM? Of course. Stutter-free 24p playback? It seems so.

It would be nice to see some more effort put in on the software side, as I mentioned before, to enable configuration of your HTPC without needing a regular computer monitor. I've also been dying to see AMD, Intel or NVIDIA incorporate a real color management system in their drivers to easily enable HTPCs to function as true video processors and not just expensive Blu-ray players.

As far as chipsets with integrated graphics go, NVIDIA's GeForce 9300 won our hearts, I would just hold off on that first date until the kinks get worked out.

引用测试的一句话作为总结：

Good job NVIDIA, here's your crown.

  我坚定不移的认为，Intel应该尽快收购NV
  对两家都是非常美好的

Intel IGP终于不落后AMD IGP，但却是靠别家viagra。。。

性能还好，，功耗确实很强大，，intel的迅驰要害怕了

笑话何必重复两次{blush:]
对了，太平洋的水不是说VC-1硬解吗？怎么没看到？{biggrin:]

美中不足，没有混合动力。白璧微瑕:a)

通过此贴中几个发出790GX真的很强大感慨的回复，可以确认，这个MCP7A确实强大。:lol:

AMD的CPU功耗那么高啊？看到视频都都比INTEL高80W？

goldman948

790gx是因为有128显存才强一点的吧

liutiao3

本来想用性能尽量高的集成嘛
那就780g了
偏偏amd的cpu又太弱
用intel平台吧
intel那集成显卡又差的不是一点半点
不甘愿啊
现在好了
intel的酷睿搭配MCP7A
终于两全了
{biggrin:]

等半年入手，价格就差不多了

很多项目都是越低越好的,看图要仔细

Lower is Better
