结论：
A week ago, this conclusion read a lot differently. The Radeon HD 4770 was set to be priced at $99 and the card trounced the Radeon HD 4830 selling for $10 less on the street. At the same time, it boldly stood up against the Radeon HD 4850 and GeForce GTS 250 averaging $30 more (note that the 1 GB GTS 250 is an additional $10 to $20 more than even the Radeon HD 4850). Thirty bucks isn't much money, but when you're talking about $100 graphics cards, that's a significant chunk of value. It almost seemed too good to be true.

Well, you know what they say about too good to be true. At the last minute, ATI changed the price to $109. Nothing about the card's performance was altered. It remains a fast little board with good power consumption numbers. But it lost that "in your face for under $100" sass. For 20 bucks less, you can still pick up a Radeon HD 4830 (a card that still performs very well). Or, for 20 bucks more, you could grab the Radeon HD 4850 or a 512 MB GeForce GTS 250 (cards that are generally faster). The 4770 is now priced appropriately, not spectacularly.

When Nvidia launched its GeForce GTX 275, we were quick to recommend it to enthusiasts lusting after the GTX 285, but hesitant to spend so much money on a graphics upgrade right now. Today, we’re doing the same with ATI’s Radeon HD 4770. If you had your eye on a Radeon HD 4850 or GeForce GTS 250 at $120-$130, this card will paint a very similar performance picture for $110. Yes, if you chase the lowest price and factor in mail-in-rebates, the Radeon HD 4850 and GeForce GTS 250 come very close to this card. But on average, those boards are more realistically $120-$130 offerings. And if that's the game you play, ATI is also claiming a mail-in-rebate will push the 4770 under $100, too.

Even as Nvidia’s CUDA and PhysX technologies gain traction, gaming performance remains the principle impetus for enthusiasts to upgrade their graphics cards. The Radeon HD 4770 won’t play all of your games smoothly at 1920x1200 using high quality settings, but it can drive that configuration in a number of them.

The one value-add we now see disrupting the performance-only approach to buying graphics is Nvidia's CUDA. We’ve been working on a roundup of CUDA-enabled applications all month, and it’s becoming clear that general purpose GPU computing is very much within the reach of the mainstream right now. ATI is trailing behind in this initiative, and the lack of applications optimized for the company’s Stream technology does weigh in as a negative.

However, we have to trust that the Tom’s Hardware audience is informed enough to know whether or not they have a legitimate outlet for employing CUDA and, to a lesser extent, PhysX. GeForce 3D Vision, the third pillar in Nvidia’s value-add message, simply isn’t viable given the performance of these mid-range graphics cards. To really enjoy that, you’ll need something more powerful.

At $99, the Radeon HD 4770 was an award winner. At $109, it remains a good demonstration of 40 nm manufacturing at work and, as mentioned, a recommended alternative to the Radeon HD 4850/GeForce GTS 250 for budget-crunched gamers. Well-played ATI, well played.

英文版的看得我好类。
确认了两点，1，4770确实是AMD官方定位109的，2，现在不是入手的好时机

b22sun

性能还真比 4830强～～～

消息太多太杂，我也无法分辨了，根据这篇评测，确实是AMD调价的。
官方不可能在2天内调整2次价格吧？
所以调回99可能是商家的个人行为。
当然我这个假设是在本文属实的基础上的。

性能还真比 4830强～～～

就现在看来性价比不如4830

Michal

全默认的话应该这成绩差不多吧，据说40nm超频好，反正4830清光前不可能有实惠的4770

tangcw2002

800SP的4830就跟4770一样了，4770不降价到500，我看玄。

NV也是时候拿点诚意出来消灭4770了，比如让马甲GTS250下降到699价位。

性能还真比 4830强～～～
b22sun 发表于 2009-4-29 14:15

是比640sp的4830强! 4770也是640sp,频率还高很多,不强才怪.不过比4850和800sp的4830,还有差距

clus

重点在于最后一句！ “如上所述，4770建议推荐给那些关注着4850，G250但又囊中羞涩的FANS,干得好，ATI, 干得好！”

btren

看的迷糊。。。。

ljlxl

价格如果是5xx的话，还差不多

labird

Tom's的编辑们知道有800sp 的4830这种怪胎么

akcadia

如果同样价格，性价比还是不如4850或者250啊，

4770比800SP的4830稍微强一点的，部分测试中比4850强，你看看上面的测评

Iota

akcadia 发表于 2009-4-29 15:49

比250强多了，Tom's不厚道，竟然拿个1G的250来比，不仔细看还不知道吧

Asuka

250和4850是一个性能

4770默认频率会强过4850吗?

k9999

功耗和发热会成为部分人选择它的理由的

Athura

比4670空闲和满载都多了20w的功耗...要是功耗没怎么增加就好了，就算空载功耗没怎么增加也好啊。
