Getting down to business then, AMD has clearly positioned the 290X as a price/performance monster, and while that’s not the be all and end all of evaluating video cards it’s certainly going to be the biggest factor to most buyers. To that end at 2560x1440 – what I expect will be the most common resolution used with such a card for the time being – AMD is essentially tied with GTX Titan, delivering an average of 99% of the performance of NVIDIA’s prosumer-level flagship. Against NVIDIA’s cheaper and more gaming oriented GTX 780 that becomes an outright lead, with the 290X leading by an average of 9% and never falling behind the GTX 780.

...

But with that said, although the 290X has a clear grip on performance and price it does come at the cost of power and cooling. With GTX Titan and GTX 780 NVIDIA set the bar for power efficiency and cooling performance on a high-end card, and while it’s not necessarily something that’s out of AMD’s reach it’s the kind of thing that’s only sustainable with high video card prices, which is not where AMD has decided to take the 290X. By focusing on high performance AMD has had to push quite a bit of power through 290X, and by focusing on price they had to do so without blowing their budget on cooling. The end result is that the 290X is more power hungry than any comparable high-end card, and while AMD is able to effectively dissipate that much heat the resulting cooling performance (as measured by noise) is at best mediocre. It’s not so loud as to be intolerable for a single-GPU setup, but it’s as loud as can be called reasonable, never mind preferable.

Similarly, AMD’s Radeon R9 290X isn’t the most expensive or luxurious graphics card out there. It leans on an old cooling solution that we’d like to see improved, and it’s wrapped in a plastic shroud. There are a few things we think AMD could be doing better, and we’ll get into those. But when it comes to gaming performance, this card has little trouble trouncing its primary competition, GeForce GTX 780, and even Nvidia’s GeForce GTX Titan in a number of cases—both of which are substantially more expensive boards.

Let’s get the bad out of the way first. AMD is pushing its Hawaii GPU pretty hard in order to achieve the performance it’s getting. Although the R9 290X is rated for 1000 MHz, the right load will get Hawaii up to its 95 °C limit pretty fast. From there, you have to rely on the right fan speed to keep that clock rate up.

粒chip推到咁盡, 會唔會多RMA

不過R9 290應該會更加好玩

Evolution

想買280 但幾時有bf4送

A 記為左贏 推到咁
又平賣, 整 RMA 賠死

好大機會bin好多R9 290, R8 / R7公公板

無 R8
可能 R9 290 玩 best perf/watt

Hawaii好難只得2 bin, 尤其係R9 290X係咁top bin的時候
R9 290食唔哂其他貨

290 + 290X 食到一堆啦。良率又唔似會太差。
仲有新 FirePro 堆貨呢。最衰咪搞 R9 285X, 32 CU + 4 prim/clk

Bonaire 跑 1Ghz/6Ghz 咪又係得一個 SKU

Hawaii同Bonaire die size差咁遠, 點可以撈埋一齊, Titan都bin 3個grade啦

所以Hawaii幾乎肯定會攪3個bin (唔計FirePro)
只係叫咩名

參照 Tahiti LE 既歷史...

我下個月買 R9-280X

Fire Pro (Apple Mac Pro) 個兩隻 SKU 係 HD7870 / HD7930 黎...唔係 Hawaii based

亂up  一下

$4.5k - R9 - 290X  512bit 64ROP        ($549 USD)
$3.5K - R9 - 290   512bit 48ROP        ($499 USD - TBC , Q4 2013 Christmas season / Q1 2014 )
$3K   - R9 - 280XT 384bit 48ROP        ($399 USD - TBC , Q1 2014)
$2.5k - R9 - 280X  384bit 32ROP

點解會咁諗係因為 A 記有類似作風

上代 GCN family
HD7970 (Tahiti) 奄D => HD7950 => 最後出左HD7870XT/HD7930  (限量)

再上一代 "Northern Island"
HD6970 / HD6950 / HD6930 (Limited Market, 真係有出過)

A 記唔係無前科
一bin 三吃

290X is $549

其實今次粒Chip唔算熱，只係因為Heatsink太雞，如果開到70%，大概70'c @ 3DMark - FSE，只係會嘈到拆天
超頻空間係有，不過應該唔夠傳USD$449 - 499嘅290多
