性能同功耗都唔錯
作者: akiralee 時間: 2013-9-22 12:13
待正式driver出的時候，估計性能還可提升10-15%左右吧？

如果AMD的CPU可以好似GPU咁生性就好了

EPIC WIN
vcfirstben_II 發表於 2013-9-22 15:52
Is it? I don't think the win is big enough personally. nV will have an un-cut version of GK110 waiting.
However, since this generation is still limited by 28nm, I will forgive AMD.

我想像唔到 AMD 點整 2 GPU in 1 Board 既東面出來了。

「攬炒」係指同對手玉石俱焚
我諗你係想講NV已經全軍覆沒了
如果硬係要用地道d o既廣東話黎型容NV而家o既情況， 應該係"杏仁加橙皮"*會比較貼切

話時話， 咁o既價位， 點解唔試埋7990呀？ 如果7990性價比高過黎緊o既Hawaii， 可以趁而家仲有貨狗衝張返黎wor

夏惠姨有冇乜功能上既殺著呢

Finally gaining a slight edge is no way epic IMO.
It might help pushing Titan's price a bit lower, but it is nothing epic or really game-changing here.
If they are outclassing everybody by a way lower price point like USD199~299 (Just like RV770)
That can be called epic.
I'm not blaming ATI, but it is a misuse of word.
It is hard to be epic in today market.

Is been a long time since we see a completely new SKUs from both camp. Gamers have been hungry for long to see a new king. So I don't blame them.
The truth is, both camp are limited by the 28nm process. Without a new process, is very hard to be, like what you said, "epic". The win is not big. That's for sure. But given the fact that it is still on 28nm process, I guess is understandable and I will give AMD some leeway.
I do hope for some GPGPU refinement tho. The target should not be only Titan now, but also Intel's Knight Corner. We all know high end gaming market is no longer blooming.

Yep, I don't expect it to be epic neither.
The only thing came close to epic in last 2~3 years is the first release of GK104 IMO
But that's new architecture on new process with a unexpected targeting
The development cycle slowed down enough to be "expectable" nowadays.
Just like CPU, Epicness is hard to find.
And for GPGPU...It might take some more time to mature out, I just don't see it as ATI's territories at all until GCN
BTW, the PCB kinda reminded me of GT200 w/o IHS, I'm not sure why.

performance per die area 有 10% 以上的話就已經 epic 了

Tahiti: 352 mm^2
Hawaii: 425 mm^2 (Calculated by AnandTech)
Hawaii is ~20% bigger than Tahiti.
May be you are right. (If whatever results posted on the first page is legit.) But, I guess I may be spoiled by previous GPU launches.
We will know more soon. (AMD GPU 2014: Sept. 25, 2013 at 3 p.m. EDT)

R7-270
1080p and 1600p
在7870和660Ti之間
平均Benchmark：
GTX 760 →100%
GTX 660Ti →94.5%
R7 2_0 →89.7%
HD 7870 →82.4%
每瓦效能：
GTX 760 →100%
GTX 660Ti →108%
R7 2_0 →119%
HD 7870 →114%
在1600p是完秒7870的每瓦性能
小學算數
給你跑分和每瓦效能了
自己去推R7 2_0幾瓦吧
現場大螢幕......
這邊有喝不完的雞尾和Heineken light啊

回復 3# 唐賓南紀念中學
CPU普普通通是正常的, 知道無法與INTEL打, 唯有從ARM+GPU來打. AMD的第一個做法,可能就是把ARM整合在GPU上作分配資源用 (GCN). 因此, 為何只要用上HD7000系列後, 為何CPU不多做事. 我自己買了7970後, 第一件事就是試另類的, 就是把7970變成"礦工". 過程中,CPU沒有特別工作, GPU就嘗試找有用"材料",CPU就只聽GPU的情況.
注: GPU仍然要向CPU查問資源位置, 確定後會由GPU上的ARM部份處理資源其要求, 情況會用ARM傳情況予CPU. 因此可以好獨立操作.

Depend on your perspective, I guess. If you set the target as Tahiti, Hawaii does show significant improvement.
