兩樣我只信一樣…
如果效能是真的，那價錢絕對是芭樂
如果價錢是真的，那效能就…

Hotclock應該是拿掉了,這個東西被很多人懷疑是造成前幾代產品耗電的元兇

VR-ZONE: NVIDIA to Demonstrate Physx on GK104, Kepler GPU on Friday?

die size如果跟Tahiti差不多且性能真如圖所示的話,我只想到3種可能
1.賣的跟Tahiti一樣貴--->TSxC的28nm良率大概還不是很理想,wafer貴森森
2.賣傳聞中價格--->Tahiti之前的定價還真的是趁沒對手趁機敲一筆
3.TSxC 28nm在2011 Q4很貴,Nvidia有信心預估2012 Q1就會變便宜?

希望是後兩者啦,消費者得利是最讚的 :like:

NVIDIA to Demonstrate PhysX on GK104, Kepler GPU on Friday?
:stupefy: :stupefy: :stupefy:

有消息傳出nVxdia從去年12月開始就沒有再向TSxC下任何GF110(GTX580/570)的wafer訂單
目前供給板卡商的全是手頭上的晶片庫存

GK104真有那麼威?這麼快開始清手上庫存了??? :shock:

GK104若拿掉通用計算的部份，完全是以遊戲卡來規劃，
應該會有相當好的效能功耗比。

NV要加油，不然目前AMD的新卡價格降不下來。

其實兩家的走向是通用運算跟遊戲運算共用絕大部份的單元~

以後就算拿掉通用運算...我想也不會有很大的差別...

剛剛好啦!!

回憶 465 (GF100)系列 到現在還有一堆 庫存 在流通!!
580 570 系列 被自己 GK104 放話給打死!!
對 AMD 產品觀望 對自己舊品更觀望!
典型 打別人 打到自己!

Tom's Hardware Guide- Nvidia Kepler GK104: More Leaks, Rumors on Specifications

Nvidia Kepler GK104: More Leaks, Rumors on Specifications

5:30 AM - February 14, 2012 by Doug Crowthers - source: 3DCenter.org
Nvidia's Kepler goes big with its 1536 CUDA cores, a vast improvement over the Fermi's 512 CUDA cores.

As reported on February 7th, we got a first glimpse of the rumored specifications for Nvidia's Kepler based graphics cards. The leaked specifications were met with both "wow.. can't wait" and "wow... those are so fake why even post" from both sides of the comment fence. Now, we are starting to get more pieces of information on the upcoming Kepler series. Based on information coming out of German-based 3dcenter.org, we may have a clearer picture of the true specifications for Kepler GK104.

Outside of the switch to the 28 nm process, one of the major changes in the Kepler architecture is to allow for more CUDA cores. This is achieved by no longer having shader frequency, just GPU frequency. Each Stream Multiprocessor will contain 96 CUDA cores, unlike the 32 - 48 that Fermi had. This change in layout of the CUDA cores will have the GK104 sporting up to 1536 CUDA cores, which is a big boost from GF110 and GTX 580. The number of texture units have doubled from 64 to 128 on GK104. The GK104 will only have 32 ROPS versus 48 in GF110 but it shouldn't affect performance compared to the Fermi.

Nvidia Kepler GK104:

28nm production at TSMC,
Die size 340mm²
4 Graphics Processing Clusters (GPC)
4 Streaming Multiprocessors (SM) per GPC = 16 SM
96 Stream Processors (SP) per SM = 1536 CUDA cores
8 Texture Units (TMU) per SM = 128 TMUs
32 Raster OPeration Units (ROPs)
Chip clock (top model): 950 MHz
1250 MHz actual (5.00 GHz effective) memory, 160 GB/s memory bandwidth
256-bit DDR memory interface (up to GDDR5)
2048 MB (2 GB) memory amount standard
2.9 TFLOP/s single-precision floating point compute power
486 GFLOP/s double-precision floating point compute power
Elimination of Hotclocks

The GK104's performance is expected to exceed the GTX 580 at the $350 to $400 price range. In addition, it is expected to outperform AMD's HD 7950 at similar price point and challenge the HD 7970 for the performance crown. The GK104 looks to be the similar to the current generation GTX 560 Ti with regards to price to performance in its category.

Please keep in mind, of course, that these specifications are from 3dcenter's supposed reliable source. We won't know for sure until Nvidia shows its hand. Stay tuned!
