Rumor:: GTX680 will have Turbo boost, faster then 7970 in BF3, but lower 3D Mark

Here are some key bits of information concerning the upcoming GeForce GTX 680, a performance single-GPU graphics card based on the 28 nm GK104 GPU by NVIDIA. The information, at face value, is credible, because we're hearing that a large contingent of the media that finds interest in the GPU industry, is attending the Game Developers Conference, where it could interact with NVIDIA, on the sidelines. The source, however, is citing people it spoke to at CeBIT.

First, and most interesting: with some models of the GeForce 600, NVIDIA will introduce a load-based clock speed-boost feature (think: Intel Turbo Boost), which steps up clock speeds of the graphics card when subjected to heavy loads. If there's a particularly stressing 3D scene for the GPU to render, it overclocks itself, and sees the scene through. This ensures higher minimum and average frame-rates.
Second, you probably already know this, but GK104 does indeed feature 1,536 CUDA cores, which lend it a strong number-crunching muscle that helps with shading, post-processing, and GPGPU.

Third, the many-fold increase in CUDA cores doesn't necessarily amount to a linear increase in performance, when compared to the previous generation. The GeForce GTX 680 is about 10% faster than Radeon HD 7970, in Battlefield 3. In the same comparison, the GTX 680 is slower than HD 7970 at 3DMark 11.

Fourth, the NVIDIA GeForce GTX 680 will very much launch in this month. It won't exactly be a **-launch, small quantities will be available for purchase, and only through select AIC partners. Quantities will pick up in later months.

Fifth, there's talk of GK107, a mid-range GPU based on the Kepler architecture, being launched in April.

Next up, NVIDIA is preparing a dual-GPU graphics card based on the GK104, it is slated for May, NVIDIA will use Graphics Technology Conference (GTC), as its launch-pad.

Lastly, GK110, the crown-jewel of the Kepler GPU family, will feature as many as 2,304 CUDA cores. There's absolutely no word on its whereabouts. The fact that NVIDIA is working on a dual-GK104 graphics card indicates that we won't see this chip very soon.

Key point:
(Info sharing only, tech's credibility is normally from ok-good, what it said seems reasonable. However, if you don't like it or a die hard fan boy of ATI, feel free to consider it as NV adv)

1. K104 將引入turbo-boost特性, 頻率會與顯卡負載同步。GPU會自動超頻，以保証提高最低和平均幀數。

2.GTX 680在BF3中大約比HD 7970快10%，但在3D Mark 11中比HD 7970慢。

3. NVIDIA的GTX 680肯定會在本月推出，但首批數量會很少，一些渠道才能獲得，數量會在幾個月裡逐漸增加。

4. GK107，同樣基於Kepler架構的中端卡，將在四月正在推出。

5. NV下一個Dual-GPU card 將基於GK104, 會在5月的GTC上發布。

6. GK110，擁有2304個CUDA，從NV著手Dual-GK104發布表明，一段時間內不會見到GK110

turbo-boost~ 有新意喎~...
期待期待~

MIMD不是已同HT差不多了嗎

學野
