atom升performance暫時見到佢唔知走左去邊..power亦唔見得做到好突出..
但core要降power..做到之餘仍keep到一定performance..
最尾atom可能會輸蝕.. 而intel既強項..performance仍然係佢賣點..應該唔會give up的.. ...

Atom加既係power efficiency

Core的power已經無乜好降, 除非放棄好多performance-orientated既野

睇佢haswell之後果個架構先有結果..睇wiki原來係skylake(睇好佢呢舊野..講左成6-7年都有)
成日覺得intel整緊粒超級秘密野.. 會完全同core唔同..但幾時出同出唔出到係一個問題..

Intel同人講Phil優於NV/AMD原因係x86..就係咁簡單..existing既轉移可以比起其他花更少時間..
唔好唔記得intel本身係有粒larrabee在先..

You still need to rework your code on Phi in fact (128-bit to 512-bit vector, and Phi has no support of SSE) and it still takes you time to optimize as on GPUs. The real advantages of Phi are its higher serial performance per core, and its large coherent cache. These enable Phi to cover algorithms that GPU may not familiar with. On the other hand, these become power and performance disadvantages relative to GPUs in traditional throughput workloads, for instance, rasterization-based rendering pipeline.

By the way, there are developers complaining about Phi's current development tools, which make heavy use of pragmas.

計錯數

實際大部分program (尤其係server) IPC的確係細過2, 但係以此做Bulldozer藍圖 (2x2 IPC per module) 就幾大問題下

講伺服器既話，睇落未必係核心既問題。系統架構...
用呢個做例子，within the node 一切正常，飛得甩上代，咁核心算唔算達標？beyond the node 呢，開始黎料。

AMD其實最大問題一個字.."錢"
佢有intel咁既財力依家應該唔會搞成咁..

唔係錢, 最大問題係 AMD 個 Board !

話時話dirk去左邊..

我都想知
好似去左 間 Startup

另外按照 AMD 既 blog post 所講，AMD 係 CAD/business. 市場持續努力中，更多既 ISV 認證，更豐富既產品同更好既 OGL support 之類。

AMD in GDC sum up:

引用:

Rage3D
[...] they have not yet begun their assault on the HPC and GPU Compute markets in earnest. This seems contrary to previous messaging, but is backed up by AMD's internal shuffling to create a new and high-power cloud and HPC compute sales and PR team.

AMD aren't done with the Radeon HD 7000 series, and still have new products to come in 2013. They are currently operating on a cadence of three new chips a year, which is very fast.

So, are the days of high performance high end graphics over? Not according to John. In fact, he offers the belief AMD are going after the high end like they never had before -- everything starts with designing for the PC gamer first. Effective HPC products from AMD can differ from their consumer counterparts by about 3% in terms of design, [...]
