[業界消息] Intel Core i7-5770K to Receive High-Performance IGP with 128MB eDRAM

Intel Core i7-5770K to Receive High-Performance IGP with 128MB eDRAM

果然Intel唔會戒得到eDRAM

仲有, 14nm點解會推到Q4?

而家懷疑緊係堆Haswell貨未走哂多
EUV本身都難整, 邊有咁易換到EUV

查實佢咁做, CPU 會唔會死快 d?
應該唔會死快d, 不過成本高

跟佢一齊塞
其實用side-port類技術已經得

Haswell CPU+GPU: 264mm^2 (est)
Haswell eDRAM: 84mm^2

Est. Broadwell: (14nm)
CPU+GPU: ~100m^2 (without any CPU and GPU improvements, pure and prefect die shrink), ~200mm^2 (with L3 and GPU improvement, not perfect die shrink due to EUV)
eDRAM: ~30-40mm^2

叫 GirlFriend 或者 TSMC 加速 TSV maturity 咪得
其實根本唔駛
以而家的socket size, 唔駛die stacking, 只要MCM就得 (Intel都係用MCM)

MCM 貴,yield 唔方好,雖然話 AMD 黎緊有粒 embedded GPU 係單封裝 + 128-bit 7Gbps GDDR5
HBM SK Hynix 聲稱 14 年尾量產

MCM先唔貴

你諗下Intel mainstream Netburst CPU都用MCM就知唔貴
Yield更加會高, 因為係test好chip先封裝

用得K既都唔會用佢既IGP啦
而且又唔似AMD咁有得玩crossfire
Mobile會用到, 尤其係Apple

不過家用真係無乜人理K系用咩IGP

唔知啦。我問開嘅路人甲係咁講。
不過用呢種 solution 無得搞 lidded package,除非個 socket 再做大佢。
MCM成本平d, 不過用唔到lidded package又係搞笑, Pentium-D咩來

同埋再往上走 package size 都限住你啦,最後又係 wide i/o 嘅市場。
一粒搞掂,起點 128 GB/s
我諗Intel / AMD都係講左成本先講效能,
講真, 而家IGP唔打機, 唔做GPGPU野根本夠用, 所以而家推上去一定睇成本

亦都無講過只可以用DDR-3做side-port
1粒GDDR-5已經22GB/s

大佬講緊一粒 Trinity size + 4 粒 豬DDR5
唔會啦, 1粒起2粒止, 成本太高同埋粒APU賣唔到咁貴, 加4粒的flag-ship APU就要賣US$200以上

依家 Richland top-bin 賣到 $122...

無嘅,最終又係睇實際應用。實際上 (目前) IGP 用途得打機好睇,所以最後價錢又係睇 CPU。Desktop 對 SFF 要求又唔太高。只不過作為 fan屎得閒發夢咁解 (IF TSV 成本  ...
2 dram chip is enough

22GB/s v.s. 128GB/s
你要諗下AMD APU對bandwidth幾敏感先得

if the bandwidth difference is small (e.g. 64b @ 6Gbps vs DDR3), you need sophisticated changes to the video memmgr to utilize all bandwidth available in the system (e.g. texture streaming @ GDDR, fr ...
AMD has done it with side-port.
Intel is doing the same for Iris Pro.

That's just a very low-end graphics, and I am talking about maximizing the performance instead of capability. Iris Pro one is cache-based according to the current information, and it is different fro ...
I will wait and see...

I expect AMD to go for side-port again with 1-2 chips.
