: 我想请问一下, SIMD是在 pentium mmx里就有的技术，为啥 pentium
: mmx不叫 multi core阿
few comments:
1. Larrabee is not just for media or graphics. it has long term target.
Intel invest in it is to bring all Graphic/media/financial/AI etc,
computation back to X86 and ISA world, which is the strength of Intel.
2. AMD merge with ATI happens after the kick off of Larrabee.
3. Nvidia is expensive and has too much overlap with Intel. at the same time
Nvidia doesn't want to be bought out by Intel.
4. 80 core project is for research but a lot of technologies, such as inter-
core connection and communication, used in the project will be used in the
future Intel product. this is a really critical project for future multi-
core or many-core product.
5. multi-core is the trend. GPGPU or GPCPU will be at war in these two years
few more more comments
1. don't just use your home computers and the applications you are running
at home to think if multi-core is useful for you or not. if Intel/AMD just
focus on Home PC, they are dead long time ago. Server/Graphic/Embedded is
the market that has higher margin.
2. single core CUP has performance bottle neck when core frequency reach
above 4G. at the same time the power consumption is higher. big data center
and server farm need to pay the electric bills and build special AC. right
now, the CPU is just a <80w part. multi core CPU can have dynamic power
management scheme to shut down the power for an individual core to bring
down the total power consumption.
