FLOPS

Fujitsu [富士铜:-)] board with SPARC64 VIIIfx processors. 

 

SPARC64 VIIIfx, which was developed as a processor for the K computer, uses Fujitsu Semiconductor Ltd.’s 45-nm CMOS process for semiconductors and is composed of eight cores, a 6MB shared level 2 cache, and memory controllers. Peak performance of 128GFLOPS at an operating frequency of 2 GHz is achieved with power consumption as low as 58W. 很可能是水冷——右中部朝上那个接头。128G / 8 / 2G = 8 FLOPS / cycle.

 

 

Intel E8400:

• Code Name: Products formerly Wolfdale
• Lithography: 45 nm
• Total Cores: 2
• Processor Base Frequency: 3.00 GHz
• Cache: 6 MB L2 Cache
• Bus Speed: 1333 MHz
• TDP: 65 W Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload.
• TCASE: 72.4°C Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).
• Package Size: 37.5mm x 37.5mm
• Processing Die Size: 107 mm2
• # of Processing Die Transistors: 410 million 平均每个晶体管占2.61x10-7mm2，即261000平方纳米，45*45/261000=0.00775862.

阿童木(Atom)挺强的嘛，32位浮点数4发射？
