The auto translation did not work for me.
Intel showed off Clovertown quad-core server CPUs running on the Bensley platform with FB-DIMM memory at Spring IDF Taipei. Clovertown is basically two 65nm Conroe CPUs stacked together, with total of 8MB L2 cache. This page contained the benchmark scores for a 2P Clovertown. The reported clockspeed was 2GHZ (could be 2.13GHZ, same as Conroe E6400).
For single threaded test, the 2GHZ Clovertown got a Cinebench 9.5* score of 362. Daniel J. Casaletto, Intel Vice President, Digital Enterprise Group Director, Microprocessor Architecture and Planning, was running the demo. For 2P 8 cores, the score scaled to 1723, or 4.7x. Adding 7 cores led to 3.7x more performance. I think this is quite poor, you get only about half a core's worth when you add a core.
FSB is an Intel bottleneck. Eight Conroe cores fighting for a 1066MHZ FSB is not a pretty sight: in 2P Clovertown each Conroe core gets only 133MHZ bandwidth or 1GB/s, not much better than a 80486 (Well, you may say there is the dual bus, so it should be 266MHZ, but 8 cores of cache coherence traffic must be considered). Fortunately, Cinebench doesn't put a lot of load on the bus, it spends most of the time digesting the data.
Let's pay more attention to this photo here, which shows the 2P Clovertown in action and is quite exciting. Look at the upper left corner, it reads Cinebench 64 Bit Edition. Finally, we can see Intel got 64 bit working, it's running the 64 bit version of Cinebench! My congratulations to the Israeli engineers for getting AMD64 figured out. Welcome to the exciting world of pervasive 64bit computing! Now, Microsoft will allow the world+dog to go 64 bit.
