INTEL 65nm dual die Pentium D-950 Presler re-fragged

Another set of benchmarks, the INTEL Presler fighting against AMD's second team, the old Athlon 64 X2 4800+, the INTEL Pentium D 950 3.4GHZ with 4MB of cache got hammered on the head again and again -- no surprise here. What is interesting about this test is the Apache Bench which measures Apache HTTPD server performance in serving web pages. In a simulation of 50,000 users, the old dog Athlon 64 X2 4800+ handled 1453 page requests per second, the spanking new 65nm INTEL Pentium D 950 3.4GHZ Presler dual die with 4MB cache handled 986 requests per second, roughly half the speed of the AMD X2.

An Athlon 64 X2 3800+ did 1070 requests per second in Apache bench, 10% faster than the 65nm Pentium D 950. Try check the prices.

So if you are a web master, don't be fooled by the massive 4MB cache and 3.4GHZ clockspeed of INTEL, its obsolete architecture is a limiting factor. DELL is selling PowerEdge 850 rackservers equipped with INTEL Pentium D for $4000. It's your money.
