MrBenchmark benchmarks : Opteron vs UltraSPARC IV vs UltraSPARC T1
By mrbenchmark on Dec 09, 2005
Whiners came to me saying : "MrBenchmark : Enough theory, please give us some benchmark results.."
And I said, fine...so here we are ..I will publish some informal benchmark results in this forum. And Yes I will compare
UltraSPARC IV, IV+, Opteron , UltraSPARC T1 and even Xeon !
Let me present the first microbenchmark of my serie . It is called iGenCPU. It is written in 100% pure Java. I am using Java 1.5
The iGenCPU benchmark is a JavaTM-based CPU micro-benchmark used to compare the CPU performance of different systems.
Based on a customized Java complex number library, the code is computing Benoit Mandelbrot's highly dense fractal structure using
integer and floating-point calculations. The simplicity of the code as well as its non-recursivity allow a very scalable behavior using
less than 64 Mb of memory per thread.
iGenCPU reports multiple statistics. We are mostly interested in analyzing iGenCPU_Thp (how many fractals per second can we
compute with this number of threads ?) and iGenCPU_RT (what is the average time needed to compute a complete fractal with this number of threads ?)
IgenCPU use the system this way as represented by my iTarget chart :
Next to come : our first iGenCPU benchmark result (table & diagram ): V40z (4xAMD Opteron @2.4Ghz with 8GB RAM ) vs V490 (4xUltraSPARC IV 1.2Ghz 8GB RAM)
