iGenCPU results on UltraSPARC T1 (T2000) and UltraSPARC IV+ (V490+)
By mrbenchmark on Dec 14, 2005
This is an update on my previous entry, adding the UltraSPARC T1 CoolThread server T2000 and the V490+.The throughput increase between the UltraSPARC IV+ and the UltraSPARC IV is fairly proportional to the clock frequency.No surprise here. The simplicity of this microbenchmark does not allow taking benfits of many of the UltraSPARC IV+ innovations.
Regarding the T2000, please note that I am not afraid to publish the results. This is not a marketing blog...Indeed, this benchmark is not recommended for the UltraSPARC T1 due to the fact that 25% of the instructions are floating point operations (see two previous blog entries).
It does not prevent us to collect the data. Please remember that we want our customers to run the right platform for their workload. So, if your workload is generating more than 2% of floating point operations, the UltraSPARC T1 is probably not what you should choose....
Note : The column threads is the number of threads used to observe the highest throughput with a response time (RT) less than 100 ms.
|Processor||Frequency||# CPU||# Cores||Ram||OS||Threads||Fractals/s||RT (ms)|
|Intel XEON||3 Ghz||2||4 (HT)||4 GB||S10 03/05||3||31.16||96.26|
|Sun UltraSPARCIIIi||1.2Ghz||4||4||8 GB||S10 03/05||4||53.01||75.4|
|AMD OPTERON||2.4Ghz||4||4||8 GB||S10 HW2||5||90.18||55.4|
|Sun UltraSPARC IV||1.2Ghz||4||8||8 GB||S10 03/05||8||98.88||80.8|
|Sun UltraSPARC IV+
|Sun UltraSPARC T1
Let me know your thoughts....
Next, I will publish a description of the iGenRAM 1.6 and related benchmark results. We will see that the T1 is pretty good at this....
