4MB L2 cache. When I run benchmarks on it the results are highly
variant depending on the software I use.
Some will give the CPU as 800mhz !!! some even less than that......
I wonder if this is a genuine T7300 at all ...lol.
Ok...I got 1 benchmarking software called FreshDiagnose that is
supposed to tell me all that happening with my lap.
Running a CPU Benchmark brought the Speed the Lowest - just 700mhz
compared to 10 other CPU's it had including 3 Hz Hyper threaded P4. So
I was the the LOWEST end of the scale as far as MHZ is concerned.
BUT the my CPU SCORED the HIGHEST- Dhrystone ALU ( MDIPS ) & Whetstone
ALU ( MWIPS ) with the same competitors
I know a bit from definitions what these mean but why is the INVERSE
relationship between MHZ and MDIPS/MWIPS.
Re: 1 for Hardware Buffs ...What is the difference between Dhrystone ALU ( MDIPS ),Whetstone ALU ( MWIPS ) & MHZ?
Many of the Intel processors have EIST (Enhanced Intel Speedstep Technology).
When the computer is idle, the clock rate of the processor can be reduced,
which saves power. Even desktops can do this now.
When you start a computation with a measurable computing load, the response
of the software is to increase the CPU clock speed (to its "rated" value).
In your case, that would be 2GHz.
But if the computer is relatively idle, it will be using a reduced clock
An application such as RMClock may be able to display the variation.
At least, that might be the application I'd try first. I cannot
really test that on my computer, because EIST is broken on my
motherboard :-( My processor runs full speed, all the time.
If you go to Control Panels, and use the Power Options (or something
with a similar name), there are power profiles in there. One of the
profiles will be a high power one - the result should be that the
processor stays at 2GHz even when the OS is idle. It might be
something like "Always On" for example. You could change the power
profile, then rerun the benchmarks. (Record where it is now,
so you can put it back later. The lower power profile helps
extend your battery life.)
Other than RMClock, I don't know if there are any good utilities
that can tell you exactly what is going on. CPUZ is a popular one,
for identifying the clock speeds and key settings of the hardware,
but I don't know if it does a good job of following the dynamic
behavior. (There is a danger with any utility, that if it loads
the CPU itself, it can trigger an increase in frequency.)
