confusing Intel names in benchmarks

[mccririck]

Intel Core2 E8500 scores 2068

Intel Core2 Duo E8500 scores 2317


This is just one example, and I dont understand, are these different processors??

[mccririck]

I'm talking about the CPU benchmarks section btw.

[David (PassMark)]

The names are read directly from inside the CPU themselves. So it is likely that Intel released 2 slightly different versions of the CPU and didn't keep the naming consistent.

We check the situation and merge them if required.

[mccririck]

The funny thing is the ones that just say Core2 are all slower than the ones that say Core2 Duo.

*edit* actually this isnt correct sometimes the Core2 ones are higher, eg the E6400

[mccririck]

Some of the scores surprize me:

Pentium E6300 - 1659
Core2 E6320 - 1136


wtf!??

[mccririck]

Look at this one:

E7500: 1407

E7200: 1683

The E7500 is supposed to be a better chip.

[mccririck]

dodgy CPU benchmark result

E7200 = 1683
E7500 = 1407

The E7500 is basically a faster version of the same chip so how does the E7200 outperform it?

[mccririck]

Also the E5200 seems to out-perform the E5300. How reliable are all these results!

(I've merged the two threads on this topic)

It has been determined that the "Core2" CPUs lacking the "Duo" in their name are incorrectly labelled and have been merged into their proper names. Any out of order placement of these mislabelled CPUs simply came from the fact that there were a far smaller number of them and they were being thrown off by outlying results.

There may be a few order discrepancies remaining however I think for the most part they are small enough to be within acceptable margins of error. Remember that this data is completely user submitted and many peoples systems may not be running optimally. The higher number of samples (as can be seen be mousing over the result in the charts) the more reliable the data for that particular CPU is.

At first we thought the difference between these CPUs might have come from the e0/c0 stepping difference in these CPU types however more closely inspecting the baselines has shown this not to be the case and both names had a mix of different CPU steppings.


"Pentium E6300 - 1659
Core2 E6320 - 1136"

There is in fact an E series of Pentium CPUs that are completely separate from the Core 2 line and whose model numbers are as such unrelated.

[mccririck]

There's still some duplicates:

Pentium Dual Core E6300 - 1871
Intel Pentium E6300 - 1659

Also the Core2 Duo E8335 seems to have 2 different speeds, 2.66GHz and 2.93GHz

[Michael (Passmark)]

The dual core Pentiums have been merged.

As for the CPU types with duplicate speeds we are aware of this however are planning on leaving them as is for now. After a bit of investigation it seems that one of the speeds is in fact from the mobile version of the processor whilst the other is for the desktop version.

The CPU names are retrieved directly from the CPUs themselves, but desipte this they are not always reliable. This is what causes these naming discrepancies when the charts are generated. We do try and clean up bad data however with a constant influx of new CPUs onto the market there are always going to be some anomalies.
