The popular benchmarking suite PCMark'05 shows not only the
expected superiority of Intel Core 2 Duo E4400 over Intel Core 2 Duo
E6300 at computational tasks due to its higher clock speed but also
some minor lag in other tasks.
CrystalMark confirms the formerly produced results –
therefore, at tasks which require faster computations a CPU of higher
operating clock speed will be a bit faster, whereas at tasks of
processing large amounts of data a processor having the faster bus may
prove more powerful. We are verifying the theoretical inference through
practice...
For instance, data archiving packages are sensitive enough to
the RAM exchange speed, and Intel Core 2 Duo E6300 finds itself to some
more advantage at that.
But already at media data encoding it is the clock speed that
proves to be more important, so Intel Core 2 Duo E4400 leaves Core 2
Duo E4300 and Core 2 Duo E6300 having approximately equal operating
clock speeds behind.
3DMark’06 forecasts some advantage of Intel Core 2
Duo E4400 at modern games as well, but Intel Core 2 Duo E4300 will nor
lag behind.
It turns out that once the overall performance is not
restricted by the video card's performance, then Intel Core 2 Duo E4400
proves to be more efficient than Intel Core 2 Duo E6300.
Final words
Intel Core 2 Duo E4300 is therefore the slowest Core 2 Duo
processor to date, lagging behind the more expensive model and even
Core 2 Duo E6300 by 5-10%. At the contest between Intel Core 2 Duo
E4400 and Intel Core 2 Duo E6300, the winner is the former because at
most tasks it has proved a bit more powerful with the price set lower.
At the same time, Intel Virtualization Technology supported by Core 2
Duo E6300 remains unclaimed in most ways. Therefore, the choice is
evident especially if you are into getting higher performance without
paying extra.
We presume it's just these results which compelled Intel make
a transposition in the Core 2 Duo E6xx0 product line through a release
of Core 2 Duo E6320 and Core 2 Duo E6420 which offer twice as much of
the L2 cache size with the clock speeds being the same. We hope that
the hopefully early tests will tell if the move has proved reasonable...
We appreciate LLC
"PF Servis (Dnepropetrovsk, Ukraine) for the hardware
presented for tests.
