Benchmark
Scores
SimHQ's
Allied Force testing consists of two missions, which are now
officially a part of our benchmarking suite. These two tests
are titled Test 1: Ground
and Test 2: Air.
Based
on the Korea map, Ground is a short MUD moving flight that
leaves Mandumi, heads over the FLOT, and attacks an enemy
supply depot that has way too much AAA and SAM cover. This
test is run for six minutes.
The second
test, Air, is also based on the Korea map. It is a mission
that starts with the threat warning siren blaring as your
flight comes under immediate attack by Su-27s, with lots of
jinking at angels 20. Air is a shorter mission, running for
three minutes.

Test 1:
Ground
Not unexpectedly, AMD's X2 4800+ dual core leads the pack
for all recorded frame rates. The 4800+'s lead is 30% higher
than the other tested dual core, Intel's 840, and more than
20% over Intel's P4 3.73 single-core CPU, which itself managed
to outperform the FX-55; one has to wonder if Intel's hyper-threading
is paying dividends with Lead Pursuit's thread optimizations.
Intel's 840 lags behind all the high-end processors and barely
manages to outperform the single-core 3800+, a performance
that's fairly consistent with past Falcon testing. The 2700+
trails significantly behind, though this isn't unexpected
since its test system is considerably outdated compared to
the other systems.
The following
are frame rate graphs showing the frames per second results
from each processor's testing of the Ground mission as recorded
by Fraps.
Test 2:
Air
The Air
mission allowed the 4800+ to truly shine, outperforming both
the FX-55 and P4 3.73 by 20%. The FX-55 likewise outscored
Intel's P4 3.73, though only by the slightest of margins.
The dual core 840, however, lagged behind all the other high-end
processors and was even outperformed by the single-core 3800+
by 10%. Not to unduly belabor the point, but this score is
quite consistent with Intel's dual core performance, which
simply appears to be unable to overcome the clock speed differences
despite the presence of an additional processor core, and
simply gets blown out of the water (or, perhaps, we should
write sky) by the AMD X2s. Case in point with the Air test:
the 4800+ outperformed the 840 by a solid 50%. The 2700+ again
came in last, trailing behind the other processors by a considerable
margin.
The following are frame rate
graphs showing the frames per second results from each processor's
testing of the Ground mission as recorded by Fraps.
