AMD Athlon 64 FX-60: A Dual-Core farewell to Socket-939

Gaming Performance using Battlefield 2, Call of Duty 2 and Quake 4
Gaming performance is pretty respectable for the Pentium EE 955, with the chip being quite competitive with AMD's Athlon 64 X2 4800+.
The most interesting thing we found is that even with a high end GPU like the Radeon X1800 XT, a number of games are still quite GPU limited even at 1024x768, which is why you don't see F.E.A.R. and Splinter Cell: CT here. Even some of the games that we did required us to turn down some of the detail settings to start to stress the CPUs.
The pendulum often swings between games being CPU and GPU limited, and it seems that with the latest generation of games, we are definitely more GPU limited.
We should also mention that we had to re-run our AMD numbers in this test since the last review as we were seeing sub-par AMD performance. A clean install and re-run of the numbers yielded the results that you see today; the Intel numbers didn't change.
We did run with SMP support disabled, as we found in our last article that the game gave us higher frame rates without it enabled.

Yes, It is well known that P4 need more power than X2, but P4 is still able to overclock.While X2 need less power than P4, but both of them(anand & xbitlabs) find that they can't OC X2 any more (15X).
Betwon - Tuesday, January 10, 2006 - link
In fact, those tests show that:X2 is overclocked in those benchmarks still slower then P4.
We find the truth.
Without OC:
955 is 3.46GHz, FX-60 is 2.6GHz --> the ratio is 1.33 (3.46/2.6). -->In most tests, X2 is better than P4.
OC:
955 is 4.26GHz, FX-60 is 2.9GHz -->Now, the ratio is 1.46 (4.26/2.9). -->P4 starts to be better than X2.
It is very simple:
The ratio
flyck - Tuesday, January 10, 2006 - link
p4 wins one test the others it is way behind. you reversed it. p4 overclocked is still slower in those benchmarks.
overclocked
FX 2.8/ FX 2.6/ XE 4.266
UT 2004 : 95.8 / 90.5 / 82.4
Cinebench : 963 / 891 / 928
only tests they did overclocked. p4 wins none of them. it is just edges above or around the normal FX 60.
ow yeah your ratio... you have found a way for perfect scaling ? great, there will be people intrested....
not even talking about the fact that your primary ratio is wrong because @ those frequencys p4 wins nonthing, so is not even equal. and oced is comes close it will probably win some and lose some (like in those 2 test) so then they are about equal.
so the more accurate ratio will be 1.40-1.50. for equal performance. in which case p 4 should run above 4.5GHz before it has a noticeable gap over the FX60 overall.....

P4 better than X2.Ratio is the key.
The ratio below 1.33 -- P4 is behide.
ratio above 1.4x -- P4 is competitive. Intel 4.26GHz VS AMD 2.9GHz
For the ratio of intel 820 VS AMD 3800+ 165 170? see the benchmark of spec cpu2000 rates for 2 core 1 chip:
The float point performance(under windows OS/32-bit):
PD 820 SPECfp_rate_base2000 29.9 SPECfp_rate2000 30.0
http://www.spec.org/osg/cpu2000/results/res2005q4/...">http://www.spec.org/osg/cpu2000/results/res2005q4/...
170(939-pin 2GHz 1MX2) SPECfp_rate_base2000 25.2 SPECfp_rate2000 26.3
http://www.spec.org/osg/cpu2000/results/res2005q4/...">http://www.spec.org/osg/cpu2000/results/res2005q4/...
We don't find the benchmark of 165 and 3800+, but we find the benchmark of 175.
170(939-pin 2.2GHz 1MX2) SPECfp_rate_base2000 26.2 SPECfp_rate2000 27.3
http://www.spec.org/osg/cpu2000/results/res2005q3/...">http://www.spec.org/osg/cpu2000/results/res2005q3/...
We don't find the benchmark of both PD and X2/opteron dc under windows OS/64bit, so we can not compare the dual-core float point performance 64-bit directly.
The test--SPECfp_rate is the most important test for CPU float performance. AMD approbate SPECfp_rate for testing dual-core's FP performance.AMD think it is a fair test.

We find the 270(2GHz) FP benchmark of 32-bit under windows OS.http://www.spec.org/osg/cpu2000/results/res2005q2/...">http://www.spec.org/osg/cpu2000/results/res2005q2/...
270(not 939-pin ) SPECfp_rate_base2000 27.1 SPECfp_rate2000 28.3
But PD820 SPECfp_rate_base2000 29.x SPECfp_rate2000 30.x
better
Now, ratio is 2.8/2=1.4.

You know, I pretty much favor Intel chips, but I still wish you stop your ranting.Betwon - Tuesday, January 10, 2006 - link
You know, I do not favor Intel chips, and I wish you stop your favor of Intel.Because we know the spec is not favor of Intel, and AMD knew it.

rates275
It is FP benchmark under 64-bit and Linux, but not the FP benchmark under 32-bit and windows.
And 275 is 2.2GHz
PD820 is 2.8GHz
ratio: 2.8/2.2 = 1.22(only).
