I had tested many hardwares during all this years from K6 till phenom and MMx 233 till Q6600.From S3 savage8 till 3870 X2.Let me talk about my experience:
Old days:
1. K8 was faster than any P4 per it's price all the time.(maybe clock is not a good factor because it was a big clock gap between K8 and P4)
2.Ati 9xxx were faster than Fx5xxx(and most of 6xxx) from nVidia (not per price sometimes)
3.Am2 was a big failure from AMD because: DDR performance was twice faster than DDR2 .(specialy in dual mode)
and If AMD did not switched to am2, today we had DDR1000(should Perforemed like DDR3 2000!)
Dual channel performance has a big gap between DDR2/3 and DDR.
this is where users switched from good performed 939 to Intel Core2 .
But not because they do not have any feature on their M/boards ,because
they could not find 939 X2 CPUs easily ,then DDR ram went to fazed out.
So AM2 is slower than 939!(per clock)... you can see an 2.6 ghz opteron dual core is faster than x2 5200 (windsor) with same cores ,with same chipset ,but the slower is AM2.Why? because DDR2 800 <= DDR 400!!!
today :
4.HD 3870 seems to perform slower than 8800gt BUT:
a.Picture quality (3d maps) are in better quality if you take picture from games?!
It means 3870 can perform even faster than 8800gt while the quality [SEEMs] them same
(but not the same in game option!)
b.If you change the EXE file of your game for example from Crysis.exe to Crysis2.exe the game perform slower
than before in nVidia.(depends of the driver) means nVidia cheats!
While all options are high but picture quality is lower than ATI 3870.
c. 3870 is a RV chip it means it is a VALUE product.
3850 performs 80% faster than 8600GTS!
while 3850 is targetting 8600gts,3870 X2 targetting 8800 ultra,and it is a better product while quality of game details differences.(ATI is better at same detail)
d.SLI from nvidia only can do 50% faster even with 3 card the third card is wasted!! But crossfire is making 80% boost for two and more han 200% in quad CrossFire.So this is where ATI helps AMD,but not phenom!
e.Still there are many many bug reports from nvidia 88xx and 9600 cards.this can be reduced by changing drivers but there is no garranty for it.This means I go ATI these days!
5.All the time M/Bs detected AMDs new CPUs at least in the name of "Unknown AMD " But today phenom does not boot with 98% of AM2 boards.... this is a new big mistake from AMD pushing AM2 users to Intel core2.
6.Memoy controller in 9500 and other low-clocked phenoms is very poor,perform like a 754 DDR1 CPU,in clocks higher than 2.8 this problem solved,This means performance of phenom goes higher per clock! then a 3.2 GHZ phenom (shanghai) may beat a core2 per clock!who knows!
7.In intel Max of REAL performance of any Ram is this: 400MHZ for fsb800,533mhz for fsb 1066,667 mhz for fsb1333,800 mhz for fsb 1600, and this is a chipset limitation!and will change in next generation.
8.X2 6400+ is a CPU you can buy it at 180$ (boxed with heat-pipe fan)... It is a power hungry choice but it's price make it a good choice.Which is faster than 6750 with the same price.this CPU has a good performance in Memory.(around 10000MB p/s) ,But it's technology is old.Why Amd cannot build a low power cpu at this performance?This could be another mistake!
9.Clock is not a problem.I think power waste is the problem.Phenom is not a good per watt CPU ,if it was.... there is no problem with it's lower clock/performance ratio and While I am waiting for a better low-power and higher clocked phenom.
So AMD or Intel? Nvidia or ATI? thats the question...
