[citation][nom]Diabowx[/nom]Found some interesting things/facts in this review , These are follows : 1.Core 2 duo and core 2 quad doesn't have L3 cache where as core i series , celeron and pentium does have L3 cache . 2.Core 2 duo and core 2 quad uses DDR2-1066 , 1000 , 1045, 890 Rams , where as core i series , celeron and pentium uses DDR3 1600 and 1333 respectively .3.Core 2 duo and core 2 quad uses DDR2 4 GB Ram clocked at 1066 , 1000 , 1045, 890 where as core i series , celeron and pentium uses 8GB DDR3 Ram clocked at 1333 and 1600 . Simply i believe (may be i m wrong ) that core 2 duo and core 2 quad will be no matched with these core i and pentium series because of the Rams they were using , As we have already seen in other posts about how Ram timings and frequencies affects gaming and all that apps used in this benchmark .May be we get equivalent performance when we use exactly same hardware (DDR3 Rams) for these cpus . Remember DDR3s are faster than DDR2 Rams . I have one doubt regarding the power consumption , power consumption in case of core 2 duo and core 2 quad in cpu load 122.4w and 154.5w and in gaming 264w and 299w respectively , Then how does they consume more power than there thermal limit ?They should have invented a method to find out how much power cpu(only) using , Not the power consumed at AC source , even converting Ac to Dc wastes some power .Lastly what i m thinking is (again i may have been wrong) today's game are not optimised for core 2 duo and core 2 quad processors .[/citation]
Cache and ram does influence performance, but simply slapping DDR3 with a Core2 won't make up for the difference. Mostly because they are incompatible and you can't do that, but there are several architectural changes that account for the difference in performance as well, such as the memory controller being on die for Ivy Bridge.
Measuring the power consumption at the socket is the easiest way to distinguish CPU power consumption differences. There are other ways to measure CPU power specifically, but in this case the large majority of that difference can be attributed to changing out the CPU.
Also TDP != power consumption. TDP is reported differently between different manufacturers, but more or less it is a guide to how much cooling a part needs.
And finally, they don't optimize games for specific generations of chips. Changes in CPU architecture from Core2 -> Ivy Bridge may utilize software more efficiently (pipeline, branch prediction, etc.), but it's not like programmers are writing specifically for Ivy Bridge or any other CPU.
