From Outside it s identical to Core 2 duo, Pentium D 935 uses also Socket 775 and have 376 million transistors. It is also engraved in 65 Nm, but its thermal envelope is higher since is fixed at 95 Watts. Its frequency of operation is 3,2 GHz, that with a multiplying coefficient of 16x for a frequency of buses fixed at 800 MHz. The processor integrates 4 MB in its second level with 2 MB for each core. The voltage of Pentium D 935 is variable and oscillates in general between 1,2v and 1,3375v.
Pentium D 935 seen by CPU-Z
With those which even believed that Pentium D in process of disappearance, INTEL proves that such core still alive. Marketed with the price of 119 dollars part per quantity of thousand, this new representing of Pentium family is based on the Presler core. This processor Dual core does not propose any new functionality and we will find the well-known mistakes of Netburst architecture with FSB, 800 MHz only, The absence of direct communication between the core, The L2 cache is not shared between the cores and the latency times of cache is too high.
In short, Pentium D 935 will not revolutionize the world of processors, and This is not the objective of INTEL with this new reference. The founder proposes Pentium D 935 primarily as a solution of update to the current owners of platforms Pentium D which do not want to change their motherboard to pass to Core 2 duo. we note in that Pentium D 935 is identical to Pentium D 940 except that it loses the assumption of technology virtualisation ,INTEL VT.
The first thing which comes to mind when we considers Core 2 duo E4300 is due of course to its potential of overclocking.. Thus, on our motherboard , we could without changing the multiplying coefficient to pass from FSB800 to FSB1066. Consequently, our given processor with 1,8 GHz operated at 2,4 GHz 33% improvement and this without any effort!
Of course, we were not satisfied with this result :-). We thus could reach the 2,7 GHz successively then the 3 GHz by increasing the frequency of the bus system and by maintaining constant multiplying coefficient. 333 MHz FSB, the system start to loose stablity and we had to increase the voltage in order to preserve a perfect operation. Thereafter, we push the processor successively to the 350 MHz FSB then the 375 MHz. With 375 MHz system bus , Core 2 duo E4300 worked at 3,4 GHz this is an increase of more than 88% of its initial frequency. To reach the 3,4 easily GHz, we had to change our memory to DDR2 Corsair PC8500 . After several benchs in loop, our Core 2 duo E4300 was surprisingly stable at 3,4 GHz for a maximum temperature of 65°C in full load. Let us specify besides that we preserved our INTEL box cooler for the tests of overclocking . alas the 400 MHz remained instable in our test .
Core 2 duo E4300 flashé to 3 GHz then with 3,4 GHz!
On its side, Pentium D 935 is also good overclocker. we easily could make him exceed the 4 GHz while passing the FSB with 266 MHz and by maintaining constant multiplyer coefficient. With a coefficient of 16x and a FSB 266 MHz, our processor worked at 4,27 GHz. While forcing a little we arrives at the 4,4 GHz at the price of increase in the vcore of processor. Beyond, the situation becomes complicated and we did not succeed in preserving a stable system with FSB 300 MHz.
Pentium D 935 working at 4,4 GHz!
To check the impact of our various overclockings in performances, we systematically launched our custum demo with FarCry. The results are expressed in the graph below and as u can see it the simple fact of passing from FSB 800 MHz by default to 1066 MHz increases 28% in the performances of Core 2 duo E4300. By reaching the 3,4 GHz our Core 2 duo E4300 does better than Core 2 duo E6700. . As for Pentium D 935, our overclocking boost its performances to 27%: it is well but not sufficient to equalize Core 2 duo!
We benefit from this test to check the electric consumption of the last-born children from INTEL. With this intention, we lanched during several minutes the utility Prime 95 then we noted the electric consumption delivered by our wattmeter for the whole configuration. Power Consumption is indicated in the table below and as u can note , Core 2 duo E4300 proves to be particularly modest, and this even in full load! Not more than 174 Watts in full work, when the machine Pentium D 935 reached all the same 214 Watts in full load.

Doom 3 v1.3 - 1024x768x32
For Doom 3, Core 2 duo E6700 is without any doubt the fastest processor. Contrary Pentium D 935 shows serious signs of weakness, in spite of its 3,2 GHz, whereas our Core 2 duo E4300 finishes before the last. Athlon 64 X2 4200+ EE is faster here then E4300 by 1,3% whereas Core 2 duo E6300 is 3% faster.
Far Cry v1.4 - 1024x768x32
Pentium D 935 show poor performance here. On the other hand, Core 2 duo E4300 precedes here Athlon 64 X2 4200+ EE with higher performances about 9%. comparing Core 2 duo E4300 with its brothers, we realizes that Core 2 duo E6300 is 5% here more powerful whereas the models E6400 and E6700 are largely at the head.
Call Of Duty 2 - v1.3 - 1024x768x32
Core 2 duo confirm here their advantage over Athlon 64 X2 whereas even Pentium D 935 succeeds in doing better than Athlon 64 X2 4600+ EE. On the other hand the difference between Core 2 duo E6300 and its little brother E4300 is far from being obvious whereas Core 2 duo E6700 is logically first.
Admittedly Core 2 duo E4300 is not the most powerful processor of this test but it is not either a the weakest one . In our eyes, This is the processor of the moment! Not only it makes possible to INTEL to financially extend its range of processors Core 2 duo moreover, it is about a splendid gift for the amateurs of overclocking. Without effort, the FSB of Core 2 duo E4300 can passe from 800 MHz to 1066 MHz with this increases in frequency will benefit largely the performances. But the small last of INTEL does not stop there and it could reach easily the 3,4 GHz in overclocking against an initial frequency of 1,8 GHz, that is to say practically the double! . Remain a small problem for INTEL, Core 2 duo E6300 is currently proposed at the same price as new Core 2 duo E4300, whereas the model E6400, expensive seems to lose its interest.
On its side, Pentium D 935 show modest overall . it is not a bad processor. It offers performances equal to Core 2 duo E4300 using default frequency, is negotiated with a completely advantageous price and it can easily be overclocked! we could make easily pass from clock speed of 3,2 GHz to 4,4 GHz! even if Pentium D 935 preserves the defects of family Pentium D, with a high consumption and important heating, it remains particularly interesting to update at few expenses an existing platform Pentium D. On the other hand, we will not advise Pentium D 935 for new equipment because of reduced evolutionarity which offers the attraction of Core 2 duo whose price is hardly 50 euros more expensive.
