E8600 VS Q9400 WHICH IS BETTER DUAL OR QUAD CORE By :Cpu review Posted:2008-11-21 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source Today we will compare the Intel core 2 Duo e8600 (Wolfdale) and Intel core 2 Quad q9400 (Yorkfield). Before us a high end dual core CPU and and a 45 nm quad core processors in the same price range . E8600 vs Q9400 Technical characteristics : Processor Intel core 2 Duo e8600 Intel core 2 Quad q9400 Technical process 45 nm 45 nm Code name Wolfdale Yorkfield Default frequency 3.33 GHz 2.66 GHz Bus Frequency 1333 MHz 1333 MHz Number of cores 2 4 Multiplier 10 8 L2 Cache 6 MB. 6 MB. (2x3Mb) VID 0.85V-1.3625V 0.85V-1.3625V] TDP 65 W 95 W In this case we have E0 stepping for the E8600 processor and R0 in the case of the Q9400. Here is the setup used for tests : Cooler : Thermaltake big typhoon VX @ 1800Rpm Motherboard : Asus P5K- E wi-fi ap (LGA 775, Intel P35, ddr2) Memory: OCZ DDRII PC-8000 platinum edition 2 x 2Gb Video card : PowerColor radeon HD4870 1Gb @ 800 \ 4000Mhz (Catalyst 8.11) + accelero S1 rev.2 \ turboModule Hard disks: Sata hitachi GLA 500Gb Power unit: Thermaltake toughpower w0117 750 Watts Operating system : Microsoft Windows vista ultimate 64-bit SP1 Overclocking the E8600 and Q9400 : Here is the setting used for Core 2 Duo E8600 CPU : 1.45 v (1.425 real) CPU PLL : 1.6 v FSB termination : 1.2 v North bridge : 1.55 v This processor was able to stably pass Linpack and OCCT at 4.6 GHz frequency with 1.45 v (1.475 Bios). Here is the setting used for the Q9400 CPU : 1.45 v (1.425 real) CPU PLL ; 1.6 v FSB termination :1.3 v North bridge ; 1.7 v whereas (with 1.55 the processor was stable only at 470 MHz Bus, 1.7v allowed to add a full 4 MHz :-) ) After checking to the stability it was interesting to check the processors temperature. 0.45 is not the 0.65 Q6600, the Q9400 temp was pretty good. E8600 Vs Q9400 archive , video, audio, rendering Benchmarks Super-Pi is a single threaded benchmark and here the e8600 @ 4.6 GHz showed the best result . Winrar benchmark refused to run under Windows vista. But 7-Zip was good enough. The Q9400 show the power of Quad core . In cinebench r10 q9400 is again in front, the 3.8 GHz (x4)was faster than the 4.6 (x2). Renderbench E8600 was faster with the E8600 and the 3.8 GHz allow the Q9400 to show a respectable result . But here Adobe photoshop CS4 which support multi-core processor show a nice boost. The advantage Of core 2 Quad is more than 15%. Even overclocked the E8600 can\'t catch the Q9400 – video coding is a quad core application. In audio coding the Q9400 remain completely competitive. Absolutely identical picture under science mark 2.0. The overclocked E8600 is almost equal to the Q9400 working at the default frequency 2.66 GHz. E8600 Vs Q9400 3DMark and games 3D mark 2006 just like 3Dmark vantage gives its preference to the quad core . In Call of duty 4, the same picture is observed : In Battlefield as a whole, the performance grow is proportional to the frequency. But here Far cry demonstrates a practically complete equality between the e8600 and Q9400 . Crysis in the performance regime (without AA and AF) give it preference to the higher MHz. In Grid , both processors ensure a good game play , overclocking help a bit . For Gird 3.8 (Quad) >= 4.6 (Dual) Here the same picture as above but with slight win for the E8600 . Conclusion Now we can say that many games developers introduce in their products the support of multi-core processors. The Q9400 is not the fastest Core 2 Quad processor and it have only the half of cache in comparison with high end models but its almost equal or better than the higher clocked E8600 (High end dual core). It is worthwhile to recognize that the overclocking potential of the E8600 is considerably higher and it can become pleasant for overclocker's. Generally, after adding a few dollars, it is possible to acquire the Q9550 stepping e0 with splendid overclocking potential, but this is already another story… ;) xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source we would be happy to answer for your question . if you have suggestion or comment regarding this review our support would be glad to help just join our forum and ask u will get the best answer to discuss check our forum section :-) RATE THIS REVIEW 1 2 3 4 5    / 5   View Stat
