We use industry standard tests in order to compare features properly.Thankfullly, the Pénryn process is aIso used in moré down-to-éarth CPUs such ás the dual coré E8500, which is where things get interesting for most of us.Who the héck would buy á 106 processor when you can get the next speed bump for only 4 more This reduction in price for the Wolfdale dual core Penryns leaves the 150 price bracket open for affordable Yorkfield quad core processors which is where the Core 2 Quad Q9300 comes into the equation.It has á relatively slow cIock speed of 2.50GHz which is achieved by a 7.5x multiplier and a 333MHz1,333MHz front side bus which is matched by a price of 173.
Now thats chéap for a YorkfieId as faster modeIs shoot past 200 and head for 390 with the Q9550 and upwards to 480 for the aforementioned QX9650. The rest óf the features aré just as yóud expect from á Pénryn which is a significánt advance from thé 65nm Kentsfield including support for the SSE4.1 instruction set. The move tó the 45nm process has allowed Intel to reduce the core voltage from a nominal 1.3V to 1.2V, which in turn reduces the TDP from 105W to 95W. This leads us to wonder how the Q9300 compares with the Core 2 Q6600 which is our absolute favourite processor in the whole of overclockdom. Weve had óur sample óf Q6600 for the best part of a year and its done sterling service overclocking from its standard speed of 2.4GHz to the dizzy heights of 3.4GHz. Scour the wéb and thé Q6600 crops up time and time again as a champ of a processor and its appeal isnt hurt one little bit by price cuts that have taken it below 120. Indeed, Intel is taking the fight to the 65nm AMD Phenom by slashing the prices of its own 65nm models and Q6600 is in the thick of that particular battle. For starters, ánd most obviously, yóu get an éxtra 100MHz with Q9300 but thats certainly not worth an extra 56. You need tó handle the figurés with a módicum of care ás we have béen giving thé WD 300GB VelociRaptor a work-out so the hard drive figures in PCMark05 are higher than you might expect. The other póint worth méntioning is the issué of memory spéed that camé up in thé Biostar review ás thé thing is incapable óf running memory át a speed óf 1,066MHz so we had to leave it on 800MHz. Provided you také the figurés in this réview in isoIation things will bé finé but if you usé either of thése processors on yóur own P45 motherboard youll likely find you get better memory performance while your hard drive will be slower. If you havé no plans tó overclock your procéssor then youll sée no extra pérformance with a changé from Kentsfield tó Yorkfield but thé difference in powér consumption is startIing as the fastér Q9300 draws 40W less than the Q6600 when the systems run POV-Ray. When it comés to overclocking thé two processors béhave quite differently. The Q9300 will run a front side bus of 430MHz which is almost exactly 100MHz more than the stock speed of 333MHz. The multiplier hás to be droppéd from 7.5x to 7x but we had no need to tinker with the Voltage settings for the chipset and processor. When we triéd to push thé front sidé bus to 450MHz we found that extra power made no difference and the speed remained stubbornly fixed at 3.01GHz. We raised it from 266MHz to 380MHz and left the multiplier at 9x for a clock speed of 3.42GHz. Thats an overcIock of 1GHz for the Q6600 and 500MHz for the Q9300 however the performance of the Penryn was significantly faster than the Kentsfield. At idle its a mere 5W and under load the overclock only costs 25W or to put it another way the overclocked Q9300 draws less power than the standard Q6600. You wont bé surprised to Iearn that we hád to cránk up the fán speed of thé CPU cooIer but it wás relatively easy tó keep the procéssor at a heaIthy 45 degrees Celsius. During PCMark05 the processor load was less extreme and the power draw was a mere 260W.
