Regardless of the victorious procession of processors carried out by LGA1156 on the computer systems of many customers, the nice previous LGA775 socket just isn’t going to surrender but. After all, within the high section of the market, these processors don’t have anything to do – in comparison with Core i5 / i7, they ceased to be absolutely aggressive. Nonetheless, it accounts for a moderately low quantity of gross sales, however within the extra large segments amongst Intel merchandise there are not any options to the “previous” Core 2 Duo and youthful Core 2 Quad fashions – the dual-core Core i3 / i5 and Pentium will enter the market solely in January. Then it’s going to take a while to attend for the saturation of the buying and selling community with these fashions, then the mass look of cheap motherboards (in precept, they exist already, nonetheless, for the previous six months, for apparent causes, producers have centered on high fashions) .
Sure, and many don’t wish to clutch at new merchandise, on the danger of getting burned, preferring easy and time-tested options. As well as, many customers have already got techniques primarily based on LGA775 processors, so they’re extra drawn to the potential of a “little blood improve” than the concept of a complete platform change. Subsequently, even when these processors are not of curiosity for analysis, it’s nonetheless needed to check them. No less than in an effort to absolutely evaluate with the anticipated information 🙂 even when these processors are not of curiosity for analysis, we nonetheless want to check them.

The final time we addressed the subject of Core 2 Quad was in late August, and a few representatives of the Core 2 Duo and Pentium households had been examined in mid-October. Some, however not all – particularly, we weren’t in a position to get the senior C2D, specifically the E8600. The Pentium line additionally managed to be up to date by means of the discharge of the Pentium E6500, which got here near the magic mark of three GHz, as soon as accessible solely to overclockers or consumers of maximum processors (for instance, Core 2 Excessive X6800differed from our hero solely within the technical course of, TDP and cache capability). The Pentium E6600 anticipated within the first quarter of subsequent 12 months will typically exceed this line, on which, apparently, it’s going to put an finish to the event of this line. In the identical manner that the E7600 and E8600 (the latter – precisely, the previous – with a 90% chance) closed their lineups.
The Core 2 Quad line has additionally been up to date, though it may be thought to be a step again. Alternatively, the C2Q Q9505 additionally dangers quickly remaining the quickest within the household – extra productive fashions are outfitted with a 12 MB L2 cache, which may be very costly to fabricate, however they lose to the extra technologically superior Core i5 750. Clearly, not residents 🙂 The brand new processor could be extra logical to name the Q9500, nonetheless, the corporate most well-liked such an authentic model, emphasizing that the novelty differs from the already long-released Q9550 solely in diminished cache reminiscence. Nicely, at a value, after all. So right now, actually, we’ve got the “swan track” of processors underneath LGA775 – a check of the tops.
On the whole, every little thing has already been stated about the principle characters – along with the Core 2 Duo E7600 examined final time (which we determined to incorporate among the many essential members) these are the tops of the respective households. Somebody has already taken this place, somebody has but to do it, and most processors will go into oblivion unsurpassed 🙂
The collection of processors for comparability additionally didn’t represent particular issues. Clearly, Q9550, the closest analog of Q9505, couldn’t assist however enter it. We couldn’t ignore the Q8200 – the most cost effective Intel quad-core processor. And at last, the Core i5 750 – it seems considerably “out of competitors” (though not fairly – the worth is comparable with some members), but it surely’s fairly appropriate for the position of the “higher bar”: you possibly can instantly assess whether or not it is smart to remain dedicated to the previous platform or it’s time emigrate already.
AMD’s “company from the camp” are additionally three right now. Intel’s “household” turned out to be very mottled, so we determined to not choose rivals when it comes to value and different positioning, however to restrict ourselves to already well-studied representatives of the price range Athlon II household: X2 250, X3 435 and X4 630, that are additionally peculiar “tops” rulers. The primary two are designed to discourage potential customers from shopping for Celeron, Pentium, or the youthful Core 2 Duo, whereas the latter line may be very peculiar: the most cost effective quad-core processors that should not have direct analogs within the Intel vary. However no person bothers us to check all of the named processors, so we are going to do it. It might be attainable so as to add to this group numerous “Phenomas”, happily, even the oldest mannequin of this household (Phenom II X4 965), after the final value discount, turned out to be a competitor to the “semi-budget” Q9505, however we won’t do that so as to not enhance the charts to a completely indecent type. All the outcomes, historically, are in our desk, however for many who favor the normal graphical type of presenting data, we are going to make a corresponding reward with out detailed feedback (definitely not later than the “previous” New Yr).
Even supposing the transition to DDR3 is the mainstream of the pc business, and for some DDR2 processors it’s already bodily unimaginable to make use of, this time we determined to step again a bit and Core 2 Quad Q9505 to check and along with DDR2. The very fact is that we didn’t check the Q9550 with DDR3, however we have to evaluate these processors in probably the most shut circumstances (and the Q9300, which is a type of benchmark for the present model of the method, was beforehand examined solely at the side of DDR2). Alongside the way in which, we can even study one other attention-grabbing query: the affect of several types of reminiscence on efficiency in actual functions. The FSB 1333 frequency right here is simply probably the most attention-grabbing: since DDR2 stopped at a barely decrease stage, formally DDR3 will get a slight benefit in bandwidth. The truth that it can’t be put into follow,
The efficiency testing methodology (listing of used software program and testing circumstances) is described intimately within the article . For ease of notion, the outcomes on the diagrams are introduced in p.c (the results of Intel Core 2 Quad Q9300 in every of the checks is taken as 100%). Detailed leads to absolute values can be found in desk format in Microsoft Excel format .
No one offers the chance to broaden “at full energy” to the quad-core processors, so it’s not shocking that high-frequency dual-core processors are the only option. That is very true for the Core 2 Duo E8600, the place the frequency of the cores and cache, and the amount of the latter too, are very excessive. However the E7600 towards the background of the E6500 doesn’t look excellent: the distinction between 2 and three MB of cache just isn’t radical, however the frequencies in these households are getting nearer and nearer to one another.
That’s when the cache capability is twice as completely different (as within the Q9505 and Q9550), at the least one thing will be stated. Though it may be seen that the contribution of the twofold distinction within the cache capability on the identical frequency is simply equal to the launched pair from the rise in cache by megabytes and the frequency by 133 MHz in youthful fashions. DDR3 outcomes worsen however insignificantly – towards the final background, the distinction between the sorts of reminiscence will be thought of insignificant. For apparent causes, AMD Athlon II processors are losers right here even when we evaluate them with Pentium – extra cores don’t give something, and there may be not sufficient cache reminiscence.
