  1. Intel Core 2 Extreme QX9650 review

    Intel Core 2 Extreme QX9650 review

     

    Intel has taken the wraps off its new flagship 45nm quad-core processor, the Core 2 Extreme QX9650. And that can only mean one thing - a chance to bang on about Moore's law. Again. Well, that and a new performance leader in desktop computing

    In real terms, quad-threaded applications are thin on the ground and will be until at least this winter. So, in most cases, this keeps a more or less even pace with its dual-core equivalent the E6600

    This is Intel's new biggest hitter. It's still the Kentsfield core, but an FSB raised to 1,333MHz bumps the clock to 3GHz. For that hike, you'll need a motherboard supporting a bus of 333MHz or greater, which means an Intel P35 or an NVIDIA 680i

    Four cores at 2.93GHz and enough headroom to take it to 3.4GHz before it gets whiny. That's 555 fps in S.T.A.L.K.E.R at 800x600 (and 620 at 3.4GHz) - the next best is the Q6600 at 454.

    A fine chip to be sure, and the Core 2's last gasp before the Intel performance-to-pennies juggling act really starts to fall apart. With the E6420 turning up for just over £100, the extra £30 on the asking price for this becomes hard to justify

    Making a slightly harsh call as to which Core 2s to limelight in this test, we've elected to politely show the 1.8GHz E6320 the door. It's been a pleasant house guest, but just a tenner more nabs an E6420 with nearly 300MHz extra on the clock.

    This is the baby of the bunch (unless you count the 'Pentium Dual-Core' range, whose 1Mb cache means it's not as well suited to gaming). This, though, is the very definition of sweet spot. Available for just under £75 online, that's barely real money

    Context. That's what Intel's latest processor is all about. On the one hand, this is the fastest CPU in Christendom. Courtesy of four cores, each one benefiting from Core 2 architecture, the QX6800 isn't just the weapon of choice for multitasking.

    Intel Core 2 Extreme QX6800 review: Has Intel been sandbagging with its sickeningly successful Core 2 Duo processors? It's a tempting conclusion to draw, even with the launch of this new Extreme QX6800 model, the most powerful Core 2 chip to date

    The first Centrino release provided the first consensus of targeted mobile computing improvements - battery life, wireless connectivity and overall performance. Now it's been updated, promising to break new ground with a host of exciting new features

    Adequate dual-core performance at an affordable price? That'll be the Pentium D 820. It may be produced using relatively ancient 90nm manufacturing technology and based on Intel's soon-to-be-extinct Netburst architecture

    Six months ago, Intel blew our socks off with its new Core 2 Duo processors. So what is the standard bearer of the range doing languishing near the bottom of the table? The answer is simple and it has to do with that old chestnut, value

    Has Intel jumped the gun on quad-core computing? Well, it's certainly true that many of our benchmark results fail to demonstrate any benefit to quadcore CPUs. In fact, it's clear that Intel's new Quad chips are actually slower than their dual-core rivals

    Nearly £150 for an extra 200MHz. If you're of the opinion that that sounds like a pretty rum deal, then join the club. Unlike its Extreme Edition sibling, the E6700 can't even claim to offer the dubious benefit of an unlocked CPU multiplier

    And so to our winner. In most regards, there's little to choose between this and the more affordable E6300 Core 2 Duo model. Both are specified with the more compact 2MB shared cache memory but still produce respectable performance

    Previously, we've placed the baby of the Core 2 range at the top of the pile when it came time to dole out the awards. After all, why pay more when this chip can deliver nearly as much grunt as an Extreme Edition chip costing six times as much?

    Give it up for Kentsfield, the first ever quad-core CPU for the desktop PC - four processing cores, a quartet of software threads and a whole mountain of processing power.
