    Intel core 2 extreme QX6800 review

    6  

    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

    This is as good as it gets for AMD in the mainstream, but previously we've given it a smack, due to a £300+ pricetag. With it now showing up as low as £115 online - a tenner more than the 400MHz slower 5200 - a public flogging is no longer in order

    Unlike the 4600 and 3800 below them, the 5200 and upwards haven't chucked a meg and a half of cache over the edge in a desperate attempt to lose cost-weight. This still carries a full 2MB of L2.

    AMD's fallen upon hard times lately: this sub-£70 chip went for £120 just three short months ago, for a start. The better news is that, with Core 2's high-end action largely revolving around quad core, the 4600+ hasn't slipped in the rankings any

    Life always finds a way. Find a rock in the Core 2-ravaged post-apocalyptic processor wasteland, peer under it and look! There's a little 3800 cowering from the light. Less than £50, a mere 2GHz and 1MB of shared cache, yet still it survives.

    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

    here's a temptation to bend the truth when discussing AMD's recent offerings. It's the same sort of misguided pride that compels people who've just seen the Rolling Stones creak across some gigantic arena to say "yeah, they've still got it"...

    Intel's four core Kentsfield processors have been out for a few months now, but we're still at the very early stages of the quad core revolution. Supreme Commander will be the first game that can make use of four separate CPU cores at once

    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

    The launch of Intel's Core 2 processor was a rude shock for AMD, at the time happily extracting top dollar from PC enthusiasts for its Athlon 64 X2 dual-core chips. Now you can buy this mid-range X2 for just £123

    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?

    When AMD first launched its X2 range of dual-core Athlon 64s, they were comfortably the most desirable CPUs on the planet and boasted untouchable multithreaded performance. Today, this flagship chip has been left high and dry

    Life is tough for the 3800 plus. This is the single-core, non-X2 variant of the 3800 which boasts a lone cache memory pool of just 512K and runs at 2.4GHz. And very definitely not to be confused with the Athlon 64 X2 3800 dual-core processor

    Since Intel wheeled out its new Core 2 processors, it's been a bruising time for AMD. If the clear advantage in performance and power consumption parsimony of Core 2 in dual-core trim wasn't bad enough, Intel unsheathed the quad-core Kentsfield revision

    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.
