    What is the FASTEST processor? And what is it's physical speed?

    Just wondering as I do a lot of burning and downloading and run a lot of apps, and usually, my PC freezes. At the moment I have a 3.2ghz Pentium 4, 2gb RAM and 160gb HDD.

    What do you mean physical speed? Clock speed is more of a marketing tool than actual performance index...

    Modern Core 2/i7/Phenom are much faster clock-per-clock than a P4, and of course have multiple cores (which should solve your 'freezing' problem and dramatically speed up task switching!)

    To answer your question, for most tasks, clock per clock, core per core, the order would be something like the below:
    Fastest:
    Intel i7 (upto 25% faster cpc than Core 2, depending on task)
    Core 2 (about 25% faster cpc than Core)
    Phenom II
    Phenom
    Core (between 50% and 100% faster than Pentium 4 cpc)
    Athlon X2
    Pentium D/4 (slowest)

    Here is a list of high end CPUs compared

    "fastest" at the moment seem to be the Intel i7 CPUs (Xeon CPUs tend to be for servers).

    There was an i7 offer posted a few hours ago

    hotukdeals.com/ite…de/

    If you do buy an i7 to build a new PC you will need a new motherboard to go with it, probably DDR3 memory, and so on.
    .

    Intel i7's definitely, but I hope you're feeling rich!

    CPUs today actually run slower (clock speed) than a few years ago.

    CPUs were getting too hot and so they had to slow them down.

    What they did was slow the actual CPUs down, but make them 2 core, 3 core or 4 core.

    So they increased the number of cores, slowed down the CPUs.

    Thats true, but getting a DDR2 motherboard and either a Core 2 Quad or Phenom would still be a very noticable upgrade from the current setup, and quite a bit cheaper...

    apparently i hear a phenom II X4 resembles fairly closely to the i7 but has far better performance/cost ratio.

    Its a good, well priced CPU but still a distance behind Intel's highest-end offering in terms of maximum performance (particular when overclocking etc. comes into play). Also for some tasks the hyperthreading reintroduced on i7's can be very effective (although not that much on a computer can really utilise 8 cores - at the moment anyway...). If money is no object, definately go the i7 route, but where it is I reckon either Phenom or Core 2 Q paired with DDR2 are still the best performance-per-£ options...

    nope ath x2 far faster than core.. the original intel dual core cpu's were terrible.. jfyi

    physical speed, as fast as you can run

    The original intel dual core cpu's were not Cores - they were Pentium 4 dual-cores, completely different. The Core is based on the Pentium M, which itself was based on the P3, and clock-per-clock it does outperform the Athlon architecture in the majority of tasks (dependant on cache sizes obv.) - not by a large amount, but a bit.

    Not where the mem controller comes into play, which it does more than you would think.. and i never said 'core' was the original intel dual core cpu, i said ath 64x2 were faster than core cpu's and that the original intel dual cores were terrible (considering the ath64x2 were amd's original dual core that goes to show why they were leading till c2d destroyed them)

    and yeah i7 is the way to go.. got my 920 running at 4ghz and it eats everything i throw at it.. blu ray encoding to 1080p h264 8.4gb mkv in 3hrs anyone? :-D

    I have a 3800+ X2 (2GHz) in the desktop and a 1.8Ghz Yonah (Core Duo) in the laptop and for the majority of (32bit) CPU-heavy tasks the Yonah is probably quicker - not by much, but the desktop certainly isn't far faster. Its a bit of a pointless debate anyway as the Core was never a desktop CPU anyway - nearest thing is probably the Penitum E which is more of a bastrdised C2 than a Core...

    Not really - the slowest i7 can trash the fastest Phenom, cost and performance-wise they're on par with the C2Qs. If you want the best performance the i7's are the only choice and pricewise are getting better as the platform cost comes down. The performance/cost ratio is always going to drop the higher up you go in performance.

    yeah your probably right as they were both murdered by the core2 chips.. and i have the same setup (3800x2 server and 1.8 core lappy..my mothers.. and the server is def quicker at h264 vid encoding, but may be slower at other stuff..) its academic really as the question was bout fastest chips.. so yeah the i7 extreme at stock or a 920 (mine) oc'd to 4ghz on air... the thing FLIES! :-D

    Its probably the HDD thats the biggest bottleneck in video encoding, not the CPU (or memory) - laptop HDDs (especially 5400s) simply can't keep up...

    I may go for a custom built PC from eBay, under £350, with a Q6600 processor

    Why not build it yourself? Its probably easier than you think, a good learning experience and you get to pick and choose exactly what you want...

    Original Poster

    Because it would be much more expensive...lol

    Is an Intel CORE 2 QUAD Q6700 processor any good?

    Yeah its a good CPU - not the newest or fastest, but a big step up from a Pentium 4. Costs about £150 or so...

    how could it be more expensive?
    surely if you buy off ebay-
    a) it might be second hand (ok a bit long shot)
    b) no warrenty for most of the components (with the builders? i have no experience so cant comment)

    Also if you look for builders off ebay, they tend to use generic stuff (like ram) rather than branded ones which is one of their ways of cutting prices, and imo, they are more risky.

    I'd be careful of ebay, you're likely to get low quality parts and no operating system. If you want a custom built PC and don't want to do it yourself then there are plenty of established companies like cyberpowersystems and pcspecialist who'll build it.

    Anyway, back on topic.

    What makes you think it's the processor that's at fault? Have you checked how much processor is being used in task manager? Disk burning and downloading aren't particulaly processor intensive, and a slow processor should just cause them to go slower rather than freeze (by 'freeze' I assume you mean the whole system becomes unresponsive rather than just one or more of the tasks pausing for a while).

    Unless you've got good evidence it's the processor I think a far more likely candidate to be behind you freezings is the hard drive. Both downloading and burning use the hard drive and the hard drive being accessed a lot can cause the whole system to freeze. The bad news: A faster HDD won't help much, that's just how HDDs are. The good news is that there is now a solution, an SSD. However, SSDs are expensive, the current pick of the crop is the Intel X25-M which is £300 for 80GB. There are cheaper ones, but you have to be careful where you tread as quite a lot of them (especially the ones with the JMicron controller) have freezing problems of their own. The OCZ vertex is apparently worth looking at, that's £170 for 60GB and £320 for 120GB.

    Remember its a single core P4 CPU (I assume from the title, anyway) - good for single jobs but not suited to multitasking. I'd get a new, balanced system with a multicore CPU long before I thought about SSDs (the power savings alone from leaving P4 behind will almost pay for themselves!).

    If you want it for crunching and don't mind spending a bit this will set you back about £800 including quidco but will benchmark over 7000. Business contract machines and are as new. Not great as an everyday machine though and don't look at your electric bill!

    It's a Pentium 4, not a 386 running DOS. While dual-core does have it's benefits I doubt you'd find multitasking speed is one of them, although a quick look doesn't show anywhere that has tested it.

    Anyway, my point is that downloading is limited by internet speed and burning a disk is limited by the drive & disk speed. If the processor isn't being run at full capacity then the problem probably isn't there and buying a new one is unlikely to help.

    OP stated "I do a lot of burning and downloading and run a lot of apps"

    burning should not really be that affected by cpu speed and neither should downloading.

    depends what apps you run as to what is freezing your PC. Bring up task manager and sort by cpu resource usage to see what app is hogging the cpu.
