Which cpu is better for the money. The phenom ii 720 or q6700. I'm guessing that the phenom ii 720 is nearly as good as the q6700, or not really? After all i think the gap is 300mhz before they're about the same and the q6700 has 0.5mb more cache. For mass multitasking i can bet that the q6700 is better?

I bought a phenom ii 720, also about the comparison, i'm thinknig about both the processors running on a ddr2 motherboard with 800mhz ram.

the q6700 is £125 i think ore or less and this phenom, well the one i got for £110. But then looking at the results here the q6700 and pii 720 are very close, and the 720 beats the q6700 in a number of tests i mean for gaming.

At that price, for my use which is transcoding, video editing, F@H, image editing and some gaming, the Q6700 would definitely be the CPU I'd chose (they're pretty much the same price there).

In fact at that price there is no reason to get a Phenom II X3 720.. the Q6700 is the better CPU unless you do nothing but game.

But then, you have to concider the motherboard as well, i think am2 motherboards tend to be cheaper. But then intel overclock much better i hear the q6700 can overclock to 3.6ghz easilly is that true? What stock voltage overclock can it get to? With the pii 720 it's 3.2ghz from 2.8ghz. Look at this benchmark though.

hmm for gaming, the score seems to be quite close, but for multi-tasking the q6700 drifts of from the pii 720. (Faster) And then they overclock more, the score difference doesn't seem to be much, but it seems i aught to have gone for the q6700, but then i don't think that says that the pii 720 is completely worse off.
Maybe overall i might have saved more money going for AMD and getting a cheaper motherboard than for intel, since all of intel socket motherboards are just generally more expensive?

Socket 775 motherboards aren't that bad, price wise, but they are at the end of their life expectancy (there won't be any new CPUs released on the socket 775 platform AFAIK).
November 10, 2009 5:08:18 PM

but then what about am2? Could there be more future processors for that, and my motherboard has a 95 watt limitation as well, amd make ppor processors in terms of energy efficiency. I mean processors better than the pii 965. I think that ddr2 will get outdated and they will make new processors that will only work on am3 do you rekon that's possible? In 2 to 3 years.

AMD2 is also EOL.. in fact AM3 likely won't get many more processors either (some 6 Cores and then it's Bulldozer).

November 10, 2009 5:46:14 PM

Get the Phenom II with an AM3 mobo. The Q6700 is a better chip due to having an extra core and for that reason alone.

Not sure where you are getting your info from Elmo but Thuban will fit in AM3 mobos, and the current talk is Bulldozer will as well. Thats a future 8 cores if you get a decent AM3 mobo.

775 is deader than a dodo.
November 10, 2009 5:47:16 PM

i don't think i'd want a six core though lol. But would that still benefit 2 core optimised games? Because of the actual technology? I have the feeling first person shooters will most likely stay dual core optimised. As in they use up 2 cores mainly maximum but the other cores are used briefly which adds to the speed of the game. Crysis is a good example to use. For the e8600 which is 3.33ghz it scores very well and beats 2.9 - 3ghz quad cores. But then do you think the new processors such as the 955 will be reduced in energy consumption requirements, such as to 95watts from 125watts. As time goes on or do you rekon it is unlikely?

I think more cores will become more important as windows 7 takes over from windows xp.

I think you'd be better off getting a cheap tri-core now with the option of upgrading to 6 or 8 cores in future, compared to getting a quad-core now that has no upgrade path at all.

The q6700 is faster in most tasks, slower in gaming but nothing you will notice either way.

November 10, 2009 5:50:29 PM

And yes the 955 will be 95w soon, probably within 2 months.
November 10, 2009 5:55:07 PM

will it still be black edition or not really. If not then that's a bother. I don't feel like upgrading my motherboard, it's not bad and it's certianly not cheap or old. I already have the phenom ii 720. I have vista home premium 64 bit as well. Is windows 7 actualy more demanding for specs than vista is? I thought it was meant to be more efficient and wasn't such a ram consumer as vista is. As in Vista used over 1000mb of ram just for being on in the first place.
November 10, 2009 5:58:20 PM

do processors actually have a certian point for a game where they can give no more FPS regardless to how powerful your graphics card is? Such as having a single core intel pentium at 2ghz lol and a HD 5870 compared to the same cpu with a GTX 260?

hahahaha "hello son, there's your problem" bullet or drill holes.

So you think that there's not much difference then? That there isn't too much significance between them?
November 10, 2009 9:24:36 PM

The q6700 is a quadcore, the 720 is a tri core.
The price difference is huge, so you can even pick a Phenom II 955 and make that Q6700 look like poop.

Gaming wise, it will perform same or better as i7.
Task wise, it's around the Q9650 performance (or 9450 I forgot)
Get a AM3 mobo also, DDR2 memory prices have gone crazy.
AM3 will be the socket for new 6 and 8 cores, so your better of with it.
I personaly recomennd the M4A785TD-M EVO if you have a single GPU.
November 10, 2009 9:30:43 PM

didnt really understand what you meant but yes, upgrading to phenom II 955 will show great improvement in games.

Oh and didnt see that you didnt want to change mobo...but that was just my 2c xD

If you have already bought the 720BE, then buying a q6700 would be a waste of time and money.
One note of caution, if your mobo has a 95W limit, you'll need to strictly limit any overclocking.

Here's a comparison of the 720BE and the Q6600: http://www.anandtech.com/bench/default.aspx?p=53&p2=83
The Q6700 was not an available choice. Although the 720BE wins a few, the Q6600 wins a lot more. Still, I don't think the differences justify switching to the Q6700 if you already have the 720BE.
November 11, 2009 9:16:41 AM

no i'm just saying, at the beginning if i were choosing between the phenom ii 720 and the q6700. The pii 720 is cheaper and i think faster in games like Left For dead than the q6700. But i think overall aught i have chosen the q6700?

November 11, 2009 9:25:46 AM

That's still a tough call. If you're never going to upgrade, the q6700 would be the better choice. If you might upgrade, only socket AM3 has any real hope for that. New features like USB 3.0 may never appear on a S775 board (but you could get an add-in card). If you use mobo RAID, the odds of finding an exact replacement if your mobo croaks is a little higher with AM3.

Why Q6700? Q6600 is much better perf/dollar.
November 11, 2009 10:04:04 AM

Does that mean am2 is going to become obsolete soon? Further new processors won't work on it? But then at least the pii 955 will become 95 watts and that's a good processor, but i'm sure that these quad cores will be going on for a long time so am2 should be alright, even for very high end gaming wanting good frame rates?.

November 11, 2009 10:24:43 AM

Yes a Phenom II 955 with AM2+ mobo will be more than good enough for gaming, certainly superior to a Q6700.

The 6 cores might work with AM2+, we don't know yet for sure.

November 11, 2009 10:44:27 AM

I have a am2+ board. I thought in a way, am2 was better to buy because, the ram costs cheaper. But apart from ram, this HT link issue, an am3 cpu can't really be that much slower on a ddr2 motherboard compared to running on an am3 motherboard? Is it at the most 5% less performance, not concerning ram. Anyway, ddr2 800mhz ram is as fast as ddr3 1066mhz ram. it doesn't really say much about am3, i would have only ultimately have seen a performance increase if i had bought 1600mhz ram and the performance increase is very minimul anyway. Someone says that i shouldn't overclock too much with a motherboard with a 95 watt limitation. Does that mean all 125 watt boards regardless to how much they cost aught to overclock more than my board with the same chip?

For a gaming rig? No, there's little difference between the two at decent resolutions because your frame rates are limited by your graphics cards anyhow. Certainly nowhere near enough under any circumstances to dictate buying a new motherboard if that wasn't already in your plans. So if you have an AM2+ motherboard already, just buy an AMD processor and be done with it. If you have an LGA775 based mobo, then buy the Intel.

November 11, 2009 1:55:14 PM

so that's a real genuine shot through processor lol? I can't believe it to be honest i would have though the whole processor would have been split in half. Also i wonder how the processor would have been clamped down when shot at lol.
Most likely you are joking and i know i'm going too far but i like to keep a conversation going.

Also i wonder if anyone has got any information on these new energy efficient processors coming out; the pii 955 being turned into a 95 watt cpu. I'm wondering if it will still be a black edition, i like overclocking processors up to their full potential on stock voltages. My pii 720 i have at 3.2ghz. Someone told me that when you overvolt a cpu the life expectancy goes down by alot, is this so even if the temperatures of the processer are still low? I got low temperatures still when i overclocked the pii 720 to 3.4ghz with a bit more voltage added, it still didn't go above 54 degrees. Also i suppose pii architecture is 45nm as opposed to core 2 quad which varies. But that means bot all as a 65nm intel cpu can still be better than a 45nm amd cpu with the same amount of cache, and even if the amd has 100 or more mhz?

Nash - Not kidding about the bullet holes in the processor. The pic came from an article here on Tom's last April 1st.
November 11, 2009 2:42:04 PM

o right. The gun that shot through it must have had penetration attribute rather than damage. Would you say so, i would have thought that it would have split in half. The processor must have been pretty stong to not break up into pieces you know what i mean? Show me the article.
November 11, 2009 4:55:36 PM

lol, that post is soo ridiculous. Shooting at cpus and talking about guns which have pretty much nothing to do with what tom's hardware is about lol. But it is interesting though. I didn't know amd processors were soo strong.
November 11, 2009 4:58:31 PM

that's really impressive. After all it's penetration that is the real deal. The damage looks soo smooth, so it gives the impression that the gun is very effective and can penetrate through a lot of material, almost like a laser.

Yes, if you exclude the fact that Q6700 is garbagy old architecture that will struggle on newer tasks; if you exclude the fact that if you get 720 you have great upgrade options and, with the right motherboard, can unlock the 4th core; if you exclude the fact 720 is miles better in 90% of the applications that don't use four cores. Yes, if you exclude those, Q6700 is better. I really don't know why people even consider Core2 these days...

November 11, 2009 5:53:34 PM

however where i'm looking at the pii 720 and q6700 are similarly priced. But then intel board generally cost more don't they. Also isn't the phenom better at games optimised for two cores? That means the majority of games apart from Far Cry 2, which benefits just a bit more with the q6700. I' m not really much of a multi-tasker but a more of a gamer, and would you say that out of 10 games that are dual core optimised, the pii 720 should beat the q6700? because i know that core 2 are usually better than phenom ii by 200-300mhz, as in you'd have to have a 2.8-2.9ghz phenom processor to match a 2.6ghz core 2 processor. Also comparing core 2 q6700 with the phenom ii 720, both cpus using ddr2 board and 800mhz ram. I would think then the q6700 would come closer and beat the pii 720 in games like left for dead where benchmarks have been put up on this site.

also i bought the am2+ xfx 8300 darn thing instead. 95 watt cpu limit. But makes sense in my smaller case.

Uhm... Phenom II has a newer architecture than Core2 and especially Kentsfield Core2, making it considerably faster at any clock speed. Truth be told, Q6700 will still be faster in quad optimized games and software, but they only make small amount of the world's software and, as I previously mentioned, you have a chance of unlocking another core which will make your CPU miles (MILES) better than any Core2.
November 11, 2009 6:02:43 PM

i can't with my processor. I heard that it can't be done on an nforce motherboard. Also, you know the benchmarks on here, i feel they might be a bit one sided, since the amd processors will be tested on an am3 board when the benchmarks for games have been done. Also what about the ram speed. Do you know what the test set up is for the tom's hardware cpu benchmarks 2009? But either way, aught my phenom running 800mhz ram compared to a q6700 running 800mhz both running on a ddr2 board, beat the q6700 even still at games like left for dead such as represented on the benchmakrs here?

could we stick with the point. I want to know if the new energy efficient phenom ii 955 will be black edition, when it comes out. Someone told me not to overclock with my board because it has a 95watt cpu limitation. Does this mean that all 125watt motherboards are better regardless to their price compared with my motherboard? But my motherboard was not cheap; £100. Has a wopping size heatsink as well for matx.
