AMD phenom II X6 hexacore vs Intel i7 quad HT

[WhiteFireDragon]

found out my AM3 is not compatible . i just wanted it up and running for the supercomputer week, now it's just sitting here. to get it working on the mobo, does that mean i have to buy a cheap am2 chip to flash first? best option is probably to just get another mobo

[jcool]

No problem. I've never saw the date that way with the day first on the Device Statistics page. Also, I made a correction to my earlier post. Those are the totals for each machine, not just daily. To find out what each machine did today you need to click on the device name.

Yep, seems like display format adjusts automatically, depending on where the member in question lives
Here's mine, for example - German format

Wow, I have got to turn HT on for my i7. At 4.2ghz HT off it produces the same heat as around 3.9ghz HT on. It made almost no difference when I was folding and I had been gaming a lot so I always had it off.

I have only been hitting 20,064.87 PPD

[jcool]

On a Core i7, HT on boosts WCG performance by about 40% over HT off - so yeah, turn it on, even if you have to back down the clocks a little.

[shoota]

have we decided which one gives more ppd/watt? i7 or thuban?

[Biker]

I have only had my X6 running for two days and it is only clocked at 3.8 but it is pumping out the WU's nicely

I'd say clock for clock the 920 just edges it in ppd but the X6 runs a lot cooler...

[shoota]

right i get that it the i7 edges it out and all that but i'm concerned about the power each platform uses. i'll trade a few ppd for a less power usage if that turns out to be the case

[Biker]

Well that is just the thing....

The X6 uses a higher vcore (1.36v @ 3.8) vs the 920 (1.18 @ 3.8) but it definitely pushes out less heat....

Conclusion: Slightly higher power consumption for the X6 but a cooler farm

that may not be the case since they're different platforms. AMD generally has a higher vcore reading from cpuz, but that doesn't guarantee it to have a higher power consumption. if it runs cooler, logically it should have a lower power consumption.

dam i wish i had mine running . i picked the wrong AM3 mobo, and now both my thuban and mobo is sitting doing nothing.

All power use eventually turns to heat so that's not possible.

Yes it is possible.

The only possibility is that the X6 is more efficient (less heat output).

I know.

I was suprised too!

[Sparky]

You can have a higher voltage but lower power usage. Higher voltage does not directly equal more power consumption.

[Gonzalo-Gonads]

Voltage X Ampage = Power consuption (Wattage)

The x6 might need more volts but not as many amps!

I am running both setups, albeit at different Mhz, but I think that if they are at the same Mhz and the ram and other items were the same it would be pretty damn close. From a cost stand point the AMD wins out since you can get a $60 MB with built in video and only have to use dual channel ram versus triple, so it can add up to quite a bit of upfront coin in savings going AMD. I think AMD is starting to get competitive again, although from a strictly performance stand point the I7 x58 is the top dog still, but the AMD platform is definitely one to consider on a budget.

[radaja]

you can run dual channel with i7 too.ive got my i7-920 running
with the g.skill 2200 Pi's 1156 2x2Gb kit.

now that's the post i needed to read! thanks

I'm getting a better idea of PPD production now after several days of running Bionic at stock speed +2600 NB. I registered a few days before running so I have to divide total points granted by uptime - time from last update.
Running 32 bit Bionic -sorry 'bout that
No errors, invalid, aborted or inconclusive.

To put it in a nutshell, what's the verdict?

[Vapor]

Early numbers have Thuban at ~6.7PPD/MHz while a Bloomfield/Lynnfield can do ~8.7PPD/MHz. Means a Thuban needs a 30% clock advantage to just match a Bloomfield/Lynnfield (with HT)

Factoring in power consumed and a Lynnfield+HT probably just dominates even more.

[shoota]

i saw an i7 860 on craigslist last night for $199. not a bad then huh?

[D_A]

Yeah ... depending on what's happened to it.

That was a 920 at stock 2.6Ghz, so if you leave it at stock and bump the 1090T (1055t) up to 3.3Ghz for the 30% advantage they would probably be about a tie both in output and power consumption. Then it comes down to overall cost and that's where I think AMD has the advantage. Yes, you can run the 920 with dual channel, but it was not designed for that and the cheapest MB that will run a x58 is $150 while the AMD is backwards compatible and you can get a MB for $60. The reality however is that the 920 can be overclocked to 4.2Ghz blindfolded which should give it a big lead based on your numbers and the 1090t or 1055t would have to be at 5.5Ghz to match it and that's not going to happen under water much less air. So I would say that from a pure output point the I7 920 definitely dominates, but it comes down to total cost, which is why I stated that the AMD has the advantage. For roughly $200 more than the AMD you can get into an I7 920/x58 setup, but that's still a lot of coin, especially right now.

Gotta wait for another while for the results to be averaged out.

Check i7 860 vs. 1090t....

i7 860 has the same perf as a 920 for crunching, but Lynnfield and P55 are thriftier than Bloomfield and X58 for power consumption. Lynnfield+HT is a sweet spot right now for PPD/watts/cost, IMO.

Thuban is a good improvement for AMD (afterall, clock-for-clock, a Clarkdale basically ties Deneb and does it at a fraction of the power), but a Lynnfield without HT can almost match it in overall production a day and consume less power (and arguably be as cheap as basic 1055t + AM3).

For WCG, AMD is simply behind.
