SYSMark 2007 Performance
Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.
The Core i7 860, as expected, falls right in between the i5 750 and the i7 870. The overall performance impact of slightly faster clock speeds and Hyper Threading is small, it's only in the individual cases that you see large gains from the feature. Most applications have difficulty stressing four cores, pushing eight threads isn't any easier.

http://www.anandtech.com/mb/showdoc.aspx?i=3639">http://www.anandtech.com/mb/showdoc.aspx?i=3639 - 1600 C7 on both platforms, 6GB for X58 and 8GB for P55, it does not make a measurable difference in performance compared to the 4GB setups.Wwhat - Sunday, September 20, 2009 - link
Anand does indeed use 1066 RAm for the i920 and 1333 for the i860/870/750, but those are the numbers intel specifies them at as you can see on intel.com, now the problem is that people don't use it with such RAM but with 1600 or higher, and also that if you compare the 2 it would be nice of you also compared them with at least equal speed RAM, and when you would use setup that the average guy that builds his own system then you'd get completely different results.So I guess anand is reviewing for businesses who take what they get on the cheap, pre-made systems with 'stock speed' RAM

"If you clock them at the same rate, with the same uncore, it's only ugly for the Lynnfield. "That is not the case. Actually, overclocking uncore speeds makes very little if any difference unless your application of choice is SuperPi or one of the older 3DMark benches where you can realize some measurable differences (wow, look I gained 0.84 seconds in SuperPI 32M and 27 points in 3DMark06) in the results.
Anyway, Lynnfield will clock both uncore and memory significantly higher than Bloomfield so I have a hard time understanding your comments about this subject. If you do not like Lynnfield, that is fine, but the continued comments about inferior memory being used or uncore rates or turbo modes (which the 920 is running by the way and is inferior to the 860s turbo mode) is really wearing thin at this point.
I already showed the results with DDR3-1600 C7 and nothing changes at DDR3-2000 C7, except VTT/VDimm is much lower on Lynnfield than Bloomfield for equal memory clocks.
For a daily platform, I would take the P55/860 over the X58/920 any day of the week. It simply performs better in most cases and uses significantly less power to do it. In fact, if based on just SOHO computer usage and typical gaming scenarios, I would take the 790FX/965BE over the X58/920. For just a SOHO non-gaming system, I am going 785G/Athlon II all the way.
For benchmarking, I will go with the X58 platform, but even then you have to ask yourself why. Unless you have been provided with cherry components and have a limitless supply of LN2 for setting records, there is not much point in using this platform now unless you are in the workstation arena where future processor upgrades will make a difference.
The only other advantage is in multi-gpu gaming, where the X58 will make a difference in the benchmarks. However, you will not notice the difference between the two platforms in blind A/B gaming comparisons. I know, I tried it on a few users who own X58 platforms. ;) Once again, the vast majority of gamers do not run CF/SLI so even this small advantage is a moot point for most, especially when you consider the performance of the upcoming GPU releases.
The X58/920 consumes significantly more power and performs about the same if not worse at times than the P55/860. So, unless you have two very specific needs for X58, there are great alternatives available from both Intel and AMD. That is the crux of our message in these articles.

Gary,you have mentioned a few times that Lynnfield uses significantly less power, and obviously at stock settings that is true. But if additional voltage is needed for overclocking, that advantage would seem to disappear. Do you have any tests done to show both platforms at higher clocks? Or how about both at their maximum clock with turbo still enabled, to see if you can save some power while still getting a similar end clockspeed when needed?
Gary Key - Wednesday, September 23, 2009 - link
We will have an article shortly on power consumption (static) with Lynnfield and Bloomfield overclocked. Just to cut to the chase, Lynnfield wins by a clear amount, even with slightly higher voltages on the CPU.strikeback03 - Thursday, September 24, 2009 - link
Cool, thanks.TA152H - Saturday, September 19, 2009 - link
Gary,Would you care to prove any of this? It looks to me on your own bad benchmarks, you run the Lynnfield at higher voltages and higher uncore.
Where is your proof the Lynnfield can clock the uncore higher? Why did you clock them differently then? Where is your data supporting this?
Your remark about turbo was beneath even you. I never complained about turbo modes, except in the context that people here will overclock, and make them irrelevant. I have said repeatedly, against the bashers, it's a nice technology. But, it doesn't show the architectural differences, which a lot of us were curious about. Did you forget you are supposed to be 'tech' site, not PC Magazine?
I agree with you about power. I've mentioned that a few times. I really like the lower power of the Lynnfield. It's a big advantage. I also would rather use an Athlon based machine for a daily machine, especially with the IGP. I've stated all this. But, for my compiles, I'd rather have an overclocked 920 than a brain-damaged Lynnfield. The same for games.
I'm not too crazy about Anand's benchmarks with the uncore of the Bloomfield running faster. Did you see how there were real differences in the results? 3.5% is not a little when you've only changed the CPU. Part of that is because of the uncore, so it's not really fair to the Lynnfield. I'm glad to finally see you guys showing a difference, but, really, it would have been better with uncore at the same rate.
The memory, it would appear, he's using for the Bloomfield is 1066, that's inferior to 1333.
I would be curious about your video claims. They might be right, but what would be really interesting to try to identical cards, except for memory. My guess is, the inferior setup of the Lynnfield would manifest itself more with smaller memory cards, since you'd have to use PCIe more. I could be wrong, of course, it's just theory, but it would be interesting.
Maybe you guys should stop trying to twist benchmarks to make your point, and just run them to give information. That's the crux of my irritation. The Lynnfield is a good product for a lot of people, and I really like what AMD just did. But, when you do little horsecrap things to manipulate results to illustrate your opinion, that's just wrong. You're not nearly smart enough to think for everyone else; no one person is.

"Gary, Would you care to prove any of this?"Considering most of it is in the existing reviews, how about you go back and read them for yourself? And then take his word for it. Or don't, it's your choice, and your loss if you don't.

You can take this as an offense, you are the idiot here. Always been, always will be.C'DaleRider - Saturday, September 19, 2009 - link
No offense, but you're clearly an idiot. And that is clearly demonstrated by this comment, "Anand uses inferior memory for the i7 920, to try to 'prove' the validity of the brain-damaged P55 platform."What was inferior about the Patriot Viper memory? Care to explain why? I personally think you can't defend that comment on any front, esp. considering it has been shown in testing to be an excellent overclocking selection for DDR3 memory, esp. for the price. It'll do 1600 speeds, albeit with using a CAS 8 setting, but for what it costs, it's excellent stuff.
Grow up, and when you finally move out of your parent's house, maybe you'll be mature enough to lose the teenage "I know-it-all" attitude you possess right now.
