Cinema 4D R11 x64

Cinema 4D R11 is one of our favorite programs to create high-end 3D images and animations. This particular program is sensitive to memory bandwidth and is well threaded. We track the time it takes to render a swimming pool layout.

Our i7/920 finishes first with the i7/860 just a second behind at 3.8GHz and with HT enabled. Disabling HT decreases performance 15% when these two CPUs are overclocked. The 965 BE is 27% slower at 3.8GHz than the i7/920 with HT enabled and 14% with HT disabled.

Turbo mode benefits the i5/750 greatly in this benchmark as turning it off results in the 750 being 16% slower. However, pure CPU speed allows the 965 BE to finish the benchmark about 10% quicker than the 750 with Turbo enabled and 23% with Turbo disabled with a 28% higher base clock speed. Of course, the 965 BE is 17% more expensive based on CPU cost comparisons.

LightWave 3D 9.6 x64

Another popular 3D rendering program is Lightwave 3D 9.6. In this test we time the rendering of a single frame from an office building animation. The time to render the full scene is approximately four and a half hours. This title is also well threaded and sensitive to both memory bandwidth and latency.

Lightwave also favors HT enabled processors with the 860/920 tying for first at 3.8GHz. Interestingly enough, Turbo mode on the i5/750 only offered a 3% improvement in this bench. The 965 BE scales very well as a 11% core speed increase nets a 10% improvement in the benchmark. However, the 965 BE still trails the 860/920 CPUs by 26% at 3.8GHz.

MainConcept Reference 1.61

One of our favorite video transcoding utilities is MainConcept Reference. We set our profile to iPOD HQ NTSC and then transcode a 651MB 1080P file to an iPOD HQ 34.7MB file.

HyperThreading does not make a difference in this title with the 860/920 finishing in a dead heat again. Turbo mode for the i5/750 improves its scores by 11%. Once again, the 965 BE scales very well with an 11% increase in speed resulting in a 9% benchmark improvement. Otherwise, the 965 BE trails the 860/920/750 by 29% at 3.8GHz.

Sonar Producer 8 x64

We utilize Sonar Producer extensively at home when mixing various music tracks. This test performs a complex mix of five individual tracks into a single title. We covert these tracks into a WAV format utilizing a 192kHz sample rate along with all other options enabled. This title thrives on memory bandwidth.

We finally see some separation between the 860 and 920 processors in this benchmark. Based on offline memory testing, we contribute this to the 920’s slightly better throughput under load conditions. The i5/750 performs 13% better with turbo enabled. The 965 BE performs 15% worse than the 750 at 3.8GHz.

Adobe Lightroom 2.4 x64

Lightroom is a quick and easy to use program for batch conversions on digital photos. We perform a standard conversion of 50 RAW images into the JPEG format.

HyperThreading does not matter in this title. The 920 finishes just slightly ahead of the 860. Turbo mode makes 9% difference for the i5/750, just enough to place ahead of the 965 BE at stock speeds. Once overclocked, the 965 BE is 17% slower than the 750.

CyberLink MediaShow Espresso

We transcode a 370MB 1080AVCHD file into a HD friendly file suitable for publishing on YouTube. This program features GPU hardware accelerated decoding via ATI Stream or NVIDIA CUDA but is disabled in our test routines.

Even with a 740MHz advantage in clock speed, the 965 BE is just equal to the i5/750 with Turbo disabled in this application. Obviously, it appears this particular program behaves differently on Intel processors. Even at a 3.8GHz clock speed, the 965 BE trails the i5/750 by 24%. The 920/860 processors continue to be close, even though in this application the 920 has a slight advantage.

    duh n/m i must have been hoped up on too much coffee... 4x2GB.

    I really need to find 4 sticks of 4GB and the only ones i've found are by Kingston and they want $1,000 for them.

    Any suggestions?

    Hello.

    I'm eagerly awaiting for the finished review. i'm currently upgrading my system, thinking of 920/x58 or 860/p55, been scouring the net for the information that'll affect my decision. i think i'm on the verge of choosing but the thing that 'i think' is missing is

    cpu temp idle/load at OC 3.8;
    power consumption idle/load at OC 3.8;

    if you could include this data i thank you.

    You'd have to be retarded to buy a Lynnfield if you have enough money to get an i7 920 setup.

    This site tries very hard to push the P55, while trying to appear unbiased. Why? Who the Hell knows? Maybe Anand decreed the P55 should be put in a good light. I really don't know, but at this point I'm sure they are being biased, either consciously or unconsciously.

    But, you're really better off with Bloomfield if you can afford it.

    In this article, they make the overclocked processors look similar, but what they don't tell you is they run the memory controller faster on the Lynnfield, as well as the L3 cache. Why don't they tell you? They don't want you to know.

    So, clearly, the Bloomfield is faster even on the benchmarks they selected. I suggest you go to better sites and see the actual benchmarks, where you can see a slight performance increase on virtually any workload when the comparisons are apple to apple.

    You get better expandability, better granularity with uncore clock speeds, and memory (since you can add in multiples of two or three), better performance, and a better upgrade path since you will be able to use multi-GPU cards without penalties, and will be able to upgrade to a 6 core CPU without yanking the motherboard.

    Just make sure you get the D0 stepping of the 920. The C0 is slightly slower, and uses more power.

    If you can't swing the price of the 920, probably the i5 750 is a decent processor. I wouldn't even think about the 860 or 870. They run into Bloomfield territory, and why suffer a brain-damaged platform when you don't need to?

    Curious. I don't see any actual difference between the 920 and the 860. I wouldn't consider anything under 3% to be significant, however.

    You're speculation on the bias of one site or another is just more bias, but on your part. I don't (and I'm pretty sure that you don't) know nor can prove (and neither can you) prove any bias one way or the other. From the benchmarks that I've seen from this site, it's clear to me that the P55 is a strong platform and competes well against the 920.

    Who cares if the memory clock runs faster or slower? How much of a significant difference does it really make to the end user? I suspect that the answer is "No way to be noticeable".

    I doubt that if you're concerned over saving a couple of bucks on the CPU/Mobo, you're not going to see any upgrade path along the X58 as an actual viable alternative. I seriously doubt that the 6 core processors will ever get to a "reasonable" price that will make it worthwhile to upgrade to, particularly if you're thinking about going the 920 route rather than a much more expensive CPU.

    My prediction (and it's just that, a prediction) is that when the 6 core processors are "mainstream" (which Intel hasn't really suggested that they will be in the near future), the "next best thing" (i9? whatever the future Intel line is) will be out, and prices on those will make the 6 core upgrade path not worthwhile. All while using up more power without getting any tangible benefit in the short or long term.

    You can argue that the memory controller is "brain-damaged", but from what I've seen from benchmarks here, there doesn't appear to be any tangible problem with that. Oh, a tangible difference would be in a real world scenario, not any synthetic memory stress test benchmark.

    You're not really comprehending what I'm saying.

    Of course this site won't show any appreciable difference, that's my point! They skew everything so it won't.

    For example, did you know they had to set the 860 to 1.312 volts, while they set the i7 920 to 1.232. Hmmmm, you probably didn't.

    Keep in mind, if you increase the uncore speed for the processor, you not only improve memory performance, but you increase L3 cache performance, which is important.

    I've already given reasons for my comments, so don't say it's just speculation. You think running the uncore slower, without mentioning it, is by accident?

    Look at other sites that really testing, and you see on a lot of benchmarks, the performance spread is different. This site will hide pertinent information, and then show benchmark results, knowing that most of the people won't really look at the details. And then they can say crap like, the difference wasn't really important.

    You really don't think it was worth mentioning they were running the uncore 200 MHz lower? Or the processor required considerably less voltage to reach the same clock speed? This is computers we are talking about, and computers are precise. You can't come to conclusions without precision in how you test, but, strangely, they have become really sloppy, and all in a way that benefits the P55.

    It's really bizarre. Not that I mind it, I'm past being irritated, and now I'm fascinated by just how gullible people are, and how unquestioning. People don't question what they want to see. It's been very educational. The sad part is, the ones who object to results are mostly doing it on partisan grounds (meaning, they are pro-AMD), although it's always refreshing to see others who realize the i7 920 is the best in it's price class, despite the disinformation spread by this site.

    I don't think Intel made a mistake with the brain-damaged Lynnfield, by the way. I think stock, which is how most processors are sold, it's fine. Well, I do think they made a mistake; not adding a IGP with it. I realize it's more difficult with an IMC, but they've had plenty of time to get something out. So, it's really a nothing technology that will fade into obscurity until they come out with an IGP, or get rid of the i7 920. It's brain-damaged, so it's not going to attract the high-end buyer, but it also doesn't have a proper platform to be a true Celeron. So, I think it's going to sell poorly. I don't think they'll be very successful conveying the value of it, although I think the i5 750 is best in class for that market segment.

    I think AMD's new Athlon will sell really well. It's quad core, and cheap, and runs at reasonable clock speeds. If you're the typical buying public, you see quad core, a lot cheaper, with higher clock speeds than the i5 750. The nice thing is, it's actually smaller too, or reusing dead parts that would have to be thrown out. For people that have a clue and want high end, it's the Bloomfield. I just don't see this having a big market near term.

    Intel is a screwy company. They get some things so right, like the Atom, and screw up things like not getting it a good chipset. They come out with the Lynnfields, and don't give it a proper IGP. Most computers DO sell with IGPs. Why leave themselves out of this market with these new products? I just don't understand them.

    No, I do comprehend what you're saying. I believe that what you're saying isn't really all that relevant in the grand scheme of things. I'm just not seeing any tangible results (>3% difference) in actual usage.

    And fundamentally, that's my point. I've been following the computing industry since before Anand had anandtech, and one of the things that I have noticed is that synthetic benchmarks are, for most purposes, worthless. Who cares if CPU A has 30% more memory bandwidth, if the vast majority of tasks show an insignificant increase in performance in a game, or in encoding, or in compiling, general computing, or in some combination of those four?

    The point is that you're complaining about, what I consider to be, more or less trivialities. I say this because based on the numbers of a non-overclocked system, Lynnfield is exceptionally competetive with the 920. Sufficient in my mind to make the 920's really not that relevant. In fact, if you don't overclock, the 920's are actually slower in the setups that I care about (ie more or less everything except some memory benchmarks that don't ultimately mean anything). All that I can say about synthetic benchmarks is that some thing is faster than another. In fact, in those synthetic benchmarks, you can't really make meaningful conclusions as to the degree to which one product is faster than the other in a real-world scenario.

    I used to be like you. I used to put too much stake in a synthetic benchmarks. I used to think that they were important beyond making some generalized comments as to the which product was faster than another product. However, after about 20 years, I finally started to see the light.

    However, I'd like to see where you believe this to be an important distinction. I've looked at a few other sites, and haven't found any tangible differences between the two. I've looked at this site, tomshardware, xbitlabs, and pcper. Where else are you seeing such a marked (and meaningful) difference in performance?

    hello.

    We all are trying to find " tangible differences " between 860 920 p55 x58 750 i5 i7 etc etc..

    i don't think wanting to know the CPU Temperature and CPU Power Consumption at Overclock Speed of 3.8 Ghz is "More or less trivialities". because this is My "real-world scenario"

    i'm deciding which to buy, 860 or 920. these are my deciding factors

    when overclocked to 4 ghz lynnfield temperatures are almost 100C, which is catastrophic.
    and the power consumption skyrockets.

    people is already complaining.

    Cons: 1) Lotsa of voltage increase needed to go past 3.6
    2) no good coolers *yet* (I purchased coolermaster hyper 212 plus, better than stock but....)

    Other Thoughts: Everytime i get a processor from newegg its like i'm destined to get the bottom of the barrel. after seeing initial reviews from various websites i was thinking 4ghz would be easy to obtain. Well i hit 3.6 ghz on stock voltage stable with prime 95, took 1.336 volts to get 3.8 ghz, and finally took me 1.375 volts to get to 4.0 ghz. Could run prime95 stable @ 4.0 ghz temps hitting mid 90's but i guess i'll back off 4.0 ghz til i find out more on this processor. initial reviews stated you wanted to stay under 1.4v, but i'm iffy on that if i want this thing to run for 6 months. kinda wish i woulda opted for the i920, i recommend anyone does if that can get a d0 stepping.

    For all your complaints about them hiding information and such, do you actually have any references to prove that there is more than a few % difference in multiple real-world applications between the 860 and 920 when everything is set as equally as you want? From the memory scaling articles I have seen you need large changes in bandwidth or latency to get noticeable improvements in real applications.

    The difference in voltage needed to OC is of much more interest to me. Gary mentions that the 860 might save a lot of power, which seems counterintuitive to needing more voltage. The 750 is meaningless to me, I can afford either the 860 920 platforms, and have no use for better SLI/CF performance, so if performance is equal than other factors like power/temps and stability will make my decision. Al else equal, I'll take the 920 on the extremely slim chance a Gulftown will actually be cheap enough to buy. If the 860 really does draw only ~2/3 the power, I'd go with that.
