We had a significant amount of requests for Flight Simulator X results in our Core i5/i7 and P55 coverage. I was able to run some quick comparison results between the Bloomfield and Lynnfield platforms last night to answer most of the email and comments requests. However, I am still running the Phenom II and Core 2 Quad benches. I do not know if we will be able to have those results in our P55 roundups that start in a couple of days. If not, I will follow up with these particular performance updates in another blog.

Test Setup-



We are utilizing our standard P55/X58 setups for this test. The 920/860/870 platforms are using 7-7-7-20 1T DDR3-1600 memory configurations. The 750 platform is running at DDR3-1333 with 6-6-6-18 1T timings since the 12x multiplier is not available on the i5/750. The X58 platform is equipped with 6GB of memory and the P55 with 8GB. Turbo mode and Hyper-Threading is enabled as designed and shipped from Intel. All other BIOS settings are at stock ratios.



We enabled DX10, AA/AF, set the Aircraft, Scenery, Weather, and Traffic sliders to Ultra High, and then measured a pre-recorded six minute flight around Honolulu with FRAPS at 1920x1080. Our variability with this benchmark averages around 0.5%. The benchmark is run five times with the median score reported for our results. FSX responds well to both increases in GPU and CPU improvements, but especially differences in CPU clock speeds.


Gaming Performance - Flight Simulator X

When overclocked to 4.2GHz, the 920 and 860 are basically even in this title. The big differences though are the improvements in frame rates, especially the minimum frame rate with a 36% increase compared to the stock 860/870 results. The average frame rates increase 14~21% over the 860/870 stock results.

Due to very aggressive turbo modes, the 860/870 offer the best performance at stock clock settings. No real surprise there, but the improved turbo mode on the i5/750 does allow it to stay even with the i7/920 in this title. All of the processors offered a very enjoyable gaming experience as minimum frame rates were excellent, especially when the processors were overclocked. For those originally wondering, the i5/750-P55 combination will not have any problems running this title at 1920x1080 resolutions with Ultra High quality settings.

OCZ Technology

OCZ recently sent us their upcoming DDR3-2400 C9 4GB Blade series kit. The official specifications call for 9-10-9-24 1T timings at 1.65V VDimm on the P55 platform. We tossed it in our Gigabyte GA-P55M-UD2 motherboard with an i7-870 overclocked to 4.2GHz (21x200), set the memory multiplier to 12x for 2400MHz on the memory, and manually set timings to 9-10-9-24 1T, VDimm to 1.65V, VCore to 1.375V, and VTT to 1.370V.





The OCZ DDR3-2400 Blade kit worked perfectly at its rated specifications on one of the least expensive P55 boards you can purchase. We will have further results shortly.

TankGuys

I normally do not do this, but we were needing a couple i7/860 processors plus a few additional Intel G2 80GB SSD drives quickly for the 860 review and for the expanded motherboard test suite. Normally, we would go to the larger e-tailers like Newegg or others for these items. Well, I was not satisfied with the pricing or availability on either item, so I hit up Ben at TankGuys to see what he could do for us.

Let's just that TankGuys came through with flying colors. Not only did they ship the items before Newegg had them in stock, but their prices were extremely competitive. We spent $269.99 for our i7/860 compared to $299.99 ($289.99 today) at Newegg. Also,the Intel X25-M G2 80GB SSD was $349.99 at Newegg ($309.99 today) compared to $269.99 at TankGuys when we placed our orders. So, it does pay to shop around and sometimes the smaller guys might just be able to offer better prices than the large resellers.

    Any insight on why the Intel G2 SSDs are markup'd up so much? Since the firmware bug has been fixed is something else holding up shipments?
  • TankGuys - Wednesday, September 23, 2009 - link

    Low supply. An OEM or two for the parts can't quite keep up with demand, so there are far fewer drives than people wanting to buy them. Good old economics - supply vs demand ;)

    Does FSX still do all the physics calculations when you benchmark with a pre-recorded flight or is it more like a timedemo?

    Thanks for the update btw, keep them coming! :)
  • Gary Key - Wednesday, September 23, 2009 - link

    Yes, all physic calculations are still performed by the benchmark. It took some time to get there, but it works. :)

    Also, the RAM on the i5 750 was running at DDR3 1333, or is there a way to enable the 12x memory multiplier on the i5 750?
  • Gary Key - Wednesday, September 23, 2009 - link

    In the early BIOS releases, some of the boards had the 12x multi for the 750. It was never stable and was pulled before the boards hit retail. That said, the BIOS guys are still working on it. ;)
  • TA152H - Tuesday, September 22, 2009 - link

    Why didn't you publish the uncore, etc... data for the 860 and 920? Why just the 870?

    Really strange choice.
  • Gary Key - Wednesday, September 23, 2009 - link

    The uncore rates are at stock ratios for each processor as set by Intel.
  • ilnot1 - Wednesday, September 23, 2009 - link

    TA152H if you would just read the article...

    He didn't publish the the uncore's for any of the FSX systems because he stated that all settings were left at their stock/factory/out-of-the-box settings. Except of course for the 860 and 920 that were overclocked to 4.2 GHz.

    The only reason he published the uncore of the 870 (later in the article) is because he was making a special point in showing off the new RAM kit.

    P.S. To Whom It May Concern: Please stop whining about the where the P55 reviews are. They'll be out when they're done. Isn't that why you read the articles on this site because they are well thought out and exhaustively thorough. Well it takes time to get that quality and do things right. The good folks at AnandTech are obviously not slaking off, so just relax. //powering down from rant//

    I have to agree. I really want to see the P55 reviews, but what good are those reviews really going to be unless they are done thoroughly and correctly? They'll post it when its done and there's no reason for them to be slacking.
