Gaming Performance: UT3 and COH

UnrealTournament 3 'Coret Fly-By' - Low Resolution

UnrealTournament 3 'Coret Fly-By' - High Resolution

We were actually able to measure a slight performance advantage for P45 when benching Unreal Tournament 3 (UT3). Our best results with this game have always come from Intel-based boards, as UT3 is extremely responsive to low memory latencies when tuned properly. Without a doubt, for those that plan on purchasing no more than one video card for the purposes of playing UT3, this is a great board. Of course, the results become somewhat muddled at higher resolutions due to GPU limitations with each board performing similarly at 1920x1200 pixels. At this point, only another GPU can provide relief and higher frame rates.

Companyof Heroes: Opposing Fronts - Low Resolution

Performance of COH: Opposing Fronts at low resolutions has a lot to do with raw CPU muscle, which is why each setup performs nearly the same. At these frame rates, everything is smooth as silk. Enabling AA is good way to improve the image quality when dealing with such a surplus of power.

Companyof Heroes: Opposing Fronts - High Resolution

Even at the higher resolution (1920x1200) Company of Heroes is still entirely playable with just a single 8800 GTS 512MB (G92) GPU. SLI scaling with this game is nearly perfect; adding a second GPU nearly doubled our measured average frame rate from around 110FPS to nearly 210FPS with a 45nm quad-core CPU.

    is this true?

    so it mean i will no need to buy ASUS x48 MB?

    $250 is way too much, especially for a low end chipset board. I just bought a board for $60 that does 100% of what I need for a new Vista-64 machine with Crossfire. The MB pricing has been going through the roof lately.

    We've just received an MSRP update direct from ASUS, expect to see this board selling for about $229 with the P5Q (DDR2) variant available for about $209.

    the instant on technology Asus put on this thing?
    Some stripped down linux distro as I understand it

    After looking things over with the P35 added to the mix, I'm going to be completely honest here -- the P45 at any substantial premium is a load of crap.

    By my calculations, the performance difference between a P35 and P45 is 2-3% at most, and the majority of the time you're only talking about tenths of a percent.

    When you consider that P35 boards are selling for as low as $75 now (with several from Asus going for under $100), you'd have to be nuts to pay $225+ for a difference which is hardly even worth mentioning.


    Sure, you can save anywhere from 7-19 watts with the P45 (depending on the application), but you can save twice that by replacing one of your light bulbs with a compact florescent. Spend your money elsewhere.

    "two RJ-45 1000GBps Ethernet ports"

    Oh my god! I must go out and buy a hundred of these, make a super switch out of them! That's incredible, are they going to do away with SATA now that Asus made Ethernet run 300x faster?

    Well, actually I wish ASUS (and other board makers) made their board with ONE Intel Gigabit PHY, instead of two or four Marvell PHY. Heck, get rid of that EPU BS while you're at it.

    I want to get excited. I really do. But as an owner of a Gigabyte P965 DS3 I just can't get aroused. My e4300 still is clocking strong at 3.0ghz. There isn't enough speed to justify going .45nm just to hit 3.8 - 4.0ghz and also having to go to DDR3. Even if they release a DDR2 board its likely is it going to be worth buying a new board or just installing a 'beta' bios on my current setup if I did want to get a .45nm chip.

    Just seems Intel wants to go out with a bang and also have more unload options for their C2Ds when they switch platforms within the next year.

    If I was buying new, I'd be really tempted but good ol' faithful P965 is running 1 year strong on a mild OC 'according to today's standards of OCing.'

    [quote]The P5Q3 may report the use of a 16-phase PWM but we know better. [/quote]

    Do we, really?

    [quote]Although ASUS design engineers have added a lot of extra chokes and MOSFETS, the overall capacity of the power delivery circuit remains comparable to their competitors' more modest 8-phase designs.[/quote]

    From the review we don't know what components Asus used in its PWM design (MOSFETs, drivers etc) - heck, we don't even know what PWM controller they have there. It could be the same ADP3198 4-phase controller Asus had been using for some time, or it could be a newer, improved one - especially considering that Analog transferred much of its CPU PWM controller range to ON Semiconductor late last year.

    We don't have figures from Asus engineers. We also did not examine the circuitry's layout, overally efficiency, transient response, peak and sustained load-handling capabilities ... nothing of the sort, yet we're prepared to come to a positive conclusion regarding the capabilities and quality of the circuitry, and indeed compare it with others. An educated guess, based on some evidence to back it up, would've probably been more appropriate. IMHO it's not exactly fair (or professional) to jump to such a conclusion with merely an assertion without any substantiation to support it. That's expected from readers who can only look at the product and play the armchair general, but not from reviewers who actually have the product and can (and should) do what they can to properly assess it for the benefit of said readers.

    As for the rest of the review, it was certainly interesting; however correct me if I'm wrong, but it seems that ICH10/R is supposed to bring rather more to the table than just 2 more SATA ports plus AHCI capabilities for the non-R version. For instance, apparently a 10GbE MAC is integrated as well.

    However, as with the ICH9's integrated GbE MAC, many manufacturers may balk at having to use specific (particularly, i8256x) Intel PHYs in order to make use of that MAC, since it requires a PHY that supports Intel's GLCI/LCI bus. Instead, manufacturers may choose to provide the usual PCIe/PCI controllers that they've normally been using, to keep inventory and costs under control (such controllers can be used on AMD platform products, for example). Perhaps the same proprietary-PHY issues might plague implementation of ICH10's rumoured Wi-Fi capabilities as well... all in all, then, it does seem that as far as the end user of actual motherboard products is concerned, there would apparently be very little that's new with the ICH10. IMHO, Intel could've added more PCIe lanes, which would probably have been better appreciated.

    Speaking of PCIe lanes, that's probably one reason Asus chose to stick with USB for the wireless module. USB does the job well enough - if it ain't broken, why fix it? PCIe x1 is overkill and ICH10 is already in dire shortage of lanes, with 1 going to network (2 for dual-NIC motherboards), 1 or 2 going to PCIe x1 slots and just 4 left to go to the third graphics card x16 slot. With the abundance of USB ports that ICH9 and 10 provide, Asus probably figured that using one for the wireless module can't hurt. And if anything it's probably to do with inventory and ease of design as well, since Asus does make wireless USB adapters - you could use the same basic circuit design and fit it with a motherboard USB connector and external antenna interface - voila, wireless for motherboards.

    At least Anandtech did not help perpetuate the unconfirmed (and unlikely) rumour that ICH10 eliminates legacy ports like PS/2, parallel, serial, game/MIDI and so on - since those ports have little to do with the south bridge at all. These legacy ports connect to Super I/O chips, which on modern motherboards is also the H/W monitoring IC, and which in turn connect to the south bridge via the LPC interface. Thus the only way an ICH could completely remove support for legacy ports in current motherboard architectures would be to remove the LPC bus - which would also remove H/W monitoring as well as BIOS, unless it's part of Intel's force-forward plan to move to SPI for BIOS, a la RDRAM and PATA. That still leaves H/W monitoring high and dry though.

    On another note, as others here (especially Frumious1) have commented, it would be good to compared Intel chipsets from, say, P965 through P45 to see what improvements P45 brings. Perhaps some useful metrics would be performance tests for memory (read/write/copy/latency/overclockability), CrossFire (x8,x8 on P45 vs x8,x8 using a PCIe switch IC vs 16,x4 etc), disk and USB subsystems (read/write/copy/copy across ports), power consumption. Oh and please have all the tested boards participate in all tests, so that there's a complete comparison across the board.

    Admittedly, power consumption is the trickiest of them all because each generation of motherboards have different components and/or different features (e.g. one has FireWire while another doesn't, or one uses a FireWire controller from Agere while another uses one from VIA etc). Perhaps we could try disabling all such external controllers in BIOS and seeing if that makes a difference to power consumption (ie whether the option turns the controllers off or merely disconnects them) then, if turning them off does work, test the boards with all external options disabled. That, at least, minimises variables to board layout and CPU/MCH/ICH/RAM power circuitry subsystems - which would be useful metrics themselves. Just a suggestion!
