Intel has done it now. Before the Penryn aka Yorkfield chips have even hit the streets they've gone and released yet another chip for the press to go over. Today we take a look at Intel's new poster child, the QX9770 Core 2 Quad Extreme Edition. This newborn Yorkfiled chip features a blistering 1600MHz FSB as its stock setting and runs at 3.2GHz! cheers



Yes kids, that means that those of you that don't like to overclock your precious processors can now buy an extreme edition quad core Penryn QX9770 and feel safe in the knowledge that you pop it into a motherboard - that officially or unofficially supports a 1600MHz FSB - and you can enjoy the power for four cores at 3.2GHz without fiddling!



Above you see proof... CPU-Z showing you that this QX9770 is running at 8x400 MHz, and the multiplier field shows you that the default multiplier is eight. What CPU-Z does not show you is that this processor is also unlocked upwards - it supports multipliers up to 31 as a matter of fact!

Since this is our second Penryn article, we are not going to go over the changes to the Core 2 microarchitecture - for more on Penryn, take a peek at our Penryn QX9650 Launch article.

Why FSB matters

For years now, Intel has been having scaling issues due to still being based on a front side bus. This was exacerbated by the FSB officially being limited to 1066MHz until relatively recently; however when Intel decided to take the breaks off, they did it in style... going to 1333MHz FSB with the P35 chipset, and shortly thereafter, to 1600MHz FSB with the X38 (at least semi-officially, for "official stamp of approval we get the x48 soon). Now Penryn arrives first in 1333FSB (as in the QX9650 Extreme Edition) and today at 1600MHz FSB (QX9770 Extreme Edition).

Frankly, I would not be surprised if we saw 2000MHz FSB support before Nehalem and its CSI show up, but that is pure speculation on my part.

(Our P35 Launch and P38 Launch articles have more information on those chipsets)

Fundementally, the FSB limits how fast the processor can read and write data not only from memory, but also from PCIe and other devices. The FSB is also used to keep the processor caches coherent (in sync), and as GTL+ is packet oriented, there is also a certain ammount of overhead.

A good rule of thumb is that the maximum possible read/write bandwidth is approximately 90% of the FSB frequency multiplied by eight - that's why you will not see extremely high read/write bandwidth scores from dual channel memory setups until Intel goes to on-processor memory controllers with Nehalem.

Here is a handy table that will show you the maximum theoretical gigabytes per second transfer over the FSB, along with the practical maximum that might be reached with an incredibly good chipset:

CLOCK FSB THEO MAX
200 800 6.4 5.8
266 1064 8.5 7.7
333 1332 10.7 9.6
400 1600 12.8 11.5

As you can see the QX9770 has around 10% higher gigabytes/second transfer over the QX9650 at stock speeds. You've already seen our overclocked results in the QX9650 launch review, but now let's put the QX9770 through its paces and see how it stacks up.

If you have a weak heart you might want to skip this review, because it features an absolute monster, the stroke-inducing XFX GeForce 9800 GX2. This dual-PCB, dual-GPU behemoth is the second new release from NVIDIA's new ninth generation of video cards, following last month's introduction of the 9600 GT. The 9800 GX2 is unabashedly reaching for the performance crown, and is promised to outperform -- by a large margin -- even the 8800 Ultra. The only video card that might be able to stand up to the terrific tyranny of the 9800 GX2 is ATI's HD3870X2, which came out last month. In the end, which side will be able to say that they make the fastest video card on the planet? The hardcore of the hardcore gamers are very interested in finding this out.

While the 9600GT was a successful product, offering very good value for its power, some would complain that the unveiling of this first card to bear the 9xxx mark on the box could have been more exciting. Perhaps spoiled by the launch of the ground-breaking 8800 GTX, the 9600 GT's launch -- only in comparison -- was a bit lackluster. Their were no significant enhancements or architectural changes to the 9600GT, instead, it just seemed like the next logical step in the optimization of the GPU since the late October's release of the 8800GT. With today's 9800GX2, it is a bit of a similar case, albeit on a different scale: while no ground-breaking changes are being introduced with the 9800GX2, this card nonetheless has the potential to offer extreme levels of performance -- and for many of us, that is exciting enough.

You could consider the 9600GT and 9800GX2 brother cards in name only, as the 9600GT and 9800GX2 are targeted towards much different markets: the 9600GT was made for the gaming masses, while the roughly $600 9800GX2 was made for the gaming maniacs. But I do mean gaming maniacs in the positive sense of the word -- anyone interested in buying a 9800GX2 knows that they have to pay big bucks to get the best, but that the best, is... well, the best.



If you think you can handle it, let's take a gander at this new dual-GPU powerhouse from XFX

The XFX 9800 GX2 (model PV-T98U-ZHF9) reminded me of that space ship from the beginning of the movie Space Balls. It just seems to go on forever. Make no mistake: this is a monster card. Not much else come to mind when I first laid my eyes on the XFX 9800 GX2: I just thought to myself: This is one serious video card. Its big. Its heavy. Handling the card lends you the certitude that as you soon as you plug it into your system you are going to see fireworks go off; the XFX 9800GX2 just somehow communicates the impression that this a top-end card through its lack of flash and raw dimensions.

As mentioned, the 9800 GX2 is dual-PCB, double-width GPU sandwich. As you can see from below, the front and the back of the card look pretty much the same, which is fairly unusual as video cards go. In the middle of the card, a heavy-duty fan and heat sink connects both PCB's together, working to cool both G92-based GPU's.

The 9800 GX2 also has a few LED's inside the plastic shroud, which is a nice touch. There is a set around the power connectors, and a pair towards the end of the card. Besides looking cool, they also help out by communicating any troubles by blinking, or changing color.

Following are some of the XFX 9800 GX2's vital numbers. Keep in mind that while the 9800GX2 has 256 stream processors, a 512 bit memory interface, and a 1GB of GDDR3, it has half of each of these resources on each separate PCB, which limits their performance, in the same manner as it does with the HD3870X2:



This 9800GX2 is also capable of HybridPower, if you have a motherboard that is capable of this feature. HybridPower allows for you to use Windows and other applications using your motherboard's integrated GPU, while keeping the 9800GX2 in a standby mode to only be activated when 3D mode is required. This is nice feature to have for a card of this magnitude, because it does use a significant amount of power.

I'm not sure about you, but I'm quite anxious to see what this 9800 GX2 can do. Let's move along.

Introducing the X48

Today we will take a look at Asus' P5E3 Premium - a feature packed motherboard, based on the Intel X48 chipset.

Don't be surprised If this board seems familiar to you - it is basically a new version of the X38 based Asus P5E3 Deluxe WiFi that we reviewed last October. Visually, the boards look practically identical, with the only difference being this board having three less chassis fan connectors, two less USB ports, and one PCIe x1 slot less than the X38 based board. And other than being labelled with an 'X48' instead of an 'X38', and officially supporting a 1600MHz FSB - and presumably with a newer BIOS revision - I strongly suspect that other than the cost reductions due to the fewer connectors, the boards ARE basically the same.

Frankly, it is widely known on the net that the X48 chipset is basically identical to the X38 chipset, other than officially supporting 1600MHz FSB - at most it seems to be a new die revision of the X38. At most.

Mind you, none of the above really matters - as even the X38 was a fine chip.

Ok, now that we have the obvious out of the way, let's take a look at the specifications of this board.

The Logitech G9 is the latest in the long series of G series devices by the company, in previous entries we had seen the company play with optical versus laser as well as ergonomic and universal hand grip styles, this time around we get multiple grips for play with, MicroGear on the scroll wheel, more / heavier weights in the base and an adjustable range from 200dpi - 3200dpi with no lag.

Let’s go over the specs for a moment.
Performance

* Interchangeable Grips: Use the included Wide Load and Precision grips to get a fit and feel that’s best for your playing style. The satin texture and fuller shape of Wide Load add extra comfort while the DryGrip technology plus compact shape of the Precision grip give you unmatched fingertip control.
* 3200 dpi laser engine with Full-Speed USB: Get uncompromising speed and accuracy from a high-performance Gaming-Grade laser engine—plus instant cursor response with Full-Speed USB (up to 1000 reports/second).
* Game settings to go: Take your personal mouse preferences with you. The G9 saves mouse settings in onboard memory—store up to 5 profiles (including keyboard macros, dpi settings, and LED color) on the mouse and play your way—without additional software installation*—on other PCs.

Control

* MicroGear™ Precision Scroll Wheel: Use Logitech’s exclusive MicroGear™ scrolling technology for precise, click-to-click scrolling—perfect for quick weapon selection. Or switch modes for frictionless, hyper-fast scrolling.
* Adjustable sensitivity: Shift from pixel-precise targeting to lightning-fast maneuvers without pausing the action. The G9 gives you instant access to multiple sensitivity levels between 200 and 3200 dpi, without driver installation.
* Weight tuning system: Prefer a heavier or lighter mouse? Use the weight cartridge and up to 28 grams of metal weights to customize your G9 for just the right feel.
* Polytetrafluoroethylene feet: Super-slick feet glide effortlessly across almost any surface.

Comfort and Convenience

* Custom-color LEDs: A color LED display indicates the current sensitivity level and profile settings. Personalize the color LED display by choosing from hundreds of colors.
* More grip styles: Swap out your grip for a new look and feel. In addition to the provided Wide Load and Precision grips, other grip styles are available for purchase.


Overall the unit is really heavily packed with features from past units; personally it's nice to see MicroGear make it from the MX revolution to this new incarnation.

Let’s go over our field of test mice.

ATI releasing a HD 3830 video card next month

More ammunition to compete with the 9600GT.
ATI releasing a HD 3830 video card next month


Rumors coming from the far, far side of the pond (China) seem to suggest that ATI will be releasing a HD 3830 product next month. The card will be much like a HD 3850 (320 S.P's, 256MB, etcetera) but with a 128-bit memory interface. It will be priced around $119 and $129 dollars. While it seems that it'll have a very hard time competing up against the speedy and cheap 9600GT (often selling for around $149), ATI doesn't really have a good card currently at this price point, so it makes sense that they'd move to fill this gap.

It seems like the card will be a quite similar (or the same as) the HD 3690, which was only released in the East.

From my video card reviewing experience, I don't believe a HD 3850 with a 128-bit memory interface would be able to hold a stick to the 9600 GT's performance, but it is much too early to tell. However, on the other side of things, around that lower price point, $20 dollars can make all the difference.
