Asus P5N-VM WS - Asus P5N-VM WS
One area of the board that causes concern is the ATX 12V connector which is sandwiched between the heatsink on the power regulation hardware and the back of the I/O panel. It's a four pin connector and there is no space for an eight pin block so you'd better make sure that your power supply has the right type of connector.
Of course, what this board is really all about is the Quadro FX 470 graphics. Is comprises 16 Stream Processors that run at 1,400MHz while the core skips along at 580MHz. Up to 256MB of system memory can be dedicated to the graphics and a 128-bit controller keeps communications ticking over. The graphics core supports OpenGL 2.1, Shader Model 4.0 and DirectX 10.0, which may all seem rather familiar as the spec is exactly the same as the graphics in the GeForce 9400M that are part of the Gigabyte GA-E7AUM-DS2H.
Asus has chosen to install dual DVI-I connectors which strikes us as a thoroughly good idea as workstations are more likely to require two basic digital connections rather than exotic combinations of VGA, HDMI, or Display Port.
It seems likely to us that the Quadro FX 470 is based on the same silicon as the 9400M, just with different drivers. The latest desktop and IGP graphics are on revision 180.48 but Quadro is lagging slightly at version 178.46 for the WHQL driver. There are no Beta drivers listed for Quadro FX 470 as we're talking about serious workstation hardware rather than frivolous gaming so version 180 seems to be a distance away.
Nvidia lists five variants on the theme for Quadro in the shape of Quadro Graphics Driver, Quadro Performance Driver, Quadro Partner Certified Driver, AutoCAD Performance Driver and 3ds Max Performance Driver.
We asked Nvidia which driver was which and were told:
The Quadro Graphics Driver is the one you usually want. The Performance Driver contains both the AutoCAD and 3ds Max optimizations. The partner certified driver adds peace of mind for anyone buying partner certified apps (like many by Autodesk).
The AutoCAD and 3ds Max performance drivers simply only add the enhancements for those products for people that exclusively use them. The idea is the less .dll files you have on the system the more robust it will be.
The problem is that we don't have a reliable benchmark for workstation graphics so all we can say for the time being is that 3DMark06 shows GeForce 9400M in the same light as Quadro FX 470 while PCMark05 discriminated against Quadro.
The spec of the integrated Quadro FX 470 graphics is exactly the same as the discrete FX 570 which as we mentioned sells for £119 so the £64 premium that you pay for the Asus P5N-VM WS over the Gigabyte GA-E7AUM-DS2H looks like remarkably good value. In fact we feel it shows that Quadro carries a colossal premium over GeForce as the next step up the Quadro food chain to the Quadro FX 1700 with 32 Shaders raises the price to £340. That's the equivalent of a GeForce 9500 GT which typically sells for £60 so the concept of value for money seems like a flexible concept in the world of workstations.
Asus has broken new ground by bringing the first motherboard to market that uses nVidia's integrated workstation graphics solution, Quadro FX 470. The performance of the chip may not be stellar but the board layout is sensible - with corners being cut only in the right places - and the price is surprisingly reasonable considering the normal premium Quadro products demand.
