Asus X1950 Pro Crossfire (EAX1950PRO)

A closer Look - Asus EAX1950PRO

The Card

Asus has implemented their own cooler on their X1950 Pro. With a sleek white design topped with a nice looking mesh on top Asus have done a good job in the design stakes. The heatpipe peering out of the top of the cooler gives this reviewer some confidence in Asus' cooling solution: heatpipe's are a good thing as far as graphics cards are concerned.

The rear of the card looks fairly familiar; although notice the slightly different location of the power circuitry for the moved PCI-e power connector. You can also see the dual-link crossfire gold-plated connections on the top of the PCB very similar to nVidia's implementation.

The power connector is in the middle of the board on the Asus cards. This doesn't present any cable tidying issues although it's very marginally harder to get to if you have a case loaded up with as many goodies as mine is.

Here we can see the heatpipe in all it's glory. Asus have chosen to go with an aluminium heatsink with a copper contact area. This keeps the card fairly cool under load as you will see below.

You have to be aware that this does stick up slightly (1.5-2cm) from the top of the card so people with very small cases should be aware.

The Asus X1950 Pro features Dual DVI connectors and the card also has HDCP implemented as standard. This is excellent news for those wishing to purchase this for the future as Vista will eventually require a card with HDCP coded into it.

An S-Video connector is included so you can plug the card straight into your hi-def TV.

The card features Samsung's K4J55323QG GDDR3 modules rated at 1.4ns and Asus have chosen to clock this at 700MHz (1400), which is exactly what this translates to.


As stated previously, Asus have implemented their own cooling on the card. The cooler features a fairly compact fan that draws air over some fins connected to the heatpipe. Heatpipes are very efficient at drawing heat away from area's that need to be cool and so it's good to see Asus implementing this.

The downsize of this cooler is that it does suffer from a whooshing sound when it's under full load and if you have a particularly quiet system you may notice a slight whirring at idle. This is not to say it is a loud cooler, but if you are a totally silent PC user then this card will get mildly annoying.

One thing that I was slightly disappointed at was the fact that the cooler takes up two slots. This meant I had to move my X-Fi down to the lowest PCI port when I ran two of the X1950 Pro's in Crossfire mode. I think that Asus could have implemented a single-slot cooler on this card, considering the stock ATI reference board uses a single slot cooler. This is only a minor point if you are not going for the fully fledged Crossfire.

I loaded up Rivatuner to check the temperature of the cards in Crossfire and this stayed at a very nice and cool 41°C at idle and 57°C load (ambient 23°C).

All in all it's a nice solution from Asus and certainly would make your case look pretty neat with it's understated looks and aggressive heatpipe.

Definitely too late, unless you're on a tight budget. With the onslaught of nVidia's DX10 8800GTX's and GTS's, I don't see them selling very well, especially when nVidia starts slinging mid-range DX10 GT's into the market. (Is the 'GTS' supposed to be the 'GT' version? I'm a bit confused right now.)

No I have to say £133 for a GPU that performs that well is an absolute bargain. no diggedy no doubtQuote
