Asus V8440 TD and V8460 ultra TD in the test: Two 'Ti' tans among themselves

Asus V8440 TD and V8460 ultra TD in the test: Two 'Ti' tans among themselves

The cards

This brings us to a detailed presentation of the two cards.

What they both have in common is largely the layout, which, except for the cooler, is based on the nVidia reference design. The TV output is provided by a chip from Conexant that is attached to the back. In addition to the normal D-Sub VGA output, there is also a DVI connection and a TV-out. Thanks to the TwinView, which has been improved in the GeForce4 series, now under the name 'nView', two of these outputs can be used virtually independently of one another. Furthermore, there is of course an adequate cooler that distributes not inconsiderable waste heat from the nV25 chip in the case without any unusual noise. On the packaging of at least the V8460, Asus itself speaks of a 'Copper Fan Sink for superior stability and performance'. The weight of this cooler also strongly suggests that it is a much heavier material than aluminum, but the outside is obviously nickel-plated.

After we saw the excessive use of RAM coolers on the last two generations of nVidia cards, one is astonished to find that these RAM chips, which have so far been the fastest clocked in the consumer segment, have completely dispensed with passive cooling. This is mainly thanks to the new packaging in the µBGA, with the help of which the chips can be placed directly on the mainboard and, through a larger number of contacts, can also conduct part of their heat directly into the PCB, the board itself. Nonetheless, some of these got more than lukewarm in test mode under full load, which did not result in any instabilities (even in overclocked operation).

In detail, first the 'smaller' model, the Asus V8440:

According to the nVidia specification, the chip is clocked with 275MHz and the RAM is also addressed with 275MHz, which achieves a transfer rate of 550MHz thanks to the double data rate technology. 4 chips in the modern µBGA format are soldered onto the front and back, which together provide a total size of 128MB. These are Samsung chips with an access time of 3.6ns which are operated with the 275MHz on the edge of their specification.

Asus V8460 Ultra

And here now the top model, the Asus V8460 Ultra:

First a word about the timing: Contrary to some Rumors in advance will at least the current revision of the V8460 with the reference clocks of 300MHz for the chip and 325MHz for the RAM, whereby the latter still has a lot of room for improvement due to its specified access time of record-breaking 2.8ns n has. From a purely mathematical point of view, it should be possible to run it at 357MHz.

Of course, 128MB of graphics ram are also at the start here, as well as inµBGA version as with the smaller brother. The only differences between the cards are in the RAM used, the chip and the color of the board.
