avatar ASUS EN7800GT DUAL 2/2000 Edition Review

In order to get a system to run in SLi mode, you would usually have to buy 2 graphics card of the same model. But today, VR-Zone takes a look at this physically large graphics card, that actually has 2 7800GT cores on a single PCB, connected via NVIDIA’s SLi interface. Look here for performance benchmarks and more pictures on this monster card!

NVIDIA’s concept of SLi is tobring 2 or more graphics cards to work in
parallelism with the help of their proprietary interface and drivers. With the
introduction of SLi based solution sometime last year together with the GeForce
6 series of graphics cards, NVIDIA has pushed the performance bar to a level
above all competitors in the gaming scene. Through this level of
parallelism, it wasn’t long before we see some very interesting solutions from
graphic card makers…

Following closely the theory of “2 are always better then 1″, ASUS first
shocked the world with its introduction of both the EN6800Ultra-DUAL, and the
EN6800GT-DUAL. Being more of a prototype board then anything close to
retail, it never took off really simply due to its price and also partially due to
its insane physical size of the board. Gigabyte on the other hand, managed to
push some of their “dual-GPU-on-single-card” solutions (Gigabyte 3D1)
into the retail channel.

This time, ASUS has ironed out some of the issues with from the older
EN6800Ultra-DUAL and introduced the EN7800GT-DUAL. With 2 major issues ironed
out, this new EN7800GT-DUAL wull finally be a retail product. Now with a
smaller PCB board, it can be more readily accepted by retail channels. Also,
with its own dedicated power brick, no more power related problems will
actually arise. To add on, this EN7800GT-DUAL can actually work on any SLi
motherboard, not just limited to ASUS boards only. It’ll be interesting to see
NForce 4 Ultra motherboards (Ultra and not SLI) run a card like this.

Before we start, some might ask, why do we need 2 cores on a single PCB card,
when 2 individual graphics card in SLi mode can do the same? Having a single
PCB card that features 2 cores; it brings up a whole new level of parallelism.
With recent developments already ongoing at ASUS’s labs, it’s just a matter of
time before we start to see 2 of such dual GPU cards running on one motherboard(4 effective
GPU).

The packaging of this EN7800GT-DUAL. With this trademark
massive box similarly sized as the 7800GTX TOP and the 6600GT Silencer, it
appears that ASUS wants to make their graphics products as prominent as possible
on the retail shelves.
