Surprise, surprise – here is NVIDIA's upcoming GeForce 7900GT. NVIDIA’s newest GPU, dubbed G71, will debut at CeBit 2006 in Hannover in a few weeks.
NVIDIA's new 7900GT is expected to use new
Samsung GDDR3 memory that's reported to be operating at 1.4ns but
frequencies are unconfirmed at this point. In contrast, ATI's X1800XT
uses GDDR3 memory with a 1.2ns time running at 1400MHz. NVIDIA's
7800GTX 512 uses memory running at an effective rate of 1.7GHz.
We have a few images of the 7900GT from NVIDIA (right). The
7900GT will feature a single slot cooling
design, although the cooler demonstrated in the images we captured is
stock cooler that will appear on the final design. An interesting
engineering element on the reference board includes a set of 4-pin leads for
what we are told is for an audio jack -- or at least the leads for an audio
jack. If it is indeed an input for audio signals (appears to be SPDIF),
then for upcoming graphics cards that boast HDMI connectivity, this
would definitely make sense. As for the current reference design, there
is no such connector featured and we will have to wait for final
designs to see what happens.
NVIDIA roadmaps have confirmed to us that the
90nm 7900GT will feature 24 pipelines with a 450MHz core clock. Like the
GeForce 7800GTX series, the 7900GT comes with this warning:
Note: For two GeForce 7900 GT-based graphics
cards running in NVIDIA SLI configurations, a minimum 450W system power
supply (with 12V rating of 26A) is recommended.
