The card itself is one of the biggest I have seen for an AGP desktop card. Resembling in size to that of the old Voodoo 2 PCI, ASUS has left plenty of room to allow for the required capacitors and allowed extra room for cooling purposes. Designed around the NVIDIA reference size boards, ASUS are normally one of the few that deviate from NVIDIA's specifications to make their cards unique, this time, better safe than sorry considering how sensitive these clock speeds can be.
Cooling the super GPU
ASUS have used a new heatsink on the GeForce 4 TI4600 beast. The 4600 GPU is essentially a super clocked GeForce 4 CPU and therefore produces a massive amount of heat. NVIDIA have released new specs for cooling applications and ASUS have adapted their cooling around this new spec. Unlike GeForce 3 Ti cards, the GPU only requires cooling when using this new configuration, this is a good advance as adding the extra heatsinks to the memory ends up costing the consumer extra money for the extra cooling which has had to be added to the video card.
You can see that this video card is using the very early revisions of the GeForce 4 Ti core, as it hasn't even been named the GeForce 4 yet but referred to as the NV25, its code name. This will change however for retail samples since NVIDIA has had time to change the metal slug over with the new Ti logo.
Memory - Super fast!
The ASUS card requires no cooling on the memory chips and this is why. The card is packaged with 8x32MB MicroBGA memory chips from Samsung running at 3ns. This allows for the memory to run much faster, much cooler and allow for higher clock speeds for future uses. Overclockers rejoice!
It just wouldn't be an ASUS video card without TV capabilities and so it is with the Ti4600. This early sample is equipped with the Conexant TV Encoder chip for fair TV quality, moving to Phillips would see TV quality improve but we won't know this until retail samples make their way to us.
The Back of the beast
ASUS has elected not to place all of the memory chips on the top side of the video card. MicroBGA allows for four of the memory chips to be placed on the back of the video card, as the NVIDIA specs state, guess ASUS are trying for the stability factor in the early samples.
