In terms of memory chips cooling, there is nothing new actually. The heatsink taking heat off the memory chips on the front side of the PCB got shaped a little bit differently, although the heatsink on the reverse side of it remained absolutely unchanged.

NVIDIA GeForce FX 5950 Ultra, like GeForce FX 5900 Ultra also features DVI-I, D-Sub and TV-Out ports, and also occupies two slots and requires additional power supply:

The graphics card is based on NVIDIA GeForce FX 5950 Ultra (NV38) working at 475MHz in 3D mode. Unfortunately, I cannot offer you and chip close-ups this time, because the heatsink is so firmly stuck on the thermal pad that I was concerned I could damage the chip when trying to remove it:

The card is equipped with 256MB of DDR graphics memory. These are the Hynix chips with 2.0ns cycle time:

The memory works at 950MHz frequency.

So, NVIDIA GeForce FX 5950 Ultra is none other but an overclocked version of NVIDIA GeForce FX 5900 Ultra and since the heat dissipation grew up as a result of that, the card definitely acquired a more efficient cooling system.

The new graphics card will hardly perform that much faster than the previous GeForce FX 5900 Ultra, because the GPU and memory frequencies in 3D mode have been increased only by 5.6% and 11.8% respectively.

However, NVIDIA has one more weapon ready to help NVIDIA strengthen its positions even more: the new optimizing shader compiler.
