The X1600 PRO if you do not already know, run off the RV530Pro Graphics Processing Unit (GPU). This GPU is based upon the 90 nm production process, which is the norm for majority of today’s GPUs. With such a specification, high clockspeeds are ensured. No doubt the fillrate for this generation of GPU has levelled-up by a notch.

A Red Ruby turned into a Blue Sapphire?

A look at the RV530Pro GPU. Notice the small GPU die. The PCB used by Sapphire has included both 4 hole universal mounting as well as ATi’s two-hole mount.

Zooming in, we find our GPU produced on the 50th week of 2005.

Let’s take a look at the cooling solution offered.

A 60 mm fan and with a extruded aluminium heatsink creates a quiet-running cooling device. We could only detect a tiny whoosh of turbulence under 3D load, else the heatsink fan keeps itself acoutically invisible. Thermal pads transfer heat from the gDDR2 modules to be spread by alumnium heatsink base.

The heatsink has been mounted with silverish thermal paste. It may look like Arctic Silver at certain angles, but the viscousity is sure different.

The supplied drivers CD-ROM and the Users’ Manual.

A wide range of converters and breakouts are supplied. Fret not about the Sapphire being tied solely to your PC. You can use it for Home Theatre too.

The memory voltage regulation module… …

… …and the GPU voltage regulation module.

Nichicon capacitors and encapsulated inductors are used for Pulse Width Modulation ripple filtering. Extensive use of Surface-Mount ceramic capacitors kick out high frequency nasties in the environment, ensuring stability.

8 pieces of 2.5 ns Hynix gDDR2 memory modules grace the GPU for a total of 256MB Video RAM.
