Following Sapphire's move to create a Radeon HD 4670 SKU with GDDR4 memory, GeCube has one of its own, ready for launch. The RV730-based graphics card has 512 MB of GDDR4 memory, across a 128-bit wide memory interface. It uses a simplistic design for its PCB and cooler. The card draws all its power from the PCI-Express slot.

The clock speeds on this card differ from the reference ATI specifications. The core is clocked at 750 MHz, with the GDDR4 memory at 2200 MHz. With the memory speed on offer not much higher than what GDDR3 offers, the inclusion of GDDR4 looks more like a dressing to the SKU. It remains to be seen if the memory benefits from overclocking, to overcome the bottlenecks of the narrow memory bus. Rest of its specifications are standard: 320 stream processors, DirectX 10.1 compliance, and support for ATI CrossFireX technology. It is yet to be priced.
