Radeon HD 4730 from Powercolor officially introduced
Powercolor just announced a Radeon HD 4730 graphics card. The product of the PCS series offers more than 640 Shader ALUs and 900 MHz GDDR5 video memory.
The Powercolor HD 4730 PCS is said to become available on June 8 for 79.99 USD. The frequency of the yet unspecified GPU is set to 700 MHz and this is enough for a nominal calculating power of 896 GFLOPS. The DirectX 10.1 compatible graphics chip is linked to 512 MiByte GDDR5 VRAM, which is running at 900 MHz, via a 128 Bit interface. A 92 millimeters fan is cooling an aluminum profile to dispense the heat.
Powercolor says to use a PCB design with a contingent of two ounces of copper in order to grant higher stability and performance. The PWM section is also covered by an aluminum profile to keep the temperatures low.
Quite surprising are the two 6-pin PCI Express power connectors that can be seen on the product pictures. The amount of energy that can be applied with those connectors indicates that the card is equipped with a slimmed down RV770 chip that is produced in 65 nanometers rather than with a 40 nm RV740 chip which is common for the HD 4700.
