Some time after the release of Radeon HD 4800 series, AMD is up to surprise thrifty gamers with new video cards Radeon HD 4670 and Radeon HD 4650. Based on the GPU RV730, they have inherited the architecture of the RV770 chip and lost only some functional blocks. AMD's new product promises to be rather fast, and the immediate competitor to Radeon HD 4670 at price is GeForce 9500GT with GDDR-3 video memory. The recommended price for Radeon HD 4670 is $79.
The video card has proved to be of comparatively small size, takes up only one expansion slot and does not require additional power supply.
On the reverse side of the video card, there are four memory chips.
On the front side of the video card, under the cooling system, there are another four memory chips.
Made following the 55-nm process technology, the graphic chip RV730 is of quite small size, albeit contains 514 million transistors.

The overall video memory capacity is 512 MB and is made up of 8 chips. The memory bus width is 128-bit wide. The GDDR-3 memory chips are made by Hynix and offer 1.0 ns access time, which is equivalent to the effective frequency 2000 MHz at which they run.
Cooling system from Radeon HD 4670
The radiator of the cooling system for Radeon HD 4670 is made of copper, which helps it cope with its job without much noise. We tested the video card for heating using the test scene Firefly Forest from the benchmarking suite 3DMark at 2048x1536 with 8X FSAA and 16X AF enabled. After a few runs, the temperature of the GPU reached 83 C, while during the idle mode the GPU temperature amounted to 61 C. Note that even under maximum load the video card remained pretty quiet.
