We've said it before and we'll say it again - it's a great time to be a PC gamer. While ATI and Nvidia continue to go at each other's throats, it's the consumers who benefit with faster cards for less money than has traditionally been the case. Now the situation looks to get even better.

With a focus on the budget market, ATI's HD 4600 series looks to offer reasonable gaming performance for an even more reasonable sub-$100 price tag. The HD 4650 will carry an MSRP of just $69, which buys a 512MB frame buffer, 320 stream processing units, a core clockspeed of 600MHz, and a 500MHz memory clockspeed. Naturally with a price so low, cuts had to be made somewhere and the 4650 will sport just a 128-bit memory bus.

For $10 more, the HD 4670 carries the same specs, but faster core and memory clockspeeds of 750MHz and 1000MHz, respectively. Unfortunately for overclockers, overclocking the 4650 won't put it on par with the 4670, as the former uses GDDR2 and the latter GDDR3.

Both cards also continues ATI's focus into the living room with HTPC friendly features such as the company's Unified Video Decoder (UVD), Avivo HD technology, and support for 7.1 surround sound through HDMI.

Tom's Hardware reports that AMD is set to launch the new ATI HD 4600 series of video cards on September 10. The HD 4600 is designed to compete with the GeForce 9500 series of video cards, and is expected to replace the ATI HD 3800 series.

HD 4670 versus HD 4650

The HD 4600 series, like the GT 9500 GT, provides best performance when used with GDDR3 memory, but will also be available with DDR3 and DDR2 memory. Cards based on the RV730XT GPU will be known as the HD 4670 (available in 1GB and 512MB RAM versions), while cards based on the slower RV730 Pro GPU will be known as the HD 4650 (available with 512MB of RAM).

Both GPUs will offer PCI Express 2.0 support, DirectX 10.1 support, physics and dynamic geometry acceleration, 24x CFAA technology, 128-bit memory bandwidth, HDCP support for full-quality HD playback, and CrossFire support. The HD 4670 has a power requirement of only 70 to 80 watts, while the HD 4650 requires only 50 to 55 watts, making them ideal for home theater systems.
