The ATI Radeon HD 4670 and ATI Radeon HD 4650 graphics cards feature AMD’s TeraScale graphics engine, with 320 stream processing cores, and are based on AMD’s advanced second generation 55nm process.
The result is that even in today’s most demanding games like Crysis, the ATI Radeon HD 4600 series delivers up to double the performance of competing products at the same price.
Both the ATI Radeon HD 4670 and ATI Radeon HD 4650 deliver substantial gaming horsepower with minimal power draw – the ATI Radeon HD 4670 operating at under 60 watts and the ATI Radeon HD 4650 operating under 50 watts under full load – eliminating the need for additional power connectors and making installation a cinch. The ATI Radeon HD 4670 is immediately available with a frame buffer of 512MB GDDR3 memory with an MSRP from USD $79, while a 1GB DDR3-based variant is scheduled to ship later this month. The ATI Radeon HD 4650 features a frame buffer of 512MB GDDR2 memory and is expected to be available later in the month at an MSRP from USD $69.
Leading DirectX 10.1 support
Only AMD graphics offer top-to-bottom DirectX 10.1 support and the ATI Radeon HD 4600 series continues that legacy. Leading game developers are working with AMD to create a new generation of game titles utilizing DirectX® 10.1 to deliver improved features and performance for a better game experience. Developers including Electronic Arts’ Phenomic Studio and its forthcoming fantasy online real-time strategy game BattleForge™, and SEGA and its futuristic military real-time strategy game Stormrise™, both exploit DirectX 10.1 for advanced gaming performance and visual realism.
“As one of the largest computer system manufacturers in North America targeting the mainstream gaming space, we are committed to building systems that deliver tremendous value to our customers,” said Eric Cheung, CEO, CyberPower. “The leading edge technology that AMD is delivering to the mainstream marketplace with the ATI Radeon HD 4600 series is unsurpassed and we are proud to support AMD’s efforts to bring a high-end gaming experience to the masses.”
“You don’t have to be a professional gamer to appreciate the incredible performance delivered by the ATI Radeon HD 4600 series for under $100,” said Orlando Garcia, president and CEO, Frag Dominant.
Stunning HD viewing experience

Unsurpassed performance-per-watt
Built with efficiency, scalability and performance in mind, the ATI Radeon HD 4600 series sets a new performance-per-watt standard for mainstream graphics products, thanks to the enhanced bandwidth of DDR3, new power management capabilities that provide greater performance and efficiency, and 55nm technology. The series features AMD’s second generation ATI PowerPlay™ technology which allows for automatic power adjustments based on the activity of the graphics processing unit (GPU), resulting in significant power savings when the GPU is idle. Moreover, ATI PowerPlay enables advanced clock gating, as well as increased voltage and memory scaling, delivering performance on demand with exceptional efficiency.
Ecosystem support
The ATI Radeon HD 4600 series is supported by a dozen add-in-board companies offering custom designs of the products.
