AMD ha annunciato una nuova video card nell'ambito della linea Radeon R9; siglata Radeon R9 270 la nuova SKU è basata sulla gpu a 28nm tipicamente indicata con il nome in codice di "Curacao" - architettura Graphics Core Next (GCN) - e va ad ampliare l'offerta del chip maker statunitense nel segmento del mercato collocato al di sotto della soglia rappresentata da $200.
Come nel caso della Radeon R9 270X, il processore grafico della Radeon R9 270 integra 1280 stream processor, 80 TMU e 32 ROP, e presenta un bus a 256-bit che implementa il collegamento della gpu con il frame buffer, implementato con 2GB di RAM G-DDR5.
Le frequenze di clock dei componenti cardine sono invece inferiori a quelle esibite dalla Radeon R9 270X: più in dettaglio il core grafico della Radeon R9 270 lavora a 900MHz (base) e fino a 925MHz (Boost), mentre la memoria on board opera a 5.6GHz.
Il TDP della card, che assorbe potenza attraverso due connettori PCI-E a 6-pin, è pari a 170W mentre, in termini di librerie grafiche supportate, citiamo DirectX 11.2, OpenGL 4.3 e Mantle. Il costo della Radeon R9 270 parte da $179.

AMD (NYSE: AMD) today launched the AMD Radeon R9 270 graphics card, the newest addition to the award-winning AMD Radeon R9 Series GPUs, an impressive family of GPUs that mark a new era of PC gaming. The AMD Radeon R9 270 GPU joins the AMD Radeon R9 270X, R9 280X, R9 290 and R9 290X graphics cards, all designed for enthusiast gamers who expect next-generation hardware that can shatter the boundaries of realism and performance.
"The AMD Radeon R9 270 GPU continues AMD’s tradition of delivering world-class performance, features and multi-monitor support at an incredible value," said Matt Skynner, corporate vice president and general manager, Graphics Business Unit, AMD. "With Mantle, exceptional performance and ultimate gaming experiences are synonymous with AMD Radeon R7 and R9 Series graphics cards. Once again, AMD proves that Radeon is gaming."
Based on AMD’s award-winning Graphics Core Next (GCN) architecture, the AMD Radeon R9 270 graphics card is further enhanced by Mantle, an industry-acclaimed technology developed by AMD to enable today’s top game developers to harness the GCN-powered cores of both PCs and consoles. Mantle delivers a streamlined development process and games enabled with Mantle will be able to speak the native language of the GCN architecture, benefiting from hardware optimization that unlocks revolutionary performance and image quality.
The AMD Radeon R9 270 graphics card is ideal for gamers looking to play the latest games at 1080p with high settings. A single power connector and 150W TDP also make it ideal for users with longer upgrade cycles that are looking to squeeze more life out of their current gaming rig.
Additional features of the AMD Radeon R9 270 graphics cards include:
- 1,280 stream processing units
- Up to 925MHz engine clock
- 2GB GDDR5 memory
- Up to 1.4 GHz (5.6Gbps) memory clock speed
- 179.2 GB/s memory bandwidth (maximum)
- 2.69 TFLOPS Single Precision compute power
- API support for DirectX 11.2, OpenGL 4.3 and Mantle
The AMD Radeon R9 270 graphics cards will be available on Nov. 13, 2013 at a starting price of $179 USD and €134 (excluding VAT).
