SAPPHIRE Technology ha annunciato la video card di fascia alta denominata SAPPHIRE R9 290 Vapor-X OC, una soluzione factory-overclocked, basata sulla gpu a 28nm Hawaii di AMD, che è stata progettata in accordo all'architettura Graphics Core Next (GCN) di seconda generazione e integra 2560 stream processor.

In accordo al comunicato stampa pubblicato da SAPPHIRE, il core grafico della gpu della video card R9 290 Vapor-X OC lavora di default a 1030MHz, mentre il frame buffer, che è implementato con 4GB di RAM G-DDR5, opera a 1400MHz (o a 5.6GB/s in termini di velocità di scambio dati effettiva). Ne consegue che questa scheda video rappresenta una edizione della R9 290 Vapor-X dedicata all'overclocking, un regime operativo che, per questa SKU, viene impostato di default dallo stesso produttore.

Tra le personalizzazioni del design reference della Radeon R9 290 introdotte da SAPPHIRE un posto di primo piano è occupato dal sovradimensionamento dello stadio di alimentazione che, attraverso un VRM a 6 fasi, realizzato con componenti discreti Direct-FET e induttori con il nucleo in ferrite, è sempre in grado di polarizzare al meglio la gpu, i chip di RAM e i circuiti di controllo al variare delle frequenze di clock in gioco.

Un'altra feature di rilievo della SAPPHIRE R9 290 Vapor-X OC è rappresentata dal sistema di raffreddamento, progettato in accordo allo schema proprietario "Tri-X" e basato sulla tecnologia "Vapor Chamber". Questo cooler include in particolare 5 heat pipe (una principale da 10mm, due da 8mm e le restanti da 6mm) e tre ventole da 90mm "tanto efficienti quanto silenziose", assicura SAPPHIRE.

Il kit di connettori di uscita della SAPPHIRE R9 290 Vapor-X OC è composto da due porte DVI-D dual-link, una HDMI 1.4a e una DisplayPort 1.2; questa scheda può naturalmente lavorare con i display Ultra HD 4K.

SAPPHIRE Technology, the leading manufacturer and global supplier of AMD-based graphics products, has just announced an exciting new model in the successful R9 series of graphics cards. The SAPPHIRE R9 290 Vapor-X OC features several of the company's industry-leading technologies and a factory overclock to deliver best in class performance with very low noise.

Based on the award-winning Graphics Core Next (GCN) architecture from AMD with 2560 Stream Processors, the SAPPHIRE R9 290 Vapor-X is an Overclocked edition which boasts 4 GB of the latest GDDR5 memory running at 1400 MHz (5.6 GB/s effective) and high speed engine clocks of 1030 MHz. Together these clocks deliver industry leading performance - but to achieve this performance with stability and reliability demands high quality components throughout the design (especially in the power control circuitry) together with a sophisticated cooling solution.

SAPPHIRE Innovations
The advanced cooling system for the new SAPPHIRE Vapor-X series has been engineered with a combination of SAPPHIRE innovative technologies to provide not just efficient cooling, but also quiet operation. At the core of the cooling system is the SAPPHIRE exclusive Vapor-X technology. SAPPHIRE pioneered the use of vapor chamber technology on graphics cards and has now used it in several generations of highly successful products. The vapor chamber is mounted between the GPU itself and the base of the heatsink and cooler assembly to ensure the maximum transfer of heat away from the GPU into the cooler.

The new Vapor-X cooler uses SAPPHIRE's latest and highly acclaimed Tri-X structure comprising five heatpipes and three efficient fans. The core heatpipe is an industry leading 10mm pipe, flanked by two 8 mm pipes and two 6 mm pipes ensuring even heat distribution across the cooler. The three 90 mm fans use aerofoil section blades for maximum airflow with minimum noise, and are each equipped with two sets of dust repelling ball bearings.

The stylish fan shroud also contains moulded guides to control the airflow across and through the cooler, including over the Power Control circuitry. The combination of Vapor-X and Tri-X technologies results in GPU temperatures between 5 and 10 degrees cooler than with Tri-X alone - delivering industry leading cooling for this generation of graphics cards.

Another new feature of the cooler on this new model is a PCB Component heat spreader. Along the edge of the card the PCB is extended and one of the copper layers left exposed. An additional heatsink mounted directly to this copper layer allows heat absorbed into the PCB from the GPU and other components to be transferred to the heatsink and cooled by the airflow. This feature alone can reduce core temperature by several degrees.

New VRM Engine
To deliver sufficient power for maximum performance, the Vapor-X series uses Digital Power control and a new Aero6 VRM section delivering 6-phase power with high power Direct-FET technology to the GPU, memory and control circuitry. The power design uses the latest version of SAPPHIRE Black Diamond chokes, so called because they feature a black ferrite cooler for cool running and better efficiency. High reliability solid electrolyte capacitors are used throughout. The Aero6 gets its name because the layout of the 6-phase power circuits, chokes and the dedicated FET cooler resembles the appearance of a high performance engine.

Recognising that the R9 series will not always be running at high performance, SAPPHIRE has incorporated another new feature in the Vapor-X models, Intelligent Fan Control (IFC). With IFC engaged, if the system is running simpler applications such as 2D work or watching video, only one of the three fans will operate, resulting in near silent operation. As soon as the GPU temperature rises, when performing more demanding tasks such as gaming or 3D rendering, all three fans will operate, and continue to run with fan speeds regulated by the temperature profile. Extreme users or keen gamers might want to have all three fans running all the time, so the card is equipped with an IFC override switch.

How Cool is that?
The user has a simple visual indication of the temperature of the card as the colour of the LED illuminated SAPPHIRE logo on the side of the card will change from blue when cool, through yellow and on to red when running hot.

Universal Compatibility
The SAPPHIRE R9 290 Vapor-X is equipped with a Dual BIOS - so at the touch of a button it can be switched between compatibility with the latest UEFI or for use in legacy based systems. For optimum performance this card should be used in a mainboard with PCI Express Gen 3.0 expansion slots. Multiple cards can be used in AMD CrossFire in a compatible mainboard.

Latest Displays
The SAPPHIRE R9 290 Vapor-X is equipped with Dual DVI-D, High speed HDMI 1.4a and DisplayPort 1.2 outputs enabling it to support the latest digital monitors. It is ideal for use with three monitor Eyefinity set-ups, with no active adapter needed, or with the latest high resolution 4K displays.

The SAPPHIRE R9 290 Vapor-X is shipping now and will be available from the usual SAPPHIRE etailers and retailers.
