SAPPHIRE technology ha ampliato la propria linea di video card Vapor-X con la soluzione denominata SAPPHIRE R9 290X Vapor-X OC. La new entry di SAPPHIRE è una versione factory-overclocked della Radeon R9 290X di AMD: più in
dettaglio, il core grafico della gpu Hawaii, che è realizzata in accordo all'architettura AMD Graphics Core Next (GCN) di seconda generazione e integra 2816 stream processor, lavora a 1080MHz mentre il frame buffer, implementato con 4GB di RAM G-DDR5, a 1410MHz (o a 5.64GB/s in termini di velocità effettiva).
SAPPHIRE ha fatto ricorso a uno stadio di alimentazione sovradimensionato per stabilizzare la risposta dei componenti cardine alle alte frequenze: in particolare il VRM, che si occupa dell'alimentazione della gpu, dei chip di RAM e dei
circuiti di controllo, è a 10 fasi mentre i componenti discreti sono di elevata qualità (transistor DirectFET, condensatori a stato solido e induttori ad alta efficienza).
Il cooler della video card, oltre a rappresentare un ulteriore elemento di distinzione rispetto al modello reference, si fa notare poichè abbina la tecnologia Vapor-X, con la quale il marketing di SAPPHIRE descrive l'adozione della
tecnica del vapor chamber, a una struttura fisica Tri-X, che prevede l'utilizzo di tre ventole e cinque heat pipe (una principale da 10mm e quattro secondarie, di cui due da 8mm e due da 6mm).
La Radeon R9 290X Vapor-X OC di SAPPHIRE è dotata inoltre di un dual-BIOS: mediante uno switch l'utente può rendere la video card compatibile con le motherboard dotate di interfaccia firmware UEFI oppure con le schede madre legacy. Il kit di connettori di uscita della scheda, che è in grado di gestire senza problematica alcuna i recenti display Ultra HD 4K, è composto da una porta DVI-D dual-link, da una HDMI 1.4a e da una DisplayPort 1.2.

SAPPHIRE technology, the leading manufacturer and global supplier of AMD-based graphics products, has just added another new model to its highly acclaimed Vapor-X family of graphics cards in the successful R9 series. The SAPPHIRE R9 290X
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 2816 Stream Processors, the SAPPHIRE R9 290X Vapor-X is an Overclocked edition which boasts 4 GB of the latest GDDR5 memory running at 1410 MHz (5.64 GB/s
effective) and high speed engine clocks of 1080 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.
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 10 mm 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 molded 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 Aero10 VRM section delivering 10-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
Aero10 gets its name because the layout of the 10-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.
The SAPPHIRE R9 290X 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 Gen3.0 expansion slots. Multiple cards can be used in AMD CrossFire in a compatible mainboard.
The SAPPHIRE R9 290X 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 up to five displays in total, as well as with the latest high resolution 4K displays.
The SAPPHIRE R9 290X Vapor-X is shipping now and will be available from the usual SAPPHIRE etailers and retailers.
