Share it on Facebook Share it on Twitter Share it on WhatsApp Share it on reddit

SAPPHIRE Technology ha aggiunto due nuovi modelli di schede grafiche basate sulla rivoluzionaria architettura grafica GCN (Graphics Core Next) di AMD. I nuovi modelli di SAPPHIRE HD7950 sono solo la seconda famiglia di schede grafiche che incorporano l'ultima generazione di GPU di AMD, costruita sul nuovo processo a 28nm, e che presentano la nuova architettura di elaborazione grafica ottimizzata GCN. La GPU HD7950 ha una nuova struttura interna con 1792 stream processor ed una interfaccia di memoria a 384 bit ad alta velocità, con larghezza di banda di memoria di oltre 264GB/sec.

Due i modelli di scheda al lancio: il modello SAPPHIRE HD7950 standard viene fornito con velocità di core clock di 810 MHz, leggermente superiore al modello di riferimento, e con raffreddamento a doppio slot e a ventola singola, mentre la SAPPHIRE HD7950 OC Edition, overclocked di fabbrica a 900Mhz, è caratterizzata da una nuova tecnologia SAPPHIRE di raffreddamento - Dual-X - ovvero un radiatore ad alta efficienza multi-heatpipe con due ventole, che fornisce silenziosità e basse temperature di esercizio in condizioni operative normali, e superbe prestazioni di raffreddamento anche in condizioni di carico estremo.. Entrambi i modelli sono dotati di 3GB di memoria DDR5 con velocità di clock effettive di 5Gb/s.

Per gli appassionati delle massime prestazioni, una nuova versione del tool di overclocking di SAPPHIRE, TriXX, è disponibile per il download gratuito dal sito web di SAPPHIRE. TriXX consente la regolazione della tensione della GPU e le velocità di core e memory clock, con la visualizzazione continua della temperatura; è possibile inoltre controllare manualmente la velocità della ventola memorizzare profili creati dagli utenti salvando fino a quattro livelli di prestazioni diverse.. Entrambi i modelli SAPPHIRE HD7950 sono dotati di doppio BIOS, che consente ulteriori sperimentazioni agli utenti più esigenti. Nell'edizione OC, il secondo BIOS è predisposto per consentire un overclock massimo più elevato e un profilo ventola più potente.

La serie HD 7000 è la terza generazione di soluzioni compatibili con DirectX 11; la SAPPHIRE HD7950 è inoltre predisposta per DirectX 11.1 e per il nuovo sistema operativo Windows 8. La comunicazione con il PC host è ottimizzata tramite l'implementazione della più recente interfaccia ad alta velocità PCI-Express Gen3.0.

Il lavoro o il gioco con più monitor sta diventando sempre più popolare grazie alla tecnologia AMD Eyefinity: la SAPPHIRE HD7950 supporta configurazioni fino a 6 monitor grazie alle uscite DVI, HDMI e due mini-DisplayPort; inoltre, la SAPPHIRE HD7950 può trasmettere simultaneamente più flussi audio indipendenti associabili a diverse applicazioni su schermi diversi.

La nuova interfaccia HDMI 1.4a supporta la visualizzazione 3D stereoscopica con frame rate portato a 60 Hz per occhio, per un totale totale di 120Hz ed è predisposta anche per la prossima generazione di display 4K, che possono essere gestiti da un unico ingresso ad alta velocità HDMI 1.4a a 3 GHz e DisplayPort 1.2 HBR2.

APP Acceleration è il nome dato ai tools di ottimizzazione delle prestazioni di una ampia gamma di applicazioni per sfruttare al massimo le funzionalità di stream processing e le specifiche di hardware della nuova architettura grafica. Oltre alle applicazioni tipiche video e di gaming, l’“APP Acceleration” migliora le attività più comuni come la navigazione Internet, le applicazioni Office e la compressione dei file con le suite di software supportati.

SAPPHIRE Technology has now added two exciting new models of graphics cards based on the revolutionary new graphics GCN (Graphics Core Next) architecture from AMD. The new SAPPHIRE HD 7950 models are only the second family of graphics cards to incorporate the latest generation of GPU’s from AMD built in a new 28nm process and featuring the new GCN optimised graphics processing architecture. The HD 7950 GPU has a new internal structure with 1792 Stream processors and a 384-bit high speed memory interface with over 264GB/sec memory bandwidth.

Two models are being introduced at launch. The standard SAPPHIRE HD 7950 ships with a core clock speed of 810MHz, slightly higher than the reference design, and a dual slot, single fan cooler. At the same time SAPPHIRE is introducing a high performance model, the SAPPHIRE HD 7950 OC Edition, which is factory overclocked to 900Mhz and features SAPPHIRE’s new dual-extractor technology - Dual-X - a highly efficient multi-heatpipe cooler with dual fans providing quiet and very cool operation during normal operating conditions, and superb cooling performance even under extreme load. Both models have a large 3GB array of the latest DDR5 memory with effective clocks of 5Gb/s.

For enthusiasts wishing to maximise performance, a new version of the SAPPHIRE overclocking tool, TriXX supporting this latest generation of technology is available free to download from the SAPPHIRE website. TriXX allows tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings. Both of the SAPPHIRE HD 7950 models have a dual BIOS, allowing for further experimentation by the enthusiast. On the OC edition, the second BIOS is pre-programmed to allow a higher maximum overclock and more aggressive fan profile.

The HD 7000 series is the third generation of DirectX 11 compatible solutions from the graphics division of AMD - formerly ATI. The SAPPHIRE HD 7950 is ready for DirectX 11.1 and the new Windows 8 operating system as well as delivering all the features of the current DirectX 11 such as DirectCompute11 and multi threaded communications with the CPU. Communication with the host PC is optimised with the implementation of the latest high speed PCI-Express Gen3.0 interface, and multiple cards can be used to further enhance performance in CrossFireX mode on a suitably specified mainboard.

Working or gaming with multiple monitors is becoming increasingly popular, and the SAPPHIRE HD 7950 supports this with AMD Eyefinity. With its DVI, HDMI and two mini-DisplayPort outputs the card can support configurations of up to 6 monitors. In addition, the SAPPHIRE HD 7950 can simultaneously output multiple, independent audio streams allowing the correct audio content to be associated with different applications on different screens.

HDMI specifications have also increased in the HD 7000 series. Fast HDMI (with 3D) supports Stereoscopic 3D with enhanced frame rates of 60Hz per eye - 120Hz total. It is also ready for the next generation of 4K displays that can be driven from a single high speed input of 3GHz HDMI (with 3D) or DisplayPort 1.2 HBR2.

APP Acceleration is the name given to the enhanced performance of a wide range of applications using the stream processing capabilities and specific hardware features of the graphics architecture. The HD 7000 series has been optimised for this type of task. Typical applications include Video encoding and decoding, compression and multiplexing for media distribution, gaming or video conferencing. APP acceleration can also enhance everyday tasks such as Internet browsing, Office applications and file compression with supported software suites.

The SAPPHIRE HD 7950 and HD 7950 OC are now available through SAPPHIRE’s established channel and etail partners.
