ASUS ha lanciato le prime schede grafiche al mondo che utilizzano consensatori polimerici a layer multipli, o Super ML Cap: si tratta delle video card basate sulla gpu GeForce GTX 285 e siglate ENGTX285 TOP/HTDI/1GD3 e ENGTX285/HTDI/1GD3 e delle video card Radeon HD 4890 based siglate EAH4890 TOP/HTDI/1GD5 e EAH4890/HTDI/1GD5.

In accordo al produttore, l'adozione dei condensatori sopracitati ha permesso di incrementare di 3.3 volte il livello di overcloccabilità delle schede della linea ENGTX285, capaci, inoltre, di operare ad una temperatura che è risultata essere inferiore anche di 15°C a quella esibita dalle soluzioni omologhe che fanno uso di un cooler reference.

Analoghe considerazioni sono estendibili anche alla serie EAH4890, che può offrire agli utenti più esigenti un margine per l'overclock della gpu, effettuabile con l'ausilio della tecnologia proprietaria Voltage Tweak Technology, pari a 3 volte quello delle soluzioni standard ed una temperatura operativa più bassa anche di 10°C rispetto alle implementazioni reference.

Taipei, Taiwan, April 30, 2009 - ASUS, world-leading producer of top quality graphic solutions, has today introduced the world's first graphics cards to utilize Multilayer Polymer Capacitors (Super ML Caps) with the self-designed ENGTX285 and EAH4890 Series. Both equipped with the Super ML Cap, the ASUS designed ENGTX285 Series allows users to enjoy up to 3.3 times GPU overclocking margins and up to 15°C cooler GPU temperatures when compared to reference designed boards; while the ASUS designed EAH4890 is equipped with the Super ML Cap, Voltage Tweak Technology and a specially designed fansink to offer up to 3 times GPU overclocking margins and 10°C cooler GPU temperatures. Additionally, with the inclusion of the EMI Shield, covered chokes, low RDS(on) MOSFETs, and solid capacitors, users can achieve extreme performances while enjoying total peace of mind.

Up to 3.3 Times Overclocking Margin and 15°C Lower GPU Temperatures with ASUS ENGTX285
The ASUS designed ENGTX285 and EAH4890 Series are the world's first graphics cards to be equipped with the Super ML Cap. With the high capacitance inherent in Super ML Caps, guaranteed stable system operation even under a sudden increase in load current will deliver the most reliable power and the best overclocking margin ever. Additionally, the low Equivalent Series Resistance (ESR) of the Super ML Caps enable higher ripple current with better power efficiency to help lower the temperature of the GPU and memory modules by up to 15°C and 8°C respectively on ENGTX285. The Super ML Cap also exhibits superior low-temperature impedance, allowing PCs to be switched on even at temperatures of under -15°C. Furthermore, the low height of Super ML Cap allows it to be placed closer to the GPU without interfering with the heatsink, allowing it to respond faster with a reduced lower voltage noise for even better stability (the GPU power noise can be reduced from 246mv to 210mv, an amazing 15% drop on ASUS designed ENGTX285). With the Super ML Cap present on the ENGTX285 Series, the overclocking limits of the GPU/shader/memory clock can be dramatically boosted from 670/1550/2700 MHz up to 720/1656/2920 MHz—an astonishing 3.3 times in terms of GPU overclocking margin.

Easy and Extreme Overclocking via Voltage Tweak with ASUS EAH4890
Besides the Super ML Cap mentioned above, the ASUS EAH4890 Series also comes with the exclusive Voltage Tweak technology and a specially designed fansink to provide users with the best possible tweaking options. With Voltage Tweak, users can boost GPU voltages from 1.312V up to 1.4V easily with just a few clicks in the SmartDoctor application, and along with the luxurious Super ML Cap, the overclocking limits of the GPU/memory clock can be dramatically boosted from 900/4000 MHz up to 1000/4800 MHz—an astonishing 3 times in terms of GPU overclocking margin. Additionally, the specially designed fansink on the EAH4890 Series comes with six 230mm heatpipes to maximize heat dissipation efficiency, which combined with the low-ESR Super ML Cap (the GPU power noise is reduced from 143mv to 114mv, an amazing 20% drop on the ASUS designed EAH4890) can generate 10°C cooler GPU temperatures when compared with the reference designed boards.

Enjoy Up to 108% Default Performance
The ENGTX285 TOP's default core, shader, and memory clock performances are boosted from 648 MHz up to 670 MHz, 1476 MHz to 1550 MHz, and 2484 MHz to 2600 MHz respectively, while the EAH4890 TOP's default core and memory clock performances are elevated from 850MHz up to 900 MHz and 3900 MHz to 4000 MHz. These extraordinary performance upgrades help raise the ENGTX285 TOP and EAH4890 TOP's 3DMark Vantage Extreme Preset scores from 6003 to 6298 and 4612 to 4980—an astonishing 5% and 8% improvement in speed respectively when compared to any other reference designed board. With such overwhelming performance boosts, get ready to feel the adrenaline rush of gaming like never before—only with the ASUS ENGTX285 TOP and EAH4890 TOP!

Ultimate Armaments: The Finest Component Selections
Keeping in line with ASUS' Rock Solid promise for quality, the self-designed ENGTX285 and EAH4890 Series will come equipped with several solutions that will help deliver top quality visual performances. With the EMI shield, 66% EMI can be reduced for more stable signals; while Covered Chokes enhance up to 25% power efficiency and generate less heat in comparison to traditional Toroidal Coil Chokes. Additionally, the low RDS(on) MOSFET lowers temperatures by up to 15°C in comparison with the traditional thick versions. Last but not least, the use of solid capacitors lowers power loss for more stable operations and durability, even under long-term use. The lifespan of the solid capacitors can also reach 60,000 hours, with a guaranteed 5,000 hour operation time under extreme 108°C environments. Therefore, users will be able to enjoy extreme...
