Company ASUS for the third time gives rise to devote a news headline graphic cards equipped with the original cooling system Dark Knight. The two graphics accelerator chip GeForce 9800 GTX, EN9800GTX DK/HTDI/512M and EN9800GTX DK TOP/HTDI/512M, primknulo several models based on the Radeon HD 4870 (RV770). Therefore, it is now possible to speak of a series called Dark Knight.
According to an official press release, in the range of Taiwanese manufacturers has three new graphics card:EAH4870 DK/HTDI/512M, EAH4870 DK TOP/HTDI/512M and EAH4870 DK/HTDI/1G. All of them are based on the graphic chip Radeon HD 4870 and different level of graphics memory and operating frequency. The first two fitted with a 512 MB memory type GDDR5. Volume videobufera third - twice as much, that should motivate owners of large monitors. Judging from the numerous tests, published on the web to generate additional 512 MB Radeon HD 4870 tangible benefits when working in difficult conditions.
The frequencies video ASUS EAH4870 DK/HTDI/512M and EAH4870 DK/HTDI/1G consistent with the recommended AMD values - 750/900 (3600) MHz. The model marked TOP in the title dispersed to 815/925 (3700) MHz. According to disperse the kernel, it is ahead of most prokachannyh accelerators, such as PowerColor Radeon HD 4870 PCS or Sapphire Radeon HD 4870 TOXIC, and even fits into the concept of Super RV770. But dispersal of memory seems very modest. According to the press service of ASUS, a model EAH4870 DK TOP/HTDI/512M an average of 9% proizvoditelnee standard Radeon HD 4870 graphics card, running at nominal frequencies.
In studying the exterior of the new video of a series of ASUS Dark Knight and compared with the bearer of the reference design is easy to notice changes in the food chain, which led to razvodke metamorphosis in the printed circuit boards. The increase in the amount of memory in a model EAH4870 DK/HTDI/1G been without installing additional chips and processing design. Engineers used the double-density memory chips.
The pride of developers, cooling system Dark Knight, consists of dyed black aluminum radiator with the company logo, forced four heat pipes. The number plates in the radiator is 33. This is more than the VGA-fan Arctic Cooling Accelero S1 and Twin Turbo, revered by many computer enthusiasts. Fan speed depends on the load on videopodsistemu that ensures quiet and comfort when working in 2D. To cool the power cells a separate cooler.
It is also worth noting the use of solid capacitors in Japan and the coils inductance less heat release. Also, engineers take care to protect against electromagnetic interference and installed a metal plate which, in their view, should improve the stability of the video card.
Sales of new accelerators in a series of ASUS Dark Knight starts since announcements. Judging by the range of European online stores, model EAH4870 DK/HTDI/512M already can be bought for 244 euros. For dispersed modification EAH4870 DK TOP/HTDI/512M are asked for 12 euros more. Accelerator with 1 gigabyte of memory EAH4870 DK/HTDI/1G appreciated even more expensive - at 266 euros.
