Benchmark Reviews is no stranger to the Radeon HD 4870 and today we add one more to the ranks: the ASUS EAH4870 Dark Knight Top. This 'DK TOP' model comes equipped with ASUS' famed Dark Knight cooler and claims of a 9% performance lead over stock 4870's thanks to an impressive factory overclock. In today's review, we'll put this claim to the test and find out what kind of performance the EAH4870 DK Top brings to the table.
Today, Asus has claimed that is has perfected the Radeon HD 4890 and the RV790 GPU, with a custom-designed videocard that it calls the EAH4890 TOP. The EAH4890 TOP has everything you'd expect from a reference Radeon HD 4890: the GPU and shaders are clocked at 850MHz and accompanied by 1GB of GDDR5 memory that runs at an effective speed of 3.9GHz (975MHz quad-pumped). Where the Asus EAH4890 TOP differs is in its construction. Asus has made dramatic changes from AMD's reference Radeon HD 4890, with a re-designed PCB, new power management, an improved heatsink, and more powerful air cooling. The result is a videocard that holds a lot of promise for some extreme overclocking and tweaking.
ASUS has a reputation for bringing cream-of-the-crop products to the marketplace, and branding them with the TOP badge. The new Radeon RV790 GPU is the next well-bred concept from the ATI labs, and in this article Benchmark Reviews tests the performance of the new ASUS Radeon HD 4890 GDDR5 EAH4890TOP video card against the rest of the high-end segment. Overclocked to 900MHz this Radeon 4890 is the most-powerful single GPU video card produced by AMD, it's going to be a tough fight to beat out NVIDIA.
Not many people would argue that the AMD 5xxx series has been an incredible success … fantastic performance, wicked DX11 capabilities while still managing to remain competitively priced. In the latest of our articles to focus on graphics cards with proprietary cooling systems we look at a product called the Formula HD5750. Yep, if you look closer you will see that the cooler is shaped to resemble a Formula race car.
The ASUS EAH5770 CuCore/2DI/1GD5/A videocard might just hit that wonderful sweet spot where price and performance balance perfectly. The card comes packing 1GB of GDDR5 RAM and with a GPU ticking away at 850MHz. In terms of performance, the Radeon HD 5770 GPU slots in just below ATI's flagship Radeon HD 5870 and 5850 chips, but above the mainstream Radeon HD 5670. The Radeon HD 5770 graphics chip is based on the ATI RV840 'Juniper' GPU, a 1.04-billion transistor die manufactured on a the 40nm process.
The ASUS EAH5850 TOP, also known as the EAH5850 DirectCU TOP/2DIS/1GD5 (phew!) comes with 1 GB GDDR5, pre-overclocked, and with a custom cooling solution that promises to lower temperature by 20% and noise level by 35% than the AMD stock cooler. Let's check it out.
Today we'll review three graphics cards with ATI Radeon GPUs. The reason for the selection is simple: all three simply happened to be in our lab at the same time. All three cards have custom design and original coolers, so reviewing them promises to be interesting.
AMD stellte heute die HD 5830 Grafikkarte vor, die aber wieder Probleme mit der Verfügbarkeit bereitstellt. Ein Sample seitens AMD war von uns nicht zu ergattern. Stattdessen widmen wir uns weiter der HD 5870, die inzwischen eine etwas bessere Lieferfähigkeit vorweisen kann. In der Redaktion befand sich diesmal eine HD 5870 von Asus, dies sich ebenso wie die von uns bereits getestete XFX Grafikkarte im Referenzdesign befindet.
It was almost a year ago that ATI began introducing their new Radeon HD 5000 series cards, starting with the then-flagship 5870 model, for a price just under $400. Now here it is 11 months later and the market has held fairly steady, despite nVidia's release of the GTX 400 series in the interim, you still can't find a 5870 for much less than what they initially launched. However what you do find now is a bigger variety of manufacturers offering non-reference cards, overclocked editions and various game bundles. ASUS has combined all three of these into their latest EAH5870/G/2DIS/1GD5/V2 STALKER Edition that we will be looking at today.
Vor einigen Tagen haben wir uns die erste Radeon 6770 bei uns im Testlabor angesehen. Nur wenige Stunden später erreichte uns eine Pressemitteilung von Asus, wo man eine passiv gekühlte Version dieser Grafikkarte vorgestellt hat, die ASUS EAH6770 DC SL/2DI/1GD5. Für diese Version wurde ein komplett passiver Kühler verwendet, der keine Geräusche erzeugt und trotzdem die Temperatur der Karte im Griff hat. Erreichen will man das mit einem doppelt so großen Kühlkörper und hochwertigen Heatpipes. Genau diese Grafikkarte möchten wir uns etwas näher ansehen.
