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.
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.
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.
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.
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.

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.
Looking at the basic spec sheet, you could be forgiven for thinking the Asus EAH4770 FORMULA is the same as every other Radeon HD 4770. The EAH4770 FORMULA is built around the ATI RV740 GPU, which is itself a direct descendant of the original ATI RV770 GPU. This means that the GPU core clock is still at 750MHz, and there's still 512MB of GDDR memory running at 800MHz."
With the recent arrival of the new ATI Radeon HD 5 series graphics cards causing a great deal of interest, the previous best performing single GPU from ATI – the 4890 – has been left by the way side a little. Although, on the whole, the ATI DX11 GPU launches have been a great success for ATI, many users will still be sticking to the 4 series, if not older, cards and as ATI seeks to monopolise the DirectX11 Market with nVidia’s Fermi Technology lagging far behind, it’s definitely a good time to be investing in a 4890 or other 4 series GPU.
