In one corner you have AMD's fast card, the $200 Radeon HD 4890 1GB and in the other corner a pair of
HD 4770s that together add up to $220. The pair of cards have access to more shaders, while the single card has better memory bandwidth making the contest look inter

With five months of ATI Catalyst driver blogs under our belt, we are seeing a growing engagement from the community via this blog site. Please keep up the great comments and suggestions and we will endeavor to answer as many as we can. So, without further ado – let me introduce the ATI Catalyst 9.8 Driver Release!

In one corner is the CPU calculated physics software called Havok and in the other corner is what used to be Ageia's and is now nVIDIA's proprietary GPU physics program, PhsyX.

It looks like AMD GPU fans attending QuakeCon 2009 (and you really should) will get a bit of an early dig into the world of the Catalyst 9.8 drivers. According to this post on Catalyst driver lead Terry Makedon's twitter page, users interested in getting the first taste of 9.8 should be following him:

A couple of days ago news began to spread that (surprise!!) SLI support was coming to the world of Lynnfield and the P55 chipset. Why this was a shock to so many people was confusing to me as motherboards had been advertised with "SLI Support" since Computex in June. We saw examples from ASUS, MSI and Gigabyte as well as several other brands.

The AMD FirePro V8750 has arrived, bringing with it the first incarnation of Crossfire Pro, the equivalent of Crossfire X for production level cards. It is not quite as flexible, allowing only a pair of cards to be used and the cards must match exactly, though you do not need a V8750, the V5700, V7750, and V8700
will also benefit from having a twin. The big question on Phoronix's mind is how this card performs under Linux, specifically Ubuntu 9.04. Their first disappointment was the lack of Crossfire Pro support; on the plus side the card was recognized immediately. <
Introduction, GPGPU history, ATI Stream and CUDA overviews
Since our initial review of five of NVidia's CUDA-enabled applications back in June, we've been chomping at the bit to get our first real look at ATI's entry into the GPU computing ring called ATI Stream. Both of these platforms use parallel computing architectures to utilize their GPU's stream processors, in tandem with the CPU, to significantly increase any system's video transcoding speeds. Today, we are going to discuss both of these technologies as well as benchmark a couple video transcoding applications from Cyberlink that actually support both CUDA and ATI Stream.

Earlier this week we heard reports on Semiaccurate that NVIDIA's next-generation GPU part, known as GT300 around here, had actually taped out. That means the designers think and hope they are done and the results are handed off to the manufacturer (TSMC) for the initial run of silicon. Typically we'll see the time between a tape out and a first prototype graphics card to be about 10 weeks:

The biggest change to the ASUS EAH4890 TOP is not the cooling system, instead it is the power system. The dual fans and heatpipes are good, it is the Super ML capacitors and the ability to adjust the cards VCore through bundled software. [H]ard|OCP found themselves amazed at the 960MHz GPU and 4.5GHz GDDR5 final overclock, with no tweaks, tricks or other chicanery, they hit that speed straight out of the box. Those capacitors
certainly made a difference which is good news as
