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

Armed with only a hacksaw, the intrepid gamers at Bjorn3D have completed a successful heatsink transplant, the patient, one GTX275 that had a severe fever is now doing much better thanks to the Thermalright HR-03 GTX.
As the cure only required an investment of $50 and could be done in home, the procedure went ahead without delay and they are pleased to announce that what was a life threatening temperature of 86C has been reduced to a

[H]ard|OCP actually managed to get a hold of a retail box XFX HD4770 dual-slot card, the YDFC model
as the YDLC is a single slot card. It is still a 40nm process GPU with 640 stream processors and 512MB of GDDR5, what is special about the card is that XFX has always been nVIDIA only, this is the first AMD silicon they have released. Their 'double lifetime' warranty still applies, they are not taking anything away that you'd expect to see on their nVIDIA offerings. Check out what thi

At $250 the Sapphire HD4890 Vapor-X 2GBruns about $40 more than the vanilla version, but also sports twice the memory as well as a nice improved cooler. That cooler has allowed Sapphire to raise the core GPU speed by 20MHz to 870MHz and the memory by 100MHz to 1050MHz and is capable of hitting 950MHz and 1200MHz with a little tweaking. In addition, the cooler is significantly quieter tha

In a move that is surely going to raise some eyebrows, Intel has apparently decided to add a pair of HD video decoders to the logic on-board the Larrabee graphics chip; this according to a story over at SemiAccurate. This would definitely go against the whole premise of the Larrabee architecture: to do as much work as possible in x86 software without the need for dedicated hardware to any one specific task. Intel said from the beginning that textures required special hardware to run m

If you are looking for a little Wild West action on your PC, and a Clint Eastwood marathon just won't cut it, pick up the second iteration of Call of Juarez; Bound in Blood. Shotguns and six shooters replace SMGs and BFGs and there is no crying allowed. [H]ard|OCP picked up a copy to test the experience that people will have with eight of the top current video cards. Their testing showed that even a HD4770 can manage 2560x1600, though perhaps the most interestin
