ExtremeTech is taking a close look at the two new video transcoding techniques from AMD and nVIDIA, ATI Stream and CUDA. The software transcoder they will be using comes from Cyberlink, called MediaShow Espresso, a $40 product that supports both AMD and nVIDIA's technology. The transcodes that they will attempt are for the iPhone, MPEG2, Xbox and native H.264, and they use 3 movie trailers as the media. This GPU technology certainly beats CPU encoding; but which one is the fastest?
General purpose graphics processing units (GPGPUs) have had a huge impact in everything from professional and home applications to video processing and even physics simulations. No GPU parallel computing architecture has been more in the spotlight than NVIDIA’s CUDA either. CUDA technology is being used in many different types of applications including video and audio encoding, oil and gas exploration, product design, medical imaging, and scientific research.

Charlie D., formerly of The Inq, has a new site and he wants you to know that all the codenames you heard for the upcoming 40nm DX11 parts from AMD are wrong. We first showed you the wafer shot and details of the 40nm DX11 parts last week during Computex - definitely check that out if you haven't already.

There is a story over at The Inquirer that is speculating once again that EVGA will find its way into the arms of Intel when the Larrabee product is released late in 2009 or early in 2010.
A unique GTX 275 offering
The GeForce GTX 275 started as a fill-in GPU to combat the Radeon HD 4890 when it was released earlier this year. As enthusiasts started adopting it, it found a great spot in terms of performance and price between the GTX 285 and GTX 260+. Galaxy has an overclocked model with a custom cooler available that does cost a bit extra, but allows you get even more out of the graphics chip.

You might recall seeing the Galaxy 9600 GT LP back in May when Ryan reviewed it, but now that the temperatures have started to go up while prices are going down, it is worth a second look. The card is 1" shorter than the normal model at 8" and almost half as wide at 2.25" as opposed to 4". It also deserves its low power moniker as the system [H]ard|OCP placed it in drew 31 Watts
The ASUS GeForce GTS 250 Dark Knight
We have said over and over again that the mid-range GPU market is a mess - a great mess of fantastic performance and value. Today we are taking a look at a pair of new graphics cards from ASUS and Sapphire that fit snuggly into the sub-$150 field. The ASUS GeForce GTS 250 Dark Knight edition and Sapphire Radeon HD 4850 Vapor go up against the HD 4770 to see who comes out on top.

Knowing that an nVIDIA GTX 275 can hit a Core of 702MHz from the 633MHz stock speed, that it's GDDR3 can reach 1296MHz from a 1134MHz stock and that the Shader clock goes all the way to 1656MHz from 1404MHz is good, but it doesn't tell the full story. Overclocking everything as far as it can go can be an effective method, but it lacks finesse. Doing so makes it hard to judge which part has the most impact on performance or if overclocking that part has done nothing whatsoever. AnandTec
AMD is on a tear now
Today at Computex, AMD has unveiled its first DirectX 11 compliant part, but the announcement is more about the overall features that DX11 introduces rather than the specific part that AMD has already fabricated in conjunction with TSMC on their fledgling 40nm process. Read on for the full scoop.

While wandering around the nearly-deserted Hall 1 of Computex, we ran into some friends at Gigabyte that had a couple of interesting things to show us.
First up was a custom built Radeon HD 4890 1GB graphics card that will come overclocked to 900 MHz compared to the 850 MHz stock frequency.
