Introduction and Features
The massive influx of mid-range GPUs has made for a feeding frenzy by consumers looking for budget graphics solutions. Mid-range offerings from NVIDIA and ATI have completely saturated the market with sub-$100 graphics cards that can almost play Crysis Warhead at decent resolutions. Some video cards priced just over the $100 mark can easily play Crysis and other GPU-intensive games like Far Cry 2 and World in Conflict at higher resolutions too.
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.
CausticGL Ray Tracing API
Caustic let us peruse a new technical brief it was working on that describes in much more detail the software side of its CausticRT ray tracing platform. Based on OpenGL ES 2.0, CausticGL aims to do for ray tracing what OpenGL did for rasterization and the company even hopes to gain Khronos Group standardization for its custom API.
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.
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.
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.
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.
A unique 9600 GT
Low power and low profile might not seem like very important features for a GPU most of the time, but you would be surprised how many new PCs on the market today can't fit a standard expansion card. Galaxy is hoping to pin that market by offering a decently-powerful 9600 GT GPU without a PCIe power connection and with a half-height PCB design.
AMD RV740 is all its cracked up to be
The new AMD Radeon HD 4770 is the world's first 40nm GPU and brings even more performance to a world of sub-$100 graphics cards. Does AMD's technology advantage make the 9800 GT and GTS 250 looks like schmucks?
Who is Caustic Graphics?
Caustic Graphics is formally announcing availability of the CausticOne ray tracing accelerator card today and we are finally allowed to unveiling the technology we learned about at GDC last month. If you think the ray tracing and rasterization debate was interesting before, wait until you see what this new player has to say.
Introducing the Radeon HD 4890 1GB
AMD and NVIDIA again have new graphics cards for us to throw into the GPU testing beast on our bench and see what comes of it. The new RV790-based HD 4890 card takes on the cut-in-half GTX 295 known as the GeForce GTX 275 in a battle for your hard earned $250.
Details from GDC 2009
Intel was promoting Larrabee quite heavily at GDC in San Francisco this week even though there is still no hardware to be found. For the GDC audience, Intel decided to share a Larrabee instruction emulation layer so that developers can now start to see how the new x86-based GPU design can be efficiently utilized.
A preview of Windows 7 gaming
The Windows 7 beta has been a huge success with pundits and users all over the tech world singing its praises. But what about gaming? Does moving to Windows 7 beta mean a drop in PC gaming performance like it did with Vista or do Microsoft and the driver teams at AMD and NVIDIA have it all ironed out?
A Bit of History
Initial rumors had the RV790 pegged as a speed optimized RV770, which currently powers the Radeon HD 4800 series of cards. Recent information has hinted that there is far more than a simple speed increase, and AMD could be catching us unawares with a potentially exciting new part. I take a look at AMD's releases over the past two years and make a few guesses as to what we might expect to see.
GTS 250 > 9800 GTX+ > 9800 GTX > 8800 GTS
The new GeForce GTS 250 1GB is being launched today and is not hiding the fact that it is a rebranded 9800 GTX+. But with a lower price and more memory, does NVIDIA have all the fixings for a great budget solution? Or will AMD crash the party?
Intro, NVIDIA Quadro FX 4800 and FX 3700
Both NVIDIA and AMD have updated their respective professional graphics lines in the last month or so and we sit down with a pair of Quadros and a pair of FirePro cards to see which has the ability to be the best performer AND which is the best value.
GTX 285 Shows its 55nm Face
The new GeForce GTX 285 GPU uses the same great architecture (the GT200) that is behind the GTX 280 though shrunk down to a 55nm process technology. What the hell does that mean for you? Higher clocks, lower power and lower prices!
NVIDIA has been working on stereoscopic 3D gaming for several years but now is the official release of retail product that you can buy NOW! Come in and see how we reate the new technology offering from NVIDIA and see how it could change the way you game forever.
GTX 295 Retail Release
Now that the GeForce GTX 295 is officially being launched, we can tell you all about the features and performance we didn't get to disclose during our preview posted a few weeks ago. This time we have added power consumption, Crysis and of course, Quad SLI testing!!
A change of holiday plans
NVIDIA gave us a little time with the new GeForce GTX 295 graphics card - the first dual-GPU solution from the company since the 9800 GX2 featuring a pair of 55nm GT200-based cores on a pair of PCBs on a single card. Can this new GPU get NVIDIA the performance crown again and will it cost you the remainder of your 401k to buy?
