PhysX demo screenshots done on NVIDIA Fermi
The PhysX Fluids Demo shows the performance of PhysX to simulate water and fluid effects by using SPH particles with Navier-Stokes solvers. Different flows and droplets of water do interact, create realistic waves and behavior though surface tension in real-time. The water is created through the simulation of 128.000 particles.

NVIDIA Fermi architecture more details
Check this out, this is a table that compares NVIDIA's upcoming Fermi (GT300) architecture with the GT200 and G80 architectures. For the full details you have to check out the whitepaper (PDF) NVIDIA published on its website.
GeForce, Quadro and Tesla chipsets will jump from 240 cores to a much larger 512 and should be much faster in each core courtesy of some industry-first techniques. Fermi chips will be the first GPUs to have a real cache hierarchy, with Level 1 caches to keep specific information on hand and a single, shared Level 2 cache for larger tasks; they will also have a new GigaThread engine that can transfer data in both directions at once and handle "thousands" of tasks at once.
ECC memory will also work for the first time and should help Quadros and Teslas avoid errors for large scale chores, especially in PC clusters.
The chipmaker is short on full performance claims but says Fermi is much better tuned for general purpose computing. Its double-precision floating point math should run about eight times faster than the company's previous best and should provide much better performance with current and upcoming standards, including OpenCL, Microsoft's DirectCompute and NVIDIA's own CUDA.

First photos of NVIDIA Fermi Tesla card
Some photo's of NVIDIA's upcoming Fermi Tesla card have been spotted on the web. This particular model is the next-gen Tesla part, it's not intended for gamers but for super computing. The aestehic build design should be the same though, have a peek.

NVIDIA demos GPU accelerated 720p HD Flash
NVIDIA recently gave a demonstration of an upcoming version of Adobe's Flash player that takes advantage of GPGPU computing to accelerate 720p HD video playback. The (fittingly high-definition) video shows laptops with Nvidia Ion integrated graphics attempting to run a 720p Star Trek trailer, also on YouTube.
The first system's attempt is unwatchable, but the second can pull off completely smooth playback. It has no trouble with the trailer for the new Harry Potter movie, either. What's the difference? Apparently, the second laptop uses a new version of Flash that taps the GPU for rendering.

MSI AfterBurner OC Software introduction
It is with much pleasure we can announce that today MSI has released their MSI Afterburner software, an application to overclock MSI graphics cards. And I it say with much pleasure here as Guru3D has been deep inside the development of this all new overclocking application..
Afterburner is powered by our own Rivatuner engine, but this software comes with a few extra's. AfterBurner will support both ATI and NVIDIA graphics cards, Voltage regulation on the GPU, overclocking on core, shader and memory domains, GPU load levels (ATI), fan speed adjustment, device information .. and a really wicked graphical (configurable) monitor

nVidia GT300's Fermi architecture unveiled
An interesting tidbit of info just surfaced on the web through Bright Side of News, regarding NVIDIA's upcoming GT300 chip (high-end graphics card part. I'll do the blunt copy/paste here:
nVidia GT300 chip is a computational beast like you have never seen before. In fact, we would go as far out and state that this is as closest as GPU can be to a CPU in the whole history of graphics technology. Now, time will tell whatever GT300 was the much needed revolution.
Beside the regular NV70 and GT300 codenames [codename for the GPU], nVidia's insiders called the GPU architecture - Fermi. Enrico Fermi was an Italian physicist who is credited with the invention of nuclear reactor. That brings us to one of codenames we heard for one of the GT300 board itself - "reactor".
When it comes to boards themselves, you can expect to see configurations with 1.5, 3.0 GB and 6GB of GDDR5 memory, but more on that a little bit later.
This is the meat part you always want to read fist. So, here it how it goes:
- 3.0 billion transistors
- 40nm TSMC
- 384-bit memory interface
- 512 shader cores [renamed into CUDA Cores]
- 32 CUDA cores per Shader Cluster
- 1MB L1 cache memory [divided into 16KB Cache - Shared Memory]
- 768KB L2 unified cache memory
- Up to 6GB GDDR5 memory
- Half Speed IEEE 754 Double Precision
As you can read for yourself, the GT300 packs three billion transistors of silicon real estate, packing 16 Streaming Multiprocessor [new name for former Shader Cluster] in a single chip. Each of these sixteen multiprocessors packs 32 cores and this part is very important - we already disclosed future plans in terms to this cluster in terms of future applications. What makes a single unit important is the fact that it can execute an integer or a floating point instruction per clock per thread.
TSMC was in charge of manufacturing the three billion transistor mammoth, but it didn't stop there. Just like the G80 chip, nVidia GT300 packs six 64-bit memory controllers for a grand total of 384-bit, bringing back the odd memory capacity numbers. The memory controller is a GDDR5 native controller, which means it can take advantage of built-in ECC features inside the GDDR5 SDRAM memory and more importantly, GT300 can drive GDDR5 memory in the same manner as AMD can with its really good Radeon HD 5800 series. The additional two memory interfaces will have to wait until 28nm or 22nm full node shrinks, if we get to them with an essentially unchanged architecture. You can expect that the lower-end variants of GT300 architecture will pack less dense memory controller for more cost efficiency, especially on the memory side.
Ferni architecture natively supports C [CUDA], C++, DirectCompute, DirectX 11, Fortran, OpenCL, OpenGL 3.1 and OpenGL 3.2. Now, you've read that correctly - Ferni comes with a support for native execution of C++. For the first time in history, a GPU can run C++ code with no major issues or performance penalties and when you add Fortran or C to that, it is easy to see that GPGPU-wise, nVidia did a huge job [via bsn].

ASUS to offer sub 99 USD P55 motherboard
ASUS is preparing a new P55 motherboard that will address the 'budget' market. It is the P7P55 LX. Supporting socket LGA 1156 processors, the P7P55 LX is intended to be priced even lower than the P7P55D LE (under 100 EUR).
It's all a little basic like the 5 phase CPU power circuit. You do however gain the latest ASUS extra's like MemOK, ExpressGate, and TurboV.
You will spot one PCI-Express 2.0 x16 (looks like two .. but the second one only is a x4 (!). Good enough for say PhysX or something else. Then two PCI-E x1, and three PCI. All six SATA 3 Gbps ports are assigned as internal ports. An additional controller provides an IDE connector. Integrated is also 8-channel audio with optical SPDIF output, and gigabit Ethernet make for the rest of the feature-set.
Paired with a Core i5 750 at 199 USD this might be a very sweet deal.

Radeon HD 5850 review (CrossfireX)
Today we'll test and review the Radeon HD 5850, we'll check both the single GPU performance but also will check it out in CrossfireX multi-GPU mode. This card promises to go neck-on-neck with the 349 USD GeForce GTX 285 in terms of performance. The Radeon HD 5850 however comes with full DirectX 11 compatibility, Eyefinity and some sheer brutal rendering performance in both gaming and compute features.
It's everything the Radeon HD 5870 really is, just a slight notch slower but more affordable.

Volume limit on MP3 players in the EU
The European Commission has decided to set volume limits for MP3 players in all European Union member states, which means your Zune HD won't be able to output anything louder than 80 decibels under the default settings when the ruling goes into effect. According to Consumer Affairs Commissioner Meglena Kuneva, "It's easy to push up the sound levels on your MP3 player to damagingly loud levels, especially on busy streets or public transport.
And the evidence is that particularly young people -- who are listening to music at high volumes sometimes for hours each week -- have no idea they can be putting their hearing at risk. It can take years for the hearing damage to show, and then it is simply too late."
