NVIDIA and ATI War Concentrates into PhysX CPU Lackings

At Real World Technologies, David Kenter has presented a new report that gives large explanations of how PhyX is executed on a standard x86 CPU. PhysX uses a very old method of calculating floating points. It uses the primitive x87 instructions for the vectorization instead of taking use of the much advance vectorization capabilities of SSE and SSE2 that are the core of the x86 CPU.

Previous Blame Game

It is now more than a month that there was some shin-kicking between NVIDIA and it head to head competitor, ATI. ATI blamed NVIDIA for crippling the performance of the CPUs while running PhysX code. This way ATI claimed that NVIDIA is forcing developers to make use of their GPUs. For this the NVIDIA denied any such facts. One of the other blames on NVIDIA was put by Intel whereby they presented a whitepaper that claimed that NVIDIA’s test case for the claim of high GPU performance advantages was totally unfair.

A Word With PhysX Team

When the people of Hot Hardware talked to the team of PhysX team at NVIDIA they agreed upon a fact that they have spent more time and resources in optimizing PhysX to give high end performance on Xenon processor of XBOX 360 and Cell processor of the PS3 as compared to the x86 based processors. Upon talking further the PhysX team said that there are good and very solid technical reasons for the said optimization as far as PS3’s Cell processor is concerned. To support this statement they said that the Cell processor is designed in a fashion that if you run a properly tweaked code on it, it would blow past any x86 platform based CPU with a big margin. And if in any case you miss these optimizations, it would make you wish to have a 486, which by all means would prove faster than the Cell processor.

Evolution of PhysX

NovodeX developed the software version of the PhysX when it acquired Ageia back in 2004. At that time Ageia had on papers, the design to build a Physics Processing Unit that could aceelerate PhysX in hardware. This hardware accelerated PPU was named as Version 2. The underlying code for this hardware based accelerated engine was of NovodeX. The former employees of Ageia who now are working at NVIDIA told that NovodeX started building the original SDK back in 2002- 2003.

It was in 2008 when NVIDIA acquired Ageia, but by then Ageia had already deployed PhysX to XBOX 360 and PS3 platforms. After this NVIDIA started working on porting PhysX on the GPU and started focusing its development in this area. As told by NVIDIA, they have improved upon the multithreading and general performance of the SDK but they certainly face limitation when optimizing an 8 year old engine without breaking backwards compatibility.


NVIDIA has worked out on the best strategy that would force people buy the GPUs. They have made an image that only NVIDIA can provide the amazing and stunning special effects. And if they optimize PhysX for x86 then the passion of users to buy NVIDAI GPUs would die. Another strategy that NVIDIA has applied is to use the psyche of developers to use the enormous hardware power available, which would make users buy GPUs to get the most out of the games.

Fedora 13 Out In Market With Python 3 And Open 3D Drivers

The latest version of the Fedora is out in the market to surprise the users with its amazing performance. Known as Goddard, this device has got inbuilt proprietary drivers in the system. The earlier versions of Fedora have lacked this feature in their systems and hence, one would have to install proprietary drivers separately to start working with the 3D gaming or composite windows. There was a tremendous hard work applied to get the best idea and implementation for replacing the proprietary drivers and the latest Fedora is one of its kinds. After several months of hard work on research and implementation, an open source graphics drivers which do not need any sort of proprietary work has been developed.

Using these drivers working on the Gnome 3 interface and running a composite window manager would be easy. Now, it is possible for the users of Fedora to start using the platform without installing the proprietary drivers. The latest Fedora 13 supports NVIDIA, ATI and the Intel graphics card and the users can play 3D games as well as work on the composite windows at a time. The major result of this release is with the Gnome 3 interface. The user interface of the new Gnome is more robust with several display features and rich graphics. Last year, the version 11 of Fedora had a major overhaul in the software.

Intially, there were some problems with its introduction in Distro and all these problems and drawbacks were taken care of through the version 12 release. With the advancement to version 13, the installation process of the Fedora has improved to a greater extent. The design is very intuitive and provides less intimidating partitions for the new users. The users can make a choice of whether they would like to use the entire partition or to use the partitions made by the operating system. There is good news for the software developers as the use of these embedded proprietary drivers has enabled the use of Python 3 Stack installation and working on the Fedora platform.

The series up to 2.6 can be used and worked with the new features of the Fedora. Not just the installation and the regular files, third party modules are also included in the Python Suite for the open source software developers to make use of. With this the software developer would find it easy to expand to the higher versions of the Python programming. The Gnome 2.30 user interface now is shipped with Fedora 13. There are options such as split pane window in the Nautilus browser which is mostly preferred and considered as the default rather than choosing spatial which was previously the default browser of the Fedora systems.

Fedora 13 had improved face book chatting programmed with instant messaging application. There is also improved iPod compatibility in the latest version of Fedora. New tools have helped in the installation processes through the use of Package Kit. There is also a definite support for the color management and working with the color profiles of the system.

European retailers list Nvidia’s GeForce GTX 460

In the specialized field of making graphics cards, Nvidia has been a true winner over the years. Nvidia along with ATI, are the two big players in this territory today. Every product they launch is highly talked about, and most of them are runaway hits! Speculation is also a big part of the marketing game and companies such as Nvidia are well aware of this. Retailers go out of their way to try and get hold of these much awaited products, adopting different strategies to get the first mover advantage. One such recent occurrence was when some European retailers listed Nvidia’s upcoming GeForce GTX 460 graphics card.

Although they took the liberty to list the card, the information that they have about the product is minimal. Some of the shops say that it will hit their stores in the next 4 to 7 working days whereas few others say it will take more than ten days. The general consensus is that the card will hit the stores pretty soon. Well, the bad news is that Nvidia has itself not announced by when they plan to release it to its retailers. This might create a bit of a misunderstanding between the retailers and Nvidia representatives.

All we know about the card right now is that Nvidia has been working on a GF100 based SKU, that will cut down from the GeForce GTX 470. This is named GeForce GTX 460 and will be a strong contender to rival ATI’s HD 5850. It supports DirectX 11and that it has 1024MB of memory. The new design was supposed to release in June, 2010 but the listings have surprised one and all.

The good thing, however, is that we have got a rough idea of the product pricing. It ranges from € 284 to € 332 across different retailers. However, one can zero in on something around €300 for the product. This price was pretty much expected but the product has to deliver on the performance front! As the HD 5850 is a direct competitor in terms of price and features, the GTX 460 will have to prove itself in the days to come.

Coming back to the listings, we have to wait and watch the proceedings for the next few days. Going by Nvidia’s history, it is highly unlikely that the new SKU will come to the market before the scheduled release. However, if it does hit the stores in the next few days, it might just work to their advantage as there is high demand for a niche product such as this.

As I stated above, markets and speculation go hand in hand. It is not the first time that something like this has happened but retailers should be a bit more careful as it might tarnish their image. There is a lot of hype attached to the product and it is but natural for a shopkeeper to try and capitalize on the situation! All said and done, Nvidia’s products will continue to attract such attention and they have surely realized that it is for their own good!
