As with any new generation architecture Fireoro still has a lot of optimisation work to do. Inventor threw up some interesting figures, particularly under our large model in DirectX mode where it reached 3.
ATI FireGL V3600
The degree of benefit to the end user is dependent on how the technology has been implemented by their CAD software vendor. Another driver enhancement is the introduction of automatic profile switching, which tunes the graphics driver for individual CAD applications though this was actually introduced about six months ago.
This not only means you should get better performance but also better accuracy and stability. Such is the importance of the event that software and hardware developers plan their release schedules around the show – which takes place during the summer months at a different location each year in the US.
This has all changed with the R, which sees the ATI bring what is essentially its second generation unified architecture to market. With a new unified architecture and multithreaded drivers, the Rbased FireGL range certainly looks to be an exciting technology.
Having a unified architecture means that you can make full use of all of your processing units at once.
With a traditional single-threaded graphics driver, if a user is updating the fillets on a part, for example, then the CAD software will first take up all of the CPU resources to do the calculation, and then only update the graphics when there are spare CPU cycles available. But with drivers firepeo in development and benchmark figures all over the place it would be premature to come to any definitive conclusions about the new cards quite atu.
ATI FireGL V – graphics card – FireGL V – MB Overview – CNET
The firspro is SPEC Viewperf continues to be one of the first applications that graphics card vendors spend valuable resources tuning their drivers for as it is used so widely by magazines and tech websites.
With MB and the level of power usually associated with mid-range cards it is targeted squarely at the volume 3D CAD market. While the FireGL V will probably do little to excite the power hungry digital artists, it will certainly get the attention of the CAD sector.
With unified architectures a graphics card has an array of processing units which can be dynamically allocated to geometry or shader tasks as required.
And while OpenGL 2. With scores all over the place due to the early driver and lack of optimisations we decided to test the FireGL V under Viewperf We tested the card inside a 2.
This was previously a manual process, with the user selecting their chosen application from a fireprl list, but the driver now automatically does this for you by monitoring which CAD application EXE commands have been launched and tuning the driver appropriately.
The challenge now is for the boffins at ATI to translate that potential into actual performance in real-world CAD and DCC applications, and only then will we be able to see just how good this new technology is. For its low end and mid-range boards, ATI has moved from 80nm to a 65nm fabrication process, which essentially means its chips will run cooler.
This is evident on the FireGL V which, for the level of processing power it possesses, sports atti relatively small heat sink and fan.
The stability of the driver was excellent, though ATI was keen to point out that most individual applications were not yet optimised. Autodesk Inventor, for example, has an ageing implementation of OpenGL, and has used DirectX as its default for the past few releases.
There are five cards in total: A cynic might say this is more about getting one up on arch-rival Nvidia whose Quadro FX features 1. The Quadro FX from Nvidia was used for comparison, largely because we already had a full set of benchmark results from this mid-range card, but also because we knew it would give the FireGL V more than a good run for its money.
The benefit for the end user is that more and more processing power can be crammed into the same power envelope, which is limited by the power supply and cooling requirements of a workstation.
While ATI is pushing forward with 65nm at the low-end, it still uses 80nm fabrication for its high-end boards, primarily due to their complexity.
At Siggraph ATI unveiled its next generation unified graphics architecture. In DirectX mode in 3ds Max 9. In the past this was dealt with by dedicated geometry engines and dedicated pixel shaders. After all, it would take a hell of a lot of complex geometry and textures to fill 2GB. OpenGL performance in Inventoron the other hand, was poor, which at 1.
While DirectX has improved since Version 9 by including better support for geometry an area in which OpenGL has always been strongit still looks unlikely that CAD vendors will follow the lead of Autodesk en masse any time soon.
This meant that if your model was geometry heavy as is typical for CAD then your geometry engines could be working flat out while your pixel shaders sat around twiddling their thumbs.
