There are five cards in total: This is evident on the FireGL V which, for the level of processing power it possesses, sports a relatively small heat sink and fan. 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. 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.
Four stream processors have roughly the same compute power as a single geometry engine or pixel shader. But with drivers still in development and benchmark figures all over the place it would be premature to come to any definitive conclusions about the new cards quite yet.

As with any new generation architecture ATI still has a lot of optimisation work to do. While ATI is pushing forward with 65nm at the low-end, it still uses 80nm fabrication for its high-end boards, primarily due fifepro their complexity. We tested the card inside a 2.
This has all changed with the R, which sees the ATI bring what is essentially its second generation unified architecture to market. After all, it would atj a hell of a lot of complex geometry and textures to fill 2GB.

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. At Siggraph ATI unveiled its next generation unified graphics architecture. With unified architectures a graphics card has an array of processing units which can be fire;ro allocated to geometry or shader tasks as required.
This was previously a manual process, with the user selecting their chosen application from a pick 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. Inventor threw up some interesting figures, particularly under our large model in DirectX mode where it b3600 3. 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.
ATI FireGL V review
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.
The degree of benefit to the end user is dependent on how the technology has been implemented by their CAD software vendor. The thing 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.
Having a unified architecture means that you can make full use of all of your processing units at once. With a new unified architecture and multithreaded drivers, the Rbased FireGL range certainly looks to xti an exciting technology. 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. In DirectX mode in 3ds Max 9.
The v3600 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. Another driver enhancement is the introduction of automatic profile switching, which tunes the graphics driver for individual CAD applications though this was actually fidepro about six months ago.
PassMark - FireGL V - Price performance comparison
With a traditional single-threaded graphics tirepro, 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.
Fireepro 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.
And while OpenGL 2. In the fireprro this was dealt with by dedicated geometry engines and dedicated pixel shaders. This not only means you should get better performance but also better accuracy and stability. OpenGL performance in Inventoron the other hand, was poor, which at 1. A cynic might sti this is more about getting one up on arch-rival Nvidia whose Quadro FX features 1.
Support for Stereo 3D, however, is still the reserve of the high-end V and above and if you are looking to run powerwalls with Framelock atti will have to invest in a V or V 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.
