However, the cards are not available on the market, and it is possible that the GeForce FX 5800 Ultra will never come onto the scene (maybe only GeForce FX 5800 working at lower frequencies and the slower RADEON 9700 PRO). But the NV30 is a real step toward a very flexible programmable graphics processor. The GeForce FX has its disadvantages which were mentioned above. But they do not lay deep and I suggest that in the next chip versions of the NV3X family (first of all, NV35) the errors of the NV30 will be done away with. I have got information that the NV35 may arrive already in May. Besides, we expecting the junior brothers - NV31/34 which will also include all shader capabilities of the NV3X architecture. It's the first time we are examining the card which may not arrive into the retail market but which serves an an architectural base for a whole family of products. The already tested execution units based on the .13 technology will let quickly make and launch a whole family of new chips for various market niches. The weakest point of the GeForce FX 5800 is the 128bit memory bus because even such fast memory working at 500 (1000) MHz can't provide the required throughput for the 500MHz 8-pipeline chip. It had a very bad effect on the AA in spite of the frame buffer compression in MSAA modes. Such compression is the de-facto standard for modern processors, and even with this compression the throughput of the 128bit memory bus is not enough for storing 4000 shaded pixels per second. As a result, the NV30 has a lower speed in the AA mode than the R300 (which has both compression and the 256bit memory bus). Besides, the MSAA algorithm's quality is much higher in case of the R300. We can't estimate whether the GeForce FX 5800 Ultra is able to cover the expenses with sales because the final retail prices are unknown. Another downside is a noisy cooler which can frighten users by unexpected starts or pauses (when the rotation speed gets lower). Because of such design a user has to sacrifice the first PCI slot. But this downside can be dealt with, and there are already cards with cooling systems free of shortcomings of the reference card. So, despite the above weak points, this is the fastest 3D accelerator for the beginning of 2003. In our 3Digest we will see how the NV30 works on different driver versions and check quality and stability in games. "
