Pixel shader Taking into account that too low resolutions are limited by geometry and too high ones by the memory bandwidth let’s take a look at x and x It is, in fact, a special vertex shader yes! So, now we had it – the Parhelia Although 16 texture units place this chip on a higher level, our tests will show that almost no applications can work with the multitexturing mode of “4 pipelines X 4 texture units”. Conclusion It’s very complicated to estimate the Matrox Parhelia. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1]. We will examine all settings in turn.

In case of one light source the Ti is an absolute leader. However, the low frequency of the GPU and saving on caching didn’t allow this card to catch up with the competitors despite the complete utilization of the pipeline’s potential.

Above all, the memory controller works with the new bus not very effectively. The frame buffer is in RGBA Optimized Mesh This test defines a real maximum throughput of an accelerator as far as triangles are concerned.

Remember that the current low performance of the card can rise considerably with the DirectX 9.


Next time we will check this hypothesis. Driver settings You can download this animated GIF file K to look at the summary picture of the driver settings. Here you can also notice an effect of the displacement mapping. First of all, it is a high speed of pixel shaders the situation with the 3DMark will probably be solved when a new patch for this test is developed.

Matrox Parhelia APVe

Matrox was unable to assist. It should take no more than 2 or 3 days. The Matrox’s chip has a lower fillrate but it is more efficient at the full capacity than on the R To further improve analog image quality, 5th order low-pass filters are used. Write a comment below. Have you noticed that below on the left the border of the pistol’s handle is not processed in FAA 16x?

Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1]. So G existed but could not be completed because of important people going to Nvidia.

It’s interesting that the hardware blending on the RADEON is equal to, and on the Parhelia slower than the shader one, but the difference is not significant. Even the FAA is not able to help here. There seem to be a few of the MB variety floating around on flea-bay: The rumor only had that the G and G were to appear.


Test results 2D graphics Traditionally, 2D quality is very high, at xx Hz it looks superb on both heads. We set x because exactly in this resolution the difference between cards and different texturing modes is the most discernible: And we have the overwhelming majority of accelerators which can work only with the “old” bit color.

You know quite well, that estimation of 2D quality is subjective. Finally, 2D capabilities and triple-head support. The Ti takes the lead again outscoring all the rest in the effective fillrate in all three modes.

Adaptive type of the supersampling not multisampling! Basically Matrox’s Voodoo 5. When Parhelia came, three years after G!

We didn’t expect that because it has 4 vertex shaders but enables just one. By using this site, you agree to the Terms of Use and Privacy Policy. Here is the box the card pharelka ship in: Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.
