In bit color the situation is similar to the previous test. That’s because video cards are meant to play games Obviously done for the sake of cooling, not like it’s there to make toast. The KYRO based cards cost today even less than the GeForce2 MX, that is why the only obstacle in the way of popularization of these cards is a small number of companies which are producing them.

BioShock Infinite and Metro: Quake 3 tells the same story: User Manual; CD with drivers and utilities.

The card doesn’t follow the reference design from Imagination Technologies. I just don’t recommend to enable the texture compression on the games based on the UnrealTournament engine.

The concept of the KYRO combines simplicity of the cards, cheap SDR memory, and at the same time, quite high speed results as compared with their competitors, and strong diversity of the performance in different games.

That is why the memory has a good overclocking potential, but it is, unfortunately, limited by the chip’s speed.

We have already written that the peculiarities of the architecture of this chip doesn’t allow for lifting the frequency. I’ve included Kyro 2 numbers so you can directly compare the two chipsets. In bit color the situation is similar to the kryo test. However, activation of the S3TC together with the trilinear filtering makes the losses of the latter smaller.


Why do the drivers pass a debugging process only for several popular games? If you’re on a really tight budget and you’re buying retail, look no further than the XT. The bit color has brought nearly the victory to the KYRO!

Video 3Digests Video cards: Minimum framerates dip lower on the Kyro-based cards, but the maximum framerates are also higher than the others. And we shouldn’t ignore video cards on this chipset, first of all, due to their low price.

That’s because video cards are meant to play games Switching out a couple of different drivers, I eventually settled on 7. I’d hope they’d fix the problem but haven’t had a chance to test them out yet. Strong performance fall when the trilinear and anisotropic filtering are enabled; Lack of anisotropic filtering in the OpenGL; Low quality of the anisotropy in the Direct3D. Surprisingly enough, in 3D Markthe Kyro 1 and 2 aren’t very far apart.

But the S3TC bears fruit, and the gap is not so critical! Besides, this PCB has a smaller size. If you’re going to be playing games in the lower resolutions, that is, x or x, and considering this is a low-end video card I wouldn’t recommend playing in the higher resolutions anywayyou’ll get acceptable performance levels. After that they write letters with suggestions to test the KYRO cards again.

In our 3Digest in the S3TC part I am studying this issue in detail, that is why I recommend you to read this material, where you can also look at the screenshots and make sure that the kyor of the texture compression worsens the quality of the KYRO to the least extent among all 3D chips.


It is based on the original Kyro graphics chip, kydo one that came before the Kyro 2 used in the Prophet that we reviewed nearly five months ago and is as such, considered to be previous-generation hardware. In X at 75 one can see a sharp image.

Quake3 Arena demo, standard settings The tests were carried out in two modes: Conclusion I must only add to the words said above that activation of the S3TC in the Direct3D doesn’t practically worsen the quality the most of errors are corrected in the latest versions of the drivers.

Here the results are somewhat different.

Fast shows card’s work in bit color and High Quality shows card’s work in bit color. 4000xf, there are some drawbacks connected with the KYRO’s architecture: The Kyro 1 is essentially the same as the Kyro 2, so you can always see that review for more specific details on the technology behind the silicon. Consumed Power, Energy Consumption: A buyer of such a card must has an Internet access all the time to update the software.
