16-bit vs 32-bit Performance

As a result of the Kyro II's internal 32-bit rendering, we were not surprised to find that this card actually had the least performance increase when going from 32-bit to 16-bit. Doing this comparison, however, is a bit unfair, since the 16-bit quality of the Kyro II is noticeably better than the 16-bit quality of competing cards. It is unfortunate, however, that almost no speed can be gained by falling back on 16-bit color mode. At least the speed that is gained will look better than the alternatives.

Same story when going from 1600x1200x32 to 1600x1200x16. The only card to show less of a performance increase than the Kyro II is the ATI Radeon DDR, which gains a mere 2 FPS by decreasing color depth.

    Thanks for the stroll down memory lane (by keeping the article up). I had one of these cards back in 2002, and it was one I looked back upon fondly. I can't remember most of the GPUs I owned from yesteryear, save the Voodoo 3 and the crappy S3 Verge. That's fairly elite company, at least in my brain, anyway. :)

    Yea, it's sad that there wasn't any further development of the Kyro series in the PC market. If I remember right (probably needs fact checked) Imagination's development resources got sucked into the Sega Dreamcast after this point. Even that wouldn't have been so bad if Sega hadn't just given up on the Dreamcast so early on due to a "poor showing in Japan" (nevermind everyone loved it in the US but we didn't count apparently, also see Genesis/MegaDrive).

    I think Imagination or at least their tech lives on in the embedded/mobile space now, but meh - really wanted to see what they could have done with their tech without being shackled to a power budget in 2002-2005 era PC's.

    You're wrong. The Dreamcast was designed years earlier using PowerVR Series 2. The later "Kyro series" was based on Series 3. The DC design win netted them some much needed cash which they used to fuel their Series 3 releases. What killed imgtech was their inability to play well with others (board partners) and issues staying on schedule for releases. If they had managed to get the 4800 out the door sooner, and released the larger Kyro III with DDR it would have bought them some time. Especially if they had paired it with a hardware T&L block like Elan.

    Its very interesting to think that Imagination Technologies could have been another foot note in history (3dfx, bitboys Oy! Rendition..) but going mobile and refining their technology has allowed them to basically become more popular than ATI(AMD) or Nvidia. There are probably more devices in peoples houses running a powervr variant than have an AMD or Nvidia GPU.

    I do wish someone would stick their chip on a discrete card again, they apparently support full Directx and OpenGL! could be an interesting low profile, low end, low power, fanless card for HTPCs.
