Ars Technica heeft een artikel in elkaar gedraaid met erg veel benchmarks van de K6-III, PIII en Celeron. Er werd o.a. getest met Winstone99, 3DMark99, Quake II en Unreal. Hier een stuk uit de conclusie:
All in all, AMD's latest looks to be competitive once again with the latest generation of Intel processors. For those who want blistering performance on everyday applications like MS Office or Netscape, any of these chips will do. However, a K6-III will really, really do; it's a real screamer in these sorts of applications, and it's not shy of the 32-bit environment of Windows NT, either. (I'm willing to venture it'll go like stink with Linux or the BeOS, as well.)
That said, the K6-III looks like a mixed bag for other types of performance, such as gaming and other floating-point-intensive apps. If you get the right 3D card with the right driver optimizations, for instance, 3DNow could pay off. NVIDIA is, I believe, working on 3DNow optimizations for their TNT and TNT2 drivers, and 3dfx led in this area in the past, in part due to help from AMD. Still, depending on developers to integrate 3DNow SIMD support is likely going to be a constant, frustrating vigil for the enthusiast--especially now that Intel is pushing its own SSE as an alternative.
