What we did find is that a lot of people use "XStones". The Samsung SGS-19, with 4MB memory (suggested list price less than $US 3500.00), gets 63,000 XStones, with the client running on a Sun 3/60; the Sun and the SGS-19 are the only two parties on the net during the runs. We'd very much like to work with those interested in developing "meaningful" benchmarks for X Server performance. Perhaps some discussion in this newsgroup is a good way to get started on this. As for the "4 times faster" comparison, this is just marketeers doing what they think they do best. Use your favourite XStone list for comparison, though I personally wouldn't encourage this practice -- it's too reminiscent of the uninformed and irresponsible "MIPS" and "Dhrystone" comparisons made by hardware vendors a while back. >>....

AGE's track record is weak. We think it does outperform the industry performance leaders. Care to comment further? By the way, we found AGE to be every bit as concerned about the performance of the server as we were, and they put in quite a bit of effort to improve the basic X11r4 stuff, as well as to tune some of the machine dependent code to the processor and memory architecture of the Samsung SGS-19. AGE's track record with Samsung is just fine. >>The Am29000 from Advanced Micro Devices,Inc., is a proprietary 32-bit >>microprocessor featuring a reduced instruction set computer (RISC) >>architecture.

We agree. Of course, our hardware, and the code that run on it, are still standing, as far as we know. > Now I remember why I am against these Internet commercials: they > contain little valuable information.

I have a strong dislike against Internet commercials, particularly when they show up in newsgroups that I subscribe to. I would not have posted it either, but AMD thought that there might be some interest in this group (presumably those interested in X terminal technology) to the announcement. -- Peter J.
