Yes, the general performance isn't going to do it any favours, I suppose. But it sounds like no-one compiled/assembled Quake for the ARM7500FE, so it remains mysterious. The memory bandwidth on the A7000+ is better than on the Risc PC, though, isn't it?Would be pretty bad, noticeably worse than the StrongARM even with hardware FP. 48 MHz of ARM7 simply isn't enough on the integer side, and as noted the FPA isn't particularly quick anyway.
I saw a video late last year, "I Built The Near Ultimate Acorn RiscPC!" that features Quake benchmarks towards the end. It suggests that the 276MHz StrongARM Risc PC (not the Kinetic) gets 11.8fps, whereas RPCEmu emulating a normal StrongARM Risc PC (you must be so proud!) gets 7.9fps.For context, Quake on a 486/66 runs at about 8 fps, and the 7000+ is going to be slower than that.
What is also informative are the figures for a 187MHz Am5x86 system, getting 15.9fps, and a 200MHz PowerPC 603e system, getting 20fps. There are plenty more figures available in this thread:
"The Ultimate 486 Benchmark Comparison"
The AMD X5 mentioned in that document is the aforementioned Am5x86 which preceded the AMD K5. Obviously, this set of benchmarks is part of an exercise to try and get 486-class processors to outperform the Pentium with some serious overclocking.
