I was only arguing while someone wants to use a slower car or not - so if there are uses for a .Net engine aswell.
Just checked two things:
- For the original versions GCC is really half the speed at an actual gameplay as the Intel one. You are correct to say to use big depth searches - by plainly just checking the benchmark tests the GCC version performs in fact 20-30% better (maybe 16 * depth 12 is crappy, but I was scammed by only looking at the benchmark, it should be at similar ratio). So in fact the GCC is a garbage when it comes to actual gameplay. Wonder how that looks on i7.
- I ran a game between the 2.2.2 intel non-SSE version and the port at relative high depths (25+), but I saw no significant speed changes regarding nps after 20+. The performance ratio is between 2.8-3 in these cases (as I wrote earlier, 1:3 in gameplay, but lately I made small optimizations). This is an i5 laptop, original delivers in ranges 2600-3000 nps and the port around 880-960.
Obviously this should be just some bull**** as there is a huge amount of concurrent memory allocation and the garbage collection is under constant stress and the code is 100% safe, blablabla. But it isn't and this difference is what I put a lot of work into. I plan to tidy up things first before doing a release and I'm in no rush, so it might the wise to stop corresponding before there actual facts one is able to validate as it should be.
I don't care about the politics, just enjoy the task trying to deliver exceptional performance in this technology.
Cheers, Balint |
