Hi all, I tried to gather some numbers so one can compare the graphic performance of 32bit vs. 64bit slot. I did "x11perf -all" on a PWS 500a, Debian Linux 2.4.20, Xfree 4.2.1, ATI Radeon with DRI. Here are the results from x11perfcomp: lentferj@neslonek:~$ x11perfcomp -r ati32bit ati64bit 1: ati32bit 2: ati64bit 1 2 Operation -------- ----------------- ----------------- 2140000.0 4880000.0 ( 2.28) Dot 1170000.0 1190000.0 ( 1.02) 1x1 rectangle 1170000.0 1180000.0 ( 1.01) 10x10 rectangle 32700.0 32700.0 ( 1.00) 100x100 rectangle 1520.0 1530.0 ( 1.01) 500x500 rectangle 691000.0 715000.0 ( 1.03) 1x1 stippled rectangle (8x8 stipple) 633000.0 632000.0 ( 1.00) 10x10 stippled rectangle (8x8 stipple) 10500.0 10900.0 ( 1.04) 100x100 stippled rectangle (8x8 stipple) 350.0 352.0 ( 1.01) 500x500 stippled rectangle (8x8 stipple) 683000.0 714000.0 ( 1.05) 1x1 opaque stippled rectangle (8x8 stipple) 673000.0 690000.0 ( 1.03) 10x10 opaque stippled rectangle (8x8 stipple) 18400.0 18000.0 ( 0.98) 100x100 opaque stippled rectangle (8x8 stipple) 839.0 749.0 ( 0.89) 500x500 opaque stippled rectangle (8x8 stipple) 678000.0 696000.0 ( 1.03) 1x1 tiled rectangle (4x4 tile) 667000.0 685000.0 ( 1.03) 10x10 tiled rectangle (4x4 tile) 18400.0 18100.0 ( 0.98) 100x100 tiled rectangle (4x4 tile) 748.0 749.0 ( 1.00) 500x500 tiled rectangle (4x4 tile) 709000.0 720000.0 ( 1.02) 1x1 stippled rectangle (17x15 stipple) 664000.0 674000.0 ( 1.02) 10x10 stippled rectangle (17x15 stipple) 11000.0 11000.0 ( 1.00) 100x100 stippled rectangle (17x15 stipple) 363.0 363.0 ( 1.00) 500x500 stippled rectangle (17x15 stipple) 709000.0 713000.0 ( 1.01) 1x1 opaque stippled rectangle (17x15 stipple) 679000.0 700000.0 ( 1.03) 10x10 opaque stippled rectangle (17x15 stipple) 18400.0 18500.0 ( 1.01) 100x100 opaque stippled rectangle (17x15 stipple) 746.0 785.0 ( 1.05) 500x500 opaque stippled rectangle (17x15 stipple) 708000.0 724000.0 ( 1.02) 1x1 tiled rectangle (17x15 tile) 679000.0 698000.0 ( 1.03) 10x10 tiled rectangle (17x15 tile) 18300.0 18500.0 ( 1.01) 100x100 tiled rectangle (17x15 tile) 731.0 785.0 ( 1.07) 500x500 tiled rectangle (17x15 tile) 737000.0 752000.0 ( 1.02) 1x1 stippled rectangle (161x145 stipple) 692000.0 692000.0 ( 1.00) 10x10 stippled rectangle (161x145 stipple) 12800.0 12500.0 ( 0.98) 100x100 stippled rectangle (161x145 stipple) 400.0 407.0 ( 1.02) 500x500 stippled rectangle (161x145 stipple) 740000.0 755000.0 ( 1.02) 1x1 opaque stippled rectangle (161x145 stipple) 721000.0 731000.0 ( 1.01) 10x10 opaque stippled rectangle (161x145 stipple) 18900.0 19300.0 ( 1.02) 100x100 opaque stippled rectangle (161x145 stipple) 805.0 847.0 ( 1.05) 500x500 opaque stippled rectangle (161x145 stipple) 740000.0 754000.0 ( 1.02) 1x1 tiled rectangle (161x145 tile) 720000.0 737000.0 ( 1.02) 10x10 tiled rectangle (161x145 tile) 18900.0 18300.0 ( 0.97) 100x100 tiled rectangle (161x145 tile) 805.0 788.0 ( 0.98) 500x500 tiled rectangle (161x145 tile) 739000.0 755000.0 ( 1.02) 1x1 tiled rectangle (216x208 tile) 725000.0 742000.0 ( 1.02) 10x10 tiled rectangle (216x208 tile) 18300.0 17600.0 ( 0.96) 100x100 tiled rectangle (216x208 tile) 808.0 782.0 ( 0.97) 500x500 tiled rectangle (216x208 tile) 1080000.0 1160000.0 ( 1.07) 1-pixel line segment 1240000.0 1280000.0 ( 1.03) 10-pixel line segment 427000.0 428000.0 ( 1.00) 100-pixel line segment 86300.0 86500.0 ( 1.00) 500-pixel line segment 424000.0 439000.0 ( 1.04) 100-pixel line segment (1 kid) 328000.0 352000.0 ( 1.07) 100-pixel line segment (2 kids) I put the graphic card in the lower one of the two 64bit slot. Would it make any difference it I put in the upper of the two? Cheers, Jan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
