Go up one level in this thread
at specbench you can see also results from the famouse 21264A processor: http://www.specbench.org/osg/cpu2000/results/res2000q4/cpu2000-20001204-00415.html Benchmark Reference 186.crafty Time Base 1000 Runtime Base 182 Ratio 548 Runtime 186 Ratio 538 So 182 seconds it needed to execute. Hardware Vendor: Compaq Computer Corporation Model Name: AlphaServer GS80 Model 6/731 CPU: Alpha 21264A CPU MHz: 731 FPU: Integrated CPU(s) enabled: 1 CPU(s) orderable: Up to 8 Parallel: No Primary Cache: 64KB(I)+64KB(D) on chip Secondary Cache: 4MB off chip per CPU L3 Cache: None Other Cache: None Memory: 4GB Disk Subsystem: mfs (Memory File System) Other Hardware: Ethernet So it had 32MB L2 cache in total to use (bit of cheating as usual) and it ran at 0.731 Ghz At time of testing this was of course a very fast result for crafty. the fast K7s weren't there at december 2000. Compiler used: Operating System: Tru64 Unix V5.1 (Release for GS160,GS320) Compiler: Compaq C T6.3-120-44A2I DIGITAL C++ V6.1-029-408B6 File System: mfs System State: Multi-user As we know the compiler used is much better than GCC. it is the best available compiler for alpha. When i compiled DIEP for 633Mhz alpha 21164, then i used GCC and speed was equivalent to 380Mhz PII, which says something about compiler importance. It is my belief that the big gap between micro's and these 64 bits cpu's which existed initially, was mainly because the 64 bits cpu's had excellent compilers. Nowadays the 32 bits cheap micro's have good compilers too. Let's compare some results of nearly the same processors and compilers: december 2000: Hardware Vendor: Advanced Micro Devices Model Name: Gigabyte GA-7DX Motherboard 1.2GHz Athlon processor CPU: 1.2GHz AMD Athlon processor A1200AMT3C CPU MHz: 1200 FPU: Integrated CPU(s) enabled: 1 CPU(s) orderable: 1 Parallel: No Primary Cache: 64KBI + 64KBD on chip Secondary Cache: 256KB(I+D) on chip L3 Cache: N/A Other Cache: N/A Memory: 2 x 128MB PC2100 DDR SDRAM CL2.5 Disk Subsystem: IBM DPTA 373420 ATA-66 Other Hardware: Diamond Stealth 3D PCI compiler used: Operating System: Windows 2000 Compiler: Intel C/C++ 5.0, Microsoft Visual Studio 6.0 (libraries) MicroQuill Smartheap Library 5.0 File System: NTFS System State: Default speed of crafty: 157 seconds needed. Now nearly the same thing the MP processor. For DIEP the speed of MP is the same speed as the Tbird. Hardware Vendor: Advanced Micro Devices Model Name: Tyan Thunder K7 Motherboard, 1.2GHz Athlon MP Processor CPU: 1.2GHz AMD Athlon MP AHD1200AMS3C CPU MHz: 1200 FPU: Integrated CPU(s) enabled: 1 CPU(s) orderable: 1, 2 Parallel: No Primary Cache: 64KBI + 64KBD on chip Secondary Cache: 256KB(I+D) on chip L3 Cache: N/A Other Cache: N/A Memory: 256MB PC2100 DDR SDRAM CL2 Registered Disk Subsystem: IDE IBM Deskstar DTLA-307020 Other Hardware: None Software Operating System: Windows 2000 SP1 Compiler: Intel C/C++ 5.0 build 001120 Microsoft Visual Studio 6.0 (libraries) MicroQuill Smartheap Library 5.0 File System: NTFS System State: Default seconds needed: 150 So bit newer build of compiler is 5% difference, but this could be the hardware too, because it is run on a DUAL processor with DDR ram instead of single cpu SDRAM. My guess is it is the hardware which causes this 5% improvement for the biggest part. So for the 1.33Ghz Tbird we would expect the same thing of course: March 2001: Hardware Hardware Vendor: Advanced Micro Devices Model Name: Gigabyte GA-7DX Motherboard, 1.33GHz Athlon Processor CPU: 1.33GHz AMD Athlon processor A1333AMS3C CPU MHz: 1333 FPU: Integrated CPU(s) enabled: 1 CPU(s) orderable: 1 Parallel: No Primary Cache: 64KBI + 64KBD on chip Secondary Cache: 256KB(I+D) on chip L3 Cache: N/A Other Cache: N/A Memory: 2x128MB PC2100 DDR SDRAM CL2 Disk Subsystem: IBM DPTA-373420 Other Hardware: None Software Operating System: Windows 2000 SP1 Compiler: Intel C 5.0 Microsoft Visual Studio 6.0 (libraries) MicroQuill Smartheap Library 5.0 File System: FAT32 System State: Default time needed: 141 October 2001 suddenly AMD ships a number of processors called XP in. Why? at XP1500+ the 1.33Ghz XP it scores next: 127 seconds Hardware Vendor: Advanced Micro Devices Model Name: Gigabyte GA-7DX Motherboard, AMD Athlon (TM) XP 1500+ CPU: AMD Athlon (TM) XP 1500+ CPU MHz: 1333 FPU: Integrated CPU(s) enabled: 1 CPU(s) orderable: 1 Parallel: No Primary Cache: 64KBI + 64KBD on chip Secondary Cache: 256KB(I+D) on chip L3 Cache: N/A Other Cache: N/A Memory: 2x128MB PC2100 DDR SDRAM CL2 Micron Disk Subsystem: IBM DPTA-372020 Other Hardware: None Software Operating System: Windows 2000 SP2 Compiler: Intel C/C++ 5.0.1 build 010525Z Microsoft Visual Studio 6.0 SP5 (libraries) MicroQuill Smartheap Library 5.0 File System: FAT32 System State: Default You see clearly it is the compiler causing 10% speedup within a few months. Note the same intel c++ compiler i am about to install latest 'evaluation' version from. So i hope to get back with results whether it nowadays generates legal code for diep and what speed it is.
