CPU: Various processors from Intel,AMD, Cyrix, varying from 4.77Mhz (Intel 8088) to 200Mhz (Pentium MMX) and up to 1995 (available on this site) MEMORY: 640Kb to 32MB RAM (typical up to 1996) GRAPHICS: VGA standard palette has 256 colors and supports: 640x480 (16 colors or monochrome), 640x350 in 16 colors (EGA compatability mode), 320x200 (16 or 256 colors). Later models (SVGA) featured 18bit color palette (262,144-color) or 24bit (16Milion colors), various graphics chips supporting hardware acceleration mainly for 3D-based graphics routines. SOUND: 8 to 16 bit sound cards: Ad-Lib featuring Yamaha YMF262 supporting FM synthesis and (OPL3) and 12-bit digital PCM stereo, Sound Blaster and compatibles supporting Dynamic Wavetable Synthesis, 16-bit CD-quality digital audio sampling, internal memory up to 4MB audio channels varying from 8 to 64! etc. Other notable sound hardware is the release of Gravis Ultrasound with outstanding features! MEDIA/STORAGE: 3.5" internal FDD (360kb to 1.44MB), HDD from 10MB to several hundreds more (up to 1995)
IBM and compatibles personal computers (PC) mainly used as business machines, but gained a lot of the video-games market due to their expand-ability. Systems CPU vary from Intel's 8088 based CPU to 286 (8Mhz), 386 (33Mhz), 486 (133Mhz) and Pentium S MMX (200Mhz) while their graphics can come from 4-colored CGA mode to 16-color-EGA and 256-color VGA modes of low-mid and high resolution up to 1024x768 (at that time, mid 80s to mid 90s) depending on their hardware (graphics card). Also with the installation of sound hardware (sound cards) such as the 8bit Ad-Lib series and later the 8/16bit Sound Blaster (and compatibles) and others (i.e. the advanced Gravis Ultrasound!), the PCs could offer great sound capabilities as long as their sound processors is 16 bit-based (or better) with wave-synthesis capability, multi-channel output etc. Talking for video-games here, the PC graphics and sound hardware released from mid 80s to early 90s, was not capable enough to compete with Amiga and other notable 16bit home computers. Though, just after the release of 16bit of sound cards and the standardization of VGA graphics cards (instead of EGA etc) the games on PCs became comparable and even better than the competition.
