The Sega Dreamcast (ドリームキャスト) is a home video game console manufactured by Sega as a successor to the Sega Saturn. It was originally released in November 1998, becoming first machine to be released in what is now known as the sixth generation of video game consoles, sharing a platform with the PlayStation 2, Nintendo GameCube and the Xbox.

The Dreamcast was Sega's last home video game console, and was discontinued in early 2001. Roughly 10.6 million Dreamcast consoles have been sold worldwide.

An arcade counterpart to the Dreamcast exists as the Sega NAOMI.

Hardware

The Dreamcast is a small, white box with aesthetics designed to appeal to a wide-ranging audience. It was envisioned as an "128-bit" "super console", designed to leapfrog "32-bit" and "64-bit" contemporaries in the form of the PlayStation and Nintendo 64, respectively (although from a technical standpoint, its main processor deals in 32-bit or 64-bit instructions, with the 128-bit figure coming from the graphics hardware). Incidentally the Dreamcast was the last home console to use "bits" as a selling point, with processing capabilities now typically measured in other ways.

Taking design cues from the Nintendo 64 and the Sega Saturn, the Dreamcast contains four control ports, a removable modem, disc drive and an extension port (as well as the expected AV and power inputs). It is not backwards compatible with any prior Sega hardware or software (although its controller derives from the Saturn's 3D Control Pad), and operates in much the same way as the Saturn (and PlayStation) does, with a configurable settings and memory management accessed through a BIOS screen.

The Dreamcast uses a proprietary format of storage called GD-ROMs for games in order to circumvent software piracy, a strategy that ultimately backfired when the first run of discs had a high rate of defects. The format was also cracked fairly quickly (and in some cases, the pirated games were released before the legitimate versions). Sega largely had themselves to blame for the high levels of Dreamcast piracy—their use of the GD-ROM format was completely undermined by the console's support for the Mil-CD format, which allowed the console to boot from a standard CD-R. Mil-CD support was removed from the final Dreamcast revisions toward the end of the console's life.

The GD-ROM format also put the console at a disadvantage when competing against the PlayStation 2 - the PS2 used DVDs, and could therefore run DVD videos making it an inexpensive DVD player as well as a video game console. DVD-ROMs also have more storage space, allowing for bigger games (though the initial run of PS2 games used a blue CD-ROM format). Sega looked into DVD technology during the Dreamcast's development but claimed it was too expensive.

The Dreamcast was the first video game console to ship with a built-in 56k modem, with broadband adapters being made available later on in certain regions. This allowed the system to connect to the internet using a custom, fully-functional web browser and e-mail client. Many games released for the Dreamcast shipped with online play modes, the most popular being Phantasy Star Online and the Sega Sports lineup (now published under the ESPN label). Although other consoles before the Dreamcast had network gaming support, such as the Sega Saturn's NetLink and the Sega Mega Drive's XB∀ND, the Dreamcast was the first game console to include this ability out of the box and is therefore considered the first internet-enabled home game system.

The Dreamcast has a modest hacking enthusiast community. The availability of Windows CE software development kits on the Internet—as well as ports of Linux (LinuxDC) and dreamcast NetBSD operating systems to the Dreamcast—gave programmers a selection of familiar development tools to work with, even though they do not really support the high speed graphics. A homebrew minimal operating system called Kallistios offers support for most hardware, while not offering multi-tasking, which is superfluous for games. Many emulators and other tools (MP3, DivX players, and image viewers) have been ported to or written for the console, taking advantage of the relative ease with which a home user can write a CD which is bootable by an unmodified Dreamcast.

Sega released an arcade board, using the same technology as the Dreamcast, called Sega NAOMI, leading to many Dreamcast-exclusive games with a high level of arcade quality. The NAOMI has the same CPU, the Hitachi SH-4, at the same clock rate, but is more powerful in other ways, with the PowerVR CLX2 having a higher GPU clock rate, additional RAM and VRAM, higher bandwidth, and faster ROM cartridge storage. The NAOMI was, in turn, the basis for two significantly more powerful arcade systems, the Hikaru (debuted 1999) and NAOMI 2 (debuted 2000). Sega later packaged the Dreamcast into an arcade board as the Atomiswave. While the Dreamcast is not as powerful as 1997–1999 Sega arcade hardware, including the Model 3 Step 2 (debuted 1997), NAOMI, and Hikaru, the Dreamcast surpassed the Model 3 Step 1 (debuted 1996).

The Dreamcast (DC) was the most powerful home system during 1998–1999, outperforming high-end PC hardware at the time. The DC's SH-4 geometry engine calculates 1.4 GFLOPS and more than 10 MPolys/s, higher than a PC with PIII 800 (1999's strongest PC CPU) and Nvidia GF256 (1999's strongest PC GPU) which calculates 800 MFLOPS and 6.7 MPolys/s. The DC's CLX2 has an additional 200 MFLOPS for tiled rendering, and has a fillrate of 3.2 GPixels/s with opaque polygons and 500 MPixels/s (500 MTexels/s) with translucent polygons, higher than the V3 TV SE's 200 MPixels/s (400 MTexels/s) and GF256's 480 MPixels/s (480 MTexels/s). The DC's 800 MB/s CPU–GPU transmission bus is faster than the V3's 533 MB/s AGP bus (2x AGP 2.0) and has a higher effective bandwidth than the 1064 MB/s transmission bus from a PIII 800EB (133 MHz FSB) to GF256 (4x AGP 2.0) due to the DC's more efficient bandwidth usage, including its lack of CPU overhead (from operating system) and the CLX2's tiled rendering architecture: 32 bytes per polygon (less than standard 40 bytes per polygon), textures sent directly to VRAM (freeing up CPU–GPU transmission bus for polygons), 8:1 VQ texture compression (higher than V3's 4:1 compression and GF256's 6:1 S3TC compression), on-chip tile buffer (no need for Z-buffer), and deferred rendering (no need to draw, shade or texture overdrawn polygons). The CLX2 was also the first GPU to support Dot3 normal mapping, which the V3 lacked and a year before the GF256. The CLX2's rendering throughput is 7 MPolys/s, with game engine performance peaking at 5 MPolys/s; in comparison, a Celeron 300A 450 MHz (100 MHz FSB, 364 MFLOPS) with V3 TV (183 MHz) renders 750,000 polys/s, a PIII 800 (800 MFLOPS) with V3 TV SE (200 MHz) renders 1.8 MPolys/s, and a PIII 800 with GF256 has a peak rendering throughput of 6.7 MPolys/s and peak game engine performance of 2.9 MPolys/s. DC game engines rendered 50,000–166,666 polys per scene (3–5 MPolys/s), while PC game engines of 1999 rendered 10,000–15,000 polys per scene (1–1.6 MPolys/s).

Compared to the rival PS2, the PS2 is better at untextured polygons, particles, and lighting, while the DC is better at textures, anti-aliasing, and image quality. The PS2 has a more powerful CPU geometry engine (6.2 GFLOPS Emotion Engine), higher translucent fillrate (2.4 GPixels/s), and more main RAM (32 MB, compared to DC's 16 MB), while the DC has more VRAM (8 MB, compared to PS2's 4 MB), higher opaque fillrate (3.2 GPixels/s), and more GPU hardware features, with CLX2 capabilities like tiled rendering, super-sample anti-aliasing, Dot3 normal mapping, and texture compression, which the PS2's Graphics Synthesizer GPU lacks. With larger VRAM tiled rendering, the DC can render a larger framebuffer at higher native resolution (without needing Z-buffer), and with texture compression, it can compress around 20–60 MB of texture data in its VRAM. Because the PS2 has only 4 MB VRAM, it relies on the main RAM to store textures, but the PS2's CPU–GPU transmission bus for transferring polygons and textures has a bandwidth of 1.2 GB/s; while 50% faster than the DC's 800 MB/s CPU–GPU transmission bus, the DC has textures sent directly to VRAM (freeing up the CPU–GPU transmission bus for polygons), only requires 32 bytes per polygon, and texture compression gives it around 2–6 GB/s of effective texture bandwidth. DC games were effectively using 20–30 MB of texture memory (compressed to around 5–6 MB), while PS2 games up until 2003 peaked at 5.5 MB of texture memory (average 1.5 MB). PS2 game engines up until 2003 rendered up to 7.5 MPolys/s (145,000 polys per scene), with most rendering 2–5 MPolys/s (average 52,000 polys per scene); in comparison, DC game engines rendred up to 5 MPolys/s (166,666 polys per scene), with most rendering 2–4 MPolys/s (average 50,000 polys per scene). The DC is more user-friendly for developers, making it easier to develop for, while the PS2 is more difficult to develop for; this is the reverse of the 32-bit era, when the PlayStation was more user-friendly, and the Saturn more difficult, for developers.
