===Series2 (NEC)===
The second generation '''PowerVR2''' ("PowerVR Series2", chip codename "CLX2") was brought to market in the [[Dreamcast]] console between 1998 and 2001. As part of an internal competition at [[Sega]] to design the successor to the [[Sega Saturn|Saturn]], the PowerVR2 was licensed to NEC and was chosen ahead of a rival design based on the [[3dfx]] [[Voodoo2]]. It was called "the Highlander Project" during development.<ref>{{cite magazine |title=Power VR Prepares Highlander |magazine=[[Next Generation (magazine)|Next Generation]]|issue=34|publisher=[[Imagine Media]] |date=October 1997|page=20}}</ref> The PowerVR2 was paired with the [[Hitachi SH-4]] in the Dreamcast, with the SH-4 as the [[T&L]] geometry engine and the PowerVR2 as the rendering engine.<ref name="Unified">{{cite journal|last1=Hagiwara |first1=Shiro |last2=Oliver |first2=Ian |title=Sega Dreamcast: Creating a Unified Entertainment World |journal=IEEE Micro |publisher=[[Institute of Electrical and Electronics Engineers]] |volume=19 |number=6 |date=November–December 1999 |pages=29–35 |url=http://computer.org/micro/articles/dreamcast_2.htm |url-status=dead |archive-url=https://web.archive.org/web/20000823204755/http://computer.org/micro/articles/dreamcast_2.htm |archive-date=2000-08-23 |doi=10.1109/40.809375|url-access=subscription }}</ref> The PowerVR2 also powered the [[Sega Naomi]], the upgraded [[arcade system board]] counterpart of the Dreamcast.

However, the success of the Dreamcast meant that the PC variant, sold as Neon 250, appeared a year late to the market,<ref>{{Cite web |last=Andrawes |first=Michael |title=The Future & History of Tile Rendering - Imagination Technologies / STMicro PowerVR Series 3: KYRO |url=https://www.anandtech.com/show/558 |access-date=2024-02-20 |website=www.anandtech.com}}</ref> in late 1999. The Neon 250 was nevertheless competitive with the [[RIVA TNT2]] and [[Voodoo3]].<ref>">{{cite web | title=Sharky Extreme | website=sharkyextreme.com | date=2000-10-11 | url=http://sharkyextreme.com/hardware/reviews/video/neon250/15.shtml | archive-url=https://web.archive.org/web/20001011035118/http://sharkyextreme.com/hardware/reviews/video/neon250/15.shtml | archive-date=2000-10-11 | url-status=dead | access-date=2021-01-18}}</ref> The Neon 250 features inferior hardware specifications compared to the PowerVR2 part used in Dreamcast, such as a halved tile size, among others.

* All models are fabricated with a 250&nbsp;nm process
* All models support [[DirectX]] 6.0 
* PMX1 supports PowerSGL 2 and includes a MiniGL driver optimized for ''[[Quake III Arena]]''
