WinChip 2 comes online at IDT

WinChip 2 comes online at IDTRichard Ball
IDT has started shipping the second device in its family of x86 processors – the WinChip 2.
Aimed at the very low end of the PC market, WinChip 2 is by far the cheapest x86 device, costing $30, $35 and $38 for 200, 233 and 266MHz rated chips respectively.
Benchmarking using Winstone puts the 266MHz rated chip, actually running at 233MHz with a 100MHz bus, on a par with AMD’s K6-2 and Cyrix’s MII, both also at 266MHz.
WinChip 2 is the second x86 family to include AMD’s 3DNow instructions for speeding floating point calculations. On 3D tests, the IDT and AMD are up to 50 per cent faster than the Cyrix device, claims IDT.
This second generation device was due to appear last year, but manufacturing problems at IDT’s eight inch, 0.25?m fab held up production. The chip’s six million transistors are squeezed into 58mm2, making it small as well as cheap.
The next device, imaginatively called WinChip 3, is due for production in August. On-chip level one cache is doubled to 128kbytes, giving a ten per cent performance boost, the company claims.
WinChip 4, scheduled for late this year and early 2000, will clock along at 400 to 500MHz. Processor Speed Grade Clock MHz Bus MHz Power W When WinChip 2 200
