2763.0. "Pentium or K5" by CALDEC::BOSKLOPPER () Sun Jan 26 1997 16:35

    I couldn't find anything about this topic so let me ask.
    Within a couple of weeks I need to upgrade four 486 cpus
    to pentium cpus. I have already the motherboards and need
    to buy the processors. The pentiums are still expensive
    and I saw the AMD K5 chips whitch are much cheaper.
    Has anyone knowledge or experience with the AMD chips?
    Are they compatible for 100% or are there problems?
    Any information is welcome.

2763.1	100% compatible.	JULIET::HARRIS_MA	Networks Sales Exec	`Sun Jan 26 1997 18:54`	11
	The AMD K5 chips (Not the 5x86 stuff), are always compared as TRUE Pentium class chips. They are 100% pin-pin compatible, and software and cache compatible. Cyrix chips have always been odd-balls, and somewhat different, but these AMD's are direct replacements. IMHO based on what I read, the AMD K5 is a direct replacement for any Intel Pentium. No special/different BIOS changes needed. (The only rumour I read is the Floating-point performance is slightly less than Intel's). Mark
2763.2	some problems	CSC32::J_MANNING		`Mon Jan 27 1997 17:25`	8
	I have seen at least a few reports on Usenet of apps that would fail with an AMD K5 chip but work when a Pentium chip was installed. They seem to be mostly games that are written for Verite 3D accellerator cards. It looks to be a DMA problem. John

	my .02 is: I have had a chance to save a few $$$ on AMD or Cyrix; and am currently writing this on a PODP [Intel] OverDrive chip. due to the previous .2 replies, and "stuff failing occasionally" due to cache, dma, etc errors, I decided to stick with the Intel and it's warranty; which if DMA serves me correctly is 5 years, far beyond the life of this box... See the note elsewhere in this or the ::DECSTATION conference, you can order a PODP as a reseller for pretty darned cheap. again, my .02
2763.4	Seems OK to me.	WOTVAX::SHARKEYA	LoginN - even makes the coffee@	`Wed Jan 29 1997 18:25`	5
	A friend has a K5 75Mhz processor. It seems fine and about as fast as a 120Mhz Pentium (eyeball speed checks!!_ Alan
2763.5	Works great	NETRIX::"sawyer@okemo.lkg.dec.com"	Travis Sawyer	`Tue Apr 01 1997 17:49`	11
	Greetings: I know that this is a little late in coming... I have an AMDK5pr100, I upgraded in November '96 and have had no problems (knocking REALLY hard on wood) since my upgrade. Are the K6 chips out yet??? Travis [Posted by WWW Notes gateway]
2763.6	K6 today...	JULIET::HARRIS_MA	Networks Sales Exec	`Wed Apr 02 1997 18:06`	1
	K6 announced today...
2763.7	I went for AMD	SPOOKS::BOSKLOPPER		`Sun Apr 06 1997 04:34`	6
	After all your inputs I bought an AMDk5/100 and works fine. Only when booting the bios gives me for cpu type some garbage,but for the rest it works great. Ben Palo Alto CA
2763.8	Smile be happy...	JULIET::HARRIS_MA	Networks Sales Exec	`Mon Apr 07 1997 16:17`	14
	RE: -.1 Clear indication that the motherboard does NOT directly understand the AMD parts. If you bought as a combination/package, then the vendor should swap for a newer MB. If not bought as a package, the MB maker might have a newer FLASH bios image for the MB to recognize the AMD chips. If it works, and there are no other diagnostic problems, (cache utilization and performance is OK?), then live and let live! Smile be happy! Mark
