Been running a AMD K5 PR 166 (117 MHz!!!) in my DFi Intel 430TX AT motherboard for a week or so now & have to say I am astounded at how well it is doing, I have run a load of socket 7 CPU's in this board, AMD K6,Cyrix/IBM M1, MX, MII, Winchip C6 & intel p55C(mostly from 150mhz to 250mhz) Clock for clock the K5 seems a clear winner, even if we play the PR 166 game it seems about the best, if fact it is about equal to Cyrix 6x86L 200+(75mhz x2), at least the FPU seems a lot stronger, I know quake is really only relevant for Intel chips being so optimised for the pipelined FPU & P5 architecture but the K5 manages 24.8fps agains the 6x86l 200+'s 23.6fps, even the doom scores were close at (K5)74.02 & 76.92(6x86)so what happened here? Also Doom framerates in direct comparioson to K6 166mhz, K5 166+(117mhz)=74.02, K6 166mhz=71.96. The 6x86l was 76.92.
There doesn't seem to be a lot on the 'net about the K5 apart from the "late to market" & " couldn't clock up" stuff, so what interesting bits of info do you folk have about this chip? I see it does exceptionally well in Feiopas excellent 686 comaparison too. @133 Mhz it seems to be king of the crop as far as IPC is concerned.
I have seen vague mentions of AMD's own in house K6 design before the Nexgen buyout, does anyone have any more info on that, I can't seem to find any solid info.
Also kinda interested in the Nexgen 586 itself, never seen much info or benchmarks on these, as close as I can get to test myself is a K6 166mhz, AMD's first Nexgen chip.
Been watching a VLB board, CPU and FPU on ebay for ages(http://www.ebay.co.uk/itm/201380835095?_trksi … K%3AMEBIDX%3AIT )but the price is way out of my league, pretty sure that is more than it cost when new, plus I don't have the infrastructure for VLb, I/o cards, VGA etc, etc. are they really that rare or this this typical eBay madness?
Anyhow, interested in your thoughts on the K5, Nexgen 586 and early K6.
Best,
Chris
