I noticed this thread: http://www.vogons.org/viewtopic.php?t=28473&postdays=0&postorder=asc&start=0 mentioned the earlier (Samuel/Ezra) C3 parts actually having the FPU running at 1/2 the core clock speed. That would at least partially explain the exceptionally poor FPU performance, though assuming …

Yes, I am referring to a C3 Nehemiah in the CPGA form-factor. http://www.chipdb.org/img-cyrix-via-c3-1.2aghz-2311.htm A bit off topic, but on the note of the ceramic package: it's a bit odd having (close to) the lowest-cost/lowest-performance new processor at the time using a relatively expensive ( …

I don't know. I only bothered to source the late generation Nehemiah since it was the best of VIA's production efforts for socket 370. Anyone with other VIA's chips, please feel free to contribute to this mini comparison. Where did you find a C7 in PPGA? I only ever find them in BGA. AFIK he's been …

I know I mentioned the issue of Cyrix's lag in going beyond 350 nm parts before, but looking again, that period (when AMD and Intel went 250 nm) is even more significant than I'd considered before. Prior to AMD and Intel's move to 250 nm parts in 1998, Cyrix's newest 6x86MX models had managed to …

I'm not sure about 2.9 vs 2.2v cores in general, but I Cyrix did make modest modifications/tweaks that slightly improved performance for later revision parts: there's a bit on that mentioned here: http://www.sysopt.com/forum/showthread.php?t=44340 Not all MII are created equal - rev. 08h is faster …

CT3600 SB32 and CT2940 SB16 for example. The title of this topic is "SB16 sounds better than AWE32". I want to comment that many SB16's have an AWE32/SB32 brother with the exact same chips, but with an additional EMU Synthesizer. If we are not talking about that EMU thing, it is not so much about …

If they were designing them for higher per clock performance, then why are they slower than Celerons at the same speed? It looks like the performance per clock is lower if it can't keep up with a Celeron, not higher. I was talking about the 6x86 and 6x86MX/MII (per the previous "Cyrix and Centaur" …

Sandra tests aren't business benchmarks. Those, like SuperPi, are synthetic tests running a loop of some sort (often AMD/Intel-tuned assembly) that doesn't necessarily mean anything for application performance.

@kool kitty89 The Nehemiah has a total of 192 KB, combined, L1/L2 cache. The manual mentions that later revision might have SMP support. I doubt this is the case, but I will test them for SMP when I have more time, that is, provided they work in any of my dual 370 boards (Asus CUV4X-DLS, Intel SAI2 …

If you were actually encoding audio/video instead of just playing it back you would see a difference. I seem to recall the C3 being weak in that area. And I was right http://www.tomshardware.com/reviews/VIA-s-C3-Hits-1-GHz,472-7.html And in the business benchmarks it also falls short http://www. …

The kingmax PC-150 is somewhat rare but there is 2 versions. Rev A cannot run at tight timings of 2-2-2 even at 133MHz, While Rev B could. Whats more rare is Tonicom PC-166MHz modules. All things said your better off with some Low CAS Crucial or Mushkin PC133 than the Kingmax. Another note if using …

My P3 1400 is good for about 1600 as well. I think you'd need phase change cooling to go much higher. I saw some crazy >2GHz results in a few-year-old Xtremesystems thread. :D Sometimes those guys like to "go retro" too. Sometimes the Tulatin Celerons are a bit more flexible with overclocks than …

The stickers should be a dead giveaway to the craptastic nature of this board before you even look at anything else. PCChips put stickers with respected name brands on top of their generic chips to make them sell better. Redhill guide has all the info on them. http://redhill.net.au/b/b-bad.html …

Are any of your chips the black-top variety? Those appear to be flip-chips with the die on top (like K6 and most/all newer CPUs) and may have better cooling properties than the traditional under-mount PGAs.

My experience with the Rage family is that they have terrible dithering effects on surfaces. Is this just the games I've played or did I have an old 16 bit color only board?

Didn't the K6-2 dramatically improve MMX performance over the K6 classic (not sure if the III or + models did any better for MMX). Depending on the benchmarks, even the K6 classic seems to fare well against a PII of similar clock speed . . K6-2 scales very badly with clock speed because of the …
