h0rus writes, "One of the guys from Ars went to Cyrix's unveiling of their new x86 chip, the Cyrix III (codenamed "Joshua"), and wrote up a summary of what was announced. The chip looks like a pretty sweet budget/mobile x86 option: 64K L1, 256K L2, dual-pipelined FPU, Socket 370 compatible, and not clock-locked. Maybe Cyrix can redeem their name with this one. "

My next machine, after I have worn this one out plenty, will be a Crusoe-powered laptop. I have seen the light: the days of big, ugly tower cases for workstation users are numbered. Traditional cases make sense for servers, but hey! who needs expansion slots or serial ports anymore? Most of the technology has plateued and doesn't need to be upgraded often anymore (cpu speed, sound cards, video cards, ethernet, etc.) So why not by a small, fast mobile laptop??
This chip is mildly interesting but it doesn't look like it will be able to compete anywhere. It's main use will probably be as an upgrade to old PGA machines at some point. Quite a narrow market.

Here is an interesting idea (altho I doubt that it will ever happen): Motorola could buy cyrix (or better yet Transmeta) and gain access to the x86 market. They already make the chips for Macs, Palms, and many wireless devices. Transmeta looks like it may present a threat to Motorola's handhend dominance. This is especialy true if the Transmeta's chip can be set up to emulate a 68000, the chip that Motorola makes for the PalmPilot. Right now everytime someone buys a Palm Pilot it is money in Motorola's pocket. There are plenty of reasons not to do this of course (like cyrix's rep stinks to high heaven and no one has made it profitable) and I dont think the Motorola is in the mood for a radical change to their product line.

One peice of hardware I bought (soundcard or something) turned out to be incompatable with Cyrix processors. Not only that, but performance was terrible. Sure it was a nice upgrade from my 486, but compared to actual Intel machines I used, it was pretty bad. Not only that, I found out later that their 6x86 '166' wasn't actually 166Mhz. It ran at 133 and had "special features that make it run as fast as if it were 166Mhz". What a clever marketing scheme. Intel should do that too: Come out with the Pentium 1.2Ghz that only runs at 800Mhz but has "special features" so it runs as fast as if it were 1.2Ghz.
In conclusion, I vowed to never buy another Cyrix processor as long as I may live. I advise others to do the same, and not to believe their hype. Remember what they delivered in the past, and that history often repeats itself.

Re:For what it's worth (Score:3)
Then inside / around the CPU you have cache, which is a HUGE variable. You have the raw MHZ speed, you have the pipeline depth, and the latency, both of which are negatively affected by larger caches ( due to address resolution logic ). Then you have the port deth ( how many parallel accesses can the cache access ). And finally the size and bandwidth of the cache. AMD / Cyrix have gone with bigger but lower performance caches, while Intel has gone with more complex but smaller caches. Hypothetically, a larger, simpler cache will be cheaper to design, but will take up more surface area, and thus provide lower yield. To make matters worse, some programs require high speed access to a very small data-set ( and thus benifit Intel ), while other applications just use a lot of data, and anything that minimizes main memory access boosts speed. I believe Quake qualifies for the former, while Office apps ( and scripting languages in general ) benifit the latter.
AMD and Cyrix also, for a while there, worked at enhancing the internal instruction flow algorithms. Making huge branch prediction buffers, and in the case of Cyrix, producing all sorts of algorithmic optimizations that Intel strangely didn't implement.
I believe the main reason AMD and Cyrix didn't work as hard at their FPU was because it's a _really_ ugly design project. It's more fun to work on general purpose flow design and playing and tweaking a simplistic cache design, than to get dirty with all the possible combinations of floating point logic ( especially one as ugly as the 8087 family. I believe Intel owns several patents on some highly optimized implementations, so the others would have to devote some big bucks to tweak theirs without violating any laws. Not to mention, making it faster often times means taking up more silicon. Thus you have a larger die ( thus lowering yields ) and the logic is expensive to design / debug / implement to boot.
The next issue was latency. Intel, with the 80686 line ( I hate their non-informative naming conventions ), went super-pipelined, which worked great for sequential operations, but performed horribly in random branching contexts. AMD and Cyrix both opted for a narrow pipe-depth, with an emphasis on branch prediction. Thus even failed predictions had minimal penalty.
The fastest possible processor will be non-pipelined and have n-wide execution components. The reason being that each pipeline stage introduces a store and forward delay. Some stages may perform minimal operations, thus wasting 75% of a clock tick. This really hurts data-dependancy delays, since a pipelined FPU might take 15-150% longer to complete a Divide which the very next instruction requires. If all other data-dependacy paths are blocked, all the pipelining in the world won't do you any good. In the integer world, this is very common. I'm about to perform a cache missed memory fetch, but first I must calculate the address. If every other instruction is based on the contents of that memory cell, then pipelining can only hurt this particular case.
The biggest opponent to complex and optimized operations was that they would slow down the rest of the processor ( by requiring slower clock ticks ). But the device manufacturers are learning how to make different parts of the CPU run at different frequencies. ( They've long since learned how to run the BUS at a fraction of the Core ). Intel's next 80686 processor varient will have a clock doubled integer core, for example.
Still, the main reason we don't see a return to complex optimizations is that having 32 ADD components is extremly more expensive than having 2 16 deep add components. Even though you'll get a significant performance boost ( assuming you can manage that huge bus, and a potentially large number of register ports ), you probably won't make up for the added expense in shere complexity and yeild loss ( due to extra size ).
Thus, Intel went for a partially pipelined FPU which had heavy latency penalties, but improved overall operations ( especially for non data-dependant operations ).
AMD Finally headed this off by making multiple independant and fully pipelined FPU's in their Athalon. ( they spent the extra bucks to remove many of the stalling conditions caused by sharing of resources by seperate components ).
Personally I like SUN's java-multi-threaded CPU concept ( even if it never succeeds ). Basically, you have 4 parallel fully functional, non-related, non-pipelined, fully optimized functional units. There are no resource contention issues, no scheduling problems, a simplified logic design. And it's cheaper because you take away pipelining. The best part is that each of these extrememly simple components are just cookie cuts. You spend all your time tweaking the hell out of one tiny unit, then make 32 copies. Almost as easy as cache design.
I believe the Crusoe could learn from this. They already have their simplified design, they could take it a step further. Say, keep a single CPU implementation for power-critical devices. Then replicate that core 8, 16 or 32 times for a desk-top varient. Since you can control your wrapper code, you can determine what is the optimal CPU-width. I'm sure there are many cases that would allow you to submit 32 parallel instructions ( at least for the compiler ).

When the PR ratings first came out, AMD and Cyrix were pretty conservative in their ratings--AMD even rated one of their 133 Mhz chips as a "PR 75". But with insufficiently rigid definitions of "PR" and no way of enforcing them, "PR" quickly turned into Public Relations. As Cyrix watched their margins and market share shrink, they began to play fast and loose with the ratings. Eventually Cyrix chips matched their Intel counterparts only under the most ideal circumstances.

(My other low end box is an AMD-486DX4 clone that I have running FreeBSD basically to serve up a couple of CDROM drives via NFS -- Another low end machine that remains adequate to its task. I put my "Webmaster in a Nutshell" and my "Java in a Nutshell" deluxe CD-ROMs in it and then use them wherever I am on my network, from desktops to my AMD laptop [sorry, 7 machines, 4 AMDs])
